Predicting the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition): The Mystery of How to Constrain Unchecked GrowthBlashfield, Roger K. PhD; Fuller, A. Kenneth MDJournal of Nervous & Mental Disease: June 2016 - Volume 204 - Issue 6 - p 415–420 doi: 10.1097/NMD.0000000000000491 Original Articles Abstract Author Information Abstract: Twenty years ago, slightly after the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition was published, we predicted the characteristics of the future Diagnostic and Statistical Manual of Mental Disorders (fifth edition) (Blashfield and Fuller, 1996). Included in our predictions were how many diagnoses it would contain, the physical size of the Diagnostic and Statistical Manual of Mental Disorders (fifth edition), who its leader would be, how many professionals would be involved in creating it, the revenue generated, and the color of its cover. This article reports on the accuracy of our predictions. Our largest prediction error concerned financial revenue. The earnings growth of the DSM’s has been remarkable. Drug company investments, insurance benefits, the financial need of the American Psychiatric Association, and the research grant process are factors that have stimulated the growth of the DSM’s. Restoring order and simplicity to the classification of mental disorders will not be a trivial task. *Auburn University (Professor Emeritus), Auburn, AL; and †Department of Psychiatry and Health Behavior, Medical College of Georgia, Augusta, GA.
