The Zung Self-Rating Anxiety Scale (SAS) was designed by William W. K. Zung, a psychiatrist from Duke University, to quantify a patient's level of anxiety.
The SAS scale is designed similar to a customer service survey questionnaire. It is a 20-item self-report assessment device build to measure anxiety levels, based on scoring in 4 groups of manifestations: cognitive, autonomic, motor and central nervous system symptoms. Answering the statements a person should indicate how much each statement applies to him or her. Each question is scored on a Likert-type scale of 1-4 (based on these replies: "a little of the time," "some of the time," "good part of the time," "most of the time"). Overall assessment is done by total score.
The total scores range from 20-80.
- 20-44 Normal Range
- 45-59 Mild to Moderate Anxiety Levels
- 60-74 Marked to Severe Anxiety Levels
- 75-80 Extreme Anxiety Levels
Famous quotes containing the words anxiety and/or scale:
“Perhaps anxious politicians may prove that only seventeen white men and five negroes were concerned in the late enterprise; but their very anxiety to prove this might suggest to themselves that all is not told. Why do they still dodge the truth? They are so anxious because of a dim consciousness of the fact, which they do not distinctly face, that at least a million of the free inhabitants of the United States would have rejoiced if it had succeeded. They at most only criticise the tactics.”
—Henry David Thoreau (1817–1862)
“There is something in us, somehow, that, in the most degraded condition, we snatch at a chance to deceive ourselves into a fancied superiority to others, whom we suppose lower in the scale than ourselves.”
—Herman Melville (1819–1891)
