目的
对不同语言测量的诊断准确性的研究主要集中在英语上。本研究探讨了敏感性和特异性的一系列措施的语言知识和语言处理识别的主要语言障碍（PLI）在讲法语的儿童。由于缺乏有据可查的法语语言措施，很难准确查明受影响的儿童，因此阻碍了这方面的研究。
方法
14名单语法语儿童与确认，临床确定PLI（M = 61.4个月的年龄，SD = 7.2个月）的一系列语言和语言处理措施的性能进行了比较，与78名儿童确认典型的语言发展（M年龄= 58.9个月，SD = 5.7）的性能。这些评估包括接受性词汇，接受性语法，自发语言，叙事生产，非词重复，句子模仿，以下方向，快速自动化命名，和数字跨度。在3个临界点确定灵敏度、特异性和似然比：（a）-1 SD，（B）-1.28 SD和（B）-2 SD低于平均值。使用受试者操作特征曲线来确定每种测量的最准确截止值。
结果
PLI和典型的语言发展组之间的显着差异被发现为大多数的语言措施，中到大的效果大小。这些措施的敏感性和特异性不同，以及哪个临界点提供了最准确的决定。在大多数情况下，理想的截止点在平均值和-1 SD之间。模仿句子和遵循指示似乎是最准确的措施。
结论
这项研究提供的证据表明，语言和语言处理的标准化措施提供准确的识别PLI在法国。结果是惊人的相似，以前的结果为英语，这表明，尽管语言之间的结构差异，PLI在两种语言涉及广义的语言延迟跨语言领域，这可以确定在一个类似的方式使用现有的标准化措施。
PURPOSE
Research on the diagnostic accuracy of different language measures has focused primarily on English. This study examined the sensitivity and specificity of a range of measures of language knowledge and language processing for the identification of primary language impairment (PLI) in French-speaking children. Because of the lack of well-documented language measures in French, it is difficult to accurately identify affected children, and thus research in this area is impeded.
METHOD
The performance of 14 monolingual French-speaking children with confirmed, clinically identified PLI (M = 61.4 months of age, SD = 7.2 months) on a range of language and language processing measures was compared with the performance of 78 children with confirmed typical language development (M age = 58.9 months, SD = 5.7). These included evaluations of receptive vocabulary, receptive grammar, spontaneous language, narrative production, nonword repetition, sentence imitation, following directions, rapid automatized naming, and digit span. Sensitivity, specificity, and likelihood ratios were determined at 3 cutoff points: (a) -1 SD, (b) -1.28 SD, and (b) -2 SD below mean values. Receiver operator characteristic curves were used to identify the most accurate cutoff for each measure.
RESULTS
Significant differences between the PLI and typical language development groups were found for the majority of the language measures, with moderate to large effect sizes. The measures differed in their sensitivity and specificity, as well as in which cutoff point provided the most accurate decision. Ideal cutoff points were in most cases between the mean and -1 SD. Sentence imitation and following directions appeared to be the most accurate measures.
CONCLUSIONS
This study provides evidence that standardized measures of language and language processing provide accurate identification of PLI in French. The results are strikingly similar to previous results for English, suggesting that in spite of structural differences between the languages, PLI in both languages involves a generalized language delay across linguistic domains, which can be identified in a similar way using existing standardized measures.
