GAD-7 Scoring and Interpretation

The GAD-7 (Generalized Anxiety Disorder 7-item scale) is a 7-item self-report questionnaire that screens for generalized anxiety disorder and rates its severity over the past two weeks, scored 0 to 21. A score of 10 or above is the standard cutoff for further evaluation (sensitivity 89%, specificity 82% in the original primary care study).

The GAD-7 (Generalized Anxiety Disorder 7-item scale) is a 7-item anxiety screener used in primary care and behavioural health. Totals run 0 to 21 across four severity ranges, and 10 or above is the usual cutoff for further evaluation [1].

What is anxiety?

Anxiety is a normal human emotion that serves as an adaptive warning signal. Anxiety disorders occur when anxiety becomes excessive, persistent, hard to control, and causes significant distress or impairment, either in response to situations that don't warrant that level of concern, or through anticipatory worry about future events.

Generalized Anxiety Disorder (GAD), the anxiety disorder most widely screened for using the GAD-7, involves persistent, excessive worry about multiple topics (finances, health, work, relationships) that is difficult to control, typically accompanied by symptoms such as muscle tension, irritability, sleep disturbance, and fatigue. GAD is distinct from Social Anxiety Disorder (fear of scrutiny), Panic Disorder (fear of panic attacks), and specific phobias (fear of specific objects or situations).

The GAD-7 was developed by Spitzer, Kroenke, Williams, and Löwe in primary care [1]. How accurate it is at the usual cutoff is set out under Psychometric properties below.

What does the GAD-7 measure?

The GAD-7 measures how often a person has been bothered by core symptoms of generalized anxiety disorder over the past two weeks.

  • Covered: worry (criteria A and B) and three of the six associated symptoms: restlessness, irritability and feeling on edge.
  • Not asked: fatigue, concentration, muscle tension and sleep.

It was developed to identify probable cases of GAD and to rate severity. A later study also reported its performance for panic disorder, social anxiety disorder and PTSD [3].

How the GAD-7 was developed

The authors started from 13 candidate items: 9 matching the DSM-IV criteria for generalized anxiety disorder and 4 drawn from other anxiety scales. In a criterion-standard study in 15 US primary care clinics, they kept the 7 items that correlated most strongly with the 13-item total, and set the cutoffs against diagnoses made by mental health professionals [1].

Other measures used to identify and monitor anxiety include the HAM-A, BAI, STAI, OASIS and PSWQ.

Who is the GAD-7 for?

The GAD-7 was developed and validated in adults in primary care [1]. It has also been validated at both ends of the age range:

  • Older adults. In 438 people aged 58 to 82, a lower cutoff of ≥5 was optimal for generalized anxiety disorder (sensitivity 63%, specificity 90%) [8].
  • Adolescents. In adolescents with generalized anxiety disorder (mean age 14.8), scores of ≥11 and ≥17 best marked moderate and severe anxiety [9].

For children, use a measure built for them, such as the RCADS-25.

How do you give the GAD-7?

The GAD-7 is self-administered. Each item is answered on a 0–3 scale: 0 (not at all), 1 (several days), 2 (more than half the days), or 3 (nearly every day). In the original study there was good agreement between self-report and interviewer-administered versions [1].

  • Read aloud. It can be read to the client, in session or by phone; by phone, check the client can hold the four response options in mind for each item.
  • Who gives it. Non-clinical staff can hand it out; a clinician interprets the score.
  • Timeframe. Clarify the past-two-weeks window before the client starts.
  • Pairing. Give it with the PHQ-9 to screen for depression and anxiety together, or with the WSAS when anxiety is affecting daily functioning.
  • Languages. The Cochrane review included studies in 24 languages [4].

How do you score and interpret the GAD-7?

Score ranges

The GAD-7 is scored by summing all seven items (each 0–3), giving a total of 0 to 21: 0–4 minimal, 5–9 mild, 10–14 moderate and 15–21 severe, the cutpoints set in the original study [1] and confirmed in a later review [2]. The scorer at the top of this page shows each range with its note.

So a total of 8 is mild, 13 is moderate, and 15 or more (16, 19 or 21, say) is severe. A score of 8 is also the lower cutoff some services use (see below).

A score of 10 or above (≥10) is the standard threshold for further evaluation. Its accuracy at that cutoff is under Psychometric properties below; pooled across studies, about a third of people with GAD score below 10, so a low score does not rule it out [4].

The GAD-7 also includes a functional impairment item asking how much anxiety symptoms have made it difficult to work, care for things at home, or get along with others. This item does not contribute to the total score but provides important clinical context.

Other cutoffs and other anxiety disorders

At the ≥10 cutoff, in the original primary care sample [3]:

DisorderSensitivitySpecificity
Generalized anxiety disorder89%82%
Panic disorder74%81%
Social anxiety disorder72%80%
Post-traumatic stress disorder66%81%

A lower cutoff of ≥8 (pooled sensitivity 83%, specificity 84% for generalized anxiety disorder) is supported when missing cases is costlier than over-referral; cutoffs of 7 to 10 perform similarly [5].

Monitoring treatment response

Give the GAD-7 at baseline and at regular intervals during treatment to see whether symptoms are coming down. A change of 4 points or more on the total was the minimal clinically important difference in a study of 261 adults in a chronic depression trial [6]; its authors call for confirmation in anxiety-focused treatment.

Applying GAD-7 results in session

A high score on an item points to where to start. The VA's VISN 4 MIRECC suggests techniques matched to each GAD-7 item:

ItemTechniques to consider
1 NervousnessDiaphragmatic breathing, thought monitoring, challenging maladaptive thoughts
2 Uncontrolled worryIdentifying and challenging maladaptive thoughts, relaxation techniques
3 Worry about many thingsThought monitoring, solvable vs. unsolvable worries, identifying possible solutions
4 Trouble relaxingDiaphragmatic breathing, autogenic relaxation, guided imagery
5 RestlessnessDiaphragmatic breathing, progressive muscle relaxation, guided imagery
6 IrritabilityChallenging maladaptive thoughts, breathing techniques, identifying consequences of actions
7 Feeling afraidThought monitoring, solvable vs. unsolvable worries, challenging maladaptive thoughts

In a SOAP note, the GAD-7 score goes in the Objective section, beside the PHQ-9 when both are given.

Psychometric properties

  • Original validation. In 965 adults in primary care across 15 US clinics who also had a telephone interview with a mental health professional, the GAD-7 had good reliability, as well as criterion, construct, factorial and procedural validity. The ≥10 cut point optimized sensitivity (89%) and specificity (82%) for GAD. Increasing scores were strongly associated with functional impairment and disability days, and factor analysis confirmed GAD and depression symptoms as distinct dimensions [1].
  • Reliability. Internal consistency was excellent (Cronbach's α 0.92) and test-retest reliability good (intraclass correlation 0.83) in the original study [1].
  • Cochrane meta-analysis. Across 48 studies (19,228 participants, 27 countries, 24 languages), the GAD-7 at ≥10 had summary sensitivity of 0.64 and specificity of 0.91 for GAD, and 0.48 and 0.91 for any anxiety disorder. The area under the ROC curve was 0.86 for GAD and 0.80 for any anxiety disorder [4].

Limitations

  • Screening, not diagnosis. A positive screen warrants full clinical evaluation, including ruling out medical contributors (thyroid disease, cardiac arrhythmia) and substance-induced anxiety.
  • Lower real-world sensitivity. Pooled sensitivity at ≥10 is lower than in the derivation study, and lower again for anxiety disorders other than GAD, so a score below 10 does not rule out an anxiety disorder.
  • Heterogeneous performance. The Cochrane authors describe their summary estimates as rough averages; performance may deviate substantially in specific populations and settings.
  • Self-report. Scores reflect the respondent's own rating of the past two weeks.
  • Cut-point choice. Studies support cut-offs from 7 to 10, so the threshold should match the setting and the cost of missed cases [5].
  • Validation setting. The original validation was in US adults in primary care [1].
  • Across cultures. Evidence on cross-cultural validity is limited: a 2026 review found 9 studies (20 cultural groups), most supporting the same single-factor structure, with negligible cultural bias in the total where it was tested [7].

DSM-5-TR GAD criteria

Generalized Anxiety Disorder (GAD) is diagnosed in DSM-5-TR when the following criteria are met:

Core features (A + B):

  • A. Excessive anxiety and worry (apprehensive expectation) about a number of events or activities, occurring more days than not for at least 6 months.
  • B. The person finds it difficult to control the worry.

Associated symptoms (C): at least 3 of the following 6:

#Symptom
1Restlessness or feeling keyed up or on edge
2Being easily fatigued
3Difficulty concentrating or mind going blank
4Irritability
5Muscle tension
6Sleep disturbance (difficulty falling or staying asleep, or restless, unsatisfying sleep)

(For children, only one symptom from criterion C is required.)

Additional requirements (D–F):

  • D. The anxiety, worry, or physical symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
  • E. The disturbance is not attributable to the physiological effects of a substance (e.g., medication, drug of abuse) or a medical condition (e.g., hyperthyroidism).
  • F. The disturbance is not better explained by another mental disorder.

The GAD-7 covers part of these criteria: worry (A and B) and three of the six symptoms in C (restlessness, irritability, feeling on edge). A positive screen (≥10) is consistent with probable GAD but does not replace a structured clinical interview; medical causes (thyroid disease, cardiac arrhythmia, caffeine excess) must be excluded.

Types of anxiety disorders

In DSM-5-TR, anxiety disorders form a distinct chapter. Obsessive-compulsive disorder and trauma- and stressor-related disorders (including PTSD) are classified in separate chapters. The six principal anxiety disorders are:

DisorderCore featureICD-10-CM
Generalized Anxiety Disorder (GAD)Persistent, excessive worry about multiple topics for ≥6 months; difficult to controlF41.1
Panic DisorderRecurrent unexpected panic attacks plus persistent concern about further attacks or their consequencesF41.0
Social Anxiety Disorder (Social Phobia)Marked fear of social situations in which the person may be scrutinized by othersF40.10
Specific PhobiaMarked fear of a circumscribed object or situation (e.g., animals, heights, blood-injection-injury, enclosed spaces)F40.2xx
AgoraphobiaFear and avoidance of situations where escape might be difficult or help unavailable during a panic-like episodeF40.00
Separation Anxiety DisorderExcessive fear or anxiety concerning separation from attachment figures, beyond what is developmentally expectedF93.0

Beyond GAD, a later study reported the GAD-7's performance for panic disorder, social anxiety disorder and PTSD [3] (PTSD sits outside the anxiety chapter in DSM-5-TR). The Cochrane review [4] found lower sensitivity for any anxiety disorder (0.48 at ≥10) than for GAD alone (0.64): disorders driven by specific fears or avoidance show up less in a worry-focused scale.

GAD-7 vs GAD-2

The GAD-2 is the GAD-7's first two items. It is often a first step, with the full GAD-7 after a positive screen.

  • Original study. In the primary care sample, the GAD-7 and the GAD-2 both worked well as screens for all four anxiety disorders (area under the curve 0.80 to 0.91) [3].
  • Meta-analysis. Pooled across studies, the GAD-2 at ≥3 had sensitivity 76% and specificity 81% for generalized anxiety disorder [5].

GAD-7 vs PHQ-9 vs PCL-5

When anxiety symptoms overlap with depression or trauma presentations, GAD-7 and PHQ-9 are frequently co-administered. For combined depression, anxiety, and stress screening in a single questionnaire, the DASS-21 is a useful alternative. For a structured comparison of when to use each scale and how to interpret concurrent scores, see the PHQ-9 vs GAD-7 vs PCL-5 comparison guide.

FAQ

  • What is the GAD-7 anxiety test?

    The GAD-7 is a 7-item self-report screener for generalized anxiety disorder, scored 0 to 21. Each item asks how often a symptom has bothered the respondent over the past two weeks, on a 0 to 3 scale. It was developed by Spitzer, Kroenke, Williams and Löwe in primary care.

  • How do you score the GAD-7?

    Each of the 7 items is scored 0 (not at all), 1 (several days), 2 (more than half the days) or 3 (nearly every day). The item scores are summed for a total from 0 to 21: 0 to 4 minimal, 5 to 9 mild, 10 to 14 moderate and 15 to 21 severe anxiety.

  • What is a normal GAD-7 score?

    A GAD-7 score of 0 to 4 indicates minimal anxiety and is considered the normal range. Scores of 5 to 9 indicate mild anxiety, 10 to 14 moderate and 15 to 21 severe. A score of 10 or higher is the standard cutoff that warrants further clinical evaluation for an anxiety disorder.

  • How accurate is the GAD-7?

    In the original primary care study, a score of 10 or higher had 89% sensitivity and 82% specificity for generalized anxiety disorder. A 2025 Cochrane review pooled lower figures at the same cutoff, 64% sensitivity and 91% specificity, and an earlier meta-analysis found cutoffs from 7 to 10 performed similarly.
