Clinical Trial 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.

Description:

Using random digit dialing (RDD) sampling techniques, participants were randomized to one of two introduction modes, followed by a noncommunicable disease (NCD) risk factor survey. The two modes were computer assisted telephone interview (CATI), in which a call-center employee read the introduction to a participant and received oral consent from them, before sending them the NCD risk factor survey via IVR, or the entire survey, including the introduction and consent, being obtained via 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 Tanzania.

Eligibility

Inclusion Criteria:

• Access to a mobile phone

• Greater or equal to 18 years of age

• In Bangladesh, conversant in either English or Bangla language. In Uganda, conversant in either Luo, Luganda, Runyakitara, or English languages.

Exclusion Criteria:

Related Conditions & MeSH terms

• Noncommunicable Diseases
• Surveys and Questionnaires

Intervention

Other:
• CATI
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.

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 complete interviews, P is partial interviews, and R is 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 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	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.	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 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
