Objective: This study aims to determine Nine Types Temperament Model (NTTM), which is a new temperament model, with Psychobiological Personality Model (PPM) and Affective Temperament Model (ATM) and define the possible relations between categories and dimensions and their degrees of predicting each other. Methods: The sample group consists of 206 healthy volunteers who did not receive any psychiatric treatment in their life and do not have any chronic disease. Structured Clinical Interview for DSM-IV (SCID-I), Structured Clinical Interview for DSM-III-R personality disorders (SCID-II), Temperament and Character Inventory (TCI), Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire Version (TEMPS-A) and Nine Type Temperament Scale (NTTS) were used to collect data. Results: Except for NTM3, NTM8 and NTM9 temperament categories, all NTTS categories have significant correlation with various TCI dimensions at a level r=0.40 and above. Except for NTM1, NTM5 and NTM9 temperament categories, all NTTS categories have significant correlation with various TEMPS-A categories at a level r=0.40 and above. According to the results of regression analyses, it is found that TCI dimensions and TEMPS-A categories can explain 29-63% of variance of NTTS temperament categories. Conclusion: This study indicates that although there are consistent and significant correlations between dimensions and categories of NTTS and the two scales widely used in psychiatry, there are conceptual differences between NTTM, PPM and ATM and temperament categories of NTTM have unique features.
