How much is anxiety affecting you?
Anxiety shows up differently for different people. For some it's a racing heart and sweaty palms. For others it's a constant hum of worry that won't shut off. And for many, it's both.
The SAS measures anxiety symptoms across both psychological and physical domains. Zung created it in 1971, and it's been in steady use ever since. It asks about 20 common anxiety symptoms — things like feeling nervous, having a pounding heart, getting dizzy spells, or having nightmares.
Each item is rated on a 1-4 scale based on how often you've experienced it over the past week. The total converts to an anxiety index.
It's widely used as a screening tool, not a diagnostic instrument. Think of it as an early signal, not a final answer.
