Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and Cloninger's Temperament and Character Inventory Revised (TCI-R): a comparative study.

The aim of this study was to compare the psychometric properties (normal distribution values, reliabilities and factor structure) of the Zuckerman-Kuhlman-Aluja Personality Questionnaire (ZKA-PQ) and the Temperament and Character Inventory revised (TCI-R). The total sample consisted of 482 subjects (53.1% men and 46.9% women) from diverse age. Results showed somewhat better psychometric properties, like reliability and facet-factor structure, for the ZKA-PQ than the TCI-R. The expected five-factor facet structure of the ZKA-PQ was clear found. However, the seven-factor structure of TCI-R was not clear and it did not show a clear distinction between Temperament and Character factors. When ZKA-PQ and TCI-R variables are analyzed together, the ZKA-PQ factors are related to the Character as well as the Temperament factors. In some cases they represent the opposite poles of ZKA-PQ factors; for example, Neuroticism versus Self-Directiveness and Aggression versus Cooperativeness. Some are directly and highly related to ZKA-PQ factors; for example, Sensation Seeking and Novelty Seeking, Extraversion and Reward Dependence, Neuroticism and Harm Avoidance, and Activity and Persistence.
