The Zung depression scale
The Zung Self-Rating Depression Scale is a widely used depression screening tool used to rate the level of depression in patients with diagnosed depressive disorders.
The Zung Depression Scale is provided as a self-administered online depression test. There are 20 multiple choice questions which are rated on a scale of 1 to 4 based on 4 different answers.
The majority of people that have depression rate between 50 to 69, while a rating of 70 and more is an indication of severe depression. The ratings provide a general indication of depression severity, but the Zung Depression Scale cannot take the place of a trained healthcare provider for confirmation of a depression diagnosis. The Zung Depression Scale can also be a useful tool for tracking changes in the severity of depression.
The reliability of the Zung Depression Scale has been proven in several studies to be adequate in determining the severity of depression.
