There is an ongoing debate regarding the nature of grounded theory, and an examination of many studies claiming to follow grounded theory indicates a wide range of approaches. In 1967 Glaser and Strauss’s ‘‘The Discovery of Grounded Theory; Strategies for Qualitative Research’’ was published and represented a breakthrough in qualitative research; it offered methodological consensus and systematic strategies for qualitative research practice. The defining characteristics of grounded theory include: simultaneous involvement in data collection and analysis, construction of analytic codes and categories from data (not from preconceived logical hypotheses), use of the constant comparative method/analysis that involves making comparisons during all steps of the analysis, developing theory during each step of data collection and analysis, memo-writing to elaborate categories, etc., theoretical sampling aiming toward theory construction (not representativeness), and conducting a literature review after performing the analysis and developing theory. When developing a theory, identification of a core category is central for the integration of other categories into a conceptual framework or theory grounded in the data. Most grounded theories are substantive theories because they address delimited problems in specific substantive areas.
