This is a randomised controlled trial to test the impact of a modified e-coupon service, delivered through SMS, on uptake of sexual and reproductive health services among women calling a free hotline in Uganda.

The overall goal of the proposed research project is to increase uptake of sexual and reproductive health (SRH) services among clients who call into Marie Stopes Uganda's free hotline. The study seeks to achieve this goal by using behavioural economics to design interventions to increase redemptions of e-coupons distributed to hotline clients. The intervention will include modifying the text message sent to e-coupon recipients as well as sending follow-up texts reminding clients to use their coupons. The impact of the intervention will be evaluated using a randomized controlled trial (RCT). The intervention will be implemented and data will be collected regularly over a period of approximately 12 months. Strict confidentiality procedures in line with Marie Stopes International's best practices will be put into place to ensure that information made public or otherwise distributed outside the principle investigators and other key personnel cannot be linked to any individual respondents. Results from the study will be published in a report, among other outputs, and the outcomes will be shared within MSI as well as with the wider SRH community.

Inclusion Criteria:

• Callers to the call centre who are over the age of 18, receive an e-coupon, and consent to participate in the research.

Exclusion Criteria:

• Callers who are below the age of 18, non-recipients of e-coupons, and those who receive e-coupons but do not consent to participate in the study.
