    The Influence of Perceived Dapivirine Vaginal Ring Effectiveness on Social Disclosure and Ring Adherence
    (AIDS and Behavior, 2013) Stoner, Marie C. D.; Brown, Elizabeth R.; Palanee‑Phillips, Thesla; Mansoor, Leila E.; Tembo, Tchangani; Nair, Gonasagrie; Akello, Carolyne; Seyama, Linly; Jeenarain, Nitesha; Naidoo, Logashvari; Mgodi, Nyaradzo; Hunidzarira, Portia; Chitukuta, Miria; Straten, Ariane van der
    We analyzed data from 1428 users of the dapivirine vaginal ring, who participated in the MTN-020/ASPIRE phase III trial and subsequent open-label extension MTN-025/HOPE trial, to examine relationships between perceived ring protection, social disclosures, and self-reported ring adherence. In HOPE, 77% perceived the ring to be highly effective, and this view was associated with speaking: (a) to a greater number of people about the study, (b) with other participants, (c) to more people who were in favor of the ring, and (d) to more people whose opinions were valued. Reported adherence was not directly associated with perceived protection but was associated with disclosing to someone who was in favor of the ring. These findings suggest the importance of women’s internalized ideas about the protective benefits of the DVR in sharing information about the ring and the importance of social support on adherence

    Rumours may influence health-related behaviours, including uptake and adherence to HIV prevention products. This ASPIRE study assessed the safety and effectiveness of a vaginal ring delivering the antiretroviral dapivirine for HIV prevention in Africa. We explored negative rumours about study participation and the vaginal ring amongst study participants and their communities in Malawi, Uganda, South Africa and Zimbabwe. Two hundred and fourteen women participated in either single or serial in-depth interviews, or a focus group discussion. Three key findings emerged in the data. Firstly, rumours reflected fears concerning the ring and trial participation. Given the historical-political context of the countries in which the trial was conducted, the ring’s investigational nature and its foreign origin, ring use was rumoured to cause negative health outcomes such as cancer and infertility and was also associated with practices such as witchcraft or Satanism; salience of these rumours varied by country. Secondly, rumours reportedly affected participants’ adherence to the ring, and other women’s willingness to participate in the study. Finally, participants reported that participant engagement activities helped address rumours, resulting in enhanced trust and rapport between staff and participants.
