Incorporating nonoverlap indices with visual analysis for quantifying intervention effectiveness in single-case experimental designs.
The field of neuropsychological rehabilitation frequently employs single case experimental designs (SCED) in research, but few if any, of the published studies use the effect sizes recommended by the American Psychological Association. Among the available methods for analysing single case designs, this paper focuses on nonoverlap methods. This paper provides examples and suggestions for integrating visual and statistical analysis, pointing out where contradictions may occur and how to be a critical consumer.
