Single-case experimental designs are presented and discussed from several points of view: Historical antecedents, assessment of the dependent variable, internal and external validity and pre-experimental vs experimental single-case designs. In addition, general characteristics of experimental single-case designs are presented along with examples of the most common design types. Visual inspection as well as statistical methods for the evaluation of data are presented. It is argued that single-case experimental designs are well suited for medical research as well as clinical practice. They provide tools for testing causal hypotheses concerning the effects of interventions in the single case.
历史渊源、因变量评估、内部和外部效度以及前实验性与实验性单病例设计。此外，还介绍了实验性单病例设计的一般特征以及最常见设计类型的示例。同时还介绍了用于数据评估的视觉检查以及统计方法。本文认为，单病例实验设计非常适合医学研究和临床实践。它们为检验关于单病例干预效果的因果假设提供了工具。
