qualitative-rigor

# Qualitative Rigor and Trustworthiness “Rigor” in qualitative research is less about replication in a narrow sense and more about **demonstrating that findings are credible, contextually meaningful, carefully documented, and reflexively produced**. Lincoln and Guba’s **trustworthiness** framework remains widely used; newer approaches add **critical, participatory, and justice-oriented** quality criteria. ## Trustworthiness criteria (Lincoln & Guba) - **Credibility:** Are findings believable from the standpoint of participants and the data? - **Transferability:** Can readers judge applicability to their settings via rich contextualization? - **Dependability:** Is the inquiry process stable and trackable enough to audit? - **Confirmability:** Are interpretations tied to evidence rather than solely researcher bias? ## Techniques mapped to criteria **Credibility** - Prolonged engagement and persistent observation. - Triangulation (data, methods, investigators—used thoughtfully). - Peer debriefing and negative case analysis. - Thick description of processes, not only outcomes. **Transferability** - Thick description of setting, actors, constraints, and local meanings. - Clear boundaries: what this study is *not* claiming. **Dependability** - Audit trail of decisions (coding changes, sampling pivots, memo evolution). - Process transparency: how data became interpretations. **Confirmability** - Audit trail + reflexive documentation. - Data extracts displayed alongside analytic claims in publications. ## Member checking (use judiciously) Member checking can support credibility but is debated in grounded theory. Document what type you used and why. See the `member-checking` skill for GT-specific cautions. ## Comparison with validity and reliability Positivist “validity/reliability” language can mis-fit constructivist paradigms. If your committee demands those terms, map them explicitly (e.g., credibility ≈ internal validity in a loose translation) **and** defend paradigm-appropriate criteria. ## Paradigm-specific quality criteria Constructivist work may emphasize **reflexivity, co-construction, and situated knowledge**. Critical and participatory approaches may add **actionability, distributive justice, and community benefit**. Pragmatist mixed-methods studies may foreground **usefulness** alongside trustworthiness. ## Reporting structure (suggested) In methods/findings: 1. State your quality framework and why it fits your paradigm. 2. List concrete techniques used (not generic promises). 3. Show evidence: excerpts, decision logs, triangulation tables. 4. Acknowledge limitations and how you searched for disconfirming evidence. ## Grounded theory note Glaserian rigor emphasizes **fit, work, relevance, modifiability** of theory relative to data. Connect trustworthiness techniques to those criteria when writing GT studies so reviewers see coherence across frameworks. ## Checklist - [ ] Quality criteria named and justified paradigmatically. - [ ] At least two credibility techniques beyond “I coded carefully.” - [ ] Dependability/confirmability supported by audit trail practices. - [ ] Transferability supported by contextual detail, not over-claiming universality. - [ ] Limitations and negative case efforts transparent. ## References (starting points) - Lincoln, Y.
