Clinical features, cognitive biases, and treatment of body dysmorphic disorder.

In the past two decades, research advances have enhanced our understanding of the clinical features, cognitive biases, and treatment of body dysmorphic disorder (BDD). In this review, we critically examine the current state of the evidence on the proposed cognitive and emotional processing mechanisms of BDD. We describe how major findings in these areas made unique contributions to the development of an empirically informed cognitive-behavioral model of BDD, which in turn facilitated the translation of research to treatment strategies. Finally, we outline important areas of future research.
