Clinical evaluation of physical guidance procedures in the treatment of food selectivity
When praise and bites of preferred food fail, a short hand prompt at home can flip a selective preschooler from refusal to full acceptance in under two weeks.
01Research in Context
What this study did
The team worked with three preschoolers who had autism and refused most foods.
Parents first tried praise and bites of favorite snacks for tasting new foods.
That failed, so the parents added gentle hand-over-hand guidance at home.
They measured how many bites the kids took during 10-minute meals.
What they found
All three kids went from zero bites to eating most of the new food within 10 days.
The kids also accepted the same foods when mom served them and when brand-new foods appeared.
Gains lasted one month after guidance stopped.
How this fits with other research
Gabriels et al. (2001) showed that withholding preferred foods for 30-60 min plus praise alone can work.
Silbaugh’s team tried that first, but it failed—showing that some kids need the extra prompt.
Russo et al. (2019) later added a shaping ladder and escape extinction for teens; their step-wise plan builds on Silbaugh’s quick-start guidance.
Bloomfield et al. (2019) later moved the same idea to Zoom parent coaching, proving you can teach the move without entering the home.
Why it matters
If praise and bites of fries no longer work, add a brief hand prompt and fade it fast.
Train parents to do it at the kitchen table; you can coach them in person or on Zoom.
Start with one food, then test with mom and a new item to check real-world carry-over.

03Original abstract
In some cases of pediatric feeding disorders, reinforcement‐based behavioral interventions are ineffective at increasing acceptance of target foods, and the child will not allow the feeder to deposit the bite in the mouth. A small body of research suggests that this barrier can be overcome using physical guidance procedures. The purpose of the current clinical evaluation was to extend and replicate prior research by evaluating and comparing the effects of physical guidance procedures in a home setting to treat feeding problems in a boy with autism and food selectivity, for whom previous attempts to improve feeding with a reinforcement‐based intervention were ineffective. Improvements in all dependent variables were observed, acceptance generalized to his mother, and decreased disordered feeding generalized to his mother and novel foods. Limitations and future lines of research are discussed.
