Single‐subject research design: recommendations for levels of evidence and quality rating
The aim of this article is to present a set of evidence levels , accompanied by 14 quality or rigor questions , to foster a critical review of published single‐subject research articles . In developing these guidelines , we review ed levels of evidence and quality /rigor criteria that are in wide use for group research design s , e.g. r and omized controlled trials , such as those developed by the Treatment Outcomes Committee of the American Academy for Cerebral Palsy and Developmental Medicine . We also review ed method ological articles on how to conduct and critically evaluate single‐subject research design s ( SSRDs ) . We then subjected the quality questions to interrater agreement testing and refined them until acceptable agreement was reached . We recommend that these guidelines be implemented by clinical research ers who plan to conduct single‐subject research or who incorporate SSRD studies into systematic review s , and by clinicians who aim to practise evidence ‐based medicine and who wish to critically review pediatric single‐subject research
