Handwashing Nudges in Zamboanga del Norte: Final Report

In 2019-2020, IDinsight evaluated a handwashing “nudges” intervention in Zamboanga del Norte elementary schools, with the support of UNICEF, USAID (through a WASHPaLS behavior change innovations grant), and in collaboration with the Philippines Department of Education. Nudges are environmental changes that “[alter] people’s behavior in a predictable way.” The tested intervention consisted of the following nudges: painted footpath with spray-painted footprints from toilet stall to handwashing station, calendar of handwashing posters, “watching eye” sticker above the handwashing station, and arrow sticker pointing to a soap dish. This report details the results of the evaluation, which are intended to inform scale-up recommendations about the pilot intervention.
