The Zung Self-Rating Depression Scale was designed by Duke University psychiatrist Dr. William W.K. Zung to assess the level of depression for patients diagnosed with depressive disorder.^[1]

The Zung Self-Rating Depression Scale is a short self-administered survey to quantify the depressed status of a patient. There are 20 items on the scale that rate the rating affective, psychological and somatic symptoms associated with depression.^{[citation needed]}

There are ten positively worded and ten negatively worded questions. Each question is scored on a scale of 1 through 4 (based on these replies: "a little of the time," "some of the time," "good part of the time," "most of the time").^{[citation needed]}

Scores on the test range from 20 through 80. The scores fall into four ranges:^{[citation needed]}

• 20-49 Normal Range
• 50-59 Mildly Depressed
• 60-69 Moderately Depressed
• 70 and above Severely Depressed

The Zung Self-Rating Depression Scale has been translated into many languages, including Arabic ^[2], Azerbaijani^[3], Dutch, German, Portuguese ^[4], Spanish ^[5] and others.
