Abstract

Purpose: The purpose of this study was to investigate the diagnostic accuracy of two measures derived from spontaneous language samples, mean length of utterance in words (MLUw) and percentage of grammatical utterances (PGU), in identifying developmental language disorder (DLD) in Spanish-English bilingual children. We examined two approaches: best language and total language.

Method: The participants in this study included 74 Spanish-English bilingual children with (n = 36) and without (n = 38) DLD. Language samples were elicited through a story retell and story generation task using Frog wordless picture books in English and Spanish. Stories were transcribed and coded using the Systematic Analysis of Language Samples (Miller & Iglesias, 2020) to extract MLUw and PGU in both languages.

Results: Logistic regression analyses suggested that a model that included PGU, MLUw, and age achieved the best diagnostic accuracy in predicting group membership. Both approaches, best language and total language, had fair diagnostic accuracy.

Conclusions: In combination, PGU and MLUw seem to be useful diagnostic tools to differentiate bilingual children with and without DLD. Clinical implications and usability are discussed.

双语儿童语法和语篇长度的诊断准确性

目的：本研究旨在探讨从自发语言样本中得出的两种测量方法--平均语篇长度（MLUw）和语法语篇百分比（PGU）--在识别西班牙语-英语双语儿童发育性语言障碍（DLD）方面的诊断准确性。我们研究了两种方法：最佳语言和总语言：本研究的参与者包括 74 名患有（36 人）和未患有（38 人）发育性语言障碍的西班牙-英语双语儿童。通过使用英语和西班牙语的《青蛙》无字图画书进行故事复述和故事生成任务，获得语言样本。使用语言样本系统分析法（Miller & Iglesias, 2020 年）对故事进行转录和编码，以提取两种语言的 MLUw 和 PGU：逻辑回归分析表明，包含 PGU、MLUw 和年龄的模型在预测群体成员方面具有最佳诊断准确性。最佳语言和总语言这两种方法的诊断准确性尚可：综合来看，PGU 和 MLUw 似乎是区分患有和不患有 DLD 的双语儿童的有用诊断工具。本文对其临床意义和可用性进行了讨论。

期刊介绍： Mission: LSHSS publishes peer-reviewed research and other scholarly articles pertaining to the practice of audiology and speech-language pathology in the schools, focusing on children and adolescents. The journal is an international outlet for clinical research and is designed to promote development and analysis of approaches concerning the delivery of services to the school-aged population. LSHSS seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of audiology and speech-language pathology as practiced in schools, including aural rehabilitation; augmentative and alternative communication; childhood apraxia of speech; classroom acoustics; cognitive impairment; craniofacial disorders; fluency disorders; hearing-assistive technology; language disorders; literacy disorders including reading, writing, and spelling; motor speech disorders; speech sound disorders; swallowing, dysphagia, and feeding disorders; voice disorders.
