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.

Conditions

Surveys and Questionnaires; Noncommunicable Diseases

Keywords

mobile phone surveys; interactive voice response; computer-assisted telephone interviews; introduction mode

Outcome Measures

Primary Outcomes (2)

• Cooperation Rate #1

  As defined by American Association for Public Opinion Research, cooperation rate is defined as I/(I+P+R) where I is complete interviews, P is partial interviews, and R is refusals and breakoffs.

  Through study completion, an average of one month

• 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 complete interviews, P is partial interviews, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns

  Through study completion, an average of one month

Secondary Outcomes (2)

• Refusal Rate #2

  Through study completion, an average of one month

• Contact Rate #2

  Through study completion, an average of one month

Study Arms (2)

CATI

EXPERIMENTAL

Introduction and consent via computer assisted telephone interview

Other: CATI

IVR

NO INTERVENTION

Introduction and consent via interactive voice response

Interventions

CATI OTHER

The participants in this arm were read the introduction and asked for consent by a call center employee using computer-assisted telephone interviewing and then were sent a noncommunicable disease risk factor survey via interactive voice response. This mode was used to motivate participants to complete the survey.
