Brief summary
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.
Detailed 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. (i.e. If you are male, press 1; If you are female, press 2). This study was conducted in both Bangladesh and Uganda
Interventions
OTHER1X airtime incentive
an incentive given in the form of airtime to motivate participants to complete the survey. Participants were given 50 Bangladeshi Taka ($0.60 USD) or 5000 Ugandan Shillings (UGX; $1.35 USD as of April 3, 2018) worth of airtime for completing the survey
OTHER2X airtime incentive
an incentive given in the form of airtime to motivate participants to complete the survey. Participants were given 100 Bangladeshi Taka ($1.20 USD) or 10000 UGX ($2.70 USD) worth of airtime for completing the survey

Intervention model description
Participants were randomized to one of three airtime incentive amounts: 1) no incentive; 2) 1X incentive; or 3) 2x incentive where X was equal to 50 Bangladeshi Taka ($0.60 USD) or 5000 Ugandan Shillings (UGX; $1.35 USD as of April 3, 2018). Airtime incentives were sent if participants completed the noncommunicable disease risk factor survey
