Research Interests
Dr. Gray is an epidemiologist and health systems researcher at the HSR Seattle-Denver Center of Innovation and a Research Assistant Professor in the Department of Health Services at the University of Washington School of Public Health. She has two broad research interests: understanding and improving Veterans’ health behaviors, particularly physical activity and diet, and women’s reproductive health care delivery. Dr. Gray has a 5-year HSR Career Development Award to develop and pilot test a videoconference-delivered, partner-assisted intervention to improve weight management outcomes among men and women Veterans who are overweight or obese. She also leads an HSR Research to Impact for Veterans project to optimize women’s reproductive health care coordination during VA’s transition to the Cerner electronic health record Dr. Gray received her PhD and MS in epidemiology from the University of Washington School of Public Health and completed a post-doctoral fellowship at the Seattle-Denver Center of Innovation.

Telehealth-delivered peer support to improve quality of life among Veterans with multimorbidity
Role: Co-PI with Katherine Hoerster
Multimorbidity is common among Veterans and results in poor health-related quality of life (HRQoL). It contributes to high health care utilization and costs. Patients with multimorbidity need to engage in self-management for many of their chronic conditions. Patients with multimorbidity experience significant barriers to self-management. Due to the limitations of traditional primary care visits, they need additional support to engage in self-management optimally. Peer support delivered by trained Veteran peer health coaches is well-suited to fill this need.
Limited research has evaluated the effectiveness of peer support in multimorbidity. The proposed study seeks to assess whether a telehealth-delivered peer health coaching intervention improves HRQoL compared to usual VA care among high-risk patients with multimorbidity.
It also aims to understand barriers and facilitators to implement the program in VA if it is effective. This research may enhance VA’s ability to provide services to Veterans with multimorbidity and improve health outcomes.

Enhancing social support for diabetes self-management among men and women Veterans
Diabetes affects 25% of Department of Veterans Affairs (VA) patients. It requires extensive self-management, including healthy eating, being physically active, and taking medications. However, Veterans' self-management is often suboptimal.
Enhancing the quality of existing social support resources is a promising strategy, as most self-management occurs outside the clinical setting.
Therefore, the proposed research will adapt and pilot test a virtual intervention that includes Veterans and support persons and aims to reduce unsupportive (e.g., criticism) and enhance supportive behaviors to facilitate Veterans' self-management.
The research will determine whether the intervention is feasible and acceptable to Veterans and support persons and leads to improved behaviors. Women tend to have poorer self-management, disease control, and health outcomes than men and receive less social support. Examining gender differences, ignored too often in VA interventions, will also be explored.
