title: Was the intervention implemented as intended?: a process evaluation of an AIDS prevention intervention in rural zimbabwe.
abstract: End-point evaluations are still the most commonly used method of assessing the success or failure of interventions. This article describes how a process evaluation was used to measure "what happened" during an HIV/AIDS prevention program for farm workers in Zimbabwe. The intervention was developed according to the Paulo Freirian theory of Social Change and the Ecological Model for health promotion. The stages of the intervention were cyclical; in the first stage innovative methods were used to encourage appraisal of vulnerability to HIV/AIDS through activities which raised critical thinking and dialogue. In the next phase, emphasis was placed on developing cognitive and attitude change in the target group. Self-protective behavior was encouraged through condom use and an increase in self-efficacy with respect to negotiating safe sex, especially among women. In the last stage of the intervention, efforts were made to create a climate for maintenance of behavior and socially responsible action within the community. The process evaluation provided valuable insight into factors which, when aggregated, provided an overview of a program whose successes and failures may well have been determined by issues outside the scope of the intervention. The effect of seasonal fluctuations of labor, income, and farming activity on program activity, patterns of STD, and condom demand were marked. This leads back to the researchers' initial question: "Was the intervention implemented as planned?" and the answer-only partially.
