Objective: To produce the Chinese version of a new reflux symptom score (RSS) of laryngopharyngeal reflux disease (LPRD) and to evaluate its reliability, validity and clinical value. Methods: This was a retrospective study which contained 42 healthy volunteers and 135 possible LPRD patients. RSI,RFS,oropharyngeal pH monitoring (Dx-pH monitoring) and RSS of each patient were performed. RSS was performed again after 1 week. Confirmed LPRD patients were treated with proton pump inhibitor for 8 week. And RSS was performed again after treatment. Reliability and validity of RSS were evaluated. Results: The Cronbach's α coefficient of RSS was 0.77, which indicated good internal reliability of the new score. The results of test-retest found all P values were less than 0.05, which supported good external reliability. Comparing RSS with laryngopharyngeal reflux test results, the diagnostic coincidence rate was 84.44% (114/135), and the positive predictive value was 85.71% (114/133), which showed good criterion validity. After 8 weeks treatment of PPI, RSS decreased significantly (pretreatment 84.79±42.50,posttreatment 20.11±22.82,t=-10.54, P<0.001), indicating good reactivity of RSS. The score of quality of life impact (Qol) in possible LPRD patients was obviously higher than that of healthy volunteers (t=7.15,P<0.001). All patients and volunteers believed that RSS was a good way to evaluate their symptoms. Conclusions: The new score RSS have good internal and external reliability, criterion validity and reactivity. RSS can be one of the important reference indexes to evaluate LPRD.
目的： 建立咽喉反流性疾病（LPRD）的反流症状评分（reflux symptom score，RSS）量表中文版，评估其信度和效度。 方法： 回顾性分析2020年11月—2021年12月就诊于中日友好医院耳鼻咽喉头颈外科的疑似LPRD患者［研究组，135例，其中男67例，女68例，年龄18~77（43.03±13.35）岁］和健康受试者［对照组，42名，其中男20名，女22名，年龄20~23（21.26±0.67）岁］资料，评估其反流症状指数（RSI）、反流体征评分（RFS）、口咽动态pH监测（Dx-pH监测）以及RSS，1周后再次评估其RSS。对确诊的LPRD患者，给予质子泵抑制剂（PPI）治疗8周，再行RSS评估。分析比较相关结果，对RSS的信度和效度进行评估。采用SPSS 18.0软件进行统计学分析。 结果： RSS各条目之间Cronbach′s α系数为0.77。1周后再次评估上述各条目，2次评估的P值均小于0.05。RSS与Dx-pH监测结果对照显示，诊断符合率为84.44%（114/135），阳性预测值为85.71%（114/133）。确诊LPRD患者PPI治疗后的RSS明显降低［治疗前（84.79±42.50）分，治疗后（20.11±22.82）分，t=-10.54，P<0.001］。与健康受试者相比，疑似LPRD患者的症状对其生活质量的影响评分较高（t=7.15，P<0.001）。所有疑似LPRD患者和健康受试者认为RSS能较好评估其症状。 结论： RSS量表内在和外在信度良好，校标效度和反应度良好，可作为评估LPRD症状的重要参考指标之一。.
