Abstract:
Evidence-based interventions are often disseminated in public health education with little known about their operational fidelity. This study examined the delivery of intervention components (operational fidelity) of a widely disseminated HIV prevention program designed for people living with HIV/AIDS named Healthy Relationships. Two hundred ninety-nine agencies that had been trained in the intervention by the Centers for Disease Control and Prevention were contacted, and 122 (41%) completed confidential interviews. Among the 93 agencies that implemented the program, 39 (40%) adapted at least one core element activity, and 21 (23%) dropped an activity. Most adaptations were intended to improve the community fit of the intervention. Agencies believed that funders demand that they implement the intervention with fidelity. Models of technology transfer that emphasize behavior change processes rather than specific curriculum content may advance prevention program dissemination.
