A meta-analytic review of cognitive processing therapy for adults with posttraumatic stress disorder

Unravelling the impact of prior depression and trauma-related cognitive processes on depression following trauma: A 2-year prospective study of burn survivors

OBJECTIVE

Individuals with severe burn injuries may develop depression, yet knowledge about psychological risk factors for depression following trauma is limited. This study investigated the prospective impact and interplay of prior depression and trauma-related cognitive processes (posttraumatic negative appraisals and trauma-related rumination) to depressive symptoms between 6 and 24 months after burn injury.

METHOD

Taiwanese adult survivors of burn (N = 118) participated in surveys immediately post-burn and at 6-, 12-, and 24-months follow-up. Participants were 7 5% men, with an average age of 41.8 years and an average of TBSA of 18.3%.

RESULTS

A total of 8.5%, 5.9%, and 4.2% met criteria for probable major depression at 6, 12, and 24 months post-burn, respectively. The prevalence increased to 23.7%, 11.0%, and 5.9% using the cutoff on the PHQ-9. Prior depression and trauma-related cognitive processes immediately post-burn explained 13.5%, 20.5%, and 18.6% of the variance in depressive symptoms at 6, 12, and 24 months post-burn, respectively. Posttraumatic negative appraisals strongly predicted depressive symptoms post-burn across follow-ups. Moreover, posttraumatic negative appraisals significantly mediated the effect of prior depression on subsequent depressive symptoms across follow-ups. Prior depression significantly moderated the effect of trauma-related rumination on depressive symptoms at 6 months post-burn.

CONCLUSIONS

Our results are the first to demonstrate the role and interplay of prior depression and trauma-related cognitive processes in post-burn depression. Findings highlight that pre-and post-trauma psychological factors jointly affect depression following trauma, broadening the applicability of cognitive theories of PTSD.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Massed written exposure therapy delivered to veterans with posttraumatic stress symptoms on an acute inpatient mental health unit

Written exposure therapy (WET) is a brief, manualized trauma-focused treatment typically delivered in five individual weekly sessions. Given the brevity and effectiveness of WET, researchers have begun to focus on its delivery in a massed format. However, only one case study examining massed delivery has been published to date. As such, the objective of the current study was to examine the acceptability, feasibility, and preliminary effectiveness of massed WET among veterans with a trauma- and stressor-related disorder receiving care on an acute inpatient mental health unit. Veterans (N = 26) were assessed prior to, immediately after, and 1 month following massed WET. Most veterans found massed WET to be useful and acceptable. Recruitment and retention rates suggested that the treatment was feasible. Notably, the results revealed statistically significant reductions in overall posttraumatic stress symptoms, ηp 2 = .81, p < .001; depressive symptoms, ηp 2 = .71, p < .001; and functional impairment, ηp 2 = .42, p = .002. These findings add to a growing body of literature highlighting the preliminary effectiveness of WET across various settings, populations, and delivery formats. Limitations include the small sample size and uncontrolled design.

Is factor analysis useful for revising diagnostic criteria for PTSD? A systematic review of five issues ten years after DSM-5

BACKGROUND

Based on factor analysis research, DSM-5 revised the diagnostic criteria for posttraumatic stress disorder (PTSD) by increasing symptom clusters from three to four.

AIMS

To question whether that is an appropriate use of factor analysis.

METHODS

Reviewed the literature on five issues of factor analysis relevant to diagnostic criteria: (1) discovery of factors identical to symptom clusters, (2) consensus about the number of factors in best-fitting models, (3) configural variance between subpopulations to explain inconsistent model results, (4) methods to externally validate factors after discovery, and (5) treatment response of symptom clusters to externally validate factors. Two hundred four articles using DSM-IV or DSM-5 symptoms were included.

RESULTS

Two of four DSM-5 clusters were discovered with exploratory factor analysis. Support for a best-fitting model was inconsistent. Models with the highest number of factors were the best mathematical fit 87% of the time. Subpopulations did not reveal a pattern of configural variance to explain inconsistent findings. External validation of factors relied entirely on questionnaires. A review of 143 randomized controlled trials did not reveal differential treatment response of any symptom cluster.

CONCLUSION

Findings did not support the usefulness of factor analysis because the findings are too disparate to be helpful.

Impact of cognitive behavioural therapy on neural, inflammatory, & autonomic markers in a sample with PTSD and cardiovascular risk: protocol for a pilot randomised controlled trial

Background: Individuals with posttraumatic stress disorder (PTSD) are at heightened risk for cardiovascular disease (CVD) compared to the general population. Inflammation and autonomic dysfunction are candidate mechanisms of CVD risk in PTSD; however, these mechanisms have not been well-characterised in the PTSD-CVD link. Further, these mechanisms may operate through altered stress-related neural activity (SNA). Yet, it remains unknown if changes in PTSD are associated with changes in CVD risk mechanisms.Objective: This manuscript describes the design and procedures of a pilot randomised controlled trial to assess the impact of a first-line treatment for PTSD (Cognitive Processing Therapy; CPT) versus waitlist control on mechanisms of CVD risk. Further, this study will test the hypothesis that CPT reduces CVD risk through its effects on inflammation and autonomic function and that these changes are driven by changes in SNA.Methods: Adults with PTSD and CVD risk (N = 30) will be randomised to CPT or waitlist control. Participants complete two laboratory visits (baseline and post-treatment) that include surveys, brain and peripheral imaging via 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and resting measures of autonomic function. Primary outcomes include arterial inflammation and heart rate variability. Secondary outcomes include leukopoiesis (bone marrow uptake), heart rate, and blood pressure. The indirect effects of PTSD treatment on changes in inflammation and autonomic function through SNA will also be examined.Conclusions: This study seeks to characterise candidate neuroimmune mechanisms of the PTSD-CVD link to identify treatment targets and develop personalised interventions to reduce CVD events in PTSD populations.Trial registration: ClinicalTrials.gov identifier: NCT06429293..

Testing predictions from the memory and identity theory of ICD-11 complex posttraumatic stress disorder: Measurement development and initial findings

BACKGROUND

The 'Memory and Identity Theory' of ICD-11 Complex Posttraumatic Stress Disorder (CPTSD) was recently published but has not yet been subjected to empirical testing. The objective of this study was to evaluate newly developed measures of memory and identity disturbances and test hypothesized structural relations between these constructs and CPTSD symptoms.

METHODS

Self-report data were collected from a nationwide sample of adults living in Ukraine (N = 2050) in September 2023. Exploratory factor analysis was used to assess the latent structure of the newly developed measures, and structural equation modeling was used to test the associations between memory and identity disturbances and CPTSD symptoms.

RESULTS

90 % of participants experienced a lifetime trauma, and 9.2 % screened positive for ICD-11 CPTSD. Results indicated that the newly developed measures of memory and identity problems possessed satisfactory psychometric properties, and all but one of the model-implied structural associations were observed.

CONCLUSION

This study provides initial empirical support for the Memory and Identity theory of ICD-11 CPTSD, indicating that the basis of this disorder lies in distinct memory and identity processes. Several effects not predicted by the theory were observed, and these can provide the basis for further model testing and refinement.

Childbirth as an anticipated trauma during pregnancy: pretraumatic stress symptoms in primiparous women

INTRODUCTION

Women can develop anticipated traumatic reactions related to the forthcoming delivery through "pretraumatic stress" symptoms. The present study aims at: a) exploring the frequency of probable pretraumatic stress disorder in primiparous pregnant women, b) evidencing associated features of pretraumatic stress symptoms and c) exploring which specific components of antenatal anxiety are associated with pretraumatic stress symptoms.

METHODS

A sample of 100 primiparous pregnant women completed an online questionnaire assessing pretraumatic stress, fear of childbirth, depressive and anxiety symptoms. Socio-demographic and pregnancy-related data were also gathered.

RESULTS

8 % of women met all criteria for probable pretraumatic stress disorder. Increased depressive symptoms (ß = 0.48, p< .05), childbirth concerns (ß = 0.47, p< .05) and worry about self (ß = 0.74; p< .05) were associated with the intensity of pretraumatic stress disorder symptoms.

CONCLUSION

This study contributes to the very limited literature on pretraumatic stress symptoms. Thus, it is noteworthy that pretraumatic stress is not a reactivation of a former postpartum PTSD or associated with a prior negative experience of childbirth. Future studies conducted on primiparous women with no history of traumatic exposure could allow to provide additional evidences of the existence of anticipated traumatic reactions of childbirth.

[Evidence-based psychotherapy of posttraumatic stress syndrome-An update]

BACKGROUND

The aim of this article is to summarize the current state of research on the effectiveness of psychotherapeutic treatment of posttraumatic stress disorder (PTSD).

METHODS

The results of current meta-analyses and trend-setting individual studies are summarized and the most important forms of intervention are explained.

RESULTS

The psychotherapeutic treatment methods for PTSD are very effective, the effect sizes are large and superior to those of pharmacotherapy. Trauma exposure and cognitive restructuring are most effective. Trauma-focused procedures are generally superior to other forms of psychotherapy. A range of different cognitive behavioral procedures as well as eye movement desensitization and reprocessing are recommended. The most recent initial findings confirm a very good effectiveness for imagery rescripting methods as protective interventions without a formal confrontation with trauma. Individual therapy works better than group psychotherapy. In the group setting cognitive processing therapy has proven to be the best intervention. Trauma-focused treatment should also be used when comorbid conditions such as schizophrenia, bipolar disorder or addiction are present.

DISCUSSION

Trauma-focused psychotherapy in an individual setting is the treatment of choice for PTSD. A large selection of effective methods and well-reviewed manuals are available. The German language S3 guidelines are currently being updated.

Are There Differences Among Evidence-Based Psychotherapies for Treating Different DSM-5 PTSD Symptom Clusters? A Systematic Review and Meta-analysis of Controlled Clinical Trials

ABSTRACT

Posttraumatic stress disorder (PTSD) is a heterogeneous disease defined by four Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) symptom clusters: reexperiencing, avoidance, negative alterations in cognitions and mood, and hyperarousal. There are effective evidence-based psychotherapies (EBPs) for PTSD. However, given the variety of PTSD clinical presentations, we conducted the first meta-analysis investigating whether DSM-5 PTSD symptom clusters show different responses to EBPs. We systematically reviewed the literature for controlled clinical trials in five databases, performed a meta-analysis, and evaluated the methodological quality of the studies. We screened 633 studies and included seven. Three showed high risk, two showed some concerns, and one showed a low risk of bias. The symptom clusters do not seem to respond differently to EBPs (SMD cluster B: -0.40; 95% confidence interval [CI], -0.87 to 0.08; cluster C: -0.49; 95% CI, -0.90 to -0.08; cluster D: -0.44; 95% CI, -0.94 to 0.05; cluster E: -0.54; 95% CI, -1.07 to -0.0), even when analyzed by the therapeutic focuses. The findings dovetail nicely with the network theory of PTSD symptom, as although it is a heterogeneous disorder, the EBPs seem to promote a kind of cascade of symptom improvement.

The use of practice assignments in cognitive processing therapy to promote cognitive and emotional change: A case study

Cognitive processing therapy (CPT) is a first-line treatment for posttraumatic stress disorder (PTSD). The primary goals of CPT are to identify and challenge dysfunctional cognitions resulting from the trauma to promote a more balanced set of beliefs and reduce manufactured emotions; encouraging expression of natural emotions further promotes symptom improvement. Between-session assignments (homework) are an integral part of learning and practicing the skills developed during CPT, and these assignments are theorized to reinforce the proposed mechanisms of symptom change. This article begins with a brief description of the theoretical foundations of CPT and an overview of the session content of the CPT protocol, followed by a case study illustrating the use of CPT with the written account (CPT + A) with a survivor of childhood sexual assault. Although the client demonstrated some avoidance, her successful completion of practice assignments throughout treatment allowed her to identify and examine thoughts contributing to feelings of guilt and self-blame as well as negative beliefs about the world. She was able to reduce her assimilated and overaccommodated stuck points to form a more balanced view of the trauma, and also process her natural emotions, resulting in a significant reduction of PTSD symptoms. The role of homework at each session and how the assignments addressed the proposed mechanisms of change in CPT are discussed, and recommendations to increase clients' engagement in practice assignments in CPT are provided.

Sleep Quality as a Critical Pathway Between Adverse Childhood Experiences and Multimorbidity and the Impact of Lifestyle

OBJECTIVES

This study aims to establish the effects of ACEs on multimorbidity through sleep quality and investigate whether lifestyle factors (e.g., eating habits and exercise) may influence this relationship among middle-aged and older adults.

METHODS

Participants were drawn from a cross-sectional sample of community dwelling older adults (N = 276, 55+) and three waves of data from the Midlife in the United States study (MIDUS, N = 843). We examined the direct and indirect effects of ACEs, sleep quality, and health conditions, as well as the conditional effects of physical activity and eating habits.

RESULTS

Across both samples, sleep quality mediated the relationship between ACEs and chronic health conditions. Moderating effects of unhealthy eating and physical activity differed between samples.

DISCUSSION

Sleep quality is an important pathway connecting ACEs and adult multimorbidity, and health behaviors may provide targets for intervention particularly in older adults.

Intensive Care Unit (ICU)-Related Post-traumatic Stress Disorder: A Literature Review

An intensive care unit (ICU) is a challenging environment characterized by frequent incidences of stressors and traumatic situations. Therefore, both patients and caregivers are at high risk of developing psychological disorders such as post-traumatic stress disorder (PTSD), anxiety, and depression. ICU-related PTSD is a significant concern that remains under-recognized. This literature review examines the current state of knowledge regarding ICU-related PTSD, including its prevalence, risk factors, clinical manifestations, and potential interventions. Key findings suggest that a considerable proportion of ICU survivors develop PTSD symptoms, which can significantly impact their quality of life and recovery. The most common predictors investigated for PTSD in ICU survivors are age, gender, pre-illness psychopathy, length of stay in the ICU, delirium, and sedative agents. The treatment and prevention strategies of ICU-related PTSD include psychological therapies and pharmacological and non-pharmacological treatments. Psychological interventions, including cognitive-behavioral therapy and pharmacotherapy, have shown promise in mitigating PTSD symptoms in ICU survivors. However, further research is needed to better understand the mechanisms underlying ICU-related PTSD and to develop targeted interventions to prevent and manage this debilitating condition.

The mediating role of posttraumatic stress disorder symptoms in pain cognitions among Veterans with chronic pain

Symptoms of posttraumatic stress disorder (PTSD) are highly prevalent among Veterans with chronic pain. Considerable research has examined the intersection of chronic pain and PTSD symptoms. However, it remains unclear whether changes in PTSD may potentially serve a mechanistic role in improving unhelpful pain cognitions for individuals with chronic pain. The present research contributes to the foundational knowledge by addressing this question. Baseline data from a randomized controlled trial targeting pain-related disability for Veterans (n = 103; mean age 43.66; SD = 10.17) with musculoskeletal pain and depression and/or PTSD symptoms were used. Cross-sectional mediation analyses showed that PTSD symptoms mediated the relationship between pain severity and pain catastrophizing, and between pain severity and pain acceptance. After controlling for depression, the mediation involving pain catastrophizing remained significant, while the mediation for pain acceptance did not. Although limitations exist, results point to several treatment recommendations, including ensuring that depressive affect, PTSD-specific symptoms, and attention to both body and mind are included in treatment. Results also provide preliminary evidence for examining these associations longitudinally to improve our understanding of this population and corresponding treatment recommendations.

A preliminary study on the effect of trauma-focused therapies on sexual dysfunctions in women with PTSD after childhood abuse

BACKGROUND

Posttraumatic stress disorder (PTSD) is often associated with female sexual dysfunctions (FSD). However, little is known about the impact of therapies for PTSD on FSD according to DSM-5 criteria.

AIM/OBJECTIVE

To examine if sexual functioning diagnosed according to DSM-5 criteria improves after treatment for PTSD in women with a PTSD diagnosis after interpersonal child abuse.

METHOD

FSD according to DSM-5 criteria were assessed with the structured clinical interview SISEX in N = 152 female participants (mean age = 36.5 years) of a large randomized controlled trial three months into treatment and after 15 months of receiving either dialectical behavior therapy for PTSD or cognitive processing therapy. Number of fulfilled FSD criteria and diagnostic status were compared from pre-to post-treatment using Poisson and negative binomial regression analyses and the McNemar test. The effect of treatment type on reduction of FSD symptoms and the association between reduction in PTSD symptoms and reduction in FSD symptoms were assessed.

RESULTS

From pre-to post-treatment, the number of fulfilled criteria for each FSD decreased (Incident rate ratios between 0.60 and 0.71, p between <. 001 and <0 .05). Less women met criteria for genito-pelvic pain/penetration disorder at post-treatment compared to pre-treatment (11.8 % vs. 6.6 %, p < .05). No difference was found between treatments in reduction of FSD symptoms. Reduction of PTSD symptoms was associated with greater decrease in FSD symptoms.

CONCLUSIONS

Our results suggest a positive association between effective PTSD treatments and improvements in sexual functioning of women with PTSD after child abuse.

A Narrative Commentary on the Use of a Rational Emotive Behavior Therapy-Informed Group to Address Irrational Beliefs, Posttraumatic Stress Disorder, and Comorbidities

Irrational beliefs of Demandingness, Catastrophizing, Low Frustration Tolerance, and Depreciation have demonstrated prevalence in disparate areas of life, including psychopathology, the military, politics, religion, and education. Individuals with mental health concerns, such as Post-Traumatic Stress Disorder (PTSD), endorse elevations in such thoughts compared to the general population. This commentary describes the rationale for focusing on irrational beliefs in efforts to address PTSD and presents the Rational Emotive Behavior Therapy (REBT)-Informed Group for PTSD as a potential novel application of a well-established intervention. In support of these suggestions, we present a narrative review of the published work on irrational beliefs and REBT tenets as relevant for PTSD. We then introduce and describe the REBT-Informed Group intervention, summarize the prior preliminary research conducted by our group, and present some novel data from a re-analysis of this prior work. We end with commentary related to future directions of REBT approaches for PTSD to address limitations and expand the impact of the treatment to military and other Veteran or civilian populations.

Posttraumatic growth-oriented peer-based training among U.S. veterans: evaluation of post-intervention and long-term follow-up outcomes

Introduction

Exposure to trauma among U.S. military veterans occurs at a high rate, often resulting in continued difficulty with emotional adjustment and a diagnosis of posttraumatic stress disorder (PTSD). The present study provides data from 184 U.S. military veterans who completed a manualized posttraumatic-growth oriented training program during an integrative seven-day retreat.

Methods

Data was collected at baseline, after program completion, and at 18-month follow-up.

Results

Results on primary outcomes indicated significant increases, with medium to large effect sizes, in growth related outcomes. Specifically, there was a significant increase in scores by 54% on the posttraumatic growth outcome measure (PTGI-X) from baseline (M = 50.2, SD = 31.1) to endpoint (M = 77.4, SD = 29.6), t(183) = -8.78, p < 0.001. Also, results indicate that immediately following training (Day 7), participants reported a significant decrease of 49% on the PCL-5 from baseline (M = 39.7, SD = 17.6) to endpoint (M = 20.1, SD = 13.2), t(183) = 11.75, p < 0.001. Depression subscale scores decreased by 60% from baseline (M = 8.0, SD = 5.2) to endpoint (M = 3.2, SD = 3.0), t(183) = 10.68, p < 0.001; Anxiety scores decreased by 28% from baseline (M = 5.8, SD = 4.3) to endpoint (M = 4.2, SD = 3.5), t(183) = 4.08, p < 0.001; and Stress scores decreased by 50% from baseline (M = 10.0, SD = 4.4) to endpoint (M = 5.0, SD = 3.3), t(183) = 12.21, p < 0.001. Eighteen-month follow-up data was available for 74 participants and indicated that all significant changes in growth-related outcomes were maintained. Further, all significant changes in symptomatology-related outcomes were also maintained at follow-up.

Discussion

These findings demonstrate both the immediate and the long-lasting impact of an integrative posttraumatic growth-oriented training program on psychological growth and PTSD symptom reduction among U.S. military veterans.

Pathways Linking Post-Traumatic Stress Disorder to Incident Ischemic Heart Disease in Women: Call to Action

Background

Post-traumatic stress disorder (PTSD) is associated with increased rates of incident ischemic heart disease (IHD) in women.

Objectives

The purpose of this study was to determine mechanisms of the PTSD-IHD association in women.

Methods

In this retrospective longitudinal cohort study, data were obtained from electronic health records of all U.S. women veterans who were enrolled in Veterans Health Administration care from January 1, 2000 to December 31, 2017. Propensity score matching was used to match women with PTSD to women without PTSD on age, number of prior Veterans Health Administration visits, and presence of various traditional and nontraditional cardiovascular risk factors at index visit. Cox regression was used to model time until incident IHD diagnosis (ie, coronary artery disease, angina, or myocardial infarction) as a function of PTSD and potential mediating risk factors. Diagnoses of IHD, PTSD, and risk factors were defined by International Classification of Diseases-9th or -10th Revision, and/or Current Procedural Terminology codes.

Results

PTSD was associated with elevated rates of developing each risk factor. Traditional risk factors (hypertension, hyperlipidemia, smoking, diabetes) accounted for 24.2% of the PTSD-IHD association, psychiatric risk factors (eg, depression, anxiety, substance use disorders) accounted for 33.8% of the association, and all 13 risk factors accounted for 48.5% of the association.

Conclusions

Traditional IHD risk factors explained a quarter of the PTSD-IHD association in women veterans, and over half of the risk of IHD associated with PTSD remained unexplained even when adjusting for a wide range of risk factors. To be actionable, factors underlying the remaining PTSD-IHD association warrant timely investigation.

Functional brain changes after alternative pharmacological interventions in posttraumatic stress disorder: A systematic review of clinical trials

BACKGROUND

Posttraumatic stress disorder (PTSD) is a complex and heterogeneous mental health condition that can develop after exposure to a traumatic event. Clinical trials have used alternative pharmacological agents to treat PTSD, but their associated neural correlates remain unclear. The present systematic review aims to summarize the changes in brain function associated with the use of these alternative pharmacological agents in PTSD.

METHODS

Clinical trials using functional magnetic resonance imaging, either at rest or during the performance of tasks, were included if they compared the effects of alternative pharmacological agents between PTSD patients and either trauma-exposed controls or never-exposed healthy controls.

RESULTS

Sixteen studies were included, of which 11 used intranasal oxytocin, 2 used hydrocortisone, and 3 used delta-9-tetrahydrocannabinol (THC). Oxytocin administration was associated with the normalization of functional connectivity between the ventromedial prefrontal cortex and amygdala as well as enhanced the function of brain regions specifically involved in emotion processing (e.g., amygdala), working memory (e.g., dorsolateral prefrontal cortex), and reward (e.g., putamen). Hydrocortisone did not influence brain function at rest or during the performance of an autobiographical memory task, whereas THC was associated with the reduction of the amygdala and increased medial prefrontal cortex activation.

CONCLUSIONS

This systematic review identified preliminary evidence for normalizing brain function after the use of alternative pharmacological agents. Importantly, sex-specific differences were noted, in particular when using oxytocin, that will require further investigation.

Comparative effectiveness of psychotherapies in adults with posttraumatic stress disorder: a network meta-analysis of randomised controlled trials

BACKGROUND

Evidence on the long-term comparative effectiveness of posttraumatic stress disorder (PTSD) psychotherapies in adults remains unknown. Therefore, we performed an extensive network meta-analysis of randomised controlled trials (RCTs) to determine the comparative effectiveness of psychotherapies for people diagnosed with PTSD.

METHODS

A comprehensive search was conducted in Cochrane library, Embase, Medline-OVID, PubMed, Scopus, and Psych-Info until March 2021. Studies on the effectiveness of cognitive processing therapy (CPT), cognitive therapy (CT), eye movement desensitisation reprocessing (EMDR), narrative exposure therapy (NET), prolonged exposure (PE), cognitive behavioural therapy (CBT), present-centred therapy (PCT), brief eclectic psychotherapies (BEP), psychodynamic therapy (PDT) or combination therapies compared to no treatment (NT) or treatment as usual (TAU) in adults with PTSD were included. Frequentist and Bayesian approaches were used for analysis in R-software.

RESULTS

We included 98 RCTs with 5567 participants from 18 897 studies. CPT, EMDR, CT, NET, PE, CBT, and PCT were significant to reduce PTSD symptoms (SMD range: -1.53 to -0.75; Certainty: very low to high) at immediate post-treatment and ranked accordingly. Longitudinal analysis found EMDR (1.02) and CPT (0.85) as the significant therapies with large effect size in short-term and long-term follow-up, respectively. NET and CPT showed higher proportion of loss of PTSD diagnosis (RR range: 5.51-3.45) while there were no significant psychotherapies for retention rate compared to NT.

CONCLUSIONS

Our findings provide evidence for improving current guidelines and informing clinical decision-making for PTSD management. However, the best PTSD treatment plan should be tailored to patients' needs, characteristics, and clinician expertise.

Narrative-based autobiographical memory interventions for PTSD: a meta-analysis of randomized controlled trials

Introduction

The aim of this systematic review and meta-analysis is to evaluate the efficacy of narrative-based interventions (NBIs) for individuals with post-traumatic stress disorder (PTSD). Investigating the efficacy of NBIs should yield insight on autobiographical memory (AM) phenomena implicated in PTSD onset and recovery, leading to improved intervention protocols. Furthermore, by analyzing how NBIs influence maladaptive AM distortions, we hope to shed light on the theorized narrative architecture of AM more generally.

Methods

A systematic literature search was conducted according to PRISMA and Cochrane guidelines in MEDLINE, EMBASE, PsychINFO, and PubMed. Additional studies were then also identified from the reference lists of other relevant literature and considered for inclusion. Studies were then evaluated for adherence to the inclusion/exclusion criteria and assessed for risk of bias. Various meta-analyses were performed on included studies to understand how NBIs may or may not influence the overall effect size of treatment.

Results

The results of the meta-analysis of 35 studies, involving 2,596 participants, suggest that NBIs are a viable and effective treatment option for PTSD, yielding a statistically significant within-group effect size and decrease in PTSD symptomatology at both post-treatment [g = 1.73, 95% CI (1.23-2.22)] and 3-9 month follow-up assessments [g = 2.33, 95% CI (1.41-3.26)]. Furthermore, the difference in effect sizes between NBIs compared to active and waitlist controls was statistically significant, suggesting that NBIs are superior. Sub-analyses showed that NET provided a stronger effect size than FORNET, which may be due to the nature of the traumatic event itself and not the treatment protocol. While evidence of small study and publication bias was present, a weight-function model and trim-and-fill method suggested it was not influencing the overall results.

Discussion

This meta-analysis presents strong evidence supporting the use of NBIs in the treatment of PTSD. Clear similarities can be identified between NBIs included in this analysis that make them distinct from non-NBI interventions, which are reviewed in the discussion. Controlled comparisons between NBIs and non-NBIs would help to further understand AM mechanisms of action implicated in recovery and how various interventions facilitate them. Future research should also aim to elucidate the full range of AM impairment in individuals with PTSD to gain insight on how other memory capabilities, such as the ability to mentally simulate the future, are implicated in the pathogenesis of PTSD.

Moving toward precision PTSD treatment: predicting veterans' intensive PTSD treatment response using continuously updating machine learning models

BACKGROUND

Considerable heterogeneity exists in treatment response to first-line posttraumatic stress disorder (PTSD) treatments, such as Cognitive Processing Therapy (CPT). Relatively little is known about the timing of when during a course of care the treatment response becomes apparent. Novel machine learning methods, especially continuously updating prediction models, have the potential to address these gaps in our understanding of response and optimize PTSD treatment.

METHODS

Using data from a 3-week (n = 362) CPT-based intensive PTSD treatment program (ITP), we explored three methods for generating continuously updating prediction models to predict endpoint PTSD severity. These included Mixed Effects Bayesian Additive Regression Trees (MixedBART), Mixed Effects Random Forest (MERF) machine learning models, and Linear Mixed Effects models (LMM). Models used baseline and self-reported PTSD symptom severity data collected every other day during treatment. We then validated our findings by examining model performances in a separate, equally established, 2-week CPT-based ITP (n = 108).

RESULTS

Results across approaches were very similar and indicated modest prediction accuracy at baseline (R2 ~ 0.18), with increasing accuracy of predictions of final PTSD severity across program timepoints (e.g. mid-program R2 ~ 0.62). Similar findings were obtained when the models were applied to the 2-week ITP. Neither the MERF nor the MixedBART machine learning approach outperformed LMM prediction, though benefits of each may differ based on the application.

CONCLUSIONS

Utilizing continuously updating models in PTSD treatments may be beneficial for clinicians in determining whether an individual is responding, and when this determination can be made.

Do treatments for mental disorders affect relationship satisfaction? A systematic review and meta-analysis

Objective: Psychiatric disorders have been linked to poor social functioning, including deficits in relationship satisfaction. Treatments have shown strong effectiveness in reducing clinical symptoms for a range of disorders, though less is known of the effects disorder-focused treatments have on relationship satisfaction.

Methods: The present study describes a systematic review that was conducted to determine the efficacy of treatments for specific psychiatric disorders in improving relationship satisfaction. Surprisingly, only seventeen studies were identified and included in the review.

Results: We found that a majority of these studies reported modest improvement in relationship satisfaction among people who completed treatment. However, studies were severely hampered by methodological limitations, and all therapy-related improvements could be attributable to placebo effects or the passage of time.

Conclusion: Important gaps in the literature were found that future research should seek to address to maximize treatment outcomes and psychosocial functioning.

Comparative effectiveness of group v. individual trauma-focused treatment for posttraumatic stress disorder in veterans

BACKGROUND

Cognitive processing therapy (CPT) and prolonged exposure (PE) delivered in an individual setting are efficacious and effective treatments for veterans with posttraumatic stress disorder (PTSD). Group CPT has been shown to be less efficacious than individual CPT, however, evidence regarding real-world effectiveness is limited.

METHODS

We conducted a retrospective, observational, comparative effectiveness study including veterans that received at least eight sessions of group CPT, individual CPT, or individual PE, and were discharged from PTSD residential treatment at the Department of Veterans Affairs between 1 October 2015, and 30 September 2020. PTSD symptom severity was assessed with the PTSD Checklist for DSM-5 (PCL-5) and treatments delivered in a group (CPT) or individual (CPT or PE) setting were compared at discharge and 4-month post-discharge follow-up.

RESULTS

Of 6735 veterans, 3888 [653 women (17%), median (IQR) age 45 (35-55) years] received individual and 2847 [206 women (7.2%), median (IQR) age 42 (34-54)] received group therapy. At discharge, improvement in PTSD severity was statistically greater among those treated individually (mean difference on the PCL-5, 2.55 (95% CI 1.61-3.49); p = <0.001]. However, the difference was smaller than the minimal clinically important difference of 7.9 points. The groups did not differ significantly at 4-month follow-up [mean difference on the PCL-5, 0.37 (95% CI -0.86 to 1.60); p = 0.551].

CONCLUSION

Group CPT was associated with a slightly smaller reduction of PTSD symptom severity than individual CPT or PE in veterans at the end of residential treatment. There were no differences at 4-month follow-up.

Latent emotion profiles of PTSD and specific emotions predicting differential therapy outcomes in a dismantling study of cognitive processing therapy

Posttraumatic stress disorder (PTSD) is theoretically maintained by avoidance of emotions elicited from trauma-related beliefs. Whether PTSD symptom profiles and specific emotions predict treatment response is unknown. This secondary data analysis examined: a) whether individuals with PTSD can be sub-classified based on symptom clusters and specific emotions, and b) if these subgroups predict differential responses to cognitive versus exposure-based PTSD interventions. Women with physical or sexual assault-related PTSD were randomized to CPT (cognitive processing therapy elements only), CPT with written accounts (CPT+A), or written accounts (WA) only (n = 150). Participants completed baseline measures of PTSD, state anxiety, internalized anger, externalized anger, shame, and guilt, and weekly PTSD measures during and 6 months after treatment. Latent profile analyses revealed four subgroups: low symptoms and emotions; moderate-high reexperiencing, low internalized emotions (i.e., moderate-high reexperiencing, moderate avoidance/hyperarousal/guilt, low shame/internalized anger/anxiety); low reexperiencing, moderate emotions (i.e., low re-experiencing, moderate avoidance/hyperarousal/guilt, moderate other emotions); and high symptoms and emotions (high symptoms and emotions except moderate externalized anger). The high symptom and emotion subgroup experienced greater PTSD symptom improvements in cognitive conditions than WA. Other groups did not exhibit differential change across conditions. Cognitive interventions may be well-suited for severe PTSD with high self-directed emotions. CLINICALTRIALS.GOV IDENTIFIER: NCT00245232.

The role of symptom accommodation in trauma-focused treatment engagement and response

Although trauma-focused treatments (TFTs) are generally effective, not all patients improve. Symptom accommodation (i.e., altering one's behavior in response to another's symptoms) by loved ones may be particularly relevant to TFT treatment response and engagement. We examined the role of symptom accommodation by support persons (SPs) in veterans' PTSD treatment response, including the mediating role of treatment engagement and the moderating role of relationship strain. Veterans engaging in prolonged exposure or cognitive processing therapy and a loved one (N = 172 dyads) were sampled at two time points approximately four months apart. Measures of treatment engagement (i.e., highest session completed from the treatment protocol and homework completion) were obtained from hospital records. We found that relationship strain moderated the effect of symptom accommodation on treatment response, ∆R² = .02. Specifically, Time 1 (T1) accommodation predicted poorer treatment response (i.e., Time 2 [T2] PTSD symptom severity, controlling for T1 symptoms) among veterans who reported below-average relationship strain only. Additionally, symptom accommodation was indirectly related to treatment response such that T1 accommodation predicted higher T2 PTSD symptom severity specifically through reduced homework completion, β = .01. The findings suggest that attending to accommodating behaviors of veterans' supportive partners may be an important way to boost both engagement in and response to TFTs for PTSD.

Examining trauma cognition change trajectories among initial PTSD treatment non-optimal responders: a potential avenue to guide subsequent treatment selection

BACKGROUND

Despite their general effectiveness, 14-50% of individuals do not fully respond to evidence-based treatments for posttraumatic stress disorder (PTSD). Although changes in negative posttrauma cognitions (NPCs) are considered a likely PTSD treatment mechanism, less is known about how NPCs change among individuals who continue to be symptomatic following treatment (non-optimal responders).

OBJECTIVE

The objective of this study was to examine NPC change trajectories among individuals who were determined to be non-optimally responsive to intensive PTSD treatment.

METHOD

Using a 3-week Cognitive Processing Therapy-based intensive PTSD treatment sample (ITP; N = 243), the present study examined the number of distinct NPC change trajectories among non-optimal responders via Group Based Trajectory Modeling and assessed predictors of non-optimal responders' NPC change trajectory membership. Analyses were replicated in a separate 2-week ITP sample (N = 215).

RESULTS

In both non-optimal responder samples, two trajectories emerged; a no NPC change group which represented those with an overall lack of NPC change throughout treatment and an NPC change group which represented those with an overall reduction of NPCs occurring primarily later in treatment. Changes in PTSD symptom severity during treatment was the only consistent predictor of NPC change trajectory group membership among treatment non-optimal responders across ITPs.

CONCLUSIONS

Findings suggest NPC change among non-optimal responders is nuanced and may inform subsequent intervention selection, resulting in testable hypotheses for future research.

'Undoing a knot': a qualitative study of massed 1-week Cognitive Processing Therapy

Introduction: Intensive or massed Cognitive Processing Therapy (CPT) for posttraumatic stress disorder (PTSD) has been found to result in significant PTSD symptom reductions. However, few studies to date have used qualitative approaches to systematically evaluate client reflections about massed treatment approaches for PTSD. To address this gap, the present study aimed to improve our understanding of trauma survivors' reflections following the completion of 1-week CPT.Method: We conducted semi-structured interviews with seven trauma survivors within 3-months of the completion of 1-week CPT. We used the scissor-and-sort technique to identify themes and subthemes in the qualitative data.Results: Using the scissor-and-sort technique, we generated five main themes and associated subthemes from the data. The main themes were: (a) tangible skills, (b) feasibility, (c) therapeutic process, (d) symptom presentation, and (e) treatment expectations.Conclusion: Collectively, our results suggested that 1-week CPT was feasible and led to changes in PTSD symptoms and improved cognitive and affective coping skills.

Effects of Psychedelic Use on Racial Trauma Symptoms and Ethnic Identity among Asians in North America

There is a need to understand ways in which Asians in North America attempt to heal from racial trauma, given their well-documented high risk of exposure and associated adverse mental health outcomes. We conducted a secondary analysis of Asians from a survey of people of color in North America who have consumed psychedelics in response to racial discrimination. Ninety-two Asian participants (M_age = 30.25, SD = 6.83) completed online questions assessing demographics, racial discrimination frequency, characteristics and acute effects of their most meaningful psychedelic experience, change in racial trauma symptoms 30 days before and after their psychedelic experience, and current ethnic identity. Participants reported improvements in racial trauma symptoms (d = 0.52). Bootstrapped mediation analyses controlling for racial discrimination frequency and psychedelic dose and duration indicated complete mediation of the link between higher intensity of insightful experiences and stronger ethnic identity, via improvements in racial trauma symptoms (indirect effect = .08, 95% CI = [.004, .19]). There was partial mediation for the independent variable of lower intensity of challenging experiences (indirect effect = -.08, 95% CI = [-.18, -.005]). This study highlights the central role of higher-intensity insightful experiences and both higher- and lower-intensity challenging experiences in alleviating racial trauma symptoms and promoting ethnic identity among Asians in North America who have experienced racial discrimination. Future research should attune to culturally relevant outcomes of psychedelic use in response to racial discrimination among Asians.

Group Psychotherapy for Parents of Youth with Pediatric Acute-Onset Neuropsychiatric Syndrome

Parents of children with diagnoses of Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS) may experience significant psychological distress related to their child's severe and relapsing illness and challenges with the traumatic nature of its treatment. No manualized or studied psychological interventions specifically for parents of youth with PANS have existed prior to this study. In this pilot study, we assessed the feasibility, satisfaction, and treatment fidelity of a brief 9-session group therapy intervention for parents based on principles of trauma-focused cognitive behavior therapy (CBT). We hypothesized that, if initially elevated, symptoms of depression, anxiety, and trauma would decrease and participants' utilization of positive coping mechanisms would increase post-intervention. We adapted an existing evidence-based group intervention developed for parents of children with premature infants to target sources of stress and coping in parents of children with PANS. Ten parents participated in the study. The 9-session intervention used a combination of techniques that included cognitive restructuring, coping skills, self-care, and a trauma narrative to address psychological stress, trust, grief, and unwanted emotions. Outcome measures included parental symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD), as well as rating of parental satisfaction with the intervention. The treatment was feasible and deliverable with high fidelity. The intervention was rated as useful and satisfactory by parents (overall average usefulness of 4.54 and satisfaction of 4.71 out of 5.0). Elevated symptoms of PTSD and depression decreased with large effect sizes (Cohen's d = 1.42 and Cohen's d = 1.38, respectively). Participating parents demonstrated significantly more active coping and acceptance behaviors and stances. A brief 9-session group therapy intervention based on principles of trauma-focused CBT was found to be effective in reducing symptoms of psychological distress in parents of children with PANS.

Evaluating the attitudes of mental health professionals towards trials of MDMA: a randomised vignette trial

OBJECTIVES

To compare attitudes of mental health (MH) professionals towards trials of methylenedioxymethamphetamine-assisted psychotherapy (MDMA-AP), with a neutrally labelled pharmacotherapy trial.

DESIGN

A randomised controlled vignette study design, with experimenters blinded to group condition.

SETTING

Participants were recruited online via professional societies.

PARTICIPANTS

Psychiatrists, psychologists and MH researchers from across Australia.

INTERVENTIONS

Participants were randomly allocated to read a vignette about a trial of either MDMA-AP or a neutrally labelled pharmacotherapy.

OUTCOMES

Comparison of the difference in four attitudes towards MDMA-AP and control: How likely they were to (1) recommend participating, or (2) object to participating in the trial; (3) their predicted efficacy; and (4) concerns about the safety of the trial.

RESULTS

There were no overall differences between professional's attitudes towards MDMA-AP (n=51) and the control pharmacotherapy (n=43) trial vignettes. Psychiatrists were less likely to recommend participation in the MDMA-AP than the control trial (d=0.72, p=0.02), but did not differ in other attitudes. Psychologists and researchers did not differ in any attitudes. The correlation between professional experience and both: (1) concern about, and (2) strength of objection to, the trial, was higher for MDMA-AP, than control (d=0.60, p=0.01 and d=0.40, p=0.03, respectively).

CONCLUSIONS

Psychiatrists, but not psychologists or researchers showed more hesitancy in recommending trials of MDMA-AP versus an unknown pharmacotherapy. Experienced MH professionals were more likely to have negative views about MDMA-AP trials than less experienced MH professionals. This may reflect the experience of prior unfulfilled pharmacotherapy innovation or exuberance associated with fewer years of practice. Research into, and implementation of, MDMA-AP may face barriers with certain MH professionals, which will need be addressed if MDMA-AP continues to show promise as an efficacious treatment.

TRIAL REGISTRATION NUMBER

The study design was registered with the ANZCTR (ACTRN12620001068954).

Current Treatments of Post-traumatic Stress Disorder and Amygdala Ablation as a Potential Cutting-Edge Therapy in Its Refractory Cases

Post-traumatic stress disorder (PTSD)is a very common psychiatric disorder occurring in an individual of any age, gender, or race who underwent trauma, with women being twice more at risk than men. It is generally seen more in American Indians, United States Latinos, and African American ethnic groups. A patient is diagnosed with PTSD if the symptoms of intrusion, avoidance, changes in cognition and emotions, arousal, and mood reactivity changes persist for more than a month and cause the individual severe difficulty in their everyday cognitive and psychological functioning. The psychological treatment includes numerous therapies including trauma-focused therapies such as cognitive behavioral therapy, cognitive processing therapy, prolonged exposure therapy, eye movement desensitization and reprocessing, and non-trauma-focused therapies such as relaxation techniques, interpersonal therapy, and mindfulness. Various pharmacological measures have also been tried with mixed results such as selective serotonin reuptake inhibitors, benzodiazepines, adrenergic drugs, atypical antipsychotics, and mood stabilizers like lithium and valproate. As numerous studies have proven, PTSD is linked with right-side stimulation of the amygdala. The purpose of this article is to highlight the use of extremely selective laser ablation of the amygdala-hippocampal unit as a successful surgical intervention for medically unresponsive PTSD and as a revolutionary solution and prospective cutting-edge therapy in the near future.

Four profiles of symptom change in residential Cognitive Processing Therapy

A significant portion of veterans do not respond to evidence-based treatments for PTSD. Therefore, researchers have sought to predict who will respond well to trauma-focused treatment. The present study examined pre- and posttreatment symptom profiles, session-by-session change, as well as demographic and additional diagnostic information to better understand PTSD treatment response. Participants included 332 veterans undergoing residential Cognitive Processing Therapy. Latent profile analyses were computed, and four meaningful profiles emerged: Fast Responders, Steady Responders, Partial Responders, and Minimal Responders. Each profile demonstrated symptom reduction at approximately the same rate in the first half of treatment. Two specific profiles, Steady Responders and Minimal Responders, showed key clinically important differences. Both profiles demonstrated severe pretreatment PTSD symptom severity; however, in the second half of treatment, Steady Responders saw the steepest decrease in symptoms of any of the profiles while Minimal Responders saw less symptom reduction compared to all other profiles. Via a thorough examination, membership in Steady Responders compared to Minimal Responders was not associated with demographic or health variables. Results suggest that pretreatment symptom severity does not necessarily determine a client's posttreatment symptom severity. Pretreatment symptom severity did not determine outcome, though some veterans (Minimal Responders) did not experience the same symptom change and treatment effectiveness. Further identifying the factors that lead to the separation of these groups will add important information for determining treatment selection and potential obstacles to effectiveness.

Evidence-based posttraumatic stress disorder treatment in a community sample: Military-affiliated versus civilian patient outcomes

Posttraumatic stress disorder (PTSD) is a significant mental health issue among military service members and veterans. Although the U.S. Department of Veterans Affairs (VA) provides crucial resources for behavioral health care, many veterans seek mental health services through community clinics. Previous research illustrates that military and veteran patients benefit less from evidence-based treatments (EBTs) for PTSD than civilians. However, most PTSD treatment outcome research on military and veteran populations is conducted in VA or military settings. Little is known about outcomes among military-affiliated patients in community settings. The primary aim of this study was to directly compare civilian versus military-affiliated patient outcomes on PTSD and depression symptoms using the PTSD Checklist for DSM-5 (PCL-5) and the nine-item Patient Health Questionnaire (PHQ-9) in a community setting. Participants (N = 502) included military-affiliated (veteran, Guard/Reservist, active duty) and civilian patients who engaged in cognitive processing therapy (CPT) or prolonged exposure (PE) for PTSD in community clinics. Both groups demonstrated significant reductions on the PCL-5, military-affiliated: d = -0.91, civilian: d = -1.18; and PHQ-9, military-affiliated: d = -0.65, civilian: d = -0.88, following treatment. However, military-affiliated patients demonstrated smaller posttreatment reductions on the PCL-5, M_diff = 5.75, p = .003, and PHQ-9, M_diff = 1.71, p = .011, compared to civilians. Results demonstrate that military-affiliated patients benefit from EBTs for PTSD, albeit to a lesser degree than civilians, even in community settings. These findings also highlight the importance of future research on improving EBTs for military personnel with PTSD.

Adverse childhood experiences and body dysmorphic symptoms: A meta-analysis

Adverse childhood experiences (ACEs) are considered a risk factor for the development of various forms of mental disorders, including body dysmorphic disorder (BDD). The aim of the present work was to examine the association between ACEs and BDD symptomatology and to identify features of studies that might moderate this association. We conducted a three-level meta-analysis of 27 articles that included 9167 participants. Results showed that the types of ACE examined (total ACE, abuse, neglect, teasing, and bullying) were positively associated with BDD symptomatology. Specifically, a low to moderate association was found for ACE overall, defined as abuse, neglect, bullying, or teasing (r = 0.289, 95% confidence interval (CI) [.240,.337), for bullying (r = 0.282, 95% CI [.206,.354]), and for abuse (r = 0.223, 95% CI [.169,.276]) were found; and a moderate to large association was found for experienced teasing (r = 0.423, 95% CI [.360,.482]). In addition, moderator analyses of the association between ACE and BDD symptomatology resulted in a predictive model in which the type of ACE, type of sample, and gender of participants moderated the magnitude of the association between ACEs and BDD symptomatology.

A role for deficits in GABAergic neurosteroids and their metabolites with NMDA receptor antagonist activity in the pathophysiology of posttraumatic stress disorder

Trauma-focused psychotherapies show general efficacy in post-traumatic stress disorder (PTSD), although outcomes vary substantially among individuals with PTSD and many patients do not achieve clinically meaningful symptom improvement. Several factors may contribute to poor treatment response, including genetic or environmental (e.g., stress) effects on neurobiological factors involved in learning and memory processes critical to PTSD recovery. In this review, we discuss the relationship between deficient GABAergic neurosteroid metabolites of progesterone, allopregnanolone (Allo) and pregnanolone (PA), and PTSD symptoms in men and women or PTSD-like behavioral abnormalities observed in male rodent models of PTSD. We also review the role and molecular underpinnings of learning and memory processes relevant to PTSD recovery, including extinction, extinction retention, reconsolidation of reactivated aversive memories and episodic non-aversive memory. We then discuss preclinical and clinical research that supports a role in these learning and memory processes for GABAergic neurosteroids and sulfated metabolites of Allo and PA that allosterically antagonize NMDA receptor function. Studies supporting the possible therapeutic impact of appropriately timed, acutely administered Allo or Allo analogs to facilitate extinction retention and/or block reconsolidation of aversive memories are also reviewed. Finally, we discuss important future directions for research in this area. Examining the varied and composite effects in PTSD of these metabolites of progesterone, as well as neuroactive derivatives of other parent steroids produced in the brain and the periphery, will likely enable a broadening of targets for treatment development. Defining contributions of these neuroactive steroids to common PTSD-comorbid psychiatric and medical conditions, as well as subpopulation-specific underlying dysfunctional physiological processes such as hypothalamic-pituitary-adrenal axis and immune system dysregulation, may also enable development of more effective multisystem precision medicines to prevent and treat the broader, polymorbid sequelae of extreme and chronic stress.

Trauma-focused psychotherapies for post-traumatic stress disorder: A systematic review and network meta-analysis

INTRODUCTION

Meta-analytic reviews suggest similar outcomes across trauma-focused psychotherapies for adults with post-traumatic stress disorder (PTSD). However, this conclusion may be premature due to suboptimal statistical-review methodologies. Network meta-analysis (NMA) allows a detailed rank-ordering of the efficacy of established psychotherapy interventions derived from indirect evidence as well as results from direct head-to-head comparisons.

OBJECTIVE

We sought to determine the efficacy and attrition rates of psychotherapy interventions for PTSD by applying NMA.

METHODS

We searched EMBASE, PsychINFO, PTSDPubs and PubMed for randomised controlled trials that compared psychotherapies either head-to-head or against controls for adults with PTSD. A frequentist NMA was used to compare direct and indirect effects to determine the efficacy and attrition rates of psychotherapy interventions.

RESULTS

Of the 5649 papers identified, 82 trials comprising of 5838 patients were included. The network comprised 17 psychotherapies and four control conditions. Network estimates indicated superior efficacy of meta-cognitive therapy and cognitive processing therapy over other psychotherapies (ESs between = 0.26 and 2.32). Written exposure therapy and narrative exposure therapy were associated with lower risk of drop out when considered alongside other psychotherapies. Confidence in the network meta-analytic estimates was considered moderate for both outcomes.

CONCLUSIONS

In broad terms, therapeutic commensurability was evident. Nevertheless, with additional studies and larger sample sizes, meta-cognitive and written exposure therapies could indeed differentiate themselves from other approaches as having favourable efficacy and acceptability respectively. These findings may inform clinical decision-making, as well as guide future research for PTSD.

Understanding the association between material hardship and posttraumatic stress disorder: a test of the social selection and social causation hypotheses and an exploration of gender differences

PURPOSE

There is a well-established association between poverty and posttraumatic stress disorder (PTSD); however, little research has tested the temporality of the association.

METHODS

Using data from Waves IV (2008; N = 14,800) and V (2016-2018; N = 10,685) of the National Longitudinal Study of Adolescent to Adult Health, we examined temporal associations between material hardship (a specific operationalization of poverty) and PTSD, as well as assessed for potential gender differences in associations. We conducted logistic regression and generalized structural equation modeling to examine associations between material hardship and PTSD and assess for mediation and moderation by gender.

RESULTS

Prior PTSD diagnoses were associated with an increased likelihood of material hardship (OR = 1.64; 95% CI 1.21, 2.21). The indirect effect of gender on material hardship through PTSD diagnoses was significant. Prior material hardship was associated with an increased likelihood of PTSD diagnoses (OR = 1.81; 95% CI 1.35, 2.42). The indirect effect of gender on PTSD diagnoses through material hardship was significant. There was no evidence of moderation by gender for either association.

CONCLUSION

Results suggest reciprocal associations between material hardship and PTSD. Economic policies, as well as improved access to evidence-based PTSD treatments, may reduce the burden of both material hardships and PTSD.

Event centrality and post-traumatic stress symptoms among college students during the COVID-19 pandemic: the roles of attention to negative information, catastrophizing, and rumination

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has affected college students' mental health and caused post-traumatic stress symptoms (PTSS). Event centrality is thought to play a key role in the development of PTSS, but it is not yet clear by what mechanism. Theoretically, event centrality may affect the retrieval of traumatic memories and further prompt post-traumatic cognitions to understand events, and so may in turn be associated with PTSS in college students. However, few empirical studies have examined the mediating role of post-traumatic cognitions in the relationship between event centrality and PTSS, especially among college students during the COVID-19 pandemic.

OBJECTIVES

The objective of this study was to examine the mediating roles of post-traumatic cognitive factors (e.g. attention to negative information, catastrophizing, and rumination) in the relationship between event centrality and PTSS among college students during the COVID-19 pandemic.

METHODS

We recruited 1153 college students who completed the pandemic experiences scale, the centrality of event scale, the attention to positive and negative information scale, the cognitive emotion regulation questionnaire, and the PTSD Checklist for DSM-5 during the COVID-19 pandemic in May 2020.

RESULTS

In this sample of college students, event centrality directly predicted PTSS, and PTSS was also indirectly predicted by event centrality through attention to negative information, catastrophizing, and rumination.

CONCLUSIONS

These findings support the existing literature on the relationship between event centrality, proposed cognitive variables, and PTSS, and shed light on the mechanisms underlying PTSS. Our findings also highlight the importance and applicability of targeted cognitive interventions for PTSS in college students during the COVID-19 pandemic.

HIGHLIGHTS

The COVID-19 pandemic has caused post-traumatic stress symptoms among college students.Event centrality is a risk factor of post-traumatic stress symptoms among college students during the COVID-19 pandemic.Attention to negative information, catastrophizing and rumination mediate the relationship between event centrality and post-traumatic stress symptoms.

Application of the Nursing Model Based on Acceptance and Commitment Therapy (ACT) in Improving Mental Health and Quality of Life after Colorectal Cancer Drug Chemotherapy

According to the most current cancer impact statistics, third most commonly diagnosed cancer worldwide is colorectal cancer. Colon cancer, in addition to its physical symptoms, has been linked to mental health issues in patients, according to the study. Dealing with colorectal cancer drug chemotherapy may lead to depression and anxiety in some people. Others are affected by the physical and mental condition of undergoing many therapies at the same time. Throughout the process of diagnosis, a large number of colorectal cancer patients report clinically relevant degrees as well as a decline in overall mental wellness. In the majority of cases, colon cancer patients are cured following therapy, but those who have survived the disease confront a medical range, physical, and challenges in society, for a variety of mental and physical problems such as anxiety and depression. First, meditation therapy is to urge patients to address their issues and feelings instead of dismissing them, but in the dispassionate and unbiased manner that defines the attentive state. Both the patient and the treating professional may benefit from this treatment method, since it appears to be a very effective therapeutic strategy. After colorectal cancer treatment, in studies, it has been demonstrated that ACT improves mental health, and Internet search engines such as Web of Science and Google Scholar as well as Dialnet were utilized to conduct a systematic literature There were 19 articles that fit the criteria. This includes a discussion of the ACT's philosophical and theoretical basis, as well as the treatment itself. On the other hand, the study on ACT for enhancing mental health and quality of life is examined. Several of the available trials had serious flaws, making it impossible to establish reliable conclusions about the effectiveness of ACT for improving mental health and quality of life. The study determined that there is only a small amount of data supporting the use of ACT for improving mental health. The aim of this study is the application of the nursing model on improving the mental health of the colorectal patients. In addition, the limits of the current empirical state of ACT are acknowledged, and the importance of further research is highlighted.

Network Analysis of Neurobehavioral and Posttraumatic Stress Disorder Symptoms One Year after Traumatic Brain Injury: A Veterans Affairs TBI Model Systems Study

Traumatic brain injury (TBI) is often experienced under stressful circumstances that can lead to both symptoms of posttraumatic stress disorder (PTSD) and neurobehavioral symptoms of brain injury. There is considerable symptom overlap in the behavioral expression of these conditions. Psychometric network analysis is a useful approach to investigate the role of specific symptoms in connecting these two disorders and is thus well-suited to explore their interrelatedness. This study applied network analysis to examine the associations among PTSD and TBI symptoms in a sample of Service Members and Veterans (SM/Vs) with a history of TBI one year after injury. Responses to the Neurobehavioral Symptom Inventory (NSI) and PTSC Checklist-Civilian version (PCL-C) were obtained from participants who completed comprehensive inpatient rehabilitation services at five VA polytrauma rehabilitation centers. Participants (N = 612) were 93.1% male with an average age of 36.98 years at injury. The analysis produced a stable network. Within the NSI symptom groups, the frustration symptom was an important bridge between the affective and cognitive TBI symptoms. The PCL-C nodes formed their own small cluster with hyperarousal yielding connections with the affective, cognitive, and somatic symptom groups. Consistent with this observation, the hyperarousal node had the second strongest bridge centrality in the network. Hyperarousal appears to play a key role in holding together this network of distress and thus represents a prime target for intervention among individuals with elevated symptoms of PTSD and a history of TBI. Network analysis offers an empirical approach to visualizing and quantifying the associations among symptoms. The identification of symptoms that are central to connecting multiple conditions can inform diagnostic precision and treatment selection.

Interventions for addressing trauma among people with HIV: a narrative review

Traumatic experiences are disproportionately prevalent among people with HIV and adversely affect HIV-related health outcomes. As part of a national cooperative agreement funded by the Health Resources and Services Administration's HIV/AIDS Bureau, we searched the literature for interventions designed to address trauma among people with HIV in the U.S. Our search yielded 22 articles on 14 studies that fell into five intervention categories: expressive writing, prolonged exposure therapy, coping skills, cognitive-behavioral approaches integrated with other methods, and trauma-informed care. Thematic elements among the interventions included adaptating existing interventions for subpopulations with a high burden of trauma and HIV, such as transgender women and racial/ethnic minorities; addressing comorbid substance use disorders; and implementing organization-wide trauma-informed care approaches. Few studies measured the effect of the interventions on HIV-related health outcomes. To address the intersecting epidemics of HIV and trauma, it is critical to continue developing, piloting, and evaluating trauma interventions for people with HIV, with the goal of wide-scale replication of effective interventions in HIV settings.

Does attachment predict the outcome of cognitive processing therapy for posttraumatic stress disorder in adolescent patients with interpersonal traumatization?

The attachment has emerged as a significant predictor of psychotherapy outcome. However, studies on trauma-focused treatments and adolescent samples are sparse. We analyzed the data of 43 adolescents and young adults (aged 14-21 years) with clinically relevant abuse-related posttraumatic stress disorder (PTSD) who were undergoing developmentally adapted cognitive processing therapy (D-CPT) within a multicenter, randomized clinical trial (German Clinical Trials Register; identifier: DRKS00004787). Besides clinician-rated posttraumatic stress symptoms (PTSS), attachment-related (AR) anxiety and AR avoidance were assessed using self-reports before and after treatment as well as at three-month and six-month follow-ups. Baseline attachment did not predict any changes in PTSS severity. Averaging across all assessment points, overall higher posttraumatic avoidance was associated with greater baseline AR avoidance in D-CPT. In terms of change in attachment during the trial, a greater reduction of attachment insecurities was associated with a greater reduction of PTSS severity. Results are compared with those of the control group, a wait-list condition with treatment advice (WL/TA; N = 42). AR anxiety was more often a significant variable in the models in WL/TA, whereas AR avoidance was in D-CPT. Our study does furnish initial insights into the role of attachment during trauma-focused treatment with abused adolescents and young adults.Trial registration: German Clinical Trials Register identifier: DRKS00004787.

In Their Own Words: Veteran Experiences with Evidence-Based Treatments for PTSD in the Veterans Health Administration

The aim of the present study was to increase the understanding of veteran experiences with receiving an evidence-based psychotherapy (EBPs) for PTSD (Cognitive Processing Therapy and Prolonged Exposure therapy) in the Veterans Affairs Healthcare System (VA). Eighteen veterans who participated in the study were being seen in the outpatient PTSD clinic at a New England VA and had elected to participate in an EBP. The study assessed veteran experiences with, and outcomes from, treatment through the use of both quantitative and qualitative assessment tools. A rigorous data analytic approach, Consensual Qualitative Research, was applied to narrative data. Results fell into seven domains: Previous EBP & Outcome, Barriers to Treatment, Treatment Process, Treatment Outcome, Treatment Drop Out, and Feelings about Treatment. Overall, veterans reported diverse reactions to the EBPs for PTSD and identified both positive and negative aspects of the treatments. They identified multiple barriers to treatment completion and provided insight into their thoughts and feelings during the treatment protocol. Veterans who chose to drop out of treatment prematurely identified the factors that contributed to this decision. In this way, the study offers an initial but important look at veteran perceptions of and experiences with EBPs for PTSD.

The Effect of Therapeutic Alliance on Dropout in Cognitive Processing Therapy for Posttraumatic Stress Disorder

A substantial number of individuals who undergo cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) drop out before receiving a full course of treatment. Therapeutic alliance, defined as the working relationship between the therapist and client, is a dynamic process within therapy that may change over time. Research suggests that therapeutic alliance is associated with dropout in various treatments. However, no studies have yet examined the association between therapeutic alliance and dropout in CPT, and few studies have examined therapeutic alliance longitudinally over the course of treatment. Examining alliance in CPT through different methods may increase clinicians' understanding of how to tailor interventions to prevent treatment dropout. The present study examined the association between therapeutic alliance and treatment dropout among 169 participants in a randomized implementation effectiveness trial. In total, 33.1% of clients dropped out over the course of CPT, and nearly half of these individuals dropped out during the first six sessions. Continuous-time survival analysis results indicated that mean ratings of alliance significantly predicted treatment dropout, Wald χ² (1, N = 167) = 4.08, Exp(β) = .64, p = .043, whereas initial alliance, late alliance, and change in alliance over treatment did not. These findings suggest that overall therapeutic alliance is an important predictor of dropout from CPT.

Interpersonal Psychotherapy of Posttraumatic Stress Disorder for Veterans and Family Members: An Open Trial

OBJECTIVE

Military service members and veterans have high rates of posttraumatic stress disorder (PTSD), as do military family members. Exposure-based, cognitive-behavioral approaches have received ample research, but other PTSD therapies require further empirical attention. Interpersonal psychotherapy (IPT) targets affective awareness, life circumstances, and social support. IPT has shown efficacy for civilians with PTSD but awaits rigorous testing among military personnel; only two small military pilot studies and two case reports have been published. Military family members have received minimal attention from clinical outcomes research. Addressing these gaps, this open trial examined IPT for PTSD among veterans, service members, and family members, including a patient subset with comorbid PTSD and depression.

METHODS

Fifty U.S. military service members, veterans, and family members (age ≥18 years) were offered 14 sessions of IPT for PTSD. Individuals with psychosis, bipolar disorder, moderate or severe substance use disorders, or high suicide risk were excluded. PTSD and depressive symptoms were assessed at baseline, midtreatment, posttreatment, and 3-month follow-up.

RESULTS

Clinician-assessed PTSD (Clinician-Administered PTSD Scale) and depression (Hamilton Depression Rating Scale) symptoms decreased over time in the full sample and the comorbid PTSD/depression subset (p<0.05). Service members, veterans, and family members had similar treatment responses.

CONCLUSIONS

Patients receiving IPT showed reductions in PTSD and depressive symptoms. These open trial findings provide preliminary support for the utility of IPT in reducing PTSD symptoms among veterans and family members. This largest IPT trial to date for PTSD in military patients also bolsters the literature on treating military family members.

PTSD: Past, present and future implications for China

There has been a long history since human beings began to realize the existence of post-traumatic symptoms. Posttraumatic stress disorder (PTSD), a diagnostic category adopted in 1980 in the Diagnostic and Statistical Manual of Mental Disorders-Ⅲ, described typical clusters of psychiatric symptoms occurring after traumatic events. Abundant researches have helped deepen the understanding of PTSD in terms of epidemiological features, biological mechanisms, and treatment options. The prevalence of PTSD in general population ranged from 6.4% to 7.8% and was significantly higher among groups who underwent major public traumatic events. There has been a long way in the studies of animal models and genetic characteristics of PTSD. However, the high comorbidity with other stress-related psychiatric disorders and complexity in the pathogenesis of PTSD hindered the effort to find specific biological targets for PTSD. Neuroimage was widely used to elucidate the underlying neurophysiological mechanisms of PTSD. Functional MRI studies have showed that PTSD was linked to medial prefrontal cortex, anterior cingulate cortex and sub-cortical structures like amygdala and hippocampus, and to explore the functional connectivity among these brain areas which might reveal the possible neurobiological mechanism related to PTSD symptoms. For now, cognitive behavior therapy-based psychotherapy, including combination with adjunctive medication, showed evident treatment effects on PTSD. The emergence of more effective PTSD pharmacotherapies awaits novel biomarkers from further fundamental research. Several natural disasters and emergencies have inevitably increased the possibility of suffering from PTSD in the last two decades, making it critical to strengthen PTSD research in China. To boost PTSD study in China, the following suggestions might be helpful: (1) establishing a national psychological trauma recover project, and (2) exploring the mechanisms of PTSD with joint effort and strengthening the indigenized treatment of PTSD.
