The ASD-DA was adapted and translated into Spanish and administered to a sample of 156 adults with severe (n = 67, 42.9%) and profound (n = 89, 57.1%) intellectual disability. Seventy-one (45.5%) participants had a diagnosis of intellectual disability and autism spectrum disorder, and the other eighty-five (54.5%) had a diagnosis of intellectual disability without autism spectrum disorder. The reliability scores of the scales implied values in the "good-to-excellent" range (0.78-0.95), and test-retest reliability was obtained with good values for most of the items on the scale. A three-factor structure was replicated via confirmatory factor analysis. Participants with and without ASD showed significant differences in the three ASD-DA scales and in their total scores. Using a receiver operating characteristics (ROC) curve, a score of 21 on the ASD-DA scale showed good specificity (0.97) and sensitivity (0.92) values with respect to DSM-IV-TR criteria.18 p.application/pdfeng(c) Springer Verlag, 2017AutismeDiscapacitats mentalsAutismPeople with mental disabilitiesinfo:eu-repo/semantics/article6715802020-05-15info:eu-repo/semantics/openAccess
