Basis of guidelines
There are no National Institute of Health and Clinical Excellence (NICE) guidelines for the treatment of dissociative identity disorder (DID) and so the best available treatment guidelines are those supplied by the International Society for the Study of Trauma and Dissociation (ISSTD). They can be found here.
The view of many people with regard to dissociative identity disorder has been influenced by Hollywood representations such as in the book and film Sybil. Many people also believe that it is a rare condition. But an increasing body of research, literature and clinical material is providing a new and more accurate representation of dissociative identity disorder.
Dissociative disorders are characterised by ‘a disruption in the usually integrated functions of consciousness, memory, identity or perception of the environment’. So for example memories and feelings may not go together – memories may be recalled with no accompanying affect or emotions, or there may be overwhelming feelings with no conscious memory of their cause. There is also often a lack of a coherent sense of autobiography, and this itself leads to problems with a sense of identity – ‘Who am I?’ and ‘What has happened in my life?’ This all results from dissociation acting as a creative survival mechanism in the face of overwhelming trauma, whereby the mind shields itself by segregating the experience, or splitting it off into its constituent parts rather than experiencing it as what would be an unendurable ‘whole’.
There are a range of dissociative disorders on a spectrum of severity, and this spectrum is usually correlated to how extreme and chronic the trauma experienced in early childhood was. The least extreme on the spectrum is post-
The essence of dissociative identity disorder is ‘dissociating’ or ‘splitting off’ from an experience – and then in time, splitting off from the ‘parts’ of the self that hold those experiences – in order to survive otherwise unendurable trauma. It is a creative coping mechanism, not a ‘dysfunction’. However, it becomes dysfunctional when the environment is no longer traumatic and yet the person, and all the ‘dissociated identities’ of that person, still act and live as if it is.
In practice, the vast majority of people with dissociative identity disorder do not obviously present as if they have ‘multiple personalities’. Instead they present with a number of both dissociative and post-

Many experts in dissociative disorders believe that alternate identities (sometimes known as ‘alters’ or ‘parts’ etc) result from overwhelming traumatic experiences in early childhood, in the context of disturbed caretaker-
Dissociative identity disorder is normally caused by severe and chronic childhood trauma, which may include physical and sexual abuse and/or neglect, episodes of extreme terror, and/or repeated medical trauma. Disorganised attachment in one or both parents is also a contributory factor. According to a recent study by Brand et al, 86 per cent of the sample of dissociative identity disorder patients reported a history of sexual abuse. Many clinicians position DID in a post-
People with dissociative identity disorder often spend many years in the mental health system, and it is often misdiagnosed as schizophrenia or other psychotic disorders, affective disorders, substance abuse disorders, or a personality disorder (most commonly borderline personality disorder). There are a number of well-
The treatment of choice for dissociative identity disorder is long-
The consensus of experts is that phase-
- Establishing safety, stabilisation and symptom reduction;
- Working through and integrating traumatic memories;
- Integration and rehabilitation.
In reality, there is unlikely to be a linear progression through these three stages: more commonly the work will spiral through each phase, with a frequent need to return to stabilisation work during the middle and later stages. As well as addressing dissociative symptoms, and working through and integrating the underlying trauma, a third area of treatment is that of ‘attachment’, with the vast majority of dissociative identity disorder clients presenting with disorganised attachment patterns.
Issues for the therapist
The extreme and chronic nature of the trauma suffered by many dissociative identity disorder clients can lead to complex and changeable transference and countertransference responses in the therapy. Extreme care must be given to the issue of boundaries: the history of many dissociative identity disorder clients is steeped in boundary violations and so there is significant potential for re-
It is the quality of the relationship between therapist and client which is the best predictor of therapeutic success, and so a warm, empathic, consistent, engaged therapist who is willing to be flexible and work long-
Working with ‘alter personalities’
A client with dissociative identity disorder, at some point during therapy, will invariably present with their ‘alternate personalities’, otherwise known as ‘alters’, ‘parts’ etc. These may present as having different ages, a different gender, different characteristics and often different levels of awareness of their autobiography. Some will be aware of or ‘co-
It is important to bear in mind that the parts ‘are not actually separate identities or personalities in one body, but rather parts of a single individual that are not yet functioning together in a smooth, coordinated, and flexible way’. The ultimate work of therapy is to facilitate an increased coordination between these parts, so that they can indeed function together and perhaps even merge or ‘fuse’. By working on increased communication and cooperation between parts, often there is a corresponding increase in levels of co-
There have been some helpful ways of understanding and classifying these different ‘parts’ in terms of the role and function they play in the person’s life as a whole. Van der Hart et al propose in their theory of ‘structural dissociation’ a basic division between the Apparently Normal Personalities (ANPs) and the Emotional Personalities (EPs) – the former tend to be preoccupied with getting on with life and manage by blocking out memories and experiences connected to the past traumatic events, while the EPs are ‘stuck’ in those experiences and experience them as now rather than as past. Much of the therapy in working with dissociative identity disorder is concerned with resolving conflicts between this basic split, and in resolving a further level of conflicts between different EPs’ favoured ‘survival response’ such as fight, flight, freeze or submit. The entire personality is structured around the causative trauma, either in experiencing it (the EPs) or avoiding it (the ANPs). The theory of structural dissociation can be very helpful in coming to find helpful ways of working with all of the different parts of the personality.
There has been much debate and controversy about whether engaging with ‘alternate personalities’ is therapeutic or not, but the ISSTD guidelines1 do advise engaging with all parts of a person’s personality in a non-
