On the efficacy and efficiency of treating pediatric feeding disorder
Pair escape extinction with any non-escape tactic to speed up feeding gains for kids who gag, spit, or refuse food.
01Research in Context
What this study did
Scott et al. (2024) looked at 266 kids with feeding disorders. They pulled data from every published study that used escape extinction. They compared escape-only plans to plans that added extra steps like high-probability sequences, praise, or finger prompts.
The team asked two questions. Which plan cuts problem behavior fastest? Which plan helpss food acceptance most? They used meta-analysis to crunch the numbers across all cases.
What they found
Plans that mixed escape extinction with other tactics won. Kids showed bigger drops in screaming, spitting, and head turns. They also took more bites of new foods.
Escape-only still worked, but gains came slower. Adding non-escape pieces shaved days off treatment without extra effort.
How this fits with other research
This finding builds on Chawner et al. (2019). Their 2019 review of 36 studies already hinted that multi-part plans help. Scott’s 2024 data now proves it with hard numbers.
Older single-case papers like Giallo et al. (2006) and Carr et al. (2003) showed the same pattern. They tested high-probability sequences plus escape extinction in just two or three kids. The new meta-analysis confirms those small studies were right.
Richman et al. (2001) and Swaim et al. (2001) taught parents to add praise and fixed meal lengths at home. Scott’s work shows these parent-friendly add-ons still boost success when rolled out clinic-wide.
Why it matters
You no longer need to choose between fast behavior cuts and food acceptance. Add one non-escape step to your extinction plan tomorrow. Try a three-step high-probability sequence before the bite or add brief praise after every swallow. The data say you will reach mastery sooner.

03Original abstract
Inappropriate mealtime behavior (IMB) is a type of feeding challenge within the broader class of food refusal. The purpose of this study was to critically analyze the efficacy of interventions for the treatment of IMB through a meta-analysis of research using single-case experimental designs. We examined the extent to which different interventions resulted in decreases in IMB while also producing increases in food acceptance. This meta-analysis was also used to examine the efficiency of different interventions in achieving clinical significance. We identified 38 studies involving 266 cases in which IMB was treated with a behavioral intervention. The results indicated interventions that combined escape extinction and non-escape extinction had greater effect sizes for both reducing IMB and increasing food acceptance than either escape extinction alone or non-escape extinction alone. However, interventions that included escape extinction were slightly less efficient at decreasing IMB than were interventions that did not include escape extinction. We discuss the implications of these findings and provide recommendations for future research.
