Psychobiological model of temperament and character: Validation and cross-cultural comparations

Džamonja-Ignjatović Tamara, Knežević Goran

The paper presents research results regarding Psychobiological model of personality by Robert Cloninger. The primary research goal was to test the new TCI-5 inventory and compare our results with US normative data. We also analyzed the factor structure of the model and the reliability of basic TCI-5 scales and sub-scales. The sample consisted of 473 subjects from the normal population, age range between 18-50 years. Results showed significant differences between Serbian and American samples. Compared to the American sample, Novelty seeking was higher in the Serbian sample, while Persistence Self-directedness and Cooperativeness were lower. For the most part results of the present study confirmed a seven factor structure model although some sub-scales did not coincide with basic dimensions as predicted by the theoretical model. Therefore certain theoretical revisions of the model are required in order to fit in the empirical findings. Similarly, the discrepancy between the theoretical and empirical was also noticed regarding the reliability of TCI-5 scales. They also need to be re-examined. Thus the results of the study showed satisfactory reliability of Persistence (.90), Self-directedness (.89) and Harm avoidance (.87), but low reliability of the Novelty seeking (.78), Reward dependence (.79) and Self-transcendence (.78).
