Purpose The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were identified as having a developmental language disorder or specific language impairment. From these articles, we identified the tests and measures used to identify participants and classify them as healthy or impaired. We then consulted the test manuals and the literature to find information on sensitivity and specificity of the test and the evidence-based cut score that maximized identification accuracy. Results Of the 90 articles examined, 38 (42%) were found to reflect validated diagnostic methods, and 51 (58%) did not. Conclusion Our results illustrate that validated methods are used less than half of the time even by those who should have a high level of expertise and despite calls for increasing scientific rigor in research practices.
目的 本研究的目的是调查发育性语言障碍领域的研究人员在多大程度上使用经过验证的方法来诊断他们的研究参与者。方法 我们查阅了2015年至2019年发表的90篇研究文章，这些文章纳入了来自美国的英语使用者，他们被确定患有发育性语言障碍或特定语言障碍。从这些文章中，我们确定了用于识别参与者并将他们分类为健康或受损的测试和测量方法。然后，我们查阅测试手册和文献，以获取有关测试的敏感性和特异性以及使识别准确性最大化的循证临界分数的信息。结果 在查阅的90篇文章中，发现38篇（42%）反映了经过验证的诊断方法，51篇（58%）没有。结论 我们的结果表明，即使是那些应该具有高水平专业知识的人，并且尽管有人呼吁在研究实践中提高科学严谨性，但经过验证的方法使用时间不到一半。
