American newspaper journalists (N = 906) participated in a study examining a cognitive mediational model for explaining the relationship between exposure to work-related traumatic events and work-related posttraumatic stress disorder (PTSD). Results indicated (a) greater exposure to work-related traumatic events was associated with work-related PTSD symptoms, as well as negative cognitive schemas; (b) cognitive beliefs partially accounted for PTSD symptoms, but the full cognitive mediational model was not supported. Implications include targeting interventions for journalists who experience traumatic stress and modifying theories about PTSD symptoms in journalists.
