Temperaments and characters: incompatible or complementary components for criterion B of the alternative model in predicting DSM-5 section II personality disorders?

BACKGROUND: Many studies have found clear correspondence among the domains of the five-factor model of personality (FFM) and the alternative model of personality disorders (AMPD) in DSM-5-III, which is assessed with the Personality Inventory for DSM-5 (PID-5). However, very few studies have compared the PID-5 with the other well-known established dimensional models of personality such as Cloninger’s model. The present study examined whether the Temperament and Character Inventory (TCI-125) dimensions, PID-5 dimensions, or a combination would represent PD-scale scores more accurately. PARTICIPANTS AND PROCEDURE: In this regard, 437 college students completed the Persian version of the PID-5, TCI-125 and SCID-II Screening Questionnaire. RESULTS The results indicated that cooperativeness (low), self-directedness (low), and self-transcendence (high) characters of the TCI-125 and the psychoticism (high) domain of the PID-5 are the most consistent predictors of all PD-scale scores. CONCLUSIONS: Overall, the findings showed that an integrative model, combining dimensions of the TCI-125 and PID-5, represented the features of PD-scale scores most effectively.
