摘　　要：目的对普通话言语测听材料中的单音节小词表进行听力正常人群的复测信度评估。方法招募听力正常青年受试者16例,运用北京市耳鼻咽喉科研究所开发的汉语言语测听智能化系统,测试每位受试者在12 dB HL下的单音节小词表识别率;时隔6至35 d后在完全相同的条件下进行第2轮测试。结果 16张普通话单音节小词表2次测试得分显著相关(r=0.748,P<0.01),在95%置信区间下的分差标准差为11.5%,临界差值为22.5%。结论正常人使用本套词表进行言语听觉能力评价研究时,当同一受试者前后2次正确识别词数差异超过5个,认为干预有效。Objective To assess the test-retest reliability of monosyllable word short lists in Mandarin Speech Test Materials （MSTMs）. Methods The sets of monosyllable word short lists were used to test the speech perception score among sixteen normal- hearing subjects utilizing the Chinese Speech Intelligent Audiometric System, which was developed by the Institute of Biomedical Engineering, Beijing Tongren Hospital, Capital Medical University. The stimulus level was fixed at 12 dB HL. The second round was carried out after an interval of 6 to 35 days. The Pearson correlation coefficient r was calculated, significance level of the difference between test and retest was examined by Student＇s t test, and critical difference（CD） for 95% corffidence interval（CI） was analyzed after ＂rationalized＂ arcsine transform with SPSS 19.0. Results Speech perception scores in tests and retests were significantly correlated with a Pearson＇s r value of 0. 748 （P〈0.01） for the short lists. Standard deviation turned out to be 11.5 %, thus the resulting value of CD was 22.5. Conclusion The intervention should be considered effective once the number of correct response presented by a subject is no less than 5 in a short list.
