Summary

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

Detailed description

Using random digit dialing (RDD) sampling technologies, participants were randomized to one of three airtime incentive structures 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. (i.e. if you are male, press 1; if you are female, press 2). This study is being conducted in both Bangladesh and Uganda.
