Psychometric properties of a brief inventory for the screening of personality disorders: The SCATI.

The purpose of the present study was to report on the psychometric properties of a revised version of a brief inventory designed to screen and assess personality disorders. The short form of the Coolidge Axis II Inventory (SCATI) is a 70-item, self-report, form of the 250-item Coolidge Axis II Inventory (CATI). On a community sample of 588 adults (range=16-88 years), the median internal scale reliability for the 14 personality disorder scales was .66, and the median test-retest reliability (1 week) was .83. Principal components analysis (PCA) revealed a four-component structure, essentially similar to previous PCA studies of the SCATI and CATI. Good convergent validity was obtained between a five-factor model of psychopathology and the 14 SCATI personality disorder scales. Gender differences were obtained on some scales, although the effect sizes were generally small. These preliminary psychometric properties establish that the SCATI has sufficient reliability and validity to warrant further research, particularly in clinical samples.
