Detaillierte Beschreibung
The CPOL intervention is a local adaptation of an intervention package developed with Black men-who-have-sex-with-men (MSM) in the United States. This pilot trial studies both the overall effectiveness of this adapated intervention in rural South Africa, and the differential benefit of selecting participants using three different methods: 1) at random; 2) based on peer nominations of local opinion leaders; 3) based on a community-wide social network built from nominations of important social contacts. While the primary outcome is quantitative, the study is not powered to see statistically significant differences between arms. The evaluation focus of the pilot trial is the process evaluation, which will follow the RE-AIM framework to assess how and why the intervention worked, failed or needed adjustment. The end result will be a CPOL-style intervention package that may (or may not) be appropriate for rural South Africa, and a methodology for adapting CPOL packages for other sexual health contexts.
The process evaluation will include qualitative group and in-depth one-to-one interviews with: (i) session trainers; (ii) POL trainees; (iii) peers in the local community; (iii) HIV service providers. It will also include a short pre/post questionnaire for all trainees to capture key knowledge and attitude outcomes relating to the training.

Experimental: Random selection
Invitation to participate in the group training is based on a random selection from all age-eligible individuals in the study area

Trained research assistants will deliver four two-hour training sessions to a group of ~20 young adults, leading to the trainees providing sexual health information and HIV self-tests (with onward self-referral to local clinics) to their friends and close contacts.
Sessions include training on local sexual health information, effective communication strategies, practice conversations and feedback.
