The problem
Intervention: Amaka Amasanyufu, a manualized family strengthening intervention delivered either by trained parent peers (Amaka-parents) or community healthcare workers (Amaka-community)
Who it was tested with: School-going children aged 8 and above residing in low-resource communities in Uganda who screened positive for ODD or other DBDs (n=636: Controls n=243, Amaka-parents n=194, Amaka-community n=199).
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.
"Three-level linear mixed-effects models were fitted to each outcome. Pairwise comparisons of postbaseline group means within each time point were performed using Sidak's adjustment for multiple comparisons." This describes a rigorous quasi-experimental longitudinal design with proper statistical controls for multiple comparisons, meeting the criteria for experimental evidence tier through the cluster randomized design with comparison groups across multiple time points.
Study limited to children who screened positive for ODD and DBDs, not a universal sample. Follow-up only extended to 16 weeks post-intervention initiation, so long-term sustainability of benefits is unknown. All participants were blinded but potential implementation fidelity variations between peer and healthcare worker delivery not reported.
