[Mixed methods studies in the health sciences. A critical map].

Mixed methods studies (MMS) play an increasingly important role in the health sciences. Its potential lies in the acquisition of causal conditions and in the intersubjective understanding of diverse and new phenomena. The holistic and multi-perspective analysis strategy of MMS also allows a subject-oriented and an evidence-based approach to clinical practice. The article reviews the use of MMS in the health sciences on the basis of various reviews, and it highlights current methodological developments and research gaps.
