简要总结
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.
详细描述
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.

主要结局
Response Rate #4
时间窗: Through study completion, an average of one month
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
Cooperation Rate #1
时间窗: Through study completion, an average of one month
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
次要结局
- Contact Rate #2(Through study completion, an average of one month)
