Evaluating the Role of Family Context Within a Randomized Adolescent HIV-Risk Prevention Trial.

Project STYLE is a multi-site 3-arm RCT comparing family-based, adolescent-only, and general health promotion interventions with 721 adolescents in mental health treatment. This study reports 12-month outcomes for family context and sexual risk behaviors, and explores the role of baseline family context in modifying treatment response. Using the full sample, there were sustained benefits for parent-reported sexual communication (d = 0.28), and adolescent-reported parental monitoring (d = 0.24), with minimal differences in risk behaviors. Latent profile analysis identified four family context classes: struggling (n = 177), authoritative (n = 183), authoritarian (n = 175), and permissive (n = 181). The authoritarian and permissive classes were also distinguished by disagreement between parent and adolescent report of family context. Classes differed in terms of baseline mental health burden and baseline sexual risk behavior. Classes showed different patterns of treatment effects, with the struggling class showing consistent benefit for both family context and sexual risk. In contrast, the authoritarian class showed a mixed response for family context and increased sexual risk.
