Classic anxiety scale by Zung (1971). 20 items.

What Is the Zung Self-Rating Anxiety Scale (SAS)?

Feel like you're running on edge all the time, but not sure if it's anxiety or just a rough week? The SAS cuts through the noise with 20 straightforward questions — half about how you feel (nervous, panicked), half about what your body's doing (racing heart, shaky hands, trouble breathing).

Each item uses a simple 1-4 scale. Tally up your score and you'll get a rough sense of where you land, from normal range to severe anxiety. It takes about 5 minutes.

Where It Came From

William Zung put this together in 1971, and it's held up surprisingly well. The questions focus on symptoms that cut across different types of anxiety — which means it catches things a narrower scale might miss. That said, it's a screening tool, not a diagnosis. Think of it as a signal, not a verdict.
