About

This study evaluates the effect of two different airtime incentive amounts on interactive voice response (IVR) survey cooperation, response, refusal, and contact rates, as compared to control group, in Bangladesh and Uganda.

Full description

Using random digit dialing sampling techniques, the investigators randomized random digit dialed (RDD) participants to one of three airtime incentive amounts contingent on them completing the noncommunicable disease risk factor survey. This mobile phone survey was sent as an interactive voice response (IVR). In IVR surveys, participants use their touch tone key pad to answer pre-recorded questions.
