The overarching purpose of this article is to provide an introduction to the use of rigorous single-case research designs (SCRDs) in special education and related fields. Authors first discuss basic design types and research questions that can be answered with SCRDs, examine threats to internal validity and potential ways to control for and detect common threats, and provide guidelines for selection of specific designs. Following, contemporary standards regarding rigor, measurement, description, and outcomes are presented. Then, authors discuss data analytic techniques, differentiating rigor, positive outcomes, functional relations, and magnitude of effects.
本文的主要目的是介绍严谨的单一案例研究设计（SCRD）在特殊教育和相关领域的应用。作者首先讨论了可以使用 SCRD 回答的基本设计类型和研究问题，考察了内部有效性的威胁以及控制和检测常见威胁的潜在方法，并提供了选择特定设计的指南。接下来，介绍了关于严谨性、测量、描述和结果的当代标准。然后，作者讨论了数据分析技术，区分了严谨性、积极结果、功能关系和效果大小。
