Task Clarification and Feedback Improves Room Tidiness and Safety in a Training Center

Ng and colleagues tested a two-step package at a Hong Kong training center. First they gave staff a one-page sheet that spelled out exactly what a tidy room looks like. Then they posted simple feedback charts showing each room’s daily tidiness score.

They used a multiple-baseline design across participants and rooms. That means they staggered when the package started so they could be sure any change came from the intervention, not something else.

Rooms got noticeably cleaner and safer once the sheet and charts were in place. The gains showed up right after the package began and stayed while feedback continued.

Chinnappan et al. (2020) ran a near-copy of the idea in India. They swapped the written sheet for posted rules and targeted adolescent problem behavior instead of clutter. Problem behavior still dropped to under 10 % of intervals, showing the same clarification-plus-feedback engine works even when you change the form.

Striefel et al. (1974) did the bare-bones version decades earlier. They used only feedback—no written sheet—and still cut disruptive acts. Ng’s study adds the clarification piece and shows the combo is stronger than feedback alone.

Zhu et al. (2020) took the concept online. They gave BCBA trainees remote feedback through Zoom and lifted caregiver-coaching fidelity without anyone in the room. Together these papers draw a clear line: whether you serve teens, staff, or trainees, in person or on screen, a quick clarification plus feedback keeps behavior on track.

You can clean up a space—or any staff skill—without extra rewards or long trainings. Write the top three criteria, post a daily score, and watch the room stay safe. It takes ten minutes to set up and saves hours of nagging later.
