Completed

• Conditions: Noncommunicable Diseases; Surveys and Questionnaires
• Interventions: Other: 1X airtime incentive; Other: 2X airtime incentive

• Registration Number: NCT03768323

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
