For decades, qualitative research methodologies have incorporated the voice of the participants in their designs and developments. Now, the increasing importance of social impact of the research worldwide has created a new scenario for qualitative researchers, in which the egalitarian dialogue could be one of the key elements. The traditional incorporation of participants into research process is not enough; we need to incorporate new components as the egalitarian dialogue in the research process to assure the social impact of the research. In this article, we first situate the concept of egalitarian dialogue and how it has been used in a great diversity of situation and areas, and second how when we use it, we can obtain both, a greater social impact, and an enrichment of the qualitative methodological research process. We based our work in a literature review in both, the main journals included in ISI Web of Science and Scopus, highlighting the journals on qualitative methodologies and revising Horizon 2020 and Seventh Framework Projects included in the CORDIS database. This literature review presents how different research groups and researchers have used egalitarian dialogue, mainly in the last decade, as an important element to reach social impact with their research.
