WYZ: Results of a pilot intervention of a mobile health application for engagement in care and antiretroviral therapy adherence among youth and young adults living with HIV (Preprint)

BACKGROUND Youth are globally recognized as being vulnerable to HIV. Younger age has been correlated with worse health outcomes. Mobile health (mHealth) delivered interventions have the potential to meet youth where they are, using a device they already access. OBJECTIVE Using pre-defined benchmarks, we sought to evaluate the feasibility and acceptability of WYZ, an mHealth application, for improved engagement in care and antiretroviral therapy (ART) adherence among youth and young adults living with HIV (YLWH). WYZ was designed and developed with input from YLWH using a Human-Centered Design approach and based on the Information, Motivation, Behavioral Skills framework to address common barriers to care and ART adherence among YLWH. METHODS We recruited YLWH (18–29 years old) in the San Francisco Bay Area to take part in a six-month pilot trial. Their participation included completing a baseline and exit survey and participating in seven phone check-ins about their use of WYZ. RESULTS YLWH (N= 79) reported high levels of feasibility and acceptability with WYZ use. We met pre-defined benchmarks for recruitment, mean log-ins per week, tracking ART adherence, posting chat topics, and app crashes reported. Ease of app download, install, and set up, as well as comfort with security, privacy, and anonymity were highly rated. Additionally, participants reported high satisfaction for a research project that was remotely conducted. Participants used the app for shorter timeframes compared to the pre-defined benchmarks. CONCLUSIONS We noted high feasibility and acceptability with WYZ. Further research to examine the efficacy of WYZ will enable YLWH and their providers to make informed decisions when using, recommending, and prescribing it for improved engagement in HIV care and ART adherence.

IntroductionYouth and young adults bear a disproportionate share of the HIV burden and there is a critical need for interventions to curb health disparities experienced among these age groups. The purpose of our research is to build on our theory-guided model and formative research to develop a mobile health application, called WYZ, for improved engagement in HIV care and antiretroviral therapy adherence, and pilot test it among youth and young adults living with HIV (YLWH). In this paper, we explain the design and development of WYZ for YLWH, describe the design of a forthcoming pilot trial for evaluating the feasibility and acceptability of WYZ and compare WYZ with other mobile health applications being developed to improve engagement in HIV care and antiretroviral medication adherence.Methods and analysisWe used an agile methodology, shown to be useful in software development, and elicited feedback during beta testing to develop WYZ. WYZ is a modular, adaptive and personalised intervention delivered via a mobile phone. It is grounded in the information, motivation, behaviouralskills model which has been valuable for understanding and guiding the development of interventions for complex health behaviours. WYZ was created in collaboration with YLWH aged 18–29 years using a human-centred design approach that emphasises understanding the perspective of the users of the technology. WYZ is intended to improve engagement in HIV care by: (1) enhancing medication adherence self-efficacy, (2) increasing awareness and use of community resources, (3) reducing barriers to communication between youth and their healthcare team, and (4) providing a secure platform for the formation of a private online community of YLWH. We will conduct a 6-month single-arm pilot study to examine feasibility and acceptability of WYZ among 76 YLWH who live or receive care in the San Francisco Bay Area. All study activities, including recruitment, screening, enrolment, study assessments, provision of incentives and exit interviews, will be conducted remotely. We will explore feasibility and acceptability outcomes of the intervention using quantitative and qualitative methods.Ethics and disseminationStudy staff will obtain written consent for study participation from all participants. This study and its protocols have been approved by the University of California San Francisco (UCSF) Institutional Review Board. Study staff will work with the UCSF Center for AIDS Prevention Studies’ Community Engagement Core and the Youth Advisory Panel to disseminate results to the participants and the community using presentations, community forums, journal publications and/or social media.Trial registration numberNCT03587857; Pre-results.
