Diagnostic Accuracy of International Epidemiology Network (INCLEN) Diagnostic Tool for Autism Spectrum Disorder (INDT-ASD) in Comparison with Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5)

To compare the diagnostic accuracy of INCLEN Diagnostic Tool for Autism Spectrum Disorder (INDT-ASD) against Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) for the diagnosis of Autism Spectrum Disorder (ASD). 118 children aged 2-9 years with symptoms suggestive of ASD were assessed by INDT-ASD and DSM-V by trained personnel. ASD diagnosis by INDT-ASD was compared against the expert's DSM-5 diagnosis. INDT-ASD had a sensitivity and specificity of 100% and 75%, respectively against DSM-5 for the diagnosis of ASD; specificity for Autistic Disorder was 87%. The INDT-ASD has a good sensitivity and specificity against DSM-5, and can continue to be used for the diagnosis of ASD even after the adoption of DSM-5 criteria.
