Tóm tắt	The Stanford Presenteeism Scale (SPS-6) is a brief assessment tool measuring work productivity and performance among employees who are present at work despite health problems, personal issues, or other limitations. Developed by Koopman and colleagues in 2002, the SPS-6 quantifies the degree to which an employee's ability to concentrate, accomplish tasks, and maintain efficiency is compromised while working. Presenteeism—working while ill or impaired—is increasingly recognized as a significant occupational health concern with substantial economic and wellbeing consequences.	The Effort-Reward Imbalance (ERI) Scale is an occupational stress assessment tool based on a reciprocal model of work stress. Developed by Johannes Siegrist in 1996, the ERI measures the degree to which employees experience imbalance between their job efforts (demands, overcommitment) and job rewards (income, recognition, career prospects, security). The instrument is grounded in social reciprocity theory and has strong evidence linking high imbalance to cardiovascular disease, depression, and burnout.
