Mixed Methods Design (Creswell & Plano Clark)
Mixed methods combines qualitative and quantitative strands to answer questions neither can fully address alone. Integration is the hard part: designs specify sequence, priority, and mixing points.
Notable design families (overview)
- Convergent parallel: QUAN + QUAL concurrently; merge at interpretation (joint displays, side-by-side discussion).
- Explanatory sequential: QUAN → QUAL to explain mechanisms, outliers, or surprising scores.
- Exploratory sequential: QUAL → QUAN to develop measures, typologies, or survey items.
Advanced variants (embedded, transformative, multiphase) add complexity—match to aims and ethics.
Mixing strategies (integration)
Common techniques:
- Connecting: outputs of one strand feed the other (e.g., interview themes → survey items).
- Merging: compare/contrast results in discussion (watch for contradiction as insight).
- Embedding: one strand secondary within a larger project.
Document where integration happens and who decides how conflicts are resolved.
Philosophical foundations
Mixed methods can sit within pragmatism (many US textbooks), critical realism, or transformative frames. Declare how you handle incommensurability if paradigms clash—integration is easier when you articulate a coherent stance.
When to use mixed methods
Use when you need both pattern/generalization-oriented evidence and meaning/process depth—or when one strand reduces waste in the other (e.g., QUAL discovers constructs before QUAN measures them).
Grounded theory in mixed methods
GT can occupy the qualitative strand, especially in exploratory sequencing. Risks:
- QUAN pressures can force premature closure.
- Integration meetings may privilege “hard numbers.”
Mitigate by protecting iterative coding cycles and treating integration as dialogue, not automatic trump rules.
Quality criteria
Beyond mono-method rigor, assess:
- Integration clarity (not parallel play).
- Meta-inferences justified by both strands.
- Discrepancies analyzed, not hidden.
Reporting
Use diagrams of the design; specify priority, sequence, purpose of each strand, and integration points. Follow MMARS or journal-specific mixed-methods reporting guidance when required.
