OBJECTIVE
The aim of the present study was to validate a Swedish translation of the Gastrointestinal Quality of Life Index (GIQLI) questionnaire in patients with gallstone disease.
METHODS
Sensitivity to change, internal consistency, and test-retest stability were tested in 187 consecutive patients who underwent planned cholecystectomy. Construct validity was assessed by comparing the GIQLI score with the bodily pain scale of SF-36 and four single-item questions in a separate group of 104 patients.
RESULTS
A significant increase in all five domains as well as in the overall GIQLI score 6 months after surgery (all P < 0.05) was seen. All five domains correlated significantly with other measures of gallstone-related symptoms except one single-item question. Intraclass correlations ranged from 0.62 to 0.87. Cronbach's alpha ranged from 0.77 to 0.89.
CONCLUSION
The Swedish translation of GIQLI has a high validity and reliability for assessing the impact of gallstones on quality of life.
目的
本研究旨在验证用于评估胆结石疾病患者生活质量的《胃肠道生活质量指数》（GIQLI）问卷的瑞典语翻译版本。
方法
对187例计划接受胆囊切除术的连续患者进行了变化敏感性、内部一致性和重测稳定性测试。在另一组104例患者中，通过将GIQLI评分与SF-36身体疼痛量表以及四个单项问题进行比较，评估结构效度。
结果
术后6个月，所有五个领域以及GIQLI总分均显著增加（所有P<0.05）。除一个单项问题外，所有五个领域均与胆结石相关症状的其他指标显著相关。组内相关系数范围为0.62至0.87。克朗巴哈系数范围为0.77至0.89。
结论
GIQLI的瑞典语翻译版本在评估胆结石对生活质量的影响方面具有较高的效度和信度。
