The problem
Intervention: Family-based interventions for parental substance use disorders
Who it was tested with: 300 participants in Yenagoa, Nigeria including parents with substance use disorders, their spouses, and children; compared against individual-only treatment group (n=98 for behavioral outcomes).
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.
"Families receiving family-based interventions demonstrated significantly healthier functioning (M = 82.4) than those in individual only treatment (M = 58.6) [t(98) = 9.45, p < .001]." The study used a comparison group design measuring outcomes across family-based and individual-only treatment approaches, with statistical tests indicating significant differences favoring the family-based intervention.
Study does not clearly specify random assignment procedures, follow-up duration, or generalizability beyond Yenagoa. No details provided on treatment fidelity, dropout rates, or potential confounding variables.
