The PHQ-2 is a brief, two-question screening tool used to identify possible depression. It asks about the frequency of depressed mood and anhedonia (loss of interest or pleasure) over the past two weeks. Each item is scored from 0 (not at all) to 3 (nearly every day), giving a total score from 0 to 6.
This calculator helps you quickly compute your PHQ-2 score and interpret the result. A score of 3 or higher suggests that further evaluation by a qualified professional may be warranted. It is not a diagnosis, but a screening aid that can guide conversations with your healthcare provider.
Use the dropdowns below to select how often you have experienced each symptom. The tool will calculate your total score, show the standard interpretation, and provide a brief breakdown of your responses.

How the PHQ-2 Works
The PHQ-2 is a validated screening instrument derived from the full Patient Health Questionnaire (PHQ-9). It focuses on the two core symptoms of depression: anhedonia and depressed mood. Each item is scored on a 0–3 scale, and the total score ranges from 0 to 6.
Research has shown that a cutoff score of 3 or higher has a sensitivity of about 83% and a specificity of about 92% for major depression, making it a useful first-step screening tool. However, it is not a diagnostic instrument. A positive screen should be followed by a more comprehensive assessment, such as the PHQ-9 or a clinical interview.
Worked Examples
Example 1: You select “Several days” for question 1 (1 point) and “Not at all” for question 2 (0 points). Total = 1. This is below the cutoff, suggesting that major depression is unlikely.
Example 2: You select “More than half the days” for question 1 (2 points) and “Nearly every day” for question 2 (3 points). Total = 5. This is well above the cutoff, indicating a high likelihood of depression and a strong recommendation to seek professional evaluation.
Tips & Best Practices
- Answer honestly based on your actual experience, not how you think you should feel.
- Consider the entire two-week period, not just your mood today.
- If your score is 3 or higher, do not panic. Many people experience depressive symptoms, and effective treatments are available.
- Use this tool as a conversation starter with your doctor or a mental health professional.
Limitations
The PHQ-2 is a screening tool, not a diagnostic test. It can miss some cases of depression (false negatives) and can also produce false positives, especially in people with anxiety or other conditions. It does not assess severity, duration, or functional impairment. A comprehensive evaluation by a qualified professional is essential for an accurate diagnosis.
Frequently Asked Questions
What does a score of 3 mean?
A score of 3 or higher is considered a positive screen for possible depression. It does not mean you have depression, but it does suggest that further evaluation is warranted.
Can I use this for someone else?
Yes, but the person should answer the questions themselves. The PHQ-2 is designed for self-report, and proxy responses may be less accurate.
Is the PHQ-2 available in other languages?
Yes, the PHQ-2 has been translated into many languages and is widely used internationally. The original English version is available from PHQ Screeners.
What should I do if my score is high?
Reach out to a healthcare provider, a mental health professional, or a trusted support person. If you are in crisis, contact a crisis line or emergency services immediately.
