About IWQOL-Lite-CT​©


The IWQOL-Lite Clinical Trials Version© (IWQOL-Lite-CT©) was developed for use in the context of clinical trials for obesity, addressing concerns that are specifically relevant to these participants. The 20 items in this instrument cover the full range of concerns in this population (i.e., has content validity) and the items are easily understood and consistently reported as salient and likely to change with 10% weight loss. The IWQOL-Lite-CT© has the potential to support labeling claims, as it was developed and validated in accordance with the Food and Drug Administration’s “Guidance for industry; Patient-reported outcome measures: use in medical product development to support labeling claims, December 2009.”
