Relationship of interpersonal sensitivity with dimensions of the Temperament and Character Inventory in healthy subjects

The relationship of interpersonal sensitivity measured by the Interpersonal Sensitivity Measure (IPSM) with the 7 dimensions of the Temperament and Character Inventory (TCI) was studied in 481 healthy subjects. The multiple regression analysis showed that the IPSM scores were correlated with the scores of 5 dimensions of the TCI, and the correlations were especially strong with self-directedness (β = −.35) and harm avoidance (β = .29). In the principal component analysis of the IPSM combined with the TCI dimensions, the IPSM formed a group with self-directedness and harm avoidance, with respective loading values of 0.82, −0.83, and 0.69. The present study suggests that interpersonal sensitivity is related to some dimensions of the TCI, especially with low self-directedness and high harm avoidance.
