Depression Self-Assessment Screening Test (PHQ-9)

The Patient Health Questionnaire (PHQ-9) is a multipurpose instrument for screening, diagnosing, monitoring, and measuring the severity of depression.

How to Take the Test

The PHQ-9 is composed of 9 questions, which correlate with the nine diagnostic criteria of depression. Respondents are asked to consider each statement as it relates to their mood over the past two weeks.

Scoring and Interpretation

Each of the 9 questions is scored from 0 (not at all) to 3 (nearly every day). The scores for each question are then summed to provide a total score.

Score Interpretation:

0-4: Minimal depression
5-9: Mild depression
10-14: Moderate depression
15-19: Moderately severe depression
20-27: Severe depression

Benefits of PHQ-9

The PHQ-9 is a powerful tool for clinicians to diagnose depression and monitor treatment response. It can be used in a variety of clinical settings and can be helpful in tracking symptoms over time.

FAQs

Is the PHQ-9 diagnostic?

While the PHQ-9 corresponds with the DSM-IV diagnostic criteria, it's a screening tool and not a definitive diagnostic test. Any positive screen should be followed up with a full diagnostic assessment by a qualified clinician.

Can I diagnose myself using the PHQ-9?

No, self-assessment tools are meant for informative purposes only and are not a substitute for professional diagnosis or treatment.

What should I do if I score high on the PHQ-9?

If your score indicates moderate to severe depression, it's essential to seek guidance from a mental health professional or primary care provider.
