Observational Assistance Publique - Hôpitaux de Paris · NCT06549179

What this trial studies

The study adds an 8‑item French AMSE and a brief scoring guide to the routine pre‑evaluation completed by trained non‑expert psychiatrists or psychologists for adults seeking an ASD diagnostic workup. Seven days to 12 months later, participants undergo a standard two‑day multidisciplinary evaluation at the expert center (Pitié‑Salpêtrière) with a final DSM‑5 diagnosis. The primary goal is to measure the AMSE's diagnostic performance (sensitivity and specificity) when used by non‑experts, against the expert center diagnosis as the reference standard. The protocol is motivated by prior expert‑administered AMSE results showing high sensitivity (0.91) and specificity (0.93) in a small sample, and aims to confirm usability in routine care.

Who should consider this trial

Good fit: Adults (18+) in France who request an ASD diagnostic evaluation, are covered by national health insurance, speak French, and have not already received an ASD diagnosis are the intended participants.

Not a fit: People already diagnosed with ASD, non‑French speakers, pregnant or breastfeeding individuals, those deprived of liberty, patients covered by AME, or cases where the AMSE is not properly completed are unlikely to benefit from this screening approach.

Why it matters

Potential benefit: If successful, the AMSE could reduce unnecessary specialist referrals and shorten waiting times by enabling quicker, accurate pre‑screening of adults with suspected autism.

How similar studies have performed: Previous work using experts showed excellent AMSE sensitivity (0.91) and specificity (0.93) in a small sample, but evidence for its performance when used by non‑expert clinicians is limited.
