Preventive misconception as a motivation for participation and adherence in microbicide trials: evidence from female participants and male partners in Malawi and Zimbabwe.

This paper presents empirical data on motivation to join an HIV prevention trial of vaginal microbicide gels in Malawi and Zimbabwe, and participant assumption of a preventive misconception. Interviews were conducted with women participating in the trial and their male partners. Most of the female participants were able to adequately describe basic aspects of the trial design. HIV counseling and testing were primary reasons motivating women's participation, and male partners' support of the trial. 29% of women and 20% of men also provided indications of a preventive misconception, attributing gel use and trial participation to avoiding HIV infection.
