Supporting Tailored And Responsive PrEP in Rural North Carolina (STARR-NC)

August 14, 2025 updated by: University of North Carolina, Chapel Hill

Meet me Where I am: A Multilevel Strategy to Increase PrEP Uptake and Persistence in Rural NC

This project consists of two phases to be completed over five years. Phase 1 (Aims 1 and 2) will be completed during Years 1-3 (R61). The Phase 1 study is a randomized trial of a multilevel HIV Pre-Exposure Prophylaxis (PrEP) intervention strategy in rural and peri-urban North Carolina sexually transmitted infection (STI) clinics, with primary outcome of PrEP uptake within 3 months of an index STI clinic visit.

Study Overview

Detailed Description

Participants will be randomized 1:1 to an intervention or control condition. Participants enrolled in the intervention arm will receive a multilevel intervention with three components: a PrEP Navigator to facilitate linkage to PrEP services and completion of applications for health insurance/drug assistance; a Digital Health Intervention (DHI) platform (HealthMpowerment) - a HIPAA-compliant evidence-based DHI that provides interactive educational resources, social support, and tools for developing PrEP behavioral skills and self-efficacy; and referral to Telehealth PrEP services as an option for linking to PrEP care.

Control arm participants will receive the standard PrEP referral services available at the STI clinic setting where they were recruited. They will also receive linkage to a limited version of the DHI, with basic PrEP resources and information.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: STARR NC Intervention Condition

Intervention arm will receive a multilevel intervention with three components: a PrEP Navigator to facilitate linkage to PrEP services and completion of applications for health insurance/drug assistance; a Digital Health Intervention (DHI) platform (HealthMpowerment); and referral to Telehealth PrEP services as an option for linking to PrEP care.

The Intervention Arm version of the DHI includes: Study Timeline and Calendar, publicly-available PrEP locator feature, Dried Blood Spot self-collection kit ordering, Educational Health Resource Center; Interactive skill-building health activities; social support newsfeed/group chat; Ask the Expert anonymous health question and answer; Medication Tracker; Health Behavior Tracker; Gamification features for participant engagement.

Intervention Arm participants will complete baseline and quarterly follow-up assessments.

Intervention Arm participants will complete two Dried Blood Spot self-collection kits at 3 and 6 months.

Trained professional PrEP navigators will connect with intervention arm participants following study onboarding. Primary navigator responsibilities include helping participants engage in PrEP care, assisting with completing necessary paperwork for insurance, referral to PrEP care, and application for drug assistance programs, as needed. Navigation services will be available to participants for the first 6 months of participation (active intervention period). Navigation services are tailored to the individual needs of each intervention arm participant
PrEP Navigators can link interested intervention arm participants to telehealth PrEP services via self-referral. The study facilitates referral for intervention arm participants to pre-existing telehealth PrEP services. The telehealth PrEP services participants receive are not provided, financed, or staffed by the study. Participants will receive telehealth PrEP services via the technology platform or service that the provider typically employs. PrEP clinical eligibility, visit frequency, monitoring labs, and all other PrEP management will be at the discretion of the established PrEP provider. PrEP navigators can assist with appointment scheduling, reminders, and other provider-access issues, as requested, for the first 6 months of study participation.
The Enhanced version of the HealthMpowerment Digital Health Intervention includes all features from the Basic version, plus the following additional features: Interactive skill-building health activities; social support newsfeed/group chat; Ask the Expert anonymous health question and answer; Medication Tracker; Health Behavior Tracker; Gamification features for participant engagement.
Active Comparator: STARR NC Standard-of-Care Control Condition

Standard-of-Care Control arm will receive the standard PrEP referral services available at the STI clinic setting where they were recruited. They will also receive study staff guided support to install the control arm version of the HealthMPowerment DHI platform.

The Control Arm version of the DHI includes: Study Timeline and Calendar, publicly-available PrEP locator feature, Dried Blood Spot self-collection kit ordering, Educational Health Resource Center.

Control Arm participants will complete baseline and quarterly follow-up assessments.

Control Arm participants will complete two Dried Blood Spot self-collection kits at 3 and 6 months.

The Control Arm version of the HealthMpowerment Digital Health Intervention includes: Study Timeline and Calendar, publicly-available PrEP locator feature, Dried Blood Spot self-collection kit ordering, Educational Health Resource Center.

Average Self-reported Score on the PrEP Stigma Scale at 3 Months
Time Frame: 3 months

Average self-reported score on the PrEP Anticipated Stigma Scale as reported on the computer-assisted self-interview (CASI) at 3 months

The mean composite score is calculated from the PrEP Anticipated Stigma Scale (Calabrese et al., 2018), an 8-item validated scale measuring the sub-constructs of PrEP user stereotypes and PrEP disapproval by others. Item response options include: (1) Strongly Disagree, (2) Disagree, (3) Agree, (4) Strongly Agree. Mean scores are calculated, with higher scores indicating stronger perceived PrEP stigma. Total possible composite score ranges from 8 (lowest stigma, best outcome) to 32 (highest stigma, worst outcome).
