Our two-year study will consist of qualitative approaches for intervention development, and a mixed methods pilot study to assess the newly developed intervention's acceptability, usability, and preliminary efficacy (Aim 1). We will also conduct focus group discussions (FGDs) with family caregivers to identify acceptable approaches to strengthen their supportive roles (Aim 2). For the Aim 1 research, multi-methods will be used spanning three phases: (1) in-depth interviews (IDIs) with ALHIV and dyadic interviews (DIs) with ALHIV/caregiver pairs; (2) FGDs with ALHIV and (3) a pilot study with ALHIV. In the pilot study, we will evaluate our newly developed digital intervention for pregnant adolescents living with HIV (ALHIV) in Kenya (N = 30). The intervention will be designed to increase awareness of stigma regarding HIV and pregnancy, improve disclosure self-efficacy skills, and facilitate enlistment of family members as social support allies. The goal of the intervention is to enhance uptake of services for prevention of mother-to-child transmission of HIV (PMTCT). Using a single pre-post intervention group quasi-experimental design, the study will assess usability, acceptability, and preliminary improvements in stigma and disclosure measures. We will use a mixed method approach (i.e., quantitative and qualitative data collection) to evaluate the intervention. All participants will receive the intervention. The adolescents included in the pilot study will be female, living with HIV, pregnant, unmarried, ages 15-19 years old and include both rural and urban youth. There will be three contacts with study participants. At the first contact, all participants will be consented and complete a baseline quantitative survey. At the second contact, participants will receive a one-on-one intervention session. During the intervention session, they will be provided with a mobile phone with internet access, guided on how to access the digital intervention, receive a guided tour of the website, and have their questions answered. After the tour, they will be asked to explore the website and complete specific tasks without research staff assistance (e.g., to actively engage with selected modules). While exploring the website, participants will be asked to "think aloud" and share thoughts and questions as they arise. These qualitative data of participants' thoughts during the session will be audio recorded and field staff notes will be written. On completion of the intervention tasks, participants will return the mobile phone to the research staff and complete a quantitative survey assessing the intervention's acceptability and usability. At the third contact, two weeks after the intervention session, we will collect follow up survey data to assess maintenance/persistence of intervention effects after a short duration exposure. Survey measures at baseline and two-week follow up will include demographics, stigma about HIV and pregnancy, disclosure self-efficacy for HIV and pregnancy, and disclosure of HIV and pregnancy to caregivers. Descriptive analyses will be conducted of the quantitative data to describe time-related patterns and assess clinically meaningful improvements in our measures.
