As a social and health psychologist, Dr. Gruenewald’s research focuses on the mind-body processes that play a role in healthy aging during older adulthood. A particular interest is understanding how older adults’ perceptions of their social usefulness and value affect their mental and physical well-being in later life. Her research has shown that older adults who feel more useful to others live longer and with better cognitive and physical functioning as they age. Her current work is exploring the psychological and biological pathways through which feeling useful promotes better health, as well as the activities and interventions that encourage feelings of usefulness in later life. Along with a team of investigators at Johns Hopkins University and UCLA, she is exploring whether participation in the intergenerational program, Experience Corps, which brings together older adult volunteers and young schoolchildren, leads to better mental and physical well-being in older adults and better academic and psychosocial outcomes in children. Dr. Gruenewald also explores the biological pathways that underlie connections between psychosocial factors and healthy aging. Her research examines methods for assessing dysregulation across multiple biological systems in the body, based on the theory that social and psychological factors affect many biological processes. As part of this research, she explores methods for measuring allostatic load, a multi-system index of biological functioning, and the impact of psychosocial stressors and resources on the development of allostatic load in later adulthood and subsequent risk of poor health.
