Methods: A sample of 850 predominately (80%) Black adolescents was assessed at baseline, 12-, 24-, and 36-months post-baseline. Participants completed measures of family conflict and parent support at each timepoint. At 36-months post-baseline, levels of HIV/STI sexual risk behaviors, including early sex initiation, unprotected sex and alcohol or illicit drug use before last sexual intercourse, and STIs were also assessed.
Results: Latent class growth analyses yielded four-class solutions for family conflict and parent support. With respect to family conflict, adolescents with high or increasing family conflict trajectories were at greater risk of STI/HIV sexual risk behaviors and STIs. Adolescents with high or increasing parent support trajectories were at lower risk of STI/HIV sexual risk behaviors and STIs. Yet, the additional trajectories differ across outcomes highlighting the complexities of the role of family functioning on HIV/STI sexual risk behaviors and STIs over time.
Implications: The family, the most proximal system to adolescent development, may play an important role in ameliorating adolescent HIV/STI risk behaviors and STIs over time. Findings suggest that social work preventive interventions targeting parent support and family conflict may be efficacious at preventing and reducing HIV/STI risk behaviors, including drug use and sexual risk behaviors. Social work research, practice and policy implications are discussed.
