About this study

Official title: A Randomized Controlled Trial of Narrative Voice and Introduction Content to Improve Interactive Voice Response (IVR) Survey Performance in Bangladesh and Uganda

This study evaluates the effect of two different narrative voices (one male and one female) and two different introductions (one with informational content and the other with additional motivational content) on interactive voice response (IVR) survey cooperation, response, refusal, and contact rates, as compared to a control group (male, informational), in Bangladesh and Uganda.

Read the detailed description

Using random digit dialing (RDD) sampling techniques, participants were randomized to one of four arms: 1) male narrator and informational survey introduction, 2) male narrator and motivational survey introduction, 3) female narrator and informational survey introduction, and 4) female narrator and motivational survey introduction,male motivational, female informational, female motivational) which were then followed by a noncommunicable disease risk factor survey. This mobile phone survey was sent as an interactive voice response (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 Uganda.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    Measured: Through study completion, an average of one month

  2. 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.

    Measured: Through study completion, an average of one month

Secondary outcomes (2)

  1. 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 refusals and breakoffs, I is complete interviews, P is partial interviews, and eU is the estimated eligible proportion of unknowns

    Measured: Through study completion, an average of one month

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

    Measured: Through study completion, an average of one month
