Behavioral Interventions for Pediatric Food Refusal Maintain Effectiveness Despite Integrity Degradation: A Preliminary Demonstration.
Your feeding protocol still wins even when you slip up, so keep going after small errors.
01Research in Context
What this study did
Ulloa et al. (2020) asked a practical question: does your feeding plan still work when you mess it up?
They used DRA plus escape extinction with three children who refused food. Then they purposely let adults make mistakes. They dropped the treatment steps down to only 20–40% correct.
The team watched if bites still went up and problem behavior stayed low even with sloppy delivery.
What they found
Two of the three kids kept eating well even when the adults followed the plan only two times out of five.
One child needed at least 40% integrity to keep the gains.
The package is tough: small errors will not ruin lunch.
How this fits with other research
Older papers already showed the parts work. Staddon et al. (2002) proved escape extinction is the engine; DRA is the polish. Najdowski et al. (2003) said the same: extinction drives consumption, reinforcement cuts yelling.
Scott et al. (2024) looked across 266 kids and found combining escape and non-escape extinction gives the biggest bite gains. Gabriella’s study adds: once you build that mix, it keeps running even when staff slip.
Engler et al. (2023) calm another fear. They saw extinction bursts in fewer than one-third of 60 cases. Together the papers say: use the full package, expect few bursts, and do not panic if your integrity dips to 40%.
Why it matters
You can train busy parents or new staff without demanding robot-perfect sessions. Aim for full integrity, but know the child will still eat if you hover around 40%. That safety margin makes home programs and classroom hand-offs far less stressful.

03Original abstract
Food refusal is commonly treated using behavioral treatment packages consisting of differential reinforcement of alternative behavior (DRA) and escape extinction. However, the effectiveness of such behavioral interventions is inextricably linked to the integrity with which the procedures are conducted. Although previous research has evaluated the effects of treatment integrity failures for behavioral interventions related to severe problem behavior and academic skill acquisition, the effects of these failures in the area of pediatric food refusal remain unknown. We conducted a parametric analysis to assess the effects of varying levels of errors on the treatment efficacy of contingent tangibles and attention, and escape extinction. Once stable responding was observed during an initial evaluation of treatment, participants were exposed to sessions of reduced-integrity treatment in descending order (i.e., 80%, 60%, 40%, and 20%) and subsequently exposed to full-integrity treatment (100% integrity). For one participant, integrity errors became detrimental to treatment when the level of integrity was decreased to 40%. For the other two participants, contingent tangibles and attention, and escape extinction remained effective despite being implemented with low integrity. Our preliminary demonstration suggests that behavioral interventions for pediatric food refusal remain effective despite considerable treatment integrity degradation.
