This is a formative study, designed to provide information required to tailor Life-Steps for Pre-Exposure Prophylaxis (PrEP), an evidence-based cognitive behavioral adherence intervention, to enhance PrEP uptake and adherence in high risk young men who have sex with men (YMSM) and young transgender women who have sex with men (YTWSM).
Life-Steps for Pre-exposure prophylaxis (PrEP) is a manualized modular adherence intervention based on principles of cognitive-behavioral therapy (CBT), that allows for recipients of the intervention to focus on the greatest challenges that they perceive in maintaining optimal adherence to PrEP.

To adapt Life-Steps for Pre-Exposure Prophylaxis (PrEP) to be culturally relevant and appropriate for at-risk young men who have sex with men (YMSM) and transgender women who have sex with men (TWSM). The investigators will conduct in-depth qualitative interviews with up to 20 HIV-uninfected, at risk YMSM/TWSM at Fenway Health, an Adolescent Trials Network (ATN) clinical center. The investigators will also conduct in-depth, individual qualitative interviews with up to 10 key informants, including PrEP providers and staff at community-based organizations that work with YMSM/TWSM. Through these interviews, perceived facilitators and barriers to initiating and adhering to PrEP will be identified, and potential strategies to optimize adherence to PrEP for YMSM/TWSM. The investigators will explore youth perspectives on the use of nurses to deliver health messages and weekly text messages. YMSM/TWSM will be recruited at various points in the PrEP continuum of care, including those have opted not to initiate PrEP despite recommendations from clinicians, those who are using PrEP who report high levels of adherence and those who report adherence challenges through clinician referrals and direct recruitment in clinic waiting areas. Interviews will last approximately 60 minutes and will be digitally-recorded. Recordings will be transcribed and analyzed rapidly to inform the design of the youth-tailored Life-Steps for PrEP for YMSM/TWSM that we will test in Aim 2.
To conduct a 2-arm pilot randomized control trial (RCT) to assess feasibility and acceptability of the Life-Steps for PrEP for youth intervention and preliminary efficacy of the intervention to improve PrEP adherence and retention in PrEP care compared to the standard of PrEP care at three different clinical sites. Investigators will enroll 50 YMSM/TWSM in the RCT (randomized 1:1 to the 2 arms) across the 3 sites. The primary efficacy outcomes will be PrEP adherence-as measured by dried blood spot testing -and retention in PrEP care-as measured by attendance at quarterly clinic appointments-at 3 and 6 months post baseline. Secondary outcomes include changes in sexual behaviors, retention in prevention services, and acceptability of the interventions which will be assessed at each major visit. Investigators will also conduct a brief, 15-minute semi-structured exit interview with participants in the Life-Steps for PrEP for youth intervention arm to provide an opportunity for more in-depth (open-ended) feedback on intervention satisfaction and acceptability. These data will be used to finalize the intervention manual to enhance participant acceptability.

Experimental: Life Steps for PrEP for Youth
Life Steps for PrEP for Youth was derived from our prior PrEP work supported by the National Institute of Mental Health and will be tailored for YMSM/TWSM based on the findings from 20 qualitative interviews with YMSM and TWSM and 10 qualitative interviews with key informants. It will likely consist of four weekly sessions at the time of PrEP initiation and two booster sessions, which occur two and three months after PrEP initiation. Overall, the core components of the intervention will focus on medication adherence, sexual behavior, and problem solving barriers to adherence, using motivational interviewing when needed.
Behavioral: Life Steps for PrEP for Youth
Life-Steps is a modular adherence intervention based on principles of cognitive-behavioral therapy (CBT), that allows for recipients of the intervention to focus on the greatest challenges that they perceive in maintaining optimal adherence to pre-exposure prophylaxis.
No Intervention: Standard of Care
After being prescribed PrEP, participants will receive standard-of-care adherence support for PrEP. They will have blood collected for medication adherence measures and will complete computer assisted behavioral surveys during study visits. Participants in this arm will also be followed for 6 months.
- Pre-Exposure Prophylaxis (PrEP) Adherence at 3 months post PrEP initiation [ Time Frame: Blood sample collected at 3 month visit post baseline ]Measured by dried blood spot (DBS) testing of tenofovir diphosphate (TFV-DP) and emtricitabine triphosphate (FTC-TP)
- Pre-Exposure Prophylaxis (PrEP) Adherence at 6 months post PrEP initiation [ Time Frame: blood sample collected at 6 month visit post baseline ]Measured by dried blood spot (DBS) testing of tenofovir diphosphate (TFV-DP) and emtricitabine triphosphate (FTC-TP)
- Retention in Pre-Exposure Prophylaxis (PrEP) care and prevention services [ Time Frame: Records will be abstracted at the end of the study period for each participant to determine if they attended a clinic appointment at 3 and 6 months post baseline ]Attendance at quarterly clinic appointments obtained through medical record abstraction
- LifeSteps for PrEP for Youth Intervention Acceptability [ Time Frame: Measured at each study visit (3 and 6 months post baseline) ]To measure acceptability, participants will be asked to self-report the degree to which they find the intervention appropriate and useful using Likert-type agreement scales.
- LifeSteps for PrEP for Youth Intervention Satisfaction [ Time Frame: Measured at each study visit (3 and 6 months post baseline) ]
Satisfaction will be measured with the Client Satisfaction Questionnaire (CSQ-8). The CSQ-8 is an 8-item, easily scored and administered measurement designed to measure client satisfaction with services.
The CSQ-8 has been extensively studied, and while it is not necessarily a measure of a client's perceptions of gain from treatment, or outcome, it does elicit the client's perspective on the value of services received. The CSQ-8 seems to operate about the same across all ethnic groups.
The CSQ-8 is scored by summing the item scores to produce a range of 8 to 32, with high scores indicating greater satisfaction.

- Adapt Life-Steps for PrEP to be appropriate for at-risk young men who have sex with men (YMSM) and young transgender women who have sex with men (YTWSM) [ Time Frame: one time qualitative interviews will be conducted ]Study Investigators will conduct qualitative interviews with up to 20 HIV-uninfected YMSM/TWSM at Fenway Health and with up to 10 key informants, including PrEP providers and staff at community-based organizations that work with YMSM/TWSM. Interviews will be transcribed and analyzed using content analysis to identify changes that should be made to the Life-Steps intervention.
