The GAD-7 is a seven-question screening tool used to measure how severe your anxiety symptoms are. Developed in 2006 by Robert Spitzer and colleagues, it was originally designed to help primary care doctors recognize generalized anxiety disorder (GAD) in patients who might otherwise go undiagnosed. Today it’s one of the most widely used anxiety questionnaires in healthcare, recommended by the U.S. Preventive Services Task Force as part of routine anxiety screening for adults.
What the Seven Questions Ask
The GAD-7 asks you to rate how often you’ve been bothered by seven specific problems over the past two weeks. Each item targets a different facet of anxiety:
- Feeling nervous, anxious, or on edge
- Not being able to stop or control worrying
- Worrying too much about different things
- Trouble relaxing
- Being so restless that it’s hard to sit still
- Becoming easily annoyed or irritable
- Feeling afraid, as if something awful might happen
For each item, 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). The whole thing takes about two minutes to complete, and you can score it yourself by adding up your points.
How Scores Are Interpreted
Your total score falls somewhere between 0 and 21. Clinicians group those totals into four severity levels:
- 0 to 4: Minimal or no anxiety
- 5 to 9: Mild anxiety
- 10 to 14: Moderate anxiety
- 15 to 21: Severe anxiety
A score of 10 or higher is the standard threshold that signals a possible anxiety disorder worth investigating further. That doesn’t mean a score of 10 equals a diagnosis. It means your symptoms are significant enough that a clinician should follow up with a more detailed evaluation. Think of it as a flag, not a verdict.
How Accurate Is It?
At the cutoff of 10 or higher, the GAD-7 has a sensitivity of about 64% and a specificity of 91% for detecting generalized anxiety disorder. In practical terms, the tool is very good at correctly identifying people who don’t have an anxiety disorder (few false alarms), but it misses a meaningful number of people who do have one. Roughly one in three people with GAD will score below 10 and not be flagged.
When it comes to detecting other anxiety disorders like social anxiety or panic disorder, accuracy drops further, with sensitivity falling to around 48%. The questionnaire was built around the specific symptoms of generalized anxiety, so it naturally picks up that condition more reliably than others. A high score can still reflect panic disorder, social anxiety, or post-traumatic stress, but a low score doesn’t rule those out.
The GAD-2: A Shorter Version
The GAD-2 uses just the first two items from the full questionnaire (feeling nervous and not being able to stop worrying) with a cutoff score of 3 or higher. It’s often used as a quick first step in settings where time is limited, like an annual physical. If you score 3 or above on the GAD-2, your provider may then give you the full GAD-7 for a more detailed picture.
Interestingly, large-scale analyses have found no statistically significant difference in diagnostic accuracy between the two versions. The GAD-2 picks up generalized anxiety disorder with about 68% sensitivity and 86% specificity, numbers that are comparable to the full seven-item version. The main advantage of the longer form is that it gives a more granular severity score and captures a wider range of symptoms, which is useful for tracking changes over time.
How It’s Used in Practice
You’re most likely to encounter the GAD-7 in a primary care office, a therapist’s intake paperwork, or an online mental health platform. Because it asks about the past two weeks, it provides a snapshot of your current anxiety level rather than a long-term pattern. That makes it useful not just for initial screening but for monitoring whether treatment is working. A provider might have you fill it out at each visit to see if your score trends downward as therapy or medication takes effect. A drop of several points over a few weeks generally indicates meaningful improvement.
The USPSTF now recommends routine anxiety screening for all adults, including pregnant and postpartum individuals, and the GAD-7 and GAD-2 are the most commonly studied tools for that purpose. This means you may be handed this questionnaire even if anxiety isn’t the reason you came in.
What the GAD-7 Can’t Tell You
The GAD-7 is a screener, not a diagnostic test. It tells you how many anxiety symptoms you’re experiencing and how often, but it can’t distinguish between anxiety caused by a mental health condition and anxiety driven by something else entirely, like thyroid problems, medication side effects, or a stressful life event that will pass on its own. A high score is a starting point for conversation, not a conclusion.
It also measures a narrow slice of anxiety. Symptoms like avoidance of specific situations, intrusive thoughts, or flashbacks won’t show up in your score. If you’re dealing with a type of anxiety that doesn’t revolve around persistent worry and restlessness, the GAD-7 may underestimate what you’re going through. Providers who suspect a different anxiety disorder will typically use additional tools tailored to those conditions.
