Although the qualitative approach to research has become a dominant trend in nursing research, some commentators have argued the strengths of quantitative methods, particularly if the data are sensitively handled by investigators (1). This article argues for greater use in nursing research of a particular quantitative method: the single case experimental design. It traces the development of the methodology, describes the designs of which it consists and their associated statistical handling, and examines the relevance of the approach as a whole to nursing, particularly during the construction and testing of innovative approaches to client difficulties. The paper concludes by suggesting the potential impact of the adoption of single case methods for nursing practice and research.
尽管质性研究方法已成为护理研究中的主导趋势，但一些评论家认为定量方法也有其优势，特别是当研究者能灵活处理数据时（1）。本文主张在护理研究中更多地使用一种特定的定量方法：单病例实验设计。文章追溯了该方法的发展历程，描述了其包含的设计及其相关的统计处理方式，并探讨了该方法整体与护理的相关性，特别是在构建和测试针对客户问题的创新方法时。本文最后提出了采用单病例方法对护理实践和研究可能产生的影响。
