Zung Self-Rating Depression Scale
From Wikipedia, the free encyclopedia
The Zung Self-Rating Depression Scale was designed by W.W. Zung to assess the level of depression for patients diagnosed with depressive disorder.
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 four common characteristics of depression: the pervasive effect, the physiological equivalents, other disturbances, and psychomotor activities.
There are ten positively worded and ten negatively worded questions. Each question is scored on a scale of 1-4 (a little of the time, some of the time, good part of the time, most of the time).
The scores range from 25-100.
- 25-49 Normal Range
- 50-59 Mildly Depressed
- 60-69 Moderately Depressed
- 70 and above Severely Depressed
