Depressive Personality Disorder

Depressive personality disorder (also known as melancholic personality disorder) is a controversial psychiatric diagnosis that denotes a personality disorder with depressive features.

Originally included in the American Psychiatric Association's DSM-II, depressive personality disorder was removed from the DSM-III and DSM-III-R. Recently, it has been reconsidered for reinstatement as a diagnosis. Depressive personality disorder is currently described in Appendix B in the DSM-IV-TR as worthy of further study. Although no longer listed in the manual's personality disorder category, the diagnosis is included under the section “personality disorder not otherwise specified”.

While depressive personality disorder shares some similarities with mood disorders such as dysthymic disorder, it also shares many similarities with personality disorders including avoidant personality disorder. Some researchers argue that depressive personality disorder is sufficiently distinct from these other conditions so as to warrant a separate diagnosis.
