Data for: "The effect of community-based behaviour change interventions on observed handwashing and child faeces disposal in rural Malawi: a controlled before-and-after (CBA) trial"

The study was implemented in three sub-districts (also known as Traditional Authorities [TAs]). Two TAs received CLTS, which included an additional low-intensity government-led hygiene promotion campaign.

One TA received the standard CLTS intervention (CLTS group), and one received the same intervention but with additional sanitation and hygiene promotion delivered through local Care Groups (CLTS+CG group). The third TA served as the control group. Hygiene and child faeces disposal outcomes were measured by fieldworker direct observation at baseline (April 2023) and endline (March 2024).
