目的：本研究的目的是确定影响人工耳蜗儿童言语知觉评分的共同因素。设计：在墨尔本和悉尼的两个人工耳蜗中心收集167名植入儿童的语音感知数据。这些数据包括开放集单词和句子测试的单独试镜分数。儿童被选择的基础是他们有一个22核电极人工耳蜗植入。这些孩子的平均年龄为5岁。研究人员还收集了可能影响每个孩子言语感知得分的12个因素的信息。协方差分析用于确定显著影响语音感知得分的因素。对分析的所有因素也计算Pearson两两相关系数。结果：本研究的分析确定了占音素、单词和句子感知得分差异的51%、34%和45%的因素。植入前深度耳聋的评分每年下降1.4 - 2.4%。正常使用口语交流的孩子。得分明显高于正常使用手语或同时进行口头和手语交流的儿童。在悉尼植入的儿童平均得分高于在墨尔本植入的儿童。结论：研究结果表明，每个儿童的语音感知得分差异在很大程度上与听力学和环境因素有系统的关系。使用不同沟通方式或来自不同诊所的儿童之间存在显著差异的原因尚未确定。
Objective: The objective of this study was to identify common factors affecting speech perception scores in children with cochlear implants.Design: Speech perception data for 167 implanted children mere collected at two cochlear implant centres in Melbourne and Sydney. The data comprised audition-alone scores on open-set word and sentence tests. Children were selected on the basis that they had a Nucleus 22-electrode cochlear implant. The average age of the children was 5 yr. Information was also collected about 12 factors that may have influenced speech perception scores for each child. Analysis of covariance was used to identify factors that significantly affected speech perception scores. Pearson pairwise correlation coefficients were also calculated for all factors analyzed.Results: The analyses in this study identified factors that accounted for 51%, 34%, and 45% of the variance in phoneme, word and sentence perception scores. Scores decreased by 1.4 to 2.4% per year of profound deafness prior to implantation. Children who normally use oral communication. scored significantly higher than children normally using sign or simultaneous oral and sign communication. Children implanted in Sydney scored higher on average than children implanted in Melbourne.Conclusions: The results show that a significant part of the variation in speech perception scores is systematically related to audiological and environmental factors for each child. The reasons for significant differences between children using different communication modes or from different clinics were not identified.
