This chapter focuses on the benefits of using a mixed methods approach when researching Corporate Social Responsibility (CSR). The author’s research investigates a sample of debtors’ and debt collectors’ perceptions of responsibility and blame for consumer debt by using a number of research methods: qualitative in-depth interviews, focus groups, and quantitative online surveys. Using mixed methods for the research approach was advantageous for a number of reasons: utilizing a number of methods ensures that the researcher can enjoy the qualities of several different research methods; further, using different methods enables the researcher to recognize and assess the validity and reliability of a single research method when comparing it against another. The author will outline to the reader the strengths, shortcomings, representativeness and validity of the aforementioned research methods, along with the sampling strategy used by the author as a CSR researcher. This chapter is aimed at early career researchers in the field of CSR to provide them with an overview of using a mixed methods approach in CSR research and, specifically, a more detailed insight into the methods of interviewing, focus groups and surveys, using the author’s research as a case study.
