Psychometric properties of the French version of the TCI-125 in peer-report assessments

Many theories of personality have emerged, but currently, only dimensional approaches seem able to fully capture the complexity of this concept. The Cloninger psychobiological model is organized according to temperament and character from a psychobiological perspective that these variables would be related to individual differences. This model is evaluated by the Temperament and Character Inventory (TCI). Unfortunately, most of versions of this inventory are in the self-report form. Thus, these inventories cannot be used in a certain number of cases, especially in situations where the subjects cannot respond by themselves. This presentation describes the psychometric properties (internal consistency reliability, structural validity, concurrent validity, interrater reliability and test-retest reliability) of the French TCI-125 in peer-report form or hetero-questionnaire (TCI-125-HQ). Studies have shown satisfactory properties for internal consistency reliability, test-retest reliability and concurrent validity of the TCI-125-HQ. Temperament factorial analysis found a structure in three factors and not four, as in the theoretical model. Interrater reliability highlighted that the character dimensions seemed harder to assess compared with temperament dimensions, by the close entourage. The TCI-125-HQ will be useful when subjects cannot answer the TCI in self-report form because they have neurocognitive disorders, in particular, memory impairment or language disorders.
