中文摘要：

目的：评估汉语普通话言语测听材料（Mandarinspeechtestmaterials，MSTMs）中的等价语句测听材料在听力正常成人中的复测信度，以进一步完善该材料的标准化设计。方法随机抽取40例18～30岁听力言语正常的受试者，采用MSTMs中的等价语句测听材料（共15张测试表），根据预实验结果测试受试者相对好耳在9dBHL时的言语识别率，间隔14～28天后在完全相同的条件下复测言语识别率，对两轮测试结果进行配对t检验，并计算临界差值。结果除表6外，其余14张MSTMs语句测听材料两轮言语识别率得分差异均无统计学意义；取95％置信区间的临界差值为18．93％，对应关键词数10个。结论本实验测得MSTMs语句测听材料复测信度好；使用该语句测听材料进行言语听觉能力评估时，若同一受试者前后两次识别率差异超过18．93％、对应关键词数超过10个，则认为干预有效。

英文摘要：

Objective To evaluate the test -retest reliability of sentence materials, and to standardize Man_darin Speech Test Materials （MSTMs）. Methods Forty normal-hearing subjects aged from 18 to 30 years old were recruited in this study. The sentence materials were tested at 9 dB HL to these subjects according to the prepare ex_periment. The retest was carried out in the same condition after an interval of 14～28 days. The difference between test and retest score was examined by t-test, and the critical difference （CD） was analyzed with 95% confidence in_terval （CI）. ResuIts There was no significant difference between the test and retest scores about speech perception performance. The critical difference was 18. 93% at 95% confidence interval, and the number of the corresponding key words was 10. ConcIusion The results showed that sentence materials of MSTMs have good test-retest relia_bility except list 6. The interventions could be considered effective just when the difference of the same subject＇s score exceed 18. 93%, that means 10 key words are necessary to improve that the intervention is effective.
