"The mixed methods approach to conducting systematic reviews is a process whereby comprehensive syntheses of two or more types of data (e.g. quantitative and qualitative) are conducted and then aggregated into a final, combined synthesis, or qualitative and quantitative data are combined and synthesized in a single primary synthesis." (The Joanna Briggs Institute 2014 Reviewers Manual)
Mixed Methods Reviews "broaden the conceptualisation of evidence, [are] more methodologically inclusive and produce syntheses of evidence that will be accessible to and usable by a wider range of consumers.” (Sandelowski et al. (2012)
