This study explores the occurrence of PTSD and major depressive disorder (MDD) in victims of armed robbery and evaluates the impact of PTSD on occupational functioning and the use of health care services. Participants in the study were victims of armed robbery, recruited from a major convenience chain in Canada, and assessments were made within days of the robbery and at one month and six months after the robbery. Six participants met PTSD criteria at the one month and/or six month assessment and these were compared with the fifty-nine participants who did not develop PTSD. It was found that the number of days of absenteeism related to the robbery and the number of medical visits was greater among individuals with PTSD. However, the prevalence of PTSD and MDD in this study is considerably lower than the reported prevalence of PTSD following exposure to a traumatic event in the general young adult population. It is suggested that victims of armed robbery may have specific protection factors preventing the development of PTSD and further study is recommended.
