Mental health in the workplace

Workplaces play a dual role in the area of mental health. On the one hand, they can be a stressful environment that contributes to mental health problems among workers. On the other hand, they can play an important part in helping to detect and manage mental health problems when they arise among workers, and in ensuring the healthy recovery and return of workers who are off work due to a mental health issue. IWH research in this area helps paint a clearer picture of the prevalence of mental health problems among workers, the types of labour force and workplace factors that may contribute to poor mental health, and the workplace-based and system prevention efforts that can help improve the mental health of workers and ensure they have the proper supports when needed.

PTSI treatment program delivers benefits for first responders, but no change in return-to-work rates

First responders face high rates of post-traumatic stress injuries (PTSI) due to the nature of their jobs. In response, the Workplace Safety and Insurance Board commissioned an intensive, 14-week program treatment program tailored to these workers, which has undergone a multi-part evaluation.

Preventing and managing work-related psychological injuries in Canada and Australia

As work-related psychological injuries continue to increase, both in number and costs compared to physical injuries, interest has also been growing about different approaches across jurisdictions to prevent and manage these conditions. An Institute for Work & Health team recently conducted a modified environmental scan across 22 jurisdictions in Canada and Australia. In this presentation, lead researcher Dr. Peter Smith shares the results from this project. He also outlines other relevant research from IWH on psychosocial work factors and challenges in return to work for work-related psychological conditions.

System-level approaches to prevent and manage psychological injuries in Canada and Australia

Work injury prevention and workers’ compensation agencies in Canada and Australia have a growing interest in approaches to prevent and manage work-related psychological injuries. This is due to the increasing number of these conditions, and their greater wage replacement and health-care costs compared to physical injuries. Despite this interest, there have been few formal comparative overviews of approaches taken to prevent and/or manage these types of injuries across different jurisdictions.

The objective of this project was to explore the extent to which workers’ compensation systems provide coverage for different types of psychological injuries; the strategies both workers’ compensation systems and occupational health and safety (OHS) prevention agencies adopt to address psychosocial exposures in the workplace both before and after injuries occur; and the benefits, challenges and other outcomes of each of these strategies from the perspective of those working in these jurisdictions. The findings from this project will be of interest to policy-makers in other jurisdictions, both within Canada and Australia, and more broadly.

PTSI treatment program delivers benefits for first responders, but no change in return-to-work rates

First responders face high rates of post-traumatic stress injuries (PTSI) due to the nature of their jobs. In response, the Workplace Safety and Insurance Board commissioned an intensive, 14-week treatment program tailored to these workers. A multi-part evaluation of the program, conducted in part by IWH, has found that participants did not show improvements in return-to-work rates. However, most participants stuck with the program for the full duration, and a quarter saw symptom improvements.

Lower injury rates found when workers feel their workplace prioritizes their wellbeing

Workers who feel their workplaces are not committed to their mental wellbeing have more than twice the risk of work-related physical or mental health injuries compared to workers who feel the opposite. That’s according to an IWH study that asked workers about the psychosocial safety of their workplace—that is, whether an organization prioritizes mental health and wellbeing, and takes action to prevent psychosocial hazards. The study found that poor psychosocial safety and poor physical safety both increase the risk of work-related mental and physical injuries.

Understanding PTSI program implementation processes in Alberta first responder organizations

Post-traumatic stress injuries (PTSI) are common among police, firefighters and paramedics, leading to high rates of work disability in first responder organizations. Growing recognition of this problem has led these organizations to develop and implement PTSI disability prevention policies and programs. In this presentation, Dr. Dwayne Van Eerd shares findings from interviews conducted with first responders in Alberta. He discusses themes that emerged from implementation experiences, highlighting successes and challenges.
