Operational stress injury (OSI)
An operational stress injury (OSI) is a persistent psychological difficulty resulting from operational duties performed during military or RCMP service.
It encompasses a range of health problems, including anxiety disorders, depressive disorders, substance use, Post-Traumatic Stress Disorder (PTSD), and other mental health conditions that may vary in severity but can all interfere with daily functioning.
Various experiences can cause operational stress. While active combat is certainly one of them, there are other events associated with the risk of serving in the military or RCMP that can also lead to such injuries. When these experiences significantly disrupt a person's life, they result in an OSI. Additionally, OSIs can produce physical symptoms, such as stomach upset, headaches, and sleep problems, and worsen existing chronic pain issues. Furthermore, an OSI can negatively impact relationships in the person's life.
