The Zung Self-Rating Depression Scale was designed by Duke University psychiatrist William W.K. Zung MD (1929-1992) 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 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]

  • 20-44 Normal Range
  • 45-59 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] and Spanish.[5]
