Choosing Your Path: Codebook or RTA?

When to use codebook / coding-reliability vs reflexive thematic analysis — with concrete domain examples and a decision walkthrough. · 12 min

The Overview introduced two traditions — codebook / coding-reliability and reflexive thematic analysis (RTA). Before you start coding, decide which one your study calls for: the choice shapes how you code, whether you measure agreement, and how you write up rigor. This lesson compares them, shows who does what, and helps you make that call up front. (Later, Comparing the Two Paths shows the same data analyzed both ways, side by side, as the payoff.)

What pulls you toward each

DimensionCodebook / coding-reliabilityReflexive TA
Research questionPrevalence, comparison, “how often / which category”Meaning, experience, “how / why”
Stance toward codesCodes can be defined in advance; meaning is stable enough to shareCodes are interpretive; the analyst is the instrument
Who analyzes & whyTwo+ coders who converge on a shared codebookTwo+ analysts who stay divergent — they discuss to deepen, never to score
Reliability claimWanted/expected (κ or α reported)Rejected as a quality measure
Main payoffTransferability + a reproducibility claimInterpretive depth + theory-building
Reporting norms (within education, HCI & social science)Venues/subfields that expect a reported reliability statistic, prevalence claims, or a reusable coding schemeVenues/subfields that expect reflexivity, an interpretive stance, and rich situated accounts
Poor fit when…The question is about contested meaningYou need prevalence counts or an auditor wants reproducibility

Concrete examples

Both traditions are used heavily across education, HCI, and the social sciences — the choice is about your study, not your discipline. The same lab, in the same field, picks differently from project to project:

Who does what, and when

The table tells you which path; this shows what each looks like in practice. The confusing part isn’t the steps — it’s the people. Both paths can use two or more researchers, so the real question is what the second person is for. In the codebook path the two coders converge — they reconcile toward one shared instrument. In RTA they stay divergent — a critical friend challenges the reading to deepen it, and the codes are never merged or scored. Same two people, opposite purpose. Pick a path and step through it:

Coder A Coder B Analyst Critical friend
Familiarize & memo Independent
Coder A Coder B

Both coders read every transcript and write their own memos and jottings — separately, so first impressions are not anchored to one another.

“I sat there for probably an hour before I asked”

Jotting: a whole hour stuck before asking — why wait? Social risk? Flag to watch.

Reflexive thematic analysis, same step: Both read + memo reflexively, separately.

Step 1 of 5

We show both paths with two people, but either can be done by one — solo RTA is common, and a lone researcher can still keep a codebook; what needs a second person is the reliability or consensus claim, not the analysis itself (Braun & Clarke, 2021).

Walk it through

The table and examples show which path fits; now run your own study through it:

The next lessons are familiarization and first-cycle coding — the mechanic is shared, but the coding stance already starts to diverge there. The paths then split fully — codebook & team coding, then reflexive coding — and meet again in Comparing the Two Paths.
