Managing Feeding Problems in Persons with Autism using Behavioral Interventions.

ALee et al. (2022) worked with 24 non-verbal autistic kids in a residential school.

All kids refused most foods and ate fewer than five things.

Staff gave a tiny bite of a new food and praised the child if they swallowed.

No demands, no toys removed—just praise and a high-five.

Kids were compared to a group that got no feeding program.

After four weeks the praise group accepted three times more bites than the no-treatment group.

Average food list grew from 4 to 11 items.

No child gagged or cried during meals.

Parents said mealtime stress dropped by half on a short survey.

Kirkwood et al. (2021) got even bigger gains when they added escape extinction—removing the spoon only after the bite was swallowed.

Their kids had the same feeding refusal, but the extra step cut problem behavior to zero.

Chen et al. (2022) asked: do kids prefer one bite = one prize, or save-up tokens for a bigger prize later?

They found some kids like instant praise, others like saving up—so assess, don’t assume.

Van Arsdale et al. (2024) reviewed 15 recent studies and saw the field now mixes positive reinforcement with non-contingent snacks or extinction; praise alone is becoming the first layer, not the whole cake.

You can start fixing severe food refusal tomorrow with simple praise and a bite plan—no fancy gear needed.

If the child still spits or screams, layer in extinction or check reinforcer timing using the Kirkwood and Chen blueprints.

Always track acceptance bite-by-bite; the AT data show change shows up fast when you count.
