  • Abstract: Many people living with HIV in Sub Sahara Africa failed to adhere to free Anti-retroviral Therapy (ART), the medical treatment for HIV that can stop the virus from progressing and transmitting. This paper seeks to identify the barriers to treatment adherence. We recruit patients that are new on ART from a large health center in Mozambique and randomly provide interventions to assist them in overcoming the limited attention problem, information imperfection, or social stigma concerns. We track the medication possession ratio (MPR) in six months to evaluate the interventions and benchmark their effects against conditional cash transfers. Moreover, to shed light on the spillovers of the interventions, we offer coupons for the participants to refer their partners to get tested. The experiment result will inform us of behavioral patterns of the population that are economically and physically vulnerable. Effective interventions are ready to be scaled up in HIV-treatment facilities in resource-constrained environments.
