Comparison of SMS, IVR, and CATI Surveys in Colombia

Not Applicable

Completed

• Conditions: Noncommunicable Diseases; Surveys and Questionnaires
• Interventions: Other: CATI Survey; Other: SMS Survey; Other: IVR Survey

• Registration Number: NCT04506931
• Lead Sponsor: Johns Hopkins Bloomberg School of Public Health

Brief Summary

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

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Cooperation Rate #1	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.
Response Rate #4	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

Secondary Outcome Measures

Name	Time	Method
Refusal Rate #2	Through study completion, an average of one month	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
Contact Rate #2	Through study completion, an average of one month	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
