The (Impact of Weight on Quality of Life-Lite-Clinical Trials) is a validated, 20-item patient-reported outcome (PRO) instrument designed to assess weight-related quality of life in individuals with overweight or obesity participating in clinical trials. It is a shortened and optimized version of the original IWQOL-Lite, specifically developed to reduce respondent burden while maintaining robust psychometric properties suitable for regulatory and research settings. The measure captures the impact of weight on physical function, psychosocial functioning, and overall well-being, making it a critical endpoint in obesity pharmacotherapy and device trials.
