01Research in Context

01

What this study did

Thomas et al. (2023) asked parents to run a 30-second safety scan before entering any new room. They wanted to see if this quick habit could stop kids with developmental delay from putting harmful items in their mouths.

The study used a single-case design. Parents marked a short checklist each time they moved to a new place. No extra staff or clinic visits were needed.

02

What they found

Pica attempts dropped to near zero once parents used the checklist. The gains stuck when families visited new places and faced new objects.

Parents kept using the scan weeks later without prompts. The child stayed safe even when the room held tempting items like coins or paper clips.

03

How this fits with other research

Thomas et al. (2023) also tested a teen with autism. That study used a bigger package: competing items, RIRD, and response cost. Both papers show parents can wipe out pica, but the checklist is far simpler.

Morris et al. (2021) ran a brief home-based FA first, then taught a mand for edible items. The checklist skips the FA and jumps straight to prevention. If time is short, you can choose either path.

Buckley et al. (2025) gave caregivers a grooming checklist for young adults. The same checklist logic improved clothing appearance and cut pica. A tiny list can drive big change across very different skills.

Why it matters

You can hand this checklist to any parent today. No extra training, no clinic space, no data sheets. A 30-second scan keeps kids safe in stores, parks, or grandma’s house. If you already run complex pica plans, add the scan as a quick layer of protection that travels everywhere.

03Original abstract

Parents of three children with neurodevelopmental disorders and pica were taught to use a safety checklist to create pica-safe areas when transitioning to new locations. During baseline, no parent displayed pica-safe behavior, and their children attempted pica at moderate to high rates. After use of the checklist, parent pica-safe behavior increased, and instances of pica diminished to near zero. Results transferred to new contexts and additional substances associated with pica. Using the safety checklist appears to have aided parents in creating pica-safe environments to minimize pica.
