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 through 4 (based on these replies: "a little of the time," "some of the time," "good part of the time," "most of the time").
Scores on the test range from 20 through 80. The scores fall into four ranges:
- 20-49 Normal Range
- 50-59 Mildly Depressed
- 60-69 Moderately Depressed
- 70 and above Severely Depressed
