Clinical Trial Summary

This study focuses on mechanisms to adapt the performance of interactive voice response (IVR) and short message service (SMS) surveys conducted in low-and middle-income (LMIC) setting (Tanzania) and evaluates how the two survey modalities (IVR and SMS) affect survey metrics, including response, completion and attrition rates.


Description:

Using random digit dialing (RDD) sampling technique, participants will be randomized to one of two arms : 1) IVR or 2) SMS. Participants in the first study arm will receive an IVR survey. Participants in the second study arm will receive a SMS survey. The IVR and SMS questionnaires contain 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.

Outcome

Type Measure Description Time frame Safety issue
Primary Cooperation Rate #1 As defined by American Association for Public Opinion Research, cooperation rate is defined as I/(I+P+R) where I is the number of participants with complete interviews, P is the number of participants with partial interviews, and R is the number of participants with refusals and breakoffs. Through study completion, an average of one month
Primary Response Rate #4 As defined by American Association for Public Opinion Research, response rate is defined as (I+P)/(I+P+R+eU) where I is the number of participants with complete interviews, P is the number of participants with partial interviews, R is the number of participants with refusals and breakoffs, and eU is the estimated eligible proportion of unknowns Through study completion, an average of one month
Secondary Refusal Rate #2 As defined by American Association for Public Opinion Research, refusal rate is defined as (R)/(I+P+R+eU) where R is the number of participants with refusals and breakoffs, I is the number of participants with complete interviews, P is the number of participants with partial interviews, and eU is the estimated eligible proportion of unknowns Through study completion, an average of one month
Secondary Contact Rate #2 As defined by American Association for Public Opinion Research, contact rate is defined as (I+P+R)/(I+P+R+eU) where I is the number of participants with complete interviews, P is the number of participants with partial interviews, R is the number of participants with refusals and breakoffs, and eU is the estimated eligible proportion of unknowns Through study completion, an average of one month
