Feeling nervous, restless, or constantly worried? It’s normal to experience these feelings from time to time, but when they become persistent and overwhelming, it might be a sign of anxiety. Understanding your mental health is the first step towards well-being. A helpful tool for initial self-assessment is the Generalized Anxiety Disorder 7-item scale, or GAD-7. This simple questionnaire can provide insights into your anxiety levels and help you determine if seeking further professional evaluation is necessary. Let’s explore how you can use the GAD-7 for Anxiety Self Diagnosis.
The GAD-7 is a widely used and validated tool designed to screen for generalized anxiety disorder (GAD) and other anxiety-related conditions. Developed by Drs. Robert L. Spitzer, Janet B.W. Williams, Kurt Kroenke, and their colleagues, this brief questionnaire helps individuals reflect on their anxiety symptoms over the past two weeks. It’s important to remember that the GAD-7 is a screening tool and not a substitute for a professional diagnosis. However, it can be a valuable starting point for understanding your feelings and deciding on the next steps for your mental health journey.
Taking the GAD-7: The Questionnaire
Consider the following questions and reflect on how often you have been bothered by each issue over the last 2 weeks. For each question, choose the option that best describes your experience: “Not at all”, “Several days”, “More than half the days”, or “Nearly every day”.
GAD-7 Questionnaire:
-
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 that it is hard to sit still
-
Becoming easily annoyed or irritable
-
Feeling afraid as if something awful might happen

Scoring and Interpretation
Once you have completed the questionnaire, calculate your total score by assigning points to each response as follows:
- Not at all: 0 points
- Several days: 1 point
- More than half the days: 2 points
- Nearly every day: 3 points
Sum the points for all seven questions to get your total GAD-7 score. This score helps to interpret the severity of your anxiety symptoms.
The interpretation of your GAD-7 score is as follows:
- Score 0-4: Minimal Anxiety – Your symptoms are minimal and likely not significantly impacting your daily life.
- Score 5-9: Mild Anxiety – You are experiencing mild anxiety. It might be beneficial to monitor your symptoms and consider lifestyle changes to manage stress.
- Score 10-14: Moderate Anxiety – You are experiencing moderate anxiety. Seeking professional advice from a healthcare provider could be helpful to discuss coping strategies and potential treatment options.
- Score greater than 15: Severe Anxiety – You are experiencing severe anxiety. It is highly recommended to seek professional help from a doctor or mental health professional for a comprehensive evaluation and treatment plan.
A score of 8 or greater is considered a significant cut-off point. Research indicates that a score in this range suggests a reasonable probability of generalized anxiety disorder and warrants further diagnostic assessment by a healthcare professional. It’s important to note that these score ranges are guidelines, and individual experiences can vary.

GAD-7 as a Screening Tool for Other Anxiety Disorders
While primarily designed for generalized anxiety disorder, the GAD-7 is also a useful screening tool for other common anxiety disorders, including Panic Disorder, Social Anxiety Disorder, and Posttraumatic Stress Disorder (PTSD). Research has shown that the GAD-7 demonstrates reasonable accuracy in identifying these conditions as well.
The table below illustrates the performance of the GAD-7 as a screening tool for various anxiety disorders when using a score cut-off of ≥10.
| Test | Sensitivity | Specificity | Positive Likelihood Ratio |
|---|---|---|---|
| Generalized Anxiety Disorder | 89% | 82% | 5.1 |
| Panic Disorder | 74% | 81% | 3.9 |
| Social Anxiety Disorder | 72% | 80% | 3.6 |
| Post-Traumatic Stress Disorder | 66% | 81% | 3.5 |
| Any anxiety disorder | 68% | 88% | 5.5 |
(Alt Text: GAD-7 Performance as Screening Tool for Various Anxiety Disorders – Sensitivity and Specificity at a score cutoff of 10. This table displays the sensitivity, specificity, and positive likelihood ratio of the GAD-7 for screening Generalized Anxiety Disorder, Panic Disorder, Social Anxiety Disorder, Post-Traumatic Stress Disorder, and any anxiety disorder.)
This data indicates that a higher GAD-7 score can suggest the possibility of various anxiety disorders, highlighting its broad utility in initial mental health assessments.
Limitations and Next Steps
It’s crucial to reiterate that the GAD-7 is a screening tool, not a diagnostic instrument. A high score on the GAD-7 does not definitively mean you have an anxiety disorder. It simply suggests that further evaluation by a qualified mental health professional is recommended. A professional can conduct a comprehensive assessment, considering your individual history, symptoms, and other factors to provide an accurate diagnosis and recommend appropriate treatment if needed.
If your GAD-7 score indicates mild, moderate, or severe anxiety, or if you are concerned about your anxiety levels regardless of your score, reaching out to a healthcare provider is a proactive step. They can provide guidance, support, and connect you with resources to manage your anxiety and improve your overall well-being. Anxiety self diagnosis using tools like the GAD-7 is a helpful first step, but professional consultation is essential for accurate diagnosis and effective management.
In conclusion, the GAD-7 questionnaire is a valuable resource for anxiety self diagnosis. It offers a quick and reliable way to assess your anxiety symptoms and understand their potential severity. By taking this self-assessment, you can gain valuable insights into your mental health and take informed steps towards seeking support and improving your well-being. Remember, taking care of your mental health is just as important as taking care of your physical health.
