May I ask for specific literature detailing the most appropriate method of data analysis of Episodic Narrative Interview data by Mueller (2019)?

In the referenced article (Mueller, 2019) the author conducted a Narrative Inquiry to explore life stories and social phenomena, which presents the subjectivities inherent in naturalistic studies and requires a strict protocol in the processes of data collection and analysis (as stated by the author). The planning of the research design and the data collection/analysis follows the procedures of qualitative research methodologies, with a phenomenological basis. In addition to the books by Uwe Flick that the author mentions in the final references list, I recommend "Research Methods & Methodologies in Education", by Arthur, Waring, COE & Hedges, as well as, "Narrative methods for the human sciences" by Catherine Kohler Riessman. The later I would suggest in the context of data coding and analysis, which I imagine is more inclined towards thematic analysis, but that depends on the type of research you want to do. I hope it's useful.

Thank you for your help!

Really Mr.Pinto cleared the idea quite well.I assure the Narrative theory in this field.
