Depression, Anxiety & Stress Scale (DASS-21)
One test, three results: depression, anxiety and stress.
About this test
The DASS-21 measures three related states at once — depression, anxiety and stress — on three separate scales. Each scale is scored on its own, so you get three results. It is in the public domain and free to use.
