Abstract
OBJECTIVE
Patients with gastric tumor are known to have deterioration in quality of life (QOL) following surgery. However, there is no valid disease-specific self-report QOL measure for clinical practice and research designated for Chinese in Hong Kong. The current study aimed at translating and validating a Chinese version of the Gastrointestinal Quality of Life Index (C-GIQLI) for use in patients with gastric tumors after gastrectomy.
METHODS
A translation of the English version of the instrument was performed. The psychometric properties of the C-GIQLI were investigated using internal consistency analysis, correlational analysis, and confirmatory factor analysis in 140 Chinese patients who had undergone surgery for gastric tumor.
RESULTS
The C-GIQLI demonstrated good test-retest reliability, internal consistency, and a factor structure consistent with the measurement model of the European version of the instrument.
CONCLUSION
The C-GIQLI is recommended as a valid and reliable self-report measure of QOL in patients with gastric tumor after gastrectomy.
