The problem
Intervention: Sugira Muryango Program (SM), a home-visiting intervention designed to improve caregiving practices and family dynamics
Who it was tested with: 247 younger siblings (aged 0.3-3 years) of children enrolled in the Sugira Muryango Program in Rwanda, including those exposed to domestic violence.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"This study utilized a spillover effect cohort design, focusing on 247 younger siblings of children enrolled in the Sugira Muryango Program (SM) to assess potential spillover effects of the intervention. The temperament of these siblings was measured using the Infant Behavior Questionnaire-Revised Short Form...Multiple linear regression analysis was performed using SPSS version 29, with the treatment group (SM vs. UC) as the main predictor and temperament as the dependent variable." The study used a randomized controlled design with comparison groups to test whether family-level improvements would indirectly benefit younger siblings not directly exposed to the intervention.
The study examined spillover effects rather than direct intervention effects on primary recipients. External factors including the COVID-19 pandemic may have influenced intervention effectiveness. The study design assumes benefits would manifest indirectly through improved family dynamics.
