  • Spirituality and Ego strength in Dissociative Identity Disorder Joan Weathersbee Ellason, MS, LPC
    American journal of pastoral counseling, 2020
    Co-Authors: Colin A. Ross
    Abstract:

    The authors administered the Spiritual Orientation Inventory and the Ego Resiliency Scale to 23 subjects with Dissociative Identity Disorder and 23 comparison subjects scoring below 30 on the Dissociative Experiences Scale. All subjects in both groups reported childhood physical and/or sexual abuse, were in treatment at a psychiatric hospital or in private practices, and met criteria for major depressive episode. The Dissociative Identity Disorder subjects did not differ from the comparison subjects on ego resiliency and scored higher on the measure of spirituality.

  • When to Suspect and How to Diagnose Dissociative Identity Disorder
    Journal of Emdr Practice and Research, 2015
    Co-Authors: Colin A. Ross
    Abstract:

    Previously undiagnosed Dissociative Identity Disorder (DID) may be present in individuals being assessed for eye movement desensitization and reprocessing (EMDR). Previously undiagnosed DID was present in 3.9% of 1,529 general adult psychiatric inpatients in 10 studies conducted in 6 different countries. In this article, a case of likely DID that was missed in a published case report is presented, and guidelines for when to suspect and how to diagnose DID are provided. Such guidelines are missing from the training of many mental health professionals.

  • co occurrence of Dissociative Identity Disorder and borderline personality Disorder
    Journal of Trauma & Dissociation, 2014
    Co-Authors: Colin A. Ross, Lynn Ferrell, Elizabeth Schroeder
    Abstract:

    The literature indicates that, among individuals with borderline personality Disorder, pathological dissociation correlates with a wide range of impairments and difficulties in psychological function. It also predicts a poorer response to dialectical behavior therapy for borderline personality Disorder. We hypothesized that (a) Dissociative Identity Disorder commonly co-occurs with borderline personality Disorder and vice versa, and (b) individuals who meet criteria for both Disorders have more comorbidity and trauma than individuals who meet criteria for only 1 Disorder. We interviewed a sample of inpatients in a hospital trauma program using 3 measures of dissociation. The most symptomatic group was those participants who met criteria for both borderline personality Disorder and Dissociative Identity Disorder on the Dissociative Disorders Interview Schedule, followed by those who met criteria for Dissociative Identity Disorder only, then those with borderline personality Disorder only, and finally those...

  • symptom patterns in Dissociative Identity Disorder patients and the general population
    Journal of Trauma & Dissociation, 2010
    Co-Authors: Colin A. Ross, Laura Ness
    Abstract:

    The authors used the Dissociative Disorders Interview Schedule to compare structured interview symptom patterns in a general population sample (N= 502) and a sample of patients with clinical diagnoses of Dissociative Identity Disorder (N= 303). Based on the Trauma Model, the authors predicted that the patterns would be similar in the 2 samples and that symptom scores would be higher in participants reporting childhood sexual abuse in both samples. They predicted that symptom scores would be higher among women with Dissociative Identity Disorder reporting sexual abuse than among women in the general population reporting sexual abuse, with the clinical sample reporting more severe abuse. These predictions were supported by the data. The authors conclude that symptom patterns in Dissociative Identity Disorder are typical of the normal human response to severe, chronic childhood trauma and have ecological validity for the human race in general.

  • Errors of Logic and Scholarship Concerning Dissociative Identity Disorder
    Journal of Child Sexual Abuse, 2009
    Co-Authors: Colin A. Ross
    Abstract:

    The author reviewed a two-part critique of Dissociative Identity Disorder published in the Canadian Journal of Psychiatry. The two papers contain errors of logic and scholarship. Contrary to the conclusions in the critique, Dissociative Identity Disorder has established diagnostic reliability and concurrent validity, the trauma histories of affected individuals can be corroborated, and the existing prospective treatment outcome literature demonstrates improvement in individuals receiving psychotherapy for the Disorder. The available evidence supports the inclusion of Dissociative Identity Disorder in future editions of the Diagnostic and Statistical Manual of Mental Disorders.

  • frequency of Dissociative Identity Disorder in the general population in turkey
    Comprehensive Psychiatry, 1999
    Co-Authors: Gamze Akyuz, Orhan Doǧan, Ilhan L Yargic, Hamndi Tutkun
    Abstract:

    This study attempted to determine the prevalence of Dissociative Identity Disorder in the general population. The Dissociative Experiences Scale (DES) was administered to 994 subjects in 500 homes who constituted a representative sample of the population of Sivas City, Turkey. The mean DES score was 6.7 ± 6.1 (mean ± SD). Of the 62 respondents who scored above 17 on the DES, 32 (51.6%) could be contacted during the second phase of the study. They were matched for age and gender with a group of respondents who scored below 10 on the scale, and the Dissociative Disorders Interview Schedule (DDIS) was then administered to both groups. Seventeen subjects (1.7%) received a diagnosis of Dissociative Disorder according to the structured interview. In the third phase, eight of 17 subjects who had a Dissociative Disorder on the structured interview could be contacted for a clinical evaluation. They were matched with a nonDissociative control group and interviewed by a clinician blind to the structured interview diagnosis. Four of eight subjects were diagnosed clinically with Dissociative Identity Disorder, yielding a minimum prevalence of 0.4%. Dissociative Identity Disorder is not rare in the general population. Self-rating instruments and structured interviews can be used successfully for screening these cases. Our data, derived from a population with no public awareness about Dissociative Identity Disorder and no exposure to systematic psychotherapy, suggest that Dissociative Identity Disorder cannot be considered simply an iatrogenic artifact, a culture-bound syndrome, or a phenomenon induced by media influences.

  • comparison of Dissociative Identity Disorder with other diagnostic groups using a structured interview in turkey
    Comprehensive Psychiatry, 1998
    Co-Authors: Ilhan L Yargic, Hamndi Tutkun, Behiye Alyanak
    Abstract:

    Twenty patients with Dissociative Identity Disorder (DID), 20 with schizophrenic Disorder, 20 with panic Disorder, and 20 with complex partial epilepsy were evaluated with the Dissociative Disorders Interview Schedule (DDIS) and the Dissociative Experiences Scale (DES). Subjects with Dissociative Identity Disorder were more frequently diagnosed as having somatization Disorder, past or concurrent major depressive episode, borderline personality Disorder, depersonalization Disorder, and Dissociative amnesia than other groups. They reported Schneiderian symptoms and extrasensory perceptions more frequently. In their anamnesis suicide attempts, trance states, sleepwalking, and childhood traumas were more frequent than those in comparison groups. The secondary features of Dissociative Identity Disorder and the DES score differentiated these patients from comparison groups significantly. DID has a set of clinical features different from that of schizophrenic Disorder, panic Disorder and complex partial epilepsy. The differences are similar to those yielded previously in studies from North America.

  • structured interview data on 35 cases of Dissociative Identity Disorder in turkey
    American Journal of Psychiatry, 1996
    Co-Authors: L I Yargic, Hamndi Tutkun
    Abstract:

    OBJECTIVE: The aim of this study was to describe the clinical features of Dissociative Identity Disorder in a group of Turkish patients as assessed with a structured interview. METHOD: Thirty-five consecutive patients at the Dissociative Disorders program of a university psychiatric clinic who met the DSM-IV criteria for Dissociative Identity Disorder were included in this study. The subjects were assessed with the Turkish versions of the Dissociative Disorders Interview Schedule and the Dissociative Experiences Scale. A descriptive analysis of the clinical features was carried out. RESULTS: Most (88.6%) of the patients were women. The mean age of the group was 22.8 years. Childhood physical or sexual abuse was reported by 77.1% of the patients. The mean Dissociative Experiences Scale score was 49.1. The patients reported an average of 12.5 somatic symptoms, 6.2 Schneiderian symptoms, 10.0 secondary features of the Disorder, 3.8 borderline personality Disorder criteria, and 4.1 extrasensory experiences. CONCLUSIONS: Dissociative Identity Disorder has a stable, consistent set of features throughout North America, in the Netherlands, and in Turkey. Cross-cultural research using standardized assessment measures will be invaluable in further illumination of the validity of this widely neglected psychiatric category. Language: en

  • scl 90 r norms for Dissociative Identity Disorder
    Journal of Trauma & Dissociation, 2004
    Co-Authors: Joan W. Ellason, Colin A. Ross
    Abstract:

    Norms for Dissociative Identity Disorder (DID) have been provided for a variety of structured interviews, self-report measures and computer-scored instruments. The SCL-90-R is a widely used self-report measure of general psychopathology, but prior to this report norms for DID were not available. The authors provide scores on the SCL-90-R for 101 participants with DID at baseline, and for 36 of the participants on two-year follow-up.

  • two year follow up of inpatients with Dissociative Identity Disorder
    American Journal of Psychiatry, 1997
    Co-Authors: Joan W. Ellason, Colin A. Ross
    Abstract:

    Objective: A group of 135 inpatients with Dissociative Identity Disorder was followed for 2 years to monitor treatment outcome. Method: Fifty-four of the patients were located and reassessed after a 2-year period through the use of the same self-report measures and structured clinical interviews that had been initially administered. Results: The patients showed marked improvement on Schneiderian first-rank symptoms, mood and anxiety Disorders, Dissociative symptoms, and somatization, with a significant decrease in the number of psychiatric medications prescribed. Patients who were treated to integration were significantly more improved than those who had not yet reached integration. Conclusions: These findings, although preliminary, provide empirical validation of previous clinical impressions that patients with Dissociative Identity Disorder may respond well to treatment.

  • lifetime axis i and ii comorbidity and childhood trauma history in Dissociative Identity Disorder
    Psychiatry MMC, 1996
    Co-Authors: Joan W. Ellason, Colin A. Ross, Dayna L Fuchs
    Abstract:

    According to DSM-IV, Dissociative Identity Disorder is characterized by the existence within the person of two or more distinctly different identities or personality states that from time to time take executive control of the person's body and behavior, with accompanying amnesia (American Psychiatric Association, 1994). By retrospective patient report, Dissociative Identity Disorder usually occurs in conjunction with severe childhood trauma (Kluft 1985; Putnam et al. 1986; Ross 1989; Ross et al. 1989a, 1990a). The Disorder appears to be the most severe form of disturbance on the Dissociative Disorders continuum (Boon and Draijer 1993; Coons 1992; Ross 1985; Ross et al. 1992). There is evidence that Dissociative Identity Disorder may be more prevalent than once believed in the general population (Ross 1991) and among general adult psychiatric inpatients (Latz et al. 1995; Ross et al. 1991; Saxe et al. 1993).
