NIMH Collaborative HIV/STD Prevention Trial

This 8-year study was part of the National Institute of Mental Health (NIMH) Collaborative HIV/Sexually Transmitted Disease (STD) Prevention Trial in international settings, including China, India, Peru, Russia, and Zimbabwe. The trial was designed to identify, recruit, train, and engage community popular opinion leaders (C-POL) in a defined population to convey HIV risk reduction messages. The primary objective was to reduce HIV/STD incidence and risky sexual behaviors.
