About the PHQ-9 Depression Screener
The Patient Health Questionnaire-9 (PHQ-9) is a widely used, clinically validated instrument designed to screen for and measure the severity of depression. Originally developed by Drs. Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke, and colleagues, it incorporates DSM-IV depression diagnostic criteria with other leading major depressive symptoms into a brief self-report tool.
Score Interpretation
- 0–4 (Minimal): Symptoms are not clinically significant. Focus on maintaining healthy habits.
- 5–9 (Mild): Symptoms are present but may be manageable with self-care, lifestyle adjustments, and mindfulness.
- 10–14 (Moderate): Symptoms may be interfering with daily life. Cognitive Behavioral Therapy (CBT) or counseling is often recommended.
- 15–19 (Moderately Severe): Symptoms are causing significant distress. A formal evaluation by a mental health professional is highly recommended.
- 20–27 (Severe): Symptoms are severely impacting daily functioning. Immediate professional support and potential medical intervention are advised.
