The average age at onset of body dysmorphic disorder was 15 years, and the average duration was 18 years. The 17 men and 13 women reported a lifetime average of four bodily preoccupations, most commonly "defects" of the hair, nose, and skin. The patients (including 12 whose preoccupation was of probable delusional intensity) were assessed with a semistructured interview and the Structural Clinical Interview for DSM-III-R, and their family histories were obtained. The authors investigated the demographics, phenomenology, course, associated psychopathology, family history, and response to treatment in a series of 30 patients with the disorder. Body dysmorphic disorder, preoccupation with an imagined defect in appearance, is included in DSM-III-R but has received little empirical study.
