OSDD, or Other Specified Dissociative Disorder (also known as DDNOS), is a group of dissociative trauma disorders that are similar to existing dissociative disorders, but do not fit the full diagnostic criteria. There are four types.
OSDD-1: For when someone appears to have DID, but either does not have distinct alters or does not experience amnesia between alters (known as OSDD-1a and 1b, respectively).
OSDD-2: For when someone experiences a dissociative identity disturbance due to brainwashing, torture, being in a cult, or other “prolonged and intense coercive persuasion.”
OSDD-3: For when experiences acute dissociative reactions to stressful events, typically for less than a month.

OSDD-4: For when someone experiences an unexpected dissociative trance.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
