สรุป	The Impact on Participation and Autonomy (IPA) scale is a validated, patient-centered measure designed to quantify how chronic conditions or disabilities affect an individual's autonomy and participation in five key life domains: autonomy, mobility, occupation, social relations, and recreation. Developed in the Netherlands by Cardol and colleagues, it operationalizes the WHO handicap concept (now called 'participation restriction') and is widely used in rehabilitation, chronic disease management, and policy evaluation across Europe.	WHODAS 2.0 is a standardized, WHO-developed instrument that measures disability and functioning across six core life domains in any population aged 18 and above. Introduced in 2010, it operationalizes the biopsychosocial model of disability using the International Classification of Functioning (ICF) framework, making it applicable to chronic disease, physical injury, mental health, and aging contexts.
