The GAD-7 is a brief questionnaire that individuals can complete in a few minutes. It asks about feelings of nervousness, worry, and restlessness, among other symptoms. Each question is scored on a scale from 0 (not at all) to 3 (nearly every day). The total score ranges from 0 to 21, with higher scores indicating more severe anxiety. A score of 10 or above typically suggests clinically significant anxiety.
