  • Homicide in discharged patients with schizophrenia and other psychoses : a national case-control study.
  • 2010
  • Ingår i: Schizophrenia Research. - : Elsevier BV. - 0920-9964 .- 1573-2509. ; 123:2-3, s. 263-9
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To investigate factors associated with homicide after discharge from hospital in patients with schizophrenia and other psychoses.DESIGN: All homicides committed by patients with psychosis within 6 months of hospital discharge were identified in Sweden from 1988-2001 and compared with patients with psychoses discharged over the same time period who did not subsequently commit any violent offences. Medical records were then collected, and data extracted using a validated protocol. Interrater reliability tests were performed on a subsample, and variables with poor reliability excluded from subsequent analyses.RESULTS: We identified 47 cases who committed a homicide within 6 months of discharge, and 105 controls who did not commit any violent offence after discharge. On univariate analyses, clinical factors on admission associated with homicide included evidence of poor self-care, substance misuse, and being previously hospitalized for a violent episode. Inpatient characteristics included having a severe mental illness for one year prior to admission. After-care factors associated with homicide were evidence of medication non-compliance and substance misuse. The predictive validity of combining two or three of these factors was not high. Depression appeared to be inversely associated with homicide, and there was no relationship with the presence of delusions or hallucinations.CONCLUSIONS: There are a number of potentially treatable factors that are associated with homicide in schizophrenia and other psychoses. Associations with substance misuse and treatment compliance could be the focus of therapeutic interventions if validated in other samples. However, their clinical utility in violence risk assessment remains uncertain.

  • Psychological and Sociocultural Adaptation of Children Adopted from Russia and their Associations with Pre-Adoption Risk Factors and Parenting
  • 2017
  • Ingår i: Journal of Child and Family Studies. - : SPRINGER. - 1062-1024 .- 1573-2843. ; 26:10, s. 2669-2680
  • Tidskriftsartikel (refereegranskat)abstract
    • We investigated academic and behavioral outcomes of internationally adopted children and the associations between these outcomes and age at adoption, time spent in the adoptive family, and parenting. At two time points (T1 and T2, similar to 15 months apart), we examined early academic skills (school readiness), and parent-reported behavioral adjustment (internalizing and externalizing behavior) and adaptive functioning of a sample of 75 children (45.9% boys, mean age = 5.17 years) adopted from Russia into US families. We also collected parents' self-assessments of their parenting at T1. Children who were adopted at a younger age showed higher levels of early academic skills. Correlations between age at adoption and other outcomes were overall small and mostly non-significant. However, adoptees' academic and behavioral progress differed notably in several respects. Specifically, adoptees improved in early academic skills over time, whereas, as a group, their adaptive functioning and behavioral adjustment remained stable within the normal range. Early academic skills were not related to behavioral adjustment at each time point and over time. The time spent in the adoptive family was positively related to early academic skills at T2. Whereas outcomes showed little to no relation to parenting as reported by mother and father separately, higher discrepancies between mothers' and fathers' reports of positive parenting were related to higher levels of behavioral symptoms and lower levels of adaptive skills at T2. These differential results may be explained in part by drawing upon the notion of dissociated domains of psychological and sociocultural adaptation and acculturation, outlined in the immigration literature. These results also bring to light the possible importance of between-parent consistency in parenting for adoptees' behavioral outcomes.

  • Evaluation of Birth Weight and Neurodevelopmental Conditions Among Monozygotic and Dizygotic Twins.
  • 2023
  • Ingår i: JAMA Network Open. - : American Medical Association (AMA). - 2574-3805. ; 6:6, s. e2321165-
  • Tidskriftsartikel (refereegranskat)abstract
    • IMPORTANCE: Low birth weight is associated with an increased likelihood of neurodivergence and neurodevelopmental conditions (NDCs) such as autism, attention-deficit/hyperactivity disorder (ADHD), and intellectual disability. However, it is unclear whether birth weight contributes independently to NDCs or whether the association is predominantly driven by genetic predisposition.OBJECTIVE: To estimate the associations between birth weight and dimensional (trait) and categorical (diagnoses) NDC outcomes, while adjusting for genetic risks.DESIGN, SETTING, AND PARTICIPANTS: A co-twin design was applied to this case-control study conducted in Sweden. Diagnostic assessments were conducted between August 2011 and March 2022, within the Roots of Autism and ADHD Twin Study in Sweden (RATSS) during a 2.5-day participant visit to the clinic. The RATSS sample comprised phenotyped monozygotic and dizygotic twins enriched for NDCs. Data analysis was conducted in November 2022.EXPOSURE: Birth weight.MAIN OUTCOMES AND MEASURES: Categorical and dimensional operationalizations of autism, ADHD, and intellectual disability were assessed. Generalized estimating equation models were fitted across and within twin pairs.RESULTS: The study sample included 393 twins: 230 were monozygotic and 159 were dizygotic (zygosity was unknown for 4). Their median age was 15 (range, 8-37) years. There were 185 female participants (47.1%) and 208 male participants (52.9%). Across twin pairs, higher birth weight was associated with fewer autistic traits (unstandardized β [B], -5.51 [95% CI, -10.09 to -0.94]) and lower odds of autism diagnosis (OR, 0.63 [95% CI, 0.45 to 0.88]) and intellectual disability (OR, 0.42 [95% CI, 0.19 to 0.92]). Within pairs, the association between birth weight and dimensional autism (B, -17.35 [95% CI, -28.66 to -6.04]) and categorical autism (OR, 0.02 [95% CI, 0.001 to 0.42]) remained among monozygotic pairs but not dizygotic pairs. In addition, higher birth weight was associated with lower odds of ADHD diagnosis (OR, 0.003 [95% CI, 0 to 0.70]), fewer ADHD traits (B, -0.25 [95% CI, -0.39 to -0.11]), and higher IQ ratings (B, 7.43 [95% CI, 1.05 to 13.82]) among monozygotic twins.CONCLUSIONS AND RELEVANCE: The findings of this co-twin study suggest an association between low birth weight and NDCs, but they also acknowledge the importance of genetics because the associations observed were only statically significant among monozygotic twins. It is of pivotal importance to facilitate early identification of factors contributing to fetal growth restriction to minimize detrimental outcomes.

  • Exploring possible association between DβH genotype (C1021T), early onset of conduct disorder and psychopathic traits in juvenile delinquents.
  • 2016
  • Ingår i: European Archives of Psychiatry and Clinical Neuroscience. - : Springer Science and Business Media LLC. - 0940-1334 .- 1433-8491. ; 266:8, s. 771-773
  • Tidskriftsartikel (refereegranskat)abstract
    • Early onset of conduct disorder (CD) with callous-unemotional traits has been linked to low levels of dopamine β-hydroxylase (DβH), an enzyme involved in dopamine turnover. The C1021T polymorphism in the DβH gene is a major quantitative-trait locus, regulating the level of DβH. In this study of juvenile delinquents from Northern Russia (n = 180), the polymorphism at -1021 was associated neither with early-onset CD nor with psychopathic traits. Association was found between psychopathic traits and early-onset CD, ADHD and mania.

  • Nonshared environmental factors in the aetiology of autism and other neurodevelopmental conditions : a monozygotic co-twin control study.
  • 2022
  • Ingår i: Molecular autism. - : Springer Nature. - 2040-2392. ; 13:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: A significant proportion of variation in likelihood of neurodevelopmental conditions (NDCs) has been attributed to nonshared environmental (NSE) factors, although it remains unclear which NSE factors pose specific risks for certain NDCs.METHODS: A monozygotic co-twin design was applied in a sample of 224 twins (mean age = 17.70 years, SD = 6.28) controlling for confounders such as genes and shared environment. Generalized estimating equation models were fitted, using perinatal and postnatal indications of NSEs as exposure, operationalized both as separate risk factors and as cumulative risk loads. Categorical and dimensional operationalizations of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), intellectual disability and other NDCs were used as outcomes.RESULTS: Birth weight discordance was associated with dimensional autism and ADHD for the smaller twin, and medication during infancy was associated with dimensional autism. Among postnatal factors scarlet fever during early childhood was associated with lower IQ. Especially autism was associated with a greater cumulative perinatal or postnatal risk load.LIMITATIONS: When exploring the associations between each condition and specific NSEs the risk of being statistically underpowered increases. Hence, we limit the reported findings on specific indicators of NSEs to trait levels and present descriptive data for categorical NDCs.CONCLUSIONS: The findings support previous research by indicating an association between exposure to perinatal and postnatal risks and subsequent NDCs within twin pairs and suggest that autism may be especially linked to accumulative early environmental risks. The findings are potentially important for developmental outcomes prognoses and may inform targeted prevention and early interventions.

  • Risk Factors Associated with Alcohol Use in Early Adolescence among American Inner-City Youth : A Longitudinal Study
  • 2020
  • Ingår i: Substance Use & Misuse. - : Taylor & Francis Group. - 1082-6084 .- 1532-2491. ; 55:3, s. 358-366
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Early alcohol use is associated with an increased risk for later alcohol dependence, as well as social and mental health problems. In this study, we investigate the risk factors (internalizing and externalizing behaviors) associated with early alcohol consumption over a period of 1 year, and examine whether the association is sex-specific. Methods: U.S. inner-city adolescents (N = 1785, Mean age = 12.11) were assessed and reassessed in the sixth and seventh grades (Mean age = 13.10). Self-reported information was obtained on the lifetime level of alcohol consumption, internalizing (depression, anxiety and posttraumatic stress [PTS]), and externalizing behaviors (sensation seeking, conduct problems and affiliation with delinquent peers). Associations between the variables were examined using structural equation modeling (SEM). Results: In an adjusted SEM analysis drinking by the sixth grade was primarily associated with externalizing behaviors, whereas PTS was linked to lower levels of alcohol consumption. In addition, alcohol consumption and greater externalizing behaviors by the sixth grade predicted higher alcohol consumption by the seventh grade, whereas anxiety and African American ethnicity were associated with less alcohol consumption. No sex differences were found in the association between internalizing and externalizing behaviors and drinking. However, in the adjusted SEM analysis female sex predicted higher lifetime consumption by the seventh grade. Conclusion: Sensation seeking behavior, conduct problems and affiliation with delinquent peers should be regarded as risk factors and taken into consideration when planning prevention efforts in order to decrease alcohol use in early adolescence.

  • Risky sexual behaviour among Russian adolescents : association with internalizing and externalizing symptoms
  • 2021
  • Ingår i: Child and Adolescent Psychiatry and Mental Health. - : BioMed Central. - 1753-2000. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Risky sexual behaviour (RSB) is regarded as a major health problem during adolescence. Russia has one of the highest rates of teenage pregnancy, abortion and newly diagnosed HIV infections in the world, but research on RSB in Russian youth has been limited. To address this deficit, this study examined the role of several factors, including internalizing and externalizing symptoms, in RSB among Russian adolescents. Methods: Self-reported data were collected from 2573 Russian adolescents aged 13–17 years old (59.4 % girls; Mean age = 14.89) regarding RSB (unprotected sex, early pregnancy, multiple sexual partners and substance use during sexual encounters). Information was also obtained on externalizing (conduct problems and delinquent behaviour) and internalizing (depression, anxiety and posttraumatic stress) symptoms, as well as interpersonal risk and protective factors (affiliation with delinquent peers, parental involvement and teacher support). Hierarchical multiple binary logistic regression analysis was used to examine the associations between these variables and RSB. Results: Boys reported engaging in more RSB than girls. Externalizing symptoms and affiliation with delinquent peers were most strongly associated with RSB, whereas symptoms of anxiety were negatively associated with RSB. There was an interaction effect for sex and affiliation with delinquent peers on RSB with boys reporting RSB when having more delinquent peers. Neither parental involvement nor teacher support were protective against RSB. Conclusions: Early detection of and interventions for RSB and associated externalizing symptoms may be important for adolescent physical and mental wellbeing. Affiliation with delinquent peers should, especially among boys, be regarded as a risk marker for RSB.

  • The danger of being inattentive – ADHD symptoms and risky sexual behaviour in Russian adolescents
  • 2018
  • Ingår i: European psychiatry. - : Elsevier. - 0924-9338 .- 1778-3585. ; :47, s. 42-48
  • Tidskriftsartikel (refereegranskat)abstract
    • AbstractBackground Prior research has indicated that attention-deficit/hyperactivity disorder (ADHD) symptoms may be associated with an increased likelihood of engaging in risky sexual behaviour (RSB). However, research on this association among adolescents has been comparatively limited and mainly confined to North America. The aim of this study was to examine if inattention and hyperactivity/impulsivity symptoms were linked to RSB in a community cohort sample of Russian adolescents. Methods The study was based on a group of 537 adolescents from Northern Russia. Information on inattention and hyperactivity/impulsivity as well as conduct problems was obtained through teacher ratings, while information on RSB (previous unprotected sex, number of sexual partners, sex while intoxicated and partner pregnancies), substance use, perception of risk, and parenting behaviour was based on students’ self-reports. Binary logistic regression analysis was used to examine associations between the variables. Results Teacher-rated inattention symptoms predicted RSB, independently of co-morbid conduct problems, substance use, risk perception, and different parenting styles (parental warmth, involvement and control). In addition, male sex, binge drinking and a lower assessment of perceived risk were all significantly associated with RSB in an adjusted model. Neither teacher-rated hyperactivity/impulsivity symptoms nor conduct problems were linked to RSB in the full model. Conclusions Deficits in planning and organizing behaviours, being easily distracted and forgetful seem to be of importance for RSB in Russian adolescents. This highlights the importance of discriminating between different types of ADHD symptoms in adolescence to prevent risk behaviours and their potentially detrimental outcomes on health and well-being.

  • The Role of Gender in the Associations Among Posttraumatic Stress Symptoms, Anger, and Aggression in Russian Adolescents
  • 2020
  • Ingår i: Journal of Traumatic Stress. - : John Wiley & Sons. - 0894-9867 .- 1573-6598. ; 33:4, s. 552-563
  • Tidskriftsartikel (refereegranskat)abstract
    • Symptoms of posttraumatic stress disorder (PTSD) have been linked to anger and aggressive behavior in adult and veteran populations. However, research on the associations among anger, aggression, and PTSD in adolescents is lacking, particularly regarding differences between the sexes. To address this research gap, we used self-report data from Russian adolescents (N = 2,810; age range: 13-17 years) to perform a full path analysis examining the associations between PTSD symptoms and the emotional (anger traits) and cognitive (rumination) components of anger as well as physical/verbal and social aggression, after adjusting for depressive symptoms. We also examined the interaction effects between PTSD symptoms and sex on anger and aggression. The results indicated that girls scored higher on measures of anger and PTSD symptoms, ds = 0.20-0.32, whereas boys scored higher on measures of physical and verbal aggression, d = 0.54. Clinical levels of PTSD symptoms were associated with anger rumination, β = .16, and trait anger, β = .06, and an interaction effect for PTSD symptoms and sex was found for aggression, whereby boys with clinical levels of PTSD symptoms reported more physical/verbal and social aggression, βs = .05 and .20, respectively. Our findings suggest that PTSD symptoms may have an important impact on anger, anger rumination, and aggression during adolescence. In particular, boys seem to have an increased risk for aggressive behavior in the presence of PTSD symptoms. The present results highlight the importance of taking anger and aggression into account when evaluating PTSD.

  • Longitudinal associations between community violence exposure, posttraumatic stress symptoms, and eating disorder symptoms
  • 2024
  • Ingår i: Journal of Eating Disorders. - : BioMed Central (BMC). - 2050-2974. ; 12:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Eating disorder (ED) symptoms have been associated with different types of traumatic events, such as exposure to sexual and physical violence, and emotional abuse. However, the relation between ED symptoms and community violence exposure (CVE) is underexplored, despite the latter's adverse effects on many aspects of adolescent functioning. The primary aim of this study was to evaluate the relation between CVE and ED symptoms in adolescents, while also investigating the potential mediating and moderating roles of posttraumatic stress (PTS) symptoms, gender, and ethnicity.METHODS: Data were collected longitudinally over two consecutive years in the city of New Haven, CT, in the United States. Participants were 2612 adolescent students from the public school system (1397 girls and 1215 boys) with an average age of 12.8 years (SD = 1.29). The students were comprised of several different ethnic groups, including Caucasians, African Americans and Hispanic Americans. Associations between CVE (no exposure, witnessing, and victimization) and PTS symptoms at year one, and ED symptoms (thoughts and compensatory behaviors) at year two, were assessed with self-rating instruments. Moderation and mediation analyses were conducted using a variant of linear regression (Hayes PROCESS macro).RESULTS: ED symptoms at year two were significantly associated with both witnessing and being a victim of community violence at year one, with most or all of the relations being explained by PTS symptoms. Overall, neither gender nor ethnicity had a meaningful moderating effect in the observed relations.CONCLUSIONS: The findings support the notion that assessing and addressing PTS symptoms might be beneficial when treating individuals with ED symptoms who have experienced community violence, irrespective of gender or ethnicity.

  • Bulimia Symptoms in Russian Youth : Prevalence and Association With Internalizing Problems
  • 2022
  • Ingår i: Frontiers in Psychiatry. - : Frontiers Media S.A.. - 1664-0640. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundThere has been limited research on bulimia symptoms in adolescents from the general population outside the United States. This study aimed to evaluate the prevalence of bulimia symptoms in Russian youth and explore the associations between a clinical level of self-reported probable bulimia nervosa (BN) and internalizing problems, binge drinking and functional impairment by gender. MethodsData were collected from a representative sample of school students (N = 2,515, 59.5% female) from Northern Russia [age M (SD) = 14.89 +/- 1.13 years]. Probable BN and internalizing psychopathology were assessed using self-report scales. Chi-square and independent sample t-tests were used to compare respondents' demographic characteristics and disordered eating behaviors. GLM multivariate analysis of covariance was used to assess the associations between probable BN, functional impairment and mental health problems (MHP) by gender. ResultsAnalyses showed that the 3-month prevalence of probable BN was higher in girls (3.9%) than in boys (1.2%). Probable BN was associated with depressive and anxiety symptoms, somatic anxiety, somatic complaints, binge drinking and functional impairment. Boys reported a higher level of problem scores in relation to probable BN. ConclusionsOur findings suggest that bulimia symptoms are prevalent in Russian adolescents and are associated with MHP and functional impairment. Timely recognition of bulimia symptoms and associated MHP is important for early prevention and intervention strategies.

  • Enuresis in young offenders : a study on prevalence and mental health comorbidity
  • 2024
  • Ingår i: Frontiers in Psychiatry. - : Frontiers Media S.A.. - 1664-0640. ; 15
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Enuresis is a common disorder in the school-age period, and is often associated with a variety of behavioral, psychological, and social problems. While early studies suggested an association between enuresis and delinquent behavior, there has been no recent research assessing the prevalence of enuresis and its comorbid psychopathology in young offenders. The aim of this study was to therefore assess the prevalence of enuresis and its associated psychiatric comorbidity in incarcerated young offenders.Methods: The prevalence of past and current enuresis and comorbid psychopathology was assessed using a semi-structured psychiatric interview and self-reports from 366 incarcerated male young offenders [age 14 to 19 years (mean age = 16.4)] from Northern Russia.Results: Seventy-three (20.0%) adolescents reported a previous history of enuresis, and in addition almost 10% of the youth reported current enuresis symptoms. Delinquent youth with enuresis did not significantly differ from other youth in the prevalence of comorbid psychiatric diagnoses when assessed by a clinical diagnostic interview, but had significantly higher levels of self-reported mental health problems, and suicidal ideation and attempts.Conclusion: Problems with enuresis are common among delinquent youth and may be associated with increased mental health problems. Given the potentially increased risk for suicidal thoughts and behavior in young offenders with enuresis, comprehensive mental health screening of those who are detected with this condition should be considered in the juvenile justice system.

  • Bulimia symptoms and anger and aggression among adolescents
  • 2023
  • Ingår i: BMC Public Health. - : BioMed Central (BMC). - 1471-2458. ; 23:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Previous research has indicated that anger and aggression may be elevated in adolescents with a bulimia nervosa (BN) diagnosis. However, as yet, little is known about whether bulimia symptoms are linked to anger and aggression in adolescents in the general population. To address this deficit this study aimed to explore the associations between a clinical level of bulimia symptoms (CLBS) and anger, anger rumination and aggression in community-based adolescents, and determine whether gender is important in this context.METHODS: This study was conducted on a representative sample of youth from northwestern Russia (n = 2613, age 13-17 years old, 59.5% female) using self-report scales. A proxy variable for a CLBS was created using the Eating Disorder Diagnostic Scale. Aggression, anger and anger rumination were assessed by the Trait Anger Scale of the State Trait Anger Expression Inventory, the Anger Rumination Scale, and scales created to assess physically and verbally aggressive behavior. Multivariate analysis of covariance was used to examine the associations between the study variables.RESULTS: A CLBS was more prevalent in girls than in boys (13.4% vs. 3.5%). The association with anger and aggression was stronger in both genders with a CLBS, compared to those adolescents without a CLBS. In the CLBS group, boys as compared to girls scored higher on verbal and physical aggression, anger rumination and social aggression. In both the CLBS and Non-CLBS groups higher anger and aggression scores were associated with increasing age.CONCLUSIONS: Findings suggest that aggression and anger rumination are elevated in adolescents with BN symptoms, and that the associations between anger, aggression and BN symptoms may be stronger in boys. As previous research has indicated that the presence of aggressive behaviors may affect the prognosis of BN and complicate management of the disorder, clinician screening for these behaviors in adolescents with BN symptoms may facilitate the provision of more effective treatment, especially among boys.

  • Community Violence Exposure and School Functioning in Youth : Cross-Country and Gender Perspectives
  • 2021
  • Ingår i: Frontiers in Public Health. - : Frontiers Media S.A.. - 2296-2565. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Many children and adolescents experience violent events which can be associated with negative consequences for their development, mental health, school, and social functioning. However, findings between settings and on the role of gender have been inconsistent. This study aimed to investigate cross-country and gender differences in the relationship between community violence exposure (CVE) and school functioning in a sample of youths from three countries. Methods: A self-report survey was conducted among school students (12-17 years old) in Belgium (Antwerp, N = 4,743), Russia (Arkhangelsk, N = 2,823), and the US (New Haven, N = 4,101). Students were recruited from within classes that were randomly selected from within schools that had themselves been randomly selected (excepting New Haven, where all students were included). CVE was assessed with the Screening Survey of Exposure to Community Violence. School functioning was assessed with four measures: the Perceived Teacher Support scale, Negative Classroom Environment scale, and Academic Motivation and Perception of Safety at School scales. Multivariate Analyses of Covariance were performed to assess differences in the levels of school-related problem behaviors in boys and girls, who reported different degrees of CVE. Results: Participants in all three countries reported a relatively high prevalence of violence exposure (36.2% in Belgium, 39.3% in Russia and 45.2% in the US who witnessed violence), with a higher proportion of girls than boys witnessing violent events (varied from 37.4 to 51.6% between the countries), whereas boys reported more episodes of victimization by violence than girls (varied from 32.3 to 49.9% between the countries). Youths who experienced increased CVE (from no exposure to witnessing to victimization) reported an increase in all school functioning problems in all of the countries and this association was not gender-specific. Conclusions: Our findings suggest that regardless of differences in the level of CVE by country and gender, violence exposure is negatively associated with school functioning across countries. Nonetheless, even though reactions to community violence among adolescents may be expressed in a similar fashion, cross-country differences in social support systems should also be taken into account in order to provide culturally sensitive treatment modalities.

  • Inhalant use in adolescents in northern Russia
  • 2018
  • Ingår i: Social Psychiatry and Psychiatric Epidemiology. - : Springer. - 0933-7954 .- 1433-9285. ; 53:7, s. 709-716
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To determine the prevalence of inhalant use in Russian adolescents and to investigate associated psychosocial problems from a gender perspective. Methods: Data on inhalant use and comorbid psychopathology were collected by means of self-reports from 2892 (42.4% boys) sixth to tenth grade students in public schools in Arkhangelsk, Russia. Multivariate analysis of covariance was used to assess differences in the levels of internalizing and externalizing problems in boys and girls, who were non-users and users of inhalants. Results: The prevalence of inhalant use was 6.1% among boys and 3.4% among girls. Compared with non-users, inhalant users scored significantly higher on internalizing and externalizing problems, functional impairment and lower on academic motivation, with psychopathology increasing with age. While there were no gender differences for internalizing problems, increased levels of externalizing problems in inhalant users were gender-specific (significantly higher in boys). Conclusions: Inhalant use is related to significantly higher levels of comorbid psychopathology in Russian adolescents. Comprehensive, evidence-based prevention and intervention policies are needed to address inhalant use and its harmful effects.

  • Non-Suicidal Self-Injury Among Incarcerated Adolescents : Prevalence, Personality, and Psychiatric Comorbidity
  • 2021
  • Ingår i: Frontiers in Psychiatry. - : Frontiers Media S.A.. - 1664-0640. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Incarcerated adolescents represent a risk group for non-suicidal self-injury (NSSI), but research on this population has been limited and no studies have been conducted in Russia. To address this deficit, this study examined NSSI and the factors associated with it among youth in a juvenile correctional facility in Russia. Methods: NSSI and psychopathology were assessed using a psychiatric interview and self-report questionnaire in 368 incarcerated male adolescents aged 14-19 years (mean age 16.4 years, S.D. 0.9) from Northern Russia. Results: 18.2% (N = 67) of the study participants had a history of NSSI and also had higher rates of anxiety, post-traumatic stress disorder (PTSD), depression, community violence exposure and scored higher on most of the Youth Self-Report problem scales. In addition, 31.3% of the NSSI group reported previous suicidal ideation and had thought about a specific suicide method compared to 12.0% in the No-NSSI group. Adolescents with NSSI also differed significantly from the No-NSSI group on self-directedness (lower) and self-transcendence (higher) personality traits. Conclusion: NSSI is common in incarcerated adolescents in Russia and is associated with extensive psychiatric comorbidity, suicidal ideation and specific personality traits.

  • Bulimia symptoms in Czech youth : prevalence and association with internalizing problems
  • 2020
  • Ingår i: Eating and Weight Disorders. - : Springer. - 1124-4909 .- 1590-1262. ; 25, s. 1543-1552
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Although clinical studies suggest that bulimia symptoms are common in youth, research on the prevalence of such symptoms and of their association with comorbid internalizing problems in the general population has been limited. This study aimed to evaluate the gender-specific prevalence of bulimia symptoms in Czech youth and explored the association between a clinical level of self-reported bulimia symptoms (CLBS) and internalizing problems by gender, controlling for age, socio-economic status and puberty status. Method The study was conducted on a representative national sample of Czech youth (N = 4430, 57.0% female) using self-report scales. Multivariate analysis of covariance (MANCOVA) was used to examine the associations. Results The 3-month CLBS prevalence was higher in girls (11.4%) than in boys (3.8%) and in both genders a CLBS was associated with higher levels of comorbid internalizing problems. Discussion Timely recognition of bulimia symptoms and associated risk factors is important for early prevention and intervention strategies.

    • OBJECTIVE: To test the previously suggested hypothesis that those with comorbid ADHD and Conduct Disorder (CD) diagnoses differ from other antisocially involved youth in terms of higher rates of violent behavior, impulsiveness, and psychopathic traits.METHOD: Three hundred eighty juvenile incarcerated delinquents from Northern Russia were assessed by means of semi-structured psychiatric interview and by student and teacher self-reports.RESULTS: The study has demonstrated higher rates of psychiatric disorders and of comorbidity, as well as more complicated substance abuse and disruptive behaviors in those with combined ADHD-CD diagnosis, as compared with CD only, ADHD only, and no CD no ADHD groups. The results regarding psychopathic traits were inconclusive.CONCLUSION: The group with combined ADHD-CD diagnosis is more severely disturbed, both as concerns psychiatric comorbidity and more severe aggressive and disruptive behaviors. However, there is only limited evidence supporting a higher prevalence of psychopathic traits in this group.

  • Ingår i: European Child and Adolescent Psychiatry. - : SPRINGER. - 1018-8827 .- 1435-165X. ; 27:4, s. 493-500
  • Tidskriftsartikel (refereegranskat)abstract
    • The negative effects of community violence exposure on child and adolescent mental health are well documented and exposure to community violence has been linked both to a number of internalizing and externalizing symptoms. Our aim was, therefore, to investigate cross-cultural and gender differences in the relationship between community violence exposure and substance abuse. A self-report survey was conducted among 10,575, 12-18 year old adolescents in three different countries, Czech Republic (N = 4537), Russia (N = 2377) and US (N = 3661). We found that in all three countries both substance use and problem behavior associated with it increased similarly along with severity of violence exposure and this association was not gender-specific. It was concluded that in spite of the differences in the levels of violence exposure and substance use cross-culturally and by gender, the pattern of their association is neither culturally nor gender bound.

  • Language development of internationally adopted children : Adverse early experiences outweigh the age of acquisition effect
  • 2015
  • Ingår i: Journal of Communication Disorders. - : Elsevier BV. - 0021-9924 .- 1873-7994. ; 57:SI, s. 66-80
  • Tidskriftsartikel (refereegranskat)abstract
    • We compared English language and cognitive skills between internationally adopted children (IA; mean age at adoption=2.24, SD=1.8) and their non-adopted peers from the US reared in biological families (BF) at two time points. We also examined the relationships between outcome measures and age at initial institutionalization, length of institutionalization, and age at adoption. On measures of general language, early literacy, and non-verbal IQ, the IA group performed significantly below their age-peers reared in biological families at both time points, but the group differences disappeared on receptive vocabulary and kindergarten concept knowledge at the second time point. Furthermore, the majority of children reached normative age expectations between 1 and 2 years post-adoption on all standardized measures. Although the age at adoption, age of institutionalization, length of institutionalization, and time in the adoptive family all demonstrated significant correlations with one or more outcome measures, the negative relationship between length of institutionalization and child outcomes remained most robust after controlling for the other variables. Results point to much flexibility and resilience in children's capacity for language acquisition as well as the potential primacy of length of institutionalization in explaining individual variation in IA children's outcomes.LEARNING OUTCOMES: (1) Readers will be able to understand the importance of pre-adoption environment on language and early literacy development in internationally adopted children. (2) Readers will be able to compare the strength of the association between the length of institutionalization and language outcomes with the strength of the association between the latter and the age at adoption. (3) Readers will be able to understand that internationally adopted children are able to reach age expectations on expressive and receptive language measures despite adverse early experiences and a replacement of their first language with an adoptive language.

    • The present study sought to compare 4 groups of age-and gender-matched children-(a) those reared in institutions for children without parental care in Russia; (b) those raised by their biological parents in Russia; (c) those adopted to the United States from Russian institutions; and (d) those born in the United States and raised by their biological parents-on indicators of cognition, language, and early learning. In addition, we aimed to compare the effects of the length of time spent in an institution, the age of initial placement in an institution, the age at adoption, and pre-institutional risk factors (i.e., prenatal substance exposure and prematurity and low birth weight) on the above-mentioned outcomes in the 2 groups of children with institutionalization experiences. Our results confirm previous reports demonstrating negative consequences of institutionalization and substantial ameliorating effects of adoption. They also underscore the complexity of the effects of institutionalization and adoption, showing that they are intertwined with the effects of pre-institutional risk factors.

  • Depressive symptoms and anger and aggression in Russian adolescents
  • 2023

  • Tidskriftsartikel (refereegranskat)abstract
    • Research among adolescents exploring the association between depressive symptoms and aggression has produced inconsistent findings. This study investigated the prevalence of clinically significant (current major depressive episode) and subthreshold depressive symptoms in a general population sample of adolescents from Northern Russia and explored their association with aggression and anger, while controlling for comorbid mental health problems. The sample consisted of 2600 participants, aged 13-17 years (59.5% female; 95.7% ethnic Russian). Symptoms of a current major depressive episode, types of anger and aggression (anger rumination, trait anger, physical, verbal and social aggression) and comorbid problems (posttraumatic stress, alcohol use, anxiety, and hyperactivity/impulsivity) were assessed by means of self-reports. The prevalence of a clinically significant depressive episode in the past month was 3.5%, while for subthreshold depression it was 21.6%. All anger and aggression variables, as well as comorbid problems increased together with increasing levels of depression. The association between overt aggressive behavior and depression was primarily explained by comorbid mental health problems, whereas anger rumination and social aggression had more direct associations with depression, independent of comorbidity. Among adolescents with depression, boys reported higher levels of social and verbal aggression and of anger rumination than girls. The results of this study suggest that interventions aiming to reduce aggressive behavior in adolescents should consider depression and its comorbid conditions.

  • Longitudinal Associations Between Community Violence Exposure and Mental Health Problems in Inner-City Youth : Ethnicity and Gender Perspectives.
  • 2023

  • Tidskriftsartikel (refereegranskat)abstract
    • There is a lack of agreement on whether children and adolescents with different cultural/ethnic backgrounds react to trauma in a similar fashion. This study adds to the existing literature by providing ethnicity and gender perspectives on the longitudinal associations between the degree of community violence exposure (CVE) and mental health problems in U.S. inner-city youth. The study was conducted on a representative sample of predominantly ethnic minority youth (N = 2,794; 54.1% female; age 11-16 years old (M [SD] = 12.77 [1.29]); 60.0% African-American, 26.1% Hispanic American, 13.9% White). Self-reported information was obtained on CVE in year 1 and on mental health problems (depressive symptoms, posttraumatic stress, alcohol use, and conduct problems) in year 1 and year 2. Multivariate analyses of covariance (MANCOVA) were used to compare mental health problems in youth from the three ethnic groups in relation to the different degrees of CVE experienced one year prior, while controlling for their baseline mental health problem levels, age, and socio-economic status. Mental health problems in year 2 increased in a similar fashion in relation to the degree of severity of CVE in year 1 in all three ethnic groups. The interaction effects suggested a gender-specific response to CVE, where girls in the three ethnic groups reported higher levels of depression and posttraumatic stress in relation to the same degree of CVE, as compared to boys. Adolescents from different ethnic backgrounds respond similarly to differing degrees of CVE with an increase in mental health problems over time. In response to a similar degree of exposure, girls tend to experience greater levels of internalizing problems than boys. Timely recognition of traumatic exposure and associated mental health problems is important for early prevention and intervention strategies.

  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to investigate if training with the memory technique Method of Loci (MoL) is feasible for children and adolescents with ADHD. Twelve children (aged 9-17 years) with ADHD participated. Training with MoL was done using a mobile application, memorizing a sequence of 20-80 pictures, intended to be carried out five times per week for 4 weeks. Feasibility was assessed with pre- and post-intervention ratings, and with interviews after the training. Qualitative data were analyzed with content analysis. Those who trained with MoL performed better on memory test and reported fewer ADHD symptoms after completing the training, as compared to their baseline levels. All of these children would recommend the training to peers but the duration of training varied considerably. The participants and their parents reported that the MoL training was easy and fun to use, although lack of motivation, distractions in every-day life, and lack of routines created challenges. We conclude that training with MoL was considered feasible by most of the participants. Future research should try to make the intervention more acceptable by motivating the participants and limiting potential distractions and involving larger study groups and controls to study the efficacy of the training.

  • Tidskriftsartikel (refereegranskat)abstract
    • The objective was two-fold: to examine possible associations between dopamine-related genetic polymorphisms and (1) substance dependence; and (2) self-reported psychiatric disturbances, behavioral problems, and personality. Genotyping of single nucleotide polymorphisms (SNP: s) in COMT, DAT and DRD4 was conducted in 174 Russian male juvenile inmates (14–18 years of age) subdivided into having a diagnosis of substance dependence or not, as assessed by using K-SADS-PL. The inmates completed several self-reports assessing psychiatric symptoms (CPTS-RI, BDI), behavioral problems (YSR), and personality traits (TCI). Results revealed that juveniles meeting the criteria for substance dependence differed significantly from their counterparts in four polymorphisms, namely COMT rs737865, DAT rs6347, DRD4 C_1611535 and DRD4 exon III; and exact binary regression analysis indicated a highly significant association between the DRD4 C_1611535 GG genotype and substance dependence. One-way ANOVA tests further showed this gene polymorphism variant to be significantly associated with higher levels of posttraumatic stress, thought problems, aggressive behavior, and personality traits indicating antisocial personality disturbances, as compared with the other gene polymorphism variants. In conclusion, the results underscore the role of the DRD4 polymorphism C_1611535 GG genotype for substance dependence, and suggest its associations with different self-reported phenotype characteristics.

  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Research on risk factors associated with bulimia nervosa symptoms (BN) in ethnic minorities has been limited. This study adds to the existing literature by providing the ethnicity- and gender-specific prevalence of BN in US inner-city youth and by exploring the longitudinal associations between a clinical level of BN and early risk factors assessed one year previously.METHODS: The study was conducted on a representative sample of predominantly ethnic minority youth (N = 2794; 54.1% female; age 11-16 years old (M(SD) = 12.77(1.29)); 60.0% African-American, 26.1% Hispanic American, 13.9% White). Self-reported information was obtained on BN and early risk factors (e.g., depressive and anxiety symptoms, posttraumatic stress, somatic complaints). Multivariate analysis of covariance was used to examine the longitudinal associations.RESULTS: The 3-month BN prevalence was higher in girls (5.1%) than in boys (2.3%) (ratio 2.22:1). Significant differences in BN rates were found between White and African American students (higher in Whites), whereas Hispanic-Americans did not differ significantly from either group. Individuals with BN had significantly higher levels of early risk factors one year prior.CONCLUSIONS: Timely recognition of BN and associated early risk factors is important for early prevention and intervention strategies.

  • Tidskriftsartikel (refereegranskat)abstract
    • This study evaluated the role of psychiatric morbidity in relation to a history of suicidal behavior, with a particular focus on attention-deficit/hyperactivity disorder (ADHD). Suicidality and psychiatric diagnoses were assessed in 370 incarcerated male juvenile delinquents from Northern Russia using the semi-structured K-SADS-PL psychiatric interview. A lifetime history of suicidal ideation only (24.7 %) and suicidal ideation with suicide attempts (15.7 %) was common. Binary logistic regression analysis was used to assess the role of ADHD and other psychiatric disorders in suicidal ideation and suicide attempts. A history of suicidal ideation and of suicide attempts were associated with higher rates of psychiatric morbidity and with the number of comorbid psychiatric disorders. An ADHD diagnosis was associated with an increased risk for both suicidal ideation and for suicide attempts. The comorbidity of ADHD with drug dependence further increased the risk for suicidal ideation, while ADHD and alcohol dependence comorbidity increased the risk for suicide attempts. Our findings highlight the importance of adequately detecting and treating psychiatric disorders in vulnerable youths, especially when they are comorbid with ADHD.

    • Objective: To examine the impact of posttraumatic stress on the choice of responses to and attribution of intentionality in peer provocation in adolescent boys and girls. Methods: A sample of 2678 adolescents from Northern Russia, aged 13-17 years (59.3% female; 95.7% ethnic Russian) completed self-reports on posttraumatic stress and rated hypothetical peer provocation scenarios that teenagers can encounter in their daily lives. Results: Adolescents with clinically significant levels of posttraumatic stress symptoms (n=184 (6.8%)) reported a different pattern of reactions to peer provocation as compared to all other adolescents. Boys and girls with high levels of posttraumatic symptoms reported that they would be less likely to discuss conflict situations and more likely to react with physical aggression. Compared to their male counterparts, girls with high levels of posttraumatic stress symptoms were more likely to endorse hostile intentions, avoid provocations, and were less likely to endorse verbally aggressive responses. In provocation scenarios that involved physical aggression, girls with high levels of posttraumatic stress symptoms were less likely to endorse verbal aggressive responses and more likely to endorse physically aggressive responses than girls without clinically significant levels of posttraumatic symptoms. Girls with high levels of posttraumatic stress symptoms were also more likely to avoid socially aggressive situations than non-traumatized girls, whereas boys had an opposite pattern. Conclusions: High levels of posttraumatic stress symptoms may play a significant role in the endorsement of aggressive reactions in conflicts with peers and patterns of reactions may be gender-specific. A history of posttraumatic stress should be carefully evaluated in children and adolescents seeking treatment for aggressive behavior.

    • PURPOSE: Comorbid depression is common in adolescents with attention-deficit/hyperactivity disorder (ADHD). As yet, however, little is known about the factors associated with co-occurring depression in this population. To address this research gap, the current study examined the role of community violence exposure in the association between ADHD symptoms and depression.METHODS: Data came from 505 Russian adolescents [mean age 14.37 (SD = 0.96)] who had teacher-reported information on ADHD symptoms that was collected in conjunction with the Social and Health Assessment (SAHA). Adolescent self-reports of witnessing and being a victim of community violence were also obtained while depressive symptoms were self-assessed with an adapted version of the Center for Epidemiologic Studies-Depression Scale (CES-D). Logistic regression analyses were performed to examine associations.RESULTS: In univariable analyses, both witnessing and being a victim of violence were associated with significantly increased odds for depressive symptoms in adolescents with ADHD symptoms compared to non-ADHD adolescents who had not experienced community violence. However, in the multivariable analysis only being a victim of violence continued to be associated with significantly increased odds for depression [odds ratio (OR) 4.67, 95% confidence interval (CI) 1.33-16.35].CONCLUSION: Exposure to community violence may be associated with depression in adolescents with ADHD symptoms. Clinicians should enquire about exposure to community violence in adolescents with ADHD/ADHD symptoms. Early therapeutic interventions to address the effects of violence exposure in adolescents with ADHD may be beneficial for preventing depression in this group.

    • BACKGROUND: Some evidence suggests that in recent years the prevalence of heavy drinking has increased among Russian adolescents. However, as yet, little is known about either heavy alcohol consumption or its relationship with other adolescent health risk behaviours in Russia. The aim of this study therefore was to investigate the association between binge drinking and health risk behaviours among adolescents in Russia.METHODS: Data were drawn from the Social and Health Assessment (SAHA), a survey carried out in Arkhangelsk, Russia in 2003. Information was obtained from a representative sample of 2868 adolescents aged 13-17 regarding the prevalence and frequency of binge drinking (five or more drinks in a row in a couple of hours) and different forms of substance use, risky sexual behaviour and violent behaviour. Logistic regression analysis was used to examine the association between binge drinking and adolescent involvement in various health risk behaviours.RESULTS: Adolescent binge drinking was associated with the occurrence of every type of health risk behaviour - with the sole exception of non-condom use during last sex. In addition, there was a strong association between the number of days on which binge drinking occurred and the prevalence of many health risk behaviours.CONCLUSIONS: Binge drinking is associated with a variety of health risk behaviours among adolescents in Russia. Public health interventions such as reducing the affordability and accessibility of alcohol are now needed to reduce binge drinking and its harmful effects on adolescent well-being.

    • In recent years, there has been an increasing focus on the role of future expectations-the extent to which a future outcome is deemed likely-in the health and well-being of adolescents, with research linking future expectations to outcomes such as an increased likelihood of engaging in risky health behaviors. As yet, however, there has been no research on future expectations and attention deficit/hyperactivity disorder (ADHD) in adolescence. To address this research gap, the current study examined the association between ADHD symptoms/possible ADHD status and future expectations in a school-based sample of adolescents. Data were analyzed from 537 Russian adolescents (aged 12-17) with teacher-reported ADHD symptoms and self-reported future expectations. Logistic regression analysis was used to examine associations. In fully adjusted analyses, inattention symptoms/possible ADHD inattentive status was associated with lower future educational expectations, while a possible ADHD hyperactivity status was associated with increased odds for negative future expectations relating to work, family and succeeding in what is most important. The findings of this study suggest that greater ADHD symptoms/possible ADHD status in adolescence may be linked to an increased risk for negative future expectations across a variety of different life domains.

    • Background:There has been little research on the association of attention-deficit/hyperactivity disorder (ADHD) with co-occurring physical diseases. The aim of this study was to examine the association between possible ADHD and physical multimorbidity (i.e. = 2 physical diseases) among adults in the English general population.Methods:Data were analyzed from 7274 individuals aged = 18 years that came from the Adult Psychiatric Morbidity Survey 2007. ADHD symptoms were assessed with the Adult Self-Report Scale (ASRS) Screener. Information was also obtained on 20 self-reported doctor/other health professional diagnosed physical health conditions present in the past 12 months. Multivariable logistic regression and mediation analyses were conducted to assess the associations.Results:There was a monotonic relation between the number of physical diseases and possible ADHD (ASRS score = 14). Compared to those with no diseases, individuals with = 5 diseases had over 3 times higher odds for possible ADHD (odds ratio [OR]: 3.30, 95% confidence interval [CI]: 2.48–4.37). This association was observed in all age groups. Stressful life events (% mediated 10.3–24.3%), disordered eating (6.8%), depression (12.8%), and anxiety (24.8%) were significant mediators in the association between possible ADHD and physical multimorbidity.Conclusion:Adults that screen positive for ADHD are at an increased risk for multimorbidity and several factors are important in this association. As many adults with ADHD remain undiagnosed, the results of this study highlight the importance of detecting adult ADHD as it may confer an increased risk for poorer health outcomes, including physical multimorbidity.

    • A large body of research has shown that exposure to community violence is common for many children across the world. However, less is known about exposure in particular subgroups such as those children with developmental disorders. To address this research gap, the aim of this study was to examine community violence exposure (CVE) in adolescents with attention-deficit/hyperactivity disorder (ADHD) symptoms and the role of gender in this association. Data were analyzed from 2,782 adolescents aged 13 to 17 years from Arkhangelsk, Russia that were collected during the Social and Health Assessment (SAHA). ADHD status was assessed with the hyperactivity/inattention scale of the Strengths and Difficulties Questionnaire (SDQ). Information was obtained on past-year witnessing and violence victimization in the community. Results showed that CVE was more prevalent in children with ADHD symptoms. Specifically, 75.1% of children with ADHD symptoms had been exposed to any violence versus 62.3% in the non-ADHD group (χ2 = 18.65, p <.001). Multivariate analyses of covariance (MANCOVAs) revealed that CVE was significantly higher for adolescents with ADHD symptoms for both witnessing and victimization, while exposure was significantly higher for ADHD boys compared with girls. The findings of this study suggest that CVE may be elevated in adolescents with higher ADHD symptoms. Given that CVE has been associated with a variety of negative social and psychological outcomes in typically developing children, an important task for future research is to determine what factors are associated with CVE in adolescents with ADHD symptoms including those relating to such phenomena as comorbid psychopathology, the family, and peer relations, so that interventions can be designed and implemented to reduce CVE and its detrimental effects in this population.

    • Abstract Despite an increasing focus on the role of mood and emotions in attention-deficit/hyperactivity disorder (ADHD), as yet, there has been comparatively little research on positive emotions. To address this research gap, the current study examined the association between ADHD symptoms and happiness using data from the 2007 Adult Psychiatric Morbidity Survey. The analytic sample comprised 7274 adults aged 18 and above residing in private households in England. Information was collected on ADHD symptoms using the Adult ADHD Self-Report Scale (ASRS) Screener, while happiness was assessed with a single (3-point) measure. Multivariable ordinal logistic regression analysis and a mediation analysis were performed to examine associations. Greater ADHD symptom severity was associated with higher odds for feeling less happy. Emotional instability (percentage mediated 37.1%), anxiety disorder (35.6%) and depression (29.9%) were all important mediators of the association between ADHD and happiness. Given that happiness has been linked to a number of beneficial outcomes, the results of this study highlight the importance of diagnosing ADHD in adults and also of screening for and treating any comorbid psychiatric disorders in these individuals.

    • Background: Research on the association between adult attention-deficit/hyperactivity disorder (ADHD) and loneliness is scarce even though factors which have been previously linked to loneliness, such as divorce and poorer mental health may be more prevalent among adults with ADHD. This study investigated the relation between ADHD symptoms/symptom severity and loneliness in the general adult population. Methods: Data from the Adult Psychiatric Morbidity Survey 2007 (N = 7403, aged >16 years) were analyzed. ADHD symptoms and common mental disorders (CMDs) were assessed with the Adult ADHD Self-Report Scale (ASRS) Screener and the Clinical Interview Schedule Revised, respectively. Loneliness was measured with a question from the Social Functioning Questionnaire. Multivariable logistic regression analysis was used to examine the associations. Results: In the fully adjusted model, an ASRS score >14 was strongly associated with loneliness (OR= 2.48 95%CI = 1.83-336). ADHD symptom severity was related to loneliness in a dose-response fashion. Over one-third of the association between ADHD symptoms and loneliness was explained by CMDs. Conclusions: Adults with more ADHD symptoms are at an increased risk of feeling lonely. Future research should determine how ADHD symptoms are linked to loneliness and if loneliness is affectihg well-being.

    • Background: The experience of discrimination is common in individuals with mental health problems and has been associated with a range of negative outcomes. As yet, however, there has been an absence of research on this phenomenon in adults with attention-deficit/hyperactivity disorder (ADHD). The current study examined the association between ADHD symptoms and mental health discrimination in the general adult population. Methods: The analytic sample comprised 7274 individuals aged 18 and above residing in private households in England that were drawn from the Adult Psychiatric Morbidity Survey, 2007. Information on ADHD was obtained with the Adult ADHD Self-Report Scale (ASRS) Screener. A single-item question was used to assess mental health discrimination experienced in the previous 12 months. Logistic regression analysis was used to examine associations. Results: The prevalence of discrimination increased as ADHD symptoms increased but was especially elevated in those with the most severe ADHD symptoms (ASRS score 18–24). In a multivariable logistic regression analysis that was adjusted for a variety of covariates including common mental disorders, ADHD symptoms (ASRS ≥ 14) were associated with almost 3 times higher odds for experiencing mental health discrimination (odds ratio: 2.81, 95% confidence interval: 1.49–5.31). Conclusion: ADHD symptoms are associated with higher odds for experiencing mental health discrimination and this association is especially elevated in those with the most severe ADHD symptoms. Interventions to inform the general public about ADHD may be important for reducing the stigma and discrimination associated with this disorder in adults.

    • OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) symptoms have been linked to suicidal behavior. However, little is known about the mechanisms involved in this association. This study examined ADHD symptoms and suicidal ideation during the COVID-19 pandemic and the role of self-perceived stress in this association.METHOD: Data were analyzed from an online sample of 1,452 Japanese individuals aged 18 to 89 obtained in February 2021. Information was collected on past-year suicidal ideation. ADHD symptoms were assessed with the Adult ADHD Self-Report Scale (ASRS) Screener while stress was measured with the Perceived Stress Scale (PSS-14). Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ-9), while the Generalized Anxiety Disorder scale (GAD-7) was used to assess anxiety symptoms. Logistic regression was used to examine associations.RESULTS: Fifty-one (3.5%) individuals had ADHD symptoms, while more than one in ten (11.7%) of the respondents reported past-year suicidal ideation. In an analysis adjusted for sociodemographic factors, ADHD symptoms were associated with eight times higher odds for past-year suicidal ideation. However, adjusting the analysis for mental health variables (anxiety and depressive symptoms) attenuated the association which became non-significant (odds ratio [OR]: 1.96, 95% confidence interval [CI]: 0.92-4.18). In contrast, in an analysis adjusted for mental health, individuals with ADHD symptoms and stress had significantly higher odds for suicidal ideation (OR: 3.72, 95%CI: 1.43-9.67) whereas, ADHD symptoms without stress were not linked to suicidal ideation (OR: 1.25, 95%CI: 0.38-4.18).CONCLUSIONS: Self-perceived stress is important in the association between ADHD symptoms and suicidal ideation among individuals in Japan during the COVID-19 pandemic. Detecting and managing stress and its effects in individuals with ADHD/ADHD symptoms should be a therapeutic focus for improving health-related outcomes in this population both during the COVID-19 pandemic and beyond.

  • Binge drinking among adolescents in Russia : Prevalence, risk and protective factors
  • 2013
  • Ingår i: Addictive Behaviours. - : Elsevier BV. - 0306-4603 .- 1873-6327. ; 38:4, s. 1988-1995

    • Despite evidence that alcohol misuse has been having an increasingly detrimental effect on adolescent wellbeing in Russia in recent years this phenomenon has been little researched. Using data from 2112 children from the Arkhangelsk Social and Health Assessment (SAHA) 2003, this study examined which factors acted as 'risk' or 'protective' factors for adolescent binge drinking within three domains we termed the 'family environment', the 'alcohol environment' and 'deviant behaviour'. The results showed that in the presence of comparatively moderate levels of binge drinking among both boys and girls, being able to access alcohol easily, being unaware of the risks of binge drinking and having peers who consumed alcohol increased the risk of adolescent binge drinking - as did playing truant, smoking and marijuana use, while parental warmth was protective against binge drinking for girls. Our finding that risk and protective factors occur across domains suggests that any interventions targeted against adolescent binge drinking may need to simultaneously focus on risk behaviours in different domains, while at the same time, broader social policy should act to limit the availability of alcohol to adolescents in Russia more generally.

    • Objectives: To determine the factors associated with weapon carrying in school among Czech, Russian, and US adolescents. Methods: Logistic regression was used to analyze data drawn from the Social and Health Assessment (SAHA). Results: Violent behavior (perpetration / victimization) was linked to adolescent weapon carrying in all countries. Substance use was associated with weapon carrying among boys in all countries. Greater parental warmth reduced the odds for weapon carrying among Czech and Russian adolescents. Associating with delinquent peers was important for weapon carrying only among US adolescents. Conclusions: Factors associated with weapon carrying in school vary among countries although violent behavior and substance use may be associated with weapon carrying across countries.

  • Loneliness and health risk behaviours among Russian and US adolescents : a cross-sectional study
  • 2014
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 14
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: For some adolescents feeling lonely can be a protracted and painful experience. It has been suggested that engaging in health risk behaviours such as substance use and sexual behaviour may be a way of coping with the distress arising from loneliness during adolescence. However, the association between loneliness and health risk behaviour has been little studied to date. To address this research gap, the current study examined this relation among Russian and U.S. adolescents. Methods: Data were used from the Social and Health Assessment (SAHA), a school-based survey conducted in 2003. A total of 1995 Russian and 2050 U.S. students aged 13-15 years old were included in the analysis. Logistic regression was used to examine the association between loneliness and substance use, sexual risk behaviour, and violence. Results: After adjusting for demographic characteristics and depressive symptoms, loneliness was associated with a significantly increased risk of adolescent substance use in both Russia and the United States. Lonely Russian girls were significantly more likely to have used marijuana (odds ratio [OR]: 2.28; confidence interval [CI]: 1.17-4.45), while lonely Russian boys had higher odds for past 30-day smoking (OR, 1.87; CI, 1.08-3.24). In the U.S. loneliness was associated with the lifetime use of illicit drugs (excepting marijuana) among boys (OR, 3.09; CI, 1.41-6.77) and with lifetime marijuana use (OR, 1.79; CI, 1.26-2.55), past 30-day alcohol consumption (OR, 1.80; CI, 1.18-2.75) and past 30-day binge drinking (OR, 2.40; CI, 1.56-3.70) among girls. The only relation between loneliness and sexual risk behaviour was among Russian girls, where loneliness was associated with significantly higher odds for ever having been pregnant (OR, 1.69; CI: 1.12-2.54). Loneliness was not associated with violent behaviour among boys or girls in either country. Conclusion: Loneliness is associated with adolescent health risk behaviour among boys and girls in both Russia and the United States. Further research is now needed in both settings using quantitative and qualitative methods to better understand the association between loneliness and health risk behaviours so that effective interventions can be designed and implemented to mitigate loneliness and its effects on adolescent well-being.

  • Loneliness and posttraumatic stress in U.S. adolescents : A longitudinal study
  • 2024
  • Ingår i: Journal of Affective Disorders. - : Elsevier. - 0165-0327 .- 1573-2517. ; 361, s. 113-119
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Loneliness and posttraumatic stress (PTS) are common in adolescence. However, there has been little longitudinal research on their association. To address this deficit, this study examined the longitudinal association between these phenomena in a sample of U.S. school students while also exploring if gender was important in this context.METHODS: Data were analysed from 2807 adolescents (52.1 % female; age at baseline 11-16 years (M = 12.79)) who were followed over a one-year period. Information was obtained on loneliness in year 1 using a single-item question, while PTS was assessed with the self-report Child Post-Traumatic Stress - Reaction Index (CPTS-RI). A full path analysis was performed to assess the across time associations.RESULTS: Almost one-third of the students reported some degree of loneliness while most students had 'mild' PTS. In the path analysis, when controlling for baseline PTS and other covariates, loneliness in year 1 was significantly associated with PTS in year 2 (β = 0.06, 95%CI: 0.02, 0.09). Similarly, PTS in year 1 was significantly associated with loneliness in year 2 (β = 0.19, 95%CI: 0.15, 0.23). An interaction analysis further showed that loneliness was higher in girls with PTS than in their male counterparts.LIMITATIONS: The use of a single-item measure to assess loneliness that used the word 'lonely' may have resulted in underreporting.CONCLUSION: Loneliness and PTS are bidirectionally associated in adolescence. Efforts to reduce loneliness in adolescence may help in combatting PTS, while clinicians should intervene to address loneliness if detected in adolescents with PTS.

  • Peer victimisation and its association with psychological and somatic health problems among adolescents in northern Russia
  • 2013
  • Ingår i: Child and Adolescent Psychiatry and Mental Health. - : Springer Science and Business Media LLC. - 1753-2000. ; 7:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: A growing body of evidence from countries around the world suggests that school-based peer victimisation is associated with worse health outcomes among adolescents. So far, however, there has been little systematic research on this phenomenon in the countries of the former Soviet Union. The aim of this study was to examine the relation between peer victimisation at school and a range of different psychological and somatic health problems among Russian adolescents.METHODS: This study used data from the Social and Health Assessment (SAHA) - a cross-sectional survey undertaken in Arkhangelsk, Russia in 2003. Information was collected from 2892 adolescents aged 12-17 about their experiences of school-based peer victimisation and on a variety of psychological and somatic health conditions. Logistic regression analysis was used to examine the association between victimisation and health.RESULTS: Peer victimisation in school was commonplace: 22.1% of the students reported that they had experienced frequent victimisation in the current school year (girls - 17.6%; boys - 28.5%). There was a strong relationship between experiencing victimisation and reporting worse health among both boys and girls with more victimisation associated with an increased risk of experiencing worse health. Girls in the highest victimisation category had odds ratios ranging between 1.90 (problems with eyes) and 5.26 (aches/pains) for experiencing somatic complaints when compared to their non-victimised counterparts, while the corresponding figures for boys were 2.04 (headaches) and 4.36 (aches/pains). Girls and boys who had the highest victimisation scores were also 2.42 (girls) and 3.33 (boys) times more likely to report symptoms of anxiety, over 5 times more likely to suffer from posttraumatic stress and over 6 times more likely to experience depressive symptoms.CONCLUSION: Peer victimisation at school has a strong association with poor health outcomes among Russian adolescents. Effective school-based interventions are now urgently needed to counter the negative effects of victimisation on adolescents' health in Russia.

  • Ingår i: Scientific Reports. - : Springer Nature. - 2045-2322. ; 13:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Poorer mental health is linked to a lower likelihood of voting in elections. However, little is known about this association in non-Western settings. This study examined the association between psychological distress and voting in nine countries of the former Soviet Union (FSU). Data were analysed from 18,000 respondents aged ≥ 18 in Armenia, Azerbaijan, Belarus, Georgia, Moldova, Kazakhstan, Kyrgyzstan, Russia and Ukraine collected during the Health in Times of Transition (HITT) survey in 2010/11. Information was collected on previous voting behaviour and future voting intentions. Psychological distress was assessed with a 12-item scale. In pooled multivariable logistic regression analyses psychological distress was significantly associated with ‘never voting’ (not having voted previously or intending to vote in future) and ‘past voting only’ (having voted previously but not intending to vote in future). In stratified analyses psychological distress was linked to never voting in women and working-age adults. The significant association between psychological distress and voting was observed only in hybrid political regimes. Psychological distress is associated with a reduced likelihood of voting in FSU countries especially among women, working-age adults and those in hybrid political regimes.

  • Somatic symptoms and internalizing problems in urban youth : a cross-cultural comparison of Czech and Russian adolescents.
  • 2018
  • Ingår i: European Journal of Public Health. - : Oxford University Press. - 1101-1262 .- 1464-360X. ; 28:3, s. 480-484
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Although the association between somatic complaints and internalizing problems (anxiety, somatic anxiety and depression) is well established, it remains unclear whether the pattern of this relationship differs by gender and in different cultures. The aim of this study was to examine cross-cultural and gender-specific differences in the association between somatic complaints and internalizing problems in youth from the Czech Republic and Russia.Methods: The Social and Health Assessment, a self-report survey, was completed by representative community samples of adolescents, age 12-17 years, from the Czech Republic (N = 4770) and Russia (N = 2728).Results: A strong association was observed between somatic complaints and internalizing psychopathology. Although the levels of internalizing problems differed by country and gender, they increased together with and largely in a similar way to somatic complaints for boys and girls in both countries.Conclusion: The association between somatic symptoms and internalizing problems seems to be similar for boys and girls across cultures.

  • Inhalant Use and Mental Health Problems in Russian Juvenile Delinquents
  • 2017
  • Ingår i: Substance Use & Misuse. - : Taylor & Francis. - 1082-6084 .- 1532-2491. ; 52:12, s. 1616-1623
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Inhalant use by children and adolescents has been linked to an increased risk of multiple drug use, mental health problems and antisocial behavior.OBJECTIVES: The purpose of this study was to examine the association between the frequency of inhalant use and psychiatric diagnoses among incarcerated delinquent youths in Russia.METHODS: A total of 370 incarcerated delinquents from a juvenile correction center in Northern Russia were assessed by means of a semi-structured psychiatric interview and by self-reports.RESULTS: Compared to non-users (N = 266), inhalant users (N = 104) reported higher rates of PTSD, early onset conduct disorder, ADHD, alcohol abuse and dependence, as well as higher levels of antisocial behavior, impulsiveness and more psychopathic traits. Frequent inhalant users also reported the highest rates of co-occurring psychopathology.CONCLUSIONS: Our findings suggest that inhalant use in delinquents is frequent and may require additional clinical measures to address the issue of psychiatric comorbidity.
