The Depressive Personality Disorder Inventory: An initial examination of its psychometric properties

Abstract

A 41-item questionnaire was developed to assess cognitions that are representative of the DSM-IV conceptualization of depressive personality disorder. Eighty-nine undergraduates from a private, Midwestern, Catholic university were administered the Depressive Personality Disorder Inventory (DPDI), the Dysfunctional Attitude Scale (DAS), and the Automatic Thoughts Questionnaire-Revised (ATQ-R). Results indicated that the DPDI is internally consistent, assesses a single construct, and has construct validity relative to the DAS and ATQ-R. Given these promising initial findings, continued use and refinement of the DPDI are warranted.
