Creswell, J. W., & Poth, C. N. (2018). Qualitative inquiry & research design: Choosing among five approaches (Fourth edition). SAGE.
This excerpt from Creswell and Poth's Qualitative Inquiry & Research Design outlines five qualitative research approaches: narrative research, focusing on individual life stories; phenomenological research, exploring the shared essence of experiences; grounded theory research, generating theories from data; ethnographic research, describing cultural patterns of groups; and case study research, providing in-depth analyses of specific cases. Each approach is defined, its origins explained, and key features, procedures, challenges, and emerging directions are discussed. The authors also offer guidance on choosing the most suitable approach based on research needs and provide a comparison across foundational considerations, data procedures, and reporting.
