Impact evaluation of training natural leaders during a Community-Led Total Sanitation intervention: a cluster-randomized field trial in Ghana
Sanitation and hygiene interventions often recruit and train local actors to influence the behaviors of others. However, while studies have reported beneficial behavioral outcomes, no study has attributed outcomes to training. We used a cluster-randomized field trial to evaluate training natural leaders (NLs) of communities during Community Led Total Sanitation (CLTS) in Ghana. NL training led to increased time spent on CLTS by community members, increased latrine construction, and a 19.9 percentage point reduction in open defecation (p < 0.001). For greatest impact, NL training should be used in small, socially cohesive, remote villages with low exposure to prior water and sanitation projects. Use of NL training with CLTS helps countries achieve Sustainable Development Goal 6 by eliminating open defecation, expanding capacity-building in developing countries, and strengthening community participation.
