Background: Infectious diseases are common among schoolchildren as a result of their poor hand hygiene, especially in those who have developmental disabilities. Methods: A quasi-experimental study using a pre- to post-test design with a control group was used to test the feasibility and sustainability of simplified 5-step handwashing techniques to measure the hand hygiene outcome for students with mild intellectual disability. Sickness-related school absenteeism was compared. Results: The intervention group experienced a significant increase in the rating of their handwashing quality in both hands from pre- to post-test: left dorsum (+1.05, P <.001); right dorsum (+1.00, P <.001); left palm (+0.98, P <.001); and right palm (+1.09, P <.001). The pre- to post-test difference in the intervention group (+1.03, P <.001) was significantly greater than the difference in the control group (+0.34, P =.001). There were no differences between the post-test and the sustainability assessment in the intervention group. The intervention school experienced a significantly lower absenteeism rate (0.0167) than the control group in the same year (0.028, P =.04).Students in this study showed better performance in simplified handwashing techniques and experienced lower absenteeism than those using usual practice in special education school settings. Conclusion: The simplified 5-step hand hygiene technique has been proven effective in reducing the spread of infectious diseases.
