Effectiveness of trauma-focused treatment for patients with psychosis with and without the dissociative subtype of post-traumatic stress disorder

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.

Eye movement desensitisation and reprocessing as add-on treatment to enhanced cognitive behaviour therapy for patients with anorexia nervosa reporting childhood maltreatment: A quasi-experimental multicenter study

OBJECTIVE

This quasi-experimental study aimed to compare the outcome of patients with Anorexia Nervosa (AN) reporting moderate/severe childhood maltreatment (CM) treated exclusively with Enhanced Cognitive Behaviour Therapy (CBT-E) or with CBT-E plus Eye Movement Desensitisation and Reprocessing (EMDR).

METHOD

A total of 75 patients with AN reporting moderate/severe CM were initially assessed regarding body mass index (BMI), general and eating disorder (ED)-specific psychopathology, and dissociative symptoms, and re-evaluated after 40 CBT-E sessions (T1). Then, 18 patients received EMDR, whereas the others were placed on a waiting list and continued CBT-E. T2 assessment was performed after 20-25 sessions of EMDR or CBT-E. A control group of 67 patients without CM was also enroled and treated with CBT-E.

RESULTS

Contrary to patients without CM, neither of the traumatised groups improved in BMI, general and ED psychopathology, or dissociation at T1. However, at T2, both traumatised groups improved in BMI and ED-specific psychopathology, with the CBT + EMDR group demonstrating greater improvements. Moreover, only the CBT + EMDR group improved in general psychopathology and dissociative symptoms. The reduction of ED symptoms in traumatised patients was mediated by the amelioration of dissociation.

DISCUSSION

The addition of EMDR to CBT-E may benefit patients with AN reporting moderate/severe CM.

Trauma and Trauma-Informed Care in Early Intervention in Psychosis: State of Implementation and Provider Views on Challenges

OBJECTIVE

Although trauma is increasingly recognized as a major risk factor for psychosis and for its link to treatment outcomes, the landscape of trauma-related practices in specialized early psychosis services in the United States and other countries remains only poorly characterized. Research documenting the perspectives of frontline providers is also lacking. The primary goals of this study were to document the state of trauma-related policy implementation in early intervention in psychosis (EIP) programs and to gather provider perspectives.

METHODS

This was a mixed-methods project involving an international EIP provider survey, followed by in-depth provider interviews. The survey was disseminated in Australia, Canada, Chile, the United Kingdom, and the United States. In total, 164 providers, representing 110 unique sites, completed the survey. Frequencies were calculated for responses to survey items, and open-ended responses were analyzed with a systematic content analysis.

RESULTS

The survey findings suggested low implementation rates for a variety of assessment and support practices related to trauma and trauma-informed care. Coding of open-ended responses revealed numerous concerns and uncertainties among providers regarding the relationship between trauma and psychosis and the state of the EIP field.

CONCLUSIONS

An expansion of research and service development aimed at better meeting the trauma-related needs of young people with psychosis is essential, with implications for EIP outcomes and service user and staff experiences.

A multiple baseline trial of adapted prolonged exposure psychotherapy for individuals with early phase psychosis, comorbid substance misuse, and a history of adversity: A study protocol

Background

Adversity is prevalent among people with psychotic disorders, especially those within the first 5 years of a psychotic disorder, called early phase psychosis. Although adversity can lead to many negative outcomes (e.g., posttraumatic stress symptoms), very few treatments for adversity-related sequelae have been tested with individuals with psychotic disorders, and even fewer studies have specifically tested interventions for people in early phase psychosis. Furthermore, people who misuse substances are commonly excluded from adversity treatment trials, which is problematic given that individuals with early phase psychosis have high rates of substance misuse. For the first time, this trial will examine the outcomes of an adapted 15-session prolonged exposure protocol (i.e., PE+) to observe whether reductions in adversity-related psychopathology occurs among people with early phase psychosis and comorbid substance misuse.

Methods

This study will use a multiple-baseline design with randomization of participants to treatment start time. Participants will complete baseline appointments prior to therapy, engage in assessments between each of the five therapy modules, and complete a series of follow-up appointments 2 months after the completion of therapy. Primary hypothesized outcomes include clinically significant reductions in (1) negative psychotic symptoms measured using the Positive and Negative Syndrome Scale, (2) adversity-related sequelae measured using the Trauma Symptom Checklist-40, and (3) substance use frequency and overall risk score measured with the Alcohol, Smoking, and Substance Involvement Screening Test. We also anticipate that clinically significant reductions in hopelessness and experiential avoidance, measured with the Beck Hopelessness Scale and Brief Experiential Avoidance Questionnaire, the theorized mechanisms of change of PE+, will also be observed. A secondary outcome is a hypothesized improvement in functioning, measured using the Clinical Global Impression and Social and Occupational Functioning Assessment scales.

Discussion

The results of this treatment trial will contribute to the advancement of treatment research for individuals in early phase psychosis who have current substance misuse and a history of adversity, and the findings may provide evidence supporting the use of hopelessness and experiential avoidance as mechanisms of change for this 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.

Exploring Therapists' Experiences of Applying EMDR Therapy With Clients Experiencing Psychosis

Little is known of the usability of eye movement desensitization and reprocessing (EMDR) as an intervention for those experiencing psychosis. This study aimed to explore therapists' experience of using EMDR with this population. A qualitative design was employed using an inductive approach and a thematic analysis. Twenty therapists, who had used EMDR with this client group, took part in a semi-structured interview to explore their experiences of the intervention. Key themes were generated from the data: (a) familiarity with psychosis and EMDR, (b) acceptability of EMDR, (c) the importance of systemic factors, and (d) keeping key therapy principles in mind. Findings highlighted the importance of supervision to build therapist confidence, the value of the multidisciplinary team, and the need for a shift in beliefs surrounding the usefulness of EMDR to the wider system. Recommendations for individuals and services are provided.

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.

Childhood maltreatment and social functioning in psychotic disorders: a systematic review protocol

Background: Childhood maltreatment (CM) is thought to play a key role in the etiology and course of psychotic disorders (PD). In addition, CM is related to neurobiological and clinical characteristics that can lead to poor social functioning. However, the extent to which CM and social functioning are directly associated in individuals with PD, is unclear. Therefore, we aim to systematically review the literature to provide an estimate on the strength of the association between CM and different domains of social functioning in PD and to summarize potential moderators and mediators of this association.Methods and analysis: To identify relevant studies, we will systematically search the following databases: Pubmed (Medline), PsycInfo, Embase, Web of Science (Core Collection), and Pilots (trauma), manually search reference lists and contact experts in the field. Studies will be included if they investigate and report on the association between CM (exposure) and social functioning (outcome) in adults with PD. Two independent reviewers will screen titles, abstracts and full texts according to eligibility criteria, perform data extraction and assess study quality according to a modified version of the Newcastle-Ottawa Scale.Analysis: Effect estimates will be pooled in a meta-analysis. Heterogeneity and publication bias will be assessed and the effects of potential moderators (genetic factors, type of diagnosis, duration of illness, type of CM and age at the time of CM exposure) will be analyzed using meta-regressions. Candidate moderators and mediators (neurocognition, cognitive schemas, comorbidities, stress sensitivity, attachment) will be also examined qualitatively.Ethics and dissemination: Because this review will make use of already published data, ethical approval will not be sought. This work has the potential to inform upcoming investigations on the association between the exposure to CM in PD and social functioning. PROSPERO registration number CRD42020175244.

Dissociative Symptoms In Posttraumatic Stress Disorder: A Systematic Review

Objectives: Research on dissociative symptomatology in the context of Posttraumatic Stress Disorder (PTSD) has been gaining traction, with dissociation being studied as a set of complex symptoms following trauma exposure and as a specific subtype of PTSD. The aims of this review are to summarize the literature as it stands, examine the efficacy of existing interventions in treating dissociative symptomatology within the context of PTSD, and offer potential suggestions for future research. Methods: A systematic approach was taken to locate empirical studies on PTSD that included dissociation as an outcome in the PubMed, Scopus, and PsycINFO databases. Recent experimental designs with adult subjects (18+ years) in the English language were included, yielding 103 potentially eligible studies. Thirty-three full-text articles were screened with 17 articles meeting criteria for inclusion in the systematic review. Results: Designs, populations, treatments, and inventories were extremely diverse. Most therapies did not target dissociation specifically, although the results of this review suggest that PTSD patients who experience dissociative symptoms could benefit from trauma-focused treatments, which often significantly reduced dissociative and trauma-related symptoms. Conclusion: Future work should consider the evaluation of dissociation as a unique outcome to gain understanding about the nature of traumatic stress and to develop treatment options for its many presentations. The current literature displays limited generalizability to the treatment of individuals with high dissociation, which is a line of inquiry that should be explored. More RCTs are needed.

Psychosocial interventions for conversion and dissociative disorders in adults

BACKGROUND

Conversion and dissociative disorders are conditions where people experience unusual neurological symptoms or changes in awareness or identity. However, symptoms and clinical signs cannot be explained by a neurological disease or other medical condition. Instead, a psychological stressor or trauma is often present. The symptoms are real and can cause significant distress or problems with functioning in everyday life for the people experiencing them.

OBJECTIVES

To assess the beneficial and harmful effects of psychosocial interventions of conversion and dissociative disorders in adults.

SEARCH METHODS

We conducted database searches between 16 July and 16 August 2019. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and eight other databases, together with reference checking, citation searching and contact with study authors to identify additional studies.  SELECTION CRITERIA: We included all randomised controlled trials that compared psychosocial interventions for conversion and dissociative disorders with standard care, wait list or other interventions (pharmaceutical, somatic or psychosocial).  DATA COLLECTION AND ANALYSIS: We selected, quality assessed and extracted data from the identified studies. Two review authors independently performed all tasks. We used standard Cochrane methodology. For continuous data, we calculated mean differences (MD) and standardised mean differences (SMD) with 95% confidence interval (CI). For dichotomous outcomes, we calculated risk ratio (RR) with 95% CI. We assessed and downgraded the evidence according to the GRADE system for risk of bias, imprecision, indirectness, inconsistency and publication bias.

MAIN RESULTS

We included 17 studies (16 with parallel-group designs and one with a cross-over design), with 894 participants aged 18 to 80 years (female:male ratio 3:1).  The data were separated into 12 comparisons based on the different interventions and comparators. Studies were pooled into the same comparison when identical interventions and comparisons were evaluated. The certainty of the evidence was downgraded as a consequence of potential risk of bias, as many of the studies had unclear or inadequate allocation concealment. Further downgrading was performed due to imprecision, few participants and inconsistency. There were 12 comparisons for the primary outcome of reduction in physical signs. Inpatient paradoxical intention therapy compared with outpatient diazepam: inpatient paradoxical intention therapy did not reduce conversive symptoms compared with outpatient diazepam at the end of treatment (RR 1.44, 95% CI 0.91 to 2.28; 1 study, 30 participants; P = 0.12; very low-quality evidence). Inpatient treatment programme plus hypnosis compared with inpatient treatment programme: inpatient treatment programme plus hypnosis did not reduce severity of impairment compared with inpatient treatment programme at the end of treatment (MD -0.49 (negative value better), 95% CI -1.28 to 0.30; 1 study, 45 participants; P = 0.23; very low-quality evidence). Outpatient hypnosis compared with wait list: outpatient hypnosis might reduce severity of impairment compared with wait list at the end of treatment (MD 2.10 (higher value better), 95% CI 1.34 to 2.86; 1 study, 49 participants; P < 0.00001; low-quality evidence). Behavioural therapy plus routine clinical care compared with routine clinical care: behavioural therapy plus routine clinical care might reduce the number of weekly seizures compared with routine clinical care alone at the end of treatment (MD -21.40 (negative value better), 95% CI -27.88 to -14.92; 1 study, 18 participants; P < 0.00001; very low-quality evidence). Cognitive behavioural therapy (CBT) compared with standard medical care: CBT did not reduce monthly seizure frequency compared to standard medical care at end of treatment (RR 1.56, 95% CI 0.39 to 6.19; 1 study, 16 participants; P = 0.53; very low-quality evidence). CBT did not reduce physical signs compared to standard medical care at the end of treatment (MD -4.75 (negative value better), 95% CI -18.73 to 9.23; 1 study, 61 participants; P = 0.51; low-quality evidence). CBT did not reduce seizure freedom compared to standard medical care at end of treatment (RR 2.33, 95% CI 0.30 to 17.88; 1 trial, 16 participants; P = 0.41; very low-quality evidence). Psychoeducational follow-up programmes compared with treatment as usual (TAU): no study measured reduction in physical signs at end of treatment. Specialised CBT-based physiotherapy inpatient programme compared with wait list: no study measured reduction in physical signs at end of treatment. Specialised CBT-based physiotherapy outpatient intervention compared with TAU: no study measured reduction in physical signs at end of treatment. Brief psychotherapeutic intervention (psychodynamic interpersonal treatment approach) compared with standard care: brief psychotherapeutic interventions did not reduce conversion symptoms compared to standard care at end of treatment (RR 0.12, 95% CI 0.01 to 2.00; 1 study, 19 participants; P = 0.14; very low-quality evidence). CBT plus adjunctive physical activity (APA) compared with CBT alone: CBT plus APA did not reduce overall physical impacts compared to CBT alone at end of treatment (MD 5.60 (negative value better), 95% CI -15.48 to 26.68; 1 study, 21 participants; P = 0.60; very low-quality evidence). Hypnosis compared to diazepam: hypnosis did not reduce symptoms compared to diazepam at end of treatment (RR 0.69, 95% CI 0.39 to 1.24; 1 study, 40 participants; P = 0.22; very low-quality evidence). Outpatient motivational interviewing (MI) and mindfulness-based psychotherapy compared with psychotherapy alone: psychotherapy preceded by MI might decrease seizure frequency compared with psychotherapy alone at end of treatment (MD 41.40 (negative value better), 95% CI 4.92 to 77.88; 1 study, 54 participants; P = 0.03; very low-quality evidence). The effect on the secondary outcomes was reported in 16/17  studies. None of the studies reported results on adverse effects. In the studies reporting on level of functioning and quality of life at end of treatment the effects ranged from small to no effect.

AUTHORS' CONCLUSIONS

The results of the meta-analysis and reporting of single studies suggest there is lack of evidence regarding the effects of any psychosocial intervention on conversion and dissociative disorders in adults. It is not possible to draw any conclusions about potential benefits or harms from the included studies.

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.

A Multicenter Phase II RCT to Compare the Effectiveness of EMDR Versus TAU in Patients With a First-Episode Psychosis and Psychological Trauma: A Protocol Design

Background

Patients with a first episode psychosis (FEP) who are admitted for the first time to a psychiatric hospital frequently have experienced prior psychological trauma. Additionally, 40-80% develop posttraumatic stress symptoms, which are summarized as a post-psychotic post-traumatic syndrome (PPS). Eye Movement Desensitization and reprocessing (EMDR) therapy could be an effective psychotherapy to treat a PPS and prior psychological traumas in this population.

Objectives

To assess if EMDR therapy leads to: 1) a reduction of relapses after intervention, 2) an improvement of trauma-related, psychotic and affective symptoms, 3) an improvement of overall functioning, and 4) an improvement in quality of life.

Methods

This is a multicenter phase II rater-blinded randomized controlled trial in which 80 FEP patients with a history of psychological trauma will be randomly assigned to EMDR (n = 40) or to TAU (n = 40). Traumatic events will be measured by the Global Assessment of Posttraumatic Stress Questionnaire, the Cumulative Trauma Screening, the Impact of Event Scale-Revised, the Dissociative Experiences Scale, the Childhood Trauma Scale, the Holmes-Rahe Life Stress Inventory, and the Dissociative Experiences Questionnaire. Clinical symptomatology will be evaluated using the Suicide and Drug Consumption module of the International Neuropsychiatric Interview, Structured Clinical Interview for Positive and Negative Syndrome Scale, Young's Scale for Mania Evaluation, and Beck Depression II Questionnaire. Functionality will be assessed with the Global Assessment of Functioning and the Quality of Life with the Standardized Instrument developed by the EuroQol Group. The cognitive insight and adherence to the treatment will be assessed with the Beck Cognitive Insight Scale and the Drug Attitude Inventory. All variables will be measured at baseline, post-treatment and at 12-month follow-up.

Conclusion

This study will provide evidence of whether EMDR therapy is effective in reducing trauma and clinical symptoms, reducing relapses and in improving functionality and quality of life in patients with FEP and a history of trauma.

Psychosis: An Emerging Field for EMDR Research and Therapy

It has only been in this last decade that trauma-focused treatments (TFT) have been studied in patients with psychotic disorders. Before, the paradigm stated that TFT was contraindicated in these patients because clinicians and researchers assumed the risk of exacerbation of symptoms was too high. The purpose of this article is to examine the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy in the treatment of psychosis. To this end, we will present a brief narrative review of the current state of research in this particular field. The results suggest that, contrary to the “no-TFT-in-psychosis” paradigm, TFTs such as EMDR therapy can successfully be used to reduce trauma-related symptoms in patients with psychosis. Moreover, there are now provisional indications that psychotic symptoms such as delusions and hallucinations can be targeted directly and indirectly using EMDR therapy.

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.

Which patients initiate cognitive processing therapy and prolonged exposure in department of veterans affairs PTSD clinics?

The United States Department of Veterans Affairs (VA) provides Cognitive Processing Therapy (CPT) and Prolonged Exposure therapy (PE) for PTSD at all of its facilities, but little is known about systematic differences between patients who do and do not initiate these treatments. VA administrative data were analyzed for 6,251 veterans receiving psychotherapy over one year in posttraumatic stress disorder (PTSD) specialty clinics at nine VA medical centers. CPT and PE were initiated by 2,173 (35%) patients. Veterans' probability of initiating either CPT or PE (considered together) was 29% lower (adjusted odds ratio = .61) if they had a psychiatric hospitalization within the same year, and 15% lower (AOR = .78) if they had service-connected disability for PTSD. Veterans' probability of starting CPT or PE was 19% lower (AOR = .74) if they were Hispanic or Latino, 10% lower (AOR = .84), if they were male rather than female, and 9% lower (AOR = .87) if they were divorced, separated or widowed rather than currently married. Probability of receiving CPT or PE was also lower if verans had more co-occurring psychiatric diagnoses (AOR per diagnosis = .88), were older (AOR per every five years = .95), or lived further away from the VA clinic (AOR per every ten miles = .98). Nonetheless, most patients initiating CPT or PE had two or more comorbidities and were service-connected for PTSD. Observed gender, age and ethnic differences in initiation of CPT and PE appear unrelated to clinical suitability and warrant further study.

Cognitive behavioural therapy for psychosis targeting trauma, voices and dissociation: a case report

Trauma and dissociation may be important factors contributing to the experiences of distressing voice hearing. However, there is scant mention of how to target and treat such processes when working with people with psychosis. This case study reports on an initial attempt to work with dissociation and trauma memories in a person with voices. A single case approach was used, with standardized measures used before, during and after 24 sessions of cognitive therapy, and at 6-month follow-up. In addition, session-by-session measures tracked frequency and distress associated with voices and dissociation. The participant reported significant improvements in terms of reduced frequency and distress of dissociation, and voice hearing, as well as improvement in low mood at the end of treatment. At follow-up there were enduring benefits in terms of dissociation and trauma-related experiences, as well as broad recovery but not of change in voices. This case illustrated the potential benefit of targeting dissociation and exposure to trauma memories in producing general symptom improvement and specific reductions in dissociation and voice hearing at end of treatment.

Treating the "E" in "G × E": Trauma-Informed Approaches and Psychological Therapy Interventions in Psychosis

Despite advances in genetic research, causal variants affecting risk for schizophrenia remain poorly characterized, and the top 108 loci identified through genome-wide association studies (GWAS) explain only 3.4% of variance in risk profiles. Such work is defining the highly complex nature of this condition, with omnigenic models of schizophrenia suggesting that gene regulatory networks are sufficiently interconnected such that altered expression of any "peripheral" gene in a relevant cell type has the capacity to indirectly modulate the expression of "core" schizophrenia-associated genes. This wealth of associated genes with small effect sizes makes identifying new druggable targets difficult, and current pharmacological treatments for schizophrenia can involve serious side effects. However, the fact that the majority of schizophrenia genome-wide associated variants fall within non-coding DNA is suggestive of their potential to modulate gene regulation. This would be consistent with risks that can be mediated in a "gene × environment" (G × E) manner. Stress and trauma can alter the regulation of key brain-related pathways over the lifetime of an individual, including modulation of brain development, and neurochemistry in the adult. Recent studies demonstrate a significant overlap between psychotic symptoms and trauma, ranging from prior trauma contributing to psychosis, as well as trauma in response to the experience of psychosis itself or in response to treatment. Given the known effects of trauma on both CNS gene expression and severity of psychosis symptoms, it may be that pharmacological treatment alone risks leaving individuals with a highly stressful and unresolved environmental component that continues to act in a "G × E" manner, with the likelihood that this would negatively impact recovery and relapse risk. This review aims to cover the recent advances elucidating the complex genetic architecture of schizophrenia, as well as the long-term effects of early life trauma on brain function and future mental health risk. Further, the evidence demonstrating the role of ongoing responses to trauma or heightened stress sensitivity, and their impact on the course of illness and recovery, is presented. Finally, the need for trauma-informed approaches and psychological therapy-based interventions is discussed, and a brief overview of the evidence to determine their utility is presented.

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

Background: There is a widely-held belief in the trauma field that the presence of dissociative symptoms is associated with poor treatment response. However, previous research on the effect of dissociation in treatment outcomes pertained to specific patients and trauma populations. Objective: To test the hypothesis that the presence of the dissociative subtype of PTSD (DS) would have a detrimental effect on the outcome of an intensive trauma-focused treatment programme. Methods: PTSD symptom scores (Clinician Administered PTSD Scale [CAPS] and PTSD Symptom Scale Self-Report [PSS-SR]) were analysed using the data of 168 consecutive patients (70.6% female) who had been exposed to a wide variety of multiple traumas, including childhood sexual abuse, and of whom 98.2% were diagnosed with severe PTSD (CAPS > 65). Most of them suffered from multiple comorbidities and 38 (22.6%) met the criteria for DS. They took part in an intensive trauma-focused treatment programme for PTSD. Pre- and post-treatment differences were compared between patients with and without DS. Results: Large effect sizes were achieved for PTSD symptom reduction on CAPS and the PSS-SR, both for patients with DS and those without. Although patients with DS showed a significantly greater PTSD symptom severity at the beginning, and throughout, treatment, both groups showed equal reductions in PTSD symptoms. Of those who met the criteria for DS, 26 (68.4%) no longer fulfilled the criteria for this classification after treatment. Conclusion: The results provide no support for the notion that the presence of DS negatively impacts trauma-focused treatment outcomes. Accordingly, PTSD patients with DS should not be denied effective trauma-focused treatments.

EMDR beyond PTSD: A Systematic Literature Review

Background: Eye Movement Desensitization and Reprocessing (EMDR) is a psychotherapeutic approach that has demonstrated efficacy in the treatment of Post-traumatic Stress Disorder (PTSD) through several randomized controlled trials (RCT). Solid evidence shows that traumatic events can contribute to the onset of severe mental disorders and can worsen their prognosis. The aim of this systematic review is to summarize the most important findings from RCT conducted in the treatment of comorbid traumatic events in psychosis, bipolar disorder, unipolar depression, anxiety disorders, substance use disorders, and chronic back pain.

Methods: Using PubMed, ScienceDirect, and Scopus, we conducted a systematic literature search of RCT studies published up to December 2016 that used EMDR therapy in the mentioned psychiatric conditions.

Results: RCT are still scarce in these comorbid conditions but the available evidence suggests that EMDR therapy improves trauma-associated symptoms and has a minor effect on the primary disorders by reaching partial symptomatic improvement.

Conclusions: EMDR therapy could be a useful psychotherapy to treat trauma-associated symptoms in patients with comorbid psychiatric disorders. Preliminary evidence also suggests that EMDR therapy might be useful to improve psychotic or affective symptoms and could be an add-on treatment in chronic pain conditions.

Intensive EMDR to Treat Patients With Complex Posttraumatic Stress Disorder: A Case Series

There is mounting evidence suggesting that by increasing the frequency of treatment sessions, posttraumatic stress disorder (PTSD) treatment outcomes significantly improve. As part of an ongoing research project, this study examined the safety and effectiveness of intensive eye movement desensitization and reprocessing (EMDR) therapy in a group of seven (four female) patients suffering from complex PTSD and multiple comorbidities resulting from childhood sexual abuse, physical abuse, and/or work and combat-related trauma. Treatment was not preceded by a preparation phase and consisted of 2 × 4 consecutive days of EMDR therapy administered in morning and afternoon sessions of 90 minutes each, interspersed with intensive physical activity and psychoeducation. Outcome measures were the Clinician-Administered PTSD Scale (CAPS) and the PTSD Symptom Scale Self-report questionnaire (PSS-SR). During treatment, neither personal adverse events nor dropout occurred. CAPS scores decreased significantly from pre- to posttreatment, and four of the seven patients lost their PTSD diagnosis as established with the CAPS. The results were maintained at 3-month follow-up. Effect sizes (Cohen’s d) on the CAPS and PSS-SR were large: 3.2, 1.7 (prepost) and 2.3, 2.1 (prefollow-up), respectively. The results of this case series suggest that an intensive program using EMDR therapy is a potentially safe and effective treatment alternative for complex PTSD. The application of massed, consecutive days of treatments using EMDR therapy for patients suffering from PTSD, particularly those with multiple comorbidities, merits more clinical and research attention.
