目的本调查的目的是确定平均话语长度（MLU）和可理解单词百分比等指标是否可以从严重言语障碍儿童的语言样本中可靠地推导出来，以及这些指标是否与测量假设相关结构的工具相关。方法15名患有严重言语障碍的学龄前儿童的语言样本（但接受性语言在正常范围内）由2名转录员独立转录。非参数统计被用来确定哪些措施，如果有的话，可以可靠地转录，并确定是否存在语言样本的措施和标准化措施的语音，语言，和cognition.ResultsReliable措施之间的相关性被提取的语言样本，包括MLU的话，平均每话语的音节数，和可理解的话的百分比。语言样本的可理解性措施与一个单词的可理解性任务。此外，语言样本MLU和来自MacArthur-Bates沟通发展量表的参与者的3个最长句子的平均长度（Fenson等人，结论语言抽样法在适当修改后，可用于部分3 ~ 5岁接受性语言正常但言语障碍严重的儿童，为他们提供可靠的表达性语言和理解性信息。
PurposeThe purposes of this investigation were to determine if measures such as mean length of utterance (MLU) and percentage of comprehensible words can be derived reliably from language samples of children with severe speech impairments and if such measures correlate with tools that measure constructs assumed to be related.MethodLanguage samples of 15 preschoolers with severe speech impairments (but receptive language within normal limits) were transcribed independently by 2 transcribers. Nonparametric statistics were used to determine which measures, if any, could be transcribed reliably and to determine if correlations existed between language sample measures and standardized measures of speech, language, and cognition.ResultsReliable measures were extracted from the majority of the language samples, including MLU in words, mean number of syllables per utterance, and percentage of comprehensible words. Language sample comprehensibility measures were correlated with a single word comprehensibility task. Also, language sample MLUs and mean length of the participants' 3 longest sentences from the MacArthur–Bates Communicative Development Inventory (Fenson et al., 2006) were correlated.ConclusionLanguage sampling, given certain modifications, may be used for some 3-to 5-year-old children with normal receptive language who have severe speech impairments to provide reliable expressive language and comprehensibility information.
