从50名学龄前儿童的语言样本被用来估计最新版的发展句子评分（DSS）系统（李和Koenigsknecht，1972年;李，1974年）的总的和组件的措施的可靠性。每个样本被分为五个，五句反应段，和DSS总分和组成部分的分数表为每个部分。估计的可靠性和标准误差的测量得到的措施涉及不同数量的响应段。本文讨论了一种方法，通过与规范性数据的比较，可以评价测量数据的标准误，以便决定样本量。应用这种方法的DSS的总成绩表明，所需的样本量分离正常与异常的语言使用者是足够大，它的使用是不切实际的，为此目的。由于缺乏关于组成测量的规范性数据，所概述的方法不能用于决定样本量，这将适用于组成测量。
Language samples taken from 50 preschool children were used to estimate the reliabilities of the total and component measures of the latest edition of the Developmental Sentence Scoring (DSS) system (Lee and Koenigsknecht, 1972; Lee, 1974). Each sample was divided into five, five-sentence response segments, and DSS total and component scores were tabulated for each segment. Estimates of reliability and standard error of measurement were obtained for the measures involved for varying numbers of response segments. A method is discussed whereby standard error of measurement data can be evaluated by comparison with normative data for the purposes of making decisions about sample size. Application of this method to the total score of DSS showed that the sample size needed for separating normal from abnormal language users was great enough that its use was impractical for this purpose. Because of the absence of normative data on the component measures, the method outlined could not be used for making decisions about sample sizes, which would be appropriate for component measures.
