ABSTRACT
OBJECTIVE: Few studies have identified validity tests that are appropriate for use in individuals with dissociative identity disorder (DID). This study investigated whether the Morel Emotional Numbing Test (MENT) could distinguish between genuine and simulated DID. METHOD: Thirty-five participants with DID diagnosed via a semistructured interview were compared to 88 participants taking an abnormal psychology course who were instructed to simulate DID. Group comparison analyses were conducted to examine differences in the MENT errors. Univariate logistic regression and receiver operating characteristic curve analyses examined how well the MENT errors discriminated between groups and identified a cutoff optimizing sensitivity while maintaining high specificity. RESULTS: Simulators had significantly more errors across all three MENT sets compared to genuine DID participants. The total number of MENT errors across sets most strongly and significantly predicted genuine versus simulated DID groups. Receiver operating characteristic curve analyses indicated that the MENT could discriminate between genuine and simulated DID with outstanding classification accuracy (area under the curve = .95). A cutoff of ≥ 10 total errors on the MENT yielded an optimal balance of sensitivity (.86) and specificity (.94). However, the previously defined cutoff of ≥ 8 total errors also demonstrated high sensitivity (.87) and specificity (.89). CONCLUSIONS: Findings provide preliminary evidence for the MENT as a validity test for DID populations. Although the commonly used cutoff of ≥ 8 errors on the MENT demonstrated excellent psychometric properties, we recommend using a cutoff of ≥ 10 errors for individuals with DID to minimize the risk of false positives while maintaining strong sensitivity.

ABSTRACT
OBJECTIVE: Individuals with histories of complex psychological trauma, such as those with dissociative disorders, are often high utilizers of inpatient services and thus warrant further research attention. The present study sought to examine whether treatment on a specialized inpatient trauma unit was associated with improvements in adaptive functioning, emotion regulation, and dissociation among patients experiencing complex posttraumatic and dissociative symptoms. METHOD: This study used archival data collected as part of treatment provided to inpatients (N = 54), the majority of whom had a dissociative disorder, at a specialized trauma disorders unit to analyze differences in scores between intake and discharge on measures of adaptive functioning, emotion regulation, and dissociation. RESULTS: Adaptive functioning and emotion regulation were significantly improved at discharge compared to intake, t(299) = -11.28, p < .001; t(305) = 8.54, p < .001, respectively, with very large effect sizes (d = 1.60; d = 1.20), and there was a significant decrease, t(311) = 2.15, p = .032, d = .30, in dissociative absorption. CONCLUSIONS: Our findings suggest that inpatient treatment modeled after expert consensus treatment guidelines is associated with significant improvements in adaptive functioning and emotion regulation and reduced dissociative absorption in individuals experiencing severe and acute complex posttraumatic and dissociative symptoms. Appropriate screening and symptom-specific treatment of complex posttraumatic and dissociative symptoms are recommended to improve outcomes for this population during inpatient hospital admission.

ABSTRACT
Purpose: Complex dissociative disorders (CDDs) are prevalent among psychotherapy clients, and research suggests carefully paced treatment for CDDs is helpful. The purpose of the present study is to qualitatively explore helpful and meaningful aspects of the TOP DD Network programme, a web-based adjunctive psychoeducational programme for the psychotherapeutic treatment of clients with CDDs.Methods: TOP DD Network programme participants (88 clients and 113 therapists) identified helpful and meaningful aspects of their participation in response to two open textbox questions. Framework analysis was used to qualitatively analyze client and therapist responses.Findings: Participants found the TOP DD Network programme helpful and meaningful in nuanced ways. Three themes were created: (1) Components of the Programme (subthemes: content, structure), (2) Change-Facilitating Processes (subthemes: heightened human connection, receiving external empathy and compassion, contributing to something bigger, improved therapeutic work and relationship), and (3) Outcomes (subthemes: insight, increased hope, self-compassion, increased safety and functioning). The most emphasized theme was components of the programme, which captured its content and structure.Conclusion: Clients and therapists in the TOP DD Network programme described the programme's components and processes as helpfully facilitating positive outcomes in the treatment of CDDs. Therapists may consider integrating the components and processes in the programme into their practice with clients with CDDs.
The aim of the present study was to qualitatively explore significant aspects of the TOP DD Network programme through the experiences of complex dissociative disorder (CDD) clients and psychotherapists.Helpful and meaningful aspects of the programme included its components (i.e. content and structure), processes, and outcomes.This psychoeducational programme can be effective and result in improved therapeutic processes and outcomes for individuals with CDDs in psychotherapy.

OBJECTIVE: Past research found that undergraduate psychopathology textbooks present child maltreatment (CM) and its consequences inadequately or inaccurately. Given the prevalence and psychological impact of CM, it is essential that mental health professionals receive adequate training in CM, including trauma-related dissociation. Updated research is needed to determine whether current psychopathology textbooks adequately present information about CM and its consequences. METHOD: Ten undergraduate psychopathology textbooks were analyzed for the number of times CM was mentioned, number of Diagnostic and Statistical Manual of Mental Disorders (5th ed., Text Revision; DSM-5-TR) diagnostic categories CM was associated with, number of citations used to support claims about CM and related psychopathology, and coverage of trauma-related dissociation. RESULTS: Textbooks varied in their coverage of CM and dissociation. The average number of times CM-related keywords mentioned per book was 259.00 (SD = 110.42; range: 113-508). Childhood sexual abuse and sex trafficking received the most attention, followed by general references of child abuse or childhood trauma. The average number of citations provided with mentions of CM or related psychopathology for each textbook was 123.2 (SD = 77.44; range: 44-316). CM was stated to be associated with many DSM-5-TR diagnostic categories, including but not limited to trauma, dissociative, anxiety, mood, somatic, and personality disorders. The textbooks' coverage of dissociation was found to be largely inadequate, with most textbooks emphasizing popular media, the fantasy model of dissociation, and myths about dissociation. CONCLUSIONS: Undergraduate psychopathology textbooks need to improve their scholarly coverage of CM and its mental health consequences. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
ABSTRACT
INTRODUCTION: Dissociative identity disorder (DID) is a treatable mental health condition that is associated with a range of psychobiological manifestations. However, historical controversy, modern day misunderstanding, and lack of professional education have prevented accurate treatment information from reaching most clinicians and patients. These obstacles also have slowed empirical efforts to improve treatment outcomes for people with DID. Emerging neurobiological findings in DID provide essential information that can be used to improve treatment outcomes. AREAS COVERED: In this narrative review, the authors discuss symptom characteristics of DID, including dissociative self-states. Current treatment approaches are described, focusing on empirically supported psychotherapeutic interventions for DID and pharmacological agents targeting dissociative symptoms in other conditions. Neurobiological correlates of DID are reviewed, including recent research aimed at identifying a neural signature of DID. EXPERT OPINION: Now is the time to move beyond historical controversy and focus on improving DID treatment availability and efficacy. Neurobiological findings could optimize treatment by reducing shame, aiding assessment, providing novel interventional brain targets and guiding novel pharmacologic and psychotherapeutic interventions. The inclusion of those with lived experience in the design, planning and interpretation of research investigations is another powerful way to improve health outcomes for those with DID.

OBJECTIVE: This study sought to determine the utility of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in accurately distinguishing genuine dissociative identity disorder (DID) patients from coached and uncoached DID simulators. METHOD: DID patients (n = 34) who were diagnosed using the Structured Clinical Interview for DSM-IV-Dissociative Disorders were recruited from inpatient and outpatient settings. Coached (n = 25) and uncoached (n = 64) simulator groups were recruited from a Mid-Atlantic university. All participants completed the MMPI-2. RESULTS: MMPI-2 validity scales reliably distinguished simulators from DID patients with high sensitivity (0.95) and specificity (0.97). The scales showing greatest promise making the distinction were F minus K index, back infrequency scale, and superlative self-presentation. Simulators and genuine DID patients also differed in their pattern of symptoms. All results were calculated with White female DID patients and simulators only. CONCLUSIONS: Genuine DID patients can be differentiated from simulators. Simulators appear to overweight symptoms of paranoia and alienation relative to mood and somatic symptoms. Further research is needed to generalize these findings to male and non-White populations. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
ABSTRACT
Upto 86% of dissociative individuals engage in non-suicidal self-injury (NSSI). Research suggests that people who dissociate utilize NSSI to regulate posttraumatic and dissociative experiences, as well asrelated emotions. Despite high rates of NSSI, no quantitative study has examined the characteristics, methods, and functions of NSSIwithin a dissociative population. The present study examined thesedimensions of NSSI among dissociative individuals, as well aspotential predictors of intrapersonal functions of NSSI. The sample included 295 participants who indicated experiencing one or more dissociative symptoms and/or having been diagnosed with a trauma- or dissociation-related disorder. Participants were recruited through online trauma- and dissociation- related forums. Approximately 92% of participants endorsed a history of NSSI. The most common methods of NSSI were interfering with wound healing (67%), hitting oneself (66%), and cutting (63%). After controlling for age and gender, dissociation was uniquely associated with cutting, burning, carving, interfering with wound healing, rubbing skin against rough surfaces, swallowing dangerous substances, and other forms of NSSI. Dissociation was correlated with affect regulation, self-punishment,anti-dissociation, anti-suicide, and self-care functions of NSSI;however, after controlling for age, gender, depressive symptoms, emotion dysregulation, and PTSD symptoms, dissociation was no longer associated with any function of NSSI. Instead, only emotion dysregulation was associated with the self-punishment function ofNSSI and only PTSD symptoms were associated with the anti-dissociation function of NSSI. Understanding the unique properties of NSSI among dissociative individuals may improve the treatment of people who dissociate and engage in NSSI.

BACKGROUND: Individuals with dissociative identity disorder (DID) experience severe and broad-ranging symptoms which can be associated with elevations on measures designed to detect feigning and/or malingering. Research is needed to determine how to distinguish genuine DID from simulated DID on assessment measures and validity scales. OBJECTIVE: This study examined whether the Miller Forensic Assessment of Symptoms Test (M-FAST), a screening measure of malingering, could differentiate between individuals with DID and DID simulators. METHOD: Thirty-five individuals with clinical, validated DID were compared to 88 individuals attempting to simulate DID on the M-FAST. A MANCOVA compared the two groups on total M-FAST score and subscales. Univariate ANCOVA's examined differences between the groups. A series of logistic regressions were conducted to determine whether group status predicted the classification of malingering. Utility statistics evaluated how well the M-FAST discerned clinical and simulated DID. RESULTS: The M-FAST correctly classified 82.9% of individuals with DID as not malingering when using the suggested cut-off score of six. However, utilizing a cut-off score of seven correctly classified 93.6% of all participants and maintained adequate sensitivity (.96) but demonstrated increased specificity (.89). CONCLUSIONS: The M-FAST shows promise in distinguishing genuine DID when the cut-off score is increased to seven. This study adds to the growing body of literature identifying tests that can adequately distinguish clinical from simulated DID. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The 4-dimensional (4-D) model of trauma-related dissociation differentiates between dissociative experiences involving trauma-related altered states of consciousness and symptoms of distress that do not appear to involve alterations in normal waking consciousness across four phenomenological dimensions (i.e., our experience of time, thought, body, and emotions). The current study evaluated hypotheses associated with the 4-D model using analyses of variance and correlation analyses in individuals with a primary diagnosis of a trauma-related dissociative disorder who were participating in the TOP DD internet study involving a combination of in-person psychotherapy and an online psychoeducational program (n = 111). Intrusive memories of traumatic events were more frequently endorsed than flashbacks, but emotional numbing was more frequently endorsed than other forms of affect dysregulation. Negative thoughts and emotion dysregulation were more strongly intercorrelated than were voice hearing and emotional numbing. Distress symptoms were more strongly associated with PTSD symptoms and difficulties in emotion regulation, whereas experiences of depersonalization were more strongly associated with dissociative self-states. Greater reduction in distress symptoms was also seen in comparison with trauma-related altered states of consciousness over the course of the combined psychotherapy and internet-based psychoeducational intervention. Overall, results continue to suggest that measures of distress and dissociative experiences can be distinguished by measures of symptom frequency, co-occurrence, and convergence with other measures of distress vs. dissociation albeit that results varied across the four phenomenological dimensions that were surveyed.

Background: Dissociative disorders (DDs) are characterized by interruptions of identity, thought, memory, emotion, perception, and consciousness. Patients with DDs are at high risk for engaging in dangerous behaviours, such as self-harm and suicidal acts; yet, only between 28% and 48% of individuals with DDs receive mental health treatment. Patients that do pursue treatment are often misdiagnosed, repeatedly hospitalized, and experience disbelief from providers about their trauma history and dissociative symptoms. Lack of dissociation-specific treatment can result in poor quality of life, severe symptoms requiring utilization of hospitalization and intensive outpatient treatment, and high rates of disability. Objective: Given the extensive and debilitating symptoms experienced by individuals with DDs and the infrequent utilization of treatment, the current study explored barriers to accessing and continuing mental health treatment for individuals with dissociative symptoms and DDs. Method: A total of 276 participants with self-reported dissociative symptoms were recruited via online social media platforms. Participants completed a survey which featured 35 possible barriers to accessing treatment and 45 possible reasons for discontinuing treatment, along with open text boxes for adding barriers/reasons that were not listed. Results: Results showed 97% of participants experienced one or more barriers to accessing treatment (M = 9 barriers) and 92% stopped treatment with a provider due to at least one of the reasons captured in the survey (e.g. limited insurance coverage, poor therapeutic alliance, disbelief from providers, etc.; M = 7 barriers). Conclusions: The most frequently endorsed barriers were structural barriers, such as those related to finances, insurance, and lack of provider availability. It is imperative more service providers are trained to treat dissociation and that insurers and health care systems recognize the need for specialized, dissociation-focused treatment.
Antecedentes: Los trastornos disociativos (TD) se caracterizan por interrupciones en la identidad, pensamiento, memoria, emoción, percepción y conciencia. Los pacientes con TD tienen un alto riesgo de participar en conductas peligrosas, como autolesiones y actos suicidas; sin embargo, solo entre el 2848% de las personas con TD reciben tratamiento de salud mental. Los pacientes que buscan tratamiento a menudo son mal diagnosticados, hospitalizados repetidamente y experimentan incredulidad por parte de los proveedores sobre su historial de trauma y síntomas disociativos. La falta de un tratamiento específico para la disociación puede resultar en una mala calidad de vida, síntomas graves que requieren hospitalización y tratamiento ambulatorio intensivo y altas tasas de discapacidad.Objetivo: Dados los síntomas extensos y debilitantes que experimentan las personas con TD y la utilización poco frecuente del tratamiento, el presente estudio exploró las barreras para acceder y continuar el tratamiento de salud mental para las personas con síntomas disociativos y TD.Método: Un total de 276 participantes con síntomas disociativos auto-reportados fueron reclutados a través de plataformas de redes sociales en línea. Los participantes completaron una encuesta que presentaba 35 posibles barreras para acceder al tratamiento y 45 posibles razones para interrumpir el tratamiento, junto con cuadros de texto abiertos para agregar barreras/razones no incluidas en la lista.Resultados: Los resultados mostraron que el 97% de los participantes experimentó una o más barreras para acceder al tratamiento (M = 9 barreras) y el 92% interrumpió el tratamiento con un proveedor debido al menos a una de las razones capturadas en la encuesta (por ejemplo, cobertura de seguro médico limitada, pobre alianza terapéutica, incredulidad por parte de los proveedores, etc.; M = 7 barreras).Conclusiones: Las barreras confirmadas con mayor frecuencia fueron las barreras estructurales, como las relacionadas con las finanzas, los seguros médicos y la falta de disponibilidad de proveedores. Es imperativo que más proveedores de servicios estén capacitados para tratar la disociación y que las aseguradoras y los sistemas de atención médica reconozcan la necesidad de un tratamiento especializado centrado en la disociación.

Background: Dissociative disorder (DD) patients report high rates of self-injury. Previous studies have found dissociation and self-injury to be related to emotional distress. To the best of our knowledge, however, the link between emotion dysregulation and self-injury has not yet been examined within a DD population. Objective: The present study investigated relations between emotion dysregulation, dissociation, and self-injury in DD patients, and explored patterns of emotion dysregulation difficulties among DD patients with and without recent histories of self-injury. Method: We utilized linear and logistic regressions and t-test statistical methods to examine data from 235 patient-clinician dyads enrolled in the TOP DD Network Study. Results: Analyses revealed emotion dysregulation was associated with heightened dissociative symptoms and greater endorsement of self-injury in the past six months. Further, patients with a history of self-injury in the past six months reported more severe emotion dysregulation and dissociation than those without recent self-injury. As a group, DD patients reported the greatest difficulty engaging in goal-directed activities when distressed, followed by lack of emotional awareness and nonacceptance of emotional experiences. DD patients demonstrated similar patterns of emotion dysregulation difficulties irrespective of recent self-injury status. Conclusions: Results support recommendations to strengthen emotion regulation skills as a means to decrease symptoms of dissociation and self-injury in DD patients.
Antecedentes: Los pacientes con trastorno disociativo (DD en sus siglas en inglés) reportan altas tasas de autolesiones. Estudios anteriores han encontrado que la disociación y las autolesiones están relacionadas con el sufrimiento emocional. Sin embargo, hasta donde sabemos, la relación entre la desregulación emocional y las autolesiones aún no se ha examinado en una población con DD.Objetivo: El presente estudio investigó las relaciones entre la desregulación emocional, la disociación y la autolesión en pacientes con DD, y exploró los patrones de las dificultades de desregulación emocional entre los pacientes con DD con y sin historias recientes de autolesión.Método: Se utilizaron regresiones lineales y logísticas y métodos estadísticos de prueba t para examinar los datos de 235 díadas paciente-médico inscritas en el Estudio TOP DD Network.Resultados: Los análisis revelaron que la desregulación emocional se asoció con un aumento de los síntomas disociativos y una mayor tendencia a la autolesión en los últimos seis meses. Además, los pacientes con un historial de autolesiones en los últimos seis meses informaron de una desregulación emocional y una disociación más graves que los que no se habían autolesionado recientemente. Como grupo, los pacientes con DD informaron de la mayor dificultad para participar en actividades dirigidas a objetivos cuando estaban angustiados, seguidos por la falta de conciencia emocional y la no aceptación de las experiencias emocionales. Los pacientes con DD demostraron patrones similares de dificultades de desregulación emocional, independientemente del estado de autolesión reciente.Conclusiones: Los resultados apoyan las recomendaciones de fortalecer las habilidades de regulación de las emociones como medio para disminuir los síntomas de disociación y autolesión en pacientes con DD.

Background: Most individuals with dissociative disorders (DDs) report engaging in self-injury. Objective: The present study aimed to understand the reasons for self-injury among a clinical sample of 156 DD patients enrolled in the TOP DD Network study. Method: Participants answered questions about self-injury, including a prompt asking how often they are aware of the reasons they have urges to self-injure, as well as a prompt asking them to list three reasons they self-injure. Results: Six themes of reasons for self-injury, each with subthemes, were identified in the qualitative data: (1) Trauma-related Cues, (2) Emotion Dysregulation, (3) Stressors, (4) Psychiatric and Physical Health Symptoms, (5) Dissociative Experiences, and (6) Ineffective Coping Attempts. Participants reported that they were able to identify their reasons for self-injuring sometimes (60.26%) or almost always (28.85%), with only 3.20% unable to identify any reasons for their self-injury. Conclusion: Results suggest that the vast majority of DD patients (92.31%) reported being at least partially unaware of what leads them to have self-injury urges, and many individuals with DDs experience some reasons for self-injury that are different from those with other disorders. The treatment implications of these findings are discussed.
Antecedentes:La mayoría de los individuos con trastornos disociativos (DDs por sus siglas en inglés) informan realizarse autolesiones. Objetivo: El presente estudio tuvo como objetivo el comprender las razones de las autolesiones en una muestra clínica de 156 pacientes con DD enroladas en el estudio TOP DD Network.Método:Los participantes respondieron a preguntas sobre las autolesiones, incluyendo una pregunta sobre la frecuencia con la que son conscientes de las razones por las que se autolesionan, así como una pregunta que les pedía que enumeraran tres razones por las que se autolesionan.Resultados:En los datos cualitativos se identificaron seis temas de motivos de autolesión, cada uno con subtemas: (1) Claves relacionadas con el trauma, (2) Desregulación emocional, (3) Estresores, (4) Síntomas psiquiátricos y de salud física, (5) Experiencias disociativas y (6) Intentos de afrontamiento ineficaces. Los participantes informaron que pudieron identificar sus razones para autolesionarse a veces (60,26%) o casi siempre (28,85%), y solo el 3,20% no pudo identificar las razones de sus autolesiones.Conclusiones:Los resultados sugieren que la gran mayoría de los pacientes con DD (92.31%) informaron no ser, al menos parcialmente, conscientes de lo que los lleva a tener deseos de autolesionarse y muchos individuos con DDs experimentan algunas razones de autolesión que son distintas de las que padecen otros trastornos. Se discuten las implicaciones de estos hallazgos en el tratamiento.

OBJECTIVE: Academic training programs for mental health professionals rarely include comprehensive instruction on trauma, consequently leaving clinicians inadequately prepared to provide trauma treatment. The present study sought to: (a) ascertain what percentage of participants had received training in complex trauma and dissociation; (b) examine pre- and posttraining differences in knowledge related to complex trauma populations; and (c) investigate changes in participants' competence and empathy in working with survivors. METHOD: We examined self-reported changes in knowledge, competence, and empathy regarding individuals with complex trauma among mental health professionals who attended a complex trauma training workshop. Participants provided feedback about previous trauma training experience and areas of additional trauma training that they perceived would be beneficial. RESULTS: Prior to completing the program, 68% of participants reported feeling inadequately trained to assess trauma and 75% felt inadequately trained to treat trauma. Ten percent had not received training in complex trauma and 30% had not received training in treating patients with dissociative symptoms. Participants showed significant increases in knowledge and self-reported competence following the training. They suggested that learning about dissociation and dissociative disorders was the most helpful information gained and that learning more techniques and skills for complex trauma populations would improve their ability to treat this group. CONCLUSIONS: The majority of participants felt inadequately trained to treat clients who have experienced complex trauma and experienced dissociation. They reported the trauma training as beneficial in that it increased their sense of knowledge and competence about treating trauma-exposed individuals.

Background: Individuals with dissociative identity disorder (DID) have complex symptoms consistent with severe traumatic reactions. Clinicians and forensic assessors are challenged by distinguishing symptom exaggeration and feigning from genuine symptoms among these individuals. This task may be aided by administering validity measures. Objective: This study aimed to document how individuals with DID score on the Structured Inventory of Malingered Symptomatology (SIMS). The second objective was to compare coached DID simulators and healthy controls to DID patients on the SIMS's total score and subscales. The third objective was to examine the utility rates of the SIMS in distinguishing simulated DID from clinically diagnosed DID. Method: We compared SIMS data gathered from participants from two Dutch sites, one Swiss site and one U.S. site. Sixty-three DID patients were compared to 77 coached DID simulators and 64 healthy controls on the SIMS. A multivariate analysis compared the groups on the SIMS total scores and subscales, and post-hoc Games Howell tests and univariate ANOVAs examined differences between the groups. Utility statistics assessed the accuracy of the SIMS in distinguishing clinical from simulated DID. Results: DID simulators scored significantly higher than DID individuals and healthy controls on every SIMS subscale as well as the total score. The majority (85.7%) of the individuals with DID scored above the cut-off, which is typically interpreted as indicative of possible symptom exaggeration. DID individuals scored higher than the healthy controls on every subscale except Low Intelligence, even after controlling for dissociation. The subscales and items most frequently endorsed by the DID group are consistent with symptoms associated with complex trauma exposure and dissociative reactions. The SIMS total score had a sensitivity of 96% but an unacceptably low specificity of 14%. Conclusions: The findings indicate that the instrument is not accurate in assessing potential symptom exaggeration or feigning in DID.

Los clínicos y evaluadores forenses se enfrentan al reto de distinguir la exageración de los síntomas y la simulación de los síntomas genuinos entre estos individuos. Esta tarea puede verse facilitada por la administración de medidas de validez.Objetivo: Este estudio tuvo como objetivo documentar la puntuación de los individuos con TID en el Inventario Estructurado de Sintomatología Simulada (SIMS). El segundo objetivo era comparar los simuladores de TID entrenados y los controles sanos con los pacientes de TID en la puntuación total y las subescalas del SIMS. El tercer objetivo fue examinar los índices de utilidad del SIMS para distinguir el TID simulado del TID diagnosticado clínicamente.Método: Se compararon los datos de la SIMS obtenidos de participantes de dos centros holandeses, un centro suizo y un centro estadounidense. Se compararon 63 pacientes de TID con 77 simuladores de TID entrenados y 64 controles sanos en el SIMS. Un análisis multivariante comparó los grupos en las puntuaciones totales y subescalas de la SIMS, y las pruebas post-hoc de Games Howell y los ANOVAs univariantes examinaron las diferencias entre los grupos. Las estadísticas de utilidad evaluaron la precisión de la SIMS para distinguir el TID clínico del simulado.Resultados: Los simuladores de TID obtuvieron puntuaciones significativamente más altas que los individuos con TID y los controles sanos en cada subescala del SIMS, así como en la puntuación total. La mayoría (85,7%) de los individuos con TID puntuaron por encima del punto de corte, que suele interpretarse como indicativo de una posible exageración de los síntomas. Los individuos con TID puntuaron más alto que los controles sanos en todas las subescalas excepto en Inteligencia baja, incluso después de controlar la disociación. Las subescalas y los ítems más frecuentemente respaldados por el grupo de TID son consistentes con los síntomas asociados con la exposición al trauma complejo y las reacciones disociativas. La puntuación total del SIMS tuvo una sensibilidad del 96% pero una especificidad inaceptablemente baja del 14%.Conclusiones: Los resultados indican que el instrumento no es preciso para evaluar la potencial exageración o simulación de los síntomas en el TID.

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) revised the diagnostic criteria for dissociative identity disorder (DID) to more accurately reflect the symptom profile of DID patients. No study has examined how this change affects clinical diagnosis of DID. The present study examined clinician reports of patient symptoms in relation to DSM-IV-TR and DSM-5 DID diagnostic criteria. Data were analyzed from 169 clinicians who participated in the Treatment of Patients with Dissociative Disorders Network Study with a patient they assigned a DID diagnosis. Clinicians evaluated their patients with respect to DSM-IV-TR and DSM-5 DID diagnostic criteria. Researchers determined a clinician-assigned DID diagnosis as "accurate" when the patient's reported dissociative symptoms matched DSM-IV-TR and/or DSM-5 criteria for DID. Most of the clinicians (95.27%) accurately diagnosed DID. Of those accurately diagnosed, 83.85% of patients met DSM-IV-TR and DSM-5 DID criteria, 9.94% only met DSM-IV-TR DID criteria, and 6.21% only met DSM-5 DID criteria. Further examination of responses suggested that possible idiomatic responses to the negative wording of the DSM-5 exclusionary criteria might have accounted for the DSM-IV-TR appearing to fit for a greater number of cases in this study. Changes in the DSM criteria for DID did not substantially change the frequency or accuracy of assigned DID diagnoses, but the removal of the requirement in DSM-5 that self-states regularly take control of an individual's behavior slightly increased the number of individuals meeting criteria for DID.
ABSTRACT
Inaccurate diagnosis of dissociative disorders (DDs) remains a frequent problem. Misdiagnoses may lead to delayed or ineffective treatment, and subsequently poorer quality of life for those struggling with DDs, who frequently utilize mental health treatment and evidence high rates of self-harm and suicidality. This study's objective was to examine the magnitude of the effects with which the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D) and revised version (SCID-D-R) - henceforth referred to as the "SCID-D interviews" - provide diagnoses of DDs and differentiate them from nondissociative disorders as well as factitious and simulated dissociative presentations. For inclusion, studies had to be empirical investigations comparing SCID-D data of DD populations with other populations. Using combined methods of searching for "SCID-D" in electronic indexing databases, seeking recommendations from experts, and reviewing reference sections of identified studies, 15 studies were identified and subjected to meta-analytic review. Analyses showed that the overall SCID-D interview score (effect size 3.12) as well as each of the five subscales - particularly amnesia and identity alteration (effect sizes 2.16 and 2.87, respectively) - significantly differentiated DD from non-DD. Findings suggest that the SCID-D interviews show good validity identifying and differentiating those with DDs as compared to those without DDs. The SCID-D interviews are valid instruments for diagnosing and differentiating DD from other psychiatric disorders and feigned presentations of DD. Clinicians, researchers, and forensic experts can use the SCID-D interviews with confidence to make differential diagnoses of DDs. Future research using the SCID-D interviews is discussed.

Childhood trauma is common among survivors and perpetrators of intimate partner violence (IPV). Although symptoms of posttraumatic stress disorder (PTSD) and dissociative disorders (DDs) are predictors of IPV victimization and perpetration, few studies explore IPV among those with DDs. The present study examined IPV and symptoms as predictors among participants in the Treatment of Patients With Dissociative Disorders (TOP DD) Network study, an educational intervention for individuals with DDs and their clinicians. Both clinicians and patients reported on patients' history of physical, emotional, and sexual IPV as both victims and perpetrators. Patients self-reported dissociative, posttraumatic (PTSD), and emotion dysregulation symptoms, as well as IPV-specific dissociative symptoms. According to patients and clinicians, patients were frequently victims of IPV, most commonly emotional IPV. Dissociative symptoms predicted IPV exposure, whereas dissociative and emotion dysregulation symptoms predicted IPV-specific dissociative symptoms.

OBJECTIVE: Dissociative disorders (DDs) are associated with intensive, long-term treatment, suicidality, recurrent hospitalizations, and high rates of disability. However, little is known about the specifics of the economic burden associated with DDs. This worldwide, systematic review examines the results of studies in adults on direct and indirect costs associated with DDs. METHOD: We searched 6 databases and the reference lists of articles. We also approached researchers to identify unpublished studies. No language restrictions were imposed. RESULTS: A total of 1,002 records met the search criteria, of which 29 papers were selected for full-text inspection. Ultimately, of these, we reviewed four empirical studies. We provide a narrative discussion of study findings. Our findings suggest that DDs are costly to society, and that there is a reduction in service utilization and associated costs over time with diagnosing of and specialized treatment for DDs. However, the overall quality of the economic evaluations was low; several types of DDs, comorbid conditions, and costs were not included; and men were underrepresented. Due to the heterogeneity among studies, we could not perform a meta-analysis. CONCLUSIONS: Due to the heterogeneity and low quality of the identified economic evaluations, no firm conclusions about the economic burden of DDs alone can be drawn. Higher quality research, including a detailed description of the study design, population, and primary outcome measures used, utilizing appropriate clinical alternatives and including major comorbidities, is urgently needed to more rigorously assess the economic impact of DDs.

There is a shortage of clinicians who have been trained in treating traumatized clients, despite the high prevalence of trauma exposure and its frequent link with psychopathology. To address this need, professional guidelines and resources have been developed, including a core set of trauma competencies that professionals must develop to provide trauma-informed services to clients and several treatment guidelines. We discuss The New Haven Competencies for Trauma Training and Practice, then review recently developed clinical and professional practice guidelines, with an emphasis on the American Psychological Association (APA)'s Clinical Practice Guideline for the Treatment of Posttraumatic Stress Disorder (PTSD; "APA PTSD Guideline"). The APA PTSD Guideline was developed to guide clinicians in treatment planning for traumatized clients. However, numerous concerns about the Guideline and its limitations have been raised, and we present those that are relevant to training students and professionals about treating traumatized clients. We consider whether the APA Guideline is consistent with current trauma training needs, models, initiatives, and resources. We conclude that students and professionals who apply the treatments identified by the APA PTSD Guideline as "strongly supported" by empirical evidence may inadvertently overwhelm some clients with complex trauma presentations, which could result in poor outcomes or even harm. Furthermore, the Guideline does not adequately address aspects of treatment that are crucial to training about trauma, such as considering the client's cultural and individual needs and clinician self-care. We suggest training methods that take into consideration the limitations of the APA PTSD Guideline. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
