Diagnosing dissociative disorders in The Netherlands: a pilot study with the Structured Clinical Interview for DSM-III-R Dissociative Disorders.

OBJECTIVE: To improve the ability to diagnose dissociative disorders in The Netherlands, the authors conducted a study using a Dutch version of the Structured Clinical Interview for DSM-III-R Dissociative Disorders (SCID-D) with additional questions on childhood trauma and symptoms of borderline and histrionic personality disorders. METHOD: All interviews were audiotaped or videotaped and rated by two investigators separately. Forty-four patients (42 women and two men) participated in the study. Most of the patients had been referred for evaluation of dissociative symptoms; five had participated in a nationwide survey on incest. None of the patients had ever received a diagnosis of a dissociative disorder, and none had evidence of organic brain syndrome or mental retardation. All patients were in active treatment; 23 were being treated in an outpatient psychiatric service, 13 in an inpatient psychiatric service, and eight in private practice. Thirty-two patients had been psychiatric inpatients at least once. RESULTS: Four diagnostic groups of patients were identified: two with dissociative disorders (12 patients with multiple personality disorder and 11 with dissociative disorder not otherwise specified), one with DSM-III-R personality disorders (11 patients), and one without dissociative or personality disorders (10 patients). CONCLUSIONS: Dissociative disorders are clearly not only an American phenomenon. The diagnosis can be made outside of the United States if the symptoms are sought. The SCID-D proved to be a promising instrument.

The use of hypnosis with dissociative disorders.

The dissociative disorders are characterized by difficulties in the integration of memory and/or identity. Typically this is manifested by amnesia and either the development of alternate identities or an estrangement from one's own identity. Spontaneous and self-generated dissociative states and phenomena sharing much in common with those that can be induced with hypnosis are thought to play a major role in their development, symptomatology, and perpetuation. Medical heterohypnosis offers a powerful tool to reestablish a functional continuity of memory and identity in many such cases. The application of hypnotic interventions in the treatment of such conditions will be discussed, explored, and illustrated with clinical vignettes.

Disintegrated experience: the dissociative disorders revisited.

We present proposed changes to the dissociative disorders section of the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders and review the concept of pathological and nonpathological dissociation, including empirical findings on the relations between trauma and dissociative phenomenology and between dissociation and hypnosis. The most important proposals include the creation of two new diagnostic entities, brief reactive dissociative disorder and transient dissociative disturbance, and the readoption of the criterion of amnesia for a multiple personality disorder diagnosis. We conclude that further work on dissociative processes will provide an important link between clinical and experimental approaches to human cognition, emotion, and personality.

Detection of dissociative disorders in psychiatric patients by a screening instrument and a structured diagnostic interview.

OBJECTIVE AND METHOD: Diagnosis and treatment of the dissociative disorders may be delayed for many years because of difficulties in detecting patients at high risk for dissociative disorders. This study investigates the utility of the Dissociative Experiences Scale (DES), a self-report instrument for dissociative experiences, in detecting patients at high risk for dissociative disorders. The clinician-administered Structured Clinical Interview for DSM-III-R Dissociative Disorders (SCID-D) was used as the diagnostic standard, and 36 outpatients with mixed diagnoses and nine normal subjects were evaluated for the presence and absence of a dissociative disorder. DES scores were then compared. RESULTS: Results indicate that a DES cutoff score of 15-20 yields good to excellent sensitivity and specificity as a screening instrument. However, for higher cutoff points the sensitivity can be much lower. CONCLUSIONS: Thus, although the DES can be used to identify some high-risk patients, they should be further evaluated with such diagnostic instruments as the SCID-D or by in-depth clinical follow-up.

Psychotherapy of the survivor of incest with a dissociative disorder.

The treatment of the survivor of incest who suffers from a dissociative disorder is probably somewhat more difficult than that of other survivors of incest because for these others the material is more readily available. Also the patient with DD was probably more severely abused or the dissociative defense would not have been needed. This too makes therapy difficult, especially in that most necessary step: the development of trust and rapport. Despite these problems, there is a very good chance for a successful therapy that will bring the dissociated material back into the main stream of consciousness with a "here and now" appropriate perspective. This can be accomplished through proper diagnosis, good theoretics grounding, and therapy including psychotherapy with appropriate limit setting and the judicious use of medication. This article presents a summary of the BASK model of dissociation and two other models and gives ideas on how these models may be applied to the understanding of the etiology of dissociative disorders and their treatment. Case examples are used to illustrate successful treatment. Although treatment of incest survivors with dissociative disorders is difficult, success can be anticipated, and the rewards to the patient and the satisfaction for the therapist are great.

The use of electroconvulsive therapy in patients with dissociative disorders.

The psychiatric literature generally discourages the use of electroconvulsive therapy (ECT) to treat depression in dissociative disorder patients, but contains little data on outcome. This prospective study of ECT in three dissociative disorder patients demonstrates that ECT is indicated for severe treatment-resistant depression in such patients. Their Hamilton Depression Scale scores fell by 50%, they were remarkably clinically improved, and they maintained their gains for at least 4 months. The ECT proved helpful when depression was felt by most of the active alters rather than just by one depressed personality. Mini-Mental State Examination scores and clinical observation revealed no unusual confusion or side effects from ECT. These patients' dissociated condition was not altered by ECT, which indicates that ECT neither treats nor impairs treatment of dissociation. Electroconvulsive therapy can be helpful in the overall treatment of dissociative disorders by alleviating severe depressions which block utilization of psychotherapy.

The Structured Clinical Interview for DSM-III-R Dissociative Disorders: preliminary report on a new diagnostic instrument.

The authors describe the Structured Clinical Interview for DSM-III-R Dissociative Disorders (SCID-D), which investigates five groups of dissociative symptoms (amnesia, depersonalization, derealization, identity confusion, and identity alteration) and systematically rates both the severity of individual symptoms and the evaluation of overall diagnosis of dissociative disorder. Preliminary findings from a study of 48 subjects with and without psychiatric diagnoses indicate good to excellent reliability and discriminant validity for the SCID-D as a diagnostic instrument for the five dissociative disorders and as a tool for the evaluation of dissociative symptoms encountered within nondissociative syndromes.

Enhancing the hospital treatment of dissociative disorder patients by developing nursing expertise in the application of hypnotic techniques without formal trance induction.

Many symptoms suffered by dissociative disorder patients are unresponsive or incompletely responsive to medications. This poses a unique challenge to the staff of specialized dissociative disorder units, in which many such patients who require hospital care suffer serious distress that may not respond predictably to the pharmacological interventions that are available. However, the majority of their symptoms are dissociative in nature, and dissociative disorder patients generally are quite hypnotizable. Anticipating the need for nonpsychopharmacological interventions that we could use in the absence of the treating psychiatrist, we taught the unit's nursing and social work staff to rely on the inherent trance-proneness of these patients to utilize hypnotic techniques without the formal induction of hypnosis. Their implementation facilitated crisis resolution, led to a greater sense of safety on the part of the patients, enhanced the staff's sense of mastery, and minimized the need for emergency sedation and restraints.

Characteristics of patients with multiple personality and dissociative disorders on psychological testing.

We describe a new psychological testing procedure used on a consecutive series of 14 patients with multiple personality and dissociative disorders who met DSM-III-R and research criteria for dissociative disorders. Once dissociative phenomena were accounted for in testing, most patients displayed response patterns markedly different from those of schizophrenic and borderline patients. Patients showed striking variability on cognitive and projective tests, often related to posttraumatic intrusions. Rorschach protocols showed unusual thinking accompanied by psychological complexity and highly developed self-observing capacity. In contrast to classical conceptualizations about these patients, most subjects had personality profiles that were intellectualized, obsessive, and introversive, not histrionic or labile.

Clinical phenomenology of child and adolescent dissociative disorders.

A comparison of two separately diagnosed samples of children and adolescents with dissociative disorders demonstrates good construct validity for these diagnoses in childhood. Descriptive analyses of the total sample reveal a clinical profile characterized by a plethora of affective, anxiety, conduct, posttraumatic, and dissociative symptoms. Children with multiple personality disorder (MPD) differ from those with dissociative disorder not otherwise specified (DDNOS) in having more amnesias, identity disturbances, and hallucinations. Adolescents were more symptomatic than children age 11 or younger and more likely to receive a diagnosis of multiple personality disorder.

Dissociative disorders in children and adolescents. A developmental perspective.

Childhood and adolescent dissociative disorders are being diagnosed increasingly by mental health professionals who work with traumatized children. The identification of these conditions is hampered by the high background level of normal dissociative behavior observed in children and adolescents. An awareness of the underlying developmental processes and issues can aid in the identification of pathologic dissociation.

Sex therapy with dissociative disorders: a protocol.

Female victims of childhood sexual abuse who develop dissociative disorders often suffer from sexual dysfunction but do not receive sex therapy as often as might be expected due to the problems created by dissociative defenses. A modification of standard sex therapy techniques is proposed as a step toward restoring sexual function to this population. Key elements of the protocol are Eriksonian utilization of dissociative defenses, reduced expectations, and careful preparation of the male partner.

Substance-induced dissociative disorders and psychiatric nosology.

Transient amnesias, fugues, twilight states, automatisms, depersonalization, and furors or explosive disorders can occur in association with, or be caused by, various medications or substance-induced organic brain states. Agents capable of precipitating dissociative-like states include alcohol, barbiturates and similarly acting hypnotics, benzodiazepines, scopolamine, clioquinol, beta-adrenergic blockers, marijuana and certain psychedelic drugs, general anesthetics, and others. The presentations of substance-induced dissociative states may resemble those of functional dissociative disorders, or organic and psychogenic dissociative factors may coexist and be intertwined or indistinguishable. Organic dissociative states are distinct from intoxication, amnestic disorder, frank delirium, or other organic mental disorders as specified in DSM-III and DSM-III-R, yet these diagnostic manuals have no inclusive category or coherent nosological approach to dissociative states not strictly psychogenic in etiology. Substance-induced and other organic dissociative disorders can have clinical, medicolegal, and neuropsychological significance. They provide a unique opportunity for the study of mind-brain relationships and should be included in psychiatric nosology.

Dissociative Disorders

A case of probable dissociative disorder.

The case of a patient with symptoms suggestive of a dissociative disorder is presented. The consultant reviews the diagnosis of multiple personality disorder (MPD) as defined in DSM-III-R and DSM-IV in relation to the patient's dissociative states, hallucinations, memory loss, and other symptoms. He then highlights the distinctions among MPD, schizophrenia, borderline personality disorder, major depression, and complex partial seizures. After presenting the conceptualization of MPD as a chronic posttraumatic stress disorder, he concludes with a review of treatment approaches that address the traumatic history and that involve hypnosis to gain access to and control dissociative states.
