Single-case experimental designs. 1: Using idiographic research

The single-case experimental design is an example of idiographic research which involves establishing causality. The reasons for using idiographic research in nursing are discussed and important differences between nomothetic and idiographic designs are highlighted in this article. Single-case experimental designs are recommended in situations where both true experimental and quasi-experimental designs are difficult or impossible to use for practical or ethical reasons. Single-case experimental designs are ideal for nursing care situations because they study individual cases, making it possible to give individualized nursing care while simultaneously studying the outcomes of specific patients.
