Research and evidence
Some key resources and pieces of research are highlighted on these pages but they are not exhaustive and you should always carry out your own searches relating to a specific topic area, to be assured that you are accessing the most up-to-date research and evidence.
Useful starting points include SpeechBITE™, What Works and Evidence Maps from the American Speech-Language-Hearing Association (ASHA). You can access over 1,600 titles via the RCSLT journals collection.
You need to use your own critical appraisal skills when considering the quality of any piece of research, whether found on these pages or elsewhere. This will include consideration of how relevant it is to your practice and the specific people you are working with.
Please see our pages on evidence-based practice for more support on finding and critically appraising research evidence.
Systematic reviews
We have highlighted systematic reviews here because, if well-conducted, they should take into account all the relevant evidence relating to a specific research question, then appraise and synthesize this in way which can help inform decision-making. However, you still need to use your own critical appraisal skills when considering the quality of a systematic review, as with any piece of research.
Cochrane reviews
Cochrane Reviews are systematic reviews of primary research in human health care and health policy, internationally recognised as the highest standard in evidence-based health care. Search the Cochrane Database of Systematic Reviews.
