Frequently asked questions
Is this test free?▼
Yes, the test is fully free — every question, the scoring and the result with a dimension-by-dimension interpretation. You see your result immediately after the last answer, with no registration, e-mail or card required. An extended PDF report is available as an optional purchase, but you do not need it to see and understand your score.
How long does it take to complete?▼
It takes about 15 minutes — the test has 50 questions, each answered with a single click on a scale. There is no time limit, you can go at your own pace, and a progress bar shows how much is left. You get the most accurate results by answering spontaneously rather than deliberating over single items.
Are the results accurate?▼
The test is based on a published psychometric instrument — its source and authors are named at the top of this page. Scores are computed with the published scoring keys. Bear in mind that a self-report questionnaire captures a snapshot in time and is educational — it does not replace a clinical diagnosis by a professional.
Can I save my results?▼
Yes. Right after the test you can save the result to a free account in one click — just an e-mail; sign-in uses a 6-digit code sent to it, no password. Saved results build your psychological profile, where you can compare dimensions across different tests on one chart and revisit results any time. Without an account you still see your result, and this browser can return to it for 90 days.
