The Beck Anxiety Inventory (BAI) is a self-report questionnaire designed to measure the severity of anxiety symptoms. It is one of the most widely used anxiety assessment tools in clinical settings, research, and treatment monitoring.
The BAI consists of 21 items that assess the frequency of various anxiety symptoms, such as feeling restless, on edge, or having trouble concentrating. Each item is rated on a four-point scale, ranging from 0 (not at all) to 3 (severely). The total score ranges from 0 to 63, with higher scores indicating greater anxiety severity.
