The purpose of this article is to present the epistemological, ontological, and methodological deliberations that emerged during the development of the doctoral research titled "Configuration of Affective Practices and Knowledge in Single-Parent Families in the City of Bogotá, Colombia." These deliberations arise from the decolonial perspective adopted in the study. They address, on one hand, the questioning of the exclusion of emotions in discourses anchored in this perspective, and on the other hand, the subalternization of a single population group, and the fragmentation of being maintained by some decolonial understandings deriving from it. These deliberations drive a methodological proposal to decolonize social research. This proposal connects some epistemological interpretations of decoloniality with certain ontological and methodological notions offered by complexity, resulting in four guiding axes for research action. These axes lead to the implementation of three approaches: reflexive groups, selfdiscovery of affective experiences in family daily life, and the spiral of emotional time. [ABSTRACT FROM AUTHOR]
