The authors assessed the quality of single-case design (SCD) studies that assess the impact of interventions on outcomes for individuals who are deaf or hard-of-hearing (DHH). More specifically, the What Works Clearinghouse (WWC) standards for SCD research were used to assess design quality and the strength of evidence of peer-reviewed studies available in the peer-reviewed, published literature. The analysis yielded four studies that met the WWC standards for design quality, of which two demonstrated moderate to strong evidence for efficacy of the studied intervention. Results of this review are discussed in light of the benefits and the challenges to applying the WWC design standards to research with DHH individuals and other diverse, low-incidence populations.
作者评估了单病例设计（SCD）研究的质量，这些研究评估了干预措施对失聪或听力障碍（DHH）个体结局的影响。更具体地说，单病例设计研究的有效证据信息中心（WWC）标准被用于评估设计质量以及同行评审、已发表文献中同行评审研究的证据强度。分析得出四项符合WWC设计质量标准的研究，其中两项显示出所研究干预措施有效性的中度至有力证据。鉴于将WWC设计标准应用于针对DHH个体及其他不同的低发病率人群的研究的益处和挑战，本文讨论了该综述的结果。
