[Why, and How, Undertake Mixed Methods Design in Health Research: A Concrete Experience].

Summary: The use of mixed methods to address health problems generates more knowledge of reality to get a more complete analysis of the problem under investigation. This is based on the fact that answers to the questions posed are as subjective as the individuals themselves. In that way, it is necessary quantitative and qualitative data for comprehensiveness (a more realistic and comprehensive approach to the object of the study).

Objective: Reflect on this methodology through a practical example.

Synthesis: We explain, through Participatory Education Program Focused on Colorectal Cancer Surgery Patient (mixed methods research project: multistrand, sequential and mixed in each of its three phases), what is this methodology and its advantages. The second phase of the study emerges from the results of the first one, and so on. At the end of the study a metaresult, that gives meaning and response to the study in its entirety, arises.

Conclusion: Despite the challenges, mixed methods gives us a more accurate perspective of the phenomenon of study; it helps us to formulate the problem statement and the most appropriate way to study it; and finally, the scientific inferences obtained are more solidly supported.
