Qualitative Research Guide

Qualitative Research Guide

A skill for designing and conducting rigorous qualitative research. Covers major qualitative traditions, data collection methods, coding and analysis techniques, and quality criteria for trustworthy qualitative findings.

Major Qualitative Traditions

Choosing an Approach

Grounded Theory Process

Data Collection (interviews, observations)
       |
       v
Open Coding: Line-by-line coding of raw data
       |
       v
Axial Coding: Grouping codes into categories,
              identifying relationships
       |
       v
Selective Coding: Identifying the core category
                  that integrates all others
       |
       v
Theoretical Saturation: Stop when new data
                        no longer generates new codes
       |
       v
Substantive Theory: A grounded explanation of the phenomenon

Interview Design

Semi-Structured Interview Protocol

Codebook Structure

codebook:
  - code: "ADAPT"
    definition: "Participant describes adapting their behavior in response to a challenge"
    inclusion_criteria: "Explicit mention of changing approach or strategy"
    exclusion_criteria: "Passive acceptance without behavioral change"
    example_quote: "I started doing things differently after that..."
    theme: "Resilience Strategies"

  - code: "BARR"
    definition: "Participant identifies a barrier or obstacle"
    inclusion_criteria: "Something that prevented or hindered progress"
    exclusion_criteria: "General complaints without specific barrier"
    example_quote: "The main thing holding me back was..."
    theme: "Challenges"

Quality Criteria

Trustworthiness (Lincoln & Guba, 1985)

Inter-Coder Reliability

For team-based coding, calculate Cohen's kappa or percent agreement on a subset of data (at least 10-20% of the corpus). Aim for kappa > 0.70 before independent coding proceeds.
