Depression — PHQ-9

The PHQ-9 is a clinical screening tool for identifying depression symptoms. It assesses symptoms you experienced over the past two weeks.

⚠️ Important Notice

This questionnaire is a screening tool only and is not a diagnosis. If you are having thoughts of self-harm — seek help immediately: call 988 (Suicide & Crisis Lifeline) or go to an emergency room.

📌 Instructions

Rate how often you have been bothered by each symptom over the last 2 weeks — from "Not at all" (0) to "Nearly every day" (3).
