Airtime Incentive Amounts to Improve Interactive Voice Response Surveys in Bangladesh and Uganda

A Randomized Controlled Trial of Varying Airtime Incentive Amounts to Improve Interactive Voice Response (IVR) Survey Performance in Bangladesh and Uganda

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.

Study Overview

• Status: Completed
• Conditions: Noncommunicable Diseases; Surveys and Questionnaires
• Intervention / Treatment: Other: 1X airtime incentive; Other: 2X airtime incentive

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

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
NO_INTERVENTION: Control; No airtime incentive was given for completing the survey
EXPERIMENTAL: 1X incentive; 1X airtime incentive	Other: 1X 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
EXPERIMENTAL: 2X incentive; 2X airtime incentive	Other: 2X 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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cooperation Rate #1	As defined by American Association for Public Opinion Research,the number of complete interviews divided by the sum of complete interviews, partial interviews, refusals, and breakoffs	Through study completion, an average of one month
Response Rate #4	As defined by American Association for Public Opinion Research,the number of complete and partial interviews divided by the sum of complete interviews, partial interviews, refusals, breakoffs, and the estimated eligible proportion of unknowns	Through study completion, an average of one month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Refusal Rate #2	As defined by American Association for Public Opinion Research,the number of refusals and break-offs divided by the number of complete interviews, partial interviews, refusals, breakoffs, and the estimated eligible proportion of unknowns	Through study completion, an average of one month
Contact Rate #2	As defined by American Association for Public Opinion Research,the number of complete and partial interviews, refusals and break-offs divided by the number of complete interviews, partial interviews, refusals, breakoffs, and the estimated eligible proportion of unknowns	Through study completion, an average of one month
