Background and Aim: The aim of the present article is to describe meaning-oriented thematic analysis grounded in reflective lifeworld research and to illustrate how the thematic analysis can be integrated in the research process. The article is a methodological paper, including ontological and epistemological assumptions for lifeworld theory. Research based on lifeworld theory is directed towards lived experiences and meanings in everyday life. Research that is founded on the epistemology of the lifeworld can present existential issues important for caring and qualitative research can in particular contribute to existential knowledge needed to understand the world of the patient. Design: Theoretical paper. Results: Starting with a phenomenon of relevance for caring science, the article argues for lifeworld interviews as a data collection method that can contribute to depth and meaning, and then presents a description of how structures of meaning can be outlined through a meaning-oriented thematic analysis. The research of lived experiences in caring science demands an approach that includes a reflective attitude during the methodological considerations. This article highlights the importance of ontological and epistemological considerations when conducting a meaning-oriented thematic analysis. Conclusion: The article places meaning-oriented thematic analysis in a wider research process, considering all aspects from collection of data to the creation of meaning-oriented themes.
