Comparison of SMS and IVR Surveys in Tanzania
April 25, 2022 updated by: Johns Hopkins Bloomberg School of Public Health
Comparison of Short Message Service (SMS) and Interactive Voice Response (IVR) Mobile Phone Surveys for Non-communicable Disease Risk Factor Surveillance in Tanzania
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.

Detailed 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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cooperation Rate #1
Time Frame: Through study completion, an average of one month
|
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
|
Response Rate #4
Time Frame: Through study completion, an average of one month
|
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
