Abstract

This study aimed to develop a screening test for children suspected of developmental language disorders (DLD). The study was conducted in six steps. In the first two steps, we collected 34 sentences for the sentence repetition (SR) subtest, and 40 non-words for the non-word repetition (NWR) subtest, respectively. Experts determined the content validity in the third step and 19 sentences and 19 non-words were selected. In the fourth step, we draw simple pictures for the SR subtest. In the fifth step, two pilot studies were conducted on 30 and 35 Persian-speaking children aged 4.5-5.5 years, respectively. After calculating the discrimination index of the items, we removed items with the discrimination index less than 0.3. Nineteen sentences and 14 non-words remained in this step. In the sixth step, 92 typically developing (TD) children aged 4.5-5.5 and 10 children suspected of DLD were recruited. Then, we removed some items and evaluated the construct validity and reliability of the final form of the Persian Grammar-Phonology Screening Test (PGPST).The final form of the PGPST consisted of 16 sentences, and 11 non-words were developed. The correlation between the two subtests was 0.29. Children suspected of DLD in SR (p = .001) and NWR (p = .007) performed significantly worse than the TD children. The correlation between the two administrations of the test was 0.74 and 0.71, respectively, for SR and NWR. Cronbach's alpha was also 0.84 and 0.86 for the SR and NWR subtests, respectively. The PGPST is a quick and brief screening test with acceptable validity and reliability.

波斯语语法-语音筛选测试的开发和心理测量学评估：初步研究。

本研究旨在为怀疑患有发育性语言障碍（DLD）的儿童开发一种筛查测试。研究分六个步骤进行。在前两个步骤中，我们分别收集了 34 个句子作为句子重复（SR）子测试和 40 个非词作为非词重复（NWR）子测试。在第三步中，专家确定了内容的有效性，并选出了 19 个句子和 19 个非词。第四步，我们为 SR 子测试绘制了简单的图片。第五步，分别对 30 名和 35 名 4.5-5.5 岁的波斯语儿童进行了两次试点研究。在计算了项目的辨别指数后，我们删除了辨别指数小于 0.3 的项目。在这一步中，我们保留了 19 个句子和 14 个非单词。在第六步中，我们招募了 92 名 4.5-5.5 岁的典型发育（TD）儿童和 10 名疑似 DLD 儿童。然后，我们删除了一些项目，并评估了波斯语语法-语音筛选测试（PGPST）最终形式的建构效度和信度。两个分测验之间的相关性为 0.29。在 SR（p = .001）和 NWR（p = .007）中被怀疑患有 DLD 的儿童的表现明显差于 TD 儿童。在 SR 和 NWR 中，两次测验之间的相关性分别为 0.74 和 0.71。SR 和 NWR 分测验的 Cronbach's alpha 也分别为 0.84 和 0.86。PGPST 是一种快速简短的筛查测验，其有效性和可靠性均可接受。
