How is IWQOL-Lite used?
IWQOL-Lite is used to measure a patient’s weight-related quality of life. This instrument is typically used to provide objective patient psychological data regarding mental status before, during, and/or after obesity treatment. This data can be used as positive reinforcement for the patients, providing them with information outside of physiological measurements to assess the effectiveness of an obesity treatment protocol. IWQOL-Lite has also been extensively used in obesity research assessing the effectiveness of various treatment protocols, devices, surgical techniques and in pharmaceutical clinical trials. IWQOL may also be used to provide weight related quality of life measures for patients being treated for co-morbid conditions such as cardiovascular disease and/or diabetes.
