Robert Dreibelbis is a Lecturer at the London School of Hygiene & Tropical Medicine and an Assistant Professor in the University of Oklahoma’s Department of Anthropology and Department of Civil Engineering and Environmental Sciences. Dreibelbis shares with Global Waters Radio his experiences with a handwashing behavior change pilot project in Bangladesh that delivered promising results obtained using subconscious environmental cues called “nudging.” Without the use of additional handwashing education interventions, the nudge-based intervention implemented by Dreibelbis and his team increased handwashing among school children by 72 percent during the trial period.
“There’s a very pragmatic approach to this, we want to know what mechanisms are feeding into these large improvements in handwashing. We are trying to understand if we are able to change certain behaviors, or start new habits or social norms around hand washing — and the various ways this intervention could influence handwashing behavior.”
Dreibelbis also discusses the project’s implications for future handwashing behavior change research, particularly in the healthcare industry. A nudge-based approach to handwashing hygiene improvement in clinics and hospitals incorporating simple changes to infrastructure, availability or placement of handwashing facilities could drive significant hygiene improvements among healthcare workers, he suggests.
