December 1, 2025 updated by: Abigail Batchelder, Ph.D., M.P.H., Massachusetts General Hospital

Addressing Internalized Stigma and Shame as Barriers to Engagement in HIV Care Among Men Who Have Sex With Men (MSM) With Substance Use Disorders (Project Matter)

This study will implement a pilot randomized controlled trial (RCT, N=60) to assess the feasibility and acceptability a refined emotion regulation intervention designed to improve engagement in HIV-care among substance using HIV+ MSM sub-optimally engaged in HIV care.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Eligible study participants will be screened and enrolled at Fenway Health (Boston, MA). Participants will be randomized to an enhanced treatment as usual (E-TAU) arm or the intervention arm. All participants (in both the E-TAU and intervention groups) will receive a one-session behavioral engagement in care intervention, substance use treatment referral information, and the opportunity to discuss and problem solve barriers to substance use treatment with an interventionist, informed by motivational interviewing principles. After randomization, participants in the intervention group will attend 5 therapy sessions focused on behavioral strategies for improving HIV self-care, meta-cognitive awareness of emotions and thoughts, and cognitive restructuring. All participants will receive texts queries about antiretroviral therapy (ART) adherence and substance use, and participants in the intervention group will also receive text queries about mood. All participants will be compensated for every research visit and completed text message blocks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention
This intervention includes 5 face-to-face therapy sessions with a trained clinician plus a bidirectional text component that queries mood, substance use, and medication adherence.
Behavioral: Project Matter
This intervention includes 5 face-to-face therapy sessions with a trained clinician plus a bidirectional text component that queries mood, substance use, and medication adherence. Both the intervention group and the enhanced treatment as usual (E-TAU) involve a one-session behavioral engagement in care intervention as well as substance use treatment counseling.
Active Comparator: Enhanced Treatment as Usual (E-TAU)
Enhanced treatment as usual includes a one session behavioral engagement in care intervention as well as substance use treatment counseling.
Behavioral: Project Matter
This intervention includes 5 face-to-face therapy sessions with a trained clinician plus a bidirectional text component that queries mood, substance use, and medication adherence. Both the intervention group and the enhanced treatment as usual (E-TAU) involve a one-session behavioral engagement in care intervention as well as substance use treatment counseling.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Acceptability of Intervention
Time Frame: change from baseline to 12 weeks after intervention completion
The summary score of the Client Satisfaction Questionnaire (CSQ-8) (Sum of 8 questions with response options ranging from 1-4).
change from baseline to 12 weeks after intervention completion
Feasibility of Intervention
Time Frame: change from baseline to 12 weeks after intervention completion
Percent of sessions completed (≥70% considered indicative of feasibility) and percent of text messages responded to by participants (≥70% considered indicative of feasibility).
change from baseline to 12 weeks after intervention completion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Engagement in HIV Care
Time Frame: change from baseline to 12 weeks after intervention completion
Summary Score of 6 indicators of HIV treatment engagement: no missed and not rescheduled HIV-related appointments in the past 3 months, no missed and not rescheduled HIV-related lab tests in the past 3 months, maintaining ART prescriptions over the past 3 months, maintaining >=80% ART adherence in the past 30 days, no period of 4 days where ART was stopped in the past 3 months (without guidance from an HIV care provider), and undetectable viral load at the study visit.
