A convergent validity study of Cloninger's Temperament and Character Inventory with the Coolidge Axis II Inventory.

This study examined the convergent validity of the Temperament and Character Inventory (TCI), a measure of four biosocial temperaments and three character dimensions with the Coolidge Axis II Inventory (CATI), a measure of 14 personality disorders. A nonclinical sample of 163 college students was given both measures, and the data were analyzed with bivariate and multivariate statistics. Hypotheses generated from the findings of Svrakic, Whitehead, Przybeck, and Cloninger (1993, Archives of General Psychiatry, 50, 991-999) were confirmed for a majority of the relationships between the two measures. The preliminary results provide qualified support for the TCI and Cloninger's biosocial theory in the assessment of personality disorders.
