Аннотация:Substance use—including the use and co-use of alcohol, cigarettes, and illicit drugs—often emerges in adolescence. However, the longitudinal structure of polysubstance use and its social-ecological predictors are less understood. We examined (a) higher-order trajectories of polysubstance use (encompassing alcohol, cigarette, and illicit drug use) and (b) their associations with individual- and family-level factors.MethodsParticipants were 568 eighth- and tenth graders (M age = 14.46; 50.5% girls) from Miami-Dade County, FL, and Prince George’s County, MD, in a six-wave longitudinal study on alcohol use. Adolescents reported age, sex, race/ethnicity, attention problems, positive parenting, and family structure. Latent growth curve modeling was used.ResultsRacial/ethnic composition was 40.8% Hispanic, 35.0% non-Hispanic Black, 6.9% non-Hispanic White, 10.6% others, and 6.7% multiracial.
