Background: International estimates suggest that up to one in three public safety personnel experience one or more mental disorders, including post-traumatic stress disorder (PTSD). Canadian data have been sparse until very recently, and correctional officers and forensic psychiatric staff have rarely been included. Working as a correctional officer is associated with negative health outcomes and increased work-related stress, with several variables affecting reported levels of stress. Healthcare staff also report higher rates of PTSD, especially those who are exposed to aggression in their workplace. In the present study, we compare current symptoms of diverse staff working in correctional occupations.
