[en] The Temperament and Character Inventory (TCI) is a 226-item self-questionnaire developed to assess the seven dimensions of personality described by Cloninger and his colleagues. Normative data from 322 representative French-speaking subjects from Belgium are presented and the psychometric properties are discussed. Mean scores of temperament dimensions were appreciably different from those published by Cloninger. In our sample, novelty seeking and self-transcendence scores were lower and harm avoidance scores were higher compared to US norms. The other dimensions were almost identical. The factorial analysis showed that the hypothesized factor structure of temperament and character dimensions was almost confirmed. The present study also confirmed that the TCI scales were weakly related among themselves. The relationships were consistent with those reported by previous reports. Gender differences were also found for different dimensions.
