Samenvatting	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.	The KDQOL is the most widely used quality of life measure for chronic kidney disease (CKD) patients, particularly those on dialysis. Developed by Ron Hays and colleagues in 1994, this multidimensional questionnaire (full version 134 items; short-form KDQOL-SF 36 items) measures kidney disease-specific impacts on physical function, emotional well-being, social participation, and treatment burden. It is the standard outcome measure in renal research and clinical practice.
