About

The objective of the study is to adapt and assess the feasibility, quality, and validity of short message service or 'text message' (SMS), interactive voice response (IVR), and computer assisted telephone interviews (CATI) for collecting information on noncommunicable disease (NCD) risk factors

Full description

Using random digit dialing (RDD) sampling technique, RDD participants will be randomized to one of the three arms: 1) SMS or 2) IVR or 3) CATI. Participants in the first study arm will receive an SMS survey. Participants in the second study arm will receive a IVR survey. Participants in the third study arm will receive a CATI survey. The IVR, SMS and CATI questionnaires contain a set of demographic questions and one NCD module (alcohol, or tobacco, or diet, or physical activity, or blood pressure and diabetes). The investigators will examine contact, response, refusal and cooperation rates and demographic representativeness by each study arm.
