Zung Self-Rating Depression Scale (SDS)

A quick and easy way of finding out if you show signs of depression.

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).
