Beck Anxiety Inventory The Beck Anxiety Inventory (BAI), created by Aaron T. Beck and other colleagues, is a 21-question multiple-choice self-report inventory that is used for measuring the severity of anxiety in children and adults. The questions used in this measure ask about common symptoms of anxiety that the subject has had during the past week (including the day you take it). I designed it for individuals who are of 17 years of age or older and takes 5 to 10 minutes to complete. Several studies have found the Beck Anxiety Inventory to be an accurate measure of anxiety symptoms in children and adults.  Scoring and Interpretation The BAI contains twenty-one questions, each answer being scored on a scale value of 0 (not at all) to 3 (severely). Higher total scores indicate more severe anxiety symptoms. The standardized cut-offs are: 0–9: normal to minimal anxiety 10–18: mild to moderate anxiety 19–29: moderate to severe anxiety 30–63: severe anxiety Minimum score 0 max 63 Evidence T
