Changes To Cluster C
If depressive personality disorder were added to the DSM-V, it would be included in the Cluster C personality disorders, anxious and fearful personality disorders. At this time, those include avoidant, obsessive-compulsive, and dependent personality disorders. The make-up of Cluster C would have to be rethought, as the figure shown below could no longer represent all of the disorders if depressive personality disorder were to be included. The relation shown in the Venn diagram has been accepted for years and would have to be rethought and redesigned if depressive personality disorder were to be added. Further studies are in progress looking into the comorbidity of Cluster C disorders and depressive personality disorder, as well as how these disorders interact with each other in patients diagnosed with multiple Cluster C disorders.

Famous quotes containing the word cluster:
“Next week Reagan will probably announce that American scientists have discovered that the entire U.S. agricultural surplus can be compacted into a giant tomato one thousand miles across, which will be suspended above the Kremlin from a cluster of U.S. satellites flying in geosynchronous orbit. At the first sign of trouble the satellites will drop the tomato on the Kremlin, drowning the fractious Muscovites in ketchup.”
—Alexander Cockburn (b. 1941)
