Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

This study examined the relations between normative developmental changes of familism values and later internalizing and externalizing behaviors in Latinx adolescents from an emerging immigrant community. The sample included 547 Latinx adolescents (55.4% female; baseline M[subscript age] = 12.80; SD = 1.03) residing in the Southeastern United…

Using coercive strategies to resolve conflicts with romantic partners has toxic effects on relationships. Coercion predicts relationship dissatisfaction, instability, and intimate partner violence. The early adult romantic relationships model hypothesizes that such strategies first emerge within the family and continue to affect romantic…

Parental warmth and hostility are two key dimensions of parenting for child development, but the differential effects of these parenting dimensions on child prosocial and antisocial development has not been adequately investigated. The current study hypothesized that parental warmth would be uniquely related to child callous-unemotional traits and…

The goal of this study was to broaden the developmental understanding of the implications of interparental conflict (IPC) and threat appraisals of conflict for adolescents' relationships with peers. Guided by the cognitive contextual framework and evolutionary perspectives, we evaluated a developmental model in which adolescents who are exposed to…

Although negative interparental conflict predicts elevated externalizing problems for children, there are individual differences in this association. Theoretically, children's abilities to coordinate physiological stress across response systems moderate the effects of interparental conflict on developmental outcomes. Past cross-sectional research…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

Previous studies often assumed that parenting practices are similar across families. This assumption is difficult to hold, especially throughout adolescence, a period of major change for both adolescents and their parents. By combining a person-centered and a variable-centered approach, the present study adds to the literature by identifying…

Although adolescents around the world play video games, little is known about their longitudinal effects on adolescents from Eastern countries. This large longitudinal violent video game study has 4 strengths. First, it is the first longitudinal study conducted with Chinese adolescents. Second, it examines moral disengagement as a possible…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

Basic perspective taking and mentalizing abilities develop in childhood, but recent studies indicate that the use of social perspective taking to guide decisions and actions has a prolonged development that continues throughout adolescence. Here, we aimed to replicate this research and investigate the hypotheses that individual differences in…

As internalizing and externalizing problems often co-occur, the current study utilized a longitudinal dataset of 784 at-risk children (predominantly from low-income families and academically at-risk; 52.6% male) followed yearly from Grade 1 to Grade 12 to: (a) explore the heterogeneity in the codevelopment patterns of internalizing and…

The present study examined sympathetic and parasympathetic indices of autonomic nervous system reactivity as moderators of the prospective association between parental management of peers via directing of youths' friendships and peer adjustment in a sample of typically developing adolescents. Participants included 246 adolescents at Time 1 (T1)…

Prior research has demonstrated both socialization and selection effects for the relationship between antisocial peer affiliation and externalizing problems in adolescence. Less research has evaluated such effects postadolescence. In this study, a cross-lagged panel analysis was used to evaluate the extent of "socialization" (i.e., the…

Callous-unemotional (CU) behavior has been linked to behavior problems in children and adolescents. However, few studies have examined whether CU behavior in "early childhood" predicts behavior problems or CU behavior in "late childhood". This study examined whether indicators of CU behavior at ages 2-4 predicted aggression,…
