Abstract
The objective of this evaluation is to use a randomized design to evaluate the effect of sending a series of mobile SMS follow-ups to beneficiaries who have received referrals for family planning services from a family planning promoter in urban and peri-urban Mozambique (Nampula and Sofala provinces). Currently, only about 50% of beneficiaries who receive referrals ever redeem them by visiting a family planning clinic. This evaluation seeks to understand whether behaviorally informed SMS messages can be a cost-effective means of increasing the referral redemption rate among beneficiaries. The project is implemented by the Office of Evaluation Sciences, supporting the USAID-funded Integrated Family Planning Program (IFPP) in Mozambique led by Pathfinder International; the component of the IFPP that will be evaluated in this project is led by Population Services International (PSI).

Experimental Details
Interventions
Intervention(s)
The proposed intervention is a series of mobile message follow-ups for beneficiaries who have received referrals to encourage them to redeem their referral. The reminders will include basic information about when the referral was received, a reminder to redeem it, and encouragement to contact the promoter. Six substantive messages will be sent within the first month following the promoter's visit, on the following schedule: one day post-visit (or as soon as the respondent's consent can be verified), three days post-visit, and at one week, two weeks, three weeks, and four weeks. These messages will be supplemented by an additional introductory message and a thank-you message at the end of the month.

Experimental Design
Experimental Design
Beneficiaries will be randomized at the individual level into the following conditions.

Control (status quo) — Promoters will follow up as normal, according to the schedule laid out above based on each woman’s segment type.

Treatment — Beneficiaries will receive a series of electronic follow-ups reminding them to redeem their referrals or follow up with their promoter, as described above.

Enrollment will be conducted on an ongoing basis as promoters visit new beneficiaries; eligible beneficiaries who provide consent will be enrolled into the sample, and randomization will be conducted twice weekly.

Randomization Method
Randomization will be conducted bi-weekly in Stata.

Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
The projected sample size is between 3700 and 5100; the numbers will vary based on the promoters' ability to rapidly verify consent for beneficiaries in the field. These projections reflect estimates constructed post-piloting.
Sample size: planned number of observations
As above
Sample size (or number of clusters) by treatment arms
The sample size per treatment arm is between 1850 and 2550.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
The minimum detectable effect ranges between 3.9 and 4.6 percentage points, relative to a base redemption rate of vouchers of 50%.
