Three diagnostic systems for autism: DSM-III, DSM-III-R, and ICD-10

Abstract

ICD-10 draft research criteria for childhood autism were applied to a previously published data set comparing DSM-III and DSM-III-R to clinicians' diagnoses of autism. The ICD-10 approach paralleled clinicians' patterns of diagnosis and, to a lesser extent, the DSM-III system. Relative to either clinicians, DSM-III, or ICD-10 the DSM-III-R system overdiagnosed the presence of autism. Implications for research and for future revision of diagnostic criteria are discussed. © 1992 Plenum Publishing Corporation.
