Frequently Asked Questions
What is the Depression Screener test?
The Depression Screener is based on the PHQ-9 (Patient Health Questionnaire-9), a widely used clinical screening tool developed by Pfizer. It measures depressive symptoms including low mood, loss of interest, sleep changes, and concentration problems. This is a screening tool, not a diagnosis.
How accurate is this depression test?
The PHQ-9 has strong clinical validity with sensitivity and specificity around 85-90%. However, only a mental health professional can diagnose depression. Use this result as a conversation starter with a doctor or therapist.
What's the difference between sadness and depression?
Sadness is a normal response to loss or disappointment lasting days or weeks. Depression is persistent low mood lasting 2+ weeks that interferes with daily functioning, work, and relationships. Depression involves hopelessness and worthlessness, not just sadness.
Can depression be treated?
Yes, effectively. Evidence-based treatments include psychotherapy (CBT, IPT), medication (antidepressants), lifestyle changes (exercise, sleep, social connection), and often a combination. Most people improve significantly with proper treatment.
Is depression a sign of weakness?
No. Depression is a medical condition like diabetes or heart disease — not a character flaw. It's treatable, and seeking help is a sign of strength, not weakness.
