Symptoms overlap. Let's clarify the source.
9spectrum is a two-stage screening that builds a tendency profile across nine psychological dimensions. It does not diagnose. It is not a fixed quiz: based on your answers, the system changes which questions come next to home in on the result — and helps separate overlapping patterns (e.g. ADHD-style delay vs. OCD paralysis).

Two stages, one session
You move through everyday scenarios. Unlike most sites that ask everyone the same list, 9spectrum is adaptive: your answers change the question path as the system homes in on the result — deepening some areas and skipping others. About 30–45 questions, 12–20 minutes. Tap an option to continue.
Frequently asked questions
- What is 9spectrum?
- A two-stage adaptive screening that builds a tendency profile across nine psychological dimensions. It does not diagnose — it produces a map to discuss with a clinician.
- How is this different from other quizzes?
- Most sites ask everyone the same questions. On 9spectrum, your answers change which questions come next as the system homes in on the result. When two dimensions overlap, differential follow-ups open.
- Is the screening free?
- Yes. The adult screening is free and requires no account. Answers are not sent to a server; they stay on your device.
- What if symptoms overlap?
- 9spectrum screens nine dimensions together. When two are both elevated and close, differential follow-up questions open to clarify the source.
- Is the result a diagnosis?
- No. A high tendency score does not mean you have a disorder. Only a licensed clinician can diagnose.
