title: Differential contributions of family and peer factors to the etiology of narcotic addiction.
abstract: This retrospective study investigated relationships among early family circumstances, peer associations, and narcotic addiction in a sample of 601 urban males. Results of logistic regression analyses indicated that the extent of deviant behavior among close friends at ages 12-14 and disruption in family structure (parental divorce/separation) prior to age 11 were significantly associated with narcotic addiction. Additional regression analyses indicated that deviant behavior among family members, as well as family disruption, experienced prior to age 11, also increased the probability of association with deviant peers and a negative home atmosphere at ages 12-14. Implications of these findings for preventive interventions and for future research are presented.
