PHQ-9 + GAD-7 Combined Calculator

Depressive and anxiety symptoms frequently occur together, which is why many clinicians administer the PHQ-9 and GAD-7 side by side. This combined tool lets you complete both questionnaires in one place and see each score alongside a short combined summary.

PHQ-9

Over the last 2 weeks, how often have you been bothered by any of the following problems?

1Little interest or pleasure in doing things
2Feeling down, depressed, or hopeless
3Trouble falling or staying asleep, or sleeping too much
4Feeling tired or having little energy
5Poor appetite or overeating
6Feeling bad about yourself — or that you are a failure or have let yourself or your family down
7Trouble concentrating on things, such as reading the newspaper or watching television
8Moving or speaking so slowly that other people could have noticed — or the opposite, being so fidgety or restless that you have been moving around a lot more than usual
9Thoughts that you would be better off dead or of hurting yourself in some way

Question 9 asks about thoughts of self-harm or that you would be better off dead. This item helps flag a symptom that deserves immediate attention, not casual dismissal — regardless of how you answer the other items.

GAD-7

Over the last 2 weeks, how often have you been bothered by the following problems?

1Feeling nervous, anxious, or on edge
2Not being able to stop or control worrying
3Worrying too much about different things
4Trouble relaxing
5Being so restless that it is hard to sit still
6Becoming easily annoyed or irritable
7Feeling afraid as if something awful might happen

How the score is calculated

Section A is the standard nine-item PHQ-9; Section B is the standard seven-item GAD-7. Each section is scored independently using its own 0–27 or 0–21 scale — the tool does not blend the two into a single invented score, since PHQ-9 and GAD-7 measure different symptom clusters.

Reviewing depressive and anxiety symptoms together can help a clinician understand the broader picture, since the two commonly overlap and can influence each other. This combined view is a convenience for discussion with a professional — it is not a new diagnostic score.

Important limitations

  • This tool reports two independent, validated scores; it does not create a new combined diagnostic score.
  • As with each instrument individually, results are not a diagnosis and do not replace a clinical evaluation.

Frequently Asked Questions

Why complete PHQ-9 and GAD-7 together?

Depression and anxiety symptoms often co-occur, and reviewing both can give a fuller picture to discuss with a healthcare professional.

Does completing both create one combined score?

No. Each questionnaire is scored using its own validated scale. The tool shows both scores together for convenience, not a merged number.

Can I complete just one section?

Yes — you can also use the standalone PHQ-9 or GAD-7 calculators if you only need one screening.

Is this combined result a dual diagnosis?

No. Only a qualified healthcare professional can diagnose a mental health condition after a full evaluation.
