Although studies have demonstrated that an adolescent’s parents and friends both influence adolescent substance use, it is not known whether
the parenting experienced by one’s friends also
affects one’s own use. Drawing on conceptions
of shared parenting and the tenets of coercion
theory, researchers investigated the extent to which
three domains of parenting behaviours (parental
knowledge, inductive reasoning, and consistent
discipline) influenced the alcohol, cigarette, and
marijuana use of not only their own adolescent
children but also of members of their adolescents’ friendship groups.
Analyses of friendship nominations within each of
two successive ninth-grade cohorts in 27 Iowa and
Pennsylvania schools (N = 7,439 students, 53.6%
female) were used to identify 897 friendship groups.
Hierarchical logistic regression models were used
to examine prospective associations between 9th grade
friendship group–level parenting behaviours
and adolescent self-reported alcohol, cigarette, and
marijuana use in 10th grade.
Adolescent substance use in 10th grade was
significantly related to parenting behaviours of
friends’ parents, after controlling for adolescents’ reports of their own substance use and their
own parents’ behaviours at the 9th grade level.
These associations were particularly strong for
parents’ knowledge about their children and use
of inconsistent discipline strategies. Significant
interaction effects indicated that these relationships
were strongest when adolescents received positive
parenting at home. Some, but not all, of the main
effects of friends’ parents’ parenting became nonsignificant
after friends’ substance use in ninth grade
was included in the model.
The findings suggest that the parenting style in
adolescents’ friends’ homes plays an important role in
determining adolescent substance use. Implications
of the joint contribution of parents and peers for
prevention and intervention are discussed.
