Optimism and the Big Five factors of personality: Beyond Neuroticism and Extraversion

The purpose of the present study was to investigate the relationship between the Big Five factors of personality and dispositional optimism. Data from five samples were collected (Total N = 4332) using three different measures of optimism and five different measures of the Big Five. Results indicated strong positive relationships between optimism and four of the Big Five factors: Emotional Stability, Extraversion, Agreeableness, and Conscientiousness. Agreeableness and Conscientiousness explained additional variance in dispositional optimism over and above Neuroticism and Extraversion, providing evidence for the complexity of optimism. The position of optimism in the larger web of human personality constructs is discussed.
