Formula
GAD-7 Total Score = Sum of 7 items (each rated 0-3)
The GAD-7 sums responses to seven questions about anxiety symptoms experienced over the past two weeks. Each item is scored 0 (not at all) to 3 (nearly every day), giving a total range of 0 to 21. Scores of 5, 10, and 15 represent cutoffs for mild, moderate, and severe anxiety.
Worked Examples
Example 1: Moderate Anxiety Screening
Problem:A patient rates: nervous (2), can't stop worrying (2), worrying too much (2), trouble relaxing (1), restless (1), irritable (2), afraid (1).
Solution:Item scores: 2 + 2 + 2 + 1 + 1 + 2 + 1 = 11 Score range: 0-21 Severity: Moderate Anxiety (10-14 range) Above clinical threshold of 10: Yes Worry domain (items 1-3): 6/9 Physical domain (items 4-5): 2/6 Emotional domain (items 6-7): 3/6 Recommendation: Further clinical evaluation recommended
Result:Total Score: 11/21 | Moderate Anxiety | Clinical evaluation recommended
Example 2: Severe Anxiety Assessment
Problem:A patient reports nearly every day for most symptoms: nervous (3), can't stop worrying (3), worrying too much (3), trouble relaxing (2), restless (2), irritable (3), afraid (2).
Solution:Item scores: 3 + 3 + 3 + 2 + 2 + 3 + 2 = 18 Score range: 0-21 Severity: Severe Anxiety (15-21 range) Above clinical threshold of 10: Yes Worry domain (items 1-3): 9/9 (maximum) Physical domain (items 4-5): 4/6 Emotional domain (items 6-7): 5/6 Recommendation: Active treatment strongly recommended
Result:Total Score: 18/21 | Severe Anxiety | Active treatment recommended
Frequently Asked Questions
What is the GAD-7 and what does it measure?
The GAD-7 (Generalized Anxiety Disorder 7-item scale) is a validated screening tool developed by Drs. Robert Spitzer, Janet Williams, and Kurt Kroenke in 2006. It measures the severity of generalized anxiety disorder symptoms over the past two weeks. The questionnaire consists of seven items rated on a four-point Likert scale from 0 (not at all) to 3 (nearly every day), producing a total score ranging from 0 to 21. It is widely used in primary care settings, mental health clinics, and research studies as a brief, reliable screening instrument for anxiety. The GAD-7 has strong psychometric properties with a sensitivity of 89% and specificity of 82% for detecting generalized anxiety disorder.
How are GAD-7 scores interpreted and what do the cutoffs mean?
GAD-7 scores are divided into four severity categories: 0 to 4 represents minimal anxiety, 5 to 9 indicates mild anxiety, 10 to 14 suggests moderate anxiety, and 15 to 21 indicates severe anxiety. A score of 10 or higher is commonly used as the clinical threshold suggesting a probable anxiety disorder diagnosis, warranting further evaluation by a mental health professional. However, the GAD-7 is a screening tool and not a diagnostic instrument. A formal diagnosis requires a comprehensive clinical assessment including a structured diagnostic interview, review of medical history, and consideration of other potential causes. Higher scores correlate with greater functional impairment and disability days.
Can the GAD-7 detect other anxiety disorders besides generalized anxiety?
While the GAD-7 was originally developed to screen for generalized anxiety disorder, research has shown it has reasonable sensitivity for detecting other common anxiety disorders as well. Studies indicate it performs well as a screener for panic disorder (sensitivity 74%), social anxiety disorder (sensitivity 72%), and post-traumatic stress disorder (sensitivity 66%). However, its specificity for these conditions is lower than for generalized anxiety disorder. For more targeted screening, disorder-specific instruments such as the PHQ-Panic, the Social Phobia Inventory (SPIN), or the PTSD Checklist (PCL-5) may be more appropriate. The GAD-7 is best considered a general anxiety severity measure rather than a disorder-specific diagnostic tool.
How often should the GAD-7 be administered?
The GAD-7 is designed to assess symptoms over the preceding two-week period, so it can be administered every two weeks to monitor changes in anxiety severity. In clinical practice, it is commonly used at initial assessment and then at regular follow-up intervals to track treatment response. Many clinicians administer it monthly during active treatment to evaluate whether therapy or medication is effectively reducing symptoms. A clinically meaningful change is generally considered to be a 5-point reduction in score. For patients in remission, quarterly or semi-annual screenings may be sufficient to monitor for relapse. In research settings, the GAD-7 is often administered at baseline, mid-treatment, and post-treatment to document outcomes.
What are the limitations of the GAD-7 as an anxiety assessment tool?
The GAD-7 has several important limitations that clinicians and patients should understand. It relies entirely on self-report, which can be affected by recall bias, social desirability, or poor insight into symptoms. It does not assess the duration criterion required for a GAD diagnosis (symptoms present for at least six months). The tool cannot distinguish between primary anxiety and anxiety secondary to medical conditions, substance use, or other psychiatric disorders. Cultural factors may influence how individuals interpret and respond to the questions. The GAD-7 does not assess specific phobias, obsessive-compulsive disorder, or separation anxiety disorder effectively. It should always be used as one component of a comprehensive clinical evaluation rather than as a standalone diagnostic instrument.
What is the GAD-2 and how does it relate to the GAD-7?
The GAD-2 is the first two items of this scale, covering feeling nervous or on edge and being unable to stop or control worrying, scored the same 0 to 3 way for a range of 0 to 6. It exists as an ultra-brief first pass in busy settings: a negative result usually ends the screen, while a positive one prompts the full seven items. Because it samples only the core worry symptoms, it trades some accuracy for speed and is never used on its own to characterise severity.
Are the worry, physical and emotional domain subscores part of the validated instrument?
No. The GAD-7 was validated as a single total score, and its severity bands refer to that total. The three groupings shown here simply split the seven items into cognitive worry, restlessness and tension, and irritability and apprehension, as a way of seeing which kind of symptom is driving your number. They have no published cut-points and should not be reported as if they were scored subscales. Only the 0 to 21 total carries the psychometric evidence.
Why are the GAD-7 and the PHQ-9 so often used together?
They come from the same family of brief self-report measures and share the two-week recall window and the 0 to 3 response format, so they can be completed side by side in a couple of minutes. Clinically they are paired because anxiety and depressive symptoms overlap heavily and frequently occur together, and symptoms such as poor sleep, restlessness and difficulty concentrating appear in both clinical pictures even where they are not items on both questionnaires. Administering only one risks attributing a shared symptom entirely to the condition you happened to screen for.
What does the extra functional impairment question on the standard form add?
The published GAD-7 form ends with an unscored item asking how difficult these problems have made it to do work, take care of things at home or get along with other people. It is not added to the 0 to 21 total, but it captures impairment, which is what usually separates distressing symptoms from a clinical presentation. Two people can report the same total while differing greatly in how much their daily functioning is affected, and that difference matters more than the number itself.
What besides an anxiety disorder can raise a GAD-7 score?
The items describe symptoms, not causes. Heavy caffeine intake, poor or shortened sleep, alcohol or stimulant use and withdrawal states, some prescribed medications, thyroid and other endocrine conditions, and an ongoing life stressor such as bereavement or job loss can all produce genuine anxiety symptoms and a raised total. That is exactly why this result is a screening prompt rather than an answer: interpreting it, and ruling those causes in or out, belongs with a clinician who can take a full history.
