背景资料：对儿童语言问题的标准和术语缺乏一致意见，影响了获得服务的机会，也阻碍了研究和实践。我们报告的第二阶段的研究使用在线德尔菲方法来解决这些问题。在第一阶段，我们专注于语言障碍的标准。在这里，我们考虑术语。研究方法：德尔菲法是一个反复的过程，在这个过程中，一个专家小组对一组初始的陈述进行评级，然后他们有机会查看其他小组成员的匿名评级。在此基础上，他们可以修改自己的观点，也可以为自己的立场提出理由。然后根据小组的反馈对陈述进行修改，并再次由小组进行评级和评论。在这项研究中，第二轮的反馈被用来准备最后一套陈述的叙述形式。该小组包括代表各种职业和国籍的57名个人。结果：在两轮评级中，我们对21个陈述中的19个达成了至少78%的一致。这些声明被分解为12项声明，以达成此处报告的最终共识。术语“语言障碍”是指在日常生活中导致功能障碍并与预后不良相关的困难。当语言障碍与已知的生物医学病因无关时，“发育性语言障碍”（DLD）一词被认可使用。还一致认为，（a）存在风险因素（神经生物学或环境）并不排除DLD的诊断，（B）DLD可与其他神经发育障碍（如ADHD）同时发生，（c）DLD不需要言语和非言语能力之间的不匹配。结论：这个德尔菲练习强调了语言障碍术语分歧的原因，并提出了标准的定义和命名。
Background: Lack of agreement about criteria and terminology for children's language problems affects access to services as well as hindering research and practice. We report the second phase of a study using an online Delphi method to address these issues. In the first phase, we focused on criteria for language disorder. Here we consider terminology. Methods: The Delphi method is an iterative process in which an initial set of statements is rated by a panel of experts, who then have the opportunity to view anonymised ratings from other panel members. On this basis they can either revise their views or make a case for their position. The statements are then revised based on panel feedback, and again rated by and commented on by the panel. In this study, feedback from a second round was used to prepare a final set of statements in narrative form. The panel included 57 individuals representing a range of professions and nationalities. Results: We achieved at least 78% agreement for 19 of 21 statements within two rounds of ratings. These were collapsed into 12 statements for the final consensus reported here. The term 'Language Disorder' is recommended to refer to a profile of difficulties that causes functional impairment in everyday life and is associated with poor prognosis. The term, 'Developmental Language Disorder' (DLD) was endorsed for use when the language disorder was not associated with a known biomedical aetiology. It was also agreed that (a) presence of risk factors (neurobiological or environmental) does not preclude a diagnosis of DLD, (b) DLD can co-occur with other neurodevelopmental disorders (e.g. ADHD) and (c) DLD does not require a mismatch between verbal and nonverbal ability. Conclusions: This Delphi exercise highlights reasons for disagreements about terminology for language disorders and proposes standard definitions and nomenclature.
