Abstract Purpose The RAND-36 is the most frequently used patient-reported outcome measure (PROM) to evaluate health-related quality of life (HRQoL) in bariatric surgery. However, has never been adequately validated purpose this study was validate Dutch patients undergoing Material and Methods To RAND-36, following measurement properties were assessed surgery patients: validity (the degree which measures what it purports (HRQoL)), reliability extent scores are same for repeated who have not changed HRQoL), responsiveness ability detect changes HRQoL over time). Results Two thousand one hundred thirty-seven included. Validity adequate due irrelevance some items response options, lack relevant surgery, did actually intended (HRQoL patients). Reliability insufficient majority scales had different when RAND completed a second time (intraclass correlation coefficient (ICC) values 0.10–0.69)). Responsiveness insufficient. Conclusion supported by sufficient validation evidence means that does patient population. Future research studies should use PROMs specifically designed assessing Graphical abstract
