Depression Calculator

Depression affects millions of people worldwide, often going unnoticed until it begins to disrupt daily life. Recognizing early signs and understanding the severity of symptoms is a critical first step toward improving mental health. The Depression Self-Assessment Tool (PHQ-9) provides an easy and confidential way to evaluate your mood and determine whether you may benefit from lifestyle adjustments, counseling, or professional support.

This article explores how the PHQ-9 Depression Calculator works, its benefits, how to use it step by step, and what the results mean.

What is the PHQ-9 Depression Self-Assessment Tool?

The Patient Health Questionnaire-9 (PHQ-9) is one of the most widely used self-assessment tests for detecting and measuring the severity of depression. It consists of nine simple questions that reflect common symptoms such as:

• Loss of interest or pleasure
• Persistent sadness or hopelessness
• Fatigue and sleep changes
• Difficulty concentrating
• Changes in appetite
• Thoughts of self-harm

By answering these questions honestly, users receive a total score along with an interpretation that falls into categories ranging from Minimal Depression to Severe Depression.

⚠️ Important: This test is not a diagnosis. It is only a self-assessment tool meant for informational purposes. If symptoms are severe, professional evaluation is recommended.

2. Feeling down – Nearly every day (3 points)
3. Trouble sleeping – Several days (1 point)
4. Feeling tired – Nearly every day (3 points)
5. Poor appetite – More than half the days (2 points)
6. Feeling bad about self – Several days (1 point)
7. Trouble concentrating – Several days (1 point)
8. Moving or speaking slowly – Not at all (0 points)
