    Qualitative Data Analysis in Nursing Research: Thematic vs. Grounded Theory

    December 12, 2025

    Choosing Your Qualitative Analysis Approach

    Selecting the right qualitative analysis method is one of the most consequential decisions in nursing dissertation research. Two of the most commonly used approaches — thematic analysis and grounded theory — serve fundamentally different purposes, yet they are frequently confused or conflated by novice researchers.

    Thematic Analysis: Identifying Patterns

    Thematic analysis, as described by Braun and Clarke (2006), is a flexible method for identifying, analyzing, and reporting patterns (themes) within data. It is not tied to a specific epistemological or theoretical framework, making it adaptable to a wide range of nursing research questions.

    When to Use Thematic Analysis:

  1. You have a clear research question and want to describe patterns in the data
  2. Your study is guided by an existing theoretical framework
  3. You want to explore participants' experiences without generating new theory
  4. Your dissertation committee expects a straightforward, well-established method

    5. The Six Steps of Thematic Analysis:

  5. **Familiarization**: Immerse yourself in the data through repeated reading
  6. **Initial coding**: Generate systematic codes across the entire dataset
  7. **Theme searching**: Collate codes into potential themes
  8. **Theme reviewing**: Check themes against coded extracts and the full dataset
  9. **Theme defining**: Refine each theme's name, definition, and scope
  10. **Report writing**: Select vivid, compelling extracts for your findings chapter

    11. Grounded Theory: Building Theory

    Grounded theory, originated by Glaser and Strauss (1967) and later evolved by Charmaz (2014), aims to develop a substantive theory that is "grounded" in the data itself. This approach is inherently iterative, with data collection and analysis occurring simultaneously.

    When to Use Grounded Theory:

  11. There is no existing theory to explain the phenomenon you're studying
  12. You want to understand social processes and interactions
  13. Your goal is to develop a mid-range theory for nursing practice
  14. You're comfortable with emergent design and theoretical sampling

    15. Key Grounded Theory Procedures:

  15. **Open coding**: Line-by-line analysis to identify initial concepts
  16. **Axial coding**: Relating categories to subcategories using paradigm models
  17. **Selective coding**: Integrating categories around a core category
  18. **Constant comparison**: Continuously comparing new data with emerging categories
  19. **Theoretical saturation**: Data collection continues until no new concepts emerge
  20. **Memo writing**: Reflective notes that capture analytical decisions

    Software Tools for Qualitative Analysis

    Both approaches benefit from qualitative data analysis software:

  21. NVivo: Industry standard with robust coding and visualization features
  22. ATLAS.ti: Excellent for network mapping and theory building
  23. MAXQDA: Strong mixed-methods integration
  24. Dedoose: Cloud-based, affordable for students

    25. Ensuring Rigor in Qualitative Research

    Regardless of your chosen approach, establish rigor through:

  25. Credibility: Member checking, prolonged engagement, peer debriefing
  26. Transferability: Thick description of context and participants
  27. Dependability: Audit trail documenting all analytical decisions
  28. Confirmability: Reflexive journaling about your positionality
