Abstract

Aim: Gastrointestinal quality of life index (GIQLI) was initiated in Germany. The aim of this study was to validate its French version (translation).

Methods: The questionnaire includes 36 items asking about symptoms, physical status, emotions, social dysfunction, and effects of medical treatment. The questionnaire has been applied to 615 persons: 335 healthy individuals and 280 patients. Responsiveness and absolute and relative scores were calculated in both groups. Psychometric analysis was done by measuring the validity (convergent and discriminant) and internal consistency.

Results: The responsiveness was 93%. The mean score was 126 for healthy individuals and 96 for patients (P < 0.00001). The validity of the questionnaire (both convergent and discriminant) and the internal consistency were demonstrated. Clinical validity was also suggested by the differences between healthy individuals and patients.

Conclusion: This study allowed the psychometric validation of the French version of GIQLI. This index could be used in France as a reliable method for measuring quality of life related to gastrointestinal diseases.
