  • Risky sexual behaviour among Russian adolescents : association with internalizing and externalizing symptoms
  • 2021
  • Ingår i: Child and Adolescent Psychiatry and Mental Health. - : Springer Nature. - 1753-2000 .- 1753-2000. ; 15:1
  • 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 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

    • 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.

  • 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.

  • Prevalence and early risk factors for bulimia nervosa symptoms in inner-city youth : gender and ethnicity perspectives
  • 2021
  • Ingår i: Journal of Eating Disorders. - : Springer Nature. - 2050-2974. ; 9:1
  • 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.

  • 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.

  • 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 .- 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.

  • Dopamine-related receptors, substance dependence, behavioral problems and personality among juvenile delinquents
  • 2021
  • Ingår i: Personality and Individual Differences. - : PERGAMON-ELSEVIER SCIENCE LTD. - 0191-8869 .- 1873-3549. ; 169
  • 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.

  • Suicidal Behavior in Juvenile Delinquents : The Role of ADHD and Other Comorbid Psychiatric Disorders
  • 2017
  • Ingår i: Child Psychiatry and Human Development. - : Springer. - 0009-398X .- 1573-3327. ; 48:5, s. 691-698
  • 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.

  • ADHD and depressive symptoms in adolescents : the role of community violence exposure
  • 2019
  • Ingår i: Social Psychiatry and Psychiatric Epidemiology. - : Springer. - 0933-7954 .- 1433-9285. ; 54:6, s. 683-691
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
