Further examination of the treatment of multiply controlled inappropriate mealtime behavior

Kirkwood et al. (2021) · Journal of Applied Behavior Analysis 2021
★ The Verdict

When food refusal is fueled by both escape and attention, you must block both pay-offs and reinforce bites; single-function plans fail.

✓ Read this if BCBAs treating multiply controlled food refusal in clinic or home feeding sessions.
✗ Skip if Clinicians whose clients only need simple food selectivity or texture expansion.

01Research in Context

01

What this study did

Four kids with feeding disorders sat at a table. Each child refused food for two reasons. Some wanted to escape the demand “take a bite.” Others wanted Mom’s attention when they spat.

The team first watched each child during meals. They saw which refusal got escape and which got attention. Then they wrote one plan that blocked both pay-offs. Kids earned a toy bite-by-bite. At the same time, spitting no longer removed the spoon and crying no longer brought Mom close.

02

What they found

Three of the four children soon took 80-100 % of bites. Spitting, head-turning, and crying dropped to almost zero. The fourth child improved only after the team added stricter escape blocking.

When the plan missed one function—say, only blocking escape but still giving attention—problem behavior bounced back. Matching every function mattered.

03

How this fits with other research

Chen et al. (2022) asked a different question: should we give the toy right after each bite or save it up? They still found big gains, showing the toy itself works. Kirkwood shows the toy must be paired with blocking every function, not just one.

ALee et al. (2022) got kids with autism to eat using praise alone. That looks like a contradiction—why add extinction here? Their kids only had food selectivity, not escape-plus-attention refusal. Mild pickiness may yield to praise; multiply controlled refusal needs the heavier package.

Van Arsdale et al. (2024) reviewed 15 recent feeding studies. Many named noncontingent reinforcement, but few defined it the same way. Kirkwood gives a clear recipe: deliver the reinforcer for eating while you withhold it for refusal, and do this for every identified function.

04

Why it matters

If you run a feeding protocol and see quick gains that later slip, check your functional assessment. One missed function can keep the whole top spinning. Write separate extinction rules for escape and for attention, then reinforce each bite on the spot. Start Monday by re-probing refusal—one trial with escape blocked, one with attention blocked—and adjust your plan before the spoon hits the tray.

03Original abstract

We systematically replicated Bachmeyer et al. (2009) by examining extinction procedures matched to each function, individually and in combination, to treat the food or liquid refusal of 4 children diagnosed with a feeding disorder whose inappropriate mealtime behavior was maintained by multiple functions (i.e., escape and attention). Previous research suggests that adding differential reinforcement to extinction procedures may result in better treatment outcomes. Therefore, we added differential reinforcement to extinction procedures matched to each function. Differential reinforcement and extinction matched only to escape or attention resulted in low rates of inappropriate mealtime behavior and high, stable levels of acceptance for only 1 child. Consistent with Bachmeyer et al., inappropriate mealtime behavior decreased, and acceptance increased for the remaining 3 children only after we matched differential reinforcement and extinction procedures to both escape and attention.
