Quick answer
The GAD-7 is a brief, widely-used questionnaire that screens for and measures the severity of generalized anxiety. It has seven items about anxiety symptoms over the past two weeks, scored to indicate mild, moderate, or severe anxiety. It's a screening and monitoring tool used by clinicians — helpful, but not a diagnosis on its own.
What it is
The GAD-7 (Generalized Anxiety Disorder 7-item scale) is one of the most widely used anxiety questionnaires in healthcare. It consists of seven questions asking how often, over the past two weeks, you've been bothered by common anxiety symptoms — things like feeling nervous or on edge, not being able to stop or control worrying, worrying too much, trouble relaxing, restlessness, irritability, and feeling afraid something awful might happen. Each item is scored (based on frequency), and the total gives a measure of anxiety severity. It's quick to complete — usually a minute or two — which is part of why it's so widely used.
How it's scored and used
The GAD-7 produces a total score that maps to severity categories — typically ranging from minimal, through mild and moderate, to severe anxiety — with recognized thresholds that flag when anxiety is likely clinically significant. Clinicians use it in several ways: to screen for anxiety (a raised score prompts fuller assessment), to gauge how severe someone's anxiety is, and — very usefully — to track changes over time, since repeating it during treatment shows whether symptoms are improving. Although designed for generalized anxiety, it also performs reasonably as a general anxiety screen and can pick up other anxiety disorders. Its brevity, validation, and usefulness for monitoring make it a standard tool.
What it can and can't do
The GAD-7 is a validated, genuinely useful screening and measurement tool — but it's important to understand its role. It indicates the likelihood and severity of anxiety and tracks change well, but it doesn't by itself diagnose an anxiety disorder or distinguish between the different types — that requires a clinician's full assessment. A high score suggests anxiety is likely and worth professional evaluation, not that you definitely have a specific disorder. For your own use, it can be a helpful gauge and a prompt to seek help if your score is elevated, and a useful way to track your progress in treatment. But treat it as a helpful thermometer, not a final verdict — and let a professional provide the actual diagnosis and treatment plan.
What tests can and can't do
Screening questionnaires are conversation starters, not verdicts. A high score means 'worth discussing with a professional,' and a low score doesn't invalidate your struggle. Only a qualified clinician can diagnose an anxiety disorder — and a diagnosis is a doorway to help, not a label that defines you.
