The Psychometrics of the European Portuguese Version of the Temperament and Character Inventory-Revised

Cloninger’s psychobiological model of personality integrates contributions from behavioral genetics, neurobiology, and psychology in the description of the human personality. The temperament and character inventory (TCI) is its assessment instrument. The Brazilian Portuguese version of the TCI has shown good psychometric properties. However, Portuguese spoken in Brazil presents marked and substantial differences to that spoken in Portugal, and no study has yet described the psychometrics of the European Portuguese version. The objective of this study was thus to describe the psychometric properties of the European Portuguese adult version of the TCI (the temperament and character inventory-revised (TCI-R)). This study involved 1400 Portuguese adult participants. The factorial structure of the European Portuguese version was tested using four methods: exploratory factor analysis, orthogonal procrustes rotation analysis, confirmatory factor analysis, and exploratory structural equation modeling.
