Prevention strategies have had limited impact on the trajectory of the HIV/AIDS epidemic. New, innovative approaches to behavioral change are needed to stem the epidemic.
In a joint effort with many colleagues, and in collaboration with the Ifakara Health Institute in Tanzania and, the University of California at Berkeley, we launched a study with the acronym RESPECT (“Rewarding STI Prevention and Control in Tanzania”).
We started with an observation: Conditional cash transfers (CCTs) have been used successfully to promote activities that are beneficial to the participants such as school attendance and health check-ups for children. The Tanzanian experiment asks whether CCTs can be used to prevent people from engaging in activities that are harmful to themselves and others, such as unsafe sex. This is a controversial idea.
