“Our interventions were all temporary, but we continued to track handwashing behavior — so this gives us a measure of persistence, which is basically whether or not handwashing is a habit-forming behavior or not.”
To celebrate Global Handwashing Day 2017, Global Waters Radio recently spoke with USAID’s Nga Nguyen and Harvard University’s Dr. Reshmaan Hussam about incentivizing handwashing behavior change, following up on September 2017 webinar on the subject co-hosted by USAID and the Global Handwashing Partnership.
Nga Nguyen is the Senior Water, Sanitation and Hygiene and Social Behavior Change Advisor at USAID’s Office of Maternal and Child Heath and Nutrition. She has more than 15 years of field experience in social and behavior change focusing on a variety of behaviors. In this podcast, Reshmaan Hussam, an economist and assistant professor at Harvard Business School whose research explores the intersection of development, behavioral, and health economics, speaks with Nga about the role of learning and habit formation in achieving sustainable changes in handwashing habits, and shares her insights about recent handwashing field studies her team has conducted in India’s rural West Bengal state.
“Across the board for these preventative health behaviors, the way people measure outcomes is usually either self-report — so you ask people ‘Do you wash your hands with soap?’ — or you have surveyors going in and checking whether people wash their hands with soap. And both of these sorts of outcomes are very noisy, they are imprecise, and they are not going to give us the statistical power to really think about habit-formation dynamics.”
