Measures severity of anxiety symptoms over the past 2 weeks
⚠️ IMPORTANT CLINICAL NOTE
This tool is intended for use by healthcare professionals only. While the GAD-7 may be administered to patients, it should be interpreted in the context of a clinical assessment and cannot replace a comprehensive diagnostic evaluation by a qualified mental health professional.
Ask the patient: "Over the last 2 weeks, how often have you been bothered by the following problems?"
Routine monitoring; no specific intervention needed
5-9
Mild
Monitor symptoms; consider watchful waiting or brief intervention
10-14
Moderate
Further assessment (diagnostic interview, mental status exam) and/or referral to mental health professional recommended
15-21
Severe
Active treatment (psychotherapy and/or pharmacotherapy) warranted; urgent assessment recommended
⚡ CRITICAL CLINICAL ACTIONS
This screening tool cannot replace a comprehensive clinical assessment and diagnosis
Always rule out medical causes of anxiety before diagnosing an anxiety disorder (e.g., EKG for arrhythmias, TSH for thyroid disease)
For Panic Disorder, Social Phobia, and PTSD, a cutoff score of 8 may provide optimal sensitivity/specificity
Consider suicide risk assessment in all patients with elevated anxiety scores
How to Use This GAD-7 Calculator
The GAD-7 (General Anxiety Disorder-7) is a validated 7-item self-report questionnaire used to screen for and measure the severity of generalized anxiety disorder. Follow these steps for accurate assessment:
Administer the questionnaire: Have the patient answer all 7 questions based on their experiences over the past 2 weeks.
Select responses: For each symptom, choose the appropriate frequency: "Not at all," "Several days," "More than half the days," or "Nearly every day."
Review the score: The total score (0-21) will be calculated automatically and displayed with the corresponding severity level.
Interpret the results: Use the clinical management table to guide next steps based on the severity category.
Consider clinical context: Remember that the GAD-7 is a screening tool and should be interpreted within the context of a full clinical assessment.
Download results: Use the PDF download feature to save the results for patient records or consultation notes.

Frequently Asked Questions
What is the GAD-7 used for?
+
The GAD-7 is a 7-item self-report questionnaire designed to screen for generalized anxiety disorder and measure anxiety symptom severity. It is commonly used in primary care and mental health settings to identify patients who may need further assessment for anxiety disorders.
How is the GAD-7 score calculated?
+
Each of the 7 items is scored from 0 to 3, with 0 representing "Not at all" and 3 representing "Nearly every day." The total score is the sum of all 7 items, ranging from 0 to 21. Higher scores indicate greater anxiety severity.
What do the different score ranges mean?
+
0-4: Minimal anxiety - no clinically significant anxiety
5-9: Mild anxiety - may not require treatment
10-14: Moderate anxiety - further assessment recommended
15-21: Severe anxiety - active treatment warranted
Can the GAD-7 diagnose anxiety disorders?
+
No, the GAD-7 is a screening tool, not a diagnostic instrument. A positive screen (typically ≥10) indicates the need for a comprehensive diagnostic assessment by a qualified mental health professional to confirm the presence of an anxiety disorder.
How often should the GAD-7 be administered?
+
The GAD-7 can be administered at initial assessment and then periodically (e.g., every 4-8 weeks) to monitor treatment progress. In clinical trials, it is often used as a primary outcome measure to track symptom changes over time.
Is this calculator suitable for self-assessment?
+
While patients can complete the GAD-7 questions, interpretation should always be done by a qualified healthcare professional. This tool is designed for clinical use and should not replace professional medical evaluation, diagnosis, or treatment.
