The Interpersonal Circumplex Model forms the theoretical basis of the paper, which explains the behaviour of the individual in interpersonal relationships and the Big-Five Personality Model, which implies the existence of five basic dimensions of personality. The paper aimed at examining the predictive power of the domain of the interpersonal circumplex model in predicting personality traits of youth in Kosovo and Metohija. The sample consisted of young people aged 18 to 26 studying at these three faculties (Faculty of Philosophy, Faculty of Economics and Faculty of Law) at the University of Pristina with temporary head office in Kosovska Mitrovica. The following instruments were used to collect the data: The Interpersonal Questionnaire (IPQ-S 76) and the Big Five Inventory (BFI). Results of the regression analysis show that the interpersonal circumplex model is significant in predicting extraversion, openness, conscientiousness, and pleasantness, and the percentage of variance explaining personality traits ranges from 16 to 40%. The following variables were singled out from the group of predictor variables: (non) Fearfulness and Extraversion in Extraversion Prediction; Assertiveness, Belonging/Attachment, and (non) Manipulativeness in Predicting Openness to Experience; (non) Equanimity in predicting conscientiousness; (non) Assertiveness and (non) Reservation as well as Belonging in predicting pleasantness. Young people who are assertive, sociable and warm-hearted, are characterized by optimism, cordiality, openness to change and new experiences. The findings obtained are in harmony with some previous studies that showed that the interpersonal circumplex model contributes substantially to predicting extraversion and pleasantness.
