The single case experimental design: a quantitative method for everyday use.
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.
