Structure of the DSM-IV personality disorders as revealed in clinician ratings
The revisions proposed for the DSM-5 would greatly alter how personality pathology is
conceptualized, assessed, and diagnosed. One aspect of the proposed changes,

The revisions proposed for the DSM-5 would greatly alter how personality pathology is conceptualized, assessed, and diagnosed. One aspect of the proposed changes, elimination of four current personality disorders, has raised considerable controversy. The present study attempts to inform this debate by exploring clinicians’ views of the structure of Personality Disorders using the current diagnostic system, the DSM-IV. An exploratory factor analysis was conducted on the DSM-IV Personality Disorder criteria using clinician ratings for 280 patients. The factor analysis revealed eight clear and meaningful factors. The eight factors contained all six personality disorders proposed for retention in DSM-5 but also contained clear representations of two disorders (Paranoid and Schizoid) identified for removal from the system. These conditions appear to have clinical utility and their removal may have unintended negative consequences in clinical practice. Dependent and Avoidant criteria also merged to form a new construct with interesting clinical implications. These findings provide new insights into the complex typologies clinicians employ when applying the DSM-IV system to personality disordered patients. Lastly we argue that successful refinement of clinically significant constructs, like diagnostic systems, requires a balanced appraisal of evidence for clinical utility as well as external and internal validity.
