Abstract
Adolescents from 1 of 3 family structures were compared with respect to their susceptibility to peer pressure to engage in deviant activity. Youngsters living with both natural parents were less susceptible to such pressure from their friends than those living in other family structures. More important, youngsters growing up in stepfamilies--in the presence of an additional adult--were equally at risk for involvement in deviant behaviour as were their peers growing up in single-parent households.
