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 as a personality disorder, the diagnosis is included under the section “personality disorder not otherwise specified”.

While depressive personality disorder shares some similarities with mood disorders such as dysthymia, 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.

The DSM-IV defines depressive personality disorder as "a pervasive pattern of depressive cognitions and behaviors beginning by early adulthood and occurring in a variety of contexts." Depressive personality disorder occurs before, during, and after major depressive episodes, making it a distinct diagnosis not included in the definition of either major depressive episodes or dysthymic disorder. Specifically, five or more of the following must be present most days for at least two years in order for a diagnosis of depressive personality disorder to be made:

People with depressive personality disorder have a generally gloomy outlook on life, themselves, the past and the future. They are plagued by issues developing and maintaining relationships. In addition, studies have found that people with depressive personality disorder are more likely to seek psychotherapy than people with Axis I depression spectrums diagnoses.
