Duo Partnership Adherence Commitment Therapy

The investigators will test the intervention to improve HIV care engagement by enrolling 150
sexual or gender minority couples and randomizing 75 couples each to one of two conditions:
1) DuoPACT, a newly-developed couples intervention; or 2) LifeSteps, a standardized
antiretroviral adherence intervention for HIV+ individuals. After randomization, intervention
sessions will be delivered weekly (6 DuoPACT sessions, or 3 Life Steps sessions). All couples
will be assessed pre/post intervention to evaluate intervention effects via behavioral
indicators of engagement in HIV care, the couple's relationship dynamics, and the primary
outcome of HIV viral load.
