African-American and Puerto Rican drug use: personality, familial, and other environmental risk factors

Using a family interactional theoretical framework giving primacy to the mutual attachment between parent and child, we examined the interrelationship of acculturation, ecological factors, family, personality, peers, and drug context domains with drug use in an inner city sample. We also assessed the extent to which family protective factors mitigated against risks for drug use from most of the other domains. The sample consisted of 695 African-American and 637 Puerto Rican 7th-10th graders who answered the questionnaire while listening to it on personal tape players in their classrooms. The results of hierarchical regression analyses sufficiently supported the hypothesized sequence of interrelationships in both ethnic groups to substantiate our developmental model of drug use. We also found protective buffers common to both ethnic groups and buffers specific to each group. The implications of the results for targets and timing of intervention in the path to drug use are discussed.
