Xenophobia, being hostile to foreigners and feeling fear of them, is considered as hating and having prejudices against the people of other nations. It is noticed that with the increase of migration movements on a global scale in recent years, xenophobia has become one of the more critical subjects in the scientific world. Determining the relationships between xenophobic attitudes and personal traits is considered as one of the important steps in developing relationships especially among people from different cultures. By detecting positive personality traits and negative personality traits associated with xenophobia, interpersonal relationships can be developed. Accordingly, in the current study, it is aimed to determine the relationships between xenophobia and personality traits (neuroticism, extraversion, openness to experience, agreeableness and conscientiousness, and Machiavellianism, narcissism and psychopathy). For this purpose, data were collected from 422 (342 females, 80 males) university students via the data collection tools, which are “Xenophobia Scale”, “Adjectives Based Personality Test” and “Dirty Dozen Scale”. The data were analyzed by stepwise regression technique. As a result of the analyzes, it has been observed that agreeableness, which is among the five-factor personality traits, and psychopathy and narcissism, which are among the dark triad-personality traits predicted xenophobia significantly. Accordingly, it was determined that the agreeable people had lower levels of xenophobic attitudes. Psychopathy and narcissism personality traits have been observed to lead to higher levels of xenophobic attitudes.
