Have you heard of partial did/ p-did?
yes i have! it's basically the ICD-11's version of OSDD-1
"Partial dissociative identity disorder is characterised by disruption of identity in which there are two or more distinct personality states (dissociative identities) associated with marked discontinuities in the sense of self and agency. Each personality state includes its own pattern of experiencing, perceiving, conceiving, and relating to self, the body, and the environment. 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). These intrusions may be cognitive, affective, perceptual, motor, or behavioural. They are experienced as interfering with the functioning of the dominant personality state and are typically aversive. The non-dominant personality states do not recurrently take executive control of the individual’s consciousness and functioning, but there may be occasional, limited and transient episodes in which a distinct personality state assumes executive control to engage in circumscribed behaviours, such as in response to extreme emotional states or during episodes of self-harm or the reenactment of traumatic memories."
TL;DR: it's DID but alters don't normally front except for high stress situations (e.g. being triggered). Amnesia doesn't usually occur except for extremely stressful situations or self-harm.
Difference between P-DID & DID: no amnesia, no fronting except in stressful times, alters are experienced internally, alters are more limited (less elaborated & separate) and are more like fragments and/or Emotional Parts.
Difference between P-DID & OSDD-1: no amnesia (1a), less elaborated alters (1b), I suppose it's more like OSDD-1a without the amnesia (OSDD-1c?). here's a post critiquing P-DID as it relates to OSDD-1.
