简要总结
This study evaluates the effect of one new form of introduction language and three new modes of providing consent on interactive voice response (IVR) survey cooperation, response, refusal and contact rates, as compared to control group, in Colombia and Uganda.
详细描述
Using random digit dialing (RDD) sampling technique, RDD participants will be randomized to one of five introduction and consent combinations and then have them complete noncommunicable disease risk factor survey with an additional module regarding their understanding of the survey and of its voluntariness. This mobile phone survey will be sent as an interactive voice response (IVR). In IVR surveys, participants use their touch tone key pad to answer pre-recorded questions.
