The Roles of Daily Stressor Control and Social Determinants of Health in Executive Function and Episodic Memory Performance

Abstract

AbstractBackgroundStudying modifiable psychosocial contributors to Alzheimer’s disease and related dementias (ADRD) is crucial to inform approaches for ADRD prevention, especially among those with less education, lower neighborhood quality, and heightened discrimination. These three social determinants of health confer increased ADRD risk. Perceived control is an important psychosocial resource for cognitive health. Most prior work, however, focuses exclusively on global aspects of control, ignoring influences of more dynamic aspects of control over specific experiences in daily life, such as daily stressor control.MethodWe used data from the Midlife in the United States study and the National Study of Daily Experiences (N = 1,651, Mage = 62.09, SE = 12.11, 56.65% Female) to address this gap and examine the roles of daily stressor control and social determinants of health in cognitive performance. Over 8 consecutive days in the second and third waves of data collection, respondents reported their perceived control over stressors they had experienced. Respondents also completed assessments of education, neighborhood quality, perceived discrimination, and a telephone‐based battery of tests measuring executive function (EF) and episodic memory (EM). We employed multilevel modeling to assess associations of daily stressor control and social determinants of health with cognitive performance.ResultEF was higher among people with more education and those with less perceived discrimination (ps<.001), but was not related to daily stressor control (p>.05). Greater daily stressor control, more education, and better neighborhood quality was related to better EM (ps<.05). A stressor control by discrimination interaction showed that greater stressor control was associated with better EM among those with comparatively less perceived discrimination (p<.01).ConclusionDaily stressor control may serve as a psychosocial resource for cognitive health, but the strength of its relationship with cognitive performance varied by perceived discrimination. Promoting stressor control may be beneficial for cognitive health among those with comparatively less perceived discrimination, but more research is needed to clarify psychosocial resources that could buffer against the impacts of heightened discrimination on cognitive health disparities in the US. Future work should examine longitudinal relationships to clarify the predictive utility of stressor control for cognitive health and the daily mechanisms that may explain these associations.
