Investigating the Role of Personality Traits on the Mental Health of the Residents of China: How Effective is the BIG Five?

Personality Traits in Latin America: A Cross-Cultural Study of the Big Five Factor Structure and its Relationship with Self-Reported Daily Behaviors

The Big Five factors model of personality is one of the most internationally studied and applied since it has been replicated in multiple investigations in different countries and cultures. This five-dimensional structure has evidence from studies carrying out factor analyses in different versions and adaptations of personality measurement instruments under these theoretical assumptions, and cross-cultural studies reveal its universality. However, no research has investigated how this structure is replicated in Latin American countries yet. This study aimed to carry out a cross-cultural study evaluating the factorial congruence of the Revised International Personality Item Pool in Latin American countries. The validity was also analyzed assessing relationships with gender, age, and self-reported activities of daily living. The five-dimensional structure was supported by evidence in the different samples that participated in this study, preserving the individual differences that characterize each country. Differences according to gender and age were found in different personality factors, as well as relationships with recreational activities. It is concluded that the five-factor structure of the scale is replicated in Latin American samples and that the psychometric properties of the instrument are consistent. Limitations and future lines of research are discussed.

BACKGROUND

Sub-health can have an impact on the physical condition of the young adults, and this study aimed to investigate the influencing factors of sub-health related to the Big Five personality in Chinese young adults.

A total of 6165 young adults were included in this study. The results of the mediation analysis indicated that sleep quality partially mediated the relationship between neurotic, extraversion, agreeableness, and conscientiousness of young adults and sub-health. Family health played a moderating role between the sleep quality and agreeableness of young adults.

LIMITATIONS

CONCLUSION

Family health and sleep quality can influence sub-health in Chinese young adults with different personality traits.
