Development of a brief version of the Autism Detection in Early Childhood.

Yong-Hwee and team trimmed the full Autism Detection in Early Childhood down to five quick items. They watched toddlers aged 12-36 months during play and scored yes or no on: responds to name, social smiling, gaze switch, follows a verbal command, and uses gestures.

The whole check takes about two minutes and needs no toys beyond what is already in the clinic room.

The mini-screen caught 81 out of every 100 toddlers later diagnosed with ASD. It also correctly cleared 78 out of every 100 children who did not have ASD.

Those numbers match the accuracy of many longer tools, but with a fraction of the items and time.

Bong et al. (2021) got similar sensitivity with their BeDevel tool, but they added a caregiver interview and a 15-minute play session. The ADEC brief shows you can reach the same hit rate with only direct observation, saving about 20 minutes.

Dudley et al. (2019) stretched brief screening into underserved communities by using pictures instead of words. Their Developmental Check-In achieved 75 % accuracy, proving a five-item format can work across literacy levels.

Dietz et al. (2006) ran the ESAT on 14-15-month-olds and found early flags are possible even before the first birthday. Yong-Hwee’s study widens that window up to three years and shows five items are still enough.

Hampton et al. (2015) meta-analysis warned that parent-report tools often miss kids with subtle social issues. The ADEC brief sidesteps that problem by watching the child directly, lining up with the meta-analysis call for stronger social-interaction items.

You can fold this two-minute scan into any intake without extra staff or toys. If a toddler fails two or more items, move them to full assessment and start parent education right away. The short format also fits busy medical visits, letting you screen while waiting for the doctor and catch kids who might otherwise sit on a wait-list for months.
