Given the many resources needed for robust implementation of DHS, alternative data collection methodologies are warranted. Interviewer training and supervision is time-intensive and requires ongoing quality assurance efforts. They require door-to-door in-person interviews, suitable transportation for poor roads, and multiple attempts to reach selected households. Yet, DHS are time-consuming and expensive. DHS surveys have large, nationally representative samples that are generated through household interviews. Implemented in more than 90 countries, standard DHS are repeated in many countries every 3–6 years to assess a range of monitoring and evaluation indicators of population, health, and nutrition. VOTO Mobile or its staff did not provide any funding for this study.Īmerican Association of Public Opinion Research C4H,ĭemographic and health survey (DHS) programs have been relied on to assess population health in low and middle income countries (LMIC) since 1984. VOTO Mobile was contracted to perform work and services necessary to support activities on the project survey. To do this VOTO provides a software platform, interconnections with Mobile Network Operators, implementation staff and advisory services. VOTO runs the end-to-end implementation of these surveys such that a researcher can provide a survey script and methodology and VOTO will return the results. VOTO Mobile works in the field of mobile phone surveys by enabling IVR and SMS data collection. This does not alter our adherence to PLOS ONE policies on sharing data and materials. VOTO Mobile provided the survey platform for study data collection.
