The study will collect and analyze quantitative data regarding handwashing behaviors among school-aged children to determine the impact of nudges compared to handwashing and hygiene education programs. Based on the success of the preliminary pilot, we hypothesize nudges leading to higher rates of handwashing than traditional handwashing and hygiene education programs.
This study will utilize a cluster-randomized trial design to collect quantitative data and analyze the handwashing behaviors of school-aged children. The primary purpose of this protocol is to assess nudges as a viable method of promoting handwashing among school-aged children. The specific objectives of this quantitative exploration are to: 1. Determine if nudges can prompt significant behavior change and result in higher rates of handwashing among school-aged children in Bangladesh 2. Determine if behavior change resulting from nudging is sustainable over time

A handwashing station will be a dedicated location for handwashing in each selected school and will include: 1. A raised concrete platform (built to child height) 2. A plastic container with a lid and spigot 3. Soap The early handwashing stations will be constructed in weeks 1 and 2 of the study, after the baseline observations (Phase I) are complete.

Change in the probability of handwashing with soap after a toileting event among students receiving nudge intervention compared to that of students in hygiene education group
Students will be randomized into Nudge intervention or Hygiene Education intervention at the completion of data collection in week 6, and the change in probability, or prevalence ratio, will be assessed over time, with measures at weeks 4-5, weeks 6-7, week 12, weeks 18-19 and weeks 24-25, comparing the probability of handwashing of nudge students post-toileting event to that of hygiene education students post-toileting event, measured using camera observations of the handwashing station outside of the latrine area.
Time frame: Weeks 6-7, Week 12, Weeks 18-19, Weeks 24-25
Change in the probability of handwashing with soap after a toileting event among students who received the early handwashing station intervention compared to students who received the late handwashing station intervention
Students will be randomized into early handwashing station intervention (built in weeks 1-2) or late handwashing station intervention (built in weeks 3 and 4), and the change in probability, or prevalence ratio, will be assessed at week 2-3 and week 4-5, comparing the probability of handwashing of the early handwashing station students post-toileting event to that of the late handwashing station students post-toileting event, measured using camera observations of the handwashing station outside of the latrine area.
Time frame: Weeks 2-3, Weeks 4-5
Change in the probability of handwashing with soap after a toileting event within the nudge intervention group, comparing students in the early handwashing station intervention to students in the late handwashing station intervention
In order to assess if the timing of the handwashing station building influences handwashing, the change in probability, or prevalence ratio, will be assessed over time, with observations at weeks 4-5, weeks 6-7, week 12, weeks 18-19 and weeks 24-25 within the Nudge group, comparing the probability of handwashing among students who received the early handwashing station (built in weeks 1 and 2) to the probability of handwashing among those students who received the late handwashing stations (built in weeks 3 and 4), measured using camera observations of the handwashing station outside of the latrine area.

A nudge will be built in each randomly selected school and will consist of: 1. Connecting latrines to the handwashing station via paved pathways that are painted bright colors 2. Painting footprints on infrastructure guiding students to the handwashing stations and handprints on stations The nudges will be constructed at the end of week 3 and 4, after Phase II data collection is complete within each randomly assigned nudge school.
Hand hygiene education-based program: the hygiene promotion element will include a one month program of handwashing education involving weekly facilitator led sessions. Each session will be about 30-45 minutes long, and will cover the following topics: * Importance of handwashing * Method of handwashing * Critical times of handwashing * Finding solutions for handwashing in school and at home The sessions will involve use of flipcharts, and other IEC materials (e.g. videos) and participative learning methods. The Hand hygiene education-based program will begin at the beginning of weeks 4 and 5, after Phase II data collection is complete in each randomly assigned education school.
