Current research projects
Oregon Healthy Workforce Center
Dr. Hammer is the Co-Director of the Oregon Healthy Workforce Center, one of ten Total Worker Health® Centers of Excellence funded by the National Institute for Occupational Safety and Health (NIOSH). Research at the OHWC focuses on effective interventions that aim to improve the health, safety, and wellness of workers. Read more about the Oregon Healthy Workforce here
Department of Defense Projects
The next three research projects in this section were all funded by the Department of Defense, starting in 2013 to the present. Dr. Hammer and her team built on the Family Supportive Supervisor Behavior training, created with Dr. Ellen Kossek, and adapted the content for specific types of supervisor support in various military settings. Each project used a rigorous study design, a randomized controlled trial, and focused on employee outcomes of health and well-being, as well as organizational effects. We partnered with Drs. Cynthia Mohr and Todd Bodner at Portland State University.
Each project has its own study website which you can find by clicking on the hyperlinked title.
Readiness Supportive Training for Leaders (RESULT): 2018 – 2023
RESULT involved the development and evaluation the effectiveness of our Readiness Supportive Leadership Training (RESULT) with active duty U.S. Army soldiers. The training program has had a positive impact on service member readiness and resilience, psychological health, team cohesion, and reduced loneliness. This research was designed to benefit not only U.S. Army soldiers, but service members across all military branches, as well as first-responders and other civilian occupations that face highly stressful situations as part of their work. Read more about the project on the Oregon and the Workplace blog.
The Oregon Military Employee Sleep and Health Study (MESH): 2016-2022
The MESH Study addressed the issue of sleep-related health concerns that are increasingly the focus of research in the military, as well as in the civilian sector. The adverse effects of sleep deprivation are known to cause a variety of negative health and family issues. We partnered with the Oregon National Guard to conduct this study.
We created a Family and Sleep Supportive Training for ORNG leaders and also gave individual sleep feedback to participants. Findings thus far show the MESH Training has a positive impact on sleep health, general well-being and improved work outcomes, such as higher job satisfaction and safety behaviors, as well we reduced turnover intentions. Even though they were not directly involved in the training, spouses and partners also benefited with improved couple and individual well-being effects. For more detail on these findings, as well as to experience the training program, please visit the MESH Study website.
SERVe aimed to improve the health and well-being of service members and their families by targeting the workplace experiences of Veterans and Service Members recently transitioned to the civilian workforce. For the SERVe Study, Dr. Hammer and her team created an online training for supervisors of veteran employees to improve the knowledge and skills of supervisors with service members in their employ to foster a supportive workplace environment.
The SERVe training and behavior tracking programs are available at the SERVe website, along with summaries of research findings.
Past Research Projects
The Safety & Health Improvement Program (SHIP) was designed to increase supervisor and peer support and decrease job strain, which play a key role in safety compliance and improved physical and mental health. SHIP integrates a focus on both health protection and health promotion by addressing psycho-social factors that are shown to be related to safety, well-being, and organizational productivity.
The SHIP intervention study was a NIOSH-funded randomized controlled trial focusing on supervisors and their teams. SHIP aimed to increase employee support from supervisors, improve team communication, enhance team effectiveness, and reduce stress and work-family conflict.
The SHIP intervention was composed of:
- One-hour training for supervisors
- Behavior-tracking that reinforced the training principles
- Team-based planning and problem-solving that utilizes a modified version of WFD Consulting's Team Effectiveness Process
- Follow-up sessions
SHIP has been systematically revised to apply across a wide variety of industries and organizations . The revised SHIP training is now available to implement in your organization.

The Sandwiched Generation
Along with her colleague Dr. Margaret B. Neal, Dr. Hammer researched the modern phenomenon of working couples who care for both children and aging parents and coined them the "Sandwiched Generation". Her research still guides evidence-based practices aimed at improving the health and well-being of these couples.
Work, Family & Health Network (WFHN)
The Work, Family & Health Network (WFHN) is comprised of an interdisciplinary team of researchers brought together by The National Institutes of Health and the Centers for Disease Control and Prevention to advance the field of workplace psychosocial interventions in order to improve the health of workers and their families, while benefiting employers.
