Friendships and romantic relationships may function as protective and risk factors for psychopathic traits. To better understand potential causal associations, we investigated whether within-individual changes in relationship characteristics were related to changes in psychopathic traits over time. Data were derived from ten repeated measurements of the Pathways to Desistance longitudinal study of 1354 offending adolescents (14.3% female; 40.1% Black). Analyses were adjusted for age, gender, ethnicity, self-reported offending and living facilities. Relationships of high quality were associated with lower psychopathic traits, whereas antisocial behavior and antisocial influence in relationships were related to higher psychopathic traits. Within-individual analysis indicated that time-invariant individual characteristics did not confound these associations. The findings suggest that the quality and antisocial activities of interpersonal relationships can affect positively or negatively on the levels of psychopathy.
SUMMARYThe aim of this study was to explore the relationship between sleep, including both qualitative and quantitative aspects, and delinquent behaviour while controlling for psychopathic features of adolescents and parental supervision at bedtime. We analysed data from a nationally representative sample of 4855 Finnish adolescents (mean age 15.3 years, 51% females). Sleep problems, hours of sleep and delinquency were evaluated via self-report. Psychopathic features were measured with the Antisocial Process Screening Device -Self-Report. In negative binomial regressions, gender and sleep-related variables acted as predictors for both property and violent crime after controlling for psychopathic features and parental supervision at bedtime. The results suggest that both sleep problems (at least three times per week, at least for a year) and an insufficient amount of sleep (less than 7 h) are associated with property crime and violent behaviour, and the relationship is not explained by gender, degree of parental supervision at bedtime or co-occurring psychopathic features. These results suggest that sleep difficulties and insufficient amount of sleep are associated with delinquent behaviour in adolescents. The significance of addressing sleep-related problems, both qualitative and quantitative, among adolescents is thus highlighted. Implications for a prevention technique of delinquent behaviour are discussed.
Parental behaviors may shape levels of psychopathic traits and antisocial outcomes among youth. To better evaluate the potential causality of these associations, we used eight follow-ups from the Pathways to Desistance study of 1354 offending adolescents (14.3% female; 40.1% black) and examined whether within-individual variation in parenting over time was associated with within-individual variation in psychopathic traits and offending. Multilevel regression models were adjusted for age, gender, ethnicity, contact with parental figure, and self-reported offending. Adolescent self-reported parental warmth was associated with lower psychopathic traits, and parental hostility with higher psychopathic traits. The results indicated that the more supportive and nurturing the parent, the lower the levels of psychopathic traits, whereas the more hostile the parent, the higher the levels, respectively. In addition, self-reported offending was predicted by higher parental hostility and lower maternal warmth. In time-lagged analysis, psychopathic traits did not predict parental behaviors. In young offenders parental warmth may protect against development of psychopathic traits in adolescence, whereas parental hostility may strengthen these traits. We conclude, that parenting quality matters in adolescence. Warm parenting style at this developmental period associates with lower psychopathic features among young offenders possibly lowering the risk of further criminal activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
