Abstract:
Objeetive 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 chi-square test (P ＜ 0.05),the difference was statistically significant.Conclusion RSI Simplified Chinese version has good rcliability 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.
