Intervention model description: Participants were randomized to one of two introduction and consent modes: 1) computer-assisted telephone interviews, or 2) interactive voice response.
Primary purpose: OTHER

Brief summary: This study evaluates the effect of two different introduction modes on interactive voice response (IVR) survey cooperation, response, refusal, and contact rates, in Bangladesh and Tanzania.

Detailed description: Using random digit dialing (RDD) sampling techniques, participants were randomized to one of two introduction modes, followed by a noncommunicable disease (NCD) risk factor survey. The two modes were computer assisted telephone interview (CATI), in which a call-center employee read the introduction to a participant and received oral consent from them, before sending them the NCD risk factor survey via IVR, or the entire survey, including the introduction and consent, being obtained via 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 Tanzania.
