Diarrhea is a bigger global killer than HIV and malaria combined. It accounts for more than 800,000 deaths each year among children 0-5 years. And how tragic this is when the simple intervention of hand washing can prevent some of these deaths. Results of a trial, published in the March edition of The Lancet Global Health, indicate that teaching families in under-resourced areas of the world about hand washing is not only possible but also scalable, sustainable and successful—if it’s done the right way.

Hand washing is a simple intervention, but the prevalence of the behavior is as low as 1 to 2 percent in some under-resourced global settings. A London School of Hygiene and Tropical Medicine group, led by Adam Biran, PhD, decided to try to improve these statistics by devising an effective intervention.

However, the route to simple solutions is often complex. The researchers used very sophisticated methodology to identify the levers of behavioral change. They realized that health messages about hand washing have not worked. The idea that what I do today may prevent diarrhea down the road just did not have enough oomph to motivate people to adopt a new routine.

The researchers hypothesized that emotional drivers (including nurture, status, disgust and belonging) would be strong pushes to get families to wash their hands. And they were right. Full story »
