PREVALENCE AND MEDIATING FACTORS OF POST-TRAUMATIC STRESS IN PROFESSIONAL FIRE-FIGHTERS

摘要

Previous studies on Post-Traumatic Stress (PTS) in fire-fighters have typically examined group responses to unusual and traumatic events. In this study, symptoms of PTS were observed in a group of urban Canadian firefighters during routine operations in the context of typical daily work. Participants completed a PTS questionnaire as well as a workplace health questionnaire which assessed environmental and contextual factors in addition to personal health. Elevated levels of PTS were observed in 18.1% of the 105 fire-fighters studied. Those who reported elevated symptoms also reported more concern for financial issues, more worries and more concern about needing physical exercise and support services. These results indicate that emergency response professionals such as fire-fighters can develop elevated levels of PTS in the context of routine work. The findings also suggest that the development of PTS involves a complex relationship between characteristics of stressors, work related variables and other contextual factors specific to the individuals affected. Complex models are needed to account for these types of interactions, particularly in chronically stressful occupational settings. Strategies for mitigating symptoms of PTS are discussed and suggestions for future research are offered.
