One of the main differences between systematic and scoping reviews is found in the quality assessment stage. Quality assessment, or risk of bias, occurs when researchers assess individual studies, and the overall body of literature, for elements of bias. While necessary when undertaking a systematic review, quality assessment is not a required element of scoping reviews.
If you decide quality assessment is a necessary component to meet your review's objectives, clearly state those objectives and rationale for completing in your review. When picking a quality assessment tool, make sure the study design it evaluates matches that/those of your included studies. Several examples of quality assessment tools are listed below and grouped by study design.
Covidence uses Cochrane Risk of Bias (which is designed for rating randomized controlled trials and cannot be used for other study types) as the default tool for quality assessment of included studies. You can opt to manually customize the quality assessment template and use a different tool better suited to your review. More information about quality assessment using Covidence, including how to customize the quality assessment template, can be found below. If you decide to customize the quality assessment template, you cannot switch back to using the Cochrane Risk of Bias template.
