ABSTRACT
PURPOSE:
Our objective was to estimate preference-based weights for the IWQOL-Lite that reflect the relative importance overweight and obese people place on the domains included in the instrument.METHODS:
US residents, 18 years of age or older, who are overweight (BMI=25.0-29.9) or obese (BMI>or=30) completed an online survey instrument consisting of 12 choice questions. The survey included eight attributes problems doing usual daily activities, physical symptoms, worry about health, low self-esteem, sexual problems, problems moving around or sitting in public places, teasing or discrimination, and problems at work. Ordered probit was used to estimate importance weights for the attributes and levels.RESULTS:
Five hundred and two subjects completed the survey. Sexual problem was the most important attribute. The remaining attributes can be ranked on the order of importance as follows low self-esteem, physical symptoms, daily activities, teasing or discrimination, moving around or sitting, problems at work, and worry about health.CONCLUSIONS:
Our results confirm previous findings that weighting the individual items in the IWQOL-Lite by the importance of outcomes to overweight and obese subjects may provide a more meaningful evaluation of the effect of changes in weight on patient well-being than a nonpreference-based measure of HRQOL.
