The Challenge of Evidence in Disability and Rehabilitation Research and Practice: A Position Paper was developed in November, 2009, by the NCDDR's Task Force on Standards of Evidence and Methods. This task force position paper focuses on evidence for interventions in the field of disability and rehabilitation (D&R). The document's specific objectives are to clarify what is meant by the term evidence and to describe the nature of the contemporary systems used to identify and evaluate evidence in intervention research; to identify the challenges in meeting contemporary standards of evidence in the field of D&R interventions and to propose next steps for examining related issues and for taking action to promote the availability of evidence-based services and information in the field of D&R interventions.

Task Force on Systematic Review and Guidelines. (2013). Assessing the quality and applicability of systematic reviews (AQASR). Austin, TX: SEDL, Center on Knowledge Translation for Disability and Rehabilitation Research.

Abstract: The basic purpose of the AQASR document and checklist is to help busy clinicians, administrators, and researchers to ask critical questions that help to reveal the strengths and weaknesses of a systematic review, in general, and as relevant to their particular clinical question or other practical concerns. Its primary audience is clinicians, as most systematic reviews are optimized to answer the clinical questions they have.
