title: DSM-IV Personality Disorders: Dimensional Ordered Categorization and Associations With Disability and Selected Axis I Disorders in a General Population Survey.
abstract: The DSM approach to personality disorder (PD) diagnoses has been criticized for using arbitrary thresholds. The present study evaluated one dimensional approach with ordered threshold categories of severity by examining associations with several measures of disability and Axis I disorders for 10 PDs in the general population. Data were obtained from the National Epidemiologic Survey of Alcohol and Related Conditions, Waves 1 and 2. Respondents were categorized according to PD criteria as follows: "no symptoms" for having no positive criteria, "subthreshold" for having at least one positive criterion but below the DSM-IV threshold, "at-threshold" for meeting the DSM-IV threshold and additionally having one or two more positive criteria, and "suprathreshold" for meeting the DSM-IV threshold plus three or more positive criteria. Findings from this national study provide support for dimensional approaches to diagnostic classifications for the majority of PDs and suggest that mild levels of severity indeed have clinical significance.
