Personality traits – relatively stable, enduring patterns of how individuals behave, feel, and think – are regarded as among the most important antecedents of expatriate cross-cultural adjustment (Shaffer, Harrison, Gregersen, Black, & Ferzandi, 2006). For example, personality traits are argued to be more important determinants of cross-cultural adjustment than skills,knowledge, and abilities (SKAs) (Leiba-O’Sullivan, 1999) because they enable expatriates to cope with stress and make sense of their environment (Caligiuri, 2000a). However, surprisingly few scholars have used established psychometric scales to examine the influence of expatriate personality traits on cross-cultural adjustment (for exceptions, see e.g., Huang, Chi, &Lawer, 2005; Shaffer et al., 2006; Van Oudenhoven, Mol, & Van der Zee, 2003). In previous studies, expatriate personality traits are often measured through the Five-Factor Model of Personality (Big Five) (McCrae & Costa, 1987).
