This chapter considers computer-aided deductive critical discourse analysis with ATLAS-ti 6.2 using a case study on eco-social work research from Mauritius. Data for this case study were gathered in digital audio format from eight focus group discussions, three semi-structured interviews and various reports from secondary sources. For the analysis, a literature review using ATLAS-ti was first carried out, in order to develop a conceptual/theoretical framework related to eco-social work. Then, the gathered data were directly plugged into ATLAS-ti for a computer-aided deductive critical discourse analysis using the developed eco-social work conceptual/theoretical framework from the literature review. Using the case study as an example, this chapter (a) demonstrates the techniques, and (b) appraises the opportunities, limitations and challenges of computer-aided critical discourse analysis.
