Brief 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.

Conditions

Surveys and Questionnaires; Noncommunicable Diseases

Keywords

mobile phone surveys; interactive voice response; incentive

Outcome Measures

Primary Outcomes (2)

• 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

• 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 Outcomes (2)

• Refusal Rate #2

  Through study completion, an average of one month

• Contact Rate #2

  Through study completion, an average of one month

Model Details: Participants were randomized to one of three airtime incentive structures: 1) no incentive; 2) a fixed 1X incentive for all participants who completed the noncommunicable disease risk factor survey; or 3) a lottery incentive (10-20 times larger than the fixed incentive) given to 1 out of every 20 participants who completed the same survey.
