To evaluate the effects of a simplified hand washing improvement program in schoolchildren with mild intellectual disability: a pilot study.
A quick tablet video, five clear steps, and star rewards sharply raise hand-washing quality in elementary students with mild ID.
01Research in Context
What this study did
Smith et al. (2014) tested a 4-week hand-washing program in a special-ed classroom. The kids had mild intellectual disability and were 5-11 years old.
The team used five steps shown on a tablet: turn on water, soap, scrub, rinse, dry. Kids earned a star on a chart each time they hit every step. No stars were given for messy washes.
What they found
After four weeks the class that got the program washed hands much better than the class that did not. Quality gains were large and easy to see.
The stars kept the kids engaged. Teachers only needed a tablet, paper chart, and stickers.
How this fits with other research
Eussen et al. (2016) reviewed thirteen health programs for people with ID. They found wide swings in success and no single best package. T et al. adds a clear, short model that works.
Mammarella et al. (2022) later used the same BST-plus-reward idea to help adults with IDD sit through a real dental exam without sedation. Their results extend T et al. from schoolkids to grown-ups and from hand washing to dental care.
Vassos et al. (2023) ran a parent-led social-story program that boosted toothbrushing in preschoolers with autism. Both studies pair a simple visual aid with praise or tokens and get strong self-care gains, showing the idea crosses diagnoses and ages.
Richmond (1983) first showed that shaping plus praise could potty-train preschoolers with delays in about four weeks. T et al. mirrors that timeline but swaps in video clips and stars for hygiene instead of toileting.
Why it matters
You can copy this package Monday morning. Load a short 5-step video on a tablet, post a star chart by the sink, and reward perfect washes on the spot. Four weeks is enough to see clear gains in students with mild ID or autism, and you do not need extra staff or gear.

03Original abstract
A quasi-experimental study using a pretest-posttest design with a control group was used to evaluate the effects of a simplified 5-step multimedia visualization hand hygiene improvement program by schoolchildren with mild intellectual disability (MID). A total of twenty schoolchildren aged 6-12 years old with MID (12 males) were recruited and they were assigned into intervention (n=10) and control (n=10) groups. To evaluate the quality of their hand washing, Glow gel, which contains plastic simulated germs that are visible under an ultra-violet lamp, was applied to participants' hands to assess the quality of hand washing by comparing the amount of visible Glow gel before and after hand washing using a 4-point scale. Four raters used this 4-point scale to assess the quality of hand washing through digital photo images of the participants' hands. A total of eight digital photos per participant were taken. A fifteen-minute hand washing training session was conducted every school day for 4 weeks for the intervention group. Those in the control group received no training. A multimedia visual package on steps of hand washing was presented together with a reward system, whereby a number of stars were earned each week depending on the quality of hand washing. Results showed encouraging findings, as the schoolchildren in the intervention group showed significant improvement in hand washing (p<0.001) and the improvement was stronger than that of the control group (p=0.02). To conclude, a systematic instruction emphasizing multimedia visualization in a hand washing improvement program can be successfully implemented in a special school, and the effect of integrating multimedia visuals in the hand hygiene program could improve hand hygiene among schoolchildren with MID.
