Σύνοψη	The Work Ability Index (WAI), developed by Tuomi and colleagues at the Finnish Institute of Occupational Health in 1998, is a validated self-assessment instrument measuring the ability to perform work. The WAI comprises seven dimensions: current work ability compared to lifetime best, work ability relative to job demands, number of diagnosed diseases, absenteeism, prognosis, mental resources, and productivity. It is widely used in occupational health surveillance, aging-workforce management, and return-to-work programs.	The Perceived Stress Scale (PSS), developed by Cohen, Kamarck, and Mermelstein in 1983, is the most widely used measure of subjective stress in research and clinical practice. Available in 10-item (PSS-10) and 14-item (PSS-14) versions, the PSS assesses the degree to which individuals perceive situations as unpredictable, uncontrollable, and overwhelming. The scale captures stress as a result of how people interpret and react to life events rather than the events themselves.
