Rationales, values, and DSM-IV: The case of ''medication-induced movement disorders''

The DSM-IV has improved psychiatric diagnostic classification through initiating, among other things, the open disclosure of rationales for nosologic changes. It will be argued that a consideration of values is necessary in justifying nosologic changes, considerations missing from the DSM IV rationales. In illustration of this, I examine the reasons for including the medication-induced movement disorders (MIMDs) on axis I by using a literature review, then compare the published rationales for including the MIMDs with the DSM IV Task Force's own guidelines for including categories. Discrepancies are found between the Task Force's guidelines for including categories and the published rationales for including MIMDs. Strict adherence to the Task Force guidelines more strongly supports placing MIMDs in axis III, Discussion emphasizes the importance of value commitments in nosology development.
