[image omitted] Review of five instruments for the assessment of Asperger's Disorder in adults

Abstract

Due to the recent inclusion of Asperger's Disorder (AD) in the Diagnostic and Statistical Manual of Mental Disorders (APA, 1994) and the International Classification of Diseases (WHO, 1993), concerns regarding diagnosis of AD, particularly in adults, are emerging. Many existing instruments used to assess Pervasive Developmental Disorder are more appropriate for identifying Autistic Disorder (AU) in children, and their usefulness for assessing AD in adults is questionable. We describe and critically review five instruments created specifically for identifying AD in adults. Overall, the normative information provided is limited and evidence of the reliability and validity for each instrument is relatively poor. Further research and development is required before we would recommend one instrument over another for the assessment of AD in adults.
