Comparison of Psychobiological Personality Model and Five Factor Personality Theory in Turkish sample

Objective: The aim of this research was to compare these two personality theories in the dimensional sense and to determine their relations, overlapping and correlative predictions. Methods: The sample of this study consisted of 200 healthy volunteers. One hundred and twelve participants were male and their old were changed from 18 to 63. The sample was constituted according to snowball sampling method. Temperament and Character Inventory (TCI) and Five Factor Personality Inventory (FFPI) were used for data collection. Results: Except for the self-transcendence dimension, all dimensions of both theories are highly related over the level of 0.40, with at least one dimension of the other theory. According to regression analyzes 37-60% of FFPE dimensions’ variance was predicted by TCI dimen-sions and 3-60% of TCI dimensions’ variance was predicted by FFPI. Discussion: Nevertheless, these relations not indicate exactly overlapping, so two of personality theory’s dimensions include unique properties in themselves.
