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.

Condition or disease Intervention/treatment Phase
Surveys and Questionnaires Noncommunicable Diseases Other: 1X airtime incentive Other: 2X airtime incentive Not Applicable

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

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 4233 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Participants were randomized to one of three airtime incentive amounts: 1) no incentive; 2) 1X incentive; or 3) 2x incentive where X was equal to 50 Bangladeshi Taka ($0.60 USD) or 5000 Ugandan Shillings (UGX; $1.35 USD as of April 3, 2018). Airtime incentives were sent if participants completed the noncommunicable disease risk factor survey

Official Title: A Randomized Controlled Trial of Varying Airtime Incentive Amounts to Improve Interactive Voice Response (IVR) Survey Performance in Bangladesh and Uganda
Actual Study Start Date : March 26, 2017
Actual Primary Completion Date : July 14, 2017
Actual Study Completion Date : July 14, 2017

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




Primary Outcome Measures :
  1. Cooperation Rate #1 [ Time Frame: Through study completion, an average of one month ]
    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

  2. Response Rate #4 [ Time Frame: Through study completion, an average of one month ]
    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


Secondary Outcome Measures :
  1. Refusal Rate #2 [ Time Frame: Through study completion, an average of one month ]
    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

  2. Contact Rate #2 [ Time Frame: Through study completion, an average of one month ]
    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
