Complex Dissociative Disorders Terminology: A Basic Primer
[Large text: DID Terminology: A Basic Primer]
Here are some common terms you may see when researching complex dissociative disorders!
[Large Text: Basic Terms]
Dissociation - An internal feeling of disconnect between one's body, history, thoughts, emotions, memories, acts, and/or environment. Not everyone who experiences dissociation has a dissociative disorder. Dissociation is a common coping mechanism in times of stress.
Alter - A dissociated part of a personality that failed to integrate into the self due to trauma. These parts may have their own age, gender, needs, wants, sexuality, species, memories, actions, urges, opinions, skills, abilities, etc.
Fragment - An alter who is not fully “fleshed out” or differentiated. They may have a single function, emotion, or memory.
System - The entire collection of alters in one body
Front - The alter who is “in front” or “fronting” is aware of the outside world, and controlling the body.
Switch - “to switch” is to change what alter is fronting (controlling the body). This can be slow or fast, planned or unplanned, accidental or intentionality.
Co-consciousness (co-con) - When two or more alters are aware of the outside world they are co-conscious.
Passive Influence - When an alter who is not currently fronting affects the fronting alter. This can be in the form of memories, thoughts, emotions, desires, preferences, actions, etc.
Splitting - To split is to create a new alter
Amnesia - partial or complete loss of memory (not exclusive to CDD)
Complex Dissociative Disorder (CDD) - An umbrella term for all dissociative disorders that cause systems. This list includes Dissociative Identity Disorder (DID), Other Specified Dissociative Disorder Type 1 (OSDD-1), Unspecified Dissociative Disorder (UDD), and Partial Dissociative Identity Disorder (P-DID).
Dissociative Disorder - To quote https://did-research.org/ “a disorder characterized by a separation of consciousness from emotion, sensation, memory, personal history, sense of self, or sense of reality.”
Dissociative Identity Disorder (DID) - DID is characterised by two or more dissociative self-states "Alters" that are linked to some degree of amnesia and are capable of assuming executive control.
Other Specified Dissociative Disorder Type 1 (OSDD-1) - OSDD-1 is a disorder that is very similar to DID but lacks fully differentiated selves (type 1a) or amnesia (type 1b). OSDD in general is a category of dissociative disorders that while not fitting the criteria for any other dissociative disorder, can still be specified.
Unspecified Dissociative Disorder (UDD) - A category of disorders that can not be labeled, or are unable to be fully understood. This diagnosis is most often applied in crises or emergencies.
Partial Dissociative Identity Disorder (P-DID) - As outlined by the International Classification of Diseases is a condition similar to DID where “One personality state is dominant and normally functions in daily life, but is intruded upon by one or more non-dominant personality states (dissociative intrusions).” Essentially one alter is always in front, but they regularly experience passive influence or co-consciousness.
Multiple Personality Disorder (MPD) - This is a former term for DID. The name was changed because DID is not a personality disorder, it’s a dissociative disorder. Many people today find this term insensitive, outdated, and offensive, although some systems may choose to self-identify with the term.
The Theory of Structural Dissociation (TOSD)
[Large Text: The Theory of Structural Dissociation (TOSD)]
This is the current understanding of how dissociative disorders as well as other disorders caused by trauma are formed and function. To quote https://did-research.org/ “this theory centers around an inability to integrate traumatic memories and materials into one’s primary personality, sense of self, and self history that results in an overall inability to integrate parts.”
