  • Psychopathy and violence in juvenile delinquents : What are the associated factors?
  • 2008
  • Ingår i: International Journal of Law and Psychiatry. - 0160-2527 .- 1873-6386. ; 31:3, s. 272-279

    • The purpose of the present study was a) to examine the discriminative power of the Antisocial Process Screening Device (APSD), aggressive traits, impulsiveness, antisocial attitudes and alcohol-related problems between subgroups of Russian juvenile delinquents (n = 175) with low versus high levels of violent behavior; and b) to compare the predictive value of these variables in two subgroups defined by higher versus lower levels of psychopathic traits. Results demonstrated that the APSD score, traits of physical aggression and alcohol-related problems were able to discriminate between groups with various levels of violence. Furthermore, the level of violence was the only variant factor when comparing levels of psychopathy. Finally, different sets of predictors emerged for the group with higher versus lower psychopathy scores. The results are discussed in relation to specific features of psychopathy and environmental factors in general and the use of alcohol in particular.

  • Poor school bonding and delinquency over time : Bidirectional effects and sex differences
  • 2011
  • Ingår i: Journal of Adolescence. - : Elsevier. - 0140-1971 .- 1095-9254. ; 34:1, s. 1-9
  • Tidskriftsartikel (refereegranskat)abstract
    • The association between poor school bonding and delinquency has only been partly addressed in earlier research. Using a longitudinal design, the objective of our study was to investigate possible bidirectional effects and sex differences between adolescents’ experienced school bonding and self-rated delinquency over time. A total of 788 adolescents (353 boys and 435 girls) were investigated by questionnaire at age 14 and 16. Poor school attachment and commitment as well as poor teacher attachment were found to be stronger determinants of delinquency for males than for females. Delinquency predicted poor school commitment for both boys and girls, and poor school attachment for girls, thus indicating bidirectional effects over time and sex differences in some of the bidirectional effects. The study concludes that the delinquency propensity of adolescent boys may be affected by all school bonding dimensions, whereas for girls it is their relationship with their teachers that is of significance.

  • Stressors, anxiety, acculturation and adjustment among international and North American students
  • 2008
  • Ingår i: International Journal of Intercultural Relations. - 0147-1767 .- 1873-7552. ; 32:3, s. 244-259
  • Tidskriftsartikel (refereegranskat)abstract
    • The acculturation process generally contributes greatly to stress and anxiety levels among international students. The objectives of the present study were: (1) to see whether international students experience more anxiety, irritability, and stress from being apart from family and friends, pressure from school, difficulties with language, work and finances than students with permanent US residency, and (2) to investigate the same stressors in groups within the international student population. Surveys were distributed to 246 students aged 17-51 at an ethnically diverse community college in Southern California, US. Analysis of variance was conducted to investigate group differences between students: permanent US residents vs. international students, and, permanent US residents vs. European and Asian students, respectively. No significant differences were found between international students and students with permanent US residency. However, when the international student population was sub-grouped by above cultural regions a different pattern emerged. Difficulties of not being able to work and of socially related problems were perceived as more severe for the European and the Asian groups, while finance problems were hard for all three groups. The variable of language difficulties was harder for Asian students, while that of stress of being apart from family was harder for students from Europe. Findings are not only congruent with prior research results on international students but also demonstrate that international students with culturally diverse needs should not be considered as one homogenous group. It is suggested that educational systems need to properly adapt in order to accommodate international students' unique cultural needs.

  • Antisocial process screening device : Validation on a Russian sample of juvenile delinquents with the emphasis on the role of personality and parental rearing
  • 2008
  • Ingår i: International Journal of Law and Psychiatry. - 0160-2527 .- 1873-6386. ; 31:5, s. 438-446
  • Tidskriftsartikel (refereegranskat)abstract
    • The objectives of the present study were 1) to validate the Antisocial Process Screening Device (APSD) in a sample of Russian juvenile delinquents; 2) to examine subgroups of delinquents with higher versus lower levels of childhood problem behaviors with respect to the APSD subscales, personality traits, and parental rearing; and 3) to attempt to replicate the previous finding that the APSD subscale measuring callous/unemotional traits can differentiate subgroups of delinquents with different precursors for problem behaviors (predominantly biological versus predominantly social). A group of 250 Russian juvenile inmates (mean age = 16.4) was examined by means of the APSD completed by the staff at the correctional institution. The inmates completed several self-reports assessing their current and childhood behavior problems, personality traits and experienced parental rearing practices. A factor structure of the APSD was obtained that is similar, albeit not identical, to that from the original studies by Frick and colleagues [Frick, P.J., O'Brien, B.S., Wootton, J.M., McBurnett, K., (1994). Psychopathy and conduct problems in children. Journal of Abnormal Psychology, 103, 700–707]; [Frick, P.J., Barry, C.T., Bodin, S.D., (1999). Applying the concept of psychopathy to children: Implications for the Assessment of antisocial youth. In Gacono, C.B. (Ed), The clinical and forensic assessment of psychopathy: A practitioners guide.

Journal of Abnormal Child Psychology, 27, 383–392]; callous unemotional traits in the present sample were expressed in manipulative behavior. Results further disclosed higher levels of antisocial and aggressive activities, higher levels of personality attributes such as narcissism and novelty seeking, as well as lower cooperativeness, and negatively perceived parental rearing in a subgroup with higher (versus lower) number of childhood symptoms of conduct disorder and oppositional disorder. The juvenile delinquents with higher levels as compared to lower levels of callous unemotional traits also perceived their parents as using more negative rearing strategies. The findings are discussed in terms of interactional processes between personality of the juvenile delinquents and parental rearing in the development of antisocial behavior.

  • Quality of Life - Towards an understanding of individuals with psychopathic tendencies
  • 2009
  • Ingår i: Personality and Mental Health. - 1932-8621. ; 3:3, s. 183-192
  • Tidskriftsartikel (refereegranskat)abstract
    • The objectives are to explore: (1) the association between psychopathy and self-rated quality of life; and (2) the possible role of childhood hyperactivity on the relationships between Psychopathy Checklist (PCL) scores and self-rated domains of Quality of Life (QoL). Male subjects with a history of criminality at age 11-14 years (n = 108) and matched controls (n = 59) from a Swedish longitudinal project were studied. Self-rated QoL domains of psychological health, family relationships and work satisfaction were dichotomized and used as dependent variables in calculations of odds ratios (ORs) with dichotomized PCL scores as the independent variable, as assessed at age 38-41. The results showed that for each of the three QoL domains, the proportion of individuals that reported dissatisfaction was significantly higher in both criminals and controls characterized by psychopathic tendencies (PT) compared with the groups with no psychopathic tendencies. Furthermore, the results revealed higher strata-specific risk of dissatisfaction among the PT individuals for two of the domains: psychological health (OR = 6.58) and work satisfaction (OR = 7.98). Childhood hyperactivity individuals were overrepresented in the PT group. However, hyperactivity did not confound the association between PCL and QoL. The results are discussed in the light of possible treatment implications.

  • Convergence of Genes and Cellular Pathways Dysregulated in Autism Spectrum Disorders.
  • 2014
  • Ingår i: American journal of human genetics. - 1537-6605. ; 94:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Rare copy-number variation (CNV) is an important source of risk for autism spectrum disorders (ASDs). We analyzed 2,446 ASD-affected families and confirmed an excess of genic deletions and duplications in affected versus control groups (1.41-fold, p = 1.0 × 10(-5)) and an increase in affected subjects carrying exonic pathogenic CNVs overlapping known loci associated with dominant or X-linked ASD and intellectual disability (odds ratio = 12.62, p = 2.7 × 10(-15), ∼3% of ASD subjects). Pathogenic CNVs, often showing variable expressivity, included rare de novo and inherited events at 36 loci, implicating ASD-associated genes (CHD2, HDAC4, and GDI1) previously linked to other neurodevelopmental disorders, as well as other genes such as SETD5, MIR137, and HDAC9. Consistent with hypothesized gender-specific modulators, females with ASD were more likely to have highly penetrant CNVs (p = 0.017) and were also overrepresented among subjects with fragile X syndrome protein targets (p = 0.02). Genes affected by de novo CNVs and/or loss-of-function single-nucleotide variants converged on networks related to neuronal signaling and development, synapse function, and chromatin regulation.

  • Biological insights from 108 schizophrenia-associated genetic loci
  • 2014
  • Ingår i: Nature. - 0028-0836 .- 1476-4687. ; 511:7510, s. 421-427
  • Tidskriftsartikel (refereegranskat)abstract
    • Schizophrenia is a highly heritable disorder. Genetic risk is conferred by a large number of alleles, including common alleles of small effect that might be detected by genome-wide association studies. Here we report a multi-stage schizophrenia genome-wide association study of up to 36,989 cases and 113,075 controls. We identify 128 independent associations spanning 108 conservatively defined loci that meet genome-wide significance, 83 of which have not been previously reported. Associations were enriched among genes expressed in brain, providing biological plausibility for the findings. Many findings have the potential to provide entirely new insights into aetiology, but associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses. Independent of genes expressed in brain, associations were enriched among genes expressed in tissues that have important roles in immunity, providing support for the speculated link between the immune system and schizophrenia.
