The Role of Attachment to Family, School, and Peers in Adolescents' Use of Alcohol: A Longitudinal Study of Within-Person and Between-Persons Effects.

A great deal of time and money has been spent to understand why adolescents abuse alcohol. Some of the most fruitful work considers the social context navigated by adolescents, including family, school and peer contexts. However, most of this work focuses on differences between adolescents in these contexts. The present study adds to the literature by considering within-person changes in these contexts and examines the extent to which these changes are related to alcohol use. Significant changes in all three contexts were observed, and these changes were significantly related to alcohol use. The significant influence of intrapersonal variability highlights the importance of attending not only to chronic, between-individual issues facing at-risk youth, but emergent and transient issues that may temporarily heighten alcohol use risk.
