The effectiveness of a behavioral science and design intervention for family savings on use of maternal health services and male involvement: study protocol for a randomized controlled trial

BACKGROUND: Lack of financial preparedness for pregnancy can lead to adverse outcomes during childbirth. Behavioral science interventions have been shown to influence savings behavior. Financial savings interventions can be adapted for the purpose of encouraging individuals to save towards maternal healthcare costs. This article describes a protocol to assess the effectiveness of an intervention formulated with a behavioral science approach for encouraging use of maternal health services through increased financial savings for birth preparedness and maternal healthcare costs among pregnant women or their partners in Uganda. METHODS: A randomized controlled trial will be conducted to assess the effectiveness of the intervention among pregnant women or their partners in Uganda’s central region, including the capital of Kampala. Seven hundred pregnant women (12–35 gestational weeks) or their partners will be recruited. All participants will receive access to a committed mobile money health savings account provided by a local organization that also offers savings targets and reminders for antenatal care appointments and health tips as part of a “Mamas Program” offered to expectant mothers. The time period in the intervention is from the day of enrollment until two weeks after the delivery date. The control group will receive the standard Mama Program offering. The intervention group will receive the standard Mama Program offering plus behavioral designs encouraging savings behavior through short-message service (SMS) text messages. The primary outcome is usage of maternal health services measured by level of birth preparedness and delivery at a health facility. Secondary outcomes include male involvement in maternal healthcare, measured by financial support, as well as total savings for healthcare, assessed using the validated amount of savings accrued in participants’ clinicPesa accounts from the day of enrollment plus any withdrawals for healthcare expenditures during the intervention period. DISCUSSION: The study will contribute to a better understanding of the effectiveness of behavioral designs encouraging financial savings during pregnancy into committed mobile money health savings accounts. The study could contribute to demonstrating the effectiveness of savings on birth preparedness, usage of maternal health services, and male involvement in maternal healthcare.
