PROJECT SUMMARY Drug dependence is one of the most serious national public health problems, affecting millions of individuals and their families. African-American families experience disproportionate rates of negative health and social consequences of drug abuse, even though they use drugs at rates comparable to or lower than those of European-Americans. African-American children affected by parental drug use are at an extremely high risk for a range of problems throughout childhood and into adulthood. Effective implementation of integrated prevention interventions is critical to reducing the burden of substance use disorders and directly improving public health. This Career Development Award (K01) has allowed me to obtain the additional mentoring, training and skills to achieve my long-term career goal of becoming an independent investigator with expertise in designing, implementing and evaluating prevention interventions for vulnerable African- American adolescents through partnerships with public libraries. My three training objectives were to: (1) obtain comprehensive training in the etiology of substance use among urban African-American families; (2) develop expertise in the theoretical underpinnings, processes and mechanisms of intervention development and adaptation; and (3) become proficient in implementing and evaluating randomized clinical trials using advanced statistical techniques. I achieved these goals through didactic experiences, participation in professional conferences, directed readings, and experiential learning opportunities under the mentorship of a team of experts in relevant fields of study. This mentoring and training directly contributed to the proposed research, which was designed to prevent substance use and sexual health risk behaviors among urban Black adolescents (ages 13-16) affected by parental drug use through partnerships with public libraries. There were three specific aims laid out in the research plan to: (1) identify the opportunities and barriers for engaging adolescents with a drug-abusing parent in prevention programs and health services; (2) adapt the evidence-based intervention, Focus on Youth with Informed Parents and Children Together (FOY+ImPACT) to be a virtual, library-partnered, targeted intervention for adolescents affected by parental drug use and (3) conduct a pilot study to assess the feasibility and initial efficacy of the adapted library-based prevention intervention for adolescents affected by parental drug use. Findings from the proposed research will lay the foundation for collaborative efforts that facilitate libraries’ provision of evidence-based prevention interventions to vulnerable youth, including, but not limited to, adolescents affected by parental drug use, homeless youth, as well as youth involved in the foster care and juvenile justice systems. This Administrative Supplement will allow me to complete the final research aim, which was significantly impacted by the COVID- 19 pan...
