The proposed project, Adopting and Demonstrating the Adaptation of Prevention Techniques (ADAPT), has two main goals: first, to assist the Centers for Disease Control and Prevention (CDC) to better understand the processes needed for adapting evidence-based behavioral interventions to fit new conditions or target populations; second, to utilize the CDC's draft adaptation guidance to adapt Jeff Kelly's Popular Opinion Leader (POL) for use with adult, seropositive Hispanic men who have sex with other men (MSM). The target population will directly participate in all phases of the intervention adaptation process.
