Zung Self-Rating Anxiety Scale (SAS)

The Zung Self-Rating Anxiety Scale (SAS) is a psychological assessment tool developed by Dr. William W. K. Zung in 1971. It is designed to measure the severity of anxiety symptoms in individuals. The scale consists of 20 items, each scored on a four-point scale ranging from “none or a little of the time” to “most or all of the time.” This self-administered questionnaire is utilized in both clinical and research settings to evaluate the presence and intensity of anxiety symptoms. The SAS is designed to be simple and straightforward, enabling individuals to complete it without the need for professional supervision. 

How to Take the Assessment:

1. Access the Test: Visit the Psychology Tools website to access the Zung Self-Rating Anxiety Scale.

2. Read Each Statement Carefully: The assessment consists of 20 statements related to anxiety symptoms.

3. Select the Appropriate Response: For each statement, indicate how often you have experienced the described feeling or behavior during the past several days by choosing one of the following options:

   • None or a little of the time

   • Some of the time

   • Good part of the time

   • Most or all of the time.

4. Complete All Items: Ensure that you respond to all 20 items to obtain an accurate assessment.

5. Review Your Score: After completing the questionnaire, your responses will be tallied to provide a total score, which can help indicate the severity of your anxiety symptoms.

Interpreting Your Score:

The total score ranges from 20 to 80, with higher scores indicating greater levels of anxiety

• 20–44: Normal Range

• 45–59: Mild to Moderate Anxiety Levels

• 60–74: Marked to Severe Anxiety Levels

• 75–80: Extreme Anxiety Levels
