Effects of setting events on the problem behavior of students with severe disabilities.

Two small groups of students with severe disabilities took part. Each kid had problem behavior that happened most school days.

The team ran an ABAB reversal design. They first watched normal mornings. Then they removed common setting events like loud entry routines or missing breakfast. Next they brought the events back. Finally they removed them again.

Problem behavior dropped every time the morning setting events were gone. When the events returned, the behaviors came back. The pattern repeated in both groups.

Galbicka et al. (1981) first named setting events twelve years earlier. This study gives real classroom proof for their idea.

Chandler et al. (1992) tried the same logic with preschoolers. They added setting events to boost social play. Kennedy et al. (1993) flips the coin by removing events to cut problem behavior. Same concept, opposite aim.

McGill et al. (2003) later asked staff to list idiosyncratic setting events. Their survey method extends this work by showing each child has unique triggers, not just the common morning ones.

Before you write a behavior plan, run a quick morning check. Did the student skip breakfast? Was the bus late? Did they miss their preferred aide? Remove or fix these setting events first. You may see problem behavior fall all day without extra reinforcement or punishment programs. It takes minutes and costs nothing.
