OBJECTIVE: To explore the psychometric characteristics of a modified version of the Cloninger's personality questionnaire, the Temperament and Character Inventory-Revised (TCI-R). METHOD: A 482-subject sample, including clinical and non-clinical subjects, completed the TCI-R. We performed principal component analyses and explored the factorial structure of the questionnaire, and the internal consistency of each dimension. RESULTS: The factorial structure of the TCI-R was well defined as expected and similar to those shown with the TCI. Robust factors were obtained for Reward Dependence and Persistence in the TCI-R, even more clearly than in the original TCI. All dimensions obtained higher alpha Cronbach coefficients with the TCI-R than with the TCI. We obtained highly satisfying reliability coefficients in test-retest and TCI/TCI-R comparisons. CONCLUSION: The TCI-R seems to have similar psychometric and feasibility characteristics as those of the initial version, but with significant improvements in terms of factorial structure and internal consistency of most dimensions.
