title: Social anxiety and its relationship to functional impairment in body dysmorphic disorder.
abstract: Social anxiety appears to be a prominent characteristic of body dysmorphic disorder (BDD). However, few previous studies have examined social anxiety and its facets (i.e., physiological arousal, fear and avoidance of social situations) and their relationship to psychosocial functioning in BDD. The present study aimed to fill these gaps by examining (a) social anxiety and its facets in BDD, and b) cross-sectional and prospective relationships between social anxiety symptoms and functional impairment in BDD. Individuals with DSM-IV BDD without comorbid social phobia (N=108) completed measures of social anxiety and psychosocial functioning at study intake (T1). Psychosocial functioning was also assessed at a 12-month follow-up interview (T2). Severity of social anxiety (i.e., due to BDD or any other source) was rated with the Social Phobia Inventory (SPIN). In addition, participants were interviewed with the Duke Brief Social Phobia Scale (BSPS) to assess social anxiety independent of BDD. At T1, participants endorsed high levels of social anxiety on the SPIN and subclinical levels of social anxiety on the BSPS. Greater social anxiety was associated with poorer psychosocial functioning in cross-sectional and prospective analyses, particularly fear and avoidance of social situations. These results suggest that certain aspects of social anxiety, especially social fear and avoidance, may be significant contributing factors to functional impairment in individuals with BDD.
