Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cooperation Rate #1	As defined by American Association for Public Opinion Research, cooperation rate is defined as I/(I+P+R) where I is complete interviews, P is partial interviews, R is refusals and breakoffs	Through study completion, an average of one month
Primary	Response Rate #4	As defined by American Association for Public Opinion Research, response rate is defined as (I+P)/ (I+P+R+eU) where I is complete interview, P is partial interview, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns	Through study completion, an average of one month
Secondary	Refusal Rate #2	As defined by American Association for Public Opinion Research, refusal rate is defined as R/(I+P+R+eU) where R is refusals and breakoffs, I is complete interview, P is partial interview, and eU is the estimated eligible proportion of unknowns	Through study completion, an average of one month
Secondary	Contact Rate #2	As defined by American Association for Public Opinion Research, contact rate is defined as (I+P+R)/ (I+P+R+eU) where I is complete interview, P is partial interview, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns	Through study completion, an average of one month
