Cross-cultural psychology as a discipline examines the way that human behavior is different and/or similar across different cultures. One important and widely studied area in this subfield of psychology is personality, particularly the study of Big Five. The Big Five personality traits are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The Big Five model of personality (also known as the Five Factor Model) has become the most extensively studied model of personality and has broad support, starting in the United States and later in many different cultures. However, there is also some evidence which suggests that the Big Five traits may not be sufficient to completely explain personality in other cultures.
Research suggests that the same five-factor structure of personality can be found in multiple other countries, based on a translated version of the Revised NEO Personality Inventory. Over the past decade, studies on the validity of the Five-Factor Model using translations of the Revised NEO Personality Inventory have found broad support across many different studies and in many different countries; in earlier studies, Extraversion and Neuroticism were reported as stable personality scales across several cultures, including German, Dutch, French, Japanese, Chinese, and Filipino samples.
Further research found support for the entire Five-Factor Model in Chinese, Dutch, Italian, Hungarian, German, Australian, South African, Canadian, Finnish, Polish, Portuguese, Israeli, Korean, Japanese, and Filipino samples, in addition to other samples. Across multiple studies, factor analyses of translations of the Revised NEO Personality Inventory in languages from different language families consistently load on five factors that largely correspond to the Big Five personality traits. Additionally, the Big Five traits have been found in the personality ratings of observers in over 50 cultures, indicating that the previous findings were not dependent merely on ratings of the self. Overall, this body of work has established the validity of the Five-Factor model cross-culturally, potentially providing evidence for the Five-Factor Model as a universal taxonomy of personality structure.
