"The idea of using mixed methods has a long tradition in social research. But it is also recognized that mixed methods are often poorly applied. In quantitative analysis, the qualitative component, if any, is often poorly designed, integrated or reported. These guidelines are to support the design, conduct and reporting of mixed-methods in quantitative impact evaluations. That is, impact studies using a large statistical design with a qualitative component. The guidelines are based largely on the CEDIL inception paper by Jimenez et al. (2018), ‘Mixing and matching: using qualitative methods to improve quantitative impact evaluations (IEs) and systematic reviews (SRs) of development outcomes’, supplemented by a review of other relevant guidelines e.g. the CONSORT extension for development effectiveness (Bose, 2010)."
