To validate a Japanese version of the Gastrointestinal Quality of Life Index (GIQLI) in patients with symptomatic gallstone disease.
We investigated responsiveness, reliability, and convergent validity of the translated GIQLI in patients who underwent elective laparoscopic cholecystectomy. Questionnaire scores were compared with the Gastrointestinal Symptom Rating Scale (GSRS) to verify convergent validity.
There were 120 patients originally enrolled in the study; three were excluded after their surgery as they no longer met the inclusion criteria. Questionnaires were collected from the remaining 117 patients (100% response rate). At 2 weeks post-surgery, total GIQLI score increased significantly from pre-surgery levels, suggesting high responsiveness. Cronbach's alpha ranged from 0.901 to 0.934 for the total score, while a comparison of scores at 2 vs 6 weeks post-surgery yielded an intraclass correlation coefficient of 0.843; thus, the Japanese version of the questionnaire was reliable. Correlations with GSRS ranged between -0.459 and -0.679, indicating fair to good convergent validity.
The Japanese GIQLI had high responsiveness and reliability to assess how surgery for symptomatic gallstone disease influenced patient quality of life.
验证日本版的胃肠道生活质量指数（GIQLI）在有症状胆结石疾病患者中的有效性。
我们调查了接受择期腹腔镜胆囊切除术患者中翻译后的GIQLI的反应性、可靠性和收敛效度。将问卷得分与胃肠道症状评定量表（GSRS）进行比较以验证收敛效度。
最初有120名患者纳入研究；3名患者术后因不再符合纳入标准而被排除。从其余117名患者中收集了问卷（回复率100%）。术后2周，GIQLI总分较术前水平显著增加，表明反应性高。总分的Cronbach's alpha系数在0.901至0.934之间，而术后2周与6周得分的比较得出组内相关系数为0.843；因此，该日文版问卷是可靠的。与GSRS的相关性在-0.459至-0.679之间，表明收敛效度良好。
日本版GIQLI在评估有症状胆结石疾病手术对患者生活质量的影响方面具有高反应性和可靠性。
