ABSTRACT
The preceding chapters should have provided the reader with some critical acumen in evaluating single-case research, which this chapter further develops. The first part of this chapter considers and illustrates the merits of formal quality rating scales that have been designed to evaluate published reports. Given the problems of applying these scales to clinical practice, the chapter outlines an approach to appraisal of an individual case study. It then describes Elliott’s hermeneutic single-case efficacy design, which encourages the thoughtful analysis of multiple sources of evidence. This approach is particularly useful to students when preparing case studies.
