Introduction: Cloninger's biopsychosocial model suggests the eight configuration types of temperament combining high or low score of Novelty Seeking (NS), Harm Avoidance (HA), or Reward Dependence (RD) temperament dimensions, and each type has different level of immaturity calculated as sum of Self-Directedness (SD) and Cooperativeness (CO) character dimensions. Objectives: The aim of present study was to investigate whether the eight temperament types would exist and the immaturity level of eight temperament types could be replicated in Asian culture. Methods: 527 Korean college students (195 males and 332 females) were recruited from the Busan metropolitan area, and their temperament types and immaturity levels were acquired by using Temperament and Character Inventory (TCI). Results: The ratio of immature person varied from 4.2% of reliable/staid type (low NS, low HA, and high RD) to 74.6% of explosive/borderline type (high NS, high HA, and low RD) and showed the similarity of Western culture. However, the percent of adventurous/antisocial temperament type (high NS, low HA, and low RD) was found to be 23.5% unlike previous reports of 48% in Western culture. Conclusions: Asian people are regarded as more collectivistic and less individualistic and therefore, those with adventurous/antisocial temperament type tend to behave more conformative to social norms, resulting in less maladaptive and immature character. Both universal and distinctive properties of temperament types considering the importance of sociocultural contexts were discussed for the future research. [ABSTRACT FROM AUTHOR]
