A guide to guidelines for the treatment of posttraumatic stress disorder in adults: An update

Enduring intensity for healing: the patient perspective of intensive outpatient treatment for PTSD

BACKGROUND

Prolonged exposure is widely regarded as a first-line treatment for alleviating symptoms of post-traumatic stress disorder (PTSD); however, it is often associated with high dropout rates and may not always be sufficiently efficacious. Intensified treatment has been suggested as a solution to increase treatment efficacy and reduce dropout rates, but little is known about patients' preferences for this type of treatment.

OBJECTIVE

To investigate patients' experiences of prolonged exposure delivered in an intensive format (iPE).

METHOD

Semi-structured interviews were conducted with 12 participants after completion of iPE.

RESULTS

Thematic analysis of the data yielded one overarching theme 'Brutal Yet Worth It,' accompanied by five subthemes: Building Blocks of Commitment, Strength through collective support, Overcoming challenges of the intensive treatment week, Therapeutic gains of the intensive treatment, and Facilitating and Enabling Treatment Progress. The participants described short-term discomfort and demands, contrasted with the recognition of substantial benefits that extended beyond PTSD symptom reduction. The interplay of individual attributes and experience of social support emerged as crucial factors shaping the experience.

CONCLUSIONS

Participants described the iPE experience as intense and demanding, yet transformative and worthwhile in the interviews. These findings highlight the complex and multifaceted experiences of patients undergoing PE delivered in an intensive format. The findings could offer valuable insights for designing more well-received PTSD treatments, leading to enhancements in the overall quality of intensified treatment approaches.

Helpful but not enough: exploring participants' experiences of a digital therapist-guided prolonged exposure treatment for PTSD

Background: Post-traumatic stress disorder (PTSD) can be a severe psychiatric condition, and access to timely evidence-based treatment is often limited. Prolonged exposure is recommended as first line treatment in clinical guidelines. There is limited research on how digital formats of prolonged exposure used to increase treatment availability impact user experience. Therefore, we wanted to investigate patients' experiences of prolonged exposure in a therapist-guided internet-delivered format (HOPE; Huddinge Online Prolonged Exposure), as part of an uncontrolled feasibility study.Method: Semi-structured interviews were conducted with a total of 14 participants upon their completion of HOPE.Results: Thematic analysis revealed that participants found HOPE to be helpful and effective, especially valuing the flexibility in the digital treatment format. However, a subset of participants reported that HOPE did not meet their needs entirely, indicating room for improvement and tailoring of treatment to individual preferences and needs.Conclusion: This study represents the first exploration of internet-delivered prolonged exposure therapy within a Swedish psychiatric setting, comprising participants characterized by moderate to severe PTSD and self-rated complex PTSD. The results could help guide the development of more accessible and acceptable treatments for PTSD, ultimately improving treatment quality.

Sudden gains in cognitive processing therapy with and without behavioral activation among service members with comorbid PTSD and MDD

Sudden gains-large, rapid, and stable symptom reductions during treatment-are associated with better patient outcomes. Little is known about sudden gains among patients with co-occurring posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), yet better understanding of sudden gains in this population may improve treatment of this comorbidity. This study evaluated sudden gains in PTSD and depression symptoms and their association with treatment outcomes among active duty service members with comorbid PTSD and MDD (N = 94) who were randomized to behavioral activation-enhanced cognitive processing therapy (BA + CPT) or CPT alone. Outcomes were interviewer-rated PTSD and depression severity at posttreatment and 3-month follow-up. PTSD and depression sudden gains occurred in 19 % and 27 % of the sample, respectively. Multilevel modeling showed sudden gains in depression symptoms were associated with clinically and statistically significant improvements in PTSD (p < .001) and depression severity (p < .001) outcomes. PTSD sudden gains were not associated with PTSD (p = .137) or depression (p = .187) outcomes. Improvements in both PTSD and depression outcomes following sudden depression gains may highlight the importance of depression symptom change during treatment as a prognostic marker of outcomes in this comorbid population.

Using machine learning methods to predict the outcome of psychological therapies for post-traumatic stress disorder: A systematic review

BACKGROUND

A number of treatments are available for post-traumatic stress disorder (PTSD), however, there is currently a lack of data-driven treatment selection and adaptation methods for this condition. Machine learning (ML) could potentially help to improve the prediction of treatment outcomes and enable precision mental healthcare in practice.

OBJECTIVES

To systematically review studies that applied ML methods to predict outcomes of psychological therapy for PTSD in adults (e.g., change in symptoms, dropout rate), and evaluate their methodological rigour.

METHODS

This was a pre-registered systematic review (CRD42022325021), which synthesised eligible clinical prediction studies found across four research databases. Risk of bias was assessed using the PROBAST tool. Study methods and findings were narratively synthesised, and adherence to ML best practice evaluated.

RESULTS

Seventeen studies met the inclusion criteria, including samples derived from experimental and observational study designs. All studies were assessed as having a high risk of bias, notably due to inadequately powered samples and a lack of sample size calculations. Training sample size ranged from N < 36-397. The studies applied a diverse range of ML methods such as decision trees, ensembling and boosting techniques. Five studies used unsupervised ML methods, while others used supervised ML. There was an inconsistency in the reporting of hyperparameter tuning and cross-validation methods. Only one study performed external validation.

CONCLUSIONS

ML has the potential to advance precision psychotherapy for PTSD, but to enable this, ML methods must be applied with greater adherence to best practice guidelines.

A summary review of the development of using a brief imagery-competing task intervention (ICTI) for reducing intrusive memories of psychological trauma: applications in healthcare settings for both staff and patients

Psychological trauma for those utilising and delivering healthcare is common, and in particular the experience of repeated and unwanted intrusive memories (IM) of the trauma can occur. There are several psychological interventions that have been shown to be effective with the full syndrome of Post Traumatic Stress Disorder (PTSD), but researchers have only recently explored targeted interventions for IMs. This review provides a summary of a body of work on a behavioural technique called "Imagery Competing Task Intervention" (ICTI) for intrusive memories after trauma by Holmes and colleagues. The papers presented outline the underlying cognitive science, the historical development of the intervention, and its application to various different populations in healthcare settings including clinical tests of efficacy. Settings and populations include traumatic events experienced by emergency department patients and emergency caesarean section patients, as well as after work-related trauma experienced by intensive care staff and wider healthcare staff. Timing of ICTI intervention delivery has included the same day of trauma, within 72 h and for older memories weeks, months (or years) post-trauma. The intervention has been delivered with a guided session, which in some studies is in person and some remotely via digital health application. There is a brief overview of other related interventions. The ICTI approach shows potential scalability in trauma laden environments such as healthcare, where exposure is unlikely to be limited or managed and symptoms such as subclinical IMs are common. As such the intervention could be used in a preventing-and-treating approach and in subclinical-to-clinical samples who have IMs after exposure to psychological trauma. Future research would be needed to test ICTI as an intervention for the full syndrome of PTSD.

Reliable symptom worsening among veterans receiving cognitive processing therapy or prolonged exposure therapy for posttraumatic stress disorder in routine VHA care

Clinical practice guidelines recommend trauma-focused evidence-based psychotherapy (EBP) to treat posttraumatic stress disorder (PTSD). Some veterans and clinicians report concerns that discussion of trauma will make PTSD symptoms worse. We studied the frequency and correlates of reliable symptom worsening during PTSD EBPs in routine clinical practice. Using national electronic health record data from the Veterans Health Administration, we identified veterans (n = 25,768) who initiated PTSD EBP between 1/2018-1/2023 and had PTSD symptom measurements (i.e., PTSD Checklist for DSM-5; PCL-5). We defined reliable symptom worsening as a 10-point PCL-5 increase from baseline. Using hierarchical Bayesian zero inflated binomial logistic regression, we modeled the probability of experiencing reliable symptom worsening across demographic, military, clinical and service delivery characteristics. In our sample, 22.9 % of veterans experienced reliable symptom worsening. However, most demographic, military, clinical, and service delivery characteristics were poorly associated with reliable symptom worsening. One exception was receipt of a first PTSD EBP session in an inpatient setting, which was associated with a lower likelihood of experiencing reliable symptom worsening (MPOR = 0.73, 90 % CI = 0.66, 0.81; 2 % in ROPE). Reliable symptom worsening was an uncommon (but not rare) occurrence during PTSD EBPs and assessed correlates were poorly related to likelihood of experiencing reliable worsening. Further research is needed to understand the drivers of reliable symptom worsening and to compare rates observed in the current study to reliable symptom worsening that occurs naturally over time and that occurs during any PTSD treatment.

Augmentation of trauma-focused psychotherapy for post-traumatic stress disorder: a protocol for a systematic review and meta-analysis

INTRODUCTION

Despite the established status of trauma-focused psychotherapy (TFP) as a first-line treatment for post-traumatic stress disorder (PTSD), a substantial proportion of individuals do not achieve clinically significant improvement or discontinue treatment. Exploring augmentation strategies to enhance treatment outcomes is essential to reduce the overall burden PTSD puts on individuals and society. This protocol outlines a systematic review and meta-analysis of randomised controlled trials (RCTs) evaluating the efficacy of non-pharmacological augmentation strategies in addition to TFP for PTSD treatment.

METHODS AND ANALYSIS

We comprehensively searched PubMed, Embase, CENTRAL, PTSDpubs, PsycArticles, PsycINFO, PSYNDEX and CINAHL for RCTs without restrictions on publication dates or languages in October 2024. Study screening is currently ongoing. Additionally, we will perform forward and backward searches of the included studies and relevant reviews. Two reviewers will independently screen and select studies, extract data and assess the risk of bias. We will conduct a narrative review to qualitatively synthesise data and a meta-analysis to quantitatively compare the treatment efficacy of augmented TFP with TFP alone or TFP plus placebo. Primary outcomes will be both symptom severity and response rates. The secondary outcome will be dropout rates. We will explore sources of between-study heterogeneity and potential moderators through subgroup and meta-regression analyses. We will assess the overall quality of the included studies with the Grading of Recommendations Assessment, Development, and Evaluation system.

ETHICS AND DISSEMINATION

Ethical approval is not required. We intend to publish results in a peer-reviewed journal and provide materials and data through the Open Science Framework.

Memory processing by hippocampal adult-born neurons

This review provides an integrative overview of the functional roles of adult neurogenesis in the hippocampal dentate gyrus (DG), focusing specifically on its impact on memory processes across the lifespan. A distinguishing feature of this review is its systematic approach, organizing the contributions of adult-born neurons (ABNs) chronologically through the stages of memory-from initial encoding, through sleep-dependent consolidation, retrieval, and finally forgetting. Although the existence and extent of adult neurogenesis in the human DG remain debated, accumulating evidence suggests that ABNs support cognitive functions throughout adulthood. This perspective gains particular importance when considering cognitive decline associated with aging and neurological disorders such as Alzheimer's disease, which are linked to substantial reductions in adult neurogenesis. We compare traditional models of DG function with emerging evidence highlighting both shared and unique contributions of ABNs. For example, the DG is well-established for its role in pattern separation, and as key mediators of this function, ABNs-due to their transiently heightened plasticity and excitability-appear critical for discriminating novel or similar experiences. On the other hand, recent findings underscore the distinct and essential role of ABNs in memory consolidation during REM sleep, suggesting specialized functions of ABNs that are absent in developmentally born granule cells in the DG. Clinically, the potential therapeutic importance of enhancing neurogenesis in memory-related disorders, including post-traumatic stress disorder (PTSD), is emphasized, highlighting promising treatments such as memantine. Lastly, we outline key unresolved questions, advocating for future research aimed at understanding ABN-specific mechanisms. Far from being a mere evolutionary vestige, hippocampal ABNs represent dynamic and essential elements of neural plasticity that are critical for memory formation, adaptation, and resilience across the lifespan.

Transitioning into trauma-focused evidence-based psychotherapy for posttraumatic stress disorder from other treatments: a qualitative investigation

Although trauma-focused evidence-based psychotherapy (TF-EBP) is recommended for posttraumatic stress disorder (PTSD), rates of TF-EBP initiation among veterans is very low. Service delivery research has shown that other treatments are commonly provided to veterans diagnosed with PTSD, including stabilization treatments. As little is known about how veterans experience the transition to TF-EBP, we conducted a qualitative examination of veterans' perspectives on transitions in PTSD treatment. We recruited a diverse sample of veterans (n = 30) who recently initiated TF-EBP to complete semi-structured qualitative interviews focusing on six domains (PTSD treatment options, cultural sensitivity of treatment, PTSD treatment selection, transition criteria, beliefs about stabilization treatment, treatment needs/preferences). Rapid qualitative analysis procedures were used to identify themes. Themes included: (1) wanting to learn about TF-EBP earlier; (2) perceived risks of transition; (3) relationships with non-TF-EBP providers as transition barriers; (4) high symptoms and poor interpersonal functioning as transition facilitators; (5) benefits of treatment planning and handoffs; (6) prior therapy best when aligned with TF-EBP; (7) socialization as a key benefit of prior therapy; and (8) medications supporting TF-EBP. Results highlight the importance of introducing TF-EBP early to veterans, establishing and communicating a comprehensive care plan, and anchoring stabilization treatment in TF-EBP concepts.

Effectiveness of written exposure therapy for Korean patients with post-traumatic stress disorder: non-randomized treatment-as-usual waitlist-controlled study

Written exposure therapy (WET) is a five-session exposure-based protocol for treating post-traumatic stress disorder (PTSD). The brevity and tolerability of WET present the potential to overcome barriers in implementing evidence-based therapy for PTSD within the Korean mental healthcare system. This study investigated the effectiveness of WET in Korean patients with PTSD through a waitlist-controlled trial (KCT0008112). A total of 57 patients with PTSD were allocated non-randomly to either WET (n = 27) or treatment-as-usual waitlist groups (n = 30). Both groups were followed up until the twenty-fourth week after the initial session. Primary outcomes assessed included PTSD symptoms, depressive symptoms, and general function. In the WET group, significant improvements were observed in PTSD symptoms, depressive symptoms, and general function compared to the control group. After the waiting period, the waitlist group also participated in WET, and exhibited significant improvement in all scores. The between- and within-group effect sizes were large. The dropout rate in both groups was 10.9%, and the mean satisfaction ratings were 28.24 ± 3.33 (range 22-32; scale range 8-32). The present study provides evidence of WET successfully reducing PTSD and depressive symptoms and improving general function among Korean patients with PTSD. Moreover, WET was well tolerated and received by Korean patients with PTSD.

Short- and Long-Term Effectiveness of Brief Intensive Trauma Treatment for Adolescents With Posttraumatic Stress Disorder and Their Caregivers: Protocol for a Multicenter Randomized Controlled Trial

BACKGROUND

Childhood trauma is pervasive, with approximately 50% of adolescents experiencing at least one potentially traumatic event before adulthood. Eight percent to 33% of potentially traumatic event-exposed adolescents develop posttraumatic stress disorder (PTSD), which can cause extreme suffering and coincides with numerous comorbid illnesses and high-risk behaviors. PTSD can be effectively treated in adolescents through weekly sessions of eye movement desensitization and reprocessing or trauma-focused cognitive behavioral therapy. Despite the availability of these treatments, numerous severely traumatized adolescents do not receive available treatment options due to high treatment avoidance. In adolescents who receive care, a large group of youth does not experience a sufficient symptom decrease after regular treatment. In addition, dropout rates during prolonged treatment are substantial, varying between 10% and 30%. This underscores the need for innovative and brief trauma treatment. Pilot studies indicate that Brief Intensive Trauma Treatment (BITT) can be a safe and effective treatment for adolescents with PTSD. However, randomized controlled trials on its effectiveness are crucial and urgently needed.

OBJECTIVE

This is the first study to test the effectiveness of a 1-week BITT in adolescents with PTSD and comorbid symptoms and their caregivers.

METHODS

This multicenter, single-blinded randomized controlled trial will be conducted in 4 youth care centers in the European and Caribbean Netherlands: Levvel, Karakter, Fornhese-GGz Centraal, and Mental Health Caribbean (Bonaire). We will randomize adolescents (12-18 years old) with PTSD to a BITT (n=50) or waitlist control group (WLCG; n=50). BITT comprises 1-week (ie, 5 consecutive workdays) intensive trauma treatment, encompassing daily 90-minute manualized sessions of trauma-focused cognitive behavioral therapy and eye movement desensitization and reprocessing. The day begins and ends with psychomotor therapy. Caregivers receive daily parental counseling sessions consisting of psychoeducation and social support skill training. We will conduct measurements at similar intervals for both groups: at baseline; directly after BITT or WLCG; and at 3, 6, and 9 months' follow-up. The WLCG will receive BITT after the 3-month follow-up assessment. We will assess all study parameters using digital or face-to-face questionnaires and semistructured interviews. We will assess the primary outcome PTSD symptoms using the Child and Adolescent Trauma Screen 2 (CATS-2) and the Clinician-Administered PTSD Scale for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition])-Child/Adolescent Version (CAPS-CA-5).

RESULTS

As of September 2022, we enrolled 104 participants. Data will be collected until December 2025. Results are expected to be published in the summer of 2026.

CONCLUSIONS

This first, innovative study on BITT's effectiveness may enhance treatment outcomes for PTSD by preventing dropout, reducing avoidance, shortening therapy duration, and empowering therapists by working together intensively. This research will provide valuable insights across cultures for treating severely traumatized adolescents who do not benefit sufficiently from regular treatment.

Towards an understanding of readiness for trauma-focussed therapy in post-traumatic stress disorder: A conceptual integration of empirical data and theoretical constructs

For people with post-traumatic stress disorder (PTSD), the concept of being 'ready' for trauma-focused therapy (TFT) has emerged from research as an important factor in initiation and completion of therapy. Lack of readiness of individual service users has been proposed as a reason for poor uptake of TFT in large implementation programs. However, there has been almost no investigation of what constitutes readiness for TFT. In this review we build a conceptual case for readiness for TFT. We use qualitative research exploring PTSD treatment service users' and providers' experiences and perspectives of care together with two motivational theories (self-determination theory and motivation to engage in treatment) to propose a model of readiness for TFT. Readiness appears to encompass a) a motivational factor that includes willingness to undertake TFT and b) a set of determinants of motivation that may include the emotional burden of TFT, perceived suitability of TFT rationale; outcome expectancy; level of suffering; perceived competence; therapeutic relationship; autonomy; social supports; stigma; and problem recognition. This review is designed to encourage further research into this important clinical construct. It offers a new perspective on the need for a preparation phase before exposure in TFT, an issue of debate in the field.

Pharmacological treatments for co-occurring PTSD and substance use disorders: A systematic review

INTRODUCTION

Post-traumatic stress disorder and substance use disorders commonly co-occur and are associated with worse health outcomes. Currently, only psychosocial therapies are specifically recommended for use in the co-occurring population, but these come with numerous barriers to access and engagement. This study aims to identify potential pharmacological treatments to enhance treatment options and outcomes for this population.

METHODS

This systematic review identified studies on pharmacological treatment of co-occurring PTSD and SUD in humans, using validated outcome measurements, with study design of RCT, observational study, case control study or cohort study.

RESULTS

29 studies were identified for inclusion, looking at a range of 16 pharmacotherapies. A majority concentrated on alcohol use disorders and males, with many focused on the veteran population.

CONCLUSIONS

This is an area for further research, inclusive of more SUDs, genders and civilians. Future studies utilizing consistent dosing, populations and measurement outcomes will allow for future meta-analysis.

Residual symptoms following trauma-focused treatment for comorbid posttraumatic stress disorder and major depressive disorder

Despite effective psychotherapy options for posttraumatic stress disorder (PTSD), some patients do not fully respond, and even among those reporting substantial improvement, residual symptoms following treatment are common. Psychiatric conditions frequently co-occur with PTSD, yet research on residual symptoms among comorbid samples is lacking. This study examined residual symptoms of PTSD and depression among 71 active duty service members with PTSD and comorbid major depressive disorder (MDD). As part of a clinical trial, participants were randomized to cognitive processing therapy (CPT) or a novel treatment designed to address PTSD and comorbid MDD, behavioral activation-enhanced CPT (BA + CPT). Analyses compared individual residual symptoms between treatments and groups based on PTSD and MDD diagnostic status at posttreatment. For both PTSD and MDD, the conditional probabilities for each residual symptom did not differ between CPT and BA + CPT, suggesting treatment type did not influence which symptoms persisted. For the 36 service members who lost their PTSD diagnosis at posttreatment, conditional probabilities of residual PTSD symptoms were highest for sleep problems, concentration difficulties, and hypervigilance; for MDD symptoms, conditional probabilities were highest for sleep problems, concentration difficulties, and low energy. These most common residual symptoms were identical for the 31 service members who lost their MDD diagnosis at posttreatment. Residual symptoms observed among service members with PTSD and comorbid MDD mirrored those commonly identified among single disorder PTSD or MDD samples. Identifying and addressing residual symptoms most meaningful to patients will maximize benefit from PTSD treatment.

Effect of agreement between clinician-rated and patient-reported PTSD symptoms on intensive outpatient treatment outcomes

The level of agreement between self-reported posttraumatic stress disorder (PTSD) symptom severity, measured with the PTSD Checklist for DSM-5 (PCL-5), and severity measured via a clinician-rated measure, the Clinician Administered PTSD Scale for DSM-5 (CAPS-5), was tested as a predictor of the degree of improvement following a 2-week Intensive Outpatient Treatment Program (IOP). Differences in PTSD severity scores (PCL-5 minus CAPS-5) of US Veterans and service members with PTSD (N = 483) at Intake were used to categorize patients into 3 agreement groups: Congruent reporters, Limited Over-reporters and Extensive Over-reporters. A linear mixed model tested whether agreement group impacted the degree of improvement, measured as reduction in PCL-5 score, from IOP baseline to completion. The mean difference between the PCL-5 and CAPS-5 scores was 17.5 ± 13.1 points. Mean modeled reduction in PCL-5 scores from IOP Baseline to IOP Completion for Limited Over-reporters was -21.3 points (95 %CI -23.6, -19.1), which was significantly less than the reduction for Extensive Over-reporters (-27.6, 95 %CI -32.1, -23.1, p<.001), but not significantly different from Congruent reporters (-18.0, 95 %CI -22.7, -13.3, p=.17). Patients who most over-report their PTSD symptoms compared to trained clinicians show steepest declines in PTSD symptom severity with treatment. Personalizing treatment for PTSD may benefit from understanding the mechanisms contributing to these differences.

Evaluating Evidence-Based Psychotherapy Utilization Patterns Among Suicide-Risk-Stratified Veterans Diagnosed With Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is a prevalent psychiatric condition, particularly among US Veterans. PTSD-diagnosed patients are more likely to experience suicidal ideation, suicide attempts and death by suicide when compared to non-PTSD-diagnosed patients. The US Department of Veterans Affairs (VA) emphasizes evidence-based psychotherapy (EBP) for PTSD, including prolonged exposure and cognitive processing therapy. This study focuses on how suicide risk impacts PTSD by evaluating utilization of nondifferentiated psychotherapy and EBP in a national sample of VA patients diagnosed with PTSD who died by suicide in 2017-2018. The study used a dataset of VA patients diagnosed with PTSD who died by suicide and received psychotherapy in the year before death (cases) and patients who had comparable diagnoses, demographics and received psychotherapy during the same interval and remained alive (controls). Cases and controls were matched on suicide risk (high, moderate and low). The study tracked nondifferentiated psychotherapy and EBP and analyzed cases and control utilization rates across risk-tiers. The final sample included high-risk (cases = 171; controls = 2052), moderate-risk (cases = 428; controls = 4280) and low-risk (cases = 53; controls = 529) patients. EBP utilization was markedly low, especially among cases. Higher proportions of moderate- and low-risk controls received EBP and received more sessions than matched cases. Even with VA efforts to promote EBPs, usage remains limited, particularly among patients who die by suicide. Further research is needed to understand utilization barriers and improve EBP delivery to better support PTSD-diagnosed patients and reduce their suicide risk.

Mediators of change in a condensed online exposure-based intervention provided soon after trauma: insights from a randomised controlled trial

Background: The active mechanisms of change are unclear in early-provided exposure-based interventions for psychological trauma. This study aimed to address this gap by analysing weekly data from a randomised trial involving a 3-week therapist-guided online intervention based on prolonged exposure compared to a waiting-list control group.Method: The objective was to investigate whether changes in each of the four subscales of the Posttraumatic Stress Disorder Checklist, fifth version (PCL-5; i.e. intrusions, avoidance behaviours, negative alternations in cognitions and hyperarousal) during the three-week intervention period mediated subsequent improvements in other post-traumatic stress symptoms at the controlled 1-month follow-up. We included baseline levels of both the mediator and the outcome as well as changes in the outcome from baseline to week 3 as covariates in a mediation model.Results: The results showed that reductions in avoidance during the intervention period mediated reduced symptom levels of intrusions, negative alternations in cognitions, and hyperarousal at week 7 (z-scores of indirect effect estimates = -0.12 to -0.07). No other PCL-5 subscales were found to be mediators of change.Conclusions: The results from this study highlight the importance of addressing avoidance behaviours in online exposure-based interventions provided in the early aftermath of trauma. Sensitivity analysis showed that the mediation effects were sensitive to assumptions related to mediator-outcome confounders, which could be considered a study limitation.Trial registration: ClinicalTrials.gov identifier: NCT03850639.

Novel Pharmacologic and Other Somatic Treatment Approaches for Posttraumatic Stress Disorder in Adults: State of the Evidence

Posttraumatic stress disorder (PTSD) is a highly prevalent psychiatric disorder that can become chronic and debilitating when left untreated. The most commonly recommended first-line treatments for PTSD among adults are individual trauma-focused psychotherapies. Other evidence-based treatments include specific antidepressant medications and non-trauma-focused psychotherapies. Despite the effectiveness of these available treatments, many patients' symptoms do not remit. This has led to the search for novel treatments for PTSD. In this review, the authors critically evaluate the data supporting several emerging pharmacological and other somatic interventions in the categories of medication-assisted psychotherapy, novel medication monotherapy strategies, and neuromodulation, selected because of the salience of their mechanisms of action to the pathophysiology of PTSD (e.g., MDMA-assisted psychotherapy, ketamine, cannabidiol, transcranial magnetic stimulation). The authors also evaluate the evidence for treatments that are the focus of increasing scientific or public interest (i.e., hyperbaric oxygen therapy, stellate ganglion block, neurofeedback). To date, the evidence supporting most novel pharmacological and somatic treatments for PTSD is preliminary and highly variable; however, the data for several specific treatments, such as transcranial magnetic stimulation, are encouraging.

Predictors of study dropout in cognitive-behavioural therapy with a trauma focus for post-traumatic stress disorder in adults: An individual participant data meta-analysis

BACKGROUND

Available empirical evidence on participant-level factors associated with dropout from psychotherapies for post-traumatic stress disorder (PTSD) is both limited and inconclusive. More comprehensive understanding of the various factors that contribute to study dropout from cognitive-behavioural therapy with a trauma focus (CBT-TF) is crucial for enhancing treatment outcomes.

OBJECTIVE

Using an individual participant data meta-analysis (IPD-MA) design, we examined participant-level predictors of study dropout from CBT-TF interventions for PTSD.

METHODS

A comprehensive systematic literature search was undertaken to identify randomised controlled trials comparing CBT-TF with waitlist control, treatment-as-usual or another therapy. Academic databases were screened from conception until 11 January 2021. Eligible interventions were required to be individual and in-person delivered. Participants were considered dropouts if they did not complete the post-treatment assessment.

FINDINGS

The systematic literature search identified 81 eligible studies (n=3330). Data were pooled from 25 available CBT-TF studies comprising 823 participants. Overall, 221 (27%) of the 823 dropped out. Of 581 civilians, 133 (23%) dropped out, as did 75 (42%) of 178 military personnel/veterans. Bivariate and multivariate analyses indicated that military personnel/veterans (RR 2.37) had a significantly greater risk of dropout than civilians. Furthermore, the chance of dropping out significantly decreased with advancing age (continuous; RR 0.98).

CONCLUSIONS

These findings underscore the risk of premature termination from CBT-TF among younger adults and military veterans/personnel.

CLINICAL IMPLICATION

Understanding predictors can inform the development of retention strategies tailored to at-risk subgroups, enhance engagement, improve adherence and yield better treatment outcomes.

Walking the line between fidelity and flexibility: A conceptual review of personalized approaches to manualized treatments for posttraumatic stress disorder

The heterogeneity of the core symptoms of posttraumatic stress disorder (PTSD), high rates of comorbid mental and physical health conditions, and substantial impact of the disorder on functioning and well-being contribute to complex clinical presentations that can be challenging to treat. Despite these challenges, there are excellent manualized treatments for PTSD with significant empirical support. Although the success of frontline treatments for PTSD is evident, there remains room for improvement as indicated by suboptimal response and attrition rates. To address challenges to optimal therapy outcomes (COTOs), researchers have conducted numerous clinical trials designed to (a) enhance the core structure of treatment protocols to increase flexibility or (b) expand the protocols to address comorbid conditions that inhibit recovery. However, it is implausible to ever conduct the number of enhancement and expansion clinical trials necessary to test manual modifications for the universe of possible COTOs. This conceptual review describes the concept of a personalized model of therapy that leverages a case formulation approach to implementing an evidence-based treatment for PTSD. This personalized approach provides guidance for the clinician in assessing the patient's COTOs, monitoring them throughout treatment, and relying on the patient's idiosyncratic data to inform treatment decisions, including how and when to diverge from treatment when clinically indicated and ensuring a clear path to return to trauma-focused work when the COTO is stabilized. This personalized, case formulation approach to treating PTSD provides guidance for adopting a more flexible approach to treating clinically complex patients while ensuring fidelity to the protocol.

A systematic review and meta-analysis of PTSD symptoms at mid-treatment during trauma-focused treatment for PTSD

There is concern that trauma memory processing in psychological therapies leads to PTSD symptom exacerbation. We compared PTSD symptoms at mid-treatment in trauma-focused psychological therapy to control groups. We systematically searched multiple databases and searched grey literature. We included randomised controlled trials involving adults comparing trauma-focused psychological interventions with active non-trauma-focused interventions or waitlist conditions. Twenty-three studies met our inclusion criteria. We found no evidence of PTSD symptom exacerbation at mid-treatment in trauma-focused interventions compared to control groups (g=-.16, [95 % confidence interval, CI, -.34,.03]). Sensitivity analyses with high quality studies (risk of bias assessment ≥ 7; g=-.25; [95 % CI -.48, -.03], k = 12) and studies with passive controls (g=-.32; [95 % CI -.59, -.05], k = 8) yielded small effect sizes favouring trauma-focused interventions. At post-treatment, trauma-focused interventions yielded a medium effect on PTSD symptoms compared to all controls (g=-.57; [CI -.79, -.35], k = 23). Regarding depression, trauma-focused interventions yielded a small effect size compared to controls at mid-treatment (g=-.23; [95 % CI -.39, -.08], k = 12) and post-treatment (g=-.45; [CI -.66, -.25], k = 12). This meta-analysis found no evidence that trauma-focused psychotherapies elicit symptom exacerbation at mid-treatment in terms of PTSD or depression symptoms. Instead, this meta-analysis suggests that the benefits of trauma-focused interventions can be experienced through improved depression and possibly PTSD before the conclusion of therapy. However, it is possible that symptom exacerbation occurred before mid-treatment and/or that people who experience symptom exacerbation drop out of studies and so are not included in the analysis.

Secondary traumatization in refugee care-EMDR intervention for interpreters (STEIN): a study protocol for a quasi-randomized controlled trial

BACKGROUND

By the end of 2022, more than 100 million people worldwide fled their homes. Before, during and after their flight, refugees have high risk of experiencing traumatic events. Accordingly, around every third refugee is affected by posttraumatic stress disorder. For adequate mental health care, the service of interpreters is often urgently needed to overcome existing language barriers. However, repeated exposure with details of traumatic narratives, as experienced by interpreters, can be burdensome and can lead to trauma sequela symptoms in terms of secondary traumatic stress. Only few studies have examined the treatment of secondary traumatic stress to date. Based on the recommendations for the treatment of posttraumatic stress disorder with confrontational methods, this study was designed to evaluate the effectiveness of an eye movement desensitization and reprocessing (EMDR) intervention in a sample of interpreters working in refugee care suffering from secondary traumatic stress symptoms.

METHODS

To evaluate the effectiveness of an EMDR intervention for the treatment of secondary traumatic stress symptoms, a quasi-randomized controlled trial using a waiting group design will be performed. Participants will be treated with a maximum of 6 sessions based on EMDR standard protocol. Primary outcome is the symptom load of secondary traumatic stress, assessed with the Questionnaire for Secondary Traumatization, while secondary outcomes comprise further symptom complexes such as PTSD due to self-experienced traumatic events, depression, anxiety, and somatization as well as quality of life, quality of professional life, and psychological wellbeing that will be assessed with the PDS, PHQ-9, GAD-7, SSD-12, SF-12, PROQOL-5, and WHO-5, respectively.

DISCUSSION

Our primary interest is to determine the efficacy of an EMDR intervention in interpreters affected by secondary traumatic stress, especially how many sessions are needed for significant symptom reduction. Change of associated symptom complexes and quality of life will be investigated. Reprocessing one's own stressful experiences may also contribute to this, which is not the focus of the treatment but relevant to the EMDR protocol. This study aims to assess if EMDR could be an acceptable, effective, and time-efficient method for reducing work-related secondary traumatization.

Efficacy of an internet-based guided trauma-focused intervention in reducing ICD-11 posttraumatic stress disorder symptoms: study protocol of a randomized controlled trial

BACKGROUND

Posttraumatic stress disorder (PTSD) is a common mental disorder. However, many cases of PTSD remain untreated because of limited healthcare resources and other treatment-seeking barriers. Effective internet-based interventions could help to improve access to PTSD treatments. Therefore, the main objective of the planned randomized controlled trial is to evaluate the efficacy of the Lithuanian version of the guided internet-based self-help programme (Spring) in reducing ICD-11 PTSD symptoms.

METHODS

The planned sample size is 50 participants exposed to different traumatic experiences. Participants eligible for the study will be randomized into two study groups: the immediate treatment group and the delayed treatment control group. Both groups will receive guided trauma-focused ICBT intervention, but the delayed treatment group will receive access to the programme five months after randomization. The International Trauma Interview (ITI) will be used for the assessment of ICD-11 PTSD symptoms at pre-treatment, post-treatment, and at a 3-month follow-up. Changes in disturbances in self-organization, depression and anxiety levels, as well as posttraumatic cognitions and trauma-related shame, will also be evaluated. In addition, associations between changes in symptoms of PTSD and readiness for treatment, treatment expectations and working alliance will be explored. Changes in treatment outcomes will be evaluated using multiple Latent Change Models.

DISCUSSION

This study is expected to contribute to valuable knowledge on the efficacy of internet-based interventions for posttraumatic stress disorder.

A guided single session intervention to reduce intrusive memories of work-related trauma: a randomised controlled trial with healthcare workers in the COVID-19 pandemic

BACKGROUND

Intrusive memories of psychologically traumatic events bring distress both sub-clinically and clinically. This parallel-group, two-arm randomised controlled trial evaluated the effect of a brief behavioural intervention on reducing intrusive memories in frontline healthcare workers exposed to traumatic events during the COVID-19 pandemic.

METHODS

Participants with at least two intrusive memories of work-related trauma in the week before recruitment were randomised 1:1 to an imagery-competing task intervention (n = 73) or attention-based control task (n = 71). The number of intrusive memories was assessed at baseline and 5 weeks after the guided session (primary endpoint).

RESULTS

The intervention significantly reduced intrusive memory frequency compared with control [intervention Mdn = 1.0 (IQR = 0-3), control Mdn = 5.0 (IQR = 1-17); p < 0.0001, IRR = 0.30; 95% CI = 0.17-0.53] and led to fewer post-traumatic stress-related symptoms at 1, 3 and 6 month follow-ups (secondary endpoints). Participants and statisticians were blinded to allocation. Adverse events data were acquired throughout the trial, demonstrating safety. There was high adherence and low attrition.

CONCLUSIONS

This brief, single-symptom, repeatable digital intervention for subclinical-to-clinical samples after trauma allows scalability, taking a preventing-to-treating approach after trauma.

Clinicians' perspectives on retraumatisation during trauma-focused interventions for post-traumatic stress disorder: A survey of UK mental health professionals

Concerns regarding retraumatisation have been identified as a barrier to delivering trauma-focused therapy for post-traumatic stress disorder (PTSD). We explored clinicians' understanding of what constitutes potential signs of retraumatisation (PSoR), reported incidences of witnessing retraumatisation, use of (and confidence in) therapies for PTSD, fear of retraumatisation during therapy for PTSD, and whether having witnessed retraumatisation was associated with these variables. We surveyed 348 clinicians. There was variation in what clinicians viewed as PSoR. Retraumatisation was reported by clinicians in 3.4 % of patients undergoing trauma-focused therapy for PTSD. A variety of trauma-focused and non-trauma-focused therapies were routinely used, yet 14.4 % reported not using trauma-focused therapy. There was a significant negative correlation between participants' highest reported confidence in trauma-focused therapy and endorsement of PSoR (r = -.25) and fear of retraumatisation (r = -.28). Mean fear of retraumatisation was 30.3 (SD=23.4; a score we derived from asking participants out of 100 how much they worry about trauma-focused therapy being harmful in its own right/leading to a worsening of PTSD symptoms). Participants who had witnessed retraumatisation reported significantly greater endorsement of PSoR (d=.69 [95 % CI .37, 1.02]) and fear of retraumatisation (d=.94 [95 % CI .61, 1.26]). Confidence in using therapies for PTSD was varied and related to how clinicians understood retraumatisation. Retraumatisation is uncommon, but there is variability in clinicians' interpretation of what retraumatisation is, and its utility warrants research.

Impact of three variants of prolonged exposure therapy on comorbid diagnoses in patients with childhood abuse-related PTSD

Recent studies indicated that Prolonged Exposure (PE) is safe and effective for posttraumatic stress disorder (PTSD). It is unclear whether PE also leads to a reduction in comorbid diagnoses. Data from a large randomized controlled trial (N = 149) on the effects of three variants of PE for PTSD were used. We examined the treatment effects on co-morbid diagnoses of depressive, anxiety, obsessive compulsive, substance abuse, psychotic, eating and personality disorders in a sample of patients with PTSD related to childhood abuse. Outcomes were assessed with clinical interviews at baseline, post-treatment and at 6- and 12-month follow-up. All variants of PE led to a decrease from baseline to post-treatment in diagnoses of depressive, anxiety, substance use and personality disorders. Improvements were sustained during follow-up. We found an additional decrease in the number of patients that fulfilled the diagnostic criteria of a depressive disorder between 6- and 12-month follow-up. No significant changes were observed for the presence of OCD, psychotic and eating disorders. Findings suggest that it is effective to treat PTSD related to childhood abuse with trauma-focused treatments since our 14-to-16 weeks PE for PTSD resulted in reductions in comorbid diagnoses of depressive, anxiety, substance use and personality disorders.

Study protocol for a single-blind, parallel-group, randomized, controlled superiority trial of intensive versus weekly delivered prolonged exposure for adults with post-traumatic stress disorder

BACKGROUND

Prolonged exposure (PE) therapy is widely recognized as an effective treatment for post-traumatic stress disorder (PTSD) and is often considered one of the primary options for addressing this condition. Nevertheless, a significant proportion of patients (30-51%) fail to demonstrate clinically significant symptom changes. One of the reasons is that a high proportion of patients drop out from treatment, which often lasts for a minimum of 3-4 months. Hence, there is an urgent need for PTSD treatments that can be delivered to decrease dropout rates. A more intensive PE treatment approach has been suggested to decrease dropout rates and in addition achieve faster recovery rates and has shown promising effects on reducing PTSD symptoms but needs to be tested against firsthand treatment.

METHODS

This single-blind, randomized controlled trial (N = 140) will compare an intensive delivery format of prolonged exposure (iPE) against standard weekly delivered sessions of PE. The primary outcome is change on the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). Secondary outcomes include self-rated measures of symptoms of PTSD and complex PTSD, depression and quality of life, speed of recovery, cost effectiveness, dropout rates, and adverse events.

DISCUSSION

This study will be the first to compare iPE with first-line treatment in a psychiatric outpatient setting. One of the key strengths of this study lies in its implementation within a clinical setting and the broad eligibility criteria. Additionally, the utilization of gold-standard assessment measures ensures the accuracy and reliability of the outcomes. However, several potential challenges may arise during the study's execution. These challenges may include difficulties in participant recruitment, ensuring adequate participant retention, adherence to the treatment protocol, and maintaining therapist retention mostly due to recruitment taking place at one single clinic.

Development of a stepped care intervention model of evidence-based interventions for the management of posttraumatic stress in the Belgian Police

Background: Police officers are frequently exposed to a wide variety of potentially traumatic events (PTE) and are therefore at a considerable risk of developing posttraumatic stress disorder (PTSD). Previous research estimated the point prevalence of PTSD in Belgian police officers at 7.4%, significantly higher than in the general population. An effective organisational strategy to manage posttraumatic stress is essential.Objective: We aimed to develop a novel organisational approach regarding traumatic stress for Belgian police, combining evidence-based strategies for the prevention and treatment of posttraumatic stress in a stepped care intervention model.Method: In a broad development process, we combined scientific literature, case studies of best practices from other police organisations with insights gathered from a number of expert panels, thematic working groups and feedback groups.Results: A comprehensive stepped care intervention model was developed, consisting of evidence-based interventions for the prevention and treatment of posttraumatic stress.Conclusions: The intervention model is a promising organisational strategy for the management of posttraumatic stress in police organisations based on evidence-based interventions. Its effectiveness will be studied in the coming years.

EMDR v. other psychological therapies for PTSD: a systematic review and individual participant data meta-analysis

BACKGROUND

This systematic review and individual participant data meta-analysis (IPDMA) examined the overall effectiveness of eye movement desensitization and reprocessing (EMDR) in reducing posttraumatic stress disorder (PTSD) symptoms, achieving response and remission, and reducing treatment dropout among adults with PTSD compared to other psychological treatments. Additionally, we examined available participant-level moderators of the efficacy of EMDR.

METHODS

This study included randomized controlled trials. Eligible studies were identified by a systematic search in PubMed, Embase, PsyclNFO, PTSDpubs, and CENTRAL. The target population was adults with above-threshold baseline PTSD symptoms. Trials were eligible if at least 70% of study participants had been diagnosed with PTSD using a structured clinical interview. Primary outcomes included PTSD symptom severity, treatment response, and PTSD remission. Treatment dropout was a secondary outcome. The systematic search retrieved 15 eligible randomized controlled trials (RCTs); 8 of these 15 were able to be included in this IPDMA (346 patients). Comparator treatments included relaxation therapy, emotional freedom technique, trauma-focused cognitive behavioral psychotherapies, and REM-desensitization.

RESULTS

One-stage IPDMA found no significant difference between EMDR and other psychological treatments in reducing PTSD symptom severity (β = -0.24), achieving response (β = 0.86), attaining remission (β = 1.05), or reducing treatment dropout rates (β = -0.25). Moderator analyses found unemployed participants receiving EMDR had higher PTSD symptom severity at the post-test, and males were more likely to drop out of EMDR treatment than females.

CONCLUSION

The current study found no significant difference between EMDR and other psychological treatments. We found some indication of the moderating effects of gender and employment status.

Differential posttraumatic stress disorder symptom cluster response to stellate ganglion block: secondary analysis of a randomized controlled trial

Empirically supported treatments for posttraumatic stress disorder (PTSD) exist, but research suggests these therapies are less effective, acceptable, and feasible to deliver to active duty service members (SMs) compared to civilians. Stellate ganglion block (SGB) procedure, in which a local anesthetic is injected around the cervical sympathetic chain or stellate ganglion to temporarily inhibit sympathetic nervous activity, is gaining popularity as an alternative PTSD treatment in military settings. However, it is unknown whether certain PTSD symptoms are more responsive to SGB than others. The current study involved a secondary analysis of data collected from a previous randomized controlled trial of SGB compared to sham (normal saline) injection (N = 113 SMs). PTSD symptoms were assessed via clinical interview and self-report at baseline and 8 weeks post-SGB or sham. Logistic regression analyses showed that the marked alterations in arousal and reactivity PTSD symptom cluster demonstrated the greatest symptom severity reductions after SGB, relative to sham. The reexperiencing cluster also showed pronounced response to SGB in clinician-rated but not self-reported outcomes. Post-hoc item-level analyses suggested that arousal and reactivity cluster findings were driven by reductions in hypervigilance, concentration difficulties, and sleep disturbance, whereas clinician-rated reexperiencing cluster findings were driven by reductions in physiological reactions to trauma cues, emotional reactions to trauma cues, and intrusions. Our findings align with a burgeoning literature positioning SGB as a potential novel or adjunctive PTSD treatment. Results could guide future hypothesis-driven research on mediators of therapeutic change during SGB for PTSD symptoms in SMs.

A pilot randomised control study to investigate the effect of the South African Adolescence Group Sleep Intervention (SAASI) on adolescent sleep and PTSD

Background: Trauma exposure prevalence and consequent post-traumatic stress disorder among South African adolescents are significant. Sleep disturbances are among the most frequently reported difficulties faced by those dealing with PTSD. The current study examined the feasibility and preliminary efficacy of the South African Adolescence Group Sleep Intervention on PTSD symptom severity and sleep disturbance.Method: Sixty-one adolescents with PTSD diagnoses and sleep disturbance were randomly assigned (1:1) to one individual and four group sessions of a sleep intervention (SAASI) or a control group. Participants completed the Child PTSD symptom scale for DSM5 (CPSS-5) and the Pittsburgh Sleep Quality Index (PSQI) among other sleep and psychiatric measures. The trial was registered on the Pan African Trial Registry (PACTR202208559723690).Results: There was a significant but similar decrease in PSQI scores in both groups over time indicating no overall intervention effect (Wald test = -2.18, p = .029), mean slope = -0.2 (95% CI: -0.37 to -0.02) (p = .583). On the CPSS-5, interaction between groups was also not significant (p = .291). Despite this overall finding, the mean difference in CPSS-SR-5 scores increased over time, with the difference between groups post-treatment -9.10 (95%CI: -18.00 to -0.21), p = .045 and the 1-month follow-up contrast - 11.22 (95%CI: -22.43 to -0.03), p = .049 suggesting that PTSD symptom severity decreased more in the intervention group than the control group. The dropout rate was higher than expected for both the intervention (n = 10; 32%) and control (n = 8; 26.7%) groups. Dropout were mostly school commitments or travel related.Conclusions: Early findings suggest a trend towards dual improvement in sleep quality and PTSD symptom severity in adolescents with a sleep disturbance and PTSD receiving a group sleep intervention (SAASI). Further investigation in a properly powered RCT with detailed retention planning is indicated.

Multimodal exercise programs may improve posttraumatic stress disorders symptoms and quality of life in adults with PTSD: An overview of systematic reviews with meta-analysis

OBJECTIVE

This overview of reviews aimed to summarize the effectiveness of exercise, regular physical activity or mind-body exercises on posttraumatic stress disorder (PTSD) symptoms and comorbidities associated with PTSD (e.g. depression symptoms) among individuals without age, gender, race, ethnicity or setting restrictions.

DATA SOURCES

The CINAHL, Embase, PubMed and SPORTDiscus databases were searched from inception to November 16, 2023.

REVIEW METHODS

Systematic reviews with meta-analysis of randomized clinical trials evaluating exercise, regular physical activity or mind-body exercises were considered. Control groups and outcome measures were not restricted. AMSTAR 2 assessed the methodological quality of reviews. The overlap between reviews was calculated.

RESULTS

A total of 14 systematic reviews were included meta-analyzing 23 distinct randomized clinical trials. There was a very high overlap between reviews (corrected covered area = 16%). PTSD symptoms, depression symptoms, anxiety symptoms, sleep quality, substance abuse and quality of life were meta-analyzed. No reviews meta-analyzed the effects of regular physical activity. Overall, the meta-analyses found multicomponent exercise programs may have positive results in reducing PTSD symptoms and improving quality of life. In addition, the results of yoga were inconsistent across the meta-analyses for PTSD symptoms, and no differences between groups were found in favor of yoga for depression symptoms. Finally, no specific conclusions could be made about anxiety symptoms, sleep quality and substance abuse.

CONCLUSION

A multicomponent exercise program may be effective in improving PTSD symptoms and quality of life, whereas yoga may be ineffective for depression symptoms in adults with PTSD.

Efficacy and acceptability of music therapy for post-traumatic stress disorder: a systematic review and meta-analysis of randomized controlled trials

Background: Music therapy is increasingly examined in randomized controlled trials (RCTs) and shows potential in treating post-traumatic stress disorder (PTSD).Objective: This systematic review and meta-analysis critically evaluates the current clinical evidence supporting the efficacy and acceptability of music therapy for PTSD.Method: RCTs comparing music therapy in addition to care as usual (CAU) versus either CAU alone or CAU combined with standard psychotherapy/pharmacotherapy for PTSD were retrieved from major English - and Chinese-language databases. Standardized mean differences (SMDs) for post-treatment PTSD symptom scores and risk differences (RDs) for retention rates upon treatment completion were calculated to assess the efficacy and acceptability of music therapy, respectively. The Cochrane risk of bias (RoB) tool 2.0 and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) were used to assess the RoB of included studies and certainty of the evidence, respectively.Results: Nine studies, incorporating 527 PTSD patients, were included, all with high RoB. The post-treatment PTSD symptom scores were significantly lower in the music therapy group than the inactive control group (SMD = -1.64, P < .001), but comparable between the music therapy group and the active control group (SMD = -0.28, P = .330). The retention rates did not differ significantly between the music therapy group and both control groups (RD = 0.03, P = .769; RD = 0.16, P = .829). The GRADE rated certainty level of evidence as low.Conclusions: Although meta-analytic findings suggest that music therapy is effective in reducing post-traumatic symptoms in individuals with PTSD, with its therapeutic effect comparable to that of standard psychotherapy, the low level of certainty limits its generalizability. More methodologically stringent studies are warranted to strengthen the clinical evidence for the efficacy and acceptability of music therapy for PTSD.

Clinician Burnout and Effectiveness of Guideline-Recommended Psychotherapies

Importance

Clinician burnout has been associated with clinician outcomes, but the association with patient outcomes remains unclear.

Objective

To evaluate the association between clinician burnout and the outcomes of patients receiving of guideline-recommended trauma-focused psychotherapies for posttraumatic stress disorder (PTSD).

Design, Setting, and Participants

This cohort study was set at the US Veterans Affairs Health Care System and included licensed therapists who provided trauma-focused psychotherapies and responded to an online survey between May 2 and October 8, 2019, and their patients who initiated a trauma-focused therapy during the following year. Patient data were collected through December 31, 2020. Data were analyzed from May to September 2023.

Exposures

Therapists completing the survey reported burnout with a 5-point validated measure taken from the Physician Worklife Study. Burnout was defined as scores of 3 or more.

Main Outcomes and Measures

The primary outcome was patients' clinically meaningful improvement in PTSD symptoms according to the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). Patient dropout, therapist adherence, and session spacing was assessed through electronic health records. Multivariable random-effects logistic regression examined the association of therapist burnout and clinically meaningful improvement, adjusted for case-mix.

Results

In this study, 165 of 180 (91.7%) therapists (89 [53.9%] female) completed the burnout measure and provided trauma-focused psychotherapies to 1268 patients (961 [75.8%] male) with outcome data. Fifty-eight (35.2%) therapists endorsed burnout. One third of patients (431 [34.0%]) met criterion for clinically meaningful improvement. Clinically meaningful improvement in PTSD symptoms was experienced by 120 (28.3%) of the 424 patients seen by therapists who reported burnout and 311 (36.8%) of the 844 patients seen by therapists without burnout. Burnout was associated with lower odds of clinically meaningful improvement (adjusted odds ratio [OR],0.63; 95% CI, 0.48-0.85). The odds of clinically meaningful improvement were reduced for patients who dropped out (OR, 0.15; 95% CI, 0.11-0.20) and had greater session spacing (OR, 0.80; 95% CI, 0.70-0.92). Therapist adherence was not associated with therapy effectiveness. Adjusting for dropout or session spacing did not meaningfully alter the magnitude of the association between burnout and clinically meaningful improvement.

Conclusions and Relevance

In this prospective cohort study, therapist burnout was associated with reduced effectiveness of trauma-focused psychotherapies. Studying when and how burnout affects patient outcomes may inform workplace interventions.

Exploring the feasibility and acceptance of huddinge online prolonged exposure therapy (HOPE) for severe and complex PTSD

Background: Trauma-focused cognitive behavioural therapy such as prolonged exposure is considered firsthand choice for treatment of posttraumatic stress disorder (PTSD) but is seldom available in regular care. Digital therapy is proposed to bridge this gap, but its effectiveness for severe and complex PTSD is uncertain. The primary objective of the current study was to examine the feasibility, acceptability, and preliminary effects of digital therapist-guided prolonged exposure (Huddinge Online Prolonged Exposure; HOPE).Method: Thirty participants with moderate to severe PTSD, with the majority self-reporting complex PTSD symptoms, received HOPE over a ten-week period. Eighty percent of participants had been diagnosed with other psychiatric comorbidity by a mental health professional. Primary outcome was the feasibility and acceptability of treatment. Participants were repeatedly assessed using clinician- and self-rated outcome measures at baseline, during the treatment period, post-treatment, and at 1-month and 6-month follow-ups to estimate preliminary treatment effects. The Clinician Administered PTSD Scale version 5 (CAPS-5), administered by independent assessors, evaluated PTSD symptom severity.Results: HOPE proved feasible and effective, delivering evidence-based treatment content in a psychiatric outpatient setting with reduced therapist time. The treatment was well-tolerated, with no severe adverse events and a 17% dropout rate. Sixty-four percent completed the exposure-based portion of the treatment, and overall satisfaction measured by the Client Satisfaction Questionnaire was moderate. Furthermore, significant reductions in PTSD symptoms as assessed with the CAPS-5 (Cohen's d = 1.30 [95% CI -1.79 to -0.82]) at the primary endpoint 1 month which were sustained at the 6-month follow up.Conclusion: Altogether, this study indicate feasibility of treating severe and complex PTSD through a digital PE intervention, thereby building upon and extending previous research findings. Large-scale controlled trials are needed to further validate the specific effect and long-term benefits of HOPE.Trial registration: ClinicalTrials.gov identifier: NCT05560854.

Cannabis use and trauma-focused treatment for co-occurring posttraumatic stress disorder and substance use disorders: A meta-analysis of individual patient data

High rates of cannabis use among people with posttraumatic stress disorder (PTSD) have raised questions about the efficacy of evidence-based PTSD treatments for individuals reporting cannabis use, particularly those with co-occurring alcohol or other substance use disorders (SUDs). Using a subset of four randomized clinical trials (RCTs) included in Project Harmony, an individual patient meta-analysis of 36 RCTs (total N = 4046) of treatments for co-occurring PTSD+SUD, we examined differences in trauma-focused (TF) and non-trauma-focused (non-TF) treatment outcomes for individuals who did and did not endorse baseline cannabis use (N = 410; 70% male; 33.2% endorsed cannabis use). Propensity score-weighted mixed effects modeling evaluated main and interactive effects of treatment assignment (TF versus non-TF) and baseline cannabis use (yes/no) on attendance rates and within-treatment changes in PTSD, alcohol, and non-cannabis drug use severity. Results revealed significant improvements across outcomes among participants in all conditions, with larger PTSD symptom reductions but lower attendance among individuals receiving TF versus non-TF treatment in both cannabis groups. Participants achieved similar reductions in alcohol and drug use across all conditions. TF outperformed non-TF treatments regardless of recent cannabis use, underscoring the importance of reducing barriers to accessing TF treatments for individuals reporting cannabis use.

The Management of Posttraumatic Stress Disorder and Acute Stress Disorder: Synopsis of the 2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline

DESCRIPTION

The U.S. Department of Veterans Affairs (VA) and Department of Defense (DoD) worked together to revise the 2017 VA/DoD Clinical Practice Guideline for the Management of Posttraumatic Stress Disorder and Acute Stress Disorder. This article summarizes the 2023 clinical practice guideline (CPG) and its development process, focusing on assessments and treatments for which evidence was sufficient to support a recommendation for or against.

METHODS

Subject experts from both departments developed 12 key questions and reviewed the published literature after a systematic search using the PICOTS (population, intervention, comparator, outcomes, timing of outcomes measurement, and setting) method. The evidence was then evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method. Recommendations were made after consensus was reached; they were based on quality and strength of evidence and informed by other factors, including feasibility and patient perspectives. Once the draft was peer reviewed by an external group of experts and their inputs were incorporated, the final document was completed.

RECOMMENDATIONS

The revised CPG includes 34 recommendations in the following 5 topic areas: assessment and diagnosis, prevention, treatment, treatment of nightmares, and treatment of posttraumatic stress disorder (PTSD) with co-occurring conditions. Six recommendations on PTSD treatment were rated as strong. The CPG recommends use of specific manualized psychotherapies over pharmacotherapy; prolonged exposure, cognitive processing therapy, or eye movement desensitization and reprocessing psychotherapy; paroxetine, sertraline, or venlafaxine; and secure video teleconferencing to deliver recommended psychotherapy when that therapy has been validated for use with video teleconferencing or when other options are unavailable. The CPG also recommends against use of benzodiazepines, cannabis, or cannabis-derived products. Providers are encouraged to use this guideline to support evidence-based, patient-centered care and shared decision making to optimize individuals' health outcomes and quality of life.

Evaluation of implementation facilitation integrated into a national mentoring programme to improve access to evidence-based psychotherapy for post-traumatic stress disorder within the veterans health administration: a quality improvement report

Despite the resources dedicated to specialised mental healthcare for patients with post-traumatic stress disorder (PTSD) within the US Veterans Health Administration, evidence-based psychotherapies (EBPs) for PTSD have been underutilised, as evidenced by low EBP reach to patients. A research-operation collaboration evaluated whether implementation facilitation delivered by regional PTSD mentors as part of a national mentoring programme improved EBP reach compared with less-intensive quality improvement interventions. We used a non-equivalent comparison-group design that included all PTSD clinics with low EBP reach at baseline (n=51). Clinics were grouped into one of four quality improvement conditions according to self-selection by regional PTSD mentors: facilitation (n=6), learning collaborative (n=15), mentoring as usual in the regions that had facilitation-target clinics (n=15) and mentoring as usual in other regions (n=15). The primary outcome was EBP reach among therapy patients with PTSD at preintervention baseline and postintervention sustainment periods. We used the ratio of odds ratios (ROR) between the two time periods to evaluate the effectiveness of facilitation compared with the other conditions, adjusting for patient-level and clinic-level confounders. 26 126 veterans with PTSD received psychotherapy in one of 51 low-reach PTSD clinics during preintervention baseline and postintervention sustainment periods. The odds of a patient receiving an EBP increased over time across conditions. The adjusted ORs of a patient receiving an EBP from baseline to sustainment were 1.35-1.69 times larger in clinics that received facilitation compared with the three comparison conditions (adjusted RORs of comparison condition versus facilitation ranged from 0.59 (95% CI 0.47 to 0.75) to 0.74 (95% CI 0.58 to 0.94)). Implementation facilitation can be integrated into a national programme for quality improvement for PTSD specialty care and may be particularly useful when less-intensive approaches are not sufficiently effective.

Why Chaplaincy at Asylum Centers is a Good Idea: A Care Ethics Perspective on Spiritual Care for Refugees

This article argues in favor of introducing chaplaincy care at asylum centers and develops three arguments for doing so. First, chaplaincy is one way to protect the right to health of refugees and to improve their spiritual well-being. The positive contribution of chaplaincy services to mental health care is increasingly recognized, especially in the domain of PTSD. Second, chaplaincy services support asylum seekers in exercising their freedom of religion while entrusted to state care. Chaplains can create a safe space for asylum seekers to reflect on their spiritual and religious needs, orientation and belonging. Third, chaplains are well positioned to help asylum seekers in rebuilding their life-sustaining web, while at the same time promoting a climate of inclusion and respect in and outside the asylum center.

Acupuncture Therapy for Military Veterans Suffering from Posttraumatic Stress Disorder and Related Symptoms: A Scoping Review of Clinical Studies

Military personnel in combat face a high risk of developing posttraumatic stress disorder (PTSD). In this study, a protocol-based scoping review was conducted to identify the current status of research on the efficacy of acupuncture for treating combat-related PTSD in military personnel. A literature search was conducted across 14 databases in November 2022, and data from the included studies were collected and descriptively analyzed. A total of eight studies were included. Participants were assessed for core PTSD symptoms using the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5 and the Clinician-Administered PTSD Scale, as well as related symptoms, such as sleep issues. Although the efficacy of acupuncture has been substantiated in numerous studies, certain metrics did not exhibit improvement. Auricular acupuncture was the most commonly used treatment (50%) followed by manual acupuncture (25%) and a combination of both (25%). Shenmen and Kidney points were frequently targeted at auricular acupoints. The treatment period varied between 5 days and 2 months. While adverse events were reported in two of the fifty-five patients in the intervention group and in four of the sixty-four patients in the control group in the randomized controlled trial studies, no fatal adverse events were reported.

Written Exposure Therapy vs Prolonged Exposure Therapy in the Treatment of Posttraumatic Stress Disorder: A Randomized Clinical Trial

Importance

Evidence-based treatments for posttraumatic stress disorder (PTSD) exist, but all require 8 to 15 sessions and thus are less likely to be completed than brief treatments. Written exposure therapy (WET) is a brief and efficacious treatment that has not been directly compared with prolonged exposure therapy (PE), a more time-intensive, exposure-based treatment.

Objective

To determine whether WET is noninferior to PE in treating PTSD among veterans.

Design, Setting, and Participants

A randomized noninferiority clinical trial was conducted between September 9, 2019, and April 30, 2022. Participants were 178 veterans with PTSD presenting to 1 of 3 Veterans Affairs medical centers. Inclusion criteria consisted of a primary diagnosis of PTSD and stable medication. Exclusion criteria included current psychotherapy for PTSD, high suicide risk, active psychosis, unstable bipolar disorder, and severe cognitive impairment. Independent evaluations were conducted at baseline and 10, 20, and 30 weeks after the first treatment session. Data were analyzed from January 1 to March 31, 2023.

Interventions

Participants assigned to WET (n = 88) received five to seven 45- to 60-minute sessions. Participants assigned to PE (n = 90) received eight to fifteen 90-minute sessions. The WET sessions included 30 minutes of writing-based imaginal exposure conducted in session, whereas PE sessions included 40 minutes of in-session imaginal exposure and between-session in vivo exposures.

Main Outcomes and Measures

The primary outcome was change in PTSD symptom severity measured with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) from baseline to the 20-week assessment; noninferiority was defined as a less than 10-point difference between the 2 treatment groups. Difference in treatment dropout was also examined.

Results

Of the 178 participants, 134 (75.3%) were men, and the mean (SD) age was 44.97 (13.66) years. In terms of race, 37 participants (20.8%) were Black, 112 (62.9%) were White, 11 (6.2%) were more than 1 race, and 18 (10.1%) were of other race (including American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander [some participants did not specify their race when selecting the category "other"]); in terms of ethnicity, 19 participants (10.7%) were Hispanic. Changes in PTSD symptom severity from baseline to all subsequent assessments among individuals randomized to WET were noninferior relative to individuals randomized to PE. The largest difference between treatments was observed at 10 weeks and was in favor of WET (mean difference, 2.42 [95% CI, 0.35-1.46] points). Participants were significantly less likely to drop out of WET compared with PE (11 [12.5%] vs 32 [35.6%]; χ2 = 12.91; Cramer V = 0.27).

Conclusions and Relevance

In this study, WET was noninferior to PE in PTSD symptom change and was associated with significantly less attrition. Findings suggest that WET may transcend previously observed barriers to PTSD treatment for both patients and clinicians.

Psychological treatment of PTSD with comorbid substance use disorder (SUD): expert recommendations of the European Society for Traumatic Stress Studies (ESTSS)

Background: Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) are often comorbid and difficult to treat. The availability of evidence-based treatment guidelines is very limited and there is significant uncertainty about what best practice looks like.Objective: This paper describes the methodology used to develop expert recommendations for the assessment and psychological treatment of PTSD and comorbid SUD and presents the final recommendations.Methodology: A small committee of experts in the field of PTSD and SUD was formed on behalf of the European Society for Traumatic Stress Studies (ESTSS) Board. The committee developed recommendations based on a two-stage process. In the first stage a systematic review of randomised controlled trials of psychological interventions aimed at treating PTSD-SUD comorbidity was completed, and other recent relevant reviews systematic were also considered. To complement the recommendations based on systematic review, the second stage involved the review and collation of existing guidance, good practice and consensus recommendations made in methodologically rigorous clinical practice guidelines.Results: The two-stage process resulted in 9 recommendations related to assessment and 21 recommendations related to treatment planning and delivery.Conclusions: To our knowledge, this is the first attempt to provide expert recommendations based on a systematic review of the literature and through collation of guidance provided in other authoritative and reliable sources. These expert recommendations will provide helpful guidance to clinicians and service providers in both addiction and mental health settings about appropriate clinical care for those with PTSD SUD comorbidity.

Psychosocial interventions for survivors of rape and sexual assault experienced during adulthood

BACKGROUND

Exposure to rape, sexual assault and sexual abuse has lifelong impacts for mental health and well-being. Prolonged Exposure (PE), Cognitive Processing Therapy (CPT) and Eye Movement Desensitisation and Reprocessing (EMDR) are among the most common interventions offered to survivors to alleviate post-traumatic stress disorder (PTSD) and other psychological impacts. Beyond such trauma-focused cognitive and behavioural approaches, there is a range of low-intensity interventions along with new and emerging non-exposure based approaches (trauma-sensitive yoga, Reconsolidation of Traumatic Memories and Lifespan Integration). This review presents a timely assessment of international evidence on any type of psychosocial intervention offered to individuals who experienced rape, sexual assault or sexual abuse as adults.

OBJECTIVES

To assess the effects of psychosocial interventions on mental health and well-being for survivors of rape, sexual assault or sexual abuse experienced during adulthood.

SEARCH METHODS

In January 2022, we searched CENTRAL, MEDLINE, Embase, 12 other databases and three trials registers. We also checked reference lists of included studies, contacted authors and experts, and ran forward citation searches.

SELECTION CRITERIA

Any study that allocated individuals or clusters of individuals by a random or quasi-random method to a psychosocial intervention that promoted recovery and healing following exposure to rape, sexual assault or sexual abuse in those aged 18 years and above compared with no or minimal intervention, usual care, wait-list, pharmacological only or active comparison(s). We classified psychosocial interventions according to Cochrane Common Mental Disorders Group's psychological therapies list.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 36 studies (1991 to 2021) with 3992 participants randomly assigned to 60 experimental groups (3014; 76%) and 23 inactive comparator conditions (978, 24%). The experimental groups consisted of: 32 Cognitive Behavioural Therapy (CBT); 10 behavioural interventions; three integrative therapies; three humanist; five other psychologically oriented interventions; and seven other psychosocial interventions. Delivery involved 1 to 20 (median 11) sessions of traditional face-to-face (41) or other individual formats (four); groups (nine); or involved computer-only interaction (six). Most studies were conducted in the USA (n = 26); two were from South Africa; two from the Democratic Republic of the Congo; with single studies from Australia, Canada, the Netherlands, Spain, Sweden and the UK. Five studies did not disclose a funding source, and all disclosed sources were public funding. Participants were invited from a range of settings: from the community, through the media, from universities and in places where people might seek help for their mental health (e.g. war veterans), in the aftermath of sexual trauma (sexual assault centres and emergency departments) or for problems that accompany the experience of sexual violence (e.g. sexual health/primary care clinics). Participants randomised were 99% women (3965 participants) with just 27 men. Half were Black, African or African-American (1889 participants); 40% White/Caucasian (1530 participants); and 10% represented a range of other ethnic backgrounds (396 participants). The weighted mean age was 35.9 years (standard deviation (SD) 9.6). Eighty-two per cent had experienced rape or sexual assault in adulthood (3260/3992). Twenty-two studies (61%) required fulfilling a measured PTSD diagnostic threshold for inclusion; however, 94% of participants (2239/2370) were reported as having clinically relevant PTSD symptoms at entry. The comparison of psychosocial interventions with inactive controls detected that there may be a beneficial effect at post-treatment favouring psychosocial interventions in reducing PTSD (standardised mean difference (SMD) -0.83, 95% confidence interval (CI) -1.22 to -0.44; 16 studies, 1130 participants; low-certainty evidence; large effect size based on Cohen's D); and depression (SMD -0.82, 95% CI -1.17 to -0.48; 12 studies, 901 participants; low-certainty evidence; large effect size). Psychosocial interventions, however, may not increase the risk of dropout from treatment compared to controls, with a risk ratio of 0.85 (95% CI 0.51 to 1.44; 5 studies, 242 participants; low-certainty evidence). Seven of the 23 studies (with 801 participants) comparing a psychosocial intervention to an inactive control reported on adverse events, with 21 events indicated. Psychosocial interventions may not increase the risk of adverse events compared to controls, with a risk ratio of 1.92 (95% CI 0.30 to 12.41; 6 studies; 622 participants; very low-certainty evidence). We conducted an assessment of risk of bias using the RoB 2 tool on a total of 49 reported results. A high risk of bias affected 43% of PTSD results; 59% for depression symptoms; 40% for treatment dropout; and one-third for adverse events. The greatest sources of bias were problems with randomisation and missing outcome data. Heterogeneity was also high, ranging from I2 = 30% (adverse events) to I2 = 87% (PTSD).

AUTHORS' CONCLUSIONS

Our review suggests that survivors of rape, sexual violence and sexual abuse during adulthood may experience a large reduction in post-treatment PTSD symptoms and depressive symptoms after experiencing a psychosocial intervention, relative to comparison groups. Psychosocial interventions do not seem to increase dropout from treatment or adverse events/effects compared to controls. However, the number of dropouts and study attrition were generally high, potentially missing harms of exposure to interventions and/or research participation. Also, the differential effects of specific intervention types needs further investigation. We conclude that a range of behavioural and CBT-based interventions may improve the mental health of survivors of rape, sexual assault and sexual abuse in the short term. Therefore, the needs and preferences of individuals must be considered in selecting suitable approaches to therapy and support. The primary outcome in this review focused on the post-treatment period and the question about whether benefits are sustained over time persists. However, attaining such evidence from studies that lack an active comparison may be impractical and even unethical. Thus, we suggest that studies undertake head-to-head comparisons of different intervention types; in particular, of novel, emerging therapies, with one-year plus follow-up periods. Additionally, researchers should focus on the therapeutic benefits and costs for subpopulations such as male survivors and those living with complex PTSD.

A randomized clinical trial comparing Interpersonal Psychotherapy with Prolonged Exposure for the treatment of PTSD in veterans

Trauma-focused therapies are recommended as first-line treatments for posttraumatic stress disorder (PTSD), but many veterans do not complete or sufficiently respond to these treatments. Interpersonal Therapy (IPT) is a non-trauma focused approach that directly addresses the interpersonal and social impairments associated with PTSD. This two-site randomized controlled equivalence trial compared IPT with Prolonged Exposure (PE) in improving PTSD symptoms and interpersonal functioning in 109 veterans with PTSD. Secondary outcomes included functioning and quality of life. We hypothesized that IPT would be statistically equivalent to PE in reducing PTSD symptoms, and superior to PE in improving interpersonal functioning and secondary outcomes of work and social adjustment and quality of life. PTSD symptom severity decreased significantly in both treatments from pre- to post-treatment. Although IPT improved as much as PE and treatments did not differ significantly, the 95 % confidence interval for the difference between the groups did not fall completely within the margin of equivalence. IPT was not superior to PE in improvement in interpersonal functioning or on secondary outcomes. Findings from multi-level linear mixed models using longitudinal data (posttreatment, three and six month follow up) for the primary outcomes of PTSD and interpersonal functioning were consistent with the post-treatment analyses. Although statistically inconclusive in terms of equivalence, the comparable reduction in PTSD symptoms slightly favoring IPT suggests that IPT is an acceptable alternative to gold-standard trauma-focused treatments for veterans with PTSD.

The role of psychotherapists' perceived barriers in providing psychotherapy to refugee patients

Access to psychotherapy is critical to improving mental health, but only a small proportion of refugees receive treatment in the regular psychotherapeutic care system in high-income countries. In previous research, outpatient psychotherapists reported several barriers to more frequent treatment of refugee patients. However, it is unclear to what extent these perceived barriers contribute to the poor provision of services to refugees. In a survey of N = 2002 outpatient psychotherapists in Germany, we collected data on perceived treatment barriers and on the integration of refugees into regular psychotherapeutic practice. Half of the psychotherapists reported that they do not treat refugee patients. In addition, therapies provided for refugees were, on average, 20% shorter than for other patients. Regression analyses showed direct negative associations between psychotherapists' overall perception of barriers with the number of refugees treated and the number of sessions offered to refugee patients, even when controlling for sociodemographic and workload-related characteristics. Correlation analyses on the level of specific types of barriers further revealed that particularly language-related barriers and lack of contact with the refugee population are negatively correlated with the number of refugees treated and the number of sessions for refugees. Our findings indicate that the integration of refugees into regular psychotherapeutic care could be improved by measures to connect psychotherapists with refugee patients as well as professional interpreters and to ensure coverage of costs for therapy, interpreters and related administrative tasks.

Mind-body exercise interventions for prevention of post-traumatic stress disorder in trauma-exposed populations: a systematic review and meta-analysis

OBJECTIVE

Mind-body exercise (MBE) interventions, such as yoga, are increasingly recognised as an adjunct treatment for trauma-related mental disorders but less is known about their efficacy as a preventative intervention. We aimed to systematically review if, and what type of, MBE interventions are effective at preventing the development of post-traumatic stress disorder (PTSD) or acute stress disorder (ASD) in trauma-exposed populations.

DESIGN

Systematic review and meta-analysis.

METHODS

A systematic search of MEDLINE, PsycINFO, EMBASE and CENTRAL databases was conducted to identify controlled trials of MBE interventions aimed at preventing the development of PTSD or ASD in high-risk populations. Risk of bias was assessed using the revised Cochrane risk-of-bias and ROBINS-I tools. Pooled effect sizes using Hedges' g and 95% CIs were calculated using random effects modelling for the main meta-analysis and planned subgroup and sensitivity analyses.

RESULTS

Six studies (N analysed=399) were included in the final meta-analysis. Overall, there was a small effect for MBE interventions in preventing the development of PTSD (g=-0.25, 95% CI -0.56 to 0.06) among those with previous or ongoing exposure to trauma. Although a prespecified subgroup analyses comparing the different types of MBE intervention were conducted, meaningful conclusions could not be drawn due to the small number of studies. None of the included studies assessed ASD symptoms.

CONCLUSION

Limited evidence was found for MBE interventions in reducing PTSD symptomology in the short term. Findings must be interpreted with caution due to the small number of studies and possible publication bias.

Comparison of behavioral activation-enhanced cognitive processing therapy and cognitive processing therapy among U.S. service members: A randomized clinical trial

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) frequently co-occur and can cause significant impairment. Data are lacking as to whether interventions targeting both PTSD and MDD may improve treatment outcomes among individuals with this comorbidity compared with existing evidence-based PTSD treatments alone. This randomized trial compared the effectiveness of cognitive processing therapy (CPT) enhanced with behavioral activation (BA+CPT) versus CPT among 94 service members (52 women and 42 men; age M = 28.5 years) with comorbid PTSD and MDD. The primary outcome was clinician-administered depression symptom severity on the Montgomery-Åsberg Depression Rating Scale (MADRS) from pretreatment through 3-month follow-up. Intent-to-treat analyses using multilevel models showed statistically and clinically significant decreases in MADRS scores for both conditions over time, with no significant differences between BA+CPT and CPT. Secondary depression and PTSD symptom outcomes followed a similar pattern of results. For diagnostic MDD and PTSD outcomes using available data, no statistically significant differences between treatments emerged at posttreatment or 3-month follow-up. Sessions attended, dropout rate, and treatment satisfaction did not significantly differ between treatments. Outcomes were comparable for both treatments, suggesting that BA+CPT and CPT were similarly effective psychotherapy options for comorbid PTSD and MDD.

Cognitive behavior therapy for adult post-traumatic stress disorder in routine clinical care: A systematic review and meta-analysis

Although different cognitive behavioral therapies (CBT) have strong research support for treatment of adult post-traumatic stress disorder (PTSD) more knowledge is needed about the performance of CBT in routine clinical care. The present study is a systematic review and meta-analysis of CBT for PTSD in adults treated in routine clinical care. Ovid MEDLINE, Embase OVID, and PsycINFO were systematically searched for studies published until the end of May 2022. The effectiveness of CBT, methodological quality, and moderators of treatment outcome were examined, and benchmarked by meta-analytically comparing with efficacy studies for PTSD. Thirty-three studies, comprising 6482 participants, were included. The within-group effect sizes (ES) for PTSD-severity at post-treatment (1.75), and follow-up (1.70), on average 6 months post-treatment, were large. The effectiveness studies had very similar ESs as efficacy studies at post-treatment (1.75 vs. 1.72) and follow-up (1.70 vs. 2.02), based on the benchmarking analysis. As the heterogeneity was large, we can only cautiously consider CBT for PTSD an effective treatment when delivered in routine clinical care. The outcomes of effectiveness studies for PTSD seem to be comparable to the results obtained in efficacy studies. PROSPERO REGISTRATION ID: CRD42021228828.

PROTOCOL: Group-based interventions for posttraumatic stress disorder: A systematic review and meta-analysis of the role of trauma type

This is the protocol for a Campbell systematic review. The primary objective is to assess the effects of group-based treatments on posttraumatic stress disorder (PTSD) symptomology in people diagnosed with PTSD (by a clinician or screening instrument) or referred to a PTSD treatment group for their symptoms by a medical professional. We will also examine a range of moderators that may affect the efficacy of group-based treatments, including the nature of the trauma (interpersonal, stigmatized) and the group fit (in terms of gender and shared vs. unshared trauma). Further, we will also explore what, if any, group-based and social identity factors are recorded and how they relate to PTSD outcomes.
