A useful description, not a verdict

Good to know
Questions you may have before starting
How do I choose a questionnaire?
Choose the description closest to what you want to explore. One questionnaire is enough to start.
Can a result diagnose or rule out a condition?
No. A result summarizes your answers using published scoring; it cannot diagnose or rule out a condition.
What should I know about translations?
Each questionnaire page shows the wording source and evidence for that translation.
