  • 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 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Attention-Deficit/Hyperactivity Disorder Symptoms and Community Violence Exposure in Russian Adolescents
  • 2021
  • Ingår i: Journal of Interpersonal Violence. - : Sage Publications. - 0886-2605 .- 1552-6518. ; 36:17-18, s. NP9738-NP9756
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.
