Aim:
The Popular Opinion Leader (POL) intervention has been shown to be effective in reducing risky sexual behavior. This is a diffusion-based model, purportedly changing norms through conversations led by popular individuals who are recruited to become change agents. POLs are taught conversational skills to bring about this normative change. One of the shortcomings of this model is that the conversations are not structured around strong behavioral theory to increase the chances of motivating behavior change among community members. Thus, conversations may not be nearly as effective as they could be.
 
Method / Issue:
In Zimbabwe, while conducting an intervention trial based on the POL model, we used the Integrated Behavioral Model (IBM) to identify constructs (attitude, norm, self-efficacy, facilitators, barriers) most related to safe sex behaviors among community members. The IBM-based survey instrument measured factors affecting intention to use condoms with various partners, monogamy, and avoiding commercial sex workers (CSWs). As part of the assessment of the POL intervention, the survey was administered to individuals in 30 rural growth points. Analyses of data assessed how well the IBM constructs and their underlying beliefs explain these safe sex behavioral intentions.
 
Results / Comments:
IBM measures of attitude, subjective norm, partner norm, and self-efficacy were each significantly associated with participants intentions to use condoms with their spouse, steady partner, casual partner and CSW, avoiding CSWs, and to stick to one partner. Our research shows that these behavioral constructs may be key to target in each safe sex intention.
 
Discussion:
Application of the IBM successfully identified the most important constructs to target by interventions to change behavior. Focusing on norms may not be sufficient to change behavior. Targeting attitudes towards these behaviors, as well as partner norms, self-efficacy, and reducing barriers may have a larger impact on changing behavior than just relying on normative change. Thus, we have designed a tool, a conversation guide to better focus conversations on constructs likely to impact behavior. This tool will be demonstrated.
