目的：本研究调查了多通道人工耳蜗植入4-6年后，影响语前聋儿童听觉、言语、语言和阅读结果的因素。分析控制了儿童的影响。家庭，和植入物的特点，使教育因素最有利于最大的植入benefit could identified.Method：该样本包括136 8-和9岁的儿童从美国和加拿大各地的植入5岁的Nucleus 22通道植入物。自植入以来教育干预的类型和数量构成自变量，因变量是植入后4-6年进行的一系列言语感知、言语产生、语言和阅读测试的表现，儿童、家庭和植入物本身的特征构成干预变量。一系列的多元回归分析确定的方差在每个结果占干预变量和额外的方差归因于独立variables.Results的金额：儿童和家庭的特点（主要是非语言智商）占约20%，在postimplant结果的方差。额外的24%。人工耳蜗植入后4-6年的听力、言语、语言和阅读技能与非语言智商、植入功能和使用口头交流模式密切相关。
Purpose: This study investigated factors contributing to auditory, speech, language, and reading outcomes in children with prelingual deafness after 4-6 years of multichannel cochlear implant use. The analysis controlled to the effects of child. family, and implant characteristics so that educational factors most conducive to maximum implant benefit could be identified.Method: The sample included 136 8- and 9-year-old children from across the United States and Canada who were implanted by age 5 with the Nucleus 22-channel implant. Type and amount of educational intervention since implantation constituted the independent variables, The dependent variable was performance on a battery of tests of speech perception, speech production, language, and reading administered 4-6 years postimplant, Characteristics of the child, the family, and the implant itself constituted intervening variables. A series of multiple regression analyses determined the amount of variance in each outcome accounted for by the intervening variables and the amount of additional variance attributable to independent variables.Results: Characteristics of the child and the family (primarily nonverbal IQ) accounted for approximately 20%, of the variance in postimplant Outcome. An additional 24%. was accounted for by implant characteristics and 12% by educational variables, particularly oral communication mode.Clinical implications: Auditory, speech, language, and reading skills achieved 4-6 years after cochlear implantation were most Strongly associated with nonverbal IQ, implant functioning, and use of an oral communication mode.
