my understanding and experience with integration is -

once full integration has happened nothing can cause the person to dissociate into alters ever again... the reasoning for this is that mental health communities here where I live and work and I believe alters with DID are created in childhood, that only children going through extreme trauma can through the use of dissociation, dissociate to the point that their minds create alternate personalities to hold that which they cannot handle. Once full integration happens thats it. the alters have been completely merged back with the host to form one whole person again. the person is now just like any other normal person without alters because though they know they had alters everything the alters were is now that person. example Rainy was my alter that was depressed and cried. after integration though I will always know there was rainy who was depressed and cried, rainy is now me, I can cry now and I go through times when I am depressed, I can now feel all the emotions and express all the emotions that once was rainy. shes still here with me but in a different way..shes here as in I now do, remember and think the way she did, but its different because there is no other personality called rainy taking over control of the body acting out. thats no longer possible because I am rainy and she is me we are one and the same person now.

that doesnt mean I wont have personality problems where I end up with another alter, DID is not the only mental disorder that has the symptom of percieving one self as two different people..one good the other bad or evil, for example people with Dissociative Disorders Not Otherwise specified may in some locations have one alternate personality, some people with schizophrenia type mental disorders have an alternate personality, some people with bipolar disorder perceive their self as two different people one good and the other one bad, people diagnosed with ego states have a type of alternate personalities called ego states that are similar to that of having DID. this is just a few examples...

unless there are two alternate personalities taking over control with their own way of being here where I live and work I will never again carry the present diagnosis of having DID or havig DID like alters. who know some day gosh forbid we find out theres a previously undiagnosed, unknown alter that was never integrated. legally here where I live and work I would not be able to carry the DID diagnosis because that requires two or more alters but I may be called - split personality disordered or any of the above depending upon the circumstances with which this alter appeared, came into being, got left behind what ever..

other locations, cultures may believe otherwise but this is what is believed among the mental health community here where I live and work.
