Abstract

Purpose: Prior studies have shown that bilingual children who do not stutter (CWNS) exhibit a high number of disfluencies in both languages, increasing the risk of misidentification by speech-language pathologists as children who stutter (CWS). Conversely, there is a risk of misidentifying CWS with a relatively low incidence of disfluencies as CWNS. This study aims to explore the qualitative and quantitative distinctions in speech disfluency profiles between CWNS and CWS. The assessment covers both the dominant and nondominant language to examine the impact of language dominance on disfluency patterns.

Method: A total of 92 Lebanese bilinguals (70 CWNS and 22 CWS) from 4;06 to 7;06 (years;months) were included. Language dominance was determined based on parental assessments. Spontaneous and narrative speech samples were collected for each child in both languages and all stuttering-like disfluencies (SLD) and other disfluencies (OD) were coded.

Results: On average, CWNS showed a significantly lower percentage of total SLD, weighted SLD, SLD subtypes, and iterations compared to CWS. However, the number of disfluencies of CWNS exceeded monolingual clinical standards. Language dominance did not impact SLD and OD percentages, but some differences for SLD subtypes emerged. Binary logistic regression analyses showed that repetitions and dysrhythmic phonations are good predictors for correct CWS or CWNS classification, in contrast to OD. A combination of predictors from both languages led to better classification than using predictors from either language alone.

Conclusions: The current study shows that speech disfluency percentages in bilingual CWNS typically surpass monolingual standards and can be at par with those of CWS. However, through careful consideration of disfluency characteristics, ideally in both languages, an accurate differential diagnosis of stuttering in bilingual children can be achieved.

有口吃和没有口吃的黎巴嫩双语儿童的言语不流畅问题。
目的:先前的研究表明,不口吃的双语儿童(CWNS)在两种语言中都表现出大量不流利现象,这增加了言语病理学家将其误认为口吃儿童(CWS)的风险。相反,口吃发生率相对较低的 CWS 也有被误认为 CWNS 的风险。本研究旨在探讨 CWNS 和 CWS 在言语不流畅方面的定性和定量区别。评估范围包括主导语言和非主导语言,以研究语言主导地位对不流利模式的影响:共纳入 92 名黎巴嫩双语儿童(70 名 CWNS 和 22 名 CWS),年龄从 4;06 到 7;06(岁;月)。语言优势根据父母的评估确定。收集了每个儿童两种语言的自发言语和叙述性言语样本,并对所有口吃样不流利(SLD)和其他不流利(OD)进行了编码:平均而言,与 CWS 相比,CWNS 的总 SLD、加权 SLD、SLD 子类型和迭代的百分比明显较低。然而,CWNS 的不流畅语句数量超过了单语临床标准。语言优势对 SLD 和 OD 百分比没有影响,但在 SLD 亚型方面出现了一些差异。二元逻辑回归分析表明,与 OD 相比,重复和发音节奏失调是 CWS 或 CWNS 正确分类的良好预测因素。将两种语言的预测因子结合使用,比单独使用其中一种语言的预测因子能更好地进行分类:目前的研究表明,双语 CWNS 的语音不流畅率通常超过单语标准,并可与 CWS 的语音不流畅率相提并论。然而,通过仔细考虑不流利特征(最好是两种语言的不流利特征),可以对双语儿童口吃进行准确的鉴别诊断。

期刊介绍: Mission: AJSLP publishes peer-reviewed research and other scholarly articles on all aspects of clinical practice in speech-language pathology. The journal is an international outlet for clinical research pertaining to screening, detection, diagnosis, management, and outcomes of communication and swallowing disorders across the lifespan as well as the etiologies and characteristics of these disorders. Because of its clinical orientation, the journal disseminates research findings applicable to diverse aspects of clinical practice in speech-language pathology. AJSLP 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 speech-language pathology, including aphasia; apraxia of speech and childhood apraxia of speech; aural rehabilitation; augmentative and alternative communication; cognitive impairment; craniofacial disorders; dysarthria; fluency disorders; language disorders in children; speech sound disorders; swallowing, dysphagia, and feeding disorders; and voice disorders.
