The present study examined influences of sixth-grade student-reported parent educational involvement on early adolescent peer group affiliations at seventh and eighth grade. In addition, student gender and ethnicity were explored as possible moderators. Drawn from a large effectiveness trial, participants in this study were 5,802 early adolescents…

This study examined longitudinal changes in peer network selection and influence associated with self-reported antisocial behavior (AB) and violent behavior (VB) over the course of middle school in a sample of ethnically diverse adolescents. Youth and families were randomly assigned to a school-based intervention focused on the prevention of…

Explores developmental and intervention evidence relevant to iatrogenic effects in peer-group interventions. Findings from two intervention studies involving 119 high-risk youth and 39 controls and 150 pairs of adolescent boys suggest that high-risk youth are particularly vulnerable to peer aggregations when compared to low-risk youth. Discusses…

Presented is a conceptual framework linking the construct of temperament with environmental factors that covary with the onset and escalation of substance use. We propose that transactions between temperament characteristics of the child in family and peer contexts influence the development of self-control ability, a mediating factor for onset and…

The document examines the roles of peer relations and parent monitoring in increasing children's risk of developing a deviant network of friends. Subjects were approximately 200 boys and their families. Boys were assessed in school and interviewed when 9-10 years old and when 11-12 years old. Structural equation modeling was used to evaluate the…

Assessed the characteristics that predicted the timing of first sexual intercourse in high-risk adolescents. Employed event history analyses and defined predictor variables using multimethod and multiagent assessments. Found that precocious sexual initiative can be understood using models of the etiology of other problem behavior, and that…

Studied adolescent participants in a group intervention program to determine the influence of peer reactions to problem behavior. Found that the impact of friendship is not always positive and can lead to unintended iatrogenic consequences. Concludes that adults' role in attending to children's peer contexts is perhaps the most critical for…

The problem is well known to every parent of a teenager, every high school teacher, every clinical practitioner, and every social policy maker: vulnerable adolescents risk becoming more deviant through association with deviant peers and peer groups. Deviant peer influences are among the most potent factors in the development of antisocial…
