咽喉反流症状指数量表中文版的信度及效度评价

Chinese version of the reflux symtom index was evaluated for reliability and validity

目的探讨中文版咽喉反流症状指数（Reflux symtomindex，RSI）量表的信度、效度及临床价值。方法自行引进并将RSI量表翻译成中文。门诊接受中文版RSI量表评估患者107例，其中疑诊患咽喉反流性疾病（1aryngopharyngeal reflux disease，LPRD）者72例，非疑诊者35例，1周后均再次填写量表。疑诊患者中的41例和非疑诊患者中的13例（共54例）接受24h咽喉pH检测。经pH检测确诊LPRD患者34例，其中30例给予药物治疗，3个月后再次填写RSI量表。结果RSI量表内部一致性信度分析Cronbaeh’s0／．系数为0．715；重测信度采用Spearman相关分析，各条目及总分的相关系数为0．750—0．971。以pH检测作为诊断LPRD的金标准，RSI量表诊断符合率66．7％，阳性预测值80．8％；区分效度采用两个独立样本Wilcoxon检验，RSI总分比较Z=-3．266，P=0．001，差异有统计学意义。LPRD患者治疗前后自身对照符号秩和检验，各条目与总分的P值均〈0．05，差异均有统计学意义。结论RSI量表中文版具有良好的信度和效度，可作为LPRD诊断的初筛，也可用于LPRD患者治疗后评估疗效的辅助工具。

Objective To investigate the reliability, validity and clinical value of Chinese version of the reflux symptom index（RSI）. Methods xThe Chinese version of RSI scale was used in ENT outpatient department. There were one hundred and seven patients, including thirty-five patients with common throat diseases （non-suspected） and seventy-two patients with clinically suspected throat reflux. All 107 patients were asked to complete the two scales one on the first-visiting and one after one week. Thirteen patients with common throat diseases （non-suspected） and forty-one with suspected throat reflux also received RSI testing. Among the thirty-four confirmed acid reflux disease patients, thirty patients received pharmaceutical treatments and self-performed post-RSI testing after three months. Results The RSI Scale internal reliability consistency included the test-retest reliability（0. 715-0.971 ） , discriminant validity and construct validity. RSI total targeting percentage was 66.7% , targeting percentage was 80.8%. Discriminant validity was confirmed using 2 independent samples Wilcoxon test, with RSI total score compared to Z = - 3. 266, P = 0. 001. The before and after treatment self-control ehi-square test （ P 〈 0.05 ）, the difference was statistically significant. Conclusion RSI Simplified Chinese version has good reliability and validity, and can be used for laryngopharyngeal reflux disease （LPRD） diagnostic screening along with the efficacy for the treatment of patients with appropriate LPRD aids.
