Hand Hygiene-Related Screen Savers May Boost Compliance:
5 Study Findings

any hospitals post hand hygiene reminders out-
side patient rooms or above sinks, but a study
published in the American Journal of Infection
Control suggests hospitals can boost compliance by dis-
playing hand hygiene messages on screen savers as well.
Based on previous literature, researchers developed
scientific propositions for the design of screen savers, ex-
ploring two strategies to subconsciously influence hand
hygiene behavior: designs aimed at getting attention and
designs aimed at exerting peer pressure. The researchers
tested reactions to the screen savers using eye-tracking
and a questionnaire, comparing reactions to the newly
designed screen savers with a control screen saver.
Here are five takeaways from the study.
1. All total, 25 scientific propositions for gaining attention
concerned the format and color of the screen saver itself
as well as the color, position and style of visual and text
elements.
2. Seven propositions for peer pressure concerned the
influence of peers, role models and feelings of being
watched.
3. Ultimately, eye-tracking measurements found text on
the four screen savers based on propositions gained
more, earlier and longer attention than the control screen
savers.
4. The visual elements gained earlier and longer atten-
tion than the control screen savers.
5. The questionnaires revealed feelings of peer pressure
were evoked by three screen savers; of these, only one
was not based on the scientific propositions.
Given the results of the study, the authors concluded that
screen savers designed using scientific propositions for
visual attention and peer pressure "have the potential to
alter hand hygiene behavior." n
