The case study: a viable approach to clinical research

The case study, although associated with several misconceptions which compromise its effective utilization, is especially appropriate for investigation of clinical nursing problems. A literature review of the application of this research approach in other practice-based disciplines was completed. Results indicate that the case study permits focusing upon the individual in an intensive, longitudinal perspective, and facilitates bridging of the research-practice gap. Internal and external validity, considered especially problematic in case studies, can be maximized by a variety of techniques.
