Social phobia is a common anxiety disorder associated with significant impairment in social and occupational functioning. To date, few studies have examined the relationship between social phobia and perceived social support, a construct with important relationships to physical and mental health. The present study examined data from 2 widely used measures of perceived social support administered to 132 individuals with DSM-IV generalized social phobia. These data were compared with those obtained from a healthy control group and from several clinical and non-clinical samples reported in the literature. Persons with generalized social phobia scored significantly lower on both measures of social support compared with all other groups. It is suggested that deficits in perceived social support associated with generalized social phobia may play a role in the development of co-morbid problems and should be explicitly targeted by treatments for social phobia. Low correlations between perceived social support and social anxiety measures suggest that perceived support should be specifically evaluated in this population.
