The Zung Self-Rating Depression Scale (SDS) is a depression self-test that measures your current depression level. It was originally developed by W.W. Zung to test the level of depression in patients diagnosed with depression.
The Zung self-rating depression scale assesses the various psychological as well as somatic symptoms associated with depression. It measures common characteristics of depression- the pervasive effect, physiological equivalents, psychomotor activities, and other disturbances.
Taking the Zung depression test
The test consists of 20 items on a 4-point scale ranging from ‘A little of the time’ to ‘Most of the time’. Based on your score, you’ll be classified into one of the different depression ranges– Normal range, Mildly depressed, Moderately depressed, and Severely depressed.
While answering the items, think about what describes you most accurately for the past several days.
You’ll obtain the test results instantly after you finish the questionnaire and hit the ‘Submit’ button. Your personal information will not be collected and your test results won’t be stored in our database. The test takes around 5-10 minutes to complete.
In case the results show that you’re depressed, it’s recommended that you consult with a mental health professional for a more thorough analysis. Results from a battery of tests are always more reliable than from a single test.
