Developmental Sentence Scoring (DSS) was developed as a numerical measurement and a clinical method based on the morphosyntactic acquisition in the English language. The aim of this study was to develop a new numerical tool similar to DSS to assess the morphosyntactic abilities in Persian-speaking children. In this cross-sectional and comparative study, the language samples of 115 typically developing Persian-speaking children aged 30 - 65 months were audio recorded during the free play and picture description sessions. The Persian Developmental Sentence Score (PDSS) and the Mean Length of Utterance (MLU) were calculated. Pearson correlation and one - way Analysis of variance (ANOVA) were used for data analysis. The correlation between PDSS and MLU in morphemes (convergent validity) was significant with a correlation coefficient of 0.97 (p< 0.001). The value Cronbach's Alpha (α= 0.79) in the grammatical categories and the split-half coefficient (0.86) indicated acceptable internal consistency reliability. The PDSS could be used as a reliable numerical measurement to estimate the syntactic development in Persian-speaking children.
发展性句子评分（DSS）是一种基于英语形态句法习得的数值测量方法和临床方法。本研究的目的是开发一种类似于DSS的新数值工具，以评估说波斯语儿童的形态句法能力。在这项横断面比较研究中，对115名年龄在30至65个月之间、发育正常的说波斯语儿童在自由玩耍和图片描述环节进行了语言样本的音频录制。计算了波斯语发展性句子评分（PDSS）和平均语句长度（MLU）。采用Pearson相关性分析和单因素方差分析（ANOVA）进行数据分析。PDSS与语素中的MLU之间的相关性（聚合效度）显著，相关系数为0.97（p<0.001）。语法类别的Cronbach's Alpha值（α=0.79）和分半系数（0.86）表明内部一致性可靠性可接受。PDSS可作为一种可靠的数值测量方法，用于评估说波斯语儿童的句法发展。
