Samenvatting	The PDQ-39 is the most widely used patient-reported outcome measure for Parkinson's disease quality of life. Developed by Crispin Jenkinson and colleagues in 1997, this 39-item self-report questionnaire comprehensively assesses how Parkinson's symptoms affect daily functioning, emotional well-being, stigma, social support, and cognitive-communication abilities. It is the recommended instrument in major Parkinson's disease clinical trials and forms a core component of outcome measurement in movement disorders.	The FIQ is the most widely used patient-reported outcome measure for fibromyalgia disease burden. Developed by Cynthia Burckhardt and colleagues in 1991, this 10-item questionnaire quantifies how fibromyalgia affects physical function, work capacity, depression, anxiety, sleep, pain, and fatigue. The revised version (FIQR, 21 items) offers enhanced psychometric properties and is the current standard in fibromyalgia clinical trials and practice.
