Ask whether anyone has tested a claimed match
Before you accept that one model’s stage equals another’s, look for a published study that measured the two together.
Perché funziona
Murray and O’Fallon (2020) say that Kegan’s construct-developmental work and the Loevinger lineage are judged by many, Kegan included, to measure closely related constructs, and that they know of no empirical work investigating their correlation. On this page’s reading, a claimed equivalence that has never been measured is an assumption, however finished the chart that shows it looks. Asking whether a match was tested separates a measured overlap from a plausible one.
Come farlo
- When someone says two stages are “the same,” write the claim in one sentence that names both models and both levels.
- Search for a study that scored the same people on both instruments, and read its method section, not only its abstract.
- If you find none, label the claim “plausible, untested” in your notes.
- If you find one, check whether its authors designed one of the two instruments.
Prove scientifiche
Murray and O’Fallon (2020) state that they know of no empirical work investigating the correlation between Kegan’s construct-developmental model and the Loevinger ego-development lineage, and that the neo-Piagetian theories (stage theories built on Piaget’s work) of Commons and of Fischer have not been compared thoroughly with it. This practice applies that statement as a check on claims of equivalence. (mechanistic)
The statement describes the literature as Murray and O’Fallon knew it in 2020. It is not the result of a search this page ran, and newer work may exist.

Errore comune
Treating a neat chart as a finding. A chart that lines up names is a claim about the models, and it needs its own evidence.

Altre pratiche per How the Adult Development Stage Models Compare
- Write the model’s name beside every stage you record
Each time you record a stage, write the model and its level count next to it, because the same label can sit at a different place on each scale.
- Pick the map whose resolution matches your question
Choose the model that draws the distinction your question depends on, instead of defaulting to whichever chart you saw first.
- Read a published crosswalk one level at a time
Take one level from one model, find its row in the published table, and read the spread of matches instead of a single agreed rung.
- Keep one shared stage word from carrying two meanings
When two people use the same stage name, ask which model each one means before you agree or disagree.
- Describe one situation in two maps and mark the gap
Write one real situation, read it through two developmental maps, and note exactly where the two readings disagree.
- Trace a stage chart to the paper behind it
Before you quote a level chart, find the model’s own paper and check where each level name and count comes from.
