| Sumario: | Purpose: This paper reports a review of couple-based behavioral HIV interventions conducted by the Social Intervention Group (SIG); and addresses gaps, future directions, and implications for couple-based HIV interventions. Method: We performed a literature review for SIG research on intervention and prevention studies involving couples/partners. Results: We identified nine couple-based interventions. Outcomes included reduced sexual and substance use-related risk behaviors and improved use of anti-retroviral treatment. We conducted these studies in diverse venues, including needle/syringe exchange programs, primary care clinics, and criminal justice settings. Conclusions: The findings of this review provide strong evidence for the efficacy of couple-based HIV interventions in reducing sexual HIV risks and linkage to HIV and substance-use treatment. SIG has advanced couple-based HIV intervention research science by improving study design, intervention core components, conceptual models, and implementation strategies; which have informed scientific directions and transformed couple-based HIV prevention research.
