Multiple Case-Based Discourse Analysis
Also known as: multi-case discourse analysis, comparative discourse analysis, cross-case discourse analysis, MCDA
Multiple case-based discourse analysis is a qualitative research design that applies systematic discourse analysis within each of two or more purposively selected cases, then compares the discursive patterns, themes, and power relations across those cases. It combines the replication logic of Yin's multiple case study methodology with the text- and talk-centred analytical tools of discourse analysis traditions such as critical discourse analysis or conversation analysis, enabling researchers to build comparative, theoretically grounded accounts of how language constructs social reality across different contexts.

When to use it
Use multiple case-based discourse analysis when your research question concerns how language, texts, or talk construct social realities across more than one bounded context, and when comparison across those contexts is theoretically meaningful. It is especially suited to policy research, organizational studies, educational research, and political communication, where discourse varies systematically with institutional context. You need rich textual or verbal data from at least two clearly bounded cases; a minimum of two to four cases is typical, with four to six allowing stronger replication logic. Do not use this design when the goal is to generalize findings statistically to a population (use survey or experimental designs), when the research question does not concern language or discourse specifically (use comparative case study or thematic analysis instead), or when only a single case is available — in that case, standard discourse analysis is more appropriate.
Strengths & limitations
- Combines the contextual depth of discourse analysis with the comparative leverage of multiple case methodology, enabling pattern identification across contexts.
- The replication logic borrowed from case study design strengthens the credibility of discursive claims that extend beyond a single instance.
- Theoretically flexible: compatible with critical discourse analysis, discursive psychology, narrative analysis, and other discourse frameworks.
- Produces findings that are grounded in specific empirical contexts while remaining transferable to analogous settings through rich, transparent description.
- Particularly powerful for studying policy implementation, organizational change, or social phenomena where language is a primary mechanism of action.
- Highly time-intensive: rigorous within-case discourse analysis followed by systematic cross-case comparison requires substantial researcher time and interpretive labor.
- Findings are context-bound and not statistically generalizable; the design answers questions about meaning and construction, not frequency or distribution.
- Requires expertise in both case study methodology and at least one discourse analytic tradition — a dual competency that is demanding to develop.
- Cross-case comparisons can be complicated when cases differ substantially in context, making direct comparison of discursive categories difficult.
- The quality of the analysis depends heavily on the sufficiency and richness of the textual data; thin or highly curated institutional texts may yield limited insight.
Frequently asked
How many cases do I need for multiple case-based discourse analysis?
A minimum of two cases is required by definition, and two to four cases are typical in published work. Yin's replication logic suggests that two cases allow a first test of whether a pattern holds; three or four cases strengthen the argument substantially. Beyond six cases the analytic demands of rigorous within-case discourse analysis usually exceed what is feasible in a single study — at that scale, large-scale corpus or content analysis may be more appropriate.
Which discourse analysis framework should I use within each case?
The choice depends on your research question and epistemological commitments. Critical discourse analysis (Fairclough, van Dijk) is appropriate when the focus is on power, ideology, and social reproduction. Discursive psychology (Potter and Wetherell) suits questions about how psychological states and identities are constructed in talk. Narrative analysis fits questions about story and experience. The key requirement is that the same framework is applied consistently across all cases so that cross-case comparison is coherent.
How is this different from simply doing discourse analysis on multiple datasets?
The difference lies in design logic. Multiple case-based discourse analysis requires that each dataset be treated as a bounded case with a defined context, that within-case analysis be completed before cross-case comparison begins, and that case selection follow a replication logic (theoretical or literal). Analyzing multiple datasets without this structure produces multi-site data collection, not multiple case methodology — the comparative and theoretical architecture is what distinguishes the design.
Can I use software such as NVivo or MAXQDA for this method?
Yes, qualitative data analysis software is useful for managing large volumes of text across multiple cases, organizing codes, and facilitating systematic comparison. However, the interpretive work of discourse analysis — identifying rhetorical moves, subject positions, intertextual references, and ideological patterns — must be done by the researcher. Software manages data; it does not perform discourse analysis.
How do I assess the quality of a multiple case-based discourse analysis study?
Quality criteria draw on both discourse analysis and case study traditions. Key markers include: transparent case selection rationale; clear and consistent application of a named discourse analytic framework within each case; completed within-case analysis before cross-case synthesis; thick, evidence-rich description supporting transferability; and reflexive engagement with the researcher's own position and interpretive influence on the analysis.
