Sociodemographic Characteristics Related to Cell Phone Survey Completion Among Female Phone Owners in Burkina Faso Randomized to IVR or CATI Follow-up Survey
ABSTRACT
Background:
The remarkable growth of cell phone ownership in low- and middle-income countries (LMIC) has generated significant interest in using cell phones for conducting surveys, employing either Computer Assisted Telephone Interviews (CATI) – a live interviewer administering the survey, or Interactive Voice Response (IVR) – an automated survey.
Objective:
The objective of this analysis is to compare, by mode, the sociodemographic characteristics of cell phone owners who completed a follow-up phone survey to those who did not complete the survey.
Methods:
The study draws on a nationally representative sample of women 15-49 years old who reported cell phone ownership during a household survey in Burkina Faso in 2016. Female cell phone owners were randomized to participate in a CATI or a Hybrid IVR follow-up phone survey, 11 months after baseline interviews. Phone survey completion was defined as responding to more than 50% of questions in the phone survey. We investigated sociodemographic characteristic associated with cell phone survey completion using multivariable logistic regression models, stratifying the analysis by survey mode and by directly comparing CATI and Hybrid IVR respondents.
Results:
The 1766 women were called for the phone survey between November 5- 17, 2017. In both the CATI and Hybrid IVR samples, women in urban communities and women with secondary education or higher were more likely to complete the survey compared to their rural and less educated counterparts. Compared directly, women that completed the Hybrid IVR survey had higher odds of secondary education than CATI completers (Odds Ratio: 1.7, 95% Confidence Interval: 1.1 – 2.6).
Conclusions:
In Burkina Faso, CATI is the preferred method of conducting cell phone surveys due to less sample distortion and a higher response rate compared to Hybrid IVR. Clinical Trial: N/A
