Clinical Trial Summary

This study evaluates the effect of two different narrative voices (one male and one female) and two different introductions (one with informational content and the other with additional motivational content) on interactive voice response (IVR) survey cooperation, response, refusal, and contact rates, as compared to a control group (male, informational), in Bangladesh and Uganda.

Description:

Using random digit dialing (RDD) sampling techniques, participants were randomized to one of four arms: 1) male narrator and informational survey introduction, 2) male narrator and motivational survey introduction, 3) female narrator and informational survey introduction, and 4) female narrator and motivational survey introduction,male motivational, female informational, female motivational) which were then followed by a 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.
