修訂學前兒童語言障礙評量表應用於大陸浙江金華地區之效度驗證

本研究旨在探討《修訂學前兒童語言障礙評量表》（簡稱PLS）簡體字版本於中國大陸地區之適用性與效度。鑒於目前大陸在學前兒童語言能力評估方面尚缺乏標準化工具，現有測驗常依賴主觀判斷或使用與語言文化不完全相符之量表，導致臨床診斷與教學介入成效有限。為改善此現況，研究者參考臺灣版本將PLS轉換為簡體字版本，並在浙江金華地區進行初步效度驗證。本研究以浙江金華地區3至5歲11個月之學前兒童為對象，包含語言發展典型發展組與語障組，透過施測簡體字版PLS，評估其在不同語言發展水準兒童間之區辨能力及其與既有語言評估工具之關聯性。研究結果顯示，簡體字版PLS可有效區分語障與非語障兒童，且得分與PPVT-R等語言測驗呈中至高度正相關。測驗亦具備良好的內部一致性與重測信度，顯示具備建構效度與應用潛力。本研究支持簡體字版PLS作為大陸學前兒童語言能力之篩查與評估工具，未來可進一步進行大樣本調查與常模建立，以提升其臨床應用價值與廣泛性。

This study aims to examine the applicability and validity of the simplified Chinese version of the Revised Preschool Language Scale (PLS) for use in Mainland China. Given the current lack of standardized tools for assessing language development in preschool children in China, existing evaluations often rely on subjective judgments or scales that are not fully adapted to the local linguistic and cultural context. To address this gap, the PLS—widely used in Taiwan—was translated into simplified Chinese and preliminarily validated in the Jinhua region of Zhejiang Province.The study recruited children aged 3 to 5 years and 11 months from Jinhua, including both typically developing children and those with language disorders. The simplified PLS was administered to evaluate its ability to discriminate between different levels of language development and to determine its correlation with existing tools such as the PPVT-R. Results indicated that the simplified PLS could effectively differentiate between children with and without language disorders. The scale demonstrated moderate to strong correlations with other established language measures and showed high internal consistency and test-retest reliability, supporting its construct validity and clinical utility.The findings suggest that the simplified PLS is a reliable and valid tool for screening and assessing preschool language ability in Mainland China. Future research may expand the sample size and establish normative data to enhance its broader clinical application.
