Validation in grounded theory: conversation circles as a methodological strategy.

OBJECTIVE: To present the validation of a theoretical model through conversation circles in a qualitative research guided by the Grounded Theory. METHOD: Study carried out from a thesis developed in a reference hospital in the south region of Brazil. Two conversation circles happened, with participation of representatives of the "Training Prism", in the months of October and November, 2016. RESULTS: The conversation circle enabled an in depth dialogic approach of the subject of research, broadening the vision on the phenomenon and on the research. The circle also mobilized thinking as it highlighted the subjectivity of individuals, expanding the group's ability of understanding and assisting in the validation process of a theoretical model. CONCLUSION: The conversation circle emerges as a powerful strategy for the development of qualitative research in nursing, more specifically in the validation step of the Grounded Theory.
