Qualitative research
This chapter offers an overview of the nature and purpose of qualitative research, its methods and processes, quality appraisal, synthesis of qualitative research, and the integration of qualitative and quantitative approaches in mixed methods research. It includes a brief description of the approaches commonly used in health and healthcare research to collect and analyse qualitative data. The authors make suggestions and provide examples to illustrate the decision-making process in choosing the method(s) of data collection when designing a qualitative project. A number of ways to ensure scientific rigour in the design, conduct, and reporting of qualitative research, with particular regard to validity and reliability, are summarized. The last two sections focus on the key strengths and limitations of qualitative research. A few practical exercises are provided at the end of this chapter to assist the reader in revising the basic steps in the design of a qualitative research project.
