Table 2 Question to consider when defining the scope

From: A proposed framework for developing quality assessment tools

What study designs will be targeted by the new tool?
Will the tool consider only risk of bias (internal validity) or will it also be concerned with assessing applicability (external validity) and possibly reporting quality?
What is the definition of quality for the tool? How is risk of bias defined? How are other components of quality defined (if included), e.g. applicability?
What type of tool structure will be adopted, e.g. simple checklist design or a domain-based approach?
How will quality items be rated within the tool?
