This study examines the effects of a multi-level social action-based theory (SABT) intervention to increase HIV testing and consistent condom use among female commercial sex workers (FCSWs). Respondents in four socio-demographically similar Philippine cities received an SABT intervention based on: (1) peer influence; (2) manager training; (3) combined peer/manager influence; or (4) usual care (control condition). HIV testing increased 86% from baseline (N = 980) to follow-up (N = 903), and was significantly associated with higher HIV/AIDS knowledge, lower probability of contracting HIV and increased condom use. After adjusting for socio-demographic, HIV knowledge and perceived control variables, FCSWs in the manager training and combined peer/manager conditions were significantly more likely to engage in consistent condom use. Mediational analyses revealed higher HIV/AIDS risk perceptions and a supportive work environment related to increased condom use. These findings support a growing body of research suggesting the need for multi-level sexual risk reduction interventions among FCSWs.
