Nudging Handwashing among Primary School Students in the Philippines: Evidence from a Cluster Randomized Trial.

Handwashing is key to preventing the transmission of various infectious diseases of which school-aged children are particularly susceptible. Traditional, information-messaging campaigns may increase handwashing awareness but have had limited success in promoting behavior change. Behavioral economics "nudges," which explicitly target the knowledge-behavior gap, is a promising alternative.

Can Social Motivators Improve Handwashing Behavior among Children? Evidence from a Cluster Randomized Trial of a School Hygiene Intervention in the Philippines.

This study reports the impact of the HiFive program, a 6-week handwashing campaign that targets social and emotional motivators to improve student handwashing in primary schools in the Philippines. We designed a clustered randomized trial to evaluate the impact of HiFive on student handwashing behavior, motivation, and access. Of the sample of 196 primary schools located in two districts, half were randomly assigned to receive the program in the 2017-2018 school year.
