Evaluation of Mechanisms to Improve Performance of Mobile Phone Surveys in Low- and Middle-Income Countries: Research Protocol

Abstract

BackgroundMobile phone ownership and access have increased rapidly across low- and middle-income countries (LMICs) within the last decade. Concomitantly, LMICs are experiencing demographic and epidemiologic transitions, where non-communicable diseases (NCDs) are increasingly becoming leading causes of morbidity and mortality. Mobile phone surveys could aid data collection for prevention and control of these NCDs but limited evidence of their feasibility exists.ObjectiveThe objective of this paper is to describe a series of sub-studies aimed at optimizing the delivery of interactive voice response (IVR) and computer-assisted telephone interviews (CATI) for NCD risk factor data collection in LMICs. These sub-studies are designed to assess the effect of factors such as airtime incentive timing, amount, and structure, survey introduction characteristics, different sampling frames, and survey modality on key survey metrics, such as survey response, completion, and attrition rates.MethodsIn a series of sub-studies, participants will be randomly assigned to receive different airtime incentive amounts (eg, 10 minutes of airtime versus 20 minutes of airtime), different incentive delivery timings (airtime delivered before survey begins versus delivery upon completion of survey), different survey introductions (informational versus motivational), different narrative voices (male versus female), and different sampling frames (random digit dialing versus mobile network operator-provided numbers) to examine which study arms will yield the highest response and completion rates. Furthermore, response and completion rates and the inter-modal reliability of the IVR and CATI delivery methods will be compared.ResultsResearch activities are expected to be completed in Bangladesh, Tanzania, and Uganda in 2017.ConclusionsThis is one of the first studies to examine the feasibility of using IVR and CATI for systematic collection of NCD risk factor information in LMICs. Our findings will inform the future design and implementation of mobile phone surveys in LMICs.

Adaptation of a mobile phone health survey for risk factors for noncommunicable diseases in Colombia: a qualitative study

“…This paper presents the qualitative results of a larger study [19] that used a sequential multimodal exploratory design (QUAL → QUAN), in which an initial phase of qualitative data collection and analysis is developed, followed by another where quantitative data are collected and analyzed [20,21]. The purpose of this design is to adapt and test a standardized MPS instrument in the specific context where it will be applied and obtain generalizable and replicable results in subsequent studies [21].…”

Effect of airtime incentives on response and cooperation rates in non-communicable disease interactive voice response surveys: randomised controlled trials in Bangladesh and Uganda

“…A detailed description of the methods and protocol has been reported 21. The trials are registered with ClinicalTrials.gov, number NCT03768323.…”

“…In 2015, experts in NCDs, mobile health and survey methodology selected questions from standardised surveys such as WHO STEPS and Tobacco Questions for Surveys to be included in the IVR survey 21. The initial questionnaire was tested at Johns Hopkins University for cognitive understanding and usability of the IVR platform with people who identified as being from an LMIC 26.…”

Comparability of modern contraceptive use estimates between a face-to-face survey and a cellphone survey among women in Burkina Faso

“…SSA is expected to reach 50% mobile phone penetration, or the percent of unique mobile phone users within a specific population, in 2021 and 52% penetration by 2025 [6,8]. In this context, demographers are considering the use of cell phone surveys to track national health indicators [9][10][11]. However, phone survey estimates need to be compared with FTF results before substituting data collection modes, to ensure phone survey estimates are valid.…”
