Dissociation debates: everything you know is wrong.

Controversy about dissociation and the dissociative disorders (DD) has existed since the beginning of modern psychiatry and psychology. Even among professionals, beliefs about dissociation/DD often are not based on the scientific literature. Multiple lines of evidence support a powerful relationship between dissociation/DD and psychological trauma, especially cumulative and/or early life trauma. Skeptics counter that dissociation produces fantasies of trauma, and that DD are artefactual conditions produced by iatrogenesis and/or socio-cultural factors. Almost no research or clinical data support this view. DD are common in general and clinical populations and represent a major underserved population with a substantial risk for suicidal and self-destructive behavior. Prospective treatment outcome studies of severely ill DD patients show significant improvement in symptoms including suicidal/self-destructive behaviors, with reductions in treatment cost. A major public health effort is needed to raise awareness about dissociation/DD, including educational efforts in all mental health training programs and increased funding for research.
