Σύνοψη	The International Physical Activity Questionnaire (IPAQ) is a standardized self-report measure of physical activity developed by the International Society for Physical Activity and Health in 2003. Available in short (7 items) and long (31 items) forms, it assesses moderate-to-vigorous and light physical activity across work, transportation, household, and leisure domains. It has become the standard global physical activity assessment tool.	The Health Assessment Questionnaire Disability Index (HAQ-DI) is a 20-item self-report measure of functional disability developed by Fries and colleagues at Stanford University in 1980. Originally designed for rheumatoid arthritis, the HAQ-DI has become the gold-standard functional assessment instrument across diverse rheumatic diseases and chronic conditions.	The Patient-Reported Outcomes Measurement Information System (PROMIS) is a comprehensive, flexible system of patient-reported outcome measures developed by the National Institutes of Health. Launched in 2010, PROMIS measures health across multiple domains using both fixed-item forms and computer-adaptive testing (CAT). It has become the gold standard for outcomes measurement in clinical trials and health systems research.
