What Does My GAD-7 or PHQ-9 Score Mean?
a plain-language guide to your screening results

You just filled out a questionnaire at your doctor's office. Maybe it was on a tablet in the waiting room, or maybe your doctor's assistant handed you a clipboard with a short list of questions. Now someone has told you a number, your "score," and you're not entirely sure what it means. Is 12 bad? Is 7 something to worry about? Does a high score mean you definitely have anxiety or depression?

These questionnaires are called the GAD-7 (for anxiety) and the PHQ-9 (for depression). They're two of the most widely used mental health screening tools in the world, and millions of people complete them every year. But most patients are never told what their scores actually mean, how the tools work, or what happens next. This post will walk you through all of it.

What Is the GAD-7?

The GAD-7 stands for Generalized Anxiety Disorder 7-item scale. It asks you to rate how often you've been bothered by seven specific symptoms over the past two weeks:

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

For each question, you choose one of four responses: "not at all" (0 points), "several days" (1 point), "more than half the days" (2 points), or "nearly every day" (3 points). Your total score ranges from 0 to 21.

What Your GAD-7 Score Means

Your score falls into one of four severity categories:

0 to 4: Minimal anxiety. Your anxiety symptoms are within the normal range. Everyone experiences some worry, and this score suggests it's not currently at a level that warrants clinical concern.

5 to 9: Mild anxiety. You're experiencing noticeable anxiety symptoms, but they're at the lower end of the clinical spectrum. Your provider may want to monitor this over time, especially if it's new or worsening. Treatment isn't always necessary at this level, but it depends on how much the anxiety is affecting your daily life.

10 to 14: Moderate anxiety. This is the threshold that most clinicians use as a cutoff for possible generalized anxiety disorder. A score of 10 or higher warrants further evaluation, meaning your provider should ask more detailed questions to determine whether you meet criteria for a diagnosable anxiety disorder. This doesn't automatically mean you have GAD, but it means the screening tool has flagged something worth investigating.

15 to 21: Severe anxiety. This score suggests clinically significant anxiety that may benefit from active treatment, such as psychotherapy, medication, or both. Most clinical guidelines recommend that a score in this range should prompt a conversation about treatment options.

How Accurate Is the GAD-7?

No screening tool is perfect. The GAD-7 is a screening instrument, not a diagnostic test. It's designed to identify people who might have an anxiety disorder and who need further evaluation. It cannot, by itself, diagnose you.

A Cochrane systematic review analyzed the diagnostic accuracy of the GAD-7 and found that at the standard cutoff of 10, the tool has a sensitivity of about 62% and a specificity of about 90% for detecting generalized anxiety disorder. In practical terms, this means that the GAD-7 is very good at correctly identifying people who don't have GAD (few false positives), but it misses a meaningful number of people who do have it (some false negatives).

A USPSTF evidence review reported somewhat higher sensitivity, with a pooled sensitivity of 79% and specificity of 89% at the cutoff of 10 for detecting GAD.

What does this mean for you? If you scored 10 or above, there's a good chance you have clinically significant anxiety, and further evaluation is appropriate. If you scored below 10 but still feel that anxiety is significantly affecting your life, say so. The score is a starting point for a conversation, not the final word.

The Cochrane review also found that a lower cutoff of 7 or higher maximized the balance between sensitivity (84%) and specificity (78%), suggesting that some people with clinically meaningful anxiety will score in the 7 to 9 range. If your score is in that zone and you're struggling, don't let the number dismiss your experience.

It's also important to know that the GAD-7 was originally designed to screen for generalized anxiety disorder specifically. It's less accurate at detecting other anxiety disorders like social anxiety disorder or panic disorder. A JAMA review of anxiety screening tools noted that the GAD-7 is most specific for patients presenting with generalized worries and nervousness, with fair but lower accuracy for detecting panic disorder or social anxiety disorder.

What Is the PHQ-9?

The PHQ-9 stands for Patient Health Questionnaire 9-item scale. It asks you to rate how often you've been bothered by nine specific symptoms over the past two weeks:

1. Little interest or pleasure in doing things
2. Feeling down, depressed, or hopeless
3. Trouble falling or staying asleep, or sleeping too much
4. Feeling tired or having little energy
5. Poor appetite or overeating
6. Feeling bad about yourself, or that you are a failure, or have let yourself or your family down
7. Trouble concentrating on things, such as reading the newspaper or watching television
8. Moving 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
9. Thoughts that you would be better off dead, or of hurting yourself in some way

The scoring works the same way as the GAD-7: 0 to 3 points per question, with a total range of 0 to 27.

What Your PHQ-9 Score Means

0 to 4: Minimal depression. Your depressive symptoms are within the normal range.

5 to 9: Mild depression. You have some depressive symptoms, but they're at the lower end. Your provider may recommend monitoring, lifestyle modifications, or brief supportive counseling. Active treatment with medication isn't typically recommended at this level unless symptoms are persistent or worsening.

10 to 14: Moderate depression. This is the standard cutoff for possible major depressive disorder. A PHQ-9 score of 10 or higher is considered an indication for further diagnostic evaluation and potential treatment or close monitoring. At this level, evidence-based treatment, either psychotherapy or medication, may be recommended.

15 to 19: Moderately severe depression. This score suggests the need for active treatment, including psychotherapy, medication, or a combination of both. The Department of Veterans Affairs clinical practice guideline recommends that scores of 10 to 19 be treated as uncomplicated mild to moderate MDD, with either psychotherapy or pharmacotherapy as appropriate first-line options.

20 to 27: Severe depression. This score indicates severe depressive symptoms. Clinical guidelines generally recommend medication as part of the treatment plan for severe depression, often in combination with psychotherapy. The VA guideline treats a PHQ-9 score above 20 as indicating severe, chronic, or recurrent MDD requiring more intensive management.

How Accurate Is the PHQ-9?

The PHQ-9 has been extensively validated. An individual patient data meta-analysis cited by the USPSTF (covering 47 studies and over 11,000 patients) found that at the standard cutoff of 10, the PHQ-9 has a sensitivity of 85% and a specificity of 85% for major depression when compared with a structured diagnostic interview.

This means the PHQ-9 correctly identifies about 85% of people who have major depression and correctly identifies about 85% of people who don't. That's strong performance for a screening instrument, which is why it's the most widely used depression screening tool in the world.

However, a JAMA review noted an important nuance: the PHQ-9 may overestimate depression severity when classifying patients into severity categories, compared with clinician-rated measures. This means that the severity label ("moderate," "severe") attached to your score may make things sound worse than a clinician would assess in a full evaluation. The score should inform the conversation, not replace it.

A Special Note About Question 9 on the PHQ-9

Question 9 asks about thoughts of being better off dead or hurting yourself. This question is always assessed further, regardless of your total score. Even if your overall PHQ-9 score is low, any positive response to question 9 should prompt your provider to ask follow-up questions about suicidal thoughts, plans, and safety.

If you answered this question honestly and endorsed these thoughts, that took courage. Your provider's follow-up questions aren't meant to alarm you. They're designed to understand the context and ensure you're safe. Many people have fleeting thoughts about death without any intention to act on them, but the only way your provider can know the difference is by asking.

What Happens After You Get Your Score?

A score is a starting point, not a destination. Here's what should happen next:

If your score is below the cutoff (under 10 on either scale): Your provider may simply note the result and rescreen at a future visit. If you feel that the score doesn't reflect how you're actually feeling, say so. Screening tools measure symptoms over the past two weeks, and they can miss people who are having a good two weeks in the middle of an otherwise difficult stretch.

If your score is at or above the cutoff (10 or higher): Your provider should conduct a more thorough assessment. The screening tool identifies the possibility of a disorder. A clinical evaluation, asking about the duration, severity, context, and impact of your symptoms, determines whether you actually meet diagnostic criteria and what treatment is appropriate.

Your score can be tracked over time. One of the most valuable uses of the PHQ-9 and GAD-7 is monitoring treatment response. If you start therapy or medication, your provider can readminister the questionnaire periodically to see whether your score is going down. A decrease of 5 or more points is generally considered a clinically meaningful improvement. The goal of treatment isn't necessarily to reach zero; it's to get your score into a range where symptoms are manageable and no longer significantly impairing your life.

What Your Score Doesn't Tell You

Your score doesn't tell you why you're anxious or depressed. It doesn't distinguish between depression caused by grief, medical illness, medication side effects, or a primary depressive disorder. It doesn't account for cultural differences in how symptoms are experienced or expressed. And it doesn't capture the full complexity of your mental health.

What it does is give you and your provider a common language and a shared starting point. "I scored 16 on the PHQ-9" is more specific and more actionable than "I've been feeling kind of down." It opens the door to a conversation that leads to a plan.

The Bottom Line

The GAD-7 and PHQ-9 are short, validated screening tools that help identify anxiety and depression. A score of 10 or higher on either scale is the standard threshold for further evaluation. The scores categorize symptom severity (minimal, mild, moderate, moderately severe, severe) and help guide treatment decisions. But they are screening tools, not diagnoses. They work best when paired with a clinical conversation, a provider who asks the right follow-up questions, and a patient who answers honestly.

If you've been screened and your score concerns you, bring it up. Ask what it means. Ask what happens next. The questionnaire did its job by starting the conversation. Now it's up to you and your provider to continue it.
