Hypothesis
The objective was to validate a new self-administered questionnaire specific to morbid obesity to be used in clinical trials.
Conclusion
The Laval Questionnaire is a valid measure of health-related quality of life in patients with morbid obesity and is responsive to treatment-induced changes.
Supporting Evidence

- Significant differences in score changes were observed between patients who underwent surgery and those who did not.
- The questionnaire was developed based on patient input regarding quality of life impacts.
Takeaway

Limitations
The study was conducted in a single institution and may not represent all patients with morbid obesity.
