Social Phobia Inventory (
SPIN) is a
questionnaire developed by the department of Psychiatry and Behavioral Sciences of
Duke University for
screening and measuring severity of
social anxiety disorder. This self-reported assessment scale consists of 17 items, which cover the main spectrum of social phobia such as fear, avoidance, and physiological symptoms. The statements of the SPIN items indicate the particular signs of social phobia. Answering the statements a person should indicate how much each statement applies to him or her.
