目的：语言样本分析被许多人认为是记录儿童口语技能的黄金标准。然而，一个限制是收集和转录语言样本所需的时间。本研究的目标是确定是否可以使用相对较短的语言samples.Method：措施产生稳定的语言样本措施，从儿童的会话和叙事语言样本后，他们被分成三个长度（1-，3-，和7分钟的样本）。将测量值进行比较，以确定短样品（1和3 min）的测量值与长样品（7 min）的测量值相比的稳定性。这些措施进行了进一步分析，以确定是否不同的成绩单削减作为年龄组（2; 8 [岁;月]5; 11与6; 0-13; 3）或抽样上下文（会话与叙述）的函数变化。生产力，词汇多样性，和话语长度的措施是最可靠的短samples.Conclusion：语言样本分析在临床协议中的有效使用的影响进行了讨论。一个框架，用于引出可靠的短样本。
Purpose: Language sample analysis is considered by many to be the gold standard for documenting children's oral language skills. One limitation, however, is the time required for collection and transcription of language samples. The goal of this study was to determine if stable language sample measures could be generated using relatively short language samples.Method: Measures were generated from children's conversational and narrative language samples after they were broken into three lengths (1-, 3-, and 7-min samples). The measures were compared to determine the stability of measures from the short samples (1 and 3 min) when compared to measures from the long sample (7 min). The measures were further analyzed to determine if differences across transcript cuts varied as a function of age group (2; 8 [ years; months]5; 11 vs. 6; 0-13; 3) or sampling context (conversation vs. narrative).Results: Overall, the language sample measures were quite consistent across the transcript cuts. Measures of productivity, lexical diversity, and utterance length were the most reliable when short samples were used.Conclusion: Implications for the efficient use of language sample analysis in clinical protocols are discussed. A framework for eliciting reliable short samples is provided.
