Our anxiety calculator is based on the Back Anxiety Inventory (BAI), which was developed by Dr. Aaron T. Beck and his colleagues.
The BAI is a 21-question multiple-choice self-report inventory, commonly used for measuring the severity of anxiety in children and adults.
It is designed for individuals who are of 17 years of age or older and takes about 5 minutes to complete.
Several studies have found the Beck Anxiety Inventory to be one of the most accurate measures of anxiety symptoms.
