Screening for personality disorder with the Standardised Assessment of Personality: Abbreviated Scale (SAPAS): Further evidence of concurrent validity

Abstract

Background: The assessment of personality disorders (PD) is costly and time-consuming. There is a need for a brief screen for personality disorders that can be used in routine clinical settings and epidemiological surveys. Aims: To test the validity of the Standardised Assessment of Personality: Abbreviated Scale (SAPAS) as a screen for PD in a clinical sample of substance abusers.Methods: Convergent validity of the SAPAS with both categorical and dimensional representations of personality disorders was estimated.Results: In this sample, the SAPAS correlated well with dimensional representations of cluster A and C personality disorders, even after controlling for ADHD symptoms, anxiety/depression symptoms and recent substance use. The SAPAS was also significantly associated with total number of PD criteria, although correlation with categorical measures of PD was weak.Conclusions: The SAPAS is an valid brief screen for PD as assessed dimensionally. © 2010 Hesse and Moran; licensee BioMed Central Ltd.
