How to Use GAD-7 Calculator
The GAD-7 Calculator scores seven anxiety screening items. For each item, select the frequency that best matches the last two weeks: not at all, several days, more than half the days, or nearly every day. The calculator adds all seven item scores and shows the total from 0 to 21.
The result panel reports the corresponding anxiety band: minimal, mild, moderate, or severe. It also displays the score range and formula so users can understand that the total is a direct sum, not a weighted score.
The GAD-7 is a screening and symptom-tracking tool. A high score can support a conversation about anxiety, but it is not a diagnosis by itself. Panic symptoms, trauma, depression, substance use, medical illness, medications, and safety concerns all require broader assessment.
