Brief summary: This study focuses on mechanisms to adapt the performance of interactive voice response (IVR) and computer assisted telephone interviews (CATI) surveys conducted in low-and middle-income (LMIC) setting (Bangladesh) and evaluates how the two survey modalities (IVR and CATI) affect survey metrics, including response, completion and attrition rates.

Detailed description: Using random digit dialing (RDD) sampling technique, participants will be randomized to one of two arms : 1) IVR or 2) CATI. Participants in the first study arm will receive an IVR survey. Participants in the second study arm will receive a CATI survey. Each questionnaire contains a set of demographic questions and one non-communicable disease (NCD) module (alcohol, or tobacco, or diet, or physical activity, or blood pressure and diabetes). We will examine contact, response, refusal and cooperation rates and demographic representativeness by each study arm.

Eligibility criteria: Inclusion Criteria:
