PHQ-9
Brief self-report measure of depressive symptoms over the preceding two weeks.
A curated gateway to selected symptom screeners and personality assessment instruments available within the Digital Psychology Ecosystem. Each tool opens independently and provides its own instructions and scoring.
These instruments are screening or assessment aids, not substitutes for a clinical interview or professional evaluation. A score can indicate that further assessment may be useful; it does not by itself establish a diagnosis. Do not use an online score to label yourself or another person. If symptoms are severe, worsening, or causing significant difficulty, consider discussing them with a qualified mental-health professional.
Selected tools for common symptom domains.

This gateway does not ask you to create an account or submit answers to the main website. The individual tools are supplied as standalone browser pages. Before entering identifiable information—especially on a shared computer—review the individual tool's behaviour and avoid unnecessary personal details. For clinical use, follow your own professional, institutional, privacy and record-keeping requirements.
