This study examined whether adolescent students' externalizing behavior and prosocial behavior affects their academic achievement (i.e., school grades and standardized test scores) in two major academic domains (i.e., mathematics and German) over and above well-established determinants of school achievement (i.e., prior achievement, intelligence,…

We report the results of a convergent validity study examining the externalizing subscale (SRSS-E5, five items) of the adapted Student Risk Screening Scale for Internalizing and Externalizing (SRSS-IE 9) with the externalizing subscale of the Teacher Report Form (TRF) with two samples of K-12 students. Results of logistic regression and receiver…

The current study examines the extent to which associations between internalizing problems, body mass index (BMI), and language skills from early (36 months) to late childhood (fifth grade) are due to relatively stable between-child differences, time-specific correlations, or cross-lagged paths. Data from the NICHD study, Early Child Care and…

Few longitudinal studies examine how "changes" in parent-child relationships are associated with changes in youth internalizing problems. In this longitudinal study, we investigated how developmental trends (linear change) and year-to-year lability (within-person fluctuations) in parental warmth and hostility across Grades 6 to 8 predict…

Although the assertion that marital hostility relates to higher levels of youth adjustment difficulties has been well established, few studies have examined cooperative marital conflict in relation to youth behavior problems. This study examined the main and moderating effects of cooperative marital conflict on youth behavior problems in a sample…

This study explored the relations among self-reported bully participant role behaviors (i.e., bullying, assisting, experiencing victimization, defending, and outsider behavior) and self-reported social skills (i.e., cooperation, assertion, empathy, and self-control) among boys and girls. The sample consisted of 636 middle school students (52%…

Concerns regarding the social-behavioral maladjustment of U.S. youth have spurred efforts among educators and policymakers to identify and remedy educational contexts that exacerbate children's anxiety, depression, aggression, and misconduct. However, investigations of the influence of collective classroom student characteristics on individuals'…

The impact of a school-based violence prevention program, Second Step, on peer victimization and aggression, and emotion regulation was evaluated among 457 sixth graders. A cluster-randomized trial was conducted with classrooms randomly assigned to intervention (n = 14) or control (n = 14) conditions. A repeated measures analysis of covariance on…

Guided by a risk and resilience framework, the current study examined the associations between Latino adolescents' ("n" = 219; "M" [subscript age] = 14.35; "SD" = 1.75) perceptions of ethnic discrimination in multiple settings (e.g., online, school) and several domains of adjustment (e.g., mental health, academic),…

This study examined online communication on social networking web pages in a longitudinal sample of 92 youths (39 male, 53 female). Participants' social and behavioral adjustment was assessed when they were ages 13-14 years and again at ages 20-22 years. At ages 20-22 years, participants' social networking website use and indicators of friendship…

Maternal depression has been implicated in the development of adolescent substance use. Conceptualizing depression as a continuum, the aims of this study are to (a) understand the relationship between maternal depressed mood and risk factors associated with adolescent substance use; (b) understand the relationship between maternal depressed mood…
