    Experiences and perceptions of participants and staff involved in HIV research in Gugulethu, South Africa
    (2019) Gomba, Yolanda; Colvin, Christopher; Trafford Zara
    It is important to understand the experiences and perceptions of HIV research from the perspectives of persons who have either participated in or worked on HIV research in lowresource settings. Obtaining such information is important because research in low-resource settings presents several ethical challenges that result in the vulnerability of participants due to factors such as low literacy levels, high rates of food insecurity and unemployment. Conducting research on the aforementioned can help researchers to design studies that mitigate some of the ethical challenges associated with conducting HIV research in lowresource communities. This dissertation adds on to existing literature on the experiences and perceptions of HIV research participants and staff involved in HIV research in low-resource settings. This dissertation is divided into three parts. Part A (Research protocol) discusses the importance of evaluating research participants’ experiences and perceptions of HIV studies conducted in lowresource settings. The section also outlines the purpose of the study, research questions, methodology, ethical considerations, rigour, reimbursement and dissemination of results. Part B (Literature review) presents an overview of the literature on HIV research in low-resource settings, with a specific focus on: ethical challenges, factors that contribute to participants’ decisions to participate in HIV research and findings from other studies which examined experiences and perceptions of HIV research in low-resource settings. The section also identifies gaps in the existing literature. Part C (Journal article) presents the findings of the study and the implications thereof.

    Re-recruiting postpartum women living with HIV into a follow-up study in Cape Town, South Africa

    Abstract Objective Recruitment and retention present major challenges to longitudinal research in maternal and child health, yet there are few insights into optimal strategies that can be employed in low-resource settings. Following prior participation in a longitudinal study following women living with HIV through pregnancy and breastfeeding in Cape Town, women were re-contacted at least 18 months after the last study contact and were invited to attend an additional follow-up visit. We describe lessons learnt and offer recommendations for a multiphase recruitment approach. Results Using telephone calls, home visits, clinic tracing and Facebook/WhatsApp messages, we located 387 of the 463 eligible women and successfully enrolled 353 (91% of those contacted). Phone calls were the most successful strategy, yielding 67% of enrolments. Over half of the women had changed their contact information since participation in the previous study. We recommend that researchers collect multiple contact details and use several recruitment strategies in parallel from the start of a study. Participants in longitudinal studies may require frequent contact to update contact information, particularly in settings where mobility is common.
