PurposeThis study examined the psychometric properties of the Preschool Language Scales-Fifth Edition（PLS-5 English）among premier children from low-seconomic status（SES）families.MethodThe PLS-5 was administered individually to 169 3- to 4-years old children enrolled in Head Start programs.我们进行了Mokken量表分析（MSA），这是一个非参数项目反应理论分析，检查项目之间的层次结构和PLS-5听觉理解（AC）和表达性沟通（EC）scales.ResultsThe PLS-5 EC项目的测试成绩的可靠性保留了一个温和的Mokken规模与列入所有的项目。另一方面，PLS-5 AC项目形成了一个温和的Mokken规模，只有排除五个不可扩展的项目。AC和EC量表得分的潜在类信度系数均在0.90以上。几个项目，违反了不变的项目排序假设被发现为两个scales.ConclusionsMSA可以用来检查潜在的语言能力和通过一个项目的顺序响应的概率之间的关系。研究结果表明，对于低社会经济地位家庭的学龄前儿童，PLS-5 EC量表评分用于比较个体的语言表达能力是合适的;但是，研究者和语言病理学家在使用PLS-5 AC量表评分评估个体的语言接受能力时应谨慎。MSA结果的其他影响进行了进一步讨论。
PurposeThis study examined the psychometric properties of the Preschool Language Scales–Fifth Edition (PLS-5 English) among preschool children from low–socioeconomic status (SES) families.MethodThe PLS-5 was administered individually to 169 3- to 4-year-old children enrolled in Head Start programs. We carried out a Mokken scale analysis (MSA), which is a nonparametric item response theory analysis, to examine the hierarchy among items and the reliability of test scores of the PLS-5 Auditory Comprehension (AC) and Expressive Communication (EC) scales.ResultsThe PLS-5 EC items retained a moderate Mokken scale with the inclusion of all the items. On the other hand, the PLS-5 AC items formed a moderate Mokken scale only with the exclusion of five unscalable items. The latent class reliability coefficients for the AC and the EC scale scores were both above .90. Several items that violated the invariant item ordering assumption were found for both scales.ConclusionsMSA can be used to examine the relationship between the latent language ability and the probability of passing an item with ordinal responses. Results indicate that for preschool children from low-SES families, it is appropriate to use the PLS-5 EC scale scores for comparing individuals' expressive language abilities; however, researchers and speech-language pathologists should be cautious when using the PLS-5 AC scale scores to evaluate individuals' receptive language abilities. Other implications of the MSA results are further discussed.
