Psychosocial Resources and Physiological Dysregulation
Psychosocial resources refer to individual personality and social relationship factors that tend to cluster together and contribute to psychological and physical health and well-being. Growing evidence demonstrates robust relations between psychosocial resources and health. Physiological dysregulation represents one key mechanism that may help to explain the link between psychosocial resources and health. The current chapter focuses on the relations of psychosocial resources with physiology, drawing on findings from the Midlife in the United States (MIDUS) study and other large, epidemiological studies. The focus is on the relations of psychosocial resources with allostatic load, a composite index of multisystem physiological dysregulation, while also highlighting select findings for individual biomarkers. The summary of evidence examines psychosocial resources as both a direct and a moderating factor on biological outcomes. The chapter concludes with suggestions for future research.
