GAD-7 Calculator
Score the GAD-7 anxiety questionnaire and interpret minimal, mild, moderate, or severe anxiety severity.
What Is the GAD-7?
The Generalized Anxiety Disorder 7-item scale (GAD-7) is a brief questionnaire that screens for anxiety severity over the past two weeks. It asks how often the patient was bothered by seven core anxiety symptoms. Each item scores 0 to 3 by frequency, for a total range of 0 to 21.
Scoring and Severity Bands
Scores of 0 to 4 suggest minimal anxiety. Scores of 5 to 9 indicate mild anxiety. Scores of 10 to 14 suggest moderate anxiety. Scores of 15 to 21 suggest severe anxiety. A score of 10 or higher often warrants further clinical evaluation. Because anxiety and depression frequently overlap, consider pairing results with the PHQ-2 Depression Screening Calculator or full PHQ-9 when mood symptoms are present.
Frequency Response Options
Not at all scores 0, several days scores 1, more than half the days scores 2, and nearly every day scores 3. All seven items must be answered to compute a valid total score.
Frequently Asked Questions
What GAD-7 score suggests follow-up is needed?
Scores of 10 or higher are commonly used as a threshold for further assessment. Mild scores may still warrant discussion if symptoms impair function.
Does the GAD-7 diagnose generalized anxiety disorder?
No. GAD-7 is a screening and severity measure. Diagnosis requires clinical interview against DSM or ICD criteria.
What symptoms does the GAD-7 cover?
Nervousness, uncontrollable worry, excessive worry, trouble relaxing, restlessness, irritability, and fear that something awful might happen.
How often should the GAD-7 be repeated?
In primary care, repeat at follow-up visits to track response to treatment. The same two-week recall period applies each time.
Can I use GAD-7 in pregnancy or postpartum?
GAD-7 is used in perinatal settings as a screening aid. Always interpret results in context and coordinate perinatal mental health care when scores are elevated.
