Outcome Measures
Primary Outcomes (16)
Intervention Acceptability: System Usability Score (SUS)
The SUS is a 10-item, 5-point Likert scale for evaluating subjective usability. Each item is scored from 1 to 5, with the calculation involving either subtracting 1 from the user response or the user response from 5 depending on the item. The scores are then summed and multiplied by 2.5 to obtain a total score ranging from 0 to 100. A score above 80 indicates that the intervention is acceptable.
Month 3, Month 6
Intervention Acceptability: Exit Interview
Participants will be asked about their experiences using mHC and FRESH content and potential improvements.
Month 3
Intervention Feasibility: Participant retention
Participant retention rate of over 85% at 6-month follow-up will be the minimum criterion for feasibility.
Baseline through Month 6
Intervention Feasibility: Number of FRESH sessions viewed
Intervention feasibility will be evaluated by the total number of FRESH sessions viewed.
Baseline through Month 6
Intervention Feasibility: Number of mHC sessions completed
Intervention feasibility will be evaluated by the number of completed intervention sessions.
Baseline through Month 6
PrEP Uptake: Self-report
PrEP uptake will be assessed using a self-report measure and confirmed via chart review and pharmacy records.
Month 3, Month 6
PrEP Adherence: Visual analog scale
PrEP adherence will be assessed through the Young Adult Adherence Interview, which contains a visual analog scale (VAS) ranging from 0 to 100. Higher percentages on the VAS indicate greater adherence to ART.
Baseline, Month 3, and Month 6
PrEP Adherence: Self-Reported Adherence
PrEP adherence will be evaluated through self-reported adherence over the past four weeks. Participants will rate their adherence on a scale ranging from 0 to 100%, with higher percentages indicating better adherence to PrEP. The result will be triangulated with DBS reports.
Baseline, Month 3, and Month 6
PrEP Adherence: DBS testing
PrEP adherence will be evaluated by tenofovir concentrations in dried blood spots (DBS). The result will be triangulated with self-reports.
Baseline, Month 3, and Month 6
HIV testing uptake: Self-report
HIV testing uptake will be assessed via self-report and confirmed through chart review.
Baseline, Month 3, and Month 6
Intersectional stigma
Intersectional stigma will be assessed using the Intersectional Discrimination Index, which includes three subsets: anticipated, day-to-day, and major discrimination. The anticipated and day-to-day discrimination measures each consist of 9 items, while the major discrimination measure includes 13 items. The anticipated discrimination score is calculated as a mean ranging from 0 to 4. The day-to-day discrimination score is based on frequency and can range from 0-9 (lifetime) or 0-18 (past-year). The major discrimination score is based on frequency and can range from 0-26 (lifetime) or 0-13 (past-year). For all three measures, higher scores indicate a greater level of anticipated discrimination or experienced discrimination.
Baseline, Month 3, and Month 6
Internalized stigma
Internalized stigma will be evaluated using the Internalized AIDS-related Stigma Scale, a 6-item scale. Scores range from 0 to 6, with higher scores indicating greater internalized stigma.
Baseline, Month 3, and Month 6
Perceived stigma
Perceived stigma will be evaluated using a 13-item, 4-point Likert scale, with a maximum score of 52. Higher scores indicate a higher level of perceived stigma.
Baseline, Month 3, and Month 6
Anticipated stigma
Anticipated stigma will be evaluated from three different sources (friends and family, neighbors, and others in the community, and healthcare workers) using a 9-item, 5-Likert scale. Scores can reach up to 45, with higher scores indicating a greater expectation of experiencing stigma in the future.
Baseline, Month 3, and Month 6
Enacted stigma
Enacted stigma will be evaluated with an 8-item, 4-point Likert scale enacted stigma scale. The total score can reach up to 32, with higher scores indicating having more stigma experiences.
Baseline, Month 3, and Month 6
PrEP stigma
PrEP stigma will be evaluated with a 10-item, 5-point Likert scale. Higher scores indicate a higher level of perceived stigma surrounding PrEP.
Baseline, Month 3, and Month 6

Study Arms (4)
Standard PrEP counseling, mHC, and FRESH content
EXPERIMENTALParticipants in this arm will receive standard PrEP counseling, followed by four mHC sessions and six FRESH sessions to reduce stigma and increase utilization of HIV prevention services.

EXPERIMENTALParticipants in this arm will receive the standard PrEP counseling.
Interventions
mHC is a four-session, 20-minute, motivational interviewing-based intervention, which will be delivered on the CIAS platform. It will be tailored to participants' responses given during the interaction in the intervention. In the first two sessions, the (virtual) counselor will motivate participants to overcome stigma and utilize HIV prevention services by using tailored motivational interviewing strategies, develop an individualized change goal based on their readiness, and provide cognitive behavioral strategies. In the last two sessions, the counselor will review the change plan, monitor progress, and provide support for sustained behavioral change. The sessions will occur within three months after baseline.
FRESH content includes six 10-15 minute sessions with interactive, culturally sensitive multimedia modules, which will be delivered on the CIAS platform. The content will aim to improve self-efficacy, reduce intersectional stigmas and promote HIV preventative behaviors. The sessions will occur within three months after baseline.
All participants will receive one-on-one, face to face counseling from focusing on sexual and behavioral risk assessment for HIV/STIs, risk reduction, and HIV prevention. For those not on PrEP, the sessions will focus on risk perception, awareness of PrEP, and facilitators and barriers to PrEP access. For those on PrEP, the sessions will focus on adherence. The counseling will be provided at baseline, 3 months, and 6 months.
