Abstract

Purpose: This study investigated the relationship between three practical measures for evaluating Persian grammar expression skills, MLU, PDSS, and PEGT, in preschool children with developmental language disorder (DLD) and their typically developing (TD) peers.

Method: Secondary data were obtained by re-analyzing language samples collected in previous studies. Previously audiotaped language samples of 25 monolingual 5-7 years-old Persian children with DLD and 25 TD children were transcribed and reanalyzed to calculate MLU in words (MLU-w) and PDSS for comparison with the results of PEGT.

Results: Children with DLD had lower scores in PEGT, PDSS, and MLU-w than TD children (p < 0.001). In addition, there was a strong correlation between PDSS and MLU-w in both DLD (r = 0.91) and TD groups (r = 0.79). There was a significant correlation between PEGT and MLU (r = 0.76) and PDSS (r = 0.78) in the DLD group, while these correlations were not significant in TD group.

Conclusions: Considering the positive and significant correlation between MLU, PDSS, and PEGT in children with DLD, the use of PEGT, as a valid, reliable, and accurate test of grammar, which can be implemented quickly and easily, is suggested for clinical purposes of identification and screening of Persian children with DLD.

正常发育儿童与发育性语言障碍儿童平均话语长度(MLU)、波斯语发展性句子评分(PDSS)和波斯语摄影表达性语法测验(PEGT)的关系

目的:探讨学龄前发育性语言障碍(DLD)儿童波斯语语法表达能力的MLU、PDSS和PEGT的关系。方法:对以往研究中收集的语言样本进行再分析，获得二次资料。对25例5-7岁单语波斯语DLD患儿和25例TD患儿的录音语言样本进行转录和再分析，计算MLU in words (MLU-w)和PDSS，并与PEGT结果进行比较。结果:DLD患儿的PEGT、PDSS和MLU-w得分低于TD患儿(p结论:考虑到DLD患儿的MLU、PDSS和PEGT呈正相关且显著，建议使用PEGT作为一种有效、可靠、准确的语法测试，可以快速、容易地实施，用于临床诊断和筛查波斯儿童DLD。
