Do's and Don'ts in Qualitative Research: Quality Standards and Trustworthiness

Introduction​

What separates excellent qualitative research from poor qualitative research? This question is more contested than in quantitative research, where statistical conventions provide clear benchmarks. In qualitative research, quality depends on a combination of procedural rigour (following systematic steps), ethical integrity (treating participants fairly), intellectual honesty (acknowledging limitations), and communicative clarity (writing that conveys findings faithfully).

This final unit of MPC-005 brings together the practical wisdom of qualitative researchers — the do's that characterise excellent research and the don'ts (pitfalls) that undermine it. It also introduces the foundational frameworks for evaluating qualitative research quality: Lincoln and Guba's trustworthiness criteria and the broader discussion of quality standards in the field.

Do's in Qualitative Research​

The following practices are essential for producing credible, rigorous qualitative research:

✅ DO: Be Clear, Specific, and Describe the Sample​

The sample is the foundation of qualitative research. Readers must understand exactly who participated:

  • Demographics: Age, gender, education, occupation, location
  • Selection rationale: Why these participants? What was the sampling strategy?
  • Context: Social and cultural context of participants
  • Access: How were participants recruited?

Vague descriptions like "several participants were interviewed" are unacceptable. Specificity allows readers to assess transferability — whether findings might apply to similar groups in other contexts.

✅ DO: Code the Data Systematically​

Systematic coding:

  • Makes the analysis transparent and auditable
  • Reduces the risk of cherry-picking evidence that confirms expectations
  • Enables other researchers to evaluate the analytical process
  • Facilitates team research and inter-rater reliability checks

Maintaining a codebook (a documented record of code definitions and examples) is best practice.

✅ DO: Frequently Use Diagrams, Flowcharts, and Matrices​

Visual representations of data:

  • Make complex patterns accessible to readers
  • Allow comparison across multiple dimensions simultaneously
  • Are particularly useful for summarising process data and relationships
  • Complement narrative descriptions

Well-designed diagrams increase the impact of the report and demonstrate analytical sophistication.

✅ DO: Draw Conclusions Based on Current and Related Studies​

Qualitative findings do not exist in isolation — they gain meaning and credibility through connection to:

  • Prior research in the same area
  • Theoretical frameworks that explain the findings
  • Contrasting studies that challenge or contextualise the findings

Conclusions grounded in literature are more defensible and more useful to the field.

✅ DO: Develop Policies for Confirming and Validating Data​

Proactive validity strategies should be planned from the start, not added as an afterthought:

  • Member checking: Sharing interpretations with participants for verification
  • Triangulation: Using multiple data sources, methods, or investigators
  • Negative case analysis: Actively seeking data that challenges emerging interpretations
  • Audit trail: Documenting all analytical decisions
  • Peer debriefing: Discussing interpretations with a colleague who can challenge assumptions

Don'ts in Qualitative Research​

These are the critical pitfalls that undermine the quality and credibility of qualitative research:

❌ DON'T: Depend Fully on the Research Design​

No research design is perfect. Every design involves trade-offs:

  • Interview designs capture what people say, not necessarily what they do
  • Observational designs may miss participants' inner experiences
  • Documentary analysis may only capture official accounts

The researcher must acknowledge what the chosen design cannot answer, not just what it can. Overconfidence in a single design weakens credibility.

❌ DON'T: Interview Only About Successes​

Focusing exclusively on positive outcomes creates a skewed, overly optimistic picture. Failures, negative experiences, and challenges are equally important:

  • They reveal what doesn't work — crucial for programme evaluation
  • They give voice to participants who had negative experiences
  • They demonstrate intellectual honesty
  • They often contain the most analytically interesting material

In programme evaluation research (common in Indian development and health contexts), focusing only on successes can lead policymakers to scale up ineffective programmes. The truth includes failures.

❌ DON'T: Depend Completely on Questionnaires​

Questionnaires are useful but limited in qualitative research:

  • They constrain responses to researcher-predetermined categories
  • They miss body language, tone, context, and spontaneous revelations
  • Much of what is most significant emerges in conversation, not written responses
  • Observations reveal behaviour; questionnaires only capture self-reports about behaviour

The IGNOU material cautions: "much of the information can only be available through observations and interviews." Qualitative richness requires qualitative methods.

Additional Critical Don'ts (Extended)​

Beyond the three in the PDF, qualitative research literature identifies several other critical pitfalls:

Don'tWhy It Matters
Don't ignore researcher positionalityUndisclosed biases undermine credibility
Don't claim generalisability without justificationQualitative findings transfer, not generalise
Don't quote selectively to support predetermined conclusionsCherry-picking undermines trustworthiness
Don't neglect participant confidentialityEthical obligation, especially in sensitive research
Don't skip member checkingMisrepresenting participants is harmful
Don't conflate interpretation with descriptionFindings must be distinguished from analytical claims
Don't ignore deviant casesData that doesn't fit the pattern is analytically valuable

Frameworks for Evaluating Qualitative Research Quality​

The IGNOU material notes that "quality assessment of qualitative research studies still remains a challenging area." Several frameworks have been proposed:

Lincoln and Guba's Trustworthiness Framework (1985)​

The most influential framework in qualitative research quality. It proposes four trustworthiness criteria as parallels to quantitative rigour:

Qualitative CriterionQuantitative ParallelWhat It MeansHow to Achieve It
CredibilityInternal validityAre findings believable/accurate?Member checking, triangulation, prolonged engagement
TransferabilityExternal validityCan findings apply elsewhere?Thick description, purposive sampling
DependabilityReliabilityIs the process consistent?Audit trail, detailed methodology
ConfirmabilityObjectivityAre findings shaped by data, not researcher?Reflexivity, audit trail

Lincoln and Guba later added a fifth criterion: Authenticity — whether the research benefits participants and represents multiple perspectives fairly.

Blaxter's Criteria (1996)​

Mildred Blaxter proposed that quality in qualitative research includes:

  • Theoretical appropriateness: Methods matched to research questions
  • Analytic adequacy: Depth and completeness of analysis
  • Interpretive sensitivity: Respect for participants' perspectives
  • Communicative adequacy: Clarity and accessibility of reporting
  • Reflexive awareness: Researcher awareness of their own influence

COREQ (Consolidated Criteria for Reporting Qualitative Research, 2007)​

A 32-item checklist developed for health research, covering:

  • Research team and reflexivity
  • Study design
  • Analysis and findings

COREQ has been widely adopted in medical and psychological journals as a standard for reporting quality.

Quality Assessment in Indian Research Contexts​

Quality in qualitative research has specific implications in the Indian research context:

  1. Language and translation: Studies conducted in regional languages must document translation processes carefully — interpretation can be lost or distorted in translation
  2. Power differentials: Researchers from elite urban institutions studying rural or marginalised communities must be reflexive about power dynamics that shape the research relationship
  3. Community benefit: Research on marginalised communities should include explicit attention to how findings will benefit those communities — aligned with ICMR ethical guidelines
  4. Cultural sensitivity: Research on sensitive topics (caste discrimination, domestic violence, mental illness stigma) requires additional ethical care and validity strategies
  5. Institutional ethics: ICMR and university ethics boards increasingly require detailed qualitative methodology and validation strategies in ethics applications

✅ Self-Assessment Questions​

Level 1 — Recall​

  1. List three do's and three don'ts from the IGNOU framework for qualitative research.
  2. What are Lincoln and Guba's four trustworthiness criteria? What quantitative concept does each parallel?

Level 2 — Understanding​

  1. Why is it a problem to "interview only about successes"? What is lost if failures and negative experiences are excluded from qualitative research?
  2. Explain the difference between credibility and transferability in qualitative research. How is each established?

Level 3 — Application & Analysis​

  1. A researcher has conducted a qualitative study on the experiences of women who have left abusive marriages in Delhi. Evaluate the following aspects of their research from a quality standpoint: (a) They interviewed 15 women — 14 from upper-middle-class backgrounds. (b) They coded data but kept no codebook. (c) They reported only positive stories of recovery and empowerment. (d) They did not do member checking because the topic was too sensitive. For each, identify the quality concern and suggest how it could be addressed.

Summary​

Quality in qualitative research is achieved through conscious adherence to best practices (the do's) and vigilant avoidance of common pitfalls (the don'ts). The IGNOU framework emphasises clear sample description, systematic coding, visual data displays, literature-grounded conclusions, and proactive validity strategies — while warning against over-reliance on research designs, selective reporting of successes, and dependence on questionnaires. Lincoln and Guba's trustworthiness framework — credibility, transferability, dependability, confirmability — provides the foundational vocabulary for assessing qualitative research quality. This final unit completes MPC-005's journey through research methods, leaving students equipped with the tools to conduct, evaluate, and report rigorous, ethical, and socially valuable qualitative research.
