Lack of formal tests to assess the various dimension of language in Persian is one of the main challenges of speech and language pathologists in Iran. The purpose of this study was to develop a Persian Syntax Comprehension Test to assess the syntax comprehension in Persian speaking children aged 4-10 years old.
the study included four phases. In the first phase, syntactic structures of Persian were extracted and then, items generation was performed. In the second phase, content validity was determined and images were designed for the items. In the third phase, two pilot studies were carried out and difficulty and discrimination indices for items were determined and in the last phase, 788 typically-developing children (436 children aged 4-6 and 352 children aged 6-10 years old) and 15 children with Developmental language disorder were recruited then, psychometric properties (construct and concurrent validity, test-retest, and split-half reliability) were evaluated. In the final step, standard score and percentile were calculated. We used Statistical Package for the Social Sciences, version 24.0 (SPSS, Inc., Chicago, IL) for the statistical analysis of the data. The significance level was (P < 0.05).
Final version of Persian syntax comprehension test contains 24 syntactic structures and 96 items. Items' Difficulty indices were between 0.33 and 0.90. There was a significant difference among the age groups for the mean total score of the Persian syntax comprehension test. In addition, a high correlation existed between total scores of this test and those of grammar understanding subtest of Test of langue development (r = 0.52, P < 0.001). The correlation of total Persian syntax comprehension test score of the two rounds of test performance and the split-half coefficient were estimated to be 0.56 and 0.85, respectively.
It seems that the Persian Syntax comprehension test has satisfactory values for the reliability and validity measures, and it can be used as a suitable instrument by researchers and clinicians.
缺乏用于评估波斯语语言各个维度的正规测试是伊朗言语和语言病理学家面临的主要挑战之一。本研究的目的是开发一种波斯语句法理解测试,以评估4至10岁说波斯语儿童的句法理解能力。
该研究包括四个阶段。在第一阶段,提取波斯语的句法结构,然后进行项目生成。在第二阶段,确定内容效度并为项目设计图像。在第三阶段,进行了两项预试验,并确定了项目的难度和区分指数。在最后阶段,招募了788名发育正常的儿童(436名4至6岁儿童和352名6至10岁儿童)和15名发育性语言障碍儿童,然后评估心理测量学特性(结构效度和同时效度、重测信度和分半信度)。在最后一步,计算标准分数和百分位数。我们使用社会科学统计软件包第24.0版(SPSS公司,伊利诺伊州芝加哥)对数据进行统计分析。显著性水平为(P < 0.05)。
波斯语句法理解测试的最终版本包含24种句法结构和96个项目。项目的难度指数在0.33至0.90之间。波斯语句法理解测试的平均总分在各年龄组之间存在显著差异。此外,该测试的总分与语言发展测试语法理解子测试的总分之间存在高度相关性(r = 0.52,P < 0.001)。两轮测试成绩的波斯语句法理解测试总分的相关性和分半系数分别估计为0.56和0.85。
波斯语句法理解测试在信度和效度测量方面似乎具有令人满意的值,并且可以被研究人员和临床医生用作合适的工具。
