Understand and evaluate your depression level using the Zung Self-Rating Depression Scale.
The Zung Self-Rating Depression Scale (SDS) is an instrument used for measuring the presence and severity of depressive symptoms in individuals. Developed by Dr. William WK Zung, this scale has been widely employed in various settings to assess depression and its associated factors across diverse populations.
Dr. Zung meticulously developed the SDS through a systematic approach, which included reviewing existing literature on depression and identifying common symptoms associated with the disorder. The initial set of items was refined through pilot testing and psychometric analysis, resulting in a reliable and valid scale. The final version of the SDS, consisting of 20 items, was established after several iterations to ensure its effectiveness in assessing depression.
The SDS features 20 items, each rated on a scale from 1 (none or some of the time) to 4 (most or all of the time). The total score ranges from 20 to 80, with higher scores indicating more severe depressive symptoms. The scale is designed to measure the affective, psychological, and somatic aspects of depression, enabling clinicians to better understand and diagnose the condition in their patients.
