Knowledge Mediates the Effects of Game Changers for Cervical Cancer Prevention (GC-CCP) Intervention on Increased VIA Screening Advocacy in Uganda.

Abstract

Game Changers for Cervical Cancer Prevention (GC-CCP), a group advocacy training intervention, has been shown to increase cervical cancer prevention and screening advocacy. In this secondary analysis, we examined mediators and moderators of this effect. A randomized controlled trial of GC-CCP-a 7-session, peer led intervention designed to empower women to engage in cervical cancer prevention advocacy-was conducted with women who had recently been screened by visual inspection of the cervix with acetic acid for cervical cancer. Participants were assessed at baseline and month 6 follow-up. Cervical cancer-related constructs targeted by the intervention were examined as mediators using multivariate linear regression analysis. Individual and social network characteristics were examined as moderators. Change in cervical cancer knowledge fully mediated the intervention effect on increased cervical cancer prevention advocacy; change in cervical cancer risk management self-efficacy was a partial mediator. Moderators of the effect included no secondary education, having a main sex partner, and having trustworthy, supportive, non-stigmatizing peers. The effect of GC-CCP on cervical cancer prevention advocacy seems largely driven by its impact on cervical cancer knowledge, and the intervention may be most effective among women who are partnered, less educated, and have trusting, supportive social networks.

Prevention relevance: Enhancing cervical cancer knowledge among women who have screened for cervical cancer is key to empowering these women to engage in cervical cancer prevention advocacy and acting as change agents for encouraging other women to screen.
