WHAT THE TEST MEASURES

About This Assessment

Zung Self-Rating Anxiety Scale (SAS) Test - Symptoms and Signs

anxiety disorder uneasiness

Anxiety symptoms are a common focus of clinical evaluation, and the Zung Self-Rating Anxiety Scale (SAS) is a brief self-report measure used to estimate current anxiety severity. It is typically administered as a screening tool and may also be used to monitor change over time.

The scale consists of 20 items and is usually completed in about 4 minutes. Items reflect a range of somatic and affective symptoms; respondents indicate how frequently they have experienced each symptom recently, supporting a standardized summary of self-reported anxiety-related distress.

In clinical practice, the Zung Self-Rating Anxiety Scale (SAS) can inform initial case formulation, guide discussion of symptom burden, and provide a quantitative reference point for follow-up assessments. Results should be interpreted within the broader clinical context and are not, by themselves, diagnostic.
