UNDERGRADUATE SYLLABUS SUBJECT: Psychology PAPER: Abnormal Psychology TOPIC: Dissociative and Somatoform Disorders LESSON: Dissociative Disorders – Part 2 Dissociative Disorders – Part-2 Dissociative Identity Disorder Perhaps the most bizarre of the dissociative disorders is dissociative identity disorder (DID), formerly known as multiple personality disorder. In this dramatic disorder pattern, the personality breaks up into 2 or more distinct identities or personality states, each well integrated and well developed, which then take turns controlling the person's behavior. Amnesia is part of the pattern. At least one of the different identities is amnesic for the experiences of the other or others (Dorahy, 2001). Each identity may appear to have a different personal history, self image and name, though there are some identities that are only partially distinct and independent from other identities. The first case of DID to receive extensive professional attention-the case of Miss Beauchamp, who may have had as many as 17 identities-was reported by Morton Prince in 1905. Ever since, this disorder has held a certain fascination for the public, as shown by the immense popularity of Thigpen and Cleckley's The Three Faces of Eve (1957), both book and movie, and by the best-seller Sybil (Schreiber, 1974), about a girl with 16 personality states. In Dissociative Identity Disorder, a distinction is usually made between the host, the personality state, corresponding to who the person was before the onset of the disorder, and the alters, the later-developing identities. The personality that is most frequently encountered and carries the person’s real name is the host identity. The alter identities may differ in striking ways involving gender, age, handedness, handwriting, and so on. For example one alter may be carefree, funloving and sexually provocative and another alter quiet, studious, serious, and prudish. Needs and behaviors inhibited in the host identity are usually liberally displayed by one or more alter identities. There are many different configurations of host and alters (Putnam, 1997). In the simplest pattern, called alternating personality, 2 identities take turns controlling behavior, each having amnesia for the thoughts and actions of the other. In a slightly more complex pattern, the alter knows about the host, but the host doesn't know about the alter (Dorahy, 2001). While the host is directing the person's behavior the alter, fully aware of the thoughts and actions of the host, continues to operate covertly and to make its presence felt now and then. In such cases, the alter is said to be coconscious (Prince, 1905) with the host. When the coconscious alters finally surfaces, it can discuss in detail the interesting problems of the host. Meanwhile, the host only gradually becomes aware of the existence. of the alter, usually by encountering the evidence of his or her activities. In one case (Osgood, Luria, Jeans, Smith., 1976), the host, “Gina," first learned of the existence of her alter, “Mary Sunshine," when she began waking up in the morning to find cups with leftover hot chocolate in the kitchen sink. Gina did not drink hot chocolate. But even, this is an atypically simple pattern. Most DID patients have far more than one alter-surveys have even found an average of 13 per patient (Putnam, 1997; Putnam, Guroff, Silberman, Barban, & Post., 1986)and the host and alters often have complex patterns of coconsciousness. One identity may know about another, but not about a third; that third identity may be in league with a fourth and a fifth, but not with the sixth and seventh; and so on. The transition from one personality to another is called a switch. Usually the switch is instantaneous (unlike the dramatic effect shown in movies). Physical transformations may occur during switches ex: posture, facial expressions, patterns of facial wrinkling, and even physical disabilities may emerge. In one study, changes in handedness occurred in 37% of the cases. (Putnam, Guroff, Silberman, & Barban, & Post., 1986). The presence of more than one identity and significant amnesia for what the alter identities have experienced are not the only symptoms of Dissociative Identity Disorder. Other symptoms include depression, self-mutilation, and frequent suicidal ideation and attempts. People with DID often show moodiness and erratic behaviour, headaches, hallucinations, substance abuse, post-traumatic symptoms, and other amnesic and fugue symptoms. (APA, 2000; Maldonado, Butler, & Spiegel., 2002). Types of Personalities Many cases of DID involve identities that are 'polar opposites: one conformist, reserved, "nice" personality and one rebellious, aggressive, "naughty" personality, In surveys of dissociative identity patients by two teams of researchers, at least 50 percent of the patients reported drug abuse by an alternate identity; 20 percent claimed that an alternate identity had been involved in a sexual assault on another person; and 29 percent reported that one of their alternates was homicidal (Putnam, Guroff, Silberman, & Barban, & Post ., 1986; Ross, Miller, Reagor, et al., 1990). Dissociative identity patients may do violence to themselves when one identity tries to kill another. Such "internal homicide" attempts were reported by more than half the people. But "good versus bad" is not the only pattern. It is possible that, one identity encapsulates a traumatic memory, while another reflects a former abuser. In other cases, the personality states' may divide up the emotional life, one dealing with anger, another handling sadness, and so on. The disorder usually starts in childhood, although most patients are in their twenties or thirties at the time of their diagnosis (Ross, 1997). Approximately three to nine times more females than males are diagnosed as having the disorder, and females tend to have a larger number of alters than do males (APA, 2000). Causes: In the Putnam survey, 97 out of 100 patients reported some significant trauma in childhood. The most common was sexual abuse, reported by 83 percent of the patients; in 68 percent of the patients, this sexual abuse involved incest. Three fourths of the patients also claimed to have suffered repeated physical abuse in childhood, and almost half reported having witnessed a violent death, usually of a parent or sibling, during their early years. The nearly unanimous testimonies of abuse suggest that dissociative identity disorder may be a stratagem that terrified children use to distance themselves from the realities of their lives (Atchison & McFarlane, 1994). In support of this view, most patients report that the disorder began in childhood, at a time of severe trauma. (In the Putnam survey, 89 percent reported onset before the age of 12). On the other hand, there is the criticism that rejects many cases as false cases. Increasingly over years, even firm defenders of the DID diagnosis have become more concerned about false cases. For example, Ross (1997) estimates that a quarter of the DID cases in the dissociative disorders unit that he directs are either faked or iatrogenic (induced by therapy). That the central feature of DID, the presentation of multiple identities, is usually not observable before treatment and that this essential feature becomes visible during treatment are major reasons why some critics have argued that DID is, at least in part, induced by therapy (Spanos, 1996; Lilienfeld, Lynn, Kirsch, et al., 1999). According to auto hypnotic model, people who are suggestible may be able to use dissociation as a defense against extreme trauma (Putnam, 1991). Indeed, a survey of boardcertified American psychiatrists found little consensus regarding the diagnostic status and scientist validity of DID (Pope, Oliva, Hudson, et al., 1999). Dissociative Disorders: Theory and Therapy 1. The Psychodynamic Perspective: Defense Against Anxiety Dissociation as Defense Freud, believed that when many basic human wishes were in direct conflict with either reality or the superego, the result of this conflict is painful anxiety. To protect the mind against the anxiety, the ego represses the wish and mounts defenses against it. The dissociative disorders are simply extreme and maladaptive defenses. Dissociative amnesia, for example, is regarded by Freudian theorists as a simple case of repression. Fugue and dissociative identity disorder are more complicated, in that the person also acts out the repressed wish directly or symbolically. Thus the fugue patient goes off and has adventures. The person with dissociative identity disorder becomes a different, "forbidden" self-while the ego maintains amnesia for the episode, thus protecting the mind against the strictures of the superego. Treating Dissociation Psychodynamic therapy is the most common treatment for the dissociative disorders. When trauma is involved, or thought to be involved, the treatment generally proceeds in three stages. Stage 1 involves settling the patient down: establishing an atmosphere of trust and helping the patient to gain some mastery over the dissociative symptoms. Then, in stage 2, the traumatic memory is recovered and grieved over. Stage 3 is devoted to the reintegration of the traumatic memory, so that the patient no longer has to use dissociation to wall it off (Herman, 1992; Kluft, 1999). In amnesia, fugue, and DID, the traditional method of bringing forth the lost material has been hypnosis. (Barbiturates and benzodiazepines may achieve the same effect). A disadvantage of hypnosis is that in some cases it seems to bring on or exacerbate dissociative symptoms (Destun & Kuiper, 1996; Powell & Gee, 1999). Another concern is that the memory retrieval may be re-traumatizing particularly when it takes the form of abreaction (the intense re-experiencing of the event) and unnecessarily prolonged, plunging the patient again and again into a state of emotional crisis. Some therapists now avoid abreactions (Ross, 1997). Kluft (1999) has proposed a technique called fractionated abreaction, in which the memory is retrieved only gradually, in small parts, while the therapist encourages mastery and discourages surrender to emotion. 2. The Behavioral Perspective: Dissociation as a Social Rule Learning to Dissociate The behaviorists have conceptualized the dissociative disorders as a form of learned coping response, with the production of symptoms in order to obtain rewards or relief from stress. According to the behaviorists, the dissociative disorders, like many other psychological disorders, are the result of a person's adopting a social role that is reinforced by its consequences (Seltzer, 1994). In amnesia, fugue, and dissociative identity disorder, the rewarding consequence is protection from stressful events. It is important for the student here to note the similarity between this interpretation and the psychodynamic view. In both cases, the focus is on motivation, and the motivation is escape. The difference is that in the psychodynamic view the process is unconscious, whereas in the behavioral view dissociative behavior is maintained by reinforcement. Non-reinforcement According to behavioral and socio-cultural theory, the way to treat dissociative symptoms is to stop reinforcing them (Spanos, 1996). 3. The Cognitive Perspective: Memory Dysfunction Cognitive theorists view the dissociative syndromes as fundamentally disorders of memory (Dorahy, 2001). In each case, what has been dissociated is all or part of the patient's autobiography. As we have seen in the preceding sections, the patient's skills (procedural memory) and general knowledge (semantic memory) are usually intact. What is partially impaired is the patient's episodic memory or record of personal experience. Patients may still show evidence that they have implicit memory of their past. What they don't have is explicit memory for the dissociated material, the ability to retrieve it into consciousness. Improving Memory Retrieval To date, there has been little work on cognitive therapy for dissociative disorders. Nevertheless, many therapists use cognitive techniques in treating patients with dissociative disorders (Brand, 2001). For example, in the case of Jane Doewhere the personal details were not remembered, the therapist appealed to her implicit memory by asking her to punch in telephone numbers at random. The method worked and when the numbers were punched at random, there was a number where her family members responded. 4. Integrated approach Some treatments for DID, such as tactical-integration therapy, combine cognitivebehavioral and psychodynamic approaches (Fine, 1999). In this therapy, the first stage of treatment focuses on the cognitive distortions and dysfunctional beliefs arising from past traumas among the various alters. These trauma-based cognitive biases are challenged with typical cognitive techniques, such as hypothesis testing and reattribution training. The second stage is more psychodynamic and involves fractionated abreaction and mastery of emotion. 5. The Neuroscience Perspective: Brain Dysfunction According to neuroscience researchers, some so called dissociative disorders may be neurological disorders. According to one theory (Sivec &Lynn, 1995), the dissociative syndromes may be a by-product of undiagnosed epilepsy. This theory may apply to certain dissociative conditions, but it is unlikely to explain DID, in which the symptoms are far more elaborate than the dissociative experiences reported by epileptic patients. A second hypothesis has to do with the hippocampus, a part of the limbic system. When a memory needs to be retrieved, it is apparently the hippocampus that brings the memory elements back together and integrates them. But stress can derail this process. In autopsies of monkeys and in MRI scans of human beings, it has been shown that stress can lead to structural changes in the hippocampus, including the atrophy of cells. Stress can also trigger the release of neurotransmitters that are highly concentrated in the hippocampus-a process that is thought to interfere with the encoding and retrieval of memories. Finally, it has been suggested that, at least in depersonalization disorder, there may be some abnormality in serotonin functioning. 6. Drug Treatment Little in the way of biological treatment has been developed for the dissociative disorders. The barbiturate sodium amytal or the benzodiazepine lorazepam can be used as alternatives to hypnosis to aid in the recovery of memories, although the reliability of such memories is no better than with hypnosis. As researchers gain more knowledge about stress-induced changes in memory function, it is hoped that they will be able to develop medications for the dissociative disorders.
