This paper reports the results of a randomized controlled trial (RCT) to assess the efficacy of Nexus , a telehealth delivered intervention that combines Couples’ HIV counseling and testing (CHTC) with home-based HIV-testing, examining the impact of the intervention on the couples’ formation and adherence to safer sexual agreements. Between 2016 and 2018, 424 couples were recruited online from the U.S and randomized to the intervention arm (a telehealth delivered CHTC session with two home HIV-testing kits) or a control arm (two home HIV-testing kits), with study assessments at baseline, 3 and 6 months. Outcomes were the formation and adherence to safer sexual agreements, dyadic discordance in sexual agreements, breakage of sexual agreements, and perceptions of PrEP. Couples in the intervention arm had significantly greater odds of reporting a safer sexual agreement (3 months OR 1.87, p-value 0.005, and 6 months OR 1.84, p-value 0.007), lower odds of reporting discordant sexual agreements at 6 months (OR 0.62, p-value 0.048), and a significantly lower odds of reporting breaking their sexual agreement (3 months OR 0.51, p-value 0.035, and 6 months OR 0.23, p-value 0.000). By 6 months, couples in the intervention arm were less likely to say PrEP was beneficial to one (RRR 0.33, P = 0.000) or both of them (RRR 0.29, P = 0.000) than being beneficial to neither of the partners. The high levels of acceptability and efficacy of the intervention demonstrate strong potential for the scale-up of this efficacious intervention that is delivered through a low-cost telehealth platform.
