Abstract
It has been suggested in personality and emotion theories that traits can influence emotional states and behaviour through interpretive processes such as cognitive appraisals. The present study investigated the relationships between Big Five personality dimensions and the cognitive appraisal processes associated with challenge and threat states in a large sample of municipal firefighters. The study assessed the Big Five traits and cognitive appraisal tendencies using a new measure of challenge‐threat appraisal that measured appraisals directly and aggregated both across stressful situations and within six specific stressor domains. The results indicated that the Big Five traits related to overall challenge‐threat appraisal and their accompanying primary and secondary components in unique and compelling ways, with some traits related more strongly to primary appraisals of situational demands and others related more to secondary appraisals of coping abilities. Overall, the results provide insights into how personality traits are associated with stress‐related emotional experiences.
