Overanxious disorder: a review of its taxonomic properties

The taxonomic properties of overanxious disorder are reviewed using the diagnostic criteria and other features listed in the DSM-III-R manual as a template. The data suggest that overanxious disorder is only a modestly reliable, distinct and valid taxon, and that adjustments to the diagnostic items and criteria and improved sources and methods of data capture are needed. Such changes should be on the basis of empirical data. Since these data are not yet extant, better psychometric-type studies are needed, coupled to assessments of validity. Recently, there has been a distinct increase in number and quality of studies. Although some adjustments are needed, to alter overanxious disorder too much in DSM-IV could make past studies of doubtful relevance and could force a fresh start instead of building on current knowledge.
