The purpose of this study was to clarify parents' role in the initiation of
alcohol use of young adolescents. Subjects included 413 adolescent-parent
dyads in which the youth had not begun drinking at the end of 6th grade. Al
l dyads were participants in Project Northland (PN), an adolescent alcohol
use prevention trial. A proposed etiologic model including parent norms rel
ated to underage drinking, household alcohol-related problems, family probl
ems, and potential mediators of parent influence was tested using structura
l equation modeling techniques. To explore model differences between interv
ention conditions, separate models were estimated for intervention and refe
rence samples. Among the parent constructs modeled, parent norms around und
erage drinking exhibited the strongest relationships with 7th- and 8th-grad
e alcohol use. Parent norms were directly related to adolescents' alcohol-r
elated cognitions, and thereby had a significant indirect relationship with
teenagers' alcohol use. No significant differences were found between inte
rvention and reference groups in model-specified pathways to alcohol use.
