The relationship between characteristics of sexual abuse and dissociative experiences.

Childhood sexual abuse has been associated with adult dissociative symptomatology. The purpose of this study was to examine the relationship between specific characteristics of sexual abuse and dissociative experiences in adulthood. Fifty-six female inpatients with a history of physical abuse and severe sexual abuse reported on their history of abuse and dissociative experiences. A logistic regression that controlled for physical revictimization showed that sexual abuse by a greater number of different sex abuse offenders was significantly related to an elevated level of dissociation. In exploring how many sex abuse offenders are associated with dissociative experiences, a logistic regression revealed a significant relationship between four or more sex abuse offenders and greater dissociative symptomatology. The reported age of onset of the sexual abuse was not a significant predictor of dissociation when sexual revictimization was included in the analysis. These findings suggest that severely traumatized patients with a history of multiple sex abuse offenders are highly likely to use dissociation as a primary psychological defense. The implications of the study are discussed.
