Questionnaire / instrument: GAD-7
What does it measure?
The frequency of seven symptoms associated with generalized anxiety over the past two weeks, including worry, tension, restlessness and difficulty relaxing.
Where does it come from?
GAD-7 was developed by Robert Spitzer, Kurt Kroenke, Janet Williams and Bernd Löwe and published in 2006. The questionnaire was developed with educational support from Pfizer.
How is the result calculated?
Each answer contributes 0–3 points, giving a total of 0–21. Published severity thresholds are 5, 10 and 15. Our version uses the seven scored questions; the separate question about daily-life difficulty is not included.
What can the result tell you?
GAD-7 screens for symptoms and their severity; it does not establish a diagnosis or explain their cause. A score of 10 or more is commonly used to flag further assessment. The score is not the probability that you have an anxiety disorder.
