As a high risk, physically demanding, and stressful profession, firefighting presents an ideal context for the study of hardiness. Hardiness of professional Spanish firefighters was assessed. Participants (53 firefighters; M age = 36.1 yr., SD = 8.2) volunteered to complete the adapted Spanish version of the Personal Views Survey. Results showed that participants' mean Hardiness score was slightly high. Hardiness was influenced by years of service. Spanish firefighters present a homogenous set of personal characteristics related to managing stressful working circumstances. The effect of experience on Hardiness levels is discussed.
