This is a graphic of the Oregon TWH Alliance

The Oregon Total Worker Health Alliance was formed in 2017 between OHWC's home, the Oregon Institute of Occupational Health Sciences, Oregon OSHA, and SAIF (Total Worker Health Affiliate). A flagship effort of the Alliance is the Total Worker Health Curriculum for practitioners. The training continues to be delivered widely. Visit the Alliance page to learn more.

An image of Portland city backdrop

Among other things, COVID-19 has brought with it a whirlwind of new regulations, fast-moving changes, and unforeseen challenges at the workplace. Launched in February 2021, the COVID Conversations is an online series geared toward sharing current practices with occupational health nurses, industrial hygienists, and safety professionals.  Every other week, Outreach Director, Dede Montgomery chats with a safety/health professional to learn how they navigate the pandemic in their organization as they strive employee well-being. The Conversations are recorded and posted to our YouTube channel. 

Total Worker Health Alliance

We launched the Oregon Total Worker Health Alliance in 2017, the first TWH statewide alliance and a regional partnership between Oregon OSHA, SAIF (Oregon’s major worker compensation insurer) and the Oregon Institute of Occupational Health Sciences/OHWC.  A flagship effort of the Alliance has been the TWH curriculum for practitioners and professionals, including approval by the American Society of Safety for Total Worker Health 101: The Basics to receive CEUs as an ASSP Professional Development Course.

Your An Oregon Healthy Workforce Center Resource website was released as a one-stop online source for organizations to gain access to OHWC research products and materials, housing toolkits (SHIP, PUSH, COMPASS, BeSuper) and access to outreach products (Health Impacts Safety meeting guides, Oregon and the Workplace Blog, What’s Work Got to Do With It? Podcast). Join in on YourWorkpath Tour monthly drop-in sessions on the last Tuesday of each month from 9 to 10AM PST to learn more about OHWC resources.

Ship Program

The Safety and Health Improvement Program (SHIP) toolkit developed by  Drs. Leslie Hammer and Donald Truxillo provides online training, templates, and guides for supervisors and managers to help improve the safety, health, and well-being of employees. The toolkit has been shown in research studies to (1) reduce stress and work-life conflict, (2) increase team communication and effectiveness, (3) improve employee health and safety, and (4) enhance work processes and practices. The SHIP toolkit user guide was updated in the Summer of 2020 and is currently being adapted for use by SAIF corporation for distribution to its policyholders.

Compass Program in conjunction with Oregon Home Care Commission (OHCC)

The Oregon Home Care Commission (OHCC), a study partner of the COMPASS study adopted the COMPASS program for home care workers in 2017, an intervention turned toolkit developed by Dr. Ryan Olson. The Commission and OHWC continued partnership has helped produced an online training for facilitators who will implement the program, as well as a roll out for a new version of the program’s guidebooks adapted to personal support workers.

Be Super! in Construction

Be Super, A Total Worker Health® intervention developed by Dr. Kent Anger and conducted in four Oregon-based construction companies, led to increased family-supportive supervisory behaviors, team cohesion sleep duration and exercise, and decreased sugary drink and snack consumption and systolic blood pressure. The BeSuper toolkit was updated in January 2020.

Active Workplace Study: How an intervention that uses the Total Worker Health approach can impact sedentary behavior and improve worker health and safety

The Active Workplace Study, led by Dr. Brad Wipfli, recruited call centers and their employees to participate in a randomized controlled trial to determine how an intervention that uses the Total Worker Health approach can impact sedentary behavior and improve worker health and safety. 

Tech4Rest: A study to assess how an environmental and individual level intervention can impact outcomes related to fatigue and improve Total Worker Health and well-being.

The Tech4Rest Study (led by Drs. Ryan Olson and Pete Johnson) is assessing how engineering (mattress and seat enhancements) and behavioral (sleep and health program) controls might benefit team truck drivers’ sleep, health, and well-being. Recently published pilot study results showed that a therapeutic mattress altered patterns in whole body vibration exposures, was beneficial for drivers’ sleep, and universally preferred over standard coil spring mattresses. The addition of an active suspension seat and behavioral sleep and health program produced further improvements in sleep and fatigue outcomes. 

What's Work Got To Do With It: A workplace safety, health, and well being podcast

The OHWC and Oregon Institute of Occupational Health Sciences’ podcast, What’s Work Got To Do With It?  has released 16 podcast episodes. This podcast helps inform  the community on how work can affect safety, health, and well-being, discuss public health significance of occupational health, and makes science accessible for all through sharing of basic and applied science.

Sample Affiliate Project Accomplishments

Affiliate projects are led by investigators at the Oregon Institute of Occupational Health Sciences and are not funded by OHWC's NIOSH Center of Excellence grant. However, like OHWC projects, they focus on issues relevant to Total Worker Health, the design of work, and worker well-being.

Veteran Supportive Supervisor Training (VSST) was developed by Dr. Leslie Hammer and used to evaluate 40 organizations across the state of Oregon, demonstrating that when civilian supervisors went through the training it improved their positive attitudes toward service members.

Interventions that utilize the positive influence of safety champions, including a recently completed pilot study of effective worker-led programs to improve occupational health and safety in nurses, are developed by Dr. David Hurtado.

A project to develop and validate a Total Worker Health Climate Scale with the goal of facilitating organizational assessment and improvement of TWH culture is being proposed by Dr. Emily Huang’s Safety Climate Lab.

Mental Health Awareness Training (MHAT), one of the first scientifically evaluated mental health training programs for workplace leaders to demonstrate ROI, was developed and implemented by Affiliate Faculty and OHWC Occupational Mental Health Advisor, Dr. Jennifer Dimoff.

Metrics are updated in January and June of each year.
