We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother–adolescent and father–adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and nonpassive genotype–environment correlation based on biometric moderation findings. The findings indicated that nonpassive gene–environment correlation played a stronger role for positivity in mother– and father–adolescent relationships in families with older adolescents than in families with younger adolescents, and that passive gene–environment correlation played a stronger role for positivity in the mother–adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed.

Adolescent self-harm with and without suicidality: cross-sectional and longitudinal analyses of a Swedish regional register / Johan BJUREBERG in Journal of Child Psychology and Psychiatry, 60-3 (March 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-3 (March 2019) . - p.295-304 Titre : Adolescent self-harm with and without suicidality: cross-sectional and longitudinal analyses of a Swedish regional register Type de document : texte imprimé Auteurs : Johan BJUREBERG, Auteur ; Anna OHLIS, Auteur ; B.

CEDERLOF, Auteur ; Clara HELLNER, Auteur Article en page(s) : p.295-304 Langues : Anglais (eng) Mots-clés : Self-harm  cohort study  epidemiology  self-injurious behavior  suicidal ideation Index. décimale : PER Périodiques Résumé : BACKGROUND: Self-harm is common and there is a need for studies that investigate the relevance of this behavior in clinical samples to inform risk assessment and treatment. The objectives in the current studies were to compare clinical and psychosocial correlates and subsequent adverse outcomes in youth who present to child and adolescent mental health services (CAMHS) with self-harm only (SH), self-harm with suicidality (SH+SU), with those without any indication of SH or SH+SU. METHODS: We conducted a case-control study and a longitudinal cohort study using data from a regional clinical care register, and Swedish national registers. The case-control study included all patients (5-17 years) between 2011 and 2015 (N = 25,161). SH and SH+SU cases were compared with controls (patients without SH) regarding a range of correlates. The longitudinal study included former CAMHS patients (N = 6,120) who were followed for a median time of 2.8 years after termination of CAMHS contact regarding outcomes such as clinical care consumption, social welfare recipiency, and crime conviction. RESULTS: In the case-control study, both the SH and SH+SU groups received more clinical care, had lower global functioning, and higher odds of having mental disorders compared to controls. In most comparisons, the SH+SU group had more problems than the SH group. In the longitudinal study, the same pattern emerged for most outcomes; for example, the adjusted hazard ratio for recurrent care due to self-harm was 23.1 (95% confidence interval [CI], 17.0-31.4) in the SH+SU group compared to 3.9 (95% CI, 2.3-6.7) in the SH group. CONCLUSIONS: Adolescent patients presenting with self-harm have higher risks for adverse outcomes than patients without self-harm. Suicidality in addition to self-harm is associated with more severe outcomes, importantly recurrent episodes of care for self-harm.

Advancing paternal age and offspring violent offending: A sibling-comparison study / Ralf KUJA-HALKOLA in Development and Psychopathology, 24-3 (August 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-3 (August 2012) . - p.739-53 Titre : Advancing paternal age and offspring violent offending: A sibling-comparison study Type de document : texte imprimé Auteurs : Ralf KUJA-HALKOLA, Auteur ; Yudi PAWITAN, Auteur ; Brian M. D'ONOFRIO, Auteur ; Niklas LANGSTROM, Auteur ; Paul LICHTENSTEIN, Auteur Année de publication : 2012 Article en page(s) : p.739-53 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children born to older fathers are at higher risk to develop severe psychopathology (e.g., schizophrenia and bipolar disorder), possibly because of increased de novo mutations during spermatogenesis with older paternal age. Because severe psychopathology is correlated with antisocial behavior, we examined possible associations between advancing paternal age and offspring violent offending. Interlinked Swedish national registers provided information on fathers' age at childbirth and violent criminal convictions in all offspring born from 1958 to 1979 (N = 2,359,921). We used ever committing a violent crime and number of violent crimes as indices of violent offending. The data included information on multiple levels; we compared differentially exposed siblings in within-family analyses to rigorously test causal influences. In the entire population, advancing paternal age predicted offspring violent crime according to both indices. Congruent with a causal effect, this association remained for rates of violent crime in within-family analyses. However, in within-family analyses, we found no association with ever committing a violent crime, suggesting that factors shared by siblings (genes and environment) confounded this association. Life-course persistent criminality has been proposed to have a partly biological etiology; our results agree with a stronger biological effect (i.e., de novo mutations) on persistent violent offending.

METHODS: Longitudinal cohort study based on 1,855 youths was clinically assessed for NSSI and SA, and followed up (from December, 2011 to December 2013) for the outcomes; diagnosed self-injury, alcohol/substance use disorder, and psychiatric inpatient care data derived from Swedish registers. Hazard ratios (HRs) and 95% confidence intervals (CIs) of the outcomes were estimated with Cox regressions, and additionally adjusted for the potential effect of sex and the number of clinical assessments. NSSI and SA were treated as time-varying covariates. RESULTS: Youths with NSSI had elevated risks of all outcomes, compared with youths without NSSI or SA; the HR was 2.3, 95% confidence interval [1.6, 3.4] for self-injury, 1.4 [0.9, 2.1] for alcohol/substance use disorder, and 1.3 [1.0, 1.7] for psychiatric inpatient care. Youths with SA displayed higher risks for the outcomes than the NSSI group; the HR was 5.5 [2.4, 12.6] for self-injury, 2.0 [0.9, 4.4] for alcohol/substance use disorder, and 2.6 [1.5, 4.5] for psychiatric inpatient care. Youths with both NSSI and SA showed similar risks as youths with SA; HR 4.1 [2.0, 8.3] for self-injury, 2.0 [1.1, 4.1] for alcohol/substance use disorder, but a higher risk of psychiatric inpatient care; HR 5.0 [3.1, 7.9]. All results remained virtually unchanged in the adjusted analyses. CONCLUSIONS: Youths with NSSI and/or SA had higher risks for subsequent adverse clinical outcomes. These excess risks were more pronounced among youths with SA and youths with both NSSI and SA, and the risk for psychiatric inpatient care was particularly high in youths with both NSSI and SA. Our findings suggest that early interventions for youths with NSSI or SA should not exclusively focus on suicide prevention, but also consider the risk of subsequent alcohol/substance use disorder.

Little is known about how genetic and environmental factors influence autism and autistic traits into adulthood. We aimed to determine age effects on the heritability of clinically diagnosed autism and the etiological stability of autistic traits from childhood to adulthood using twin methods. Methods From 23,849 twin pairs in the Swedish Twin Register born between 1959 and 2010, we identified 485 individuals (1.01%, 31.5% female) with a clinical autism diagnosis. We estimated and compared the relative contribution of genetic, shared, and nonshared environmental influences to autism in childhood and adulthood. We further used multivariate twin analysis with four measurement points among 1,348 twin pairs in the longitudinal Twin Study of Child and Adolescent Development to assess the phenotypic and etiological stability of autistic traits - measured with three scales from the Child Behavior Checklist - from childhood to adulthood. Results Autism heritability was comparable from childhood, (96% [95% CI, 76-99%]) to adulthood (87% [67-96%]). Autistic traits were moderately stable (phenotypic correlation = 0.35-0.61) from childhood to adulthood, and their heritability varied between 52 and 71%. We observed stable as well as newly emerging genetic influences on autistic traits from ages 8-9 to 19-20, and unique nonshared environmental influences at each age. Conclusions Genetic factors are important for autism and autistic traits in adulthood and separate genetic studies in adults are warranted.
