Background: It is extremely important to validate psychological (psychometric) tools before use in research projects. In fact without reliable and valid psychological tools, we can not rely on research results. TCI contains subscales designed to measure seven different personality traits and characteristics. This paper presents complementary findings to a previous study. In fact, the aim of this study was to summarize a normative data of TCI for an Iranian sample of men and women with different ages.
Methods: At first all research workers, who collected data in present study, were trained for the skills needed in order to communicate with the participant and to conduct the questionnaire. Randomly selected participants (n=1212) completed TCI questionnaire.
Results: The results showed normative data for the subscales novelty seeking (NS), harm avoidance (HA), reward dependence (RD), persistence (Per), self directiveness (SD), cooperation (Co) and self transcendence (ST) for different gender and age classes.
Conclusions: Similarities and differences of the present findings and other studies will be theoretically discussed. The sample of participants in this study allows us to generalize the collected data. The results shows that now we can benefit from using the questionnaire in Iranian society. Different applications of TCI in various clinical and normal settings will be discussed. The present results is complementary to the previous findings reported in the same journal.
