Yes, in Dissociative Identity Disorder (DID), the "host" can indeed function as a protector for the other alters (also known as parts, identities, or personalities). The host is the term used to refer to the identity state that is most often present or in control of the individual's consciousness, and it is the identity that is most familiar to the outside world.
In DID, the presence of different alters is a result of the mind's way of coping with severe and repeated trauma. Each alter may have unique roles, functions, and coping mechanisms. Some alters may be created to hold and manage traumatic memories, while others might serve as protectors whose primary role is to shield the system (the collection of alters) from further harm.
The host can function as a protector in several ways:
Gatekeeper: The host may take on the role of a gatekeeper, controlling when and how other alters can come forward and interact with the external world. This helps in managing the switching between alters and maintaining some level of stability and continuity in the person's life.
Crisis Management: When the system faces a crisis or a triggering situation, the host may step in to manage the situation and prevent it from overwhelming other vulnerable alters.
Communication Facilitator: The host might be the one most skilled at communicating with therapists or support systems, which can aid in the therapeutic process and seeking help when needed.
Maintaining Daily Functioning: As the most familiar identity to the outside world, the host often takes on the responsibility of handling day-to-day tasks and interactions in the person's life, contributing to overall functioning and stability.
It's important to note that the roles and functions of alters, including the host, can vary widely from one person with DID to another. Additionally, the host may not always be aware of the presence of other alters or the full extent of their roles, especially if there is significant amnesia between alters.
Therapy for DID aims to help individuals understand their alters, their roles, and the relationships between them. The goal is to promote cooperation and communication among alters, including the host, to foster internal harmony and improve overall well-being. With the guidance of a skilled therapist experienced in treating dissociative disorders, individuals with DID can work towards achieving integration and a more cohesive sense of self.
