Zung

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.

History

The Zung Self-Rating Depression Scale was created by Dr. William W. K. Zung. Dr. Zung was a psychiatrist who developed several self-report measures for assessing levels of depression and anxiety. His scales are used worldwide by clinicians and researchers.

Structure

The scale consists of 20 items, each rated on a scale of 1-4 (a little of the time, some of the time, good part of the time, most of the time). Ten of the items are worded positively, ten are worded negatively. The total score ranges from 20-80.

Scoring

The scores fall into four categories:

• 20-44 Normal Range
• 45-59 Mildly Depressed
• 60-69 Moderately Depressed
• 70 and above Severely Depressed

Use

The Zung Self-Rating Depression Scale is used by clinicians and researchers worldwide to detect depression in patients. It is not intended to make a diagnosis of depression, but to assess the severity of symptoms and monitor treatment progress.
