Final answer:
More than 90% of people with dissociative identity disorder have a history of childhood abuse, highlighting a significant association between early severe trauma and the development of DID.
Step-by-step explanation:
According to research studies, more than 90% of people diagnosed with dissociative identity disorder (DID) have histories of childhood physical and sexual abuse. This is a substantial majority, indicating a strong correlation between the experience of severe abuse in childhood and the development of DID.
The prevalence of childhood abuse, in general, is very high, with neglect being the most common form, followed by physical abuse, sexual abuse, psychological maltreatment, and medical neglect. However, when specifically examining DID, the relationship between childhood trauma, particularly severe forms of abuse, and this mental health disorder becomes apparent.
