Psychopathology in person with and without co-morbid autism
type: CreativeWork
description: Autism and intellectual disability are frequently co-occurring. In addition, a diagnosis of mild, moderate, severe, or profound intellectual disability increases the risk for co-occurring Axis I psychiatric disorders. This study utilized multivariate analyses of variance (MANOVA) to determine whether mean differences exist across three diagnostic groups: ID only, ID and autism, and ID and pervasive developmental disorder not otherwise specified (PDD-NOS) on the linear combination of subscales present on the Diagnostic Assessment of the Severely Handicapped-II (DASH-II), a psychometrically sound measure that assesses psychopathology in those with ID. The results of this study supported an association between the presence of secondary ASDs and the presence of psychiatric and behavioral disorders with those with ASDs displaying more psychopathology than those with sole ID diagnoses.
