Chronic trauma (according to the meaning I propose) that occurs early in life has profound effects on personality development and can lead to the development of dissociative identity disorder (DID), other dissociative disorders, personality disorders, psychotic thinking, and a host of symptoms such as anxiety, depression, eating disorders, and substance abuse. In my view, DID is simply an extreme version of the dissociative structure of the psyche that characterizes us all.
