Who it is for
Adults who want a structured, private check of anxiety symptoms experienced during the past two weeks.
What your result can show
The seven responses are summed to a score from 0 to 21 and shown in the GAD-7's published symptom ranges. The result is suitable as a conversation prompt, not as a diagnosis.
Important limitations
The GAD-7 is a screening measure, not a diagnostic assessment. Other conditions, circumstances and physical health factors can produce similar symptoms and require qualified evaluation.
A higher score does not establish a diagnosis. A lower score does not show that a condition is absent.
