GoKawiilHonduras trial shows health-worker intervention reshapes village social networks
Researchers ran a randomized controlled trial across 176 Honduran villages in Copán Department, enrolling 24,702 people who agreed to monthly health-worker visits, randomization and repeated surveys over 22 months. Within a subset of 110 villages assigned to random-targeting arms, dosage of the intervention varied from 0% (control) to 100% of residents, allowing researchers to study how varying levels of treatment altered village-level social network structure.
GoKawiil's interpretation of the reporting above, not reported fact.
The findings suggest that targeted public-health interventions can do more than change individual behavior—they may reshape the underlying social ties through which information and norms spread, according to the researchers' framing of their study design. This could inform how future health campaigns are designed to maximize spillover effects by strategically choosing who receives direct intervention. The scale and rigor of the trial, with tens of thousands of participants, lends weight to conclusions about network-level effects rather than just individual outcomes.
- Trial enrolled 24,702 people across 176 Honduran villages for a 22-month study.
- 110 villages were randomized to different intervention dosages, from 0% to 100% of residents treated.
- Study examines how such interventions can alter village social network structures, not just individual behavior.
