Brief summary

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.

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.
