The Effect of Behaviour Change Interventions on Use of Public Handwashing Stations in Bangladesh
Bangladesh855 participantsStarted 2021-01-03
Plain-language summary
As part of the COVID-19 response, BRAC has built 1000 public handwashing stations in several hundred villages in 20 sub-districts of Bangladesh. The investigators investigate the effects of two sets of behavioural interventions on use of the handwashing stations, compared to no additional interventions. The first set comprises passive nudges installed on and around the handwashing station, aimed at attracting people to the station. The second set comprises actively delivered higher-intensity interventions, including free soap offered as an incentive for using the handwashing station and a community board used to display social proof. This set of interventions aims to increase motivation to use the station.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Note: the sample consists of villages that have received at least one public handwashing station from BRAC, rather than human participants, though the investigators are measuring the use of the stations by human participants.
The initial sample of villages has been chosen from a set of 1,899 villages identified by BRAC as being eligible for this project based on criteria related to COVID-19 cases, existing BRAC programs and village characteristics. The villages are spread across 3 of Bangladesh's 8 divisions, 8 of its 64 districts, and 20 of its 492 subdistricts ('upazilas'). While most of the 'villages' are located in rural parts of Bangladesh, roughly 15 percent are better characterised as wards or towns within urban and peri-urban municipalities.
Inclusion Criteria:
Villages identified by BRAC as being eligible for this based on:
* COVID-19 cases
* Existing BRAC programs
* village characteristics
* viable location for a handwashing station (space/water source)
* local community members willing to 'sponsor' and maintain handwashing station
Exclusion Criteria:
* Lack of viable location for a handwashing station.
* Villages that received handwashing stations as part of the pilot phase
* Villages randomly selected in a related impact evaluation measuring the impact of the stations themselves
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
