An evaluation of food type and texture in the treatment of a feeding problem.

Patel et al. (2002) · Journal of applied behavior analysis 2002
★ The Verdict

Lower food texture first when a toddler spits food out — it worked fast for one 3-year-old.

✓ Read this if BCBAs treating toddlers who expel food during meals.
✗ Skip if Clinicians whose clients already accept all textures.

01Research in Context

01

What this study did

Staddon et al. (2002) worked with one 3-year-old who kept spitting food out.

They simply made the food softer and smoother.

Then they counted how often the child still pushed the food out of his mouth.

02

What they found

When the food texture was lowered, the child spat it out far less often.

The softer version of the same food stayed in his mouth and was swallowed.

03

How this fits with other research

Scotchie et al. (2023) later tested many food changes at once.

They found that lowering texture was often the key, backing up this 2002 result.

Coe et al. (1997) had cut expulsions too, but they used re-presentation instead of texture change.

Both methods work; texture is just faster to try first.

04

Why it matters

You can run this change in seconds.

Just puree, mash, or add sauce to the target food and watch the next bite.

If expulsions drop, keep that texture and slowly thicken it across meals.

No extra staff or gear needed.

03Original abstract

An evaluation of food type and texture indicated that both variables affected the expulsions of a 3-year-old with feeding problems. The results of the evaluation were used to prescribe a treatment (reducing the texture of one food type) that reduced expulsion.
