In this paper I propose the existence of two distinct presentations of DID, a Stable and an Active one. While people with Stable DID struggle with their traumatic past, with triggers that re-evoke that past and with the problems of daily functioning with severe dissociation, people with Active DID are, in addition, also engaged in a life of current, on-going involvement in abusive relationships, and do not respond to treatment in the same way as other DID patients. The paper observes these two proposed DID presentations in the context of other trauma-based disorders, through the lens of their attachment relationship. It proposes that the type, intensity and frequency of relational trauma shape—and can thus predict—the resulting mental disorder. - Through the lens of attachment relationship: Stable DID, Active DID and other trauma-based mental disorders
