262 The evaluating life course stress experience (ELSE) Scale: A novel age-correlated life course stress screening measure

Abstract

Objectives/Goals: Chronic stress may accelerate biological aging yet is often overlooked in clinical settings. Many tools to assess stress exist, but a comprehensive measure of cumulative stress across the lifespan is unavailable. This study validates a novel measure of lifetime stress for use as a screening tool in clinical practice. Methods/Study Population: Patients (n > 220) enrolled in brain health research registry at the Washington University St. Louis Knight Alzheimer Disease Research Center completed in-person surveys at baseline and after six months. Baseline measures included the everyday discrimination scale (EDS), total adverse experience (TAE), and demographics. Age and evaluating life course stress experience (ELSE) scores were measured six months later. Ongoing analysis includes age-adjusted correlations of ELSE scores with TAE and EDS scores. We will investigate the correlation with race and ethnicity and sex assigned at birth. We will explore the relationship between ELSE score and multidimensional intersectionality. Results/Anticipated Results: The sample was 87% Black or African American, 8% White, 4% Hispanic, 82% female, and 18% male, with a mean age of 66 ± 10 years. Age-adjusted relationships between patient characteristics and ELSE scores will be analyzed. Additionally, ELSE responses will be compared against age, EDS, and TAE measurements. Intersectionality between race-ethnicity, sex, and gender will be examined. We hypothesize ELSE scores will vary by demographic. Preliminary results indicate the ELSE scale correlates with established life stress measures, accounting for cumulative stress exposure across a lifespan independent of specific stressor topics. Discussion/Significance of Impact: The ELSE scale is a viable tool for clinical screening of chronic stress exposure over a lifespan. Its implementation will allow clinicians to identify patients at high risk for accelerated aging, facilitating targeted interventions and advancing equity in healthcare delivery.
