The Depressive Personality Disorder is not yet recognized by the DSM Committee. It makes its appearances in Appendix B of the Diagnostic and Statistical Manual, titled "Criteria Sets and Axes Provided for Further Study." It is not clear in what way is the Depressive Personality Disorder different to other depressive illnesses, such as Dysthymic Disorder.
The Depressive has pervasive and continuous depressive cognitions (thoughts) and behaviors. They manifest themselves in every area of life and never abate. The patient is gloomy, dejected, pessimistic, overly serious, lacks a sense of humor, cheerless, joyless, and constantly unhappy. This dark mood is not influenced by changing circumstances.
