Could a Quick Quiz at Home Help Spot Autism in Kids?

Could a short questionnaire — taken from your living room in about three minutes — one day help flag autism in a child as accurately as a lengthy clinical evaluation? A new study published in JAMA Network Open on July 22, 2026, says maybe. Researchers at UCLA and the University of Chicago have built and tested an experimental tool called CAT-Autism, and the early results are striking enough to be worth explaining in plain language.

Why This Is Needed

Diagnosing autism today usually means a long wait for a specialist, followed by hours of testing. That delay is a real problem, because the earlier a child gets support, the more it can help them. Many kids aren't diagnosed until they're already in school — even though doctors could often tell much earlier.

What's New

Researchers built a short, smart questionnaire called CAT-Autism. A parent answers a handful of questions about their child's behavior — how they talk, play, and interact with others — and the test adjusts as it goes, asking only what it needs to. Most parents were done in about a dozen questions, in roughly three minutes.

Does It Actually Work?

In a study of over 10,000 children, the short quiz was just as accurate as the much longer, traditional questionnaires doctors normally use. It was excellent at catching clear, obvious cases of autism. It was less reliable for milder cases, where signs are subtler and harder for any test to catch cleanly.

One doctor not involved in the study called it a potential "game changer," since it could let far more families and general doctors get a fast, reliable first read — not just a handful of specialists .

The Important Catch

A good score on this test does not mean a child definitely doesn't have autism, especially in milder cases. It's built to work alongside a doctor, not replace one — the researchers themselves stressed that results still need to be discussed with a clinician who can ask follow-up questions and guide what to do next.

It also hasn't been tried yet in real homes or clinics — this was a research study using existing data, not a live pilot. Wider testing is the next step.

Bottom Line

This is encouraging early research, not a finished product. The goal isn't a home test that gives you a final answer — it's a faster first step to help families get connected to the right care sooner. If you ever have concerns about a child's development, the right move is still the same as always: talk to your doctor.
