Coolidge (2001) has developed a short-form, the short Coolidge axis-two inventory (SCATI), a 70-item version of the original 225-item Coolidge axis-II inventory (CATI). In a normative study of this instrument, the test was found to have many of the psychometric properties of the original. Multivariate analysis revealed that the internal structure of the SCATI is similar to the original. [ABSTRACT FROM AUTHOR]

The Coolidge Axis-II Inventory (CATI) is a 200-item self-report inventory that is designed to measure DSM-IV personality disorders (PD's). Norms with a sample of 1,790 Canadian college students are compared with a US sample of 573 college students and 36 elderly subjects. Comparisons for the 11 DSM-IV personality disorder scales are made with several age groups and with gender. Some interesting similarities and differences were observed. With the Canadian sample, a gender difference was found on the antisocial scale. Age differences were found for on several PD scales in that younger respondents (17–24 years) scored higher than the older ones (25–57 years). This information is likely to be helpful to clinicians in monitoring age related behavioral changes in personality disorder. [ABSTRACT FROM AUTHOR]
