Intellectual engagement (IE) refers to enjoyment of intellectual activities and is proposed as causal for knowledge acquisition. The role of IE for cognitive development was examined utilizing 2-year longitudinal data from 112 ninth graders (average baseline age: 14.7 years). Higher baseline IE predicted higher baseline crystallized ability but…

Parental involvement in education remains important for facilitating positive youth development. This study conceptualized parental involvement as a multidimensional construct--including school-based involvement, home-based involvement, and academic socialization--and examined the effects of different types of parental involvement in 10th grade on…

The long-term import of a fundamental challenge of adolescent social development--establishing oneself as a desirable peer companion while avoiding problematic behaviors often supported within peer groups--was examined in a community sample of 184 adolescents, followed from ages 13 to 23, along with parents, peers, and romantic partners. The…

This study explored how neighborhood characteristics may relate to African American adolescents' internalizing symptoms via adolescents' social support and perceptions of neighborhood cohesion. Participants included 571 urban, African American adolescents (52% female; "M" age = 17.8). A multilevel path analysis testing both direct and…

The influence of the sleep patterns of 2,259 students, aged 11 to 14 years, on trajectories of depressive symptoms, self-esteem, and grades was longitudinally examined using latent growth cross-domain models. Consistent with previous research, sleep decreased over time. Students who obtained less sleep in sixth grade exhibited lower initial…

Examined adolescents' peer structures and the quality of their friendships as antecedents of romantic relationships among 180 high schoolers followed from grade 9 through 11. Found that small groups of close friends predicted other-sex peer networks that, in turn, predicted the emergence of future romantic relationships. Found indirect effects for…

Two studies of adolescents in England and Russia examined the effects of prolonged instruction on students' development of abstract deductive reasoning and understanding of logical necessity in algebraic and verbal reasoning. Results indicated that prolonged instruction emphasizing the metalevel of algebraic deduction contributed to enhanced…

Event history analysis, spanning grades 7 through 12, was used to test a developmental model of the timing of first sexual intercourse among boys at risk for delinquency. As predicted, antisocial/delinquent behavior and substance use along with early physical maturity and parental transitions predicted early onset of sexual intercourse. Anxiety…

Examined links between parental knowledge and adolescent delinquent behavior for correlated rates of developmental change and reciprocal associations from age 14 to 18. Found that parent knowledge was negatively correlated with delinquent behaviors at age 14 and knowledge increases over time were negatively correlated with increases in…

Tested model relating girls' pubertal timing to mothers' history of psychopathology, mediated by family discord and father absence/stepfather presence. Found that mothers' history of mood disorders predicted earlier daughters' puberty, with the relation fully mediated by dyadic stress and biological father absence. Stepfather presence best…

Examined the relationship between students' stress and social support in junior high school and the same students' psychological distress and school performance two years later. Stress and support variables predicted subsequent psychological distress. Stresses, but not supports, predicted subsequent school performance. (BC)

A sample of 183 third through sixth grade students were administered the Revised Class Play (RCP). Seven years later, these children and their parents completed a questionnaire measuring the students' behavioral symptoms and social, athletic, and academic competence. The RCP scores were related to adolescent competence and psychopathology. (BC)
