Optimizing a Multi-Modal Intervention to Reduce Health-Risking Sexual Behaviors: Component Selection

The goal of this project is to evaluate the components of the app-based intervention Mission Wellness to reduce health-risking sexual behaviors (HRSBs; e.g., condom non-use, multiple sexual partners) in active-duty members of the US Military to improve their sexual and reproductive health (SRH) and readiness to serve. Following the multiphase optimization strategy (MOST) framework, factorial component selection experiments (CSEs) will be conducted to evaluate which five experimental intervention components (i.e., Narratives, Skills, Scenarios, Future, and Risk) elicit the greatest improvements in the outcomes of interest given key constraints.
