Evaluating the Impact of Behavioral Nudges on Student Hand-washing in Elementary Schools in the Philippines

"Behavioral nudges include the following:~1. Colorful pathway overlaid with footprints leading from the toilet to the handwashing station~2. Rotating posters in toilet areas with messages targeting behavioral motivators for handwashing (disgust, social affiliation)~3. Sticker of a pair of eyes placed above the handwashing station~4. Soap dish with an arrow beside it on the sink or counter to remind children to wash their hands with soap"

"The Philippines' Department of Education National WASH in Schools (WinS) policy promotes correct hygiene and sanitation practices among school children and a clean environment in and around schools and includes initiatives related to infrastructure, knowledge, and behavior change, but does not include other programs with an explicit focus on handwashing promotion."
