The intent of this project is to replicate the POWER pilot campaign using a randomized controlled trial with neighborhoods as the unit of randomization and analysis. We plan to rigorously test the effects of the POWER campaign on women’s knowledge of, attitudes toward and use of female and male condoms for the prevention of sexually transmitted disease (STD) and unintended pregnancy. We will work in 12 non-contiguous neighborhoods in four southwestern U.S. cities (four each in Oakland/Alameda County and Los Angeles and two each in San Diego and Las Vegas). We will complete a baseline assessment in all 12 neighborhoods to document knowledge of, attitudes toward and use of female and male condoms. We will then randomly assign six neighborhoods to intervention status and six neighborhoods to control status. We will adapt the campaign for each city, and implement it in six intervention neighborhoods for nine months, and will complete a follow-up assessment similar to the baseline assessment, with added questions regarding exposure to the POWER campaign. Study partners include Dr. Sheana Bull and research staff from the Colorado Health Outcomes Program (COHO) of the University of Colorado Health Sciences Center, Educational Message Services (EMS), and Centers for Disease Control and Prevention (CDC).
