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.
