About this study

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

Treatment and study plan

1X airtime incentive

Other

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

2X airtime incentive

Other

Primary outcomes

  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 outcomes

  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
