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

  • The Laval Questionnaire showed moderate-to-high correlations with established quality of life measures.
  • 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

The Laval Questionnaire helps doctors understand how morbid obesity affects people's lives and can show if treatments are working.

Methodology

The study involved comparing the Laval Questionnaire scores with other established questionnaires at baseline and after one year.

Limitations

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