目的：在人工耳蜗植入者中验证开放式言语评估系统（Mandarin speech perceptiontest ，MSP）双音节材料的表间等价性。方法选择50例人工耳蜗植入者（年龄30．44±12．71岁），在声场中测试其在安静环境下开放式言语评估系统中10张音位平衡双音节词表的言语识别率，采用RM －ANOVA测试分析其表间等价性。结果MSP 10张双音节词表测得的平均言语识别率依次为59．26％±23．49％、64．31％±23．35％、59．97％±23．07％、62．40％±25．16％、62．75％±24．47％、62．29％±23．55％、62．85％±24．60％、61．35％±23．73％、61．82％±25．28％、58．83％±25．13％，各词表之间的平均言语识别率差异无统计学意义，表明10张词表之间有良好的等价性[ F（9，490）＝0．255，P＝0．986＞0．05]。结论开放式言语评估系统中的10张双音节词表具有良好的表间等价性，可应用于临床及科研中汉语人工耳蜗植入者的言语评估。

英文摘要：

Objective To evaluate the inter -list equivalency of the disyllabic materials for Mandarin speech perception test （MSP） by measuring the speech recognition score of patients with cochlear implant （CI） .Methods According to Latin -square design ,disyllabic recognition scores （quiet background） were measured for each of the 10 phonemically balanced lists in 50 Mandarin-speaking CI users（aged 30 .44 ± 12 .71 years）in sound field .RM -ANOVA was administered to confirm the list equivalency .Results The sentence recognition scores were 59 .26% ± 23 .49% ,64 .31% ± 23 .35% ,59 .97% ± 23 .07% ,62 .40% ± 25 .16% ,62 .75% ± 24 .47% ,62 .29% ± 23 .55% , 62 .85% ± 24 .60% ,61 .35% ± 23 .73% ,61 .82% ± 25 .28% ,58 .83% ± 25 .13% ,respectively for the 10 lists .There was no significance difference in sentence recognition scores across the 10 disyllabic lists [F（9 ,490）=0 .255 ,P=0 .986〉0 .05] .Conclusion The good inter -list equivalency of the disyllabic materials for Mandarin speech perception test （MSP） has been proved to be useful for assessing speech recognition performance of Mandarin -speaking CI users .
