Objective: This study aimed to examine the association between the five factor model of personality and exercise level and self-efficacy (SE) for exercise in older Japanese adults. This study also examined whether SE mediates the association between personality and exercise behavior. Methods: A questionnaire survey was distributed that determined age, sex, physical health, exercise level, SE for exercise, and personality traits of 1,515 older Japanese adults. Of these 1,515 people, 876 aged 60–92 years completed the questionnaire survey. Results: Extraversion and conscientiousness were significantly and positively associated with exercise level after controlling for age, sex, and physical health. All domains of personality traits (extraversion, openness, agreeableness, and conscientiousness were positive, but neuroticism was negative) were significantly correlated with SE for exercise. Structural equation modeling showed that only extraversion was directly affected by exercise level, all personality traits showed significant pathways to SE for exercise, and SE for exercise was the greatest predictor of exercise level in all pathways in the final model. Conclusion: Extraversion is directly associated with exercise level, extraversion, and other personality traits that are affected by SE for exercise. Additionally, SE for exercise is the greatest predictor of exercise level in older Japanese adults.
