Family structure and substance use problems in adolescence and early adulthood: examining explanations for the relationship

FRANÇAIS :
Les données ont été collectées entre 1998 et 2000 dans le cadre d'une étude sur la prévalence et la distribution de troubles psychiatriques et d'abus de drogues parmi de jeune adultes (N=1760) du Sud de la Floride. Différents types de famille ont été étudiés (bi et mono-parentale). Le facteur le plus évident est l'association de 2 éléments : la présence de pairs déviants et l'exposition au stress. La structure familiale s'avère être un marqueur de la distribution inégale de facteurs influençant les risques d'usage de drogues.

Aims: Our study has two goals: to evaluate variation in symptoms of substance abuse/dependence by family structure and to examine several potential explanations for this association, including differences in socio-economic status, social support, social stress and perceived approval and use of substances by family and friends. Design: Ordinary least squares (OLS) regression is used to examine the association between family type and problematic substance use and to assess the hypothesized mediators. Setting: Data were collected between 1998 and 2000 as part of a study of the prevalence and social distributions of psychiatric and substance use disorders. The study involved face-to-face interviews with a representative sample of young adults in a South Florida community. Participants: Respondents (n = 1760) were between 18 and 23 years of age. Approximately 25% were of Cuban origin, 25% other Caribbean basin Hispanic, 25% African American and 25% non-Hispanic white. Measurements: Four family types are examined: motherfather families, single-parent families, single-parent families that include other adult relative(s) and stepfamilies. Problematic substance use is measured by a set of 22 substance abuse/dependence symptoms. Findings: Controlling for raceethnicity and gender, respondents from single-parent families report a significantly higher level of problematic substance use than those from motherfather families. Although nearly all explanations receive support, we find the strongest evidence for differential association with deviant peers and exposure to stress. Conclusions: Our findings suggest thatrather than representing a unique and independent predictor of substance use problemsfamily structure can be viewed as a marker of the unequal distribution of factors influencing the risk of problematic substance use.
