Dissociative Identity Disorder (DID)

Dissociative Identity Disorder (DID) is also known by it's former label of Multiple Personality Disorder (MPD) in the American Psychiatric Association’s Diagnostic & Statistical Manual (DSM-IV)

Dissociative Identity Disorder is the condition in which a person displays more than one unique identity or personality, each with its own pattern of behaviors.

The diagnosis of Dissociative Identity Disorder requires that at least two personalities routinely take control of a person's behavior. This is accompanied by an associated memory loss that goes beyond normal forgetfulness. Each personality is unaware, or unfamiliar with the others.

Additionally, for a valid DID diagnosis, the symptoms cannot be explained by substance abuse or another medical condition.

Earlier versions of the DSM named the condition Multiple personality disorder (MPD) and the term is still commonly used.

DID is a controversial diagnosis. There is argument about its validity, existence, causes, and epidemiology.

DID Characteristics - The DSM-IV Criteria

Text in Bold Italics is quoted from the American Psychiatric Association’s Diagnostic & Statistical Manual (DSM-IV)

Diagnostic criteria for 300.14 Dissociative Identity Disorder (formerly known as Multiple Personality Disorder)

A. The presence of two or more distinct identities or personality states (each with its own relatively enduring pattern of perceiving, relating to, and thinking about the environment and self). 

B. At least two of these identities or personality states recurrently take control of the person's behavior. 

C. Inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness. 

D. The disturbance is not due to the direct physiological effects of a substance (e.g., blackouts or chaotic behavior during Alcohol Intoxication) or a general medical condition (e.g., complex partial seizures). Note: In children, the symptoms are not attributable to imaginary playmates or other fantasy play.

Understanding the clinical criteria for Dissociative Identity Disorder is helpful but learning how to cope with having a loved-one who suffers from DID is quite different and is not covered in any psychological manual.

One of the most effective ways we have found to deal with that is to get support from people who understand what it feels like to live with someone who routinely disassociates, rewrites history, acts destructively and illogically, takes little or no responsibility for their own behaviors.

We have learned together how to cope and stop the abusive cycle. The first step is to visit our message board.

Out of the Storm - New CPTSD Support Site

August 25, 2014 - OOTF announce an exciting new development - it's called Out of the Storm - a support site specifically designed for people who suffer from CPTSD - Complex Post Traumatic Stress Disorder. At OOTF we have often welcomed members who are dealing with CPTSD as a consequence of having been in a relationship with someone who suffers from a personality disorder. Nevertheless, for a long time we have recognized that CPTSD sufferers have a distinct and unique set of concerns and issues.

Out of the Storm is now online at CPTSD.org

New "Future Goals" Forum

Nov 9, 2013 - OOTF has just launched a new "Future Goals" forum. This forum is a safe place to store your goals of what you would like to achieve. Setting goals can help us move forward, and give us something to focus on while we are working our way through day to day issues. Goals can change, be amended or added to over time as we either achieve them, or determine new goals as our lives unfold.
