Somatoform and psychoform dissociation among women with orgasmic and sexual pain disorders

Since the 20th century, psychogenic female sexual dysfunctions (FSD), like some somatoform and conversion disorders, have been considered an expression of somatoform dissociation. Several studies have reported dissociative symptoms in different somatoform and conversion disorders, but limited data are available on dissociation among patients with FSD. The aim of this study was to assess somatoform and psychoform dissociation among patients with women's orgasmic disorder, dyspareunia, and vaginismus. A battery of self-administered questionnaires (Somatoform Dissociation Questionnaire, Dissociative Experiences Scale, Hospital Anxiety and Depression Scale, Impact of Event Scale-Revised) was given to 200 gynecological outpatients to assess psychoform and somatoform dissociation and their association with FSD. A strong association between somatoform dissociation and FSD was observed (adjusted odds ratio [OR] = 5.39, 95% confidence interval [CI] = 1.15-25.32), the association between somatoform and psychoform dissociation being estimated by an adjusted OR of 4.83 (95% CI = 1.17-19.91). Our results are compatible with the idea that some forms of FSD could be regarded as somatoform dissociative disorders.     

Early Traumatized Inpatients High in Psychoform and Somatoform Dissociation: Characteristics and Treatment Response

This study examined the clinical relevance of differences in psychoform and somatoform dissociative symptoms in 55 early traumatized inpatients. The high psychoform and somatoform dissociative group (n = 18), somatoform dissociative group (n = 22), and nondissociative group (n = 15) did not differ on abuse severity, depressive symptoms, interpersonal problems, Axis I or II comorbidity, or deterioration rates. Compared to the other 2 groups, the highly dissociative group was characterized by younger age, living alone, higher levels of posttraumatic and general distress, more frequent reports of suicidality, self-mutilation, eating problems, and less favorable treatment response. The results highlight the clinical relevance of using dissociation measures for identifying subgroups of patients with severe psychopathology who may be more treatment resistant.     

Differentiating Dissociative Disorders from Other Diagnostic Groups Through Somatoform Dissociation in Turkey

Abstract

This study aimed to assess the reliability, validity, and psychometric characteristics of the Turkish version of the Somatoform Dissociation Questionnaire (SDQ-20). In this context, it investigated whether somatoform dissociation differentiates dissociative disorders from other diagnostic groups and non-clinical individuals. The Turkish Version of the SDQ-20 was administered to 50 patients with a dissociative disorder, 94 patients with psychiatric disorders other than dissociative disorder, and 175 non-clinical participants. To confirm the clinical diagnosis, all patients in the dissociative disorder group had been evaluated using the Structured Clinical Interview for DSM-IV Dissociative Disorders. The internal consistency and the test-retest correlation of the SDQ-20 were excellent. The scale had strong correlations with the DES and the DIS-Q. There was a statistically significant difference between dissociative patients and other diagnostic groups on the SDQ-20 total score. The discriminative power of the SDQ-20 was as robust as that of the DES. There was no significant difference between the mean SDQ-20 total scores of Turkish and Dutch patients, but Turkish dissociative patients reported pseudoseizures more frequently than Dutch patients. The specificity of the short version of the scale (SDQ-5) was weak among Turkish patients. Dissociative disorders can be differentiated from other diagnostic groups through somatoform dissociation. The good psychometric characteristics of the SDQ-20 among Turkish participants support its cross-cultural validity.     

Somatoform Dissociation,Psychological Dissociation,and Specific Forms of Trauma

Abstract

Background: Childhood trauma is clearly associated with psychological dissociation a failure to integrate cognitive, behavioural and emotional aspects of experience. However, there is also evidence that trauma results in somatoform dissociation, where the individual fails to process somatic experiences adequately. Somatoform dissociation is linked to a number of psychiatric disorders that are relatively resistant to treatment. The present study addresses the hypothesis that somatoform dissociation will be associated specifically with childhood trauma that involves physical contact, rather than with non-contact forms of trauma.

Methods: An unselected clinical group of 72 psychiatric patients completed standardized measures of childhood trauma, psychological dissociation, and somatoform dissociation.

Results: The findings supported the hypothesis, with a specific link between somatoform dissociation and the severity of reported childhood trauma involving physical contact or injury. In contrast, psychological dissociation was associated with a wider range of non-contact trauma.

Conclusions: Somatoform dissociation can be understood as a set of adaptive psychophysiologic responses to trauma where there is a threat of inescapable physical injury. Those responses are related to a range of psychiatric disorders, and are likely to interfere with treatment of those disorders. Clinicians may need to assess the nature and severity of childhood trauma and somatoform dissociation when there are high levels of somatic symptoms within psychiatric disorders that cannot be explained medically. Further research is needed to determine methods of treating somatoform dissociation, especially in the context of a history of trauma involving physical contact or injury.     

Somatoform Dissociation in Traumatized World War I Combat Soldiers

Abstract

The massive traumatization of World War I combat soldiers led to an unprecedented incidence of somatoform dissociative disorders and symptoms, usually diagnosed as hysterical disorders during the war years. Following a brief overview of the scope of the suffering during this Great War, attention is given to British army psychiatrist Charles S. Myers' (1940) observations of the alternation between a so-called “emotional” personality and an “apparently normal” personality in traumatized combat soldiers. Somatoform dissociation, further categorized into positive and negative symptoms, is related to this structural dissociation, and to fixation in the trauma and avoidance of the trauma, and may be part of a more encompassing symptomatology. Next, a short overview of diagnostic issues is given. We argue that the DSM-IV category of “conversion disorder” is incorrect. Rather, the findings revealed here support Janet's classic and Nijenhuis' more recent views on somatoform dissociation. Finally, treatment issues are briefly presented.     

The Interrelatedness of Disconnection: The Relationship Between Dissociative Tendencies and Alexithymia

ABSTRACT

This study explored the extent to which alexithymia can be seen as a dissociative phenomenon, examining three facets of dissociation in relationship to the five dimensions of alexithymia. The dissociative facets were: pathological psychoform dissociation (amnesia and derealization/depersonalization), non-pathological psychoform dissociation (absorption) and somatoform dissociation. The alexithymia facets were: difficulties emotionalizing, fantasizing, identifying, verbalizing and analyzing emotions. Various self-report measures were used including the latest developed measure of alexithymia, the Bermond Vorst Alexithymia Questionnaire (BVAQ). Canonical correlation results indicated that somatoform dissociation was the strongest predictor of alexithymia. For younger males, somatoform dissociation was directly related to all facets of alexithymia except for fantasizing. Males with somatoform dissociation, irrespective of age, appeared to have the highest difficulties emotionalizing and identifying emotions. Whilst somatoform and pathological psychoform dissociation were related to difficulties identifying emotions for younger females, no type of dissociation directly influenced the development of any alexithymia dimension for women.     

Emotion Regulation Processes and Psychoform and Somatoform Dissociation in Adolescents and Young Adults with Cumulative Maltreatment

The relationship between childhood trauma and dissociative experiences is widely acknowledged. However, the association between emotion regulation difficulties (ERD), anxiety/depression and dissociation in adolescents and young adults with cumulative maltreatment (CM) remains unclear. The present study examined the role of ERD at both intrapersonal and interpersonal levels and anxiety/depression symptoms in the development of psychoform or somatoform dissociation in adolescents and young adults with CM. We assessed 58 participants with CM and 55 participants without childhood trauma history between the age of 12 and 22 years old. Participants completed self-reports of ERD, anxiety/depression, psychoform dissociation and somatoform dissociation. The results revealed that adolescents and young adults exposed to CM displayed high levels of psychoform and somatoform dissociation, ERD and anxiety/depression symptoms. It was also found that intrapersonal and interpersonal ERD predicted psychoform dissociation, whereas anxiety/depression predicted somatoform dissociation in adolescents and young adults with CM. Intrapersonal and interpersonal ERD and anxiety/depression are therapy targets for clinical interventions in adolescents and young adults with CM and dissociative symptoms.     

Eye movement desensitization and reprocessing in the psychological treatment of trauma‐based psychogenic non‐epileptic seizures

Little is known about the types of mental health treatment that are most effective for psychogenic non‐epileptic seizure (PNES) patients who have high rates of comorbid post‐traumatic stress disorder (PTSD) and dissociation. Eye movement desensitization and reprocessing (EMDR) has proved to be effective in the treatment of PTSD, anxiety states, dissociative symptoms and somatoform disorders. This study, which utilized a non‐controlled qualitative multiple revelatory case design, integrates EMDR into the psychological treatment of PNES patients with confirmed trauma experiences. With EMDR targeting trauma and dissociative symptoms in three patients, PNES were extinguished in two. Those patients have remained seizure‐free for 12–18 months.

Peritraumatic Somatoform and Psychological Dissociation in Relation to Recall of Childhood Sexual Abuse

Abstract

Objective: Overwhelming experience can evoke psychological dissociation during or immediately after the event, including dissociative amnesia. Whereas some data suggest that such peritraumatic dissociation can also find expression in somatoform symptoms, only a limited range of such symptoms has been systematically studied. The present study hypothesized that peritraumatic psychological and somatoform dissociation are associated with each other, with delayed recall of childhood sexual abuse (CSA), and with CSA severity. Because current somatoform dissociation is most strongly associated with recalled childhood physical abuse (CPA), we also hypothesized that peritraumatic somatoform dissociation is associated with reported CPA over and above CSA.

Method: Thirty-four Dutch women who reported CSA were interviewed using a modified version of the Traumatic Memory Inventory (TMI) which assesses the characteristics of traumatic memories. The participants also completed the Traumatic Experiences Checklist, the Peritraumatic Dissociation Experiences Questionnaire, and the Peritraumatic Somatoform Dissociation Questionnaire.

Results: Peritraumatic psychological and somatoform dissociation were associated with each other, with delayed recall of trauma, and with severity of reported CS A. Reported CPA predicted peritraumatic somatoform dissociation over and above the severity of CS A in terms of the acts involved. Approximately 44% of the women reported independent corroboration of the abuse. Similar proportions of delayed, partial, and continuous CSA memories were corroborated.

Conclusions: This retrospective study suggested that delayed recall of CSA is associated with peritraumatic dissociation and CSA severity. It also suggested that trauma-especially that which involves serious threat to the integrity of the body-may evoke somatoform dissociation. Based on patient report, delayed recall of some CSA memories was as accurate as continuous recall of CSA.     

Guidelines for Treating Dissociative Identity Disorder in Adults (2005)

ABSTRACT

A novel sociocognitive theory of dissociation and dissociative disorders is proposed. The model, which is both theoretical and clinical, is based on “functional dissociation of the self.” A new concept is introduced in this paper: the sociological self. While the sociological self may have cultural and societal dimensions, it is regarded here as a universal phenomenon rather than a culture-bound one; as an individual psychological instance rather than a sociological concept per se. It is proposed that the main sources of dissociation are trauma-related detachment of the sociological and psychological selves and the subsequent amplification of the sociological self. Thus, effective psychotherapy must curtail the enlargement of the sociological self and reactivate the psychological self. It is hoped that this conceptualization will contribute to efforts both toward understanding the everyday dissociation of the average contemporary individual and toward developing novel psychotherapeutic approaches which might shorten the length of treatment of dissociative disorders.     

Reconsidering the autohypnotic model of the dissociative disorders

The dissociative disorders field and the hypnosis field currently reject the autohypnotic model of the dissociative disorders, largely because many correlational studies have shown hypnotizability and dissociation to be minimally related (r = .12). Curiously, it is also widely accepted that dissociative patients are highly hypnotizable. If dissociative patients are highly hypnotizable because only highly hypnotizable individuals can develop a dissociative disorder – as the author proposes – then the methodology of correlational studies of hypnotizability and dissociation in random clinical and community samples would necessarily be constitutively unable to detect, and statistically unable to reflect, that fact. That is, the autohypnotic, dissociative distancing of that small subset of highly hypnotizable individuals who repeatedly encountered intolerable circumstances is statistically lost among the data of (1) the highly hypnotizable subjects who do not dissociate and (2) subjects (of all levels of hypnotizability) who manifest other kinds of dissociation. The author proposes that, when highly hypnotizable individuals repeatedly engage in autohypnotic distancing from intolerable circumstances, they develop an overlearned, highly-motivated, automatized pattern of dissociative self-protection (i.e., a dissociative disorder). The author urges that theorists of hypnosis and the dissociative disorders explicitly include in their theories (a) the trait of high hypnotizability, (b) the phenomena of autohypnosis, and (c) the manifestations of systematized, autohypnotic pathology. Said differently, the author is suggesting that autohypnosis and autohypnotic pathology are unacknowledged nodes in the nomothetic networks of both hypnosis and dissociation.     

The Multidimensional Inventory of Dissociation (MID): A Comprehensive Measure of Pathological Dissociation

ABSTRACT

This article describes the development and validation of the Multidimensional Inventory of Dissociation (MID). The MID is a 218-item, self-administered, multiscale instrument that comprehensively assesses the phenomenological domain of pathological dissociation and diagnoses the dissociative disorders. The MID measures 14 major facets of pathological dissociation; it has 23 dissociation diagnostic scales that simultaneously operationalize (1) the subjective/ phenomenological domain of pathological dissociation and (2) the hypothesized dissociative symptoms of dissociative identity disorder (Dell, 2001a). The MID was designed for clinical research and for diagnostic assessment of patients who present with a mixture of dissociative, posttraumatic, and borderline symptoms. The MID demonstrated internal reliability, temporal stability, convergent validity, discriminant validity, and construct validity. The MID also exhibited incremental validity over the Dissociative Experiences Scale (DES) by predicting an additional 18% of the variance in weighted abuse scores on the Traumatic Experiences Questionnaire (TEQ). Confirmatory factor analysis (CFA) did not support a one-factor model of the MID's clinical scales (i.e., the 14 facets and the 23 diagnostic symptoms). In contrast, however, CFA of the MID's factor scales (Dell & Lawson, 2005) has strongly supported a one-factor model. It was concluded that both the MID's 168 dissociation items and the construct of pathological dissociation have a second-order, unifactorial structure.     

Dissociation,Psychiatric Symptoms,and Personality Traits in a Non-Clinical Population

ABSTRACT

This study investigated the relationship between dissociation and psychiatric symptoms as well as between dissociation and personality traits in a student population using the Dissociative Experiences Scale (DES), the Brief Symptom Inventory (BSI), and the Eysenck Personality Questionnaire (EPQ). The results indicate a strong association between dissociation and psychiatric symptoms in general as well as an association between dissociation and neuroticism. Both associations are primarily mediated through more benign forms of dissociation. Additionally, phobic anxiety and paranoid ideation from the BSI were found to account for 52.5% of the variance in DES-scores. Two components of dissociation, psychological and somatoform, as well as the relevance of considering both cognitive and affective factors in the dissociative process are discussed.     

Narcissism,a Relational Aspect of Dissociation

ABSTRACT

Pathological narcissism is an inevitable result of trauma-generated dissociation. It is also a relational aspect of dissociation, for in dissociative psychopathology the mutuality of relationships, both interpersonal and intrapsychic, has collapsed in significant ways. Dissociation of both aggression and dependency characterizes the “closed system.” While an open system allows interaction with the outside and transformation of the individual through interactive interchange with another, a closed system precludes transformation and intersubjectivity. Grandiose, domineering self-states may be understood as procedural, somatoform, dyadic enactments. These working models of attachment are at the core of much of the narcissistic entitlement, grandiosity, domination, and self-sufficiency that are so often found in dissociative disorders and in narcissism. It is possible to have a real impact on the closed system of narcissistic psychopathology by providing a safe attachment within the therapeutic relationship, and empathizing with the expression of self-protective aggression while containing its destructiveness. As a safe attachment figure with expertise, the therapist has the opportunity to facilitate positive transformation.     

Dissociation and Schizophrenia

Abstract

Comorbidity of psychotic and dissociative disorders often is not reported. This 38 year-old female with a history of schizophrenic symptoms displayed evidence of dissociative identity disorder (DID) during admission to an inpatient psychiatric unit. The case illustrates how the presence of a dissociative disorder may influence the presentation of a co-morbid psychosis. The historical association and differential diagnosis between DID and schizophrenia is described. Implications of various treatment approaches for patients exhibiting dissociation in the context of psychosis are discussed.     

Discriminating Dissociative Identity Disorder from Schizophrenia and Feigned Dissociation on Psychological Tests and Structured Interview

ABSTRACT

Objective: The purpose of this study was to evaluate the relative efficacy of a number of psychological tests and interviews in discriminating dissociative identity disorder (DID) from feigned dissociation and schizophrenia.

Method: Three measures of dissociation (SCID-D, DES, SDQ-5) two personality measures (MMPI-2, Millon-III) and a brief measure of hypnotic susceptibility (Spiegel & Spiegel's Eye-Roll Sign) were assessed for their ability to differentiate these diagnostic groups.

Results: Results indicate that the SCID-D was clearly the most efficacious instrument in discriminating DID from schizophrenia and from feigned dissociation. The DES-Taxon and the SDQ-5 were adequate in screening pathological dissociation from schizophrenia but were less discriminative of feigned dissociation. The commonly used personality inventories were unable to detect feigned dissociation and the DID group tended to have higher elevations on scales measuring psychotic symptoms than did the schizophrenic group. The Eye-Roll Sign discriminated feigned dissociation from those with dissociative disorders.

Conclusions: Structured interviews such as the SCID-D, although resource consuming, are essential in comprehensive assessment of dissociative disorders. Comprehensive assessment of psychotic disorders should include some measure of dissociation.     

Obsessive Compulsive Spectrum Disorders in Individuals with Dissociative Disorders

Abstract

The spectrum of Obsessive Compulsive Disorders is briefly presented. The phenomenological and neurophysiological overlap of these conditions with dissociation is described. Three case reports are used to illustrate these overlaps. All three cases have histories of early childhood trauma, dissociative symptoms and features of Obsessive Compulsive Spectrum Disorders that have proven to be treatment resistant with previous cognitive/behavioural and pharmacological interventions. The three cases illustrate that, in at least some individuals with dissociative disorders, a psychodynamic understanding of their Obsessive Compulsive symptoms is an important part of their successful treatment.     

Peritraumatic Dissociation and Emotions as Predictors of PTSD Symptoms Following Childbirth

ABSTRACT

The current study investigated the contributive role of perinatal dissociative and perinatal emotional responses to the development of PTSD symptoms following childbirth. Method: Using a prospective, longitudinal design, 140 women were studied who were followed from the first week after delivery to three months postpartum. Results: Three women (2.1%) met criteria for PTSD and 21.4% reported a traumatic childbirth experience. Both perinatal negative emotional reactions and perinatal dissociative reactions were the predictors of PTSD symptoms at three months postpartum. The effect of perinatal dissociation, however, was partially mediated by perinatal emotional reactions. Conclusion: Posttraumatic stress disorder can be a consequence of the experience of childbirth. Women who reported high levels of negative emotions during and shortly after childbirth were more likely to develop PTSD symptoms than women who did not. Women who experienced an instrumental delivery and also reported higher levels of psychoform perinatal dissociation, were at higher risk than women who reported higher levels of perinatal dissociation during a spontaneous delivery. These findings add to the growing body of literature regarding traumatic childbirth and indicate that perinatal dissociative and emotional phenomena are associated with posttraumatic stress.     

The Language of Dissociation

ABSTRACT

Three case studies of inner-city elementary school children illustrate the connection between speech-language disorders and dissociative disorders in children who have known or suspected trauma histories. The role of speech language pathologists in identifying and responding to dissociative symptoms in children is explored. Lack of adequate training concerning the impact of trauma and scarce literature on the communication profiles of dissociative children contributes and greatly impacts the diagnosis, referral, and treatment of these children. The case studies demonstrate how unusual speech and language symptoms and awareness of dissociative features may aid in identifying trauma-related problems and instituting effective treatment. Grounding techniques and specific language interventions can assist children in acquiring the vocabulary needed for communicating both their daily experiences and traumatic histories. The nature of the relationship between dissociation and communication disorders is explored, and the importance of future research, interdisciplinary collaboration, and trauma training in the speech-language curriculum is emphasized.     

Should conversion disorder be reclassified as a dissociative disorder in DSM V?

Pseudoneurological symptoms (i.e., conversion disorder), historically subsumed within the "hysteria" concept alongside phenomena such as psychogenic amnesia and multiple personality disorder, have been classified as somatoform disorders since DSM-III. Since then, there have been repeated calls to reclassify conversion disorder with the dissociative disorders, as in ICD-10. The authors review issues such as the high correlations between pseudoneurological and dissociative symptoms, the high rates of trauma reported for both groups, and the position that these phenomena share underlying processes. Although reintegrating pseudoneurological symptoms with the dissociative disorders is not without complications, there is a strong case for such a reclassification.
