Experimental Design
This study evaluates a low-cost, low-intensity intervention -- facilitated "Mothers' Groups" -- designed to increase social network size and social capital among internally displaced mothers in Somalia. The study is structured as a randomized controlled trial conducted across major IDP-receiving areas in Hargeisa and Kismayo.
Eligible participants are mothers aged 18–50 who have been displaced within the previous three years due to conflict, drought, or related environmental and economic challenges, and who have at least one child between 10 months and 3 years of age. Recruitment occurs through two channels: outreach at health clinics providing antenatal or postnatal care, and direct household recruitment in IDP areas using a random-walk methodology with a short screening survey.
The treatment consists of 13 semi-monthly group sessions over approximately 6.5 months. Groups are targeted at 11 members and are geographically clustered to minimize travel. Sessions last roughly two hours and include informal group discussion, informational sessions on household management and childrearing, and mother-child interactive play. Mothers attend with their children, as part of the program's goal of modeling interactive, play-based parenting.
The study uses an oversubscription design. All recruited mothers complete a baseline survey before learning their assignment, which serves both to collect pre-treatment data and to function as a costly signal of interest, encouraging less motivated recruits to drop out before randomization. This protects internal validity by concentrating attrition in the pre-randomization phase. Post-randomization, participants who drop out are not replaced, with one exception: if a group falls below eight active members within the first four sessions, additional mothers are added to preserve the social dynamics essential to the intervention. These replacements are excluded from the analysis. Randomization is conducted at the individual level within geographic clusters, using block randomization on mother's age, child's age, and recency of displacement.
The study examines treatment effects along three causal pathways. First, a direct pathway through expanded social networks, hypothesized to improve information-sharing about livelihood opportunities and job referrals. Second, an indirect pathway through childcare access -- as network size and trust grow, mothers gain access to reliable informal childcare, enabling labor force participation. Third, an indirect pathway through mental health -- social support is expected to reduce stress and depression, improving participants' capacity to pursue employment. The study measures both intermediate outcomes (network size and strength, childcare access, mental health) and final outcomes (employment, self-employment, and hours worked).
Data will be collected through baseline and endline surveys supplemented by higher-frequency surveys conducted during group sessions, capturing granular labor market data such as weekly hours worked. The pilot sample includes 176 treatment and 176 control participants. The primary estimands are the intent-to-treat effect and the complier average causal effect, estimated using difference-in-differences models. A detailed pre-analysis plan will be developed following the baseline survey.
