The study, published by American College of Occupational and Environmental Medicine, aimed to determine whether the well-being index (WBI) can identify US workers in distress and stratify quality of life (QOL). Workers and physicians were evaluated for efficacy of the WBI and an expanded version of the WBI (eWBI) in identifying individuals with distress — high fatigue, burnout, low QOL, and suicidal ideation — and high QOL. The results show eWBI improved stratification among individuals with low scores on WBI and also identified individuals with high quality of life in both groups. Ergo, the eWBI can be utilized as a screening tool to identify individuals in distress across different domains and identify individuals with well-being.
