Strategies to Encourage Handwashing: Insights from Research
Written on
The Evolution of Hand Hygiene Awareness
There was a time when washing one’s hands was simply a routine task, rather than a celebrated act of public health. Personal cleanliness has always been crucial, but the urgency surrounding handwashing has surged, particularly due to recent global events. In a bygone era, the act of cleansing one's hands was a private affair, devoid of public demonstrations or widespread campaigns.
Back then, researchers embarked on studies to determine the most effective ways to encourage handwashing, and their findings offer valuable lessons.
Experiment 1 — Identifying the Audience
Conducted in a hospital, this study sought to assess how medical staff responded to varying health messages. Researchers positioned three distinct signs near hand-sanitizing stations and restrooms:
- A personal consequence message: “Hand hygiene protects you from getting sick.”
- A patient consequence message: “Hand hygiene protects patients from getting sick.”
- A neutral message (used as a control): “Gel in, wash out.”
Over two weeks, the volume of soap and hand-sanitizing gel used was recorded. For an additional two weeks, independent health professionals discreetly observed the hygiene practices of the staff.
Results from both measurement methods were striking. The sign that emphasized the impact on patients significantly increased hygiene practices among the staff. This highlights a common tendency for individuals to underestimate their own susceptibility to illness. When confronted with the potential effects their hygiene—or lack thereof—might have on others, compliance improved markedly.
A single word change made all the difference.
Experiment 2 — The Power of Tone
This experiment took place in a university setting and focused on how different tones of messaging influenced student handwashing behaviors. Four types of signs were displayed in restrooms:
- An assertive-praising message: “You’re doing great for your health! Keep it up—wash your hands with soap!”
- An assertive-scolding message: “You’re not doing enough for your health! You need to wash your hands with soap!”
- A non-assertive-praising message: “You’re doing a lot for your health. You could do even more. Please wash your hands with soap.”
- A non-assertive-scolding message: “You’re not doing enough for your health. You could do more. Please wash your hands with soap.”
Over five days, the soap usage was tracked and compared to a period without signage. The findings were clear: both the assertive-praising and non-assertive-scolding messages led to notably higher soap consumption.
The researchers concluded that while both praise and scolding are essential, the tone is as crucial as the content. For optimal results, deliver praise assertively or scold gently.
Current Public Health Messaging
Encouraging behavior change when individuals believe they are not being observed is challenging. The insights from these experiments shed light on key factors to consider when crafting public health messages (or any other type of communication):
- Carefully design your message; each word carries weight.
- Pay attention to your delivery, not just the content.
- Sometimes, appealing to a sense of responsibility toward others can be more motivating than focusing solely on self-interest.
Despite these insights, many still overlook these effective strategies. Current public health guidelines often emphasize personal protection rather than the potential impact on vulnerable individuals.
Although not everyone adhered to the recommendations in these studies, the methods that proved effective in a less urgent context may be even more pertinent today, as public health takes center stage.
