Brief summary

The case for mobile health (mHealth) has been gaining traction as a source to improve health outcomes of individuals. mHealth refers to the use of Information and Communication Technologies (ICT) to support health care. The ubiquity and penetration of mobile phones presents the opportunity to deliver health care services directly to citizens, with the greatest potential gains in under-resourced health ecosystems. Operating for 8 years and currently supporting 1.28 million mothers through their pregnancies and early childhood care, MomConnect represents one of the largest maternal health messaging platforms in the world. Implemented at the national level, MomConnect has been credited with being the first national-scale mHealth program of its kind and has won numerous international awards. As a WhatsApp-delivered service, MomConnect has been limited by WhatsApp's historical terms of service. In its current form, MomConnect can only start a conversation with mothers once a week by alerting them of their upcoming antenatal care (ANC) appointment. Recent changes to WhatsApp's terms of service have removed the restriction around push messages for certain programs, including MomConnect. Messages have historically been restricted to weekly conversation starters and carry only generic administrative reminder-style information. As a result, it is possible that many mothers are failing to engage with the content as much as they could. If mothers were more engaged, it could greatly increase exposure and knowledge of reducing the total number of mothers exposed to critical maternal and infant health content. With the updated terms of service, there is an opportunity to test different ways of engaging mothers. This study proposes to evaluate, through a randomized controlled trial (RCT), the relative effect of three new behaviorally-informed program models on key knowledge of and adoption of healthy behaviors.

Interventions

BEHAVIORALQuality-Based Digital Messaging

The impact of MomConnect's models will be evaluated using a randomized controlled trial (RCT). Randomization will be at the individual level, where an individual refers to the unique user, which is defined by the unique phone number used at the time of registration to MomConnect at health facilities. Randomizing control and treatment allocations ensures that the study groups will be comparable in terms of observable and unobservable characteristics in expectation. Therefore, statistical inference can shed light on the likelihood that any differences in outcome variables at the end of the intervention were caused by the intervention as compared to chance. We will also study the treatment effects on different outcomes between the different arms of the experiment - comparing outcomes across different treatment arms or outcomes in the control to outcomes in treatment arms will help us answer the aforementioned research questions.
