The purpose of this study was to investigate a diathesis-stress model, focusing on narcissistic personality. Participants were 174 college students, 72 men and 102 women. They completed Narcissistic Personality Inventory 35 (NPI-35; Konishi, Okawa, & Hashimoto, 2006), in addition to scales of stressor, stress response, and happiness. About one month later, the same stressor, stress response and happiness scales were administered again. Hierarchical multiple regression analysis showed that men with high narcissistic personality significantly increased scores on subscales of depression and heightened activity of autonomic nervous system if they had experienced stressful events. In contrast, women high on the trait with stressful events showed an increase in feeling of fatigue. These findings indicated that narcissistic personality was a vulnerability factor to stress.
