Abstract
Significant delay in ASD diagnosis leads to attempts to simplify diagnosis processes. Therefore, there is a need for tools helping to target complex cases to be referred to a tertiary care centers, in order to avoid two-step assessments. We hypothesized that the Autism Mental Status Examination (AMSE) might be of help in this triage. The aim of this study is to assess psychometric properties of the AMSE in a high-risk sample of children referred for a suspected autism spectrum disorder and determine optimal cutoff for ASD classification and cutoffs for triage. Patients referred for an autism spectrum disorder (ASD) focused assessment were included. Developmental history and clinical observation were recorded. Usual diagnostic tools were used. A best-estimate clinical diagnosis (BECD) was determined. The AMSE was scored a posteriori. Internal consistency was 0.611. Concurrent validity was good. The optimal cutoff for a BECD of ASD was 5. Sensitivity reached 1.00 for a cutoff of 3 and specificity for a cutoff of 10. AMSE has good psychometric properties and can be useful for adequate referring towards diagnostic teams of various level of specialization.
