Come viene valutato questo questionario e cosa non è stato validato
Ultimo aggiornamento: September 18, 2026
Cosa possiamo affermare e cosa no
OpenJung aims to be open about both the basis and the limits of this test. You deserve to know how your results are calculated, what they can tell you, and, just as important, what they cannot.
Questa pagina raccoglie note di valutazione, limiti noti e riferimenti. Non presenta uno studio di validazione di questa implementazione, del test rapido o delle traduzioni.
Evidence and validation status
English fallback — this evidence note is available in English, Simplified Chinese, Traditional Chinese, Japanese and Korean.
Traceable source: the full test adapts the 32-item OEJTS 1.2 by Open Psychometrics. The questionnaire PDF documents that version’s items, scoring rules and license. The development page provides item-selection background, not validation of this adaptation.
Not yet published: internal consistency, test–retest reliability and factor validation for this OpenJung version, its 8-question quick test, or its translations. We do not present unsupported reliability coefficients for this implementation.
Some wording and item directions have been adapted. The quick test uses only 2 questions per dimension; scaling it to 8–40 for display does not give it the precision of the full test. Percentages describe a position on a scale, not accuracy or diagnostic probability.
Use results for reflection and communication. Near-midpoint results do not establish a fixed type. Do not use them for hiring, clinical or other high-stakes decisions.
OEJTS questionnaire items and adaptations are licensed under CC BY-NC-SA 4.0, not public domain. The MIT license covers original OpenJung code, not the questionnaire.
Current assessment version: openjung-oejts-1
