This study tested two competing models of differential susceptibility and diathesis-stress in a prospective longitudinal study of African American youths (N = 935). It examined whether individual variations in the functioning of the hypothalamic-pituitary-adrenocortical axis at age 11 interact with middle childhood parent-child relationship…

A cross-sectional study was designed to analyze this phenomenon among students aged between 13 and 17 years. A sample of 1462 students participated, 18.46% of which reported having planned suicide, 56.16% reported…

Background: Friendship is important to quality of life, yet people with intellectual disability have more restricted social networks and fewer friends outside family and support staff.

This study examined how peer norms condition the effect of romantic involvement on adolescents' externalizing and internalizing problem behaviors. We hypothesized that, as a result of social control and social learning, adolescents who start a romantic relationship report more problem behavior when romantic involvement was not normative behavior…

Gender and race differences were observed on relational…

This study examined the associations between sibling intimacy and conflict and youths' reports of risky behavior in a sample of adolescents ages 11-20. Participants were mothers, fathers, and sibling dyads in 393 families who were interviewed annually for 3, 4, or 5 years. Multivariate multilevel models tested longitudinal links between sibling…

Research suggests that sibling--peer connections are important for understanding adolescent problem behaviors. Using a novel behavioral genetic design, the current study investigated peer network overlap in 300 child--child pairs (aged 7-13 years) in 5 dyad types: monozygotic (MZ), dizygotic twins, full siblings (FSs), friend pairs, and virtual…

Previous studies of the association between multiple parental relationship transitions (i.e., when a parent begins or terminates an intimate relationship involving cohabitation) and offspring antisocial behavior have varied in their efforts to rule out confounding influences, such as parental antisocial behavior and low income. They also have been…

Background: Children who have been exposed to intimate partner violence (IPV) experience a wide variety of short-term social adjustment and emotional difficulties, including externalizing behavioral problems such as aggression. While children are affected by IPV at all ages, little is known about the long-term consequences of IPV exposure at…
