  • 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.

  • 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.

  • 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.

  • 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.

  • Sources of Heterogeneity in Developmental Outcomes of Children With Past and Current Experiences of Institutionalization in Russia : A Four-Group Comparison
  • 2017
  • Ingår i: American Journal of Orthopsychiatry. - : AMER PSYCHOLOGICAL ASSOC. - 0002-9432 .- 1939-0025. ; 87:3, s. 242-255
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Dopamine-related receptors, substance dependence, behavioral problems and personality among juvenile delinquents
  • 2021
  • Ingår i: Personality and Individual Differences. - : Elsevier BV. - 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.

  • 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.

  • Attention deficit/hyperactivity disorder and future expectations in Russian adolescents
  • 2019
  • Ingår i: ADHD Attention Deficit and Hyperactivity Disorders. - : Springer. - 1866-6116 .- 1866-6647. ; 11:3, s. 279-287
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • 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.
