Do all psychological treatments really work the same in posttraumatic stress disorder?

Self-compassion mediates treatment effects in MDMA-assisted therapy for posttraumatic stress disorder

Background: Posttraumatic stress disorder (PTSD) is a severe condition often complicated by co-occurring disorders, such as major depression, alcohol use disorder, and substance use disorders. A well-powered phase 3 randomized, placebo-controlled trial has shown that MDMA-assisted therapy (MDMA-AT) may be an effective treatment for severe PTSD. However, the psychological mechanisms driving the therapeutic effects of MDMA-AT remain unclear. One potential mechanism is self-compassion, which is commonly conceptualized as a balance between compassionate self-responding (CS) - encompassing self-kindness, common humanity, and mindfulness - and uncompassionate self-responding (UCS) - encompassing self-judgment, isolation, and over-identification.Objective: This secondary analysis aimed to explore whether MDMA-AT enhances aspects of self-compassion and if changes in self-compassion mediate the therapy's effectiveness in reducing PTSD severity, depressive, and alcohol and substance use symptoms.Method: Eighty-two adults diagnosed with severe PTSD participated in a double-blind trial comparing three sessions of either MDMA-AT or placebo combined with therapy. Measures of PTSD severity, depressive symptoms, alcohol and substance use, and self-compassion were collected at baseline and 18 weeks later.Results: MDMA-AT led to statistically significant improvements in both UCS and CS. Significant improvements were also observed across all six subscales of the Self-Compassion Scale, including self-kindness, self-judgment, common humanity, isolation, mindfulness, and over-identification, most with large effect sizes. Changes in UCS and CS significantly and fully mediated the effects of MDMA-AT compared to placebo plus therapy in reducing PTSD severity and depressive symptoms. Findings were not significant for alcohol and substance use outcomes.Conclusions: These findings suggest that self-compassion may play a critical role in the therapeutic effects of MDMA-AT. Further research is needed to investigate the role of self-compassion in MDMA-AT to refine and develop more targeted, effective interventions for individuals with PTSD and co-occurring depression.

A Meta-Analysis of Interpersonal and Psychodynamic Psychotherapies for Posttraumatic Stress Disorder

OBJECTIVE

Established trauma-focused cognitive-behavioral therapies for posttraumatic stress disorder (PTSD) have remission rates of approximately 30%-40%. Alternatively, interpersonal psychotherapy (IPT) and psychodynamic psychotherapy (PDT) focus on disrupted attachment, mentalization, and social connection in PTSD and may help some patients. The authors conducted a meta-analysis on these interpersonal and affect-oriented approaches to treating PTSD.

METHODS

Building on a prior meta-analysis, the authors searched for randomized controlled trials (RCTs) comparing IPT or PDT with other established PTSD treatments or control conditions for adults diagnosed as having PTSD. Random-effects meta-analyses were conducted to assess outcome effect sizes and dropout rates. RCTs were rated via the Randomized Controlled Trial Psychotherapy Quality Rating Scale.

RESULTS

Ten RCTs (eight of IPT) comparing IPT or PDT with control (k=7) or active treatment (k=4) conditions were identified, nine of which were of adequate quality. IPT (k=5) and PDT (k=2), when analyzed together, were superior to control conditions overall (g=-1.14, p=0.011 [as was IPT alone: g=-0.88, p=0.034]) and to waitlist (g=-1.49) and treatment-as-usual (g=-0.70) groups. Effect sizes, however, may have been inflated by outliers or publication bias. IPT (k=3) and PDT (k=1), when analyzed together, were equally efficacious compared with other active PTSD treatments (primarily exposure-based psychotherapies), as was IPT alone, and had lower dropout rates (relative risk=0.63, p=0.049 for IPT and PDT analyzed together; relative risk=0.61, p=0.098 for IPT alone).

CONCLUSIONS

Affect-focused therapies hold promise in the treatment of PTSD. IPT has demonstrated efficacy in multiple trials, whereas the evidence base for PDT is sparse.

Assessing Dysfunctional Expectations in Posttraumatic Stress Disorder: Development and Validation of the Posttraumatic Expectations Scale (PTES)

Dysfunctional expectations are a particularly important subset of cognitions that influence the development and maintenance of various mental disorders. This study aimed to develop and validate a scale to assess dysfunctional expectations in posttraumatic stress disorder (PTSD), the "Posttraumatic Expectations Scale" (PTES). In a cross-sectional study, 70 PTSD patients completed the PTES, the Posttraumatic Cognitions Inventory (PTCI), as well as measures of the severity of symptoms of PTSD and depression. The results show that the PTES has excellent internal consistency and correlates significantly with the PTCI and PTSD symptom severity. A regression analysis revealed that the PTES explained variance of PTSD symptom severity above the PTCI, supporting the incremental validity of the PTES. While the original version of the PTES comprises 81 items, short scales were constructed using the BISCUIT (best items scales that are cross-validated, unit-weighted, informative and transparent) method. The current findings provide preliminary psychometric evidence suggesting that the PTES is an internally consistent and valid novel self-report measure in patients with PTSD. However, conclusions about the psychometric properties of the PTES are limited because of the absence of criterion-related validity, factor structure evidence, variability over time/response to intervention, and test-retest reliability. Future research should use the PTES in large-scale longitudinal studies to address these aspects to further validate the scale.

A systematic review and meta-analysis of individual and couple therapies for posttraumatic stress disorder: Clinical and intimate relationship outcomes

The association between symptoms of posttraumatic stress disorder (PTSD) in adults and difficulties in intimate relationships is well documented. Growing literature suggests that interpersonally-oriented therapies, such as couple and family interventions, may lead to improvements in both PTSD symptoms and intimate relationship functioning. However, it is unknown how individual PTSD treatments compare to couple/family interventions in relational outcomes. The present study was a systematic review and meta-analysis of individual and couple/family treatments to examine changes in PTSD symptoms and intimate relationship functioning. Twelve couple treatment studies with 13 unique samples and 7 individual treatment studies with 9 unique samples met inclusion criteria. No family-based treatments were identified. Meta-analytic findings indicated moderate to large reductions in PTSD symptoms for both couple and individual studies. Small but significant improvements in intimate relationship functioning across individual and couple studies were observed. Moderation analysis suggested that across both individual and couple treatment formats, trauma-focused treatments had larger effects on PTSD symptoms. Trauma-focused treatments had larger effects on intimate relationship functioning for individual studies. Military status did not moderate outcomes. This study supports the utility of both individual and couple treatment formats for treating PTSD and provides preliminary support for these modalities for also enhancing intimate relationship functioning.

The relationship between youth involvement, alliance and outcome in trauma-focused cognitive behavioral therapy

OBJECTIVE

Research suggests that combining the trauma-specific elements with a strong alliance helps optimize treatment outcomes in Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth. Building on this, we investigate whether more positive and less negative involvement behaviors during trauma narration are associated with a stronger alliance and predict fewer posttraumatic stress symptoms (PTSS).

METHOD

Participants were 65 youth (M age = 15.5, SD = 2.2; 77% girls) receiving TF-CBT. Both youth self-report (Child PTSD Symptom Scale and Therapeutic Alliance Scale for Children) and observer ratings (Client Involvement Rating Scale) were used, and relationships were investigated with correlations and regression analyses.

RESULTS

The positive involvement behaviors demonstration of treatment understanding and self-disclosure predicted fewer PTSS but were not associated with the alliance - while initiation of discussions and showing enthusiasm predicted more PTSS but were associated with a stronger alliance. The negative involvement behaviors passivity and avoidance did not predict PTSS but were negatively associated with the alliance.

CONCLUSION

The relationships between traumatized youths' positive and negative involvement behaviors, alliance and PTSS outcomes appear mixed. The combination of a clear understanding of why processing the trauma can be helpful, more trauma-related self-disclosure and a stronger alliance seem favorable for alleviating PTSS.Trial registration: ClinicalTrials.gov identifier: NCT00635752..

Translational relevance of forward genetic screens in animal models for the study of psychiatric disease

Psychiatric disorders represent a significant burden in our societies. Despite the convincing evidence pointing at gene and gene-environment interaction contributions, the role of genetics in the etiology of psychiatric disease is still poorly understood. Forward genetic screens in animal models have helped elucidate causal links. Here we discuss the application of mutagenesis-based forward genetic approaches in common animal model species: two invertebrates, nematodes (Caenorhabditis elegans) and fruit flies (Drosophila sp.); and two vertebrates, zebrafish (Danio rerio) and mice (Mus musculus), in relation to psychiatric disease. We also discuss the use of large scale genomic studies in human populations. Despite the advances using data from human populations, animal models coupled with next-generation sequencing strategies are still needed. Although with its own limitations, zebrafish possess characteristics that make them especially well-suited to forward genetic studies exploring the etiology of psychiatric disorders.

Putting the "mental" back in "mental disorders": a perspective from research on fear and anxiety

Mental health problems often involve clusters of symptoms that include subjective (conscious) experiences as well as behavioral and/or physiological responses. Because the bodily responses are readily measured objectively, these have come to be emphasized when developing treatments and assessing their effectiveness. On the other hand, the subjective experience of the patient reported during a clinical interview is often viewed as a weak correlate of psychopathology. To the extent that subjective symptoms are related to the underlying problem, it is often assumed that they will be taken care of if the more objective behavioral and physiological symptoms are properly treated. Decades of research on anxiety disorders, however, show that behavioral and physiological symptoms do not correlate as strongly with subjective experiences as is typically assumed. Further, the treatments developed using more objective symptoms as a marker of psychopathology have mostly been disappointing in effectiveness. Given that "mental" disorders are named for, and defined by, their subjective mental qualities, it is perhaps not surprising, in retrospect, that treatments that have sidelined mental qualities have not been especially effective. These negative attitudes about subjective experience took root in psychiatry and allied fields decades ago when there were few avenues for scientifically studying subjective experience. Today, however, cognitive neuroscience research on consciousness is thriving, and offers a viable and novel scientific approach that could help achieve a deeper understanding of mental disorders and their treatment.

The subjective effect of antipsychotic medication on trauma-related thoughts, emotions, and physical symptoms: A qualitative study with people who have experienced childhood trauma and psychosis

OBJECTIVES

Among people with psychosis, those with a history of childhood trauma are likely to experience trauma-related symptoms, such as trauma memory intrusions. Irrespective of whether these individuals continue to remember and re-experience trauma, their treatment very often includes alleviating psychotic symptoms through the use of antipsychotic medication. Antipsychotics, while primarily used to treat psychotic symptoms, can influence non-psychotic symptoms and alter how people think and feel. We thus aimed to explore how people with childhood trauma and psychosis experience the effects that antipsychotics have on their (1) thoughts, images, and memories, (2) emotions, and (3) physical responses, related to their childhood trauma.

DESIGN

A qualitative phenomenological research design using semi-structured interviews was implemented.

METHODS

Data were analysed using interpretative phenomenological analysis.

RESULTS

Nineteen participants were interviewed. Two super-ordinate themes were conceptualized. Many participants spoke about the impact of antipsychotics on trauma-related experiences (Theme 1). Some indicated that antipsychotics alleviated the intensity and frequency of trauma-related thoughts, emotions, and physical symptoms. A few others reported that their trauma-related flashbacks, thoughts, and physical symptoms intensified while taking antipsychotics. Participants spoke about the role of antipsychotics in confronting and processing trauma (Theme 2). A few participants reported that by suppressing trauma-related thoughts and emotions antipsychotics prevented them from confronting their trauma.

CONCLUSIONS

The effects of antipsychotics can be subjectively experienced as beneficial or detrimental depending on how they influence trauma-related thoughts, emotions, and physical responses. Intervention studies are needed to determine how people with childhood trauma and psychosis respond to antipsychotic drugs.

PRACTITIONER POINTS

Antipsychotics may alter the way in which people with childhood trauma and psychosis remember and re-experience trauma. These alterations can be beneficial or detrimental, and thus play a role in whether people consider their medication helpful. By suppressing trauma-related thoughts and emotions, antipsychotics can prevent people from confronting their trauma. This may be considered beneficial to some, but other people may need or want to confront their trauma to heal. The effectiveness of trauma-focused psychological therapies may be influenced by the emotional, cognitive, and physiological effects of antipsychotic medications. The ability of antipsychotics to suppress people's trauma memories may contribute to post-traumatic avoidance. People with post-traumatic stress symptoms and psychosis should be provided with psycho-education about post-traumatic avoidance and its role in the maintenance of post-traumatic stress disorder.

Long-term outcomes of psychological treatment for posttraumatic stress disorder: a systematic review and meta-analysis

Several types of psychological treatment for posttraumatic stress disorder (PTSD) are considered well established and effective, but evidence of their long-term efficacy is limited. This systematic review and meta-analysis aimed to investigate the long-term outcomes across psychological treatments for PTSD. MEDLINE, Cochrane Library, PTSDpubs, PsycINFO, PSYNDEX, and related articles were searched for randomized controlled trials with at least 12 months of follow-up. Twenty-two studies (N = 2638) met inclusion criteria, and 43 comparisons of cognitive behavioral therapy (CBT) were available at follow-up. Active treatments for PTSD yielded large effect sizes from pretest to follow-up and a small controlled effect size compared with non-directive control groups at follow-up. Trauma-focused treatment (TFT) and non-TFT showed large improvements from pretest to follow-up, and effect sizes did not significantly differ from each other. Active treatments for comorbid depressive symptoms revealed small to medium effect sizes at follow-up, and improved PTSD and depressive symptoms remained stable from treatment end to follow-up. Military personnel, low proportion of female patients, and self-rated PTSD measures were associated with decreased effect sizes for PTSD at follow-up. The findings suggest that CBT for PTSD is efficacious in the long term. Future studies are needed to determine the lasting efficacy of other psychological treatments and to confirm benefits beyond 12-month follow-up.

Optimizing treatment for comorbid borderline personality disorder and posttraumatic stress disorder: A systematic review of psychotherapeutic approaches and treatment efficacy

Comorbid borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) is a severe and complicated clinical presentation characterized by especially high rates of suicide, healthcare utilization, and psychosocial impairment. Although guidelines exist for treating each of these disorders alone, there remains limited guidance on the optimal treatment in cases where BPD and PTSD co-occur. Therefore, this systematic review synthesizes the existing research on the treatment of BPD-PTSD with the aim of optimizing treatment for this population. First, the prevalence and clinical severity of comorbid BPD-PTSD is reviewed. Next, we describe the results of our systematic review, which identified 21 articles that examined treatment outcomes in the context of BPD-PTSD or subclinical BPD-PTSD. Based on our results, we describe existing psychotherapeutic approaches, including BPD-specific treatments, trauma-focused and non-trauma-focused treatments for PTSD, and stage-based treatments for BPD-PTSD. We also summarize BPD-PTSD treatment outcomes, including whether each disorder interferes with treatment and recovery of the other. Results related to treatment safety and concerns regarding conducting trauma-focused treatment for BPD-PTSD are addressed. We end by highlighting important gaps in the literature and provide recommendations for further research.

Psychedelics and Psychotherapy

Psychedelics have shown great promise in modern clinical trials for treating various psychiatric conditions. As a transdiagnostic treatment that exerts its effects through subjective experiences that leave enduring effects, it is akin to psychotherapy. To date, there has been insufficient discussion of how psychedelic therapy is similar to and different from conventional psychotherapy. In this article, we review the shared features of effective conventional psychotherapies and situate therapeutic psychedelic effects within those. We then discuss how psychedelic drug effects might amplify conventional psychotherapeutic processes-particularly via effects on meaning and relationship-as well as features that make psychedelic treatment unique. Taking into account shared features of conventional psychotherapies and unique psychedelic drug effects, we create a framework for understanding why psychedelics are likely to be effective with very diverse types of psychotherapies. We also review the formal psychotherapies that have been adjunctively included in modern psychedelic trials and extend the understanding of psychedelics as psychotherapy towards implications for clinical ethics and trial design. We aim to provide some common conceptual vocabulary that can be used to frame therapeutic psychedelic effects beyond the confines of any one specific modality.

Randomised controlled trial of integrated trauma-focused psychotherapy for traumatic stress and substance use among adolescents: trial protocol

INTRODUCTION

Post-traumatic stress disorder (PTSD) and substance use disorder frequently co-occur and tend to have their onset during adolescence. Although research has highlighted the importance of treating these disorders in an integrated fashion, there is a dearth of empirically validated integrated treatment options for adolescents with this comorbidity. This paper describes the study protocol for a randomised controlled trial (RCT) examining the efficacy of an integrated trauma-focused cognitive-behavioural treatment for traumatic stress and substance use among adolescents (Concurrent Treatment of PTSD and Substance Use Using Prolonged Exposure - Adolescent (COPE-A)), relative to a supportive counselling control condition (Person-Centred Therapy (PCT)).

METHODS AND ANALYSIS

A two-arm, parallel, single-blind RCT with blinded follow-up at 4 and 12 months poststudy entry will be conducted in Sydney, Australia. Participants (n~100 adolescents aged 12-18 years) and their caregivers (caregiver participation is optional) will be allocated to undergo either COPE-A or PCT (allocation ratio 1:1) using minimisation. Both therapies will be delivered individually by project psychologists over a maximum of 16 sessions of 60-90 min duration and will include provision of up to four 30 min optional caregiver sessions. The primary outcome will be between-group differences in change in the severity of PTSD symptoms from baseline to 4-month follow-up, as measured by the Clinician-Administered PTSD Scale for Children and Adolescents for DSM-5.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the human research ethics committees of the Sydney Children's Hospital Network (HREC/17/SCHN/306) and the University of Sydney (HREC 2018/863). Findings will be published in peer-reviewed journals and presented at scientific conferences.

The role of trauma experiences, personality traits, and genotype in maintaining posttraumatic stress disorder symptoms among child survivors of the Wenchuan earthquake

BACKGROUND

Posttraumatic stress disorder (PTSD) is the most prevalent type of psychiatric disorder among children after an earthquake. This study investigated the role of trauma experiences, personality traits, and genotype in the maintenance of PTSD symptoms.

METHODS

In a previous large-scale epidemiological investigation 1 year after the Wenchuan earthquake, 215 children with PTSD symptoms were selected at random with their blood samples collected. All of them were followed up, and their PTSD symptoms were assessed 3 years later. The adolescent version of the UCLA PTSD Reaction Index, the earthquake exposure scale, and the Junior Eysenck Personality Questionnaire were used to determine PTSD symptoms, trauma experiences, and personality traits, respectively. We sequenced candidate genes involved in the regulation of long-term potentiation via NMDA-type receptors to identify the related SNP variations.

RESULTS

Being trapped for a longer period of time, feeling one's own or a family member's life to be in danger, losing a close family member or friend, extraversion, neuroticism, TrkB, G72 and CNTF were found to be associated with the maintenance of PTSD symptoms.

CONCLUSIONS

Experiences, personality traits, and genotype influenced the maintenance of PTSD in child survivors who were considered to be followed up without medicine. This result could help to identify potential targets for treatment and promote the rational allocation of medical resources.

Predictors of outcome during inpatient psychotherapy for posttraumatic stress disorder: a single-treatment, multi-site, practice-based study

Objective: The aims of this study were to determine the effectiveness of a routine clinical care treatment and to identify predictors of treatment outcome in PTSD inpatients. Methods: A routinely collected data set of 612 PTSD inpatients (M = 42.3 years [SD = 11.6], 75.7% female) having received trauma-focused psychotherapy was analyzed. Primary outcome was the clinical symptom severity change score, secondary outcomes were assessed using functional, anxiety, and depression change scores. Hedges g-corrected pre-post effect sizes (ES) were computed for all outcomes. Elastic net regulation as a data-driven, stability-based machine-learning approach was used to build stable clinical prediction models. Results: Hedges g ES indicated medium to large effects on all outcomes. The results of the predictor analyses suggested that a combined predictor model with sociodemographic, clinical, and psychometric variables contribute to predicting different treatment outcomes. Across the clinical and functional outcome, psychoticism, total number of diagnoses, and bronchial asthma consistently showed a stable negative predictive relationship to treatment outcome. Conclusion: Trauma-focused psychotherapy could effectively be implemented in a routine inpatient setting. Some important prognostic variables could be identified. If the proposed models of predictors are replicated, they may help personalize treatment for patients receiving routine clinical care.

The effectiveness of psychological interventions for post-traumatic stress disorder in children, adolescents and young adults: a systematic review and meta-analysis

BACKGROUND

Children and adolescents display different symptoms of post-traumatic stress disorder (PTSD) than adults. Whilst evidence for the effectiveness of psychological interventions has been synthesised for adults, this is not directly applicable to younger people. Therefore, this systematic review and meta-analysis synthesised studies investigating the effectiveness of psychological interventions for PTSD in children, adolescents and young adults. It provides an update to previous reviews investigating interventions in children and adolescents, whilst investigating young adults for the first time.

METHODS

We searched published and grey literature to obtain randomised control trials assessing psychological interventions for PTSD in young people published between 2011 and 2019. Quality of studies was assessed using the Cochrane Risk of Bias tool. Data were analysed using univariate random-effects meta-analysis.

RESULTS

From 15 373 records, 27 met criteria for inclusion, and 16 were eligible for meta-analysis. There was a medium pooled effect size for all psychological interventions (d = -0.44, 95% CI -0.68 to -0.20), as well as for Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) and Eye Movement Desensitisation and Reprocessing (EMDR) (d = -0.30, 95% CI -0.58 to -0.02); d = -0.46, 95% CI -0.81 to -0.12).

CONCLUSIONS

Some, but not all, psychological interventions commonly used to treat PTSD in adults were effective in children, adolescents and young adults. Interventions specifically adapted for younger people were also effective. Our results support the National Institute for Health and Care Excellence guidelines which suggest children and adolescents be offered TF-CBT as a first-line treatment because of a larger evidence base, despite EMDR being more effective.

An Open Label Pilot Study of a Brief Psychosocial Intervention for Disaster and Trauma Survivors

BACKGROUND

In the aftermath of disaster, a large proportion of people will develop psychosocial difficulties that impair recovery, but for which presentations do not meet threshold criteria for disorder. Although these adjustment problems can cause high distress and impairment, and often have a trajectory towards mental health disorder, few evidence-based interventions are available to facilitate recovery.

OBJECTIVE

This paper describes the development and pilot testing of an internationally developed, brief, and scalable psychosocial intervention that targets distress and poor adjustment following disaster and trauma.

METHOD

The Skills fOr Life Adjustment and Resilience (SOLAR) program was developed by an international collaboration of trauma and disaster mental health experts through an iterative expert consensus process. The resulting five session, skills-based intervention, deliverable by community-based or frontline health or disaster workers with little or no formal mental health training (known as coaches), was piloted with 15 Australian bushfire survivors using a pre-post with follow up, mixed-methods design study.

RESULTS

Findings from this pilot demonstrated that the SOLAR program was safe and feasible for non-mental health frontline workers (coaches) to deliver locally after two days of training. Participants' attendance rates and feedback about the program indicated that the program was acceptable. Pre-post quantitative analysis demonstrated reductions in psychological distress, posttraumatic stress symptoms, and impairment.

CONCLUSIONS

This study provides preliminary evidence that the delivery of the SOLAR program after disaster by trained, frontline workers with little or no mental health experience is feasible, acceptable, safe, and beneficial in reducing psychological symptoms and impairment among disaster survivors. Randomized controlled trials of the SOLAR program are required to advance evidence of its efficacy.

Mobile Apps for Post Traumatic Stress Disorder

Post Traumatic Stress Disorder (PTSD) is a serious mental disorder that is caused by exposure to traumatic stress and not being able to recover from it. PTSD often results in a severe reduction of the quality of life, and is significantly associated with the risk of suicide. This paper identifies the current list of free mobile applications (apps) available in Android platform for smartphone users with PTSD. This paper also assesses the functionalities of the apps selected. The result of this study may assist PTSD apps seekers for self-support, and serve as a reference for researchers and developers, who intend proposing stress management apps.

Changes in Traumatic Memories and Posttraumatic Cognitions Associate with PTSD Symptom Improvement in Treatment of Multiply Traumatized Children and Adolescents

Refinement, targeting, and better dissemination of trauma-focused therapies requires understanding their underlying mechanisms of change. Research on such mechanisms among multiply traumatized children and adolescents is scarce. We examined the role of improvements in problematic qualities of traumatic memories and maladaptive posttraumatic cognitions in PTSD symptom reduction, in a randomized, pragmatic trial of narrative exposure therapy vs. treatment as usual with 40 participants 9-17 years old (48% female, 75% refugee background) repeatedly exposed to war or family violence related trauma. Posttraumatic cognitions, quality of traumatic memories and PTSD symptoms were assessed by self-report before and after treatment. Improvements in both quality of traumatic memories (r _MI = .36) and posttraumatic cognitions (r _MI = .46) correlated with symptom reduction. However, improvement during treatment was only significant for quality of traumatic memories (F _MI(11,333.56) = 4.77), not for posttraumatic cognitions. We detected no difference in effects of narrative exposure therapy and treatment as usual on cognitions or memories. We tentatively suggest problematic, overly sensory and incoherent quality of traumatic memories may be a useful target in the treatment of PTSD symptoms among multiply traumatized children and adolescents. Changing maladaptive posttraumatic cognitions, though important, may be challenging among those with severe, repeated trauma.

Changing the Adult State of Mind With Respect to Attachment: An Exploratory Study of the Role of EMDR Psychotherapy

We aimed to assess changes in the attachment internal working model and reflective function (RF) as mechanisms of change in eye movement desensitization and reprocessing (EMDR) treatment for patients with traumatic memories. Twenty adult female patients with parenting and relational problems participated in the study. Attachment organization was assessed with the Adult Attachment Interview (AAI) and the RF coding scale pre- and posttreatment. We found that EMDR therapy increased patients' narrative coherence and RF. We noted a significant decrease in the number of participants classified as unresolved following the course of EMDR treatment in which loss and/or trauma were resolved. This article summarizes the changes after EMDR therapy regarding attachment status and its efficacy to reprocess early traumatic memories in a more adaptive way. Finally, our results also support the usefulness of the AAI as a tool for understanding the changing processes during a therapeutic treatment.

Self-handicapping among nursing students: an interventional study

BACKGROUND

Self-handicapping is an effective defense strategy in an individual's behavior that leads to weak performance in different situations like education. This study aimed to investigate how training problem solving skills affected the rate of self-handicapping among nursing students.

METHODS

This interventional study was done in Jahrom, Fars province, Iran during 2016-2017. Totally, 90 nursing students were selected among those admitted from 2013 to 2016 using stratified sampling. Then, the students were randomly divided into a control and an intervention group each including 45 participants. Teaching problem solving skills to the intervention group was completed over six sessions each lasting for two hours. The students' rate of self-handicapping was evaluated based on the scores obtained in Jones and Rodwalt's self-management questionnaire before and after the intervention (immediately and one month later). The data were entered into the SPSS statistical software, version 16 and were analyzed using descriptive and inferential statistics, including t-test, chi-square, and repeated measures ANOVA. The significance level was set at 0.05.

RESULTS

The findings revealed a significant difference in the intervention group's self-handicapping scores before and after the intervention (p < 0.001). However, no significant change was observed in this regard in the control group (p = 0.575). The results indicated no significant differences between the intervention and control groups concerning the mean score of self-handicapping immediately after the intervention (p = 0.761). However, a significant difference was detected between the two groups in this regard one month after the intervention (p = 0.014).

CONCLUSION

Teaching problem solving skills influenced the students' beliefs and performances positively and led to a decrease in their self-handicapping. Thus, teaching cognitive-behavioral approaches is recommended to be considered among the ten life skills used in curricular design for medical students, including nurses.

Posttraumatic stress disorder following the 2008 Wenchuan earthquake: A 10-year systematic review among highly exposed populations in China

BACKGROUND

The 2008 Wenchuan earthquake was unprecedented in Chinese history both in terms of the magnitude of the quake itself and the scale of human suffering. Following the disaster, researchers reported on a wide range of mental health outcomes, especially posttraumatic stress disorder (PTSD). In this review, we assess the cumulative body of research evidence about PTSD across the first 10 years following the earthquake.

METHODS

We searched the literature in the PubMed, Web of Science, and China National Knowledge Infrastructure (CNKI) databases (from May 2008 to February 2018) using Wenchuan earthquake and PTSD as keywords.

RESULTS

We selected 58 relevant studies. Published findings from the selected period suggested a substantial burden of PTSD on highly exposed survivors. Studies have found that symptoms of PTSD have been associated with a range of risk factors, including sociodemographic factors, trauma exposure characteristics, post-disaster cognitive and emotional states, and social support. Studies have explored the factor structure of PTSD in the affected Chinese population, and researchers have developed a Chinese self-report measure of PTSD symptoms. Several treatments for PTSD have been evaluated, including some indigenous intervention methods.

LIMITATIONS

Only a relatively small number of the studies used longitudinal assessments, and the consistency and effectiveness of measurement tools for PTSD require further exploration. More rigorous investigations of the effectiveness of interventions for the prevention and treatment of PTSD are needed.

CONCLUSION

The 10-year body of literature is important for the future deployment of disaster relief and an increased understanding of PTSD in China.

Posttraumatic stress disorder: a model of the longitudinal course and the role of risk factors

Posttraumatic stress disorder (PTSD) differs from other anxiety disorders in that experience of a traumatic event is necessary for the onset of the disorder. The condition runs a longitudinal course, involving a series of transitional states, with progressive modification occurring with time. Notably, only a small percentage of people that experience trauma will develop PTSD. Risk factors, such as prior trauma, prior psychiatric history, family psychiatric history, peritraumatic dissociation, acute stress symptoms, the nature of the biological response, and autonomic hyperarousal, need to be considered when setting up models to predict the course of the condition. These risk factors influence vulnerability to the onset of PTSD and its spontaneous remission. In the majority of cases, PTSD is accompanied by another condition, such as major depression, an anxiety disorder, or substance abuse. This comorbidity can also complicate the course of the disorder and raises questions about the role of PTSD in other psychiatric conditions. This article reviews what is known about the emergence of PTSD following exposure to a traumatic event using data from clinical studies.

de Quervain D, Elbert T, Kolassa S, Kolassa IT. Genetic variation is associated with PTSD risk and aversive memory: Evidence from two trauma-Exposed African samples and one healthy European sample

The probability to develop posttraumatic stress disorder (PTSD), characterized by vivid, intrusive emotional memories of the encountered traumatic events, depends - among other factors - on the number of previous traumatic experiences (traumatic load) and individual genetic vulnerability. So far, our knowledge regarding the biological underpinnings of PTSD is relatively sparse. Genome-wide association studies (GWAS) followed by independent replication might help to discover novel, so far unknown biological mechanisms associated with the development of traumatic memories. Here, a GWAS was conducted in N = 924 Northern Ugandan rebel war survivors and identified seven suggestively significant single nucleotide polymorphisms (SNPs; p ≤ 1 × 10^-5) for lifetime PTSD risk. Of these seven SNPs, the association of rs3852144 on chromosome 5 was replicated in an independent sample of Rwandan genocide survivors (N = 370, p < .01). While PTSD risk increased with accumulating traumatic experiences, the vulnerability was reduced in carriers of the minor G-allele in an additive manner. Correspondingly, memory for aversive pictures decreased with higher number of the minor G-allele in a sample of N = 2698 healthy Swiss individuals. Finally, investigations on N = 90 PTSD patients treated with Narrative Exposure Therapy indicated an additive effect of genotype on PTSD symptom change from pre-treatment to four months after treatment, but not between pre-treatment and the 10-months follow-up. In conclusion, emotional memory formation seems to decline with increasing number of rs3852144 G-alleles, rendering individuals more resilient to PTSD development. However, the impact on therapy outcome remains preliminary and further research is needed to determine how this intronic marker may affect memory processes in detail.

First-line therapy for post-traumatic stress disorder: A systematic review of cognitive behavioural therapy and psychodynamic approaches

BACKGROUND

Despite evidence supporting cognitive behavioural therapy (CBT)-based interventions as the most effective approach for treating post-traumatic stress disorder (PTSD) in randomised control trials, alternative treatment interventions are often used in clinical practice. Psychodynamic (PDT)-based interventions are one example of such preferred approaches, this is despite comparatively limited available evidence supporting their effectiveness for treating PTSD.

AIMS

Existing research exploring effective therapeutic interventions for PTSD includes trauma-focused CBT involving exposure techniques. The present review sought to establish the treatment efficacy of CBT and PDT approaches and considers the potential impact of selecting PDT-based techniques over CBT-based techniques for the treatment of PTSD.

RESULTS

The evidence reviewed provided examples supporting PDT-based therapy as an effective treatment for PTSD, but confirmed CBT as more effective in the treatment of this particular disorder. Comparable dropout rates were reported for both treatment approaches, suggesting that relative dropout rate should not be a pivotal factor in the selection of a PDT approach over CBT for treatment of PTSD.

CONCLUSION/IMPLICATIONS

The need to routinely observe evidence-based recommendations for effective treatment of PTSD is highlighted and factors undermining practitioner engagement with CBT-based interventions for the treatment of PTSD are identified.

Eye movement desensitization and reprocessing as a treatment for PTSD: current neurobiological theories and a new hypothesis

Eye movement desensitization and reprocessing (EMDR), a form of psychotherapy for individuals with post-traumatic stress disorder (PTSD), has long been a controversial topic, hampered in part by a lack of understanding of the neural mechanisms that contribute to its remedial effect. Here, we review current theories describing EMDR's potential neurobiological mechanisms of action involving working memory, interhemispheric communication, de-arousal, and memory reconsolidation. We then discuss recent studies describing the temporal and spatial aspects of smooth pursuit and predictive saccades, which resemble those made during EMDR, and their neural correlates within the default mode network (DMN) and cerebellum. We hypothesize that if the production of bilateral predictive eye movements is supportive of DMN and cerebellum activation, then therapies that shift the brain towards this state correspondingly would benefit the processes regulated by these structures (i.e., memory retrieval, relaxation, and associative learning), all of which are essential components for PTSD recovery. We propose that the timing of sensory stimulation may be relevant to treatment effect and could be adapted across different patients depending on their baseline saccade metrics. Empirical data in support of this model are reviewed and experimental predictions are discussed.

Individual treatment selection for patients with posttraumatic stress disorder

BACKGROUND

Trauma-focused cognitive behavioral therapy (Tf-CBT) and eye movement desensitization and reprocessing (EMDR) are two highly effective treatment options for posttraumatic stress disorder (PTSD). Yet, on an individual level, PTSD patients vary substantially in treatment response. The aim of the paper is to test the application of a treatment selection method based on a personalized advantage index (PAI).

METHOD

The study used clinical data for patients accessing treatment for PTSD in a primary care mental health service in the north of England. PTSD patients received either EMDR (N = 75) or Tf-CBT (N = 242). The Patient Health Questionnaire (PHQ-9) was used as an outcome measure for depressive symptoms associated with PTSD. Variables predicting differential treatment response were identified using an automated variable selection approach (genetic algorithm) and afterwards included in regression models, allowing the calculation of each patient's PAI.

RESULTS

Age, employment status, gender, and functional impairment were identified as relevant variables for Tf-CBT. For EMDR, baseline depressive symptoms as well as prescribed antidepressant medication were selected as predictor variables. Fifty-six percent of the patients (n = 125) had a PAI equal or higher than one standard deviation. From those patients, 62 (50%) did not receive their model-predicted treatment and could have benefited from a treatment assignment based on the PAI.

CONCLUSIONS

Using a PAI-based algorithm has the potential to improve clinical decision making and to enhance individual patient outcomes, although further replication is necessary before such an approach can be implemented in prospective studies.

Treatment expectancy, working alliance, and outcome of Trauma-Focused Cognitive Behavioral Therapy with children and adolescents

BACKGROUND

It has been shown that positive treatment expectancy (TE) and good working alliance increase psychotherapeutic success in adult patients, either directly or mediated by other common treatment factors like collaboration. However, the effects of TE in psychotherapy with children, adolescents and their caregivers are mostly unknown. Due to characteristics of the disorder such as avoidant behavior, common factors may be especially important in evidence-based treatment of posttraumatic stress symptoms (PTSS), e.g. for the initiation of exposure based techniques.

METHODS

TE, collaboration, working alliance and PTSS were assessed in 65 children and adolescents (age M = 12.5; SD = 2.9) and their caregivers. Patients' and caregivers' TE were assessed before initiation of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT). Patients' and caregivers' working alliance, as well as patients' collaboration were assessed at mid-treatment, patients' PTSS at pre- and post-treatment. Path analysis tested both direct and indirect effects (by collaboration and working alliance) of pre-treatment TE on post-treatment PTSS, and on PTSS difference scores.

RESULTS

Patients' or caregivers' TE did not directly predict PTSS after TF-CBT. Post-treatment PTSS was not predicted by patients' or caregivers' TE via patients' collaboration or patients' or caregivers' working alliance. Caregivers' working alliance with therapists significantly contributed to the reduction of PTSS in children and adolescents (post-treatment PTSS: β = - 0.553; p < 0.001; PTSS difference score: β = 0.335; p = 0.031).

CONCLUSIONS

TE seems less important than caregivers' working alliance in TF-CBT for decreasing PTSS. Future studies should assess TE and working alliance repeatedly during treatment and from different perspectives to understand their effects on outcome. The inclusion of a supportive caregiver and the formation of a good relationship between therapists and caregivers can be regarded as essential for treatment success in children and adolescents with PTSS.

Meta-analysis of interventions for posttraumatic stress disorder and depression in adult survivors of mass violence in low- and middle-income countries

BACKGROUND

Most survivors of mass violence live in low- and middle-income countries (LMICs). We conducted a meta-analysis of randomized controlled psychotherapy trials for adult posttraumatic stress disorder (PTSD) and/or depression in LMICs.

METHODS

We included 18 clinical trials (3,058 participants), in which 25 and 18 treatment arms measured symptoms of PTSD and depression, respectively.

RESULTS

Active treatments for PTSD yielded a large aggregated pre-post effect size (g = 1.29; 95% CI = [0.99; 1.59]) and a small to medium effect size at posttreatment when compared to control conditions (g = 0.39; 95% CI = [0.24; 0.55]). Effect sizes were similar for pretreatment versus follow-up (g = 1.75; 95% CI = [1.17; 2.32]) and in comparison to waitlist at follow-up (g = 0.93; 95% CI = [0.56; 1.31]). Active treatments for depression produced large pre-post (g = 1.28; 95% CI = [0.96; 1.61]) and controlled effect sizes (posttreatment, comparison to control conditions, g = 0.86; 95% CI = [0.54; 1.18]).

CONCLUSIONS

Our findings suggest that psychological interventions can effectively reduce symptoms of PTSD and depression in LMICs. Future research needs to focus on cost-effective interventions that are likely to be disseminated to the large numbers of war survivors in LMICs.

Bridging the Gaps Between Basic Science and Cognitive-Behavioral Treatments for Anxiety Disorders in Routine Care

Abstract. As a core component of cognitive-behavioral therapies (CBT), behavioral exposure is an effective treatment for anxiety disorders. Still, recent treatment studies demonstrate relatively high rates of treatment dropout, nonresponse, and relapse, indicating a substantial need for optimizing and personalizing existing treatment procedures. In the present article, we aim to address current challenges and future demands for translational research in CBT for the anxiety disorders, including (a) a better understanding of those mechanisms conferring behavioral change, (b) identifying important sources of individual variation that may act as moderators of treatment response, and (c) targeting practical barriers for dissemination of exposure therapy to routine care. Based on a recursive process model of psychotherapy research we will describe distinct steps to systematically translate basic and clinical research “from bench to bedside” to routine care, but also vice versa. Some of these aspects may stimulate the future roadmap for evidence-based psychotherapy research in order to better target the treatment of anxiety disorders as one core health challenge of our time.

'Geraniums (red) and Delphiniums (blue)': Trauma, Ethics, and Medical Communications

More official complaints about medical treatment in the UK relate to poor communications than to wrong diagnoses. This article, in considering the importance of communications training for clinicians, is structured into three sections. From use of a story that introduces the idea of miscommunication and trauma in the first section, the article moves, in the second, to a theorisation of trauma as a concept, addressing issues of intersubjectivity, the relationship between embodied and psychological being, and ethics. From this, the third section engages directly with medical communications training, exemplifying a particular literary-studies approach to matters of communication.

Cognitive Processing Therapy for the Treatment of Acute Stress Disorder Following Sexual Assault: A Randomised Effectiveness Study

The effectiveness of individually administered cognitive processing therapy (CPT) when compared with treatment as usual (TAU) in a community sexual assault centre was tested. Trauma survivors with acute stress disorder (ASD) following sexual assault were randomised to either CPT (n = 25) or TAU (n = 22), and assessed at pretreatment, posttreatment, and 3-, 6- and 12-month follow-up. Both groups demonstrated large reductions in PTSD and depression symptoms following treatment, and these gains were maintained over the course of follow-ups (Cohen's ds for PTSD symptom reductions ranging between 0.76 to 1.45). Although smaller and not always consistent, between-group effect sizes typically favoured CPT. Effect sizes (d) ranged between 0.13–0.50 for posttraumatic stress and 0.13–0.41 for depression over the course of follow-ups. Independent assessment of PTSD severity indicated more CPT participants reached good end-state functioning at 12-month follow-up (50%) than TAU (31%). Although both treatments were effective, there were some indications that CPT led to better outcomes relative to therapists delivering their usual therapy. The present study demonstrates that evidence-based, trauma-focused therapy such as CPT can be effective when delivered as an early intervention in a routine mental health setting.

Psychological interventions for post-traumatic stress disorder (PTSD) in people with severe mental illness

BACKGROUND

Increasing evidence indicates that individuals who develop severe mental illness (SMI) are also vulnerable to developing post-traumatic stress disorder (PTSD), due to increased risk of exposure to traumatic events and social adversity. The effectiveness of trauma-focused psychological interventions (TFPIs) for PTSD in the general population is well-established. TFPIs involve identifying and changing unhelpful beliefs about traumatic experiences, processing of traumatic memories, and developing new ways of responding to cues associated with trauma. Little is known about the potential feasibility, acceptability and effectiveness of TFPIs for individuals who have a SMI and PTSD.

OBJECTIVES

To evaluate the effectiveness of psychological interventions for PTSD symptoms or other symptoms of psychological distress arising from trauma in people with SMI.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group's Trials Study-Based Register (up until March 10, 2016), screened reference lists of relevant reports and reviews, and contacted trial authors for unpublished and/or specific outcome data.

SELECTION CRITERIA

We included all relevant randomised controlled trials (RCTs) which investigated TFPIs for people with SMI and PTSD, and reported useable data.

DATA COLLECTION AND ANALYSIS

Three review authors (DS, MF, IN) independently screened the titles and abstracts of all references identified, and read short-listed full text papers. We assessed risk of bias in each case. We calculated the risk ratio (RR) and 95% confidence interval (CI) for binary outcomes, and the mean difference (MD) and 95% CI for continuous data, on an intention-to-treat basis. We assessed quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and created 'Summary of findings' tables.

MAIN RESULTS

Four trials involving a total of 300 adults with SMI and PTSD are included. These trials evaluated three active intervention therapies: trauma-focused cognitive behavioural therapy (TF-CBT), eye movement desensitisation and reprocessing (EMDR), and brief psychoeducation for PTSD, all delivered via individual sessions. Our main outcomes of interest were PTSD symptoms, quality of life/well-being, symptoms of co-morbid psychosis, anxiety symptoms, depressive symptoms, adverse events and health economic outcomes. 1. TF-CBT versus usual care/waiting list Three trials provided data for this comparison, however, continuous outcome data available were more often found to be skewed than unskewed, leading to the necessity of conducting analyses separately for the two types of continuous data. Using the unskewed data only, results showed no significant differences between TF-CBT and usual care in reducing clinician-rated PTSD symptoms at short term (1 RCT, n =13, MD 13.15, 95% CI -4.09 to 30.39,low-quality evidence). Limited unskewed data showed equivocal results between groups in terms of general quality of life (1 RCT, n = 39, MD -0.60, 95% CI -4.47 to 3.27, low-quality evidence), symptoms of psychosis (1 RCT, n = 9, MD -6.93, 95% CI -34.17 to 20.31, low-quality evidence), and anxiety (1 RCT, n = 9, MD 12.57, 95% CI -5.54 to 30.68, very low-quality evidence), at medium term. The only available data on depression symptoms were skewed and were equivocal across groups at medium term (2 RCTs, n = 48, MD 3.26, 95% CI -3.66 to 10.18, very low-quality evidence). TF-CBT was not associated with more adverse events (1 RCT, n = 100, RR 0.44, 95% CI 0.09 to 2.31, low-quality evidence) at medium term. No data were available for health economic outcomes. Very limited data for PTSD and other symptoms were available over the long term. 2. EMDR versus waiting listOne trial provided data for this comparison. Favourable effects were found for EMDR in terms of PTSD symptom severity at medium term but data were skewed (1 RCT, n = 83, MD -12.31, 95% CI -22.72 to -1.90, very low-quality evidence). EMDR was not associated with more adverse events (1 RCT, n = 102, RR 0.21, 95% CI 0.02 to 1.85, low-quality evidence). No data were available for quality of life, symptoms of co-morbid psychosis, depression, anxiety and health economics.3. TF-CBT versus EMDROne trial compared TF-CBT with EMDR. PTSD symptom severity, based on skewed data (1 RCT, n = 88, MD -1.69, 95% CI -12.63 to 9.23, very low-quality evidence) was similar between treatment groups. No data were available for the other main outcomes.4. TF-CBT versus psychoeducationOne trial compared TF-CBT with psychoeducation. Results were equivocal for PTSD symptom severity (1 RCT, n = 52, MD 0.23, 95% CI -14.66 to 15.12, low-quality evidence) and general quality of life (1 RCT, n = 49, MD 0.11, 95% CI -0.74 to 0.95, low-quality evidence) by medium term. No data were available for the other outcomes of interest.

AUTHORS' CONCLUSIONS

Very few trials have investigated TFPIs for individuals with SMI and PTSD. Results from trials of TF-CBT are limited and inconclusive regarding its effectiveness on PTSD, or on psychotic symptoms or other symptoms of psychological distress. Only one trial evaluated EMDR and provided limited preliminary evidence favouring EMDR compared to waiting list. Comparing TF-CBT head-to-head with EMDR and brief psychoeducation respectively, showed no clear effect for either therapy. Both TF-CBT and EMDR do not appear to cause more (or less) adverse effects, compared to waiting list or usual care; these findings however, are mostly based on low to very low-quality evidence. Further larger scale trials are now needed to provide high-quality evidence to confirm or refute these preliminary findings, and to establish which intervention modalities and techniques are associated with improved outcomes, especially in the long term.

Systematic Review on Post-Traumatic Stress Disorder Among Survivors of the Wenchuan Earthquake

Post-traumatic stress disorder (PTSD) widely occurs among victims or witness of disasters. With flashbacks, hyperarousal, and avoidance being the typical symptoms, PTSD became a focus of psychological research. The earthquake in Wenchuan, China, on May 12, 2008, was without precedent in magnitude and aftermath and caused huge damage, which drew scientists' attention to mental health of the survivors. We conducted a systematic overview by collecting published articles from the PubMed database and classifying them into five points: epidemiology, neuropathology, biochemistry, genetics and epigenetics, and treatment. The large body of research during the past 6 years showed that adolescents and adults were among the most studied populations with high prevalence rates for PTSD. Genomic and transcriptomic studies focusing on gene × environment studies as well as epigenetics are still rare, although a few available data showed great potential to better understand the pathophysiology of PTSD as multifactorial disease. Phytotherapy with Chinese herbs and acupuncture are rarely reported as of yet, although the first published data indicated promising therapy effects. Future studies should focus on the following points: (1) The affected populations under observation should be better defined concerning individual risk factor, time of observation, spatial movement, and individual disease courses of patients. (2) The role of social support for prevalence rates of PTSD should be observed in more detail. (3) Efficacy and safety of Chinese medicine should be studied to find potential interventions and effective treatments of PTSD.

Internet-delivered cognitive therapy for PTSD: a development pilot series

BACKGROUND

Randomised controlled trials have established that face-to-face cognitive therapy for posttraumatic stress disorder (CT-PTSD) based on Ehlers and Clark's cognitive model of PTSD is highly effective and feasible with low rates of dropout. Access to evidence-based psychological treatments for PTSD is insufficient. Several studies have shown that therapist-assisted treatment delivery over the Internet is a promising way of improving access to cognitive behavioural therapy interventions.

OBJECTIVE

To develop an Internet version of CT-PTSD that significantly reduces therapist contact time without compromising treatment integrity or retention rates.

METHODS

We describe the development of an Internet version of CT-PTSD. It implements all the key procedures of face-to-face CT-PTSD, including techniques that focus on the trauma memory, such as memory updating, stimulus discrimination and revisiting the trauma site, as well as restructuring individually relevant appraisals relating to overgeneralisation of danger, guilt, shame or anger, behavioural experiments and planning activities to reclaim quality of life. A cohort of 10 patients meeting DSM-IV criteria for PTSD worked through the programme, with remote guidance from a therapist, and they were assessed at pre- and post-treatment on PTSD outcome, mood, work and social adjustment and process measures.

RESULTS

No patients dropped out. Therapists facilitated the treatment with 192 min of contact time per patient, plus 57 min for reviewing the patient's progress and messages. Internet-delivered CT-PTSD was associated with very large improvements on all outcome and process measures, with 80% of patients achieving clinically significant change and remission from PTSD.

CONCLUSIONS

Internet-delivered cognitive therapy for PTSD (iCT-PTSD) appears to be an acceptable and efficacious treatment. Therapist time was reduced to less than 25% of time in face-to-face CT-PTSD. Randomised controlled trials are required to evaluate systematically the acceptability and efficacy of iCT-PTSD.

How Do Adult Survivors of Childhood Sexual Abuse Experience Formally Delivered Talking Therapy? A Systematic Review

This systematic review explored how adult survivors of child sexual abuse experienced nonspecific and trauma-focused talking therapies. Following extensive systematic searches of academic databases, 23 qualitative empirical studies were chosen for review. Using a line-by-line thematic synthesis, four analytical themes developed. These themes were: The Therapeutic Process as a Means for Forming Connections, which discusses therapeutic relationships; Developing a Sense of Self Through the Therapeutic Processes, which identifies stages of developmental recovery; Therapeutic Lights and Black Holes in the Shadows of child sexual abuse, which reflects on how a history of child sexual abuse influenced experiences of therapy; and Healing or Harrowing: Connecting With Others and First-time Experiences, which explores what was helpful, hindering, and new throughout the therapeutic journey. Findings related to participants developing new options for interpersonal relationships through the experience of authentic trust and the experiential learning of control and choice. Recommendations are discussed in relation to developing therapeutic practice and future research.

Interventions for posttraumatic stress disorder: a review of the evidence base

Given high rates of trauma exposure in South Africa, mental health practitioners often need to deliver interventions to trauma survivors. While there have been few local trauma intervention studies, there is an extensive international evidence base that provides a rich resource on which to draw. This article reviews evidence-based treatments for posttraumatic stress disorder and complex posttraumatic stress disorder. The current weight of evidence supports the use of trauma-focused cognitive behavioural therapy approaches in the treatment of posttraumatic stress disorder and the use of multimodal, phase-based interventions to treat complex posttraumatic stress disorder. There is also a long-standing, though less extensive, evidence base for psychodynamic therapy in the treatment of these conditions, as well as a number of emerging treatment approaches that require further study. While there are some limitations to transferring these approaches to the South African context, the current evidence base provides valuable guidelines for local practitioners seeking to develop their competencies in treating posttraumatic stress disorder and more complex trauma-based presentations.

The relative efficacy of bona fide psychotherapies for post-traumatic stress disorder: a meta-analytical evaluation of randomized controlled trials

BACKGROUND

In the treatment of PTSD, meta-analyses suggest comparable efficacy of cognitive behavioural therapies and various trauma focused treatments, but results for other treatments are inconsistent. One meta-analysis found no differences for bona fide therapies, but was critizised for overgeneralization and a biased study sample and relied on an omnibus test of overall effect size heterogeneity that is not widely used.

METHODS

We present an updated meta-analysis on bona fide psychotherapies for PTSD, contrasting an improved application of the omnibus test of overall effect size heterogeneity with conventional random-effects meta-analyses of specified treatment types against all others. Twenty-two studies were eligible, reporting 24 head-to-head comparisons in randomized controlled trials of 1694 patients.

RESULTS

Head-to-head comparison between trauma focused and non-trauma focused treatments revealed a small relative advantage for trauma focused treatments at post-treatment (Hedges' g = 0.14) and at two follow-ups (g = 0.17, g = 0.23) regarding PTSD symptom severity. Controlling and adjusting for influential studies and publication bias, prolonged exposure and exposure therapies (g = 0.19) were slightly more efficacious than other therapies regarding PTSD symptom severity at post-treatment; prolonged exposure had also higher recovery rates (RR = 1.26). Present-centered therapies were slightly less efficacious regarding symptom severity at post-treatment (g = -0.20) and at follow-up (g = -0.17), but equally efficacious as available comparison treatments with regards to secondary outcomes. The improved omnibus test confirmed overall effect size heterogeneity.

CONCLUSIONS

Trauma focused treatments, prolonged exposure and exposure therapies were slightly more efficacious than other therapies in the treatment of PTSD. However, treatment differences were at most small and far below proposed thresholds of clinically meaningful differences. Previous null findings may have stemmed from not clearly differentiating primary and secondary outcomes, but also from a specific use of the omnibus test of overall effect size heterogeneity that appears to be prone to error. However, more high-quality studies using ITT analyses are still needed to draw firm conclusions. Moreover, the PTSD treatment field may need to move beyond a focus primarily on efficacy so as to address other important issues such as public health issues and the requirements of highly vulnerable populations.

Complex PTSD and phased treatment in refugees: a debate piece

BACKGROUND

Asylum seekers and refugees have been claimed to be at increased risk of developing complex posttraumatic stress disorder (complex PTSD). Consequently, it has been recommended that refugees be treated with present-centred or phased treatment rather than stand-alone trauma-focused treatment. This recommendation has contributed to a clinical practice of delaying or waiving trauma-focused treatment in refugees with PTSD.

OBJECTIVE

The aim of this debate piece is to defend two theses: (1) that complex trauma leads to complex PTSD in a minority of refugees only and (2) that trauma-focused treatment should be offered to all refugees who seek treatment for PTSD.

METHODS

The first thesis is defended by comparing data on the prevalence of complex PTSD in refugees to those in other trauma-exposed populations, using studies derived from a systematic review. The second thesis is defended using conclusions of systematic reviews and a meta-analysis of the efficacy of psychotherapeutic treatment in refugees.

RESULTS

Research shows that refugees are more likely to meet a regular PTSD diagnosis or no diagnosis than a complex PTSD diagnosis and that prevalence of complex PTSD in refugees is relatively low compared to that in survivors of childhood trauma. Effect sizes for trauma-focused treatment in refugees, especially narrative exposure therapy (NET) and culturally adapted cognitive-behaviour therapy (CA-CBT), have consistently been found to be high.

CONCLUSIONS

Complex PTSD in refugees should not be assumed to be present on the basis of complex traumatic experiences but should be carefully diagnosed using a validated interview. In line with treatment guidelines for PTSD, a course of trauma-focused treatment should be offered to all refugees seeking treatment for PTSD, including asylum seekers.
