Problems with the psychosis section of DSM-5

Abstract

The psychosis section of DSM-5 contains a number of changes from DSM-IV. These are mostly minor and there is no reason to expect any significant change in diagnosis or treatment as a result of the changes in the diagnostic criteria or the text. The psychosis section of DSM-5 contains errors in logic, oversights, and inconsistencies, however, and these should be addressed in future editions of the manual. The definition of delusions and the difference between a delusion and an obsession are particularly problematic.
