The purpose of this study was to investigate the relationship between hardiness and personality traits, stressors, stress reactivity, and lifestyle. Ninety-two university students completed a questionnaire that measured hardiness, type-A behavior, type-C behavior, perfectionism, optimism, stressors, stress reactivity, and lifestyle. Results showed that persons who possess all three hardiness attitudes (challenge, control and commitment) have adaptable and healthy personality traits and lifestyles. Results also showed that persons who possess only control have a type-A behavior pattern, perfectionism, and unhealthy lifestyle.
