Presence of the dissociative subtype of PTSD does not moderate the outcome of intensive trauma-focused treatment for PTSD

Dissociative Subtype of Posttraumatic Stress Disorder and its Correlates Among Treatment-Seeking Refugees

The dissociative subtype of posttraumatic stress disorder (PTSD-DS) denotes a severe type of PTSD associated with complex trauma exposure and psychiatric comorbidity. Refugees may be at heightened risk of developing PTSD-DS, but research is lacking. This cross-sectional study aimed to examine PTSD-DS and its demographic, trauma-related, and clinical correlates among a convenience sample of refugee patients over 18 years old who were diagnosed with PTSD according to DSM-5. PTSD-DS (Clinician-Administered PTSD Scale for DSM-5), trauma exposure (Life Events Checklist for DSM-5) and general psychopathology (Brief Symptom Inventory) were assessed at intake. T-tests, chi-square tests, and logistical regression analysis were conducted. The final sample consisted of 552 participants (177 (32.1%) women; 375 (67.9%) men; average age 40.0 years (SD = 11.2)) who originated from 63 countries. Of those, 158 (28.6%) met criteria for PTSD-DS. Participants with PTSD-DS scored significantly higher on PTSD symptom severity (t(550)=-5.270, p < .001), number of traumatic event types (t(456)=-3.499, p < .001), and exposure to sexual assault (χ(1) = 6.471, p = .01) than those without PTSD-DS. The odds of having PTSD-DS increased by 14.1% with exposure to each additional traumatic event type (OR = 1.141, CI 0.033-1.260). In conclusion, around 29% of adult treatment-seeking refugees with PTSD met the criteria for PTSD-DS. Those exposed to multiple traumatic event types including sexual assault, regardless of sex, were especially at risk. Having PTSD-DS was associated with more severe PTSD. Prioritizing trauma-focused treatment for those with PTSD-DS is recommended.

Factors influencing quality of processing in EMDR therapy

This study presents a preliminary analysis of a new instrument oriented at the analysis of processes in EMDR trauma therapy, the Processing Difficulties Scale (PDS). This scale includes 17 items described by experienced EMDR consultants and practitioners as indicative of problems during memory reprocessing. The proposed factorial solution based on four factors explains a total variance explained of 55% and an adequate goodness of fit, based on the proposed indices: RMSEA = 0.07; TLI = 0.91; CFI = 0.95. Table 1 shows the factorial loads for each of the items. The first factor includes 5 items (7, 8, 9, 10, 11), the second factor includes 6 items (13, 14, 25, 27, 28, 31), the third factor includes 3 items (3, 16, 22) and the fourth factor includes 3 items (19, 23, 24). Confirmatory analysis confirms the factorial solution proposed in the exploratory analysis factor and based on four factors with 17 items. The analysis of internal consistency from Cronbach's alpha and the Omega index shows good internal consistency: Factor 1 (good processing; α = 0.92; ω = 0.94), Factor 2 (lack of generalization and/or absence of changes; α = 0.87; ω = 0.90), Factor 3 (poor emotional processing; α = 0.83; ω = 0.85) an Factor 4 (loss of dual attention; α = 0.82; ω = 0.83). In the case of the total scale, both coefficients exceeded 0.90, with an alpha of 0.92 and an Omega of 0.94. The convergent and discriminant validity criteria were estimated by calculating correlations, exploring the relationship between the factors resulting from the final result, the global severity index (GSI) of the SCL-90 and the level of improvement (NGS). These statistical analyses showed good levels of convergent and discriminant validity for all final factors. The PDS may offer a different perspective to analyze the controversy between clinicians and researchers about the need of a preparation phase in patients with complex early traumatization, dissociative symptoms and/or emotion dysregulation, and the different results in specific research around this topic. Exploring the problems in processing in a transdiagnostic way, in a preliminary analysis, we found that the number of early traumatic events measured with the ACE correlates positively with indicators of a loss of dual attention, while emotional dysregulation measured with the DERS does not predict poor processing. Finally, the dissociation measured with the DES seems to correlate positively with the indicators of a loss of dual attention during processing, not seeming to predict poor processing but did show a negative correlation with the indicators of good general processing. These results partially support the findings of some authors on the involvement of certain variables in the processing of traumatic memories, and it may be interesting to evaluate processing styles and their relationship with various indicators, to develop specific interventions in phase 2 of EMDR therapy, thus improving clinical interventions.

Survival, Attachment, and Healing: An Evolutionary Lens on Interventions for Trauma-Related Dissociation

Purpose

Dissociation is a necessary part of our threat response system, common to all animal species, normally temporarily activated under conditions of extreme or inescapable threat. Pathological dissociation, however, continues to occur after the initial threat has passed, in response to reminders or inaccessibility of safety and security. Present across the spectrum of psychiatric diagnoses, recurrent dissociative symptoms are linked to severe trauma exposure, insecure attachment, treatment non-response, and maladaptive coping behaviors such as substance use, suicidality, and self-harm. However, empirical studies testing treatments specific to dissociative processes remain scarce. This narrative review summarizes existing studies and provides theoretical, neurobiological, and evolutionary perspectives on dissociative processes and treatments for pathological dissociation.

Methods

A systematic search of five databases (MEDLINE, EMBASE, APA PsycINFO, CINAHL plus, Scopus) was conducted on April 13, 2023. Peer-reviewed clinical studies with adult participants, assessing intervention effects on dissociative symptoms, were included. Results were thematically analyzed and summarized.

Results

Sixty-nine studies were identified, mainly focused on posttraumatic stress disorder, trauma-exposed populations, and borderline personality disorder. Psychotherapy was studied in 72.5% of studies; other interventions included medications and neurostimulation. The majority reported positive outcomes, despite the heterogeneous spectrum of interventions. However, treatment of dissociative symptoms was the primary objective in only a minority.

Conclusion

Pathological dissociation is a complex phenomenon involving brain and body systems designed for perceiving and responding to severe threats, requiring an individualized approach. A literature is emerging regarding potentially evidence-based treatments to help those impacted by recurrent dissociative symptoms. When contextualized within a neurobiological and evolutionary perspective, these treatments can be understood as facilitating an internal and/or relational sense of safety, resulting in symptom reduction. Further studies are needed to explore effective treatments for dissociative symptoms.

Exhausting, but necessary: the lived experience of participants in an intensive inpatient trauma treatment program

Background

Intensive inpatient treatment programs have shown robust results in the treatment of post-traumatic stress disorder (PTSD). How patients experience this treatment program and what changes they experience as a result of the treatment have, however, only scarcely been explored through qualitative studies.

Objective

This study aimed to explore the lived experience of participants in an intensive inpatient trauma treatment program. Our research questions were as follows: how do patients experience intensive trauma-focused treatment? How do they experience possible changes related to participating in the treatment program?

Methods

Six patients diagnosed with PTSD with significant comorbidities, who recently participated in an intensive 2-week (4 + 4 days) inpatient trauma treatment program with prolonged exposure (PE), eye movement desensitization and reprocessing (EMDR), and therapist rotation (TR), were interviewed with a semi-structured qualitative interview. Transcripts were analyzed using a thematic analysis approach.

Results

Our analysis resulted in five main themes: (1) the need to feel safe; (2) the benefits of many and different therapeutic encounters; (3) variable experience with elements of treatment; (4) intensity; and (5) experienced change. Our results suggest that feeling safe within the framework of the treatment program facilitated the treatment process. Many and different therapeutic encounters, both through TR and with ward staff, contributed to experienced change. All participants described the intensity as facilitative to trauma processing. However, most participants also describe often feeling too overwhelmed to benefit from all elements of the treatment program.

Conclusions

Our findings suggest that participants experience the overall treatment program as beneficial and contributing to experienced change. Participants described the intensity of the program as exhausting, but necessary. Most did, however, report at times of being too overwhelmed to benefit from elements of the program. Consequently, our results prompt us to question the optimal level of intensity.

Trauma-focused treatment of a client with Complex PTSD and comorbid pathology using EMDR therapy

OBJECTIVE

Complex post-traumatic stress disorder (CPTSD) is a classification within the International Classification of Diseases, 11th Revision (ICD-11) that, besides the DSM-5 symptom clusters of post-post-traumatic stress disorder (PTSD), includes the presence of negative self-concept, difficulties in regulating emotions and relationship skills. The purpose of the present study was to provide guidance on how to deliver Eye Movement Desensitization and Reprocessing (EMDR) therapy in the context of CPTSD, based on current clinical knowledge and the latest scientific research findings.

METHOD

This paper describes the treatment of a 52-year-old woman with CPTSD and borderline personality disorder for which immediate trauma-focused EMDR therapy was used.

RESULTS

First, a description of what EMDR therapy entails and some important treatment strategies that the therapist may employ to assist in trauma-focused treatment of clients with CPTSD using EMDR therapy are outlined.

CONCLUSION

The treatment results are in line with mounting evidence supporting the notion that EMDR therapy is a safe and potentially effective treatment alternative for individuals with CPTSD or personality problems.

Treatment of Posttraumatic Stress Disorder: A State-of-the-art Review

This narrative state-of-the-art review paper describes the progress in the understanding and treatment of Posttraumatic Stress Disorder (PTSD). Over the last four decades, the scientific landscape has matured, with many interdisciplinary contributions to understanding its diagnosis, etiology, and epidemiology. Advances in genetics, neurobiology, stress pathophysiology, and brain imaging have made it apparent that chronic PTSD is a systemic disorder with high allostatic load. The current state of PTSD treatment includes a wide variety of pharmacological and psychotherapeutic approaches, of which many are evidence-based. However, the myriad challenges inherent in the disorder, such as individual and systemic barriers to good treatment outcome, comorbidity, emotional dysregulation, suicidality, dissociation, substance use, and trauma-related guilt and shame, often render treatment response suboptimal. These challenges are discussed as drivers for emerging novel treatment approaches, including early interventions in the Golden Hours, pharmacological and psychotherapeutic interventions, medication augmentation interventions, the use of psychedelics, as well as interventions targeting the brain and nervous system. All of this aims to improve symptom relief and clinical outcomes. Finally, a phase orientation to treatment is recognized as a tool to strategize treatment of the disorder, and position interventions in step with the progression of the pathophysiology. Revisions to guidelines and systems of care will be needed to incorporate innovative treatments as evidence emerges and they become mainstream. This generation is well-positioned to address the devastating and often chronic disabling impact of traumatic stress events through holistic, cutting-edge clinical efforts and interdisciplinary research.

The role of dissociation-related beliefs about memory in trauma-focused treatment

OBJECTIVE

Dysfunctional cognitions play a central role in the development of post-traumatic stress disorder (PTSD). However the role of specific dissociation-related beliefs about memory has not been previously investigated. This study aimed to investigate the role of dissociation-related beliefs about memory in trauma-focused treatment. It was hypothesized that patients with the dissociative subtype of PTSD would show higher levels of dissociation-related beliefs, dissociation-related beliefs about memory would decrease after trauma-focused treatment, and higher pre-treatment dissociation-related beliefs would be associated with fewer changes in PTSD symptoms.

METHOD

Post-traumatic symptoms, dissociative symptoms, and dissociation-related beliefs about memory were assessed in a sample of patients diagnosed with PTSD (n = 111) or the dissociative subtype of PTSD (n = 61). They underwent intensive trauma-focused treatment consisting of four or eight consecutive treatment days. On each treatment day, patients received 90 min of individual prolonged exposure (PE) in the morning and 90 min of individual eye movement desensitization and reprocessing (EMDR) therapy in the afternoon. The relationship between dissociation-related beliefs about memory and the effects of trauma-focused treatment was investigated.

RESULTS

Dissociation-related beliefs about memory were significantly associated with PTSD and its dissociative symptoms. In addition, consistent with our hypothesis, patients with the dissociative subtype of PTSD scored significantly higher on dissociation-related beliefs about memory pre-treatment than those without the dissociative subtype. Additionally, the severity of these beliefs decreased significantly after trauma-related treatment. Contrary to our hypothesis, elevated dissociation-related beliefs did not negatively influence treatment outcome.

CONCLUSION

The results of the current study suggest that dissociation-related beliefs do not influence the outcome of trauma-focused treatment, and that trauma-focused treatment does not need to be altered specifically for patients experiencing more dissociation-related beliefs about memory because these beliefs decrease in association with treatment.

Inhibition, Attentional Control and Binding Abilities in Relation to Dissociative Symptoms Among PTSD Patients

INTRODUCTION

The relationship between dissociation and cognitive abilities remains controversial. Empirical studies have reported positive, negative and non-existent associations between dissociation and cognition. These inconsistent results may be due to the fact that the studies focused mainly on trait dissociation, while dissociation is not stable but transient. After validating the French version of the Clinician Administered Dissociative States Scale (CADSS), the aim of the present study was to evaluate the relationship between state dissociation and cognitive abilities.

METHOD

We recruited 83 patients suffering from post-traumatic stress disorder (PTSD) and assessed them twice. At T1, they performed a neutral Stroop task and a neutral binding task. At T2 (one to three weeks later), after a script-driven dissociative induction, they performed an emotional Stroop task and an emotional binding task. Between the two sessions, they completed questionnaires at home evaluating PTSD severity, trait dissociation and cognitive difficulties. State dissociation was assessed at T1 and T2 using the Clinician-Administered Dissociative States Scale (CADSS).

RESULTS

We found good psychometric properties of the French version of the CADSS. After inducing dissociation, significantly lower attentional performance was found among patients with than without dissociative reactions. We found a significant positive correlation between state dissociation and increased attention and memory difficulties after induction.

CONCLUSION

The French version of the CADSS is a reliable and valid tool to assess state dissociation, which is correlated with attentional difficulties. Attentional training is recommended to help patients control dissociative symptoms.

Impact of dissociation on exposure therapy for PTSD outcomes and Adherence among U.S. Military service members

Emotional engagement is necessary for successful exposure therapy for posttraumatic stress disorder (PTSD), but dissociation is considered a barrier to emotional engagement. Virtual reality exposure therapy (VRE) uses multi-sensory virtual environments to increase emotional engagement during exposure therapy, and average treatment outcomes are comparable to traditional exposure therapy. However, individual factors (e.g., depression) can predict differential responses to VRE. Studies have yet to investigate whether VRE would be more effective in treating patients with dissociation compared to traditional PE. This secondary analysis of a randomized clinical trial explores whether dissociation predicts treatment outcomes to exposure therapy among active-duty soldiers (N = 108) diagnosed with PTSD. We also examine whether individuals reporting dissociative symptoms demonstrated differential treatment responses to VRE and PE. Results indicated a significant two-way interaction between dissociation and time in treatment, such that dissociation blunted the negative relationship between time and PTSD symptoms. Dissociation was not associated with treatment session attendance or drop out. Results also revealed no significant effect of treatment group (PE or VRE) on the relationship between dissociation and PTSD symptoms. Findings contribute to a body of literature supporting the potential clinical and research utility of a dissociative subtype of PTSD.

Neurobiological and genetic correlates of the dissociative subtype of posttraumatic stress disorder

Approximately 10%-30% of individuals with posttraumatic stress disorder (PTSD) exhibit a dissociative subtype of the condition defined by symptoms of depersonalization and derealization. This study examined the psychometric evidence for the dissociative subtype of PTSD in a sample of young, primarily male post-9/11-era Veterans (n = 374 at baseline and n = 163 at follow-up) and evaluated its biological correlates with respect to resting state functional connectivity (default mode network [DMN]; n = 275), brain morphology (hippocampal subfield volume and cortical thickness; n = 280), neurocognitive functioning (n = 337), and genetic variation (n = 193). Multivariate analyses of PTSD and dissociation items suggested a class structure was superior to dimensional and hybrid ones, with 7.5% of the sample comprising the dissociative class; this group showed stability over 1.5 years. Covarying for age, sex, and PTSD severity, linear regression models revealed that derealization/depersonalization severity was associated with: decreased DMN connectivity between bilateral posterior cingulate cortex and right isthmus (p = .015; adjusted-p [padj] = .097); increased bilateral whole hippocampal, hippocampal head, and molecular layer head volume (p = .010-.034; padj = .032-.053); worse self-monitoring (p = .018; padj = .079); and a candidate genetic variant (rs263232) in the adenylyl cyclase 8 gene (p = .026), previously associated with dissociation. Results converged on biological structures and systems implicated in sensory integration, the neural representation of spatial awareness, and stress-related spatial learning and memory, suggesting possible mechanisms underlying the dissociative subtype of PTSD.

Omitting continuous memory recall from dual-task interventions does not reduce intervention effectiveness

In Eye Movement Desensitization and Reprocessing a patient recalls a traumatic memory, while simultaneously performing a dual-task (e.g., making horizontal eye movements, tapping a pattern). Earlier lab studies show that increasing the load of a dual-task -and leaving fewer resources for memory recall-results in larger decreases in memory vividness and emotionality compared to control conditions. Therefore, we investigated whether it is necessary to continuously and deliberately recall the memory next to performing high taxing dual-tasks. In two online experiments, participants (N = 172, N = 198) recalled a negative autobiographical memory and were randomly assigned to (1) Memory Recall + Dual-Tasks, (2) Dual-Tasks Only, or (3) No Intervention Control. The dual-tasks were complex pattern tapping and spelling out loud. Before and after the intervention the memory was rated on vividness, emotionality, and accessibility. High taxing dual-tasks, regardless of whether there was continuous memory recall, resulted in the largest reductions in all dependent variables compared to control. Unexpectedly, there was no evidence that the addition of continuous memory recall added to these reductions. These results suggest that continuous memory recall might not, or only minimally be needed for the beneficial effects of the dual-task procedure in EMDR might not be beneficial per se. We discuss the necessity of memory (re)activation, alternative explanations, and implications for practice.

If it's offered, will they come? Practical considerations when offering intensive PTSD treatment in an outpatient Veterans Affairs PTSD clinic

Evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD) are efficacious; however, treatment dropout remains high. The delivery of intensive EBPs for PTSD (i.e., sessions three times per week or more) and telemental health may address barriers impacting dropout. Current evidence for intensive EBPs comes primarily from programs specifically designed for this level of care. Therefore, the feasibility of delivering intensive EBPs for PTSD in traditional outpatient clinics remains unclear. The aim of this pilot study was to identify veteran level of interest in intensive treatment and explore the feasibility of delivering intensive treatment via telemental health in an outpatient PTSD clinic at a Veterans Affairs (VA) hospital. One provider offered intensive treatment to 14 veterans. Three of the veterans initiated intensive treatment and completed with benefit. Veteranand system-level barriers, as well as veteran preferences for initiating intensive therapy and suggestions for implementing intensive EBPs in a routine outpatient clinic, are discussed.

The PTSD Symptom Presentation and the Effect of Polytrauma on PTSD Symptom Clusters Among Young People Who Have Experienced Commercial Sexual Exploitation and Trafficking

Purpose

The purpose of this study was to describe the PTSD symptom presentation (including dissociative symptoms) of PTSD using the Diagnostic and Statistical Manual of Mental Disorders 5 th Edition diagnostic criteria and explore associations between the symptom severity for each of the four PTSD symptom clusters and polytrauma, defined as multiple exposures to different categories of potentially traumatic events.

Methods

This is a secondary analysis of cross-sectional program evaluation data among 95 young people (aged 11-19) at therapy initiation in a southeastern state in the U.S. We used descriptive statistics and multivariable linear regression to test study objectives.

Results

Eighty-one respondents (90.0%) experienced a potentially traumatic event in ≥ 2 trauma categories, in addition to experiencing CSE/T. Approximately two-thirds of respondents experienced clinically significant PTSD symptoms for each symptom cluster. Of the 31 young people who met full criteria for PTSD, 9 met criteria for the standard PTSD diagnosis, while 22 met criteria for the dissociative subtype of PTSD. On average, experiencing additional trauma categories was associated with substantively higher PTSD symptom cluster scores for each cluster.

Conclusions

These findings support the need for a comprehensive assessment of trauma symptoms that includes cluster-specific PTSD symptoms. They also underscore the need to assess the full breadth and chronicity of trauma experiences to guide treatment planning and delivery, targeting specific domains of trauma impact. These findings can also inform the tailoring and adaptation of evidence-based interventions and strategies to better meet the needs of young people who have experienced CSE/T.

Factor Structure and Clinical Correlates of The Dissociative Symptoms Scale (DSS) Korean Version Among Community Sample With Adverse Childhood Experiences

This study examined the factor structure and psychometric properties of the Dissociative Symptoms Scale (DSS) among the Korean community adult population with adverse childhood experiences (ACE). Data were drawn from community sample data sets collected from an online panel investigating the impact of ACE and ultimately consisted of data from a total of 1304 participants. A confirmatory factor analysis revealed a bi-factor model with a general factor and four sub-factors such as depersonalization/derealization, gaps in awareness and memory, sensory misperceptions, and cognitive behavioral reexperiencing, which are the four factors that correspond to the original DSS. The DSS showed good internal consistency as well as convergent validity with clinical correlates such as posttraumatic stress disorder, somatoform dissociation, and emotion dysregulation. The high-risk group with more ACE was associated with increased DSS. These findings support the multidimensionality of dissociation and the validity of Korean DSS scores in a general population sample.

A randomized controlled trial of Deep Brain Reorienting: a neuroscientifically guided treatment for post-traumatic stress disorder

BACKGROUND

Advanced neuroscientific insights surrounding post-traumatic stress disorder (PTSD) and its associated symptomatology should beget psychotherapeutic treatments that integrate these insights into practice. Deep Brain Reorienting (DBR) is a neuroscientifically-guided psychotherapeutic intervention that targets the brainstem-level neurophysiological sequence that transpired during a traumatic event. Given that contemporary treatments have non-response rates of up to 50% and high drop-out rates of >18%, DBR is investigated as a putative candidate for effective treatment of some individuals with PTSD.

OBJECTIVE

To conduct an interim evaluation of the effectiveness of an eight-session clinical trial of videoconference-based DBR versus waitlist (WL) control for individuals with PTSD.

METHOD

Fifty-four individuals with PTSD were randomly assigned to DBR (N = 29) or WL (N = 25). At baseline, post-treatment, and three-month follow-up, participants' PTSD symptom severity was assessed using the Clinician Administered PTSD Scale (CAPS-5). This is an interim analysis of a clinical trial registered with the U. S. National Institute of Health (NCT04317820).

RESULTS

Significant between-group differences in CAPS-total and all subscale scores (re-experiencing, avoidance, negative alterations in cognitions/mood, alterations in arousal/reactivity) were found at post-treatment (CAPS-total: Cohen's d = 1.17) and 3-month-follow-up (3MFU) (CAPS-total: Cohen's d = 1.18). Significant decreases in CAPS-total and all subscale scores were observed within the DBR group pre - to post-treatment (36.6% CAPS-total reduction) and pre-treatment to 3MFU (48.6% CAPS-total reduction), whereas no significant decreases occurred in the WL group. After DBR, 48.3% at post-treatment and 52.0% at 3MFU no longer met PTSD criteria. Attrition was minimal with one participant not completing treatment; eight participants were lost to 3MFU.

CONCLUSIONS

These findings provide emerging evidence for the effectiveness of DBR as a well-tolerated treatment that is based on theoretical advances highlighting alterations to subcortical mechanisms in PTSD and associated symptomatology. Additional research utilizing larger sample sizes, neuroimaging data, and comparisons or adjacencies with other psychotherapeutic approaches is warranted.Trial registration: ClinicalTrials.gov identifier: NCT04317820..

Efficacy of traumatic memory reactivation with or without propranolol in PTSD with high dissociative experiences

Background: Post-traumatic stress disorder (PTSD) with dissociative symptoms is now a full-fledged subtype of this disorder. The dissociative subtype is associated with a greater number of psychiatric comorbidities. To date, the impact of dissociation on the efficacy of PTSD treatment remains unclear.Objective: The aim of this study was to compare the efficacy of a traumatic memory reactivation procedure with the administration of propranolol or a placebo once a week for six consecutive weeks in reducing PTSD and MDE symptoms between PTSD subjects with or without high dissociative symptoms.Method: For that, we conducted a randomized clinical trial in 66 adults diagnosed with longstanding PTSD and measured the SCID PTSD module, the PTSD Checklist (PCL-S), Beck's Depression Inventory-II (BDI-II), and the Dissociative Experiences Scale (DES).Results: Patients with and without high dissociative experience had significant improvement in their PCL-S scores over the 6 treatment sessions, and PCL-S scores continued to decline in all patients during the post-treatment period. However, there was no correlation between the presence/absence of high dissociative experiences and no specific effect of propranolol treatment. We found exactly the same results for MDE symptoms. Interestingly, patients with high dissociative experiences before treatment exhibited very significant improvement in their DES scores after the 6 treatment sessions, and patients maintained this improvement 3 months post-treatment.Conclusions: The traumatic memory reactivation procedure is an effective way to treat dissociative symptoms in patients with PTSD, and improvement of these dissociative symptoms was associated with a decrease in both PTSD and depression severity.

The brain-body disconnect: A somatic sensory basis for trauma-related disorders

Although the manifestation of trauma in the body is a phenomenon well-endorsed by clinicians and traumatized individuals, the neurobiological underpinnings of this manifestation remain unclear. The notion of somatic sensory processing, which encompasses vestibular and somatosensory processing and relates to the sensory systems concerned with how the physical body exists in and relates to physical space, is introduced as a major contributor to overall regulatory, social-emotional, and self-referential functioning. From a phylogenetically and ontogenetically informed perspective, trauma-related symptomology is conceptualized to be grounded in brainstem-level somatic sensory processing dysfunction and its cascading influences on physiological arousal modulation, affect regulation, and higher-order capacities. Lastly, we introduce a novel hierarchical model bridging somatic sensory processes with limbic and neocortical mechanisms regulating an individual's emotional experience and sense of a relational, agentive self. This model provides a working framework for the neurobiologically informed assessment and treatment of trauma-related conditions from a somatic sensory processing perspective.

Fully remote intensive trauma-focused treatment for PTSD and Complex PTSD

Background: It is unknown whether remotely delivered intensive trauma-focused therapy not only is an effective treatment for PTSD, but also for Complex PTSD. Objective: Testing the hypothesis that a brief, fully remotely administered intensive trauma-focused treatment programme for individuals with PTSD and Complex PTSD would be safe, and associated with a significant decline of the corresponding symptoms and diagnostic status. Method: The treatment sample consisted of 73 consecutive patients diagnosed with PTSD according to the CAPS-5. According to the ITQ (n = 70) 33 (47.1%) patients also fulfilled the diagnostic criteria of Complex PTSD. The 4-day treatment programme contained a combination of prolonged exposure, EMDR therapy, physical activities and psycho-education. Treatment response was measured using the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), the PTSD Checklist for DSM-5 (PCL-5), and the International Trauma Questionnaire (ITQ) for classifying Complex PTSD and indexing disturbances in self-organization (DSO). Results: Overall CAPS-5, PCL-5, and ITQ-DSO scores decreased significantly from pre- to post-treatment (Cohen's ds 2.12, 1.59, and 1.18, respectively), while the decrease was maintained to six months follow-up. At post-treatment, 60 patients (82.2%) no longer met the diagnostic criteria of PTSD, while the proportion of patients with Complex PTSD decreased from 47.1% to 10.1%. No drop out, and no personal adverse events occurred. Conclusions: The results support the notion that intensive, trauma-focused treatment is feasible, safe and associated with a large decrease in PTSD and Complex PTSD symptoms, even when it is brief, and applied fully remote. HIGHLIGHTS Second study to examine the effectiveness of a fully remote intensive trauma-focused treatment for PTSD and Complex PTSD.Significant decrease of DSO symptoms.Over 80 percent of the patients no longer met the diagnostic criteria of PTSD and Complex PTSD following treatment.

Prevalence of the dissociative subtype of post-traumatic stress disorder: a systematic review and meta-analysis

The dissociative subtype of post-traumatic stress disorder (PTSD-DS) was introduced in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and is characterised by symptoms of either depersonalisation or derealisation, in addition to a diagnosis of post-traumatic stress disorder (PTSD). This systematic review and meta-analysis sought to estimate the point prevalence of current PTSD-DS, and the extent to which method of assessment, demographic and trauma variables moderate this estimate, across different methods of prevalence estimation. Studies included were identified by searching MEDLINE (EBSCO), PsycInfo, CINAHL, Academic Search Complete and PTSDpubs, yielding 49 studies that met the inclusion criteria (N = 8214 participants). A random-effects meta-analysis estimated the prevalence of PTSD-DS as 38.1% (95% CI 31.5-45.0%) across all samples, 45.5% (95% CI 37.7-53.4%) across all diagnosis-based and clinical cut-off samples, 22.8% (95% CI 14.8-32.0%) across all latent class analysis (LCA) and latent profile analysis (LPA) samples and 48.1% (95% CI 35.0-61.3%) across samples which strictly used the DSM-5 PTSD criteria; all as a proportion of those already with a diagnosis of PTSD. All results were characterised by high levels of heterogeneity, limiting generalisability. Moderator analyses mostly failed to identify sources of heterogeneity. PTSD-DS was more prevalent in children compared to adults, and in diagnosis-based and clinical cut-off samples compared to LCA and LPA samples. Risk of bias was not significantly related to prevalence estimates. The implications of these results are discussed further.

Negative effects during multicomponent group-based treatment: A multisite study

Objective Negative effects (NEs) in group treatments remain an under-researched area. This study aimed to explore the prevalence of various types of NEs in a multicomponent group-based treatment and to determine their predictors. Method: A total of 330 patients participating in a multicomponent group-based treatment were recruited across seven clinical sites. At the end of treatment, the Negative Effects Questionnaire (NEQ) was used to measure NEs. Item-level descriptive analysis was conducted to explore the prevalence of various types of NEs, and structural equation modeling was used to determine predictors of these NEs. Results: The most frequently reported type of NEs was the worsening of symptoms, and the single most frequently reported item was the resurfacing of unpleasant memories. Predictors of NEs included the overall distress level, alexithymia, attachment avoidance, low working alliance, problem actuation, and worse outcomes; psychological mindedness was a protective factor. Conclusion: Patients who experience higher levels of distress at the beginning of treatment, who perceive the group working alliance as problematic, and who experience high in-session emotional arousal related to their problem seem to be especially prone to reporting NEs. Furthermore, the findings do not support the assumption that NEs are a prerequisite for therapeutic change.Trial registration: ISRCTN.org identifier: ISRCTN13532466.

A systematic review and meta-analysis of psychological interventions for comorbid post-traumatic stress disorder and substance use disorder

Background

The psychological treatment of comorbid post-traumatic stress disorder (PTSD) and substance use disorder (SUD) is clinically challenging, and outcomes are often poor.

Objective

This paper describes a systematic review and meta-analysis which sought to establish the current efficacy for a number of established psychological approaches for adults and adolescents, in comparison to interventions for SUD alone, or other active approaches, following a pre-registered protocol.

Method

This review followed PRISMA and Cochrane Collaboration guidelines. Data extraction and risk of bias judgements using Cochrane criteria were undertaken by all authors. Primary outcomes were PTSD severity and substance use post-treatment. The quality of findings was assessed using GRADE. Following a comprehensive search, conducted to 13 September 2021, 27 studies were included.

Results

We found a relatively high level of dropout across studies. In our main comparisons, we found no benefits for present-focused treatment approaches aimed at improving coping skills beyond those for SUD-only interventions. We found modest benefits for trauma-focused intervention plus SUD intervention post-treatment for PTSD (standardized mean difference (SMD) = -0.36, 95% confidence interval (CI) -0.64, -0.08), and at 6-13 months for PTSD (SMD = -0.48, 95% CI -0.81, -0.15) and alcohol use (SMD = -0.23, 95% CI -0.44, -0.02). There were no benefits for cognitive restructuring interventions as a group, but we found a modest effect for integrated cognitive behavioural therapy (ICBT) for PTSD post-treatment (SMD = -0.33, 95% CI -0.62, -0.04). There was evidence of some benefit for trauma-focused intervention over present-focused intervention for PTSD from a single study and for reduction in dropout for incentivized attendance for trauma-focused intervention from another single study. Most findings were of very low quality.

Conclusion

There is evidence that trauma-focused therapy and ICBT can improve PTSD for some individuals, but many patients do not fully engage with treatment and average treatment effects are modest.

HIGHLIGHTS

For PTSD, evidence was strongest for trauma-focused CBT-based approaches, but effects were modest.There was little evidence of any added benefit on substance use, beyond that of standard addiction treatments, for any included intervention.Dropout from treatment was high.

Beyond the DES-II

The Dissociative Experiences Scale (DES-II) remains the most widely used brief screening tool for identifying dissociative symptoms despite limitations of the instrument and the training of those who use it. Standard eye movement desensitization and reprocessing (EMDR) therapy procedures require a thorough clinical assessment and formally screening for the presence of a dissociative disorder. This aids development of an accurate case conceptualization prior to the preparation and trauma reprocessing phases of EMDR therapy. Reliance on DES-II mean scores as the sole measure of dissociative features—particularly with persons reporting a history of early childhood neglect or abuse—is insufficient to determine readiness for safely reprocessing traumatic memories. The International Society for the Study of Trauma and Dissociation (ISSTD) Guidelines for Treating Dissociative Identity Disorder in Adults, Third Revision, noted that employing standard EMDR therapy with individuals suffering from an unrecognized dissociative disorder was reported as a risk for significant harm. EMDR-trained clinicians’ standard practice of screening for dissociative disorders must evolve beyond a casual reliance upon the DES-II. Consistent use of a mental status examination and reliable diagnostic tools is needed. Several relevant assessment tools are reviewed with their strengths and limitations. The authors recommend that clinicians apply these approaches even when their intent is to screen out persons whose presenting difficulties lie outside their scope of practice or research design.

Augmenting PTSD treatment with physical activity: study protocol of the APPART study (Augmentation for PTSD with Physical Activity in a Randomized Trial)

BACKGROUND

New intensive trauma-focused treatment (TFT) programmes that incorporate physical activity have been developed for people with post-traumatic stress disorder (PTSD). However, the unique contribution of physical activity within these intensive TFT programmes has never been investigated in a controlled manner.

OBJECTIVES

This randomized controlled trial will investigate the effectiveness of physical activity added to an intensive TFT programme. In addition, the study aims to investigate the underlying mechanisms of the effects of physical activity on the change in PTSD symptoms.

METHODS

Individuals with PTSD (N = 120) will be randomly allocated to two conditions: a physical activity or a non-physical active control condition. All participants will receive the same intensive TFT lasting eight days within two consecutive weeks, in which daily prolonged exposure and EMDR therapy sessions, and psycho-education are combined. The amount of physical activity will differ per condition. While the physical activity condition induces daily physical activities with moderate intensity, in the non-physical active control condition no physical activity is prescribed; but instead, a controlled mixture of guided (creative) tasks is performed. The two primary outcome measures are change in PTSD symptoms from pre- to post-treatment and at six months follow-up, measured with the Clinician-Administered PTSD Scale (CAPS-5), and the PTSD Checklist for DSM-5 (PCL-5). Additionally, self-reported sleep problems, depressive symptoms, emotion regulation, dissociation symptoms and anxiety sensitivity will be measured as potential underlying mechanisms.

CONCLUSIONS

This study will contribute to the research field of augmentation strategies for PTSD treatment by investigating the effectiveness of physical activity added to intensive TFT.

TRIAL REGISTRATION

This trial is registered in the Netherlands Trial Register (Trial NL9120).

The dissociative subtype of PTSD in trauma-exposed individuals: a latent class analysis and examination of clinical covariates

BACKGROUND

A dissociative subtype of posttraumatic stress disorder (D-PTSD) was introduced into the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) but latent profiles and clinical correlates of D-PTSD remain controversial.

OBJECTIVE

The aims of our study were to identify subgroups of individuals with distinct patterns of PTSD symptoms, including dissociative symptoms, by means of latent class analyses (LCA), to compare these results with the categorization of D-PTSD vs. PTSD without dissociative features according to the CAPS-5 interview, and to explore whether D-PTSD is associated with higher PTSD severity, difficulties in emotion regulation, and depressive symptoms.

METHOD

A German sample of treatment-seeking individuals was investigated (N = 352). We conducted an LCA on the basis of symptoms of PTSD and dissociation as assessed by the CAPS-5. Moreover, severity of PTSD (PCL-5), difficulties in emotion regulation (DERS), and depressive symptoms (BDI-II) were compared between patients with D-PTSD according to the CAPS-5 interview and patients without dissociative symptoms.

RESULTS

LCA results suggested a 5-class model with one subgroup showing the highest probability to fulfill criteria for the dissociative subtype and high scores on both BDI and DERS. Significantly higher scores on the DERS, BDI and PCL-5 were found in the D-PTSD group diagnosed with the CAPS-5 (n = 75; 35.7%). Sexual trauma was also reported more often by this subgroup. When comparing the dissociative subtype to the LCA results, only a partial overlap could be found.

CONCLUSIONS

Our findings suggest that patients with D-PTSD have significantly more problems with emotion regulation, more depressive symptoms, and more severe PTSD-symptoms. Given the results of our LCA, we conclude that the dissociative subtype seems to be more complex than D-PTSD as diagnosed by means of the CAPS-5.

Intensive outpatient treatment for PTSD: an open trial combining prolonged exposure therapy, EMDR, and physical activity

Background: Intensive outpatient treatment could be a promising option for patients with post-traumatic stress disorder (PTSD). Objective: The aim of the study was to test the effectiveness of an eight-day (two-week) intensive treatment for PTSD within a public health care setting (open trial design). Method: Eighty-nine patients were offered the choice between intensive treatment and spaced individual treatment, of which 34 (38.2%) chose the intensive format. Patients were assessed with self-report batteries and interviews at pre-treatment, start of treatment, post-treatment and three-month follow-up. Each day consisted of individual Prolonged Exposure therapy, Eye Movement Desensitization and Reprocessing therapy, group psychoeducation, and physical activity. Therapists rotated between patients. Results: Between 55 and 62% of the patients showed a clinically significant change (recovery) in symptoms of PTSD, and the effect sizes were large (d = 1.38-1.52). Patients also showed reduction in symptoms of depression and anxiety, along with improved well-being and interpersonal functioning. Changes in social and work functioning were more ambiguous. There were no dropouts, attendance was high, and patients were highly satisfied with the treatment. Conclusions: The intensive programme was an attractive and effective treatment option for patients with PTSD.

A brief cognitive-behavioural treatment approach for PTSD and Dissociative Identity Disorder, a case report

BACKGROUND AND OBJECTIVES

We described a new treatment model for Posttraumatic Stress Disorder (PTSD) and Dissociative Identity Disorder (DID), based on cognitive-behavioural principles. In this model, dissociation is seen as a maladaptive avoidant coping strategy. In addition, we stress that patients have dysfunctional beliefs about dissociation. Both elements, avoidance behaviour and dysfunctional beliefs, are challenged during the brief, intensive trauma-focused treatment. When the PTSD-symptoms decrease, the patient is offered a fare-well ritual to say goodbye to their identities in one or more additional sessions.

METHODS

We illustrate this treatment approach with a case report of a woman with PTSD as a result of sexual abuse in her childhood, and DID with four identities. Treatment outcome was measured at intake, at pre-treatment, at post-treatment and at 3 and 6 months follow-up.

RESULTS

After the short treatment of only 2 weeks, she no longer fulfilled the DSM-5 diagnostic criteria for PTSD nor DID. These results were maintained at the follow-ups.

LIMITATIONS

Although we included a baseline-controlled time phase, it was not a controlled study, and only one patient was treated.

CONCLUSIONS

This new treatment model for DID-patients is promising but results should be interpreted cautiously since we described only one patient.

Intensive outpatient treatment for PTSD: a pilot feasibility study combining prolonged exposure therapy, EMDR, physical activity, and psychoeducation

Background: Intensive treatment could be effective for patients with post-traumatic stress disorder (PTSD). Objective: The aim of the study was to test the feasibility of an 8-day (2-week) intensive outpatient treatment for PTSD. Method: Treatment each day consisted of individual Prolonged Exposure (PE), Eye Movement Desensitization and Reprocessing (EMDR), and psychoeducation and physical activity in groups. Patients met different therapists from session to session. Results: Six patients started and completed treatment. Levels of attendance of sessions was high. Patients reported that they were satisfied with the treatment, describing it as emotionally taxing, but meaningful. Therapists also described several positive aspects of the treatment format. There were large reductions in PTSD symptoms. Conclusions: Given these promising, but preliminary findings on the programme's feasibility, future research should investigate this treatment format using larger samples and controlled designs.

Somatoform Dissociative Symptoms Have No Impact on the Outcome of Trauma-Focused Treatment for Severe PTSD

For patients with complex or other severe forms of PTSD, particularly in cases with dissociative symptoms, different treatment approaches have been suggested. However, the influence of somatoform dissociation on the effectiveness of trauma-focused treatment has hardly ever been studied. This study aims to test the hypotheses that (1) PTSD patients reporting a low level and those reporting a high level of somatoform dissociative symptoms would both benefit from an intensive trauma-focused treatment, and that (2) somatoform dissociative symptoms would alleviate. Participants were 220 patients with severe PTSD, enrolled in an intensive treatment program combining EMDR therapy and prolonged exposure therapy, without a preceding stabilization phase. Trauma history was diversified, and comorbidity was high. PTSD symptoms (CAPS-5 and PCL-5) and somatoform dissociative symptoms (SDQ-5 and SDQ-20) were assessed at pre-treatment, post-treatment and at six months after completion of treatment. The course of both PTSD and somatoform dissociative symptoms was compared for individuals reporting low and for those reporting high levels of somatoform dissociative symptoms. Large effect sizes were observed regarding PTSD symptoms reduction for patients with both low and high levels of somatoform dissociation. Somatoform dissociation did not impact improvement in terms of PTSD symptom reduction. The severity of somatoform dissociative symptoms decreased significantly in both groups. This decrease was greater for those with a positive screen for a dissociative disorder. These results add further support to the notion that the presence of strong somatoform dissociative symptoms in patients with PTSD does not necessarily call for a different treatment approach. Clinical implications are discussed.

A Systematic Review of Intensive Empirically Supported Treatments for Posttraumatic Stress Disorder

Various clinical practice guidelines for the treatment of posttraumatic stress disorder (PTSD) have consistently identified two frontline evidence-based psychotherapies (EBPs)-prolonged exposure (PE) and cognitive processing therapy (CPT)-as well as other empirically supported treatments (EST), such as eye movement desensitization and reprocessing (EMDR) and cognitive therapy for PTSD (CT for PTSD). However, researchers and clinicians continue to be concerned with rates of symptom improvement and patient dropout within these treatments. Recent attempts to address these issues have resulted in intensive, or "massed," treatments for PTSD. Due to variability among intensive treatments, including treatment delivery format, fidelity to the EST, and the population studied, we conducted a systematic review to summarize and integrate the literature on the impact of intensive treatments on PTSD symptoms. A review of four major databases, with no restrictions regarding publication date, yielded 11 studies that met all inclusion criteria. The individual study findings denoted a large impact of treatment on reduction of PTSD symptoms, ds = 1.15-2.93, and random-effects modeling revealed a large weighted mean effect of treatment, d = 1.57, 95% CI [1.24, 1.91]. Results from intensive treatments also noted high rates of treatment completion (i.e., 0%-13.6% dropout; 5.51% pooled dropout rate across studies). The findings suggest that intensive delivery of these treatments can be an effective alternative to standard delivery and contribute to improved treatment response and reduced treatment dropout.

Sequence matters: Combining Prolonged Exposure and EMDR therapy for PTSD

OBJECTIVE

Investigating the influence of the sequence in which two evidence-based trauma-focused treatments are offered to PTSD-patients.

METHODS

PTSD-patients were treated using an intensive eight-day treatment program, combining Prolonged Exposure (PE) and EMDR therapy. Forty-four patients received a PE session in the morning and an EMDR session in the afternoon, while 62 patients received the reversed sequence (EMDR followed by PE). Outcome measures were PTSD symptom severity and subjective experiences.

RESULTS

Patients who received PE first and EMDR second showed a significantly greater reduction in PTSD symptoms. Patients preferred this sequence and valued the treatment sessions as significantly more helpful compared to patients in the EMDR-first condition.

CONCLUSION

The results of this explorative study are supportive of the notion that PE and EMDR therapy can be successfully combined, and that sequence matters. First applying PE sessions before EMDR sessions resulted in better treatment outcome, and better subjective patient's evaluations in terms of treatment helpfulness and preference.

Trauma-focused treatment outcome for complex PTSD patients: results of an intensive treatment programme

BACKGROUND

Complex PTSD (CPTSD) has been incorporated in the 11th edition of the International Classification of Diseases (ICD-11) as a mental health condition distinct from PTSD.

OBJECTIVE

The objective of the current study is to determine whether individuals classified as having CPTSD can benefit from an intensive trauma-focused treatment, resulting in decreased PTSD and CPTSD symptoms, and loss of diagnoses.

METHOD

Patients diagnosed with PTSD (N = 308) took part in an intensive 8-day treatment programme combining prolonged exposure, EMDR therapy, psycho-education, and physical activity. The treatment was not phase-based in that it did not contain a stabilization phase or skill training prior to therapy. CPTSD diagnosis was assessed by means of the International Trauma Questionnaire (ITQ) and PTSD diagnosis was assessed with both the ITQ and CAPS-5. Treatment response was measured with the CAPS-5, PCL-5, and ITQ.

RESULTS

Symptoms of both PTSD and CPTSD significantly decreased from pre- to post-treatment resulting in a significant loss of CAPS-5 based PTSD (74.0%) and ITQ-based PTSD and CPTSD diagnoses (85.0% and 87.7%, respectively). No adverse events occurred in terms of suicides, suicide attempts, or hospital admissions.

CONCLUSIONS

The results are supportive of the notion that the majority of patients classified as having CPTSD strongly benefit from an intensive trauma-focused treatment for their PTSD.

Impact of dissociation on the effectiveness of psychotherapy for post-traumatic stress disorder: meta-analysis

BACKGROUND

Many patients with post-traumatic stress disorder (PTSD) experience dissociative symptoms. The question of whether these dissociative symptoms negatively influence the effectiveness of psychotherapy for PTSD is unresolved.

AIMS

To determine the influence of dissociative symptoms on psychotherapy outcome in PTSD.

METHOD

We conducted a systematic search in Cochrane, Embase, PILOTS, PsycINFO, PubMed and Web of Science for relevant clinical trials. A random-effects meta-analysis examined the impact of dissociation on psychotherapy outcome in PTSD (pre-registered at Prospero CRD42018086575).

RESULTS

Twenty-one trials (of which nine were randomised controlled trials) with 1714 patients were included. Pre-treatment dissociation was not related to treatment effectiveness in patients with PTSD (Pearson's correlation coefficient 0.04, 95% CI -0.04 to 0.13). Between-study heterogeneity was high but was not explained by moderators such as trauma focus of the psychotherapy or risk of bias score. There was no indication for publication bias.

CONCLUSIONS

We found no evidence that dissociation moderates the effectiveness of psychotherapy for PTSD. The quality of some of the included studies was relatively low, emphasising the need for high-quality clinical trials in patients with PTSD. The results suggest that pre-treatment dissociation does not determine psychotherapy outcome in PTSD.

Dissociative subtype of posttraumatic stress disorder in women in partial and residential levels of psychiatric care

The dissociative subtype of posttraumatic stress disorder (PTSD) is estimated to characterize about 12-30% of those with PTSD. Some research links this subtype with increased severity of PTSD symptoms compared to samples with "classic" PTSD. However, prevalence and severity rates reported in the literature have varied. One possible explanation for these discrepancies could be related to where the populations were sampled. Therefore, we investigated whether these differences are still observed when holding level of care constant. We collected data from 104 women at a partial and residential psychiatric hospital program focused on trauma-related disorders. Participants completed self-report questionnaires assessing trauma exposure, symptoms and provisional diagnosis of PTSD, trauma-related thoughts and beliefs, and feelings of shame. All participants reported a history of childhood and/or adulthood trauma exposure. Eighty-eight (85%) met criteria for PTSD, and of those, seventy-three (83%) met criteria for the dissociative subtype as assessed by the Dissociative Subtype of PTSD Scale. A series of independent t-tests revealed no significant differences between the "classic" and dissociative PTSD groups with respect to lifetime or childhood trauma exposure, posttraumatic cognitions, shame, or overall PTSD severity. Our results suggest that samples with classic PTSD and the dissociative subtype may not differ in some types of symptom severity when holding level of care constant. Importantly, however, we found at partial/residential level of care the majority of patients with PTSD were dissociative. Given the elevated prevalence rate in this sample, these findings support the need to assess dissociative symptoms, particularly in more acute psychiatric settings.

The impact of brief intensive trauma-focused treatment for PTSD on symptoms of borderline personality disorder

Background: It is generally recommended to exercise caution in applying trauma-focused treatment to individuals with posttraumatic stress disorder (PTSD) and comorbid borderline personality disorder (BPD). Objective: To investigate the effects of a brief, intensive, direct trauma-focused treatment programme for individuals with PTSD on BPD symptom severity. Methods: Individuals (n = 72) with severe PTSD (87.5% had one or more comorbidities; 52.8% fulfilled the criteria for the dissociative subtype of PTSD) due to multiple traumas (e.g. 90.3% sexual abuse) participated in an intensive eight-day trauma-focused treatment programme consisting of eye movement desensitization and reprocessing (EMDR) and prolonged exposure (PE) therapy, physical activity, and psychoeducation. Treatment did not include any form of stabilization (e.g. emotion regulation training) prior to trauma-focused therapy. Assessments took place at pre- and post-treatment (Borderline Symptom List, BSL-23; PTSD symptom severity, Clinician Administered PTSD Scale for DSM-5, CAPS-5), and across the eight treatment days (PTSD Checklist, PCL-5). Results: Treatment resulted in significant decreases of BPD symptoms (Cohen's d = 0.70). Of the 35 patients with a positive screen for BPD at pre-treatment, 32.7% lost their positive screen at post-treatment. No adverse events nor dropouts occurred during the study time frame, and none of the patients experienced symptom deterioration in response to treatment. Conclusion: The results suggest that an intensive trauma-focused treatment is a feasible and safe treatment for PTSD patients with clinically elevated symptoms of BPD, and that BPD symptoms decrease along with the PTSD symptoms.

Do emotion regulation difficulties affect outcome of intensive trauma-focused treatment of patients with severe PTSD?

Background: There is ongoing debate as to whether emotion regulation problems should be improved first in order to profit from trauma-focused treatment, or will diminish after successful trauma processing. Objective: To enhance our understanding about the importance of emotion regulation difficulties in relation to treatment outcomes of trauma-focused therapy of adult patients with severe PTSD, whereby we made a distinction between people who reported sexual abuse before the age of 12, those who were 12 years or older at the onset of the abuse, individuals who met the criteria for the dissociative subtype of PTSD, and those who did not. Methods: Sixty-two patients with severe PTSD were treated using an intensive eight-day treatment programme, combining two first-line trauma-focused treatments for PTSD (i.e. prolonged exposure and EMDR therapy) without preceding interventions that targeted emotion regulation difficulties. PTSD symptom scores (CAPS-5) and emotion regulation difficulties (DERS) were assessed at pre-treatment, post-treatment, and six month follow-up. Results: PTSD severity and emotion regulation difficulties significantly decreased following trauma-focused treatment. While PTSD severity scores significantly increased from post-treatment until six month follow-up, emotion regulation difficulties did not. Treatment response and relapse was not predicted by emotion-regulation difficulties. Survivors of childhood sexual abuse before the age of 12 and those who were sexually abused later in life improved equally well with regard to emotion regulation difficulties. Individuals who fulfilled criteria of the dissociative subtype of PTSD showed a similar decrease on emotion regulation difficulties during treatment than those who did not. Conclusion: The results support the notion that the severity of emotion regulation difficulties is not associated with worse trauma-focused treatment outcomes for PTSD nor with relapse after completing treatment. Further, emotion regulation difficulties improved after trauma-focused treatment, even for individuals who had been exposed to early childhood sexual trauma and individuals with dissociative subtype.

The Current Status of EMDR Therapy Involving the Treatment of Complex Posttraumatic Stress Disorder

Complex posttraumatic stress disorder (CPTSD) is a diagnostic entity that will be included in the forthcoming edition of the International Classification of Diseases, 11th Revision (ICD-11). It denotes a severe form of PTSD, comprising not only the symptom clusters of PTSD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV-TR]), but also clusters reflecting difficulties in regulating emotions, disturbances in relational capacities, and adversely affected belief systems about oneself, others, or the world. Evidence is mounting suggesting that first-line trauma-focused treatments, including eye movement desensitization and reprocessing (EMDR) therapy, are effective not only for the treatment of PTSD, but also for the treatment of patients with a history of early childhood interpersonal trauma who are suffering from symptoms characteristic of CPTSD. However, controversy exists as to when EMDR therapy should be offered to people with CPTSD. This article reviews the evidence in support of EMDR therapy as a first-line treatment for CPTSD and addresses the fact that there appears to be little empirical evidence supporting the view that there should be a stabilization phase prior to trauma processing in working with CPTSD.

A protocol for managing dissociative symptoms in refugee populations

This article describes a clinical protocol for supporting those presenting with post-traumatic stress disorder (PTSD) and dissociative symptoms, particularly dissociative flashbacks, based on a cross-culturally applicable model. The protocol is discussed from the perspective of working with a refugee and asylum seeker population, although many of the principles will be applicable to clients from any background presenting with these dissociative symptoms. The protocol addresses the assessment and formulation of a client’s dissociative symptoms. It includes guidance on sharing psycho-education with clients regarding the evolutionary function of dissociation and developing practical strategies to monitor and manage dissociative symptoms. The strengths and limitations of this protocol are also discussed.

Trauma-related altered states of consciousness in post-traumatic stress disorder patients with or without comorbid dissociative disorders

Background: The four-dimensional ('4-D') model has been proposed as a theoretical framework to understand and delineate trauma-related dissociative experiences, categorizing symptoms into trauma-related altered states of consciousness (TRASC) and normal waking consciousness (NWC), which occur along four dimensions: time, thought, body and emotion. Objective: The main aim of the present study was to evaluate the validity of this model in patients with post-traumatic stress disorder (PTSD), with and without comorbid dissociative disorders. Method: The predictions of the 4-D model were tested in 142 patients with PTSD, with (N = 46) and without (N = 96) comorbid dissociative disorders. Results: As predicted by the 4-D model, experiences of TRASC were less frequent and more specifically related to other measures of dissociation, dissociative disorder comorbidity and a history of childhood sexual abuse compared to experiences of NWC. The predicted lower intercorrelation of TRASC was not supported. Conclusion: The 4-D model represents a promising framework for understanding dissociation across trauma-related disorders.

Effectiveness of an intensive treatment programme combining prolonged exposure and eye movement desensitization and reprocessing for severe post-traumatic stress disorder

Background: There is room for improvement regarding the treatment of severe post-traumatic stress disorder (PTSD). Intensifying treatment to increase patient retention is a promising development. Objective: The aim of this study was to determine the effectiveness of an intensive trauma-focused treatment programme over 8 days for individuals suffering from severe PTSD. Method: Treatment was provided for 347 PTSD patients (70% women; mean age = 38.32 years, SD = 11.69) and consisted of daily sessions of prolonged exposure and eye movement desensitization and reprocessing (EMDR) therapy (16 sessions in total), physical activity, and psycho-education. All participants had experienced multiple traumas, including sexual abuse (74.4%), and suffered from multiple comorbidities (e.g. 87.5% had a mood disorder). Suicidal ideation was frequent (73.9%). PTSD symptom severity was assessed by both clinician-rated [Clinician Administered PTSD Scale (CAPS)] and self-report [PTSD Symptom Scale Self Report (PSS-SR) and Impact of Event Scale (IES)] inventories. For a subsample (n = 109), follow-up data at 6 months were available. Results: A significant decline in symptom severity was found (e.g. CAPS intention-to-treat sample Cohen's d = 1.64). At post-treatment, 82.9% showed a clinically meaningful response and 54.9% a loss of diagnosis. Dropout was very low (2.3%). Conclusions: Intensive trauma-focused treatment programmes including prolonged exposure, EMDR therapy, and physical activity can be effective for patients suffering from severe PTSD and are associated with low dropout rates.
