A survey of autism knowledge in a health care setting.

Dagnan et al. (2005) handed a short quiz to three groups in one hospital: primary-care doctors, specialists, and autism experts at the local CARD center.

The quiz mixed DSM-IV facts with questions about how autism unfolds over time and what treatments help.

Everyone got the checklist items right, but the answers about future outlook and best care split wide between groups.

Primary-care doctors saw a darker future and listed different treatments than the CARD team.

Specialists landed in the middle.

The gap was biggest on items like "will this child talk" and "which therapy works first."

No group flunked the textbook part; the clash came only on real-life next steps.

Roudbarani et al. (2023) asked Ontario therapists if they would accept an autistic client.

Intent was low when knowledge and peer support were weak, showing the same link D et al. found eighteen years earlier.

Hronis et al. (2018) saw Aussie mental-health staff rate their own skill as "okay for talk therapy, shaky for testing or treatment plans."

Together the three surveys trace a straight line: less know-how equals less confidence and less willingness to serve.

Ricciardi et al. (2020) add a bright spot—direct-care staff like data sheets when training is clear—so the fix may be simpler than we think.

Before you send a family back to the pediatrician with a long report, pause.

The doctor may still picture autism as a sentence, not a treatable trajectory.

Attach a one-page visual that shows typical language gains with early ABA and list local providers.

That small step can reset expectations and keep the referral chain moving in the right direction.
