GAD-7 anxiety screening: questions, scores and next steps
An anxiety screening is a short questionnaire, most often the GAD-7 or its 2-question version, the GAD-2. It asks how often worry and related problems have bothered you over the past 2 weeks. A score is not a diagnosis: a positive screen leads to a fuller conversation with your clinician. (USPSTF, 2023) (Johnson et al., 2019)

Who is screened
- Adults 64 and younger, including pregnant and postpartum people: the USPSTF recommends screening for anxiety disorders (grade B, 2023). It applies to adults without a diagnosed mental health condition or recognized signs of an anxiety disorder. (USPSTF, 2023)
- Adults 65 and older: the evidence is insufficient to weigh benefits and harms (I statement). That is not a recommendation against screening. (USPSTF, 2023)
- Children and teens 8 to 18: screening is recommended (grade B, 2022); for children 7 and younger the evidence is insufficient. (USPSTF, 2022)
There is little evidence on timing. A practical approach the USPSTF describes is to screen adults who have not been screened before, then use clinical judgment about risk factors, other health conditions and life events to decide whether to screen again, with ongoing attention during pregnancy and after birth. (USPSTF, 2023) Full details by age: anxiety screening and mental health screenings by age.
Why it matters: in US data from 2001 to 2002, 26.4% of men and 40.4% of women had an anxiety disorder at some point in their lives, and anxiety disorders often go unrecognized in primary care. (USPSTF, 2023) In a study of 965 patients at 15 US primary care clinics, 19.5% had at least 1 anxiety disorder, and 41% of them reported no current treatment. (Kroenke et al., 2007)
What the GAD-7 asks
The GAD-7 asks how often, over the past 2 weeks, you have been bothered by 7 problems. (Lutkiewicz et al., 2024) In summary, they cover: (Johnson et al., 2019) (Lutkiewicz et al., 2024)
- 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 it is hard to sit still
- becoming easily annoyed or irritable
- feeling afraid, as if something awful might happen
Each answer scores 0 ("not at all"), 1 ("several days"), 2 ("more than half the days") or 3 ("nearly every day"), so the total runs from 0 to 21. Higher scores mean more severe anxiety symptoms. (Lutkiewicz et al., 2024) (Johnson et al., 2019)
The GAD-2 uses the 2 core items of the GAD-7. (Kroenke et al., 2007) With the same 0 to 3 answers, it scores 0 to 6. In the original primary care study, both the GAD-7 and the GAD-2 performed well as screening tools for generalized anxiety disorder, panic disorder, social anxiety disorder and post-traumatic stress disorder. (Kroenke et al., 2007) Other tools used in the US include an anxiety subscale of the Edinburgh Postnatal Depression Scale during and after pregnancy, and the Geriatric Anxiety Scale and Geriatric Anxiety Inventory for older adults. (USPSTF, 2023)
How GAD-7 scores are read
Scores of 5, 10 and 15 are the usual cut points for mild, moderate and severe anxiety: (Lutkiewicz et al., 2024)
| GAD-7 score | Severity |
|---|---|
| 0 to 4 | Minimal (low) (Lutkiewicz et al., 2024) |
| 5 to 9 | Mild (Lutkiewicz et al., 2024) |
| 10 to 14 | Moderate (Lutkiewicz et al., 2024) |
| 15 to 21 | Severe (Lutkiewicz et al., 2024) |
- GAD-7 of 10 or more is the usual cut-off for a positive screen. (Johnson et al., 2019) In the original study, this cut point balanced sensitivity (89%) and specificity (82%): most people with generalized anxiety disorder scored 10 or more, and most people without it scored under 10. (Spitzer et al., 2006) (Johnson et al., 2019) Across the studies the USPSTF reviewed, a score of 10 or more picked out 79% of people with generalized anxiety disorder and correctly cleared 89% of people without it. (USPSTF, 2023)
- GAD-2 of 3 or more picked out 81% of people with generalized anxiety disorder and cleared 86% without it in the USPSTF review. A cut-off of 2 or more caught more (94%) but flagged more people who did not have it. (USPSTF, 2023)
- In the general population, a German national survey of 5,030 people found that about 5% scored 10 or more and 1% scored 15 or more. (Löwe et al., 2008)
Where they differ: the GAD-7 authors chose 10 as the cut point. (Spitzer et al., 2006) (Johnson et al., 2019) The USPSTF notes that lower cut-offs of 8 or 9 catch more people with generalized anxiety disorder but flag more who do not have it. (USPSTF, 2023) A 2016 meta-analysis found a cut-off of 8 acceptable and scores of 7 to 10 similar. (Plummer et al., 2016) Which cut-off a practice uses is a choice between missing fewer cases and flagging fewer people who do not have the condition.
Whatever the score, a questionnaire does not diagnose an anxiety disorder. The USPSTF says screening tools alone are insufficient for diagnosis and a positive result needs a confirmatory diagnostic assessment. (USPSTF, 2023) Your doctor decides what your result means for you.
What happens after a positive screen
The USPSTF says people who screen positive should be evaluated further for a diagnosis and, if appropriate, offered or referred for evidence-based care. (USPSTF, 2023) Your doctor decides the next step with you. This page does not give treatment advice. See also after an abnormal screening result.
What the evidence shows: 2 trials that tested anxiety screening directly found no difference in symptoms at 13 to 22 weeks, and did not report harms. The USPSTF based its grade B on adequate evidence that screening tools can accurately identify anxiety disorders and that treating anxiety disorders reduces symptoms. (USPSTF, 2023)
How it pairs with depression screening
Anxiety and depression often overlap. In one cohort study the USPSTF cites, 67% of people with a depressive disorder also had a current anxiety disorder. (USPSTF, 2023) The GAD-7 authors found that anxiety and depression symptoms often occur together but measure different things, and each affects daily functioning on its own. (Spitzer et al., 2006) For the depression form and its scores, see depression screening: what to expect, PHQ-2 and PHQ-9 scores.
Where guidelines differ on who is screened
- USPSTF: adults 64 and younger, including pregnant and postpartum people (grade B); evidence insufficient at 65 and older. (USPSTF, 2023)
- Women's Preventive Services Initiative: screen all female patients 13 and older who do not already have a diagnosed anxiety disorder, including during pregnancy and after birth, with no upper age limit stated. (USPSTF, 2023)
- American College of Obstetricians and Gynecologists: screen at least once during the perinatal period for depression and anxiety symptoms with a standardized, validated tool, and again at the comprehensive postpartum visit. (USPSTF, 2023)
The groups above are summarized as the USPSTF reports them.
Questions people ask
What questions are on the GAD-7?
It asks how often, over the past 2 weeks, you have been bothered by 7 problems: feeling nervous or on edge, not being able to stop or control worrying, worrying too much about different things, trouble relaxing, being restless, becoming easily annoyed and feeling afraid that something awful might happen. Each is answered from "not at all" to "nearly every day". (Johnson et al., 2019) (Lutkiewicz et al., 2024)
What does a GAD-7 score of 10 mean?
A score of 10 is the start of the moderate range and the usual cut-off for a positive screen. In the original study, 89% of people with generalized anxiety disorder scored 10 or more and 82% of people without it scored under 10. It is not a diagnosis: a positive screen leads to a fuller assessment. (Lutkiewicz et al., 2024) (Spitzer et al., 2006) (Johnson et al., 2019) (USPSTF, 2023)
Is a GAD-7 score a diagnosis?
No. The USPSTF says screening tools alone are not enough to diagnose an anxiety disorder, and a positive result needs a confirmatory diagnostic assessment. (USPSTF, 2023)
Who should be screened for anxiety?
The USPSTF recommends anxiety screening for adults 64 and younger, including pregnant and postpartum people (grade B, 2023), and for children and teens 8 to 18 (grade B, 2022). For adults 65 and older and children 7 and younger, it found the evidence insufficient. (USPSTF, 2023) (USPSTF, 2022)
How often should you be screened for anxiety?
The USPSTF sets no interval. A practical approach it describes is to screen adults who have not been screened before, then use risk factors, other health conditions and life events to decide whether to screen again. (USPSTF, 2023)
