This study examined a neurobiologically informed model of the emergence of child externalizing behaviors in an ethnically diverse community sample of 232 9-12 year old children. Replicating extensive prior research, our analyses revealed that parents' inconsistent discipline and poor quality monitoring were predictive of child externalizing behavior. In addition, poor parental monitoring, but not inconsistent discipline, was associated with children having a significantly flatter morning-to-evening cortisol slope, which was in turn, related to higher levels of externalizing behaviors. An indirect effect of parental monitoring on externalizing behaviors, through child diurnal cortisol rhythms, was also supported. These findings highlight the role of the hypothalamic-pituitary-adrenal (HPA) axis and its hormonal end product, cortisol, in the relationship between the caregiving environment and the development of externalizing behaviors.

Polygenic scores (PGSs) have garnered increasing attention in the clinical sciences due to their robust prediction signals for psychopathology, including externalizing (EXT) behaviors. However, studies leveraging PGSs have rarely accounted for the phenotypic and developmental heterogeneity in EXT outcomes. We used the National Longitudinal Study of Adolescent to Adult Health (analytic = 4,416), spanning ages 13 to 41, to examine associations between EXT PGSs and trajectories of antisocial behaviors (ASB) and substance use behaviors (SUB) identified via growth mixture modeling.

Antagonism is a personality domain located in most major trait models and is central to multiple personality disorders. This construct has been linked to many societally harmful externalizing behaviors (e.g.

Objective: Changing Academic Support in the Home for Adolescents with ADHD (CASH-AA) and Medication Integration Protocol (MIP) are two family-based behavioral protocols designed to promote family solutions to academic problems and medication decision-making. Building on a randomized control trial examining these protocols, the current study examined how protocol dose, an indicator of treatment adherence, was associated with treatment outcomes.
Method: The sample consisted of 145 adolescent clients (M age = 14.

Background: Internet Gaming Disorder (IGD) is a new behavioral addiction. A large number of empirical studies have shown that Internet Gaming Disorder has a high level of comorbidity with other diseases, including depression, anxiety, obesity, internalizing and externalizing behavioral problems, however, little is known about the mediating and moderating mechanisms underlying this relation. The current study adopted a three-time longitudinal study investing the mediating effect of relative deprivation on the association between peer rejection and IGD, and whether this mediating effect was moderated by the grit.

Because educational attainment is associated with well-being in the long term, it is important to understand the developmental processes that enhance academic outcomes during adolescence. Also, although the importance of friends is well documented in adolescence, little is known about how close friends' characteristics work together with youth's own characteristics to shape adolescents' educational trajectories. This study fills an important gap in knowledge by focusing on how middle school students' academic achievement and externalizing problems are associated with their friends' achievement and externalizing problems over time, and how these variables predict educational attainment in adulthood.
