The purpose of this paper is to examine the effects of personality traits (big five) on expatriates adjustment and job performance. Design/methodology/approach – In this regards, data were collected from 201 expatriates working in Malaysia and analyzed by using structural equation modelling with Amos 16. Findings – The findings of this study indicated that personality traits (big five) which include extroversion, openness to experience, agreeableness, conscientiousness, and neuroticism positively influence expatriate adjustment which further influence expatriate performance rated by peers. In other words, expatriates adjustment (work, interaction, and general) mediate the relationship between big five personality traits (extroversion, openness to experience, agreeableness, conscientiousness, and neuroticism) and expatriates job performance (task, relationship building, and overall performance). Research limitations/implications – The findings of this study will help the researchers to further understand the importance of personality traits required for successful completion of international assignment. Furthermore, the findings also suggest human resource professionals to consider these personality traits before selecting an individual for international assignment. Finally, future research directions have been proposed. Originality/value – Literature on expatriate adjustment and job performance is still at developing stage. This paper shed light on the individual characteristics which work as predictors for expatriates adjustment and job performance.enExpatriates adjustmentExpatriates job performanceBig fivePersonality traitsArticlehttps://doi.org/10.1108/EDI-01-2013-0001
