Sequential assessment of staff administration of contingency management procedures on a child psychiatric unit.

The team watched nurses and aides on a child psychiatric unit for 30 seconds at a time. They used a simple code sheet called the CSSPI to mark each time staff praised, redirected, or ignored a child.

They kept score for every worker across different shifts. Then they looked at how past training and daily stress matched the scores.

Staff gave very different amounts of attention from shift to shift. Some workers praised kids often; others rarely did. Stress and years on the job helped explain who was steady and who was not.

The data showed clear gaps in how the same rules were carried out. Supervisors could see exactly which staff needed help and when.

Kunz et al. (1982) ran a similar check in an infant room. They proved that a staff-made chart plus quick feedback fixes the very gaps J et al. spotted. The two studies line up: measure first, then coach.

Northrup et al. (2022) later used the same 30-second rule to track autistic in-patients’ meltdowns. Their tool was newer, but the rhythm—watch, code, act—copies the 1989 plan. The setting and targets differ, yet the method holds.

Toby et al. (2024) built the POP-C calculator to help new BCBAs choose therapy hours. Like the CSSPI, it gives rookies a ready score sheet so they do not have to guess. The idea of simple decision aids for frontline staff runs from 1989 to today.

You can borrow the 30-second CSSPI scan during your next supervisory visit. Pick one routine—transitions, meals, or recess—and tally staff praise, prompts, and ignores for ten minutes. Share the quick counts with the staff right after the session and set a small goal for the next shift. This fast check turns vague “be more consistent” into clear numbers staff can beat.
