Representation of the ICF in research of speech intelligibility: A systematic review of literature describing deaf and hard-of-hearing children

The purpose of this review was to map speech intelligibility measures used for assessing d/Deaf and hard-of-hearing children onto the International Classification of Functioning, Disability and Health. This review considered perceptual speech intelligibility measures (Articulation functions b320) used to assess deaf and hard-of-hearing children aged 12 years and younger. The following electronic databases were searched: CINAHL; ERIC (ProQuest); Linguistic, Language, and Behaviour Abstracts; Scopus; Medline via PubMed; CENTRAL via Ovid; Cochrane via Ovid; and Joanna Briggs via Ovid. Data were extracted describing the article, participant, listener, study, speech intelligibility, and psychometric characteristics from the 245 included studies. Speech intelligibility was measured as articulation functions (b320) through speaking (d330) in all studies. Other Body Functions frequently measured were speech discrimination (b2304; 28%) and mental functions of language (b167; 27%). Activities and Participation factors other than speaking d330 were generally not considered. Speech intelligibility was most often measured in the context of health services (e5800; 66%). Previous research on the speech intelligibility of deaf and hard-of-hearing children has largely lacked a broader perspective of functioning. Clinicians and educators of deaf and hard-of-hearing children should consider Activities and Participation, Environmental, and Personal Factors when assessing speech intelligibility.本综述旨在将用于评估聋人（Deaf）与重听儿童的言语清晰度（speech intelligibility）测评工具，映射至《国际功能、残疾和健康分类》（International Classification of Functioning, Disability and Health）框架之中。本次综述纳入了针对12岁及以下聋人与重听儿童的感知型言语清晰度测评指标，对应构音功能（Articulation functions，b320）。本次研究检索的电子数据库包括：CINAHL数据库、ERIC（ProQuest平台）、《语言学、语言与行为文摘》（Linguistic, Language, and Behaviour Abstracts）、Scopus数据库、PubMed收录的Medline数据库、Ovid平台的CENTRAL数据库、Ovid平台的Cochrane图书馆数据库，以及Ovid平台的乔安娜·布里格斯研究中心（Joanna Briggs）数据库。研究团队从纳入的245项研究中，提取了涵盖文献基本信息、受试对象、测试听者、研究设计、言语清晰度及心理测量学特征的相关数据。所有研究均通过言语表达（speaking，d330）维度，以构音功能（b320）为指标开展言语清晰度测评。其余常被测评的身体功能包括言语识别功能（b2304，占比28%）与语言心智功能（b167，占比27%）。除言语表达（d330）外，其余活动与参与维度相关因素均未被纳入考量范围。言语清晰度测评最常开展于卫生服务场景（e5800，占比66%）。既往针对聋人与重听儿童言语清晰度的研究，大多缺乏更全面的功能视角。针对聋人与重听儿童的临床工作者与教育者，在开展言语清晰度测评时，应将活动与参与、环境因素及个人因素纳入考量范畴。
