这项研究是为了确定NSST表达部分产生的句法结构与自然语言样本产生的句法结构之间的关系。对12名之前被诊断为语言发育迟缓的儿童进行了NSST测试。此外，言语临床医生和孩子的母亲收集了自发的语言样本。这些孩子的年龄从4岁1个月到5岁11个月不等。我们发现，在NSST上错误产生的句法结构中，有30%是在语言样本中自发产生的。此外，就正确产生的结构数量而言，临床医生获得的样本比母亲收集的样本要丰富得多。总体结果表明，对NSST表达部分的项目分析不能准确地反映儿童的语言表现，因此不能超越其所陈述的目的，即作为筛查工具的目的来解释。
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.
