This post is a quick link to information from guardian.co.uk, a well regarded British newspaper. They provide the questions and rating scales for the Hamilton Anxiety Scale, the State-Trait Anxiety Inventory, the Beck Anxiety Inventory and the Penn State Worry Questionnaire. These rating scales are widely used in the profession.
You can view them at this link.
A word of caution. Diagnoses are not made by these tests. They reflect a level of anxiety at a given point in time. They are certainly not meant to replace a thorough evaluation by a trained medical professional. If you are concerned that you may have an anxiety disorder, please seek out professional counseling and care. These ratings scales do not offer any treatment or medical advice.
