Description
Summary:This group of studies describes the development of a 200 item, self-report, 4-point true-false inventory (Coolidge Axis II inventory [CATI]) to assess personality disorders according to the criteria established in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987). The 13 personality disorder scales of the CATI had a mean test-retest reliability of .90 and a median internal consistency (Cronbach's alpha) of .76. There was a 50% concordance rate with clinician's diagnosis for 24 personality disordered patients. The median concurrent validity (raw score sums) between the CATI and the Millon Clinical Multiaxial Inventory-II for the 13 personality disorder scales was .58. Preliminary studies also support the reliability and validity of Depression, Anxiety, and Brain Dysfunction scales.
