Brief summary
People using HIV self-testing (HIVST) need access to quality HIV-prevention programming, including education and exploration of pre-exposure prophylaxis (PrEP) - an effective biomedical prevention tool that continues to expand in choices and access points in the US. HIVST and PrEP are both central to ending the HIV epidemic, but presently they are not linked together in a systematic way. To address the critical need for PrEP programming to accompany HIV self-testing (HIVST), our study will work with experts and HIVST users to develop and pilot a novel, interactive, mobile friendly PrEP decisional-aid mobile optimized website that helps to raise awareness around PrEP and guides people through a PrEP-decision-making process that matches their needs and values, and links people to resources for local or online PrEP. This PrEP Decisional Aid to accompany Self HIV-test kits (the DASH app) will be in a randomized controlled pilot trial with 120-170 HIV self-test kit users in the CDC's Together TakeMeHome HIV-test kit dissemination program. PrEP uptake at 3-months (primary outcome) will be compared between arms descriptively and with logistic regression models. Change in additional PrEP related factors (knowledge, stigma, decisional conflict, barriers and facilitators) will be assessed as secondary outcomes. Implementation metrics, acceptability and feasibility will also be evaluated quantitatively and qualitatively. Results will inform revisions and recommendations for a decisional aid for raising PrEP awareness and use among self HIV-test users.
Detailed description
This mixed methods intervention development and implementation hybrid (type 1) study will pilot a self-administered PrEP Decisional Aid for dissemination with Self-administered HIV test kits (DASH). Recruiting from Together TakeMeHome (TTMH) HIVST kit recipients, the proposed pilot has 3 specific aims. The first aim was to develop the PrEP decisional aid for dissemination with self-administered HIV test kits (DASH) through iterative expert and community consultation. AIM 2- Pilot DASH with TTMH HIVST kit recipients and determine direction and magnitude of impact on PrEP awareness, intentions and starts. HIVST recipients from TTMH will be recruited into a 3-month pilot completing online surveys assessing PrEP awareness, knowledge, intentions, and use at baseline, and 1- and 3-month follow-up. Participants randomly assigned to the DASH arm, versus the measures-only arm, receive the DASH link post baseline. A minimum of 120 and maximum of 170 (to reach 60 intervention arm participants who complete 1 full session of the DASH app) will be enrolled. PrEP uptake at 3-months (primary outcome) will be compared between arms descriptively and with logistic regression models (both intent to treat and as-treated). Change in additional PrEP related factors (knowledge, stigma, decisional conflict, barriers and facilitators) will be assessed as secondary outcomes. Longitudinal growth modelling will be used to analyze over-time data between study arms. H2: DASH arm participants will have more self-reported PrEP starts (primary) by 3 months than those in the comparison condition. H3: DASH arm participants will report more favorable secondary outcomes on follow-up surveys. AIM 3- Conduct mixed methods evaluation of acceptability, feasibility and experiences with the DASH. All participants will complete a brief survey on acceptability of the PrEP-related resources received (DASH or standard for what is locally available). Patterns of utilization of DASH components, including use of links to PrEP services, will be summarized. Qualitative virtual in-depth interviews with 30 participants (20 DASH, 10 control) will explore nuanced aspects of PrEP decision making and expand on the quantitative data. H4: DASH will be evaluated as acceptable and feasible.
Interventions
BEHAVIORALPrEP Decisional Aid for dissemination with Self-administered HIV test kits (DASH)
Participants assigned to the intervention arm will be provided with a unique code to access the login for the DASH app. The app provides a PrEP information, explores values and decisions around PrEP, and leads participants through an exploration of their PrEP decisions with links to PrEP resources (local and online) for those interested in findings out more about or starting PrEP. Participants are asked to complete one complete session and return back to the app at any time during their participation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| PrEP Start | 3 months | Self-reported PrEP initiation determined by a single item asking "Are you currently using PrEP?" \[Yes/No\] |
| Theoretical Framework of Acceptability Scale for DASH | Month 1 and month 3 | Adapted from the Theoretical Framework of Acceptability Scale. 9 items assess affective attitudes, burden, perceived effectiveness, intervention coherence, opportunity costs, self-efficacy and ethicality- with likert scale of 1 to 5. A total acceptability score can be calculated by summing responses to items producing a range of 9 to 45 with higher scores reflecting higher overall acceptability. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| PrEP Information | Baseline, Month 1 and Month 3 | Accurate information about PrEP is assessed using using 10 items stated- 5 states as self-ratings of information (I know...) and 5 as facts with answer options of True, False, Not sure/don't know. Scores are summed across all items with a range of 0 (no perceived knowledge and none correct) to 10 (true to all perceived knowledge questions and correct on all factual items). Higher scores reflect higher knowledge/information accuracy about PrEP. Outcomes use baseline to determine gains in knowledge over time. |
| Movement on PrEP Care Continuum | Baseline, Month 1 and Month 3 | Movement through the PrEP continuum of care is calculated at month 1 and month 3. Participants are characterized as not interested in PrEP, interested in PrEP, spoke with a navigator about PrEP since starting the DASH project, spoke with a provider about PrEP since starting the DASH project, or started PrEP. Movement is identified by determing if the participant has made forward movement in this process or has maintained being on PrEP between month 1 and month 3 surveys. Stage is ordinal and descriptive. |
