Typical social situations can be grouped into those that involve interaction, observation and performance.

As set out in the International Classification of Diseases, 10th Revision (ICD-10) ( World Health Organization, 1992) and in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition Text Revision (DSM-IV-TR) ( American Psychiatric Association, 2000) social anxiety disorder is a persistent fear of one or more social situations where embarrassment may occur and the fear or anxiety is out of proportion to the actual threat posed by the social situation as determined by the person's cultural norms. The term ‘social anxiety disorder’ reflects current understanding, including in diagnostic manuals, and is used throughout the guideline. Social anxiety disorder (previously termed ‘social phobia’) was formally recognised as a separate phobic disorder in the mid-1960s ( Marks & Gelder, 1965).
