Violence Exposure, Posttraumatic Stress, and Personality in Juvenile Delinquents

OBJECTIVE To assess posttraumatic stress and its relationship to comorbid psychopathology, violence exposure, and personality traits in Russian male juvenile delinquents. METHOD Posttraumatic stress and comorbid psychopathology were assessed by a semistructured psychiatric interview (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version) in 370 delinquent youths during winter-spring of 1999. In addition, violence exposure, personality, and psychopathology were assessed by self-reports. RESULTS Most delinquents reported some degree of posttraumatic stress: 156 subjects (42%) fulfilled partial criteria and 87 (25%) fulfilled full DSM-IV criteria for posttraumatic stress disorder (PTSD). Violence-related experiences (witnessing and victimization) were the most common types of trauma. Higher levels of posttraumatic stress were accompanied by higher rates of comorbid psychopathology, with the most striking differences occurring between the groups with full versus partial PTSD criteria. Violence exposure was related to temperamental behavior activation (novelty seeking), whereas PTSD symptom scores were predominantly related to behavior inhibition and poor coping (high harm avoidance and low self-directedness). CONCLUSIONS Similar to findings from American samples, Russian juvenile delinquents represent a severely traumatized population, mainly due to high levels of violence exposure. Those with full PTSD are the most severely traumatized and have highest rates of psychopathology, as compared to those with no or partial PTSD, and they require the most clinical attention and rehabilitation. Both exposure to violence and levels of posttraumatic stress are related to personality traits, which influence degree of exposure and individual perception of stress. The latter should be considered in individualized approaches to rehabilitation.

Adolescents in transition : school and family characteristics in the development of violent behaviors entering high school.

Adolescents are vulnerable to becoming involved in problematic behaviors, disengaging academically, and dropping out of school. This study was designed to evaluate the protective role of self-perceived school attachment and family involvement on the development of these negative behaviors during adolescence. The Social and Health Assessment (SAHA) survey was conducted among 652 predominantly minority, inner-city adolescents during their transition from middle to high school in order to examine school attachment, perceived teacher support, parental control, and exposure to community violence as predictors of engagement in violent activities, development of aggressive beliefs, perception of school climate, and academic motivation one year later. Family and school factors appeared to be differentially associated with the negative outcomes. School attachment was associated with lower levels of violent delinquency and aggressive beliefs, as well as with academic motivation. Perceived teacher support was associated with positive perceptions of school climate and with academic motivation. Parental control was associated with lower levels of violent activity and with higher levels of academic motivation. Violence exposure was related to violent delinquency and negative perception of school climate. School attachment, teacher support, parental control, and violence exposure must all be incorporated into school reform efforts intended to break the inner city cycle of violence.

Risk Factors for Violent Offending in Autism Spectrum Disorder A National Study of Hospitalized Individuals

Little is known about risk factors for violence among individuals with autism spectrum disorder (ASD). This study uses data from Swedish longitudinal registers for all 422 individuals hospitalized with autistic disorder or Asperger syndrome during 1988-2000 and compares those committing violent or sexual offenses with those who did not. Thirty-one individuals with ASD (7%) were convicted of violent nonsexual crimes and two of sexual offenses. Violent individuals with ASD are more often male and diagnosed with Asperger syndrome rather than autistic disorder. Furthermore, comorbid psychotic and substance use disorders are associated with violent offending. We conclude that violent offending in ASD is related to similar co-occurring psychopathology as previously found among violent individuals without ASD. Although this study does not answer whether ASDs are associated with increased risk of violent offending compared with the general population, careful risk assessment and management may be indicated for some individuals with Asperger syndrome.

Association Between Polymorphisms in the Dopamine Transporter Gene and Depression Evidence for a Gene-Environment Interaction in a Sample of Juvenile Detainees

Previous research has generated examples of how genetic and environmental factors can interact to create risk for psychopathology. Using a gene-by-environment (G X E) interaction design, we tested whether three polymorphisms in the dopamine transporter gene (DAT1, also referred to as SLC6A3, located at 5p15.33) interacted with maternal parenting style to predict first-onset episodes of depression. Participants were male adolescents (N = 176) recruited from a juvenile detention center in northern Russia. As hypothesized, one of the polymorphisms (rs40184) moderated the effect of perceived maternal rejection on the onset of major depressive disorder, as well as on suicidal ideation. Further, this G X E interaction was specific to depression; it did not predict clinically significant anxiety. These results highlight the need for further research investigating the moderating effects of dopaminergic genes on depression.

Suicidal ideations and attempts in juvenile delinquents

BACKGROUND Suicidality among adolescents is a common focus of clinical attention. In spite of links to disruptive behaviors and other types of psychopathology, it is not clear whether other factors commonly associated with suicide, such as personality and parenting, predict suicidality over and above psychopathology. The purpose of the present study was to assess suicidal ideations and attempts and their relationship to psychopathology, violence exposure, personality traits and parental rearing in Russian male juvenile delinquents with conduct disorder (CD). METHOD Suicidality and psychopathology were assessed using a semi-structured psychiatric interview in 271 incarcerated male juvenile delinquents diagnosed with CD. Violence exposure, personality characteristics and perceived parental rearing were assessed via self-reports. RESULTS Thirty-four percent of those diagnosed with CD (92 subjects) reported a lifetime history of either suicidal thoughts or attempts. Suicidal ideators and attempters did not differ significantly on any variable of interest, but both reported significantly higher rates of psychopathology and violence exposure than the non-suicidal group, as well as higher levels of harm avoidance, lower self-directedness, and higher rates of perceived negative parental rearing. Finally, even when controlling for the relationship with psychopathology, personality and perceived parental rearing factors showed significant associations with suicidality. CONCLUSIONS Juvenile delinquents with CD have high rates of suicidal ideations and attempts, related to a wide spectrum of psychopathology and specific personality traits. These findings suggest that a combination of intrinsic and extrinsic factors create vulnerability to stressors, which under the influence of situational factors (e.g., repeated traumatization) may lead to suicidal thoughts and acts. Factors potentially contributing to vulnerability for suicidality should be identified when planning prevention and rehabilitation efforts for troubled youth.

Suicidal behavior and violence in male adolescents: a school-based study.

OBJECTIVE To investigate characteristics of suicidal and violent behavior in a community school sample of adolescents. METHOD Self-report questionnaires were administered to 794 male students (aged 12-18 years) from Antwerp, Belgium. Subjects were classified into four groups: a suicidal-only (n = 40; suicidal ideation and/or self-harming behavior), a violent-only (n = 142), a suicidal-violent (n = 21), and a control group (n = 591). RESULTS Compared with controls, higher levels of internalizing problems, risk-taking behavior (substance use, diminished perception of risk, sensation seeking), and aggression were found in the comparison groups. The suicidal-violent group had the highest levels of depression, somatization, overt and covert aggression, and risk-taking behavior. Compared with the suicidal-only group, the violent-only group had less depression, anxiety, and covert aggression, but higher levels of overt aggression, sensation seeking, diminished perception of risk, and marijuana use. CONCLUSIONS Although adolescent suicidal and violent behavior are both related to internalizing problems, aggression, and risk-taking behavior, marked differences in severity and nature exist in these relationships. Differentiation of suicidal youths based on the presence or absence of violent behavior may add to our understanding of suicidal phenomena and may thus have important clinical consequences.

Interrelations Between Temperament, Character, and Parental Rearing in Male Delinquent Adolescents in Northern Russia

A comparison between 192 male delinquent adolescents and 121 controls from Northern Russia using the Temperament and Character Inventory (TCI) and Own Memories of Parental Rearing (EMBU) questionnaire on perceived parental rearing showed significant differences. The delinquent group had a higher level of Novelty Seeking, Harm Avoidance, and Self-transcendence, and also scored lower on Self-directedness. Delinquents who committed nonviolent crimes (thefts) appeared to have a higher level of Harm Avoidance compared with those who committed violent crimes (hooliganism, robbery, rape, and murder). As concerns perceived parental rearing practices, delinquents experienced more parental rejection and overprotection. Most of the personality dimensions were found to be highly correlated with the level of parental emotional warmth. Furthermore, both temperament traits and maternal rearing practices predicted the development of character dimensions. Findings are discussed in light of the interactive nature of parent-child relationships and of character development.

Loneliness and health risk behaviours among Russian and U.S. adolescents: a cross-sectional study

BackgroundFor 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.MethodsData 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.ResultsAfter 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.ConclusionLoneliness 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.

The Strengths and Difficulties Questionnaire: The Self-Report Version in American Urban and Suburban Youth.

This study examined the factor structure of the Strengths and Difficulties Questionnaire (SDQ) in urban inner-city and suburban general population samples of American youth. The SDQ was administered to 4,661 predominantly minority urban youth (mean age = 13.0 years, SD = 2.02) and 937 predominantly Caucasian suburban youth (mean age = 14.0 years, SD = 1.56). The authors examined SDQ factor structure using structural equation modeling techniques. The fit for the 5-factor models in both samples was very good (comparative fit index = .96-.97). However, the factor loadings and, correspondingly, the scale reliabilities for most of the SDQ scales (except for Emotional Problems) were low, which suggests poor specificity of the items. Subsequent exploratory and confirmatory factor analyses suggested that a 3-factor structure had a comparable model fit and better internal consistency of the scales. The study concluded that, although the SDQ scales do conform reasonably well to a 5-factor model, the scales are unsatisfactory in other respects and that, in its present form, the instrument has inadequate psychometric characteristics. Future research is needed for further scale development.

Psychosocial predictors of sexual initiation and high-risk sexual behaviors in early adolescence

BackgroundThis longitudinal study examined psychosocial factors associated with risky sexual behavior in early adolescence.MethodsData were collected through a self-report survey, the Social and Health Assessment (SAHA), which was administered in three waves between 2001 and 2003 to a cohort of incoming sixth grade students in the public school system (149 classes at 17 middle and high schools, N = 1,175) of a small northeastern city in the United States.We first examined whether internalizing and externalizing problems in sixth grade, and the rate of change in these factors during middle school, were predictive of sexual initiation two years later, when most of the sample was in eighth grade. We then assessed whether internalizing and externalizing problems in sixth grade, and the rate of change in these factors during middle school, were predictive of engaging in high risk sexual behavior over the subsequent two years.ResultsExternalizing factors are more predictive of sexual risk in early adolescence than are internalizing factors. Specifically, substance use and violent delinquency over the course of middle school were associated with higher, while anxiety with lower, sexual initiation rates during middle school. Additionally, increased substance use over the course of middle school was associated with greater likelihood of engaging in high risk sexual behavior.ConclusionBy identifying particular psychosocial risk factors among young adolescents, the findings of this study have implications for designing multi-dimensional programs aimed at preventing health-compromising sexual behavior among young teens.
