An application of the trial‐based functional analysis to assess problem behavior evoked by ritual interruption

Four autistic kids who hit, screamed, or flopped when their rituals were blocked came to an outpatient clinic.

The team ran a 5-minute trial-based FA each session. They broke the child’s ritual for 30 s, then let them finish.

After the FA showed escape was the pay-off, staff taught the kids to hand over a card that said “Let me finish.” They used a multiple schedule: green card meant the ritual would stay open, red card meant it would end soon.

All four kids stopped problem behavior once the FCT card worked. Three kids kept the gains when new rituals were introduced.

Sessions took only 15 min start-to-finish, so the whole assessment plus treatment fit into one clinic visit.

Scotchie et al. (2023) used the same quick-trial FA idea, but for kids who spit out food. Both studies show you can spot the pay-off in minutes if you test the right conditions.

Sullivan et al. (2020) warns that when you first withhold escape, other problem forms can pop up. Weyman’s team saw this too, but the multiple schedule kept the new FCR strong and blocked resurgence.

McConnell et al. (2020) also paired escape extinction with graduated exposure, but at the dentist’s office. Their success with adults shows the ritual-FCT package could travel to medical settings next.

If a child melts down when you tidy his toys or turn off the tablet, you can test the function in under ten minutes. Teach one simple card, then use green/red cues to tell the child when the ritual can finish. You get zero problem behavior without long standard FAs or bulky reinforcement menus.
