This study was undertaken to determine the relationship between syntactic structures produced on the expressive portion of the NSST and those produced in a spontaneous language sample. The NSST was administered to 12 children previously diagnosed as delayed in language. In addition, spontaneous language samples were collected by a speech clinician and by the child's mother. The children ranged in age from four years one month to five years 11 months. We found that 30 percent of those syntactic structures incorrectly produced on the NSST were correctly produced spontaneously in the language sample. Furthermore, the sample obtained by the clinician was significantly richer in terms of number of structures produced correctly than the sample collected by the mother. Overall results indicate that an item analysis of the expressive portion of the NSST does not present an accurate representation of the child's language performance and therefore cannot be interpreted beyond its stated purpose, namely that of a screening instrument.
本研究旨在确定在非标准化语言样本测试（NSST）表达部分所产生的句法结构与自发语言样本中所产生的句法结构之间的关系。对12名先前被诊断为语言发育迟缓的儿童进行了NSST测试。此外，言语治疗师和孩子的母亲收集了自发语言样本。这些孩子的年龄在4岁1个月至5岁11个月之间。我们发现，在NSST测试中错误产生的那些句法结构，有30%在语言样本中能够自发正确地产生。此外，治疗师获得的样本在正确产生的结构数量方面明显比母亲收集的样本丰富。总体结果表明，对NSST表达部分进行项目分析并不能准确反映儿童的语言表现，因此不能超出其既定目的进行解释，即作为一种筛查工具的目的。
