Investigating the age effects of family structure on adolescent Marijuana use

This study examines differences among older and younger adolescents in the influence of family structure, family relations, and peer relations on marijuana use. Data from a longitudinal sample of adolescents from the United States were stratified by age and used to assess these potential differences. Precise measures of family structure were constructed to account for the various manifestations of family forms. Multivariate analyses indicate that a recent divorce attenuates attachment among younger adolescents and leads to less family involvement among older adolescents. Moreover, older adolescents from stepparent families are less attached to their families. Changes in these family relationship variables influence associations with drug using peers, but these processes differ for the two age groups. Finally, less family involvement and greater drug using peer associations lead to greater marijuana use among younger adolescents, while only peer associations directly affect use among older adolescents.This research was partially funded by a Faculty Research Grant provided by the University of North Carolina—Charlotte.
