Emergency workers, including urban fire fighters and paramedics, must cope with a variety of duty-related stressors including traumatic incident exposures. Little is known about coping responses of emergency workers or whether their coping responses predict future mental health outcomes. The previously formulated Coping Responses of Rescue Workers Inventory (CRRWI) underwent a principal components analysis employing a sample (N = 220) of urban fire fighters and paramedics. Six empirically and theoretically distinct CRRWI components were identified which were relatively stable over a 6-month period. Scores on one of the CRRWI scales, but neither years of service nor their past half year's traumatic incident exposures, predicted future changes in self-reports of posttraumatic stress symptomatology.
