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,…

Despite the high prevalence of and documented impairment associated with pediatric anxiety disorders, less than half of youth access mental health services. This study examined (a) the utilization of eight school services and supports (e.g., seen a school counselor for a mental health reason, placement in a special class for a behavior or…

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…

Objective: This study examined the prospective relationship from student inattention symptoms to changes in their psychological need satisfaction (PNS) during their transition to secondary school. In doing so, it has explored whether this temporal association was moderated by teachers' involvement (TI). Method: A sample of 688 students (46% male;…

Emerging research suggests that adolescents at high-achieving schools (HAS) in Western societies are at elevated risk for problem behaviours. This cross-sectional study explored whether adolescents attending HAS in a non-Western setting show similar risk patterns and if contextual (school-, family-, and peer-based) factors typically associated…

Despite the high prevalence of and documented impairment associated with pediatric anxiety disorders, less than half of youth access mental health services. This study examined: (1) the utilization of eight school services and supports (e.g., seen a school counselor for a mental health reason, placement in a special class for a behavior or…

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…

The current study evaluated bidirectional associations between mother and father positive parenting and child effortful control. Data were drawn from 220 families when children were 3, 4, 5, and 6 years old. Parenting and effortful control were assessed when the child was 3, 4, and 5 years old. These variables were used to statistically predict…

Internationally, girls outperform boys in overall school performance. The gender gap is particularly large among those in at-risk groups, such as children from families at economic disadvantage. This study modeled the academic trajectories of a low-income sample of boys and girls from the Concordia Longitudinal Risk Project across the full course…

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%…

This research examined whether following social and physical aggression trajectories across Grades 3-12 predicted psychological maladjustment. Teachers rated participants' (n = 287, 138 boys) aggressive behavior at the end of each school year. Following the 12th grade, psychosocial outcomes were measured: rule-breaking behaviors, internalizing…

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…

The sex-positive framework of sexual development hypothesizes that healthy sexual experiences can be developmentally appropriate and rewarding for adolescents despite the risks involved. Research has not examined whether risky behaviors and rewarding cognitions actually change with sexual debut at a normative or late age. This study measured the…

Throughout the developing world, adolescents living in rural poverty face multiple and inter-related adaptive challenges. Using longitudinal data from the Gansu Survey of Children and Families, we adopt an approach grounded in resilience theory to investigate the relationship between cumulative adversity and internalizing problems among 1,659…

This study examined the longitudinal relationship of early elementary predictors to adolescent depression 7 years later. The sample consisted of 938 students who have been part of a larger longitudinal study that started in 1993. Data collected from parents, teachers, and youth self-reports on early risk factors when students were in 1st and 2nd…
