Validation study of Occupational Stress Injury Resiliency Tool

Reasons for the study

There is an increasing interest from many stakeholders across Ontario, Canada and across the world to better understand leading indicators of work-related psychological/mental injury. Leading indicators can be defined as measures (ideally modifiable) that can be used to identify groups that are at increased risk of an injury outcome in the future. The Occupational Stress Injury Resilience (OSIR) Tool was created to assess first responders’ occupational stress injury risks, with a focus on assessing risk so that targeted preventative actions at the workplace to support mental health could be undertaken. While preliminary work has been undertaken to assess the reliability and validity of the OSIR, additional work still needs to be completed so that workplaces can feel confident in their use of this measure. Further research questions include those on the longitudinal validity of the OSIR and on the performance of OSIR compared with other leading indicators of psychological injury.

Objectives of the study

  • Undertake additional analysis of existing OSIR data and suggest areas where the tool may be improved.
  • Compare the OSIR to other leading indicators of psychological injury.
  • Examine how OSIR scores predict new psychological injuries that occur over a 12-month period.
