Depression & Anxiety Self-Check

PHQ-9 + GAD-7

Two clinically standard screeners to understand how you have been doing over the past two weeks. 16 items, ~3 minutes, free, no signup — results stay in your browser.

Feeling low or anxious is common — but when it lingers, it’s hard to gauge how serious it really is. PHQ-9 and GAD-7 are the two questionnaires clinicians and researchers reach for most. They don’t label you; they turn the past two weeks into a score you can read against established severity bands, helping you tell a passing dip from a signal worth attention. You’ll see separate depression and anxiety scores with plain-language interpretation right away.

What you’ll get

Separate depression & anxiety scores

PHQ-9 (depression, 0–27) and GAD-7 (anxiety, 0–21) totals, shown as two distinct signals.

Mapped to clinical bands

Your scores placed on established bands (minimal / mild / moderate / moderately severe / severe) so you know roughly where you stand.

Plain-language interpretation

Each band comes with a clear note on what it typically means and a reasonable next step.

Support when it matters

If answers touch on self-harm, the result page surfaces crisis resources prominently.

FAQ

Is this a diagnosis?

No. PHQ-9 and GAD-7 are screening tools that gauge the level of depression and anxiety symptoms. Only a qualified professional, using a fuller assessment, can make a diagnosis.

Are PHQ-9 and GAD-7 reliable?

They are among the most validated brief screeners in clinical use. PHQ-9 (Kroenke et al., 2001) and GAD-7 (Spitzer et al., 2006) are used worldwide in primary care and research.

Is my data saved?

No. All answers stay in your browser. Scoring happens locally and results travel only in the page URL — we do not see or store your answers.

What if my score is high?

A high score is a signal worth taking seriously, not a verdict. Consider talking with a doctor or mental-health professional. If you have thoughts of harming yourself, contact a crisis line right away — the result page lists options.

What is the difference between PHQ-9 and GAD-7?

PHQ-9 screens for depression (mood, interest, sleep, energy, and more), while GAD-7 screens for anxiety (worry, restlessness, irritability, tension). They often go together, which is why this check includes both.

How long does it take?

About 3 minutes for all 16 items. Your progress is saved in your browser, so you can pause and come back.

Is it really free?

Yes — completely free, no signup, no email, no paywall. PHQ-9 and GAD-7 are public-domain instruments, free to use.

Can I retake it later?

Yes. Mood and anxiety fluctuate, so scores naturally change over time. Retaking it now and then can help you track how you are doing.
