3~6岁儿童汉语语言发育评估量表-语法篇的信效度研究

目的 对3~6岁儿童汉语语言发育评估量表-语法篇进行信效度检验。方法 2018年12月—2019年6月期间,采用整群随机抽样的方法,抽取成都地区幼儿园1 704名2岁11个月—6岁11个月幼儿,其中男女各852名。采用3~6岁儿童汉语语言发育评估量表-语法篇对幼儿进行测评,并对量表进行信效度分析。结果 共回收有效数据1 701份。语法篇包含40个听句选图项目。内部一致性信度 Cronbach's α系数为 0.834,折半信度为0.795。项目数据整体质量检验,被试及项目Infit、Outfit MNSQ值分别为1.00、0.93及0.99、0.93。被试区分度为1.73,被试信度为0.75。40个项目的Infit MNSQ值均介于0.86和1.2 logits之间,与Rasch模型拟合好。项目难度值在-2.55至1.82 logits之间,被试个体能力值在-2.78至5.0 logits之间。结论 儿童汉语语言发育评估量表-语法篇信效度良好,可用于对中国3~6岁儿童语法发展水平进行测评,本量表能简便、有效地测量儿童语法发展情况,为中国儿童语言障碍的诊断和治疗提供参考。

Reliability and validity of grammar subscale of Children's Language Development Scale

Objective To evaluate the reliability and validity of grammar subscale of Children's Language Development Scale(CLDS). Methods A stratified cluster sampling method was adopted to randomly select 1 704 preschool children(including 852 boys and 852 girls) in Chengdu from December 2018 to June 2019. Children's language ability was evaluated with CLDS, then the reliability and validity of the grammar subscale of CLDS were tested. Results There were 1 701 completed Results in sum. The grammar scale contained 40 items of picture selection after listening to a sentence. Internal consistency reliability Cronbach's α coefficient was 0.834, and the half-fold reliability was 0.795. The infit and outfit MNSQ values of the subjects and the items were 1.00, 0.93 and 0.99, 0.93 respectively. The discrimination validity was 1.73, and the reliability of the scale was 0.75. The infit MNSQ values of 40 items were between 0.86 and 1.2 logits, which fitted well with the Rasch model. The difficulty value of items ranged from -2.55 to 1.82 logits, and the individual ability value was between -2.78 and 5.0 logits. Conclusions The grammar subscale of the CLDS has good reliability and validity. It can be applied to simply and effectively measure 3- to 6-year-old children's grammar development, so as to provide reference for diagnosing and treating speech and language disorders in Chinese children.
