Authors' recommendations: Evidence-based guidelines have recommended the use of the DSM-IV-TR and/or IDC-10 diagnostic criteria for ASD diagnosis. The guidelines were inconsistent in their recommendations regarding the use of ASD screening and diagnostic tools, with three guidelines advocating for tool use in conjunction with clinical judgment and the other one recommending against tool use. The Checklist for Autism in Toddlers (CHAT) tool, along with clinical judgment, was the only screening tool recommended by all three guidelines advocating for tool use. In conjunction with clinical judgment, the Autism Diagnostic Interview-Revised (ADI-R), the Autism Diagnostic Observation Schedule (ADOS)/Autism Diagnostic Observation Schedule General (ADOS-G), and the Childhood Autism Rating Scale (CARS) were the recommended tools for use when diagnosing ASD in those guidelines advocating their use.
