The authors cite a report finding that patients with a history of trauma had higher scores on the Dissociative Questionnaire, particularly on the subscale for amnesia, than patients without a history of abuse. They describe the variables that may mediate the link between abuse and dissociative symptoms. The presence of comorbid psychiatric disorders is attributed to impulsive dyscontrol. The authors present the results of a study of stealing behavior, which found that 47% of 73 patients had stolen. In a study of self-injurious behavior, almost half of 94 female patients had at least one form of self-injury during the past year.
