Personality profiles and exercise behaviour across adulthood

Abstract

Personality has constituted a significant psychological component predicting physical exercise. Prior research mostly focused on how personality domains are associated with exercise behaviour. Yet, focusing more closely on combinations of personality domains may be valuable in the future. The present cross‐sectional study aimed to bridge this gap by investigating the associations between Big Five personality profiles and exercise behaviour based on a person‐centred approach in adults. Data from the China Family Panel Studies (CFPS) were used (N = 28,304), in which participants reported their Big Five personality and exercise behaviour. Latent profile analyses, grounded in young adulthood, middle adulthood, and later adulthood sub‐samples, identified five personality profiles: moderate, reserved, confident, resilient, and vulnerable. Across three age groups, significant differences between the five personality profiles in relation to exercise behaviour were revealed. Individuals with the resilient or confident profiles generally had longer exercise duration while people with the vulnerable profile tended to exercise less. Our findings give greater insight into the relationship between exercise and personality, suggesting that different combinations of personality traits may determine individuals' exercise behaviour. It opens promising avenues for identification of adults at risk of lacking exercise, and for development of personality‐targeted exercise interventions.
