Self-Rating Anxiety Scale (SAS)

The Self-Rating Anxiety Scale (SAS) was developed by William W.K. Zung in 1971 and remains one of the most widely used anxiety screening tools in clinical and research settings. It assesses the frequency of anxiety symptoms over the past week across cognitive, affective, and somatic domains. The scale covers symptoms such as nervousness, panic, trembling, nightmares, difficulty breathing, and digestive issues. It's designed to capture both the psychological experience of anxiety and its physical manifestations. While the SAS is a valuable screening tool, it's not a diagnostic instrument. High scores indicate the need for professional evaluation. This test can help you recognize anxiety patterns and decide whether to seek support from a mental health professional.
