Phenomenology and Epidemiology of Body Dysmorphic Disorder
Body dysmorphic disorder (BDD) is an often severe DSM-IV disorder characterized by distressing or impairing preoccupations with imagined or slight defects in appearance. Individuals with BDD suffer from time-consuming obsessions about their bodily appearance and excessive repetitive behaviors (for example, mirror checking, excessive grooming, and skin picking). Functioning and quality of life are typically very poor, and suicidality rates appear markedly elevated. While prevalence data are still limited, they suggest that BDD affects 0.7% to 2.4% of the population; however, BDD typically goes unrecognized in clinical settings. In this chapter we discuss demographic and clinical features of BDD, prevalence, and morbidity. In addition, we discuss BDD’s relationship to obsessive compulsive disorder, hypochondriasis, and psychotic disorders.
