Complex Qualitative Data Analysis: Lessons Learned From the Experiences With the Qualitative Analysis Guide of Leuven

In this article, the authors discuss critical factors to be considered when analyzing complex qualitative data. The experiences with the use of the Qualitative Analysis Guide of Leuven (QUAGOL) to analyze qualitative data were used as starting point to develop a deeper understanding of what a good qualitative analysis requires and how to deal with its challenges in less optimal research contexts. A critical analysis and discussion of the strengths and weaknesses of the guide in a broader methodological context supports its potential for use in developing strong qualitative evidence. The analysis highlighted three key strategies of undertaking the analysis of complex narrative data: the case-oriented approach, the method of constant comparison, and the use of data-generated codes. Having a good understanding of the underlying principles and how to implement them are key to conducting methodologically sound analyses.
