Depression and the social developmental context of adolescence.

This article examines the interrelations of personal and social factors in fostering longitudinal patterns of depressive symptoms, using 3 waves of data from high school students in the Boston area. Previously depressed and nondepressed youths differed markedly in their emotional responsiveness to family and friend relations. Chronically depressed youths were unresponsive to family problems, but were highly reactive to peer relations. Among previously asymptomatic youths, family relations exerted greater effects on depressed mood than relations with peers. Further analyses suggest a process through which chronic family turmoil shapes long-term mental health while also intensifying the distancing from family and investment in peer relationships that typically occurs in adolescence. Findings illustrate the importance of modeling transactions between personal and environmental factors in research on adolescent mental health and development.
