Detailed Description:

The C-POL in Alabama project is and intervention study which sought to impact the health behaviors of community residents who live in zip codes that have high syphilis morbidity. The study is being implemented in Birmingham and Montgomery with shelter clients.

The intervention model used for this study is the Popular Opinion Leader (POL) model, which is effective at reducing new HIV infections. The intent of this study was to determine the effectiveness of a diffusion model (e.g. POL) at reducing syphilis infections in affected communities.

For the intervention, community members identified as popular opinion leaders were recruited and trained to share accurate information about syphilis transmission, symptoms, testing, treatment and prevention. Prior to intervention implementation and several times after, community members were given a survey and screened for syphilis as well as 2-3 additional STDs. During each assessment, cross-sections of the community members were sampled.
