As the need for research continues, scientists, epidemiologists, public health practitioners, and physicians are always trying to identify new ways to study and understand the impact of different issues on various populations. Grounded Theory is a qualitative approach that is often overlooked, it allows the researcher to conceptualize participants’ perceptions beyond themes. In addition, the grounded theory approach has the capability to measure categories and subcategories based on properties and dimensions. There are eight common techniques that can be used to explore a qualitative phenomenon. These include narrative research, phenomenology, ethnography, case study, conversation analysis, discourse analysis, oral history, and grounded theory. Qualitative approaches are often confused with one another because of their overarching properties. However, they are methodologically distinctive, and data interpretation varies across inquiries. The similarities and differences are explained in detail throughout this paper. The overall purpose of this paper is to summarize the existing qualitative approaches, explain practical strategies, and discuss the importance of using grounded theory.
