Using measures from the SCL-90-R to screen for personality disorders

Abstract

Objective: The Symptom Check-List 90-Revised (SCL-90-R) is a widespread instrument in clinical practice. Does it also contain useful screening properties with respect to DSM-IV) personality disorders (PDs)? Methods: SCL-90-R questionnaires from 2248 patients admitted for treatment in the Norwegian Network of Personality-Focused Treatment Programs were analysed with respect to associations between the Interpersonal sensitivity, Hostility and Paranoid ideation subscales, and avoidant, borderline and paranoid PD, as well as the Personality Severity Index (PSI) and its relationship to severe or any PD. Results: The three 'interpersonal' subscales and the SCL-90-R PSI displayed significant but modest associations with the associated DSM-IV personality disorders. However, the associations and the diagnostic efficiency statistics were not strong enough for diagnostic inferences. Conclusion: Although the SCL-90-R is primarily a measure of symptom distress, it yields some valid supplement in assessing the extent of present interpersonal dysfunction, and may serve as an indicator for further diagnostic evaluations. © 2010 John Wiley & Sons, Ltd.
