How this instrument works
The GAD-7 asks how often, over the past two weeks, seven anxiety symptoms have been bothersome: feeling nervous or on edge, being unable to stop or control worrying, worrying too much about different things, trouble relaxing, restlessness, irritability, and feeling afraid something awful might happen. Each is rated from 0 (not at all) to 3 (nearly every day), and the seven ratings sum to a total from 0 to 21.
Robert Spitzer, Kurt Kroenke, Janet Williams, and Bernd Löwe developed and validated the scale, publishing it in the Archives of Internal Medicine in 2006. Their validation study found that a cutoff of 10 or above balanced sensitivity and specificity well for identifying probable generalized anxiety disorder, correctly flagging about 89 out of 100 people who had the condition while correctly clearing about 82 out of 100 who didn't. Four bands are now standard: 0-4 minimal, 5-9 mild, 10-14 moderate, and 15-21 severe anxiety.
A high score is not the same as a diagnosis. The GAD-7 screens for the likelihood of generalized anxiety disorder based on symptom frequency alone; it doesn't rule out other conditions that share overlapping symptoms, like depression or panic disorder, and it can't weigh duration, functional impact, or context the way a clinical interview can. Treat a score at or above 10 as a reasonably strong signal worth a real conversation with a clinician, not as a self-administered verdict.
- Rate each of the seven items — feeling nervous, uncontrollable worry, worrying too much, trouble relaxing, restlessness, irritability, and fear something awful will happen — from Not at all (0) to Nearly every day (3).
- Base every rating on the past two weeks specifically, not your anxiety in general.
- Read the total, the sum of all seven items, from 0 to 21.
- Check which band the total falls in — minimal, mild, moderate, or severe — and treat 10 or above as a cue to discuss it with a clinician.
Worked example — three totals across the bands
Ratings of 2, 2, 3, 2, 1, 2, and 1 across the seven items sum to 2+2+3+2+1+2+1 = 13, landing in the moderate band (10-14) and above the ≥10 threshold the 2006 validation study found best balanced sensitivity and specificity for probable generalized anxiety disorder.
A mostly quiet two weeks — six items at 0 and two at 1 — sums to 0+1+0+1+0+0+0 = 2, well within the minimal band (0-4). At the other end, nearly every day on all seven items gives 3×7 = 21, the maximum score and squarely in the severe band (15-21).
Questions
What GAD-7 score suggests probable generalized anxiety disorder?
A total of 10 or above. The 2006 validation study by Spitzer and colleagues found this cutoff correctly identified about 89% of people who had generalized anxiety disorder (sensitivity) while correctly clearing about 82% of those who didn't (specificity) — a solid balance, though not perfect, which is why a positive screen is meant to prompt a clinical conversation rather than stand as a diagnosis on its own.
What do the GAD-7 severity bands mean?
0-4 is read as minimal anxiety, 5-9 as mild, 10-14 as moderate, and 15-21 as severe. These bands help communicate roughly how much anxiety symptoms are showing up day to day, but they're a guide for conversation and monitoring over time, not fixed cutoffs that determine treatment by themselves.
Does a high GAD-7 score mean I have an anxiety disorder?
Not by itself. The GAD-7 screens for the likelihood of generalized anxiety disorder based on how often seven symptoms occurred over two weeks; it doesn't establish duration beyond that window, rule out overlapping conditions like depression or panic disorder, or weigh how much the symptoms affect daily functioning. A high score is a strong reason to have that fuller conversation with a clinician, not a diagnosis you can hand yourself.
Why does the GAD-7 only ask about the past two weeks?
Because that window is short enough to capture a current, meaningful pattern rather than someone's memory of anxiety in general, while still being long enough to smooth out a single bad day. It mirrors the timeframe used in related instruments like the PHQ-9 for depression, making the two easier to use and compare together in practice.
Can the GAD-7 be used to track anxiety over time?
Yes — that's one of its most common uses. Because it's short and quick to repeat, clinicians often re-administer it every few weeks during treatment to see whether the total is trending down, which offers a rough, consistent way to gauge whether an intervention is helping, alongside the person's own account of how they're doing.
What should I do if my GAD-7 score is moderate or severe?
Treat it as a reason to talk with a doctor or mental health professional soon, who can explore the symptoms further, consider other explanations, and discuss options like therapy or medication if appropriate. The score itself doesn't prescribe a treatment — it's a structured way of describing how present these seven symptoms have been, which a clinician then interprets in context.
