Differential treatment response trajectories in individuals with subclinical and clinical PTSD

Clinical relevance of subthreshold PTSD versus full criteria PTSD following traumatic brain injury in U.S. service members and veterans

BACKGROUND

The purpose of this cross-sectional study was to examine the influence of subthreshold posttraumatic stress disorder (PTSD) and full PTSD on quality of life following mild traumatic brain injury (mTBI).

METHODS

Participants were 734 service members and veterans (SMV) classified into two injury groups: uncomplicated mild TBI (MTBI; n = 596) and injured controls (IC, n = 139). Participants completed a battery of neurobehavioral measures, 12-or-more months post-injury, that included the PTSD Checklist Civilian version, Neurobehavioral Symptom Inventory, and select scales from the TBI-QOL and MPAI. The MTBI group was divided into three PTSD subgroups: No-PTSD (n = 266), Subthreshold PTSD (n = 139), and Full-PTSD (n = 190).

RESULTS

There was a linear relationship between PTSD severity and neurobehavioral functioning/quality of life in the MTBI sample. As PTSD severity increased, significantly worse scores were found on 11 of the 12 measures (i.e.

, MTBI

Full-PTSD > Sub-PTSD > No-PTSD). When considering the number of clinically elevated scores, a linear relationship between PTSD severity and neurobehavioral functioning/quality of life was again observed in the MTBI sample (e.g., 3-or-more elevated scores: Full-PTSD = 92.1 %, Sub-PTSD = 61.9 %, No-PTSD = 19.9 %).

LIMITATIONS

Limitations included the use of a self-report measure to determine diagnostic status that may under/overcount or mischaracterize individuals.

CONCLUSION

PTSD symptoms, whether at the level of diagnosable PTSD, or falling short of that because of the intensity or characterization of symptoms, have a significant negative impact on one's quality of life following MTBI. Clinicians' treatment targets should focus on the symptoms that are most troubling for an individual and the individual's perception of quality of life, regardless of the diagnosis itself.

Identifying post-traumatic stress symptom typologies in clinical and non-clinical healthcare staff: a latent profile analysis

Background: There has been growing concern regarding increasing levels of post-traumatic stress (PTS) symptoms experienced by healthcare workers (HCW) in the UK, particularly following the COVID-19 pandemic.Objectives: PTS symptom typologies have been investigated in other adult populations using person-centred latent variable approaches, revealing profiles showing differing symptom levels and patterns. We aimed to explore typologies among clinical and non-clinical healthcare staff to elucidate heterogeneity of presentation.  Methods: This was a retrospective study using referral data from treatment-seeking healthcare staff in the North of England (N = 1600). We employed latent profile analysis using the PTSD International Trauma Questionnaire domains as profile indicators. We included covariates relating to role-type, depression, anxiety and mental health concerns before March of 2020.   Results: A model with six profiles fit the data best. Profile names were given as follows: 'No symptom'; 'Low symptom'; 'Low symptom (moderate Sense of current threat (Th_dx) and Functional impairment (FI))'; 'Moderate symptom (low Th_dx and high Avoidance (Av_dx))'; 'Moderate symptom'; and 'High symptom'. Covariates were shown to have differential predictive power on profile membership. Conclusions: The finding of profiles with pattern differences suggests a need for both differential and specifically targeted treatments, as well as a consideration of early intervention for those individuals with subclinical PTS symptoms. As expected, anxiety and depression were both predictors of several of the symptomatic profiles, with anxiety producing a larger effect. Further research is required to fully understand the link between role-type and PTS symptom typologies among HCW. .

Sexual Assault History May Moderate Posttraumatic Cognition and Posttraumatic Stress Among Trauma-Exposed Sexual Minority Women

Sexual minority women (SMW) are highly vulnerable to trauma exposure and posttraumatic stress disorder (PTSD) symptoms following trauma exposure. Negative posttraumatic cognitions (i.e., negative cognitions about self, world, and self-blame following trauma exposure) are hypothesized to exacerbate and maintain the relationship between trauma exposure and PTSD symptoms. Posttraumatic cognitions are particularly important to examine in relation to PTSD symptoms among trauma-exposed SMW given their elevated risk for trauma exposure and PTSD. It is also important to understand whether the strength of this relationship differs as a function of trauma type to elucidate potentially differential pathways for risk by trauma type in this population. The current study explored whether trauma type (sexual assault vs. nonsexual trauma) moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity among a sample of trauma-exposed SMW. Participants were SMW (n = 516) users of an online survey platform, Prolific. Data were collected via 20-minute online survey. Results indicated that trauma type moderated the relationship between negative posttraumatic cognitions and PTSD symptom severity, such that the relationship was stronger among those who had experienced at least one sexual assault in their lifetime. Results suggest that negative posttraumatic cognitions may be more strongly related to PTSD symptom severity among SMW who have experienced at least one sexual assault. Notably, this difference was in magnitude only, as the posttraumatic cognition-PTSD symptom relationship remained significant among nonsexual trauma survivors. Negative posttraumatic cognitions may be an especially relevant treatment target among SMW survivors of sexual assault.

Taken to the extreme: Transformational leadership, psychological capital, and follower health outcomes in extreme contexts

The purpose of this study is to examine the boundary conditions of transformational leadership, follower psychological capital, and their effects on follower mental health outcomes. Specifically, we utilize archival, multi-wave data from a military sample to examine whether the negative relationship between transformational leadership and adverse follower stress outcomes increases as the context shifts from a relatively safe environment to one in which follower lives are at risk. Additionally, psychological capital, a constellation of personal psychological resources, is also assessed to account for individual buffers against extreme stressors. Findings from the current study suggest that the negative relationship between transformational leadership and follower stress increases significantly when the context shifts to a high-risk, mortality-salient environment.

The efficacy and acceptability of group trauma-focused cognitive behavior therapy for the treatment of post-traumatic stress disorder in children and adolescents: A systematic review and meta-analysis

BACKGROUND

Group trauma-focused cognitive behavior therapy (TF-CBT) is widely used to treat post-traumatic stress disorder (PTSD) in children and adolescents. However, the available evidence remains unclear.

METHOD

PubMed, EMBASE, Cochrane, Web of Science, PsycINFO, CINAHL, ProQuest Dissertations, LILACS, and international trial registers were searched from database inception to April 30, 2022. We included randomized controlled trials (RCTs) that compared TF-CBT with any control condition for treating children and adolescents with PTSD. Analyses were performed using Review Manager version 5.3 and Stata 16.0. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. This study was registered with PROSPERO (CRD42020206096).

RESULTS

Eleven RCTs involving 1942 patients were included. Group TF-CBT was significantly more effective than other treatments at post-treatment (standardized mean difference [SMD]: -0.43, 95% confidence interval [CI]: -0.65 to -0.22), follow-up (SMD: -0.33, 95% CI: -0.52 to -0.13), and in relieving depressive symptoms (SMD: -0.29, 95% CI: -0.49 to -0.09), but not in terms of acceptability. Subgroup analyses showed that group TF-CBT was superior to other treatments in studies including children with post-traumatic stress symptoms (PTSS) (SMD: -0.54, 95% CI: -0.79 to -0.28) and psychiatric comorbidities (SMD: -0.48, 95% CI: -0.72 to -0.23).

LIMITATIONS

The small sample sizes of identified studies limited some findings.

CONCLUSION

When considering effectiveness at post-treatment and follow-up or the reduction of depressive symptoms, group TF-CBT could be a good choice for children and adolescents with PTSD. Among these patients, those with PTSS or psychiatric comorbidities may benefit the most.

Associations of Chronic Pain With Psychosocial Outcomes After Traumatic Brain Injury: A NIDILRR and VA TBI Model Systems Collaborative Project

OBJECTIVE

To examine the differences in participation, life satisfaction, and psychosocial outcomes among individuals with traumatic brain injury (TBI) endorsing current, past, or no chronic pain.

SETTING

Community.

PARTICIPANTS

Three thousand eight hundred four TBI Model Systems participants 1 to 30 years of age postinjury classified into 1 of 3 groups based on their pain experience: current pain, past pain, no pain completed a Pain Survey at their usual follow-up appointment which on average was approximately 8 years postinjury.

DESIGN

Multisite, cross-sectional observational cohort study.

MAIN OUTCOME MEASURES

Sociodemographic and injury characteristics and psychosocial outcomes (ie, satisfaction with life, depression, anxiety, posttraumatic stress disorder [PTSD], sleep quality, community participation).

RESULTS

Persons with current chronic pain demonstrated higher scores on measures of PTSD, anxiety, and depression, and the lower scores on measures of sleep quality, community participation and satisfaction with life. Those with resolved past pain had mean scores for these outcomes that were all between the current and no chronic pain groups, but always closest to the no pain group. After adjusting for sociodemographic and function in multivariate analysis, having current chronic pain was associated with more negative psychosocial outcomes. The largest effect sizes (ES; in absolute value) were observed for the PTSD, depression, anxiety, and sleep quality measures (ES = 0.52-0.81) when comparing current pain to past or no pain, smaller ES were observed for life satisfaction (ES = 0.22-0.37) and out and about participation (ES = 0.16-0.18). When comparing past and no pain groups, adjusted ES were generally small for life satisfaction, PTSD, depression, anxiety, and sleep quality (ES = 0.10-0.23) and minimal for participation outcomes (ES = 0.02-0.06).

CONCLUSIONS

Chronic pain is prevalent among individuals with TBI and is associated with poorer psychosocial outcomes, especially for PTSD, depression, anxiety, and sleep disturbance. The results from this study highlight the presence of modifiable comorbidities among those with chronic pain and TBI. Persons who experience persistent pain following TBI may be at greater risk for worse psychosocial outcomes.

The Psychedelic Future of Post-Traumatic Stress Disorder Treatment

Post-traumatic stress disorder (PTSD) is a mental health condition that can occur following exposure to a traumatic experience. An estimated 12 million U.S. adults are presently affected by this disorder. Current treatments include psychological therapies (e.g., exposure-based interventions) and pharmacological treatments (e.g., selective serotonin reuptake inhibitors (SSRIs)). However, a significant proportion of patients receiving standard-of-care therapies for PTSD remain symptomatic, and new approaches for this and other trauma-related mental health conditions are greatly needed. Psychedelic compounds that alter cognition, perception, and mood are currently being examined for their efficacy in treating PTSD despite their current status as Drug Enforcement Administration (DEA)- scheduled substances. Initial clinical trials have demonstrated the potential value of psychedelicassisted therapy to treat PTSD and other psychiatric disorders. In this comprehensive review, we summarize the state of the science of PTSD clinical care, including current treatments and their shortcomings. We review clinical studies of psychedelic interventions to treat PTSD, trauma-related disorders, and common comorbidities. The classic psychedelics psilocybin, lysergic acid diethylamide (LSD), and N,N-dimethyltryptamine (DMT) and DMT-containing ayahuasca, as well as the entactogen 3,4-methylenedioxymethamphetamine (MDMA) and the dissociative anesthetic ketamine, are reviewed. For each drug, we present the history of use, psychological and somatic effects, pharmacology, and safety profile. The rationale and proposed mechanisms for use in treating PTSD and traumarelated disorders are discussed. This review concludes with an in-depth consideration of future directions for the psychiatric applications of psychedelics to maximize therapeutic benefit and minimize risk in individuals and communities impacted by trauma-related conditions.

An 8-week compassion and mindfulness-based exposure therapy program improves posttraumatic stress symptoms

The persistence of posttraumatic stress symptoms (PTSS) can be debilitating. However, many people experiencing such symptoms may not qualify for or may not seek treatment. Potentially contributing to ongoing residual symptoms of PTSS is emotion dysregulation. Meanwhile, the research area of mindfulness and compassion has grown to imply emotion regulation as one of its underlying mechanisms; yet, its influence on emotion regulation in PTSS cohort is unknown. Here, we explored the potential effectiveness of an 8-week Compassion-oriented and Mindfulness-based Exposure Therapy (CoMET) for individuals with PTSS using a waitlist control design. A total of 28 individuals (27 females, age range = 18-39 years) participated in the study (17 CoMET; 11 waitlist control). Following CoMET, participants reported significant decreases in PTSS severity (from clinical to non-clinical levels), emotion dysregulation and experiential avoidance, as well as significant increases in mindfulness, self-compassion and quality of life. Electroencephalogram-based brain network connectivity analysis revealed an increase in alpha-band connectivity following CoMET in a network that includes the amygdala, suggesting that CoMET successfully induced changes in functional connectivity between brain regions that play a crucial role in emotion regulation. In sum, the current study demonstrated promising intervention outcomes of CoMET in effectively alleviating the symptoms of PTSS via enhanced emotion regulation.

Latent profiles of posttraumatic stress disorder symptoms and sleep disturbances in relation to drinking to cope motives among college students

BACKGROUND

Posttraumatic stress disorder (PTSD), sleep disturbances, and problematic alcohol use are frequently comorbid. Research shows that individuals with more PTSD symptom severity and poorer sleep are highly susceptible to drinking alcohol to cope with negative affect. The current study examined the number and nature of different subgroups of trauma-exposed college students based on endorsed PTSD symptoms and sleep disturbances; and how such subgroups relate to drinking to cope motives.

METHOD

The sample included 474 trauma-exposed college students (Mage = 20.69 years; 75.50% female) who completed self-report surveys.

RESULTS

Latent profile analyses revealed three subgroups: High PTSD-Sleep Disturbances (n = 71), Moderate PTSD-Sleep Disturbances (n = 135), and Low PTSD-Sleep Disturbances (n = 268). Results indicated that college students in the Low PTSD-Sleep Disturbances group endorsed the lowest amount of coping-related drinking motives; however, college students in the Moderate PTSD-Sleep Disturbances group did not endorse significantly different levels of coping-related drinking motives than college students in the High PTSD-Sleep Disturbances group.

CONCLUSIONS

College students with subclinical presentations of psychopathology are at risk for endorsing risky drinking motives. As they adjust to a stressful environment with a culture of heavy drinking, providing context-relevant intervention efforts such as adaptive coping strategies, relaxation skills designed to facilitate restful sleep, and trauma-informed care may be highly beneficial for college students.

Inhibitory control as possible risk and/or resilience factor for the development of trauma related symptoms-a study of the Utøya terror attack survivors

PTSD symptomatology is known to be associated with executive dysfunction. Inhibitory control is a core component of executive functioning, and inhibitory skills are essential both for adequate functioning in everyday life and important in situations following trauma. The aim of the present study was to examine the relationship between trauma exposure, inhibitory control and PTSD symptomatology in adolescent survivors of the terror attack at Utøya, Norway on the 22nd of July, 2011. In this cross-sectional case-control study, 20 trauma exposed adolescents and 20 healthy controls matched in age and gender were compared on a neuropsychological test of cognitive inhibition (Color-Word Interference Test) and a self-report measure of inhibition ability (BRIEF-A). Our analyses revealed that the trauma exposed group differed significantly on the self-reported measure of inhibitory control compared to the control group, but there were no differences between groups on the objective measures of cognitive inhibition. Follow-up analyses with subgroups in the trauma exposed group based on PTSD symptomatology (PTSD + and PTSD-) and the control group revealed that the PTSD- group showed significantly better results than both the PTSD + and the control group on the measures of inhibitory control. Moreover, the follow-up analyses showed that the PTSD + group showed significantly poorer results from the other two groups on the measures of inhibitory control and self-reported inhibition. We conclude that impaired inhibitory control, measured both objectively and by self-reported questionnaire, is related to PTSD symptomatology. Findings suggest that inhibitory dysfunctions may be a vulnerability factor for the development of PTSD symptomatology in trauma exposed adolescents, and thus it seems that the ability to exhibit inhibitory control could be a possible resilience factor to prevent the development of PTSD symptoms.

The main and interactive effects of distress tolerance and reward function on posttraumatic stress disorder symptoms among firefighters

BACKGROUND

Firefighters are at heightened risk of posttraumatic stress disorder (PTSD), underscoring the importance of understanding clinically targetable factors to inform evidence-based intervention development. Hedonic capacity, or the ability to experience pleasure, is a facet of reward functioning. Anhedonia (i.e., low or absent hedonic capacity) is a hallmark symptom of PTSD. Distress tolerance (DT), or the perceived ability to withstand negative emotional states, has also demonstrated associations with PTSD.

OBJECTIVE

The purpose of the present study was to examine the main and interactive effects of self-reported hedonic capacity (Snaith-Hamilton Pleasure Scale) and DT (Distress Tolerance Scale) on PTSD symptom severity among firefighters.

METHOD

A hierarchical linear regression was performed among a sample of 802 trauma-exposed career firefighters, who completed a battery of self-report questionnaires. Covariates included trauma load (i.e., number of trauma types), years in the fire service, and depression symptoms (excluding anhedonia).

RESULTS

Both hedonic capacity (B = 2.71, SE = .95, p = .005) and DT (B = -.21, SE = .03, p < .001) were incrementally associated with PTSD symptom severity. The interactive effect of hedonic capacity and DT was associated with heightened PTSD symptom severity (B = .25, SE = .07, p < .001).

CONCLUSIONS

Hedonic capacity and DT were independently and transactionally associated with heightened PTSD symptom severity among trauma-exposed firefighters. These findings provide evidence for the utility in developing interventions that target DT and impaired hedonic capacity among firefighters, particularly those experiencing PTSD symptomatology.

The Neurophysiology Behind Trauma-Focused Therapy Modalities Used to Treat Post-Traumatic Stress Disorder Across the Life Course: A Systematic Review

This review presents the current state of understanding of trauma-informed modalities in light of current research in neuroscience, analyzing which brain structures and processes are impacted by these modalities. Studies included in the present review met the inclusion criteria of 1) addressing post-traumatic stress disorder (PTSD) in a specific population, 2) treatment of PTSD using any of the evidence-based trauma-informed modalities considered in this review, and 3) presenting functional magnetic resonance imagery (fMRI) data, derived from BOLD signals and voxel-compression maps, of brain structures impacted by these trauma-informed modalities. Articles for this review were collated through PubMed and MEDLINE, using key terms in descending order, such as 'childhood trauma', 'adolescent trauma', and 'adulthood trauma', to 'PTSD', 'fMRI', and so on, depending on the modality in question. Based on these criteria and research methods, 37 studies remained for inclusion in the present review. Among a number of critical findings, this review demonstrates that eye movement desensitization and reprocessing (EMDR) and mindfulness therapy effectively deactivate hindbrain regions implicated in the downregulation of autonomic nervous system (ANS) hyperarousal. This review also shows that trauma-focused cognitive behavioral therapy (TF-CBT) and EMDR activate the hippocampus, anterior cingulate cortex (ACC), medial prefrontal cortex (mPFC), and orbitofrontal cortex (OFC)-areas that are implicated in crucial cognitive, affective, and behavioral processes that aid trauma survivors in navigating their challenges.

Four-symptom model of medical-related posttraumatic stress among adult cancer patients

OBJECTIVE

Four symptoms of posttraumatic stress (PTSS: intrusion, avoidance, alterations in arousal and reactivity, and negative alterations in cognitions and mood) were put forth by the Diagnostic and Statistical Manual of Mental Disorder (DSM-5). Patients with chronic major medical illness and their family caregivers often perceive the illness experience as traumatic, yet DSM-5 criteria precludes medical illness as a potential traumatic exposure. In this article, we address the applicability of the four symptoms to a medical population.

METHOD

Adult patients with colorectal cancer (n = 130, M = 55.83 years old, 60.0% female, 46.9% Hispanic) and their family caregivers (n = 160, M = 51.01 years old, 72.5% female, 49.0% Hispanic) completed questionnaires around the time of cancer diagnosis and treatment initiation (Time 1 [T1]), and 1- (Time 2 [T2]) and 2- (Time 3 [T3]) year postdiagnosis. Intrusion, avoidance, and alterations in arousal and reactivity symptoms were assessed using the Impact of Events Scale-Revised and negative alterations in cognitions and mood were quantified with selected conceptually congruent items from various psychosocial measures.

RESULTS

Confirmatory factor analysis revealed good fit of the four-symptom model of PTSS for caregivers at all three times and for patients at T2. Factor loadings of the four symptoms were high, ranging from .47-.97 and .62-.96 among patients and caregivers, respectively.

CONCLUSIONS

Findings extend the application of the four posttraumatic stress symptoms to patients with chronic major medical illness (cancer) and their family caregivers. Assessment and treatment of subclinical, yet substantial psychological distress precipitated by major medical illness like cancer are warranted.

Brain Responses to a Self-Compassion Induction in Trauma Survivors With and Without Post-traumatic Stress Disorder

Self-compassion (SC) is a mechanism of symptom improvement in post-traumatic stress disorder (PTSD), however, the underlying neurobiological processes are not well understood. High levels of self-compassion are associated with reduced activation of the threat response system. Physiological threat responses to trauma reminders and increased arousal are key symptoms which are maintained by negative appraisals of the self and self-blame. Moreover, PTSD has been consistently associated with functional changes implicated in the brain's saliency and the default mode networks. In this paper, we explore how trauma exposed individuals respond to a validated self-compassion exercise. We distinguish three groups using the PTSD checklist; those with full PTSD, those without PTSD, and those with subsyndromal PTSD. Subsyndromal PTSD is a clinically relevant subgroup in which individuals meet the criteria for reexperiencing along with one of either avoidance or hyperarousal. We use electroencephalography (EEG) alpha-asymmetry and EEG microstate analysis to characterize brain activity time series during the self-compassion exercise in the three groups. We contextualize our results with concurrently recorded autonomic measures of physiological arousal (heart rate and skin conductance), parasympathetic activation (heart rate variability) and self-reported changes in state mood and self-perception. We find that in all three groups directing self-compassion toward oneself activates the negative self and elicits a threat response during the SC exercise and that individuals with subsyndromal PTSD who have high levels of hyperarousal have the highest threat response. We find impaired activation of the EEG microstate associated with the saliency, attention and self-referential processing brain networks, distinguishes the three PTSD groups. Our findings provide evidence for potential neural biomarkers for quantitatively differentiating PTSD subgroups.

Indirect Associations Between Posttraumatic Stress Symptoms and Other Psychiatric Symptoms, Alcohol Use, and Well-being via Psychological Flexibility Among Police Officers

Police officers experience a high number of potentially traumatic events (PTEs) often associated with elevated posttraumatic stress symptoms (PTSS). In addition, PTSS are related to co-occurring psychiatric symptoms (e.g., anxiety, depression), alcohol misuse, and low perceived well-being. Yet, behavioral processes that may account for the associations between PTSS and unfavorable outcomes remain unspecified. Psychological flexibility, or one's response to private experiences (e.g., PTE-related memories) with an open, aware, and active approach, may be one such process. The present study aimed to evaluate psychological flexibility as both a mediator and moderator of PTSS and commonly co-occurring psychiatric symptoms, alcohol use, and general well-being, using cross-sectional data provided by a sample of police officers (N = 459) recruited from three regionally distributed U.S. police agencies. Structural equation modeling indicated a well-fitting model wherein psychological flexibility indirectly accounted for associations among PTSS and endogenous outcomes, χ² (107, N = 457) = 225.33, p < .001, CFI = .99, TLI = .98, RMSEA = .05, 90% CI [.04, .06], SRMR = .03. Psychological flexibility also moderated associations between PTSS and psychiatric symptoms, B = 1.58 (SE = 0.22), p < .001; and well-being, B = -3.84 (SE = 0.46), p < .001. Although additional research is needed, these preliminary results suggest psychological flexibility may be a behavioral process that accounts for negative outcomes associated with PTSS and a productive intervention target in the context of PTSS and generalized distress. Further research regarding the role of psychological flexibility in PTSS-related outcomes for police officers appears warranted.

Two-Step Resilience-Oriented Intervention for Veterans with Traumatic Brain Injury: A Pilot Randomized Controlled Trial

OBJECTIVE

The present randomized parallel two-arm pilot study aimed to compare the efficacy of two-step resilience-oriented intervention with treatment as usual in veterans with mild to moderate traumatic brain injury.

METHOD

Two-step Resilience-Oriented Intervention (TROI) is a brief psychological intervention that targets cognitive (step 1) and emotional (step 2) factors of resilience and consists of six 1-hour sessions. Overall, 70 Ukrainian veterans serviced in Anti-Terrorist Operation / Joint Forces Operation were randomly assigned to an intervention group (TROI group) or a control group that underwent treatment as usual (TAU group). For pre- (T1) and post-treatment (T2) assessment the Connor-Davidson Resilience Scale (CD-RISC), Hospital Anxiety and Depression Scale (HADS), Montreal Cognitive Assessment Scale (MoCA), Neurobehavioral Symptom Inventory (NSI), Posttraumatic Stress Disorder Checklist 5 (PCL-5), Chaban Quality of Life Scale (CQLS), Positive and Negative Affect Scale (PANAS) were used.

RESULTS

Multivariable linear regression with the treatment group, gender, baseline cognitive performance level and TBI severity as the independent variables revealed statistically significant improvements in the TROI group in resilience (CD-RISC), cognitive performance (MoCA), postconcussive symptoms (NSI), posttraumatic symptoms (PCL-5), positive affect (PANAS) and quality of life (CQLS) comparing to such in TAU group. We found no statistically significant differences between groups in depression, anxiety (HADS) and negative affect (PANAS) outcomes. Additionally, Wilcoxon signed-rank test revealed that participants who completed two-step resilience-oriented intervention had significantly improved scores for all outcomes compared to the baseline (p < 0.05).

CONCLUSIONS

In summary, we can tentatively conclude that adding TROI to the standard treatment measures may improve the resilience and sustainable symptoms in veterans with TBI when compared with standard treatment. Targeting cognitive and emotional factors like problem-solving, decision-making, positive thinking can promote resilience in veterans with TBI and be useful in facilitating recovery from injury. Results of this pilot study are promising, but the intervention needs to be studied in a larger trial.

[Skills fOr Life Adjustment and Resilience Program]

Hintergrund

Nach Katastrophen, Traumata und anderen schweren Belastungen entwickelt ein Teil der Betroffenen eine psychische Erkrankung, während ein weiterer Teil anhaltende subklinische Belastungen zeigt, die das psychosoziale Funktionsniveau einschränken. Anhaltend subklinisch belastete Menschen erhalten jedoch selten psychosoziale Unterstützungsangebote.

Ziel der Arbeit

Vorgestellt wird das Programm „Skills fOr Life Adjustment and Resilience“ (SOLAR), eine Kurzintervention für Menschen mit anhaltender subklinischer Belastung nach Katastrophen und anderen schweren Belastungen. Erste Ergebnisse einer Pilotstudie zur Zufriedenheit mit dem Programm bei Betroffenen werden berichtet.

Methoden

Das SOLAR-Programm wurde von einem internationalen Konsortium, zusammengesetzt aus Katastrophen- und Traumaexperten, entwickelt. Es beinhaltet 5 wöchentliche Gruppensitzungen, in denen verhaltenstherapeutische Elemente vermittelt werden. Im Rahmen der Pilotstudie nahmen 15 Teilnehmende im Präsenzformat und 15 Teilnehmende mithilfe einer Videokonferenzschaltung während der „Coronavirus Disease 2019“ (COVID-19) Pandemie am SOLAR Programm teil. Nach Abschluss beantworteten die Teilnehmenden den Fragebogen zur Messung der Patientenzufriedenheit (ZUF-8).

Ergebnisse

Die Teilnehmenden waren „weitgehend“ bis „sehr zufrieden“. In der Präsenzgruppe war die Zufriedenheit über alle Aspekte hinweg geringfügig stärker ausgeprägt als in der Onlinegruppe. Die TrainerInnen bewerteten das Programm als gut durchführbar.

Schlussfolgerung

Das SOLAR-Programm ist eine vielversprechende Kurzintervention bei anhaltender subklinischer Belastung nach schweren Belastungen, die im Präsenz- oder im videogestützten Format weiter auf seine Wirksamkeit erprobt werden sollte. Im Beitrag werden Praxisempfehlungen zur Durchführung gegeben.

Vulnerability to COVID-19-Related Disability: The Impact of Posttraumatic Stress Symptoms on Psychosocial Impairment During the Pandemic

As a result of the COVID-19 pandemic, many individuals have experienced disruptions in social, occupational, and daily life activities. Individuals with mental health difficulties, particularly those with elevated posttraumatic stress symptoms (PTSS), may be especially vulnerable to increased impairment as a result of COVID-19. Additionally, demographic factors, such as age, gender, and race/ethnicity, may impact individual difficulties related to the pandemic. The current study examined the concurrent and prospective associations between posttraumatic stress disorder (PTSD) symptoms, broader anxiety and depression symptoms, and COVID-19-related disability. Participants recruited through Amazon's Mechanical Turk (N = 136) completed questionnaire batteries approximately 1 month apart during the COVID-19 pandemic (i.e., Wave 1 and Wave 2). The results indicated that PTSD, anxiety, and depressive symptoms were all associated with increased COVID-19-related disability across assessment points, rs = .44-.68. PTSD symptoms, specifically negative alterations in cognition and mood, significantly predicted COVID-19-related disability after accounting for anxiety and depressive symptoms as well as demographic factors, βs = .31-.38. Overall, these findings suggest that individuals experiencing elevated PTSS are particularly vulnerable to increased functional impairment as a result of COVID-19 and suggest a need for additional outreach and clinical care among individuals with elevated PTSD symptoms during the pandemic.

Response-to-Treatment for Comorbid Post-Traumatic Stress and Substance Use Disorders: The Value of Combining Person- and Variable-Centered Approaches

Optimizing treatment for co-occurring post-traumatic stress disorder and substance use disorder (PTSD+SUD) is critically important. Whereas treatments have been designed that target PTSD+SUD with some success, these treatments do not benefit all. Data-driven approaches that combine person- and variable-centered methods, such as parallel process latent class growth analysis (PP-LCGA) can be used to identify response-to-treatment trajectories across both PTSD symptoms and substance use. The current study employed PP-LCGA separately in two randomized clinical trials (study 1 n = 81, Mean age = 40.4 years, SD = 10.7; study 2 n = 59, Mean age = 44.7 years, SD = 9.4) to examine PTSD symptom response and percentage of days using substances across treatment trials comparing Concurrent Treatment of PTSD and SUD using Prolonged Exposure and Relapse Prevention. Results revealed four PTSD+SUD profiles for study one and three PTSD+SUD profiles for study two. For PTSD symptoms, response trajectories could be broadly classified into treatment responders and non-responders across both studies. For substance use, response trajectories could be broadly classified into declining, moderately stable, and abstaining profiles. When considering PTSD symptoms and substance use trajectories together, profiles emerged that would have been missed had these treatment outcomes been considered separately.

Psychological trauma in different mechanisms of traumatic injury: A hospital-based cross-sectional study

Background

Psychological distress following traumatic injury can influence the patient health, well-being and quality of life; however, this impact may partly vary according to the type and severity of injury. We aimed to study the predominant distress causing cluster and individual symptoms of Post-Traumatic Stress Disorders (PTSD) at the clinical and subthreshold level in patients with traumatic injuries, based on the mechanism of injury (MOI).

Methods

A hospital based cross-sectional study was conducted at a Level 1 Trauma Center utilizing PTSD Checklist to diagnose PTSD after one month of the traumatic event. All patients suffering from psychological distresses were assessed by a clinical psychologist in the trauma section. PTSD diagnostic criteria from DSM-5 were used to classify the patients. The inclusion criteria comprised of adult trauma patients who were directly involved in traumatic injuries and admitted under the Trauma Surgery services for a minimum of one day; have ability to provide written informed consent and can be assessed with the PCL-5 checklist after 4 weeks post-injury.

Results

Two hundred patients completed PCL-5 checklist, of them 26 (13.0%) were positive for PTSD and 174 (87%) had subthreshold scores. The mean age of participants was 34.4±11.8 years and males constituted 90.5%. Road traffic injury (RTI) was most the frequent injury mechanism (59%). PTSD positive patients with RTI, fall of heavy objects, pedestrian injury and assaults had highest average scores on clusters of negative alterations in mood and cognitions (16.9, 18.0, 18.5, 17.0 respectively), followed by hyperarousal. Symptom of always being on the guard and having repeated unwanted or disturbing memories of the incident, was reported by nearly 100% PTSD positive patients. Patients with subthreshold scores also reported distressing symptoms on all four clusters of PTSD.

Conclusions

Patients with different MOI showed a broad range of psychological problems with respect to symptom clusters. Negative alteration in mood and cognition followed by hyperarousal caused higher level of distress in patients post traumatic injuries. Subthreshold symptoms of PTSD are more common and deserve more attention.

Sex differences in the association between PTSD symptoms with cardiac autonomic function and subclinical atherosclerotic risk

BACKGROUND

Post-traumatic stress disorder (PTSD) is a public health concern that may elevate the risk for cardiovascular disease (CVD). There are established sex differences in both PTSD risk and CVD risk.

PURPOSE

To examine sex-specific associations between subclinical PTSD symptom severity and subclinical CVD risk in young men and women.

METHODS

A total of 61 young adults (women: n = 29, mean age: 26 ± 7 years) completed the post-traumatic stress disorder civilian checklist (PCL) and the Center for Epidemiologic Studies Depression Scale (CES-D). Aortic stiffness was measured as carotid-femoral pulse wave velocity (cfPWV). Peripheral vasomotor function was measured as flow-mediated slowing (FMS) of carotid-radial PWV following 5-min forearm occlusion. Heart rate variability was used to assess sympathovagal balance as LF/HF ratio.

RESULTS

PCL score was positively correlated with CES-D score (r = 0.79, p < .001), cfPWV (r = 0.33, p = .03) and LF/HF ratio (r = 0.42, p = .009) in men. PCL score was positively correlated to CES-D score (r = 0.80, p < .001) in women, but was inversely correlated to cfPWV (r = -0.38, p = .02) and LF/HF ratio (r = -0.34, p = .04). PCL score was also inversely associated with FMS in women (r = -0.49, p = .01).

CONCLUSION

There are sex differences in the association of PTSD symptoms and subclinical atherosclerosis. In men, increased PTSD symptoms may increase CVD risk by increasing sympathovagal balance and aortic stiffness. In women, increased PTSD symptoms may increase CVD risk via reducing vasomotor function.

Pilot of a screening, brief intervention and referral to treatment process for symptoms of trauma among primary care patients

BACKGROUND

For populations with high rates of trauma exposure yet low behavioural health service use, identifying and addressing trauma in the primary care setting could improve health outcomes, reduce disability and increase the efficiency of health system resources.

OBJECTIVE

To assess the acceptability and feasibility of a screening, brief intervention and referral to treatment (SBIRT) process for trauma and symptoms of posttraumatic stress disorder (PTSD) among American Indian and Alaska Native people. We also examine the short-term effects on service utilization and the screening accuracy of the Primary Care Posttraumatic Stress Disorder Screen.

METHODS

Cross-sectional pilot in two tribal primary care settings. Surveys and interviews measured acceptability among patients and providers. Health service utilization was used to examine impact. Structured clinical interview and a functional disability measure were used to assess screening accuracy.

RESULTS

Over 90% of patient participants (N = 99) reported the screening time was acceptable, the questions were easily understood, the right staff were involved and the process satisfactory. Ninety-nine percent would recommend the process. Participants screening positive had higher behavioural health utilization in the 3 months after the process than those screening negative. The Primary Care Posttraumatic Stress Disorder Screen was 100% sensitive to detect current PTSD with 51% specificity. Providers and administrators reported satisfaction with the process.

CONCLUSIONS

The SBIRT process shows promise for identifying and addressing trauma in primary care settings. Future research should explore site specific factors, cost analyses and utility compared to other behavioural health screenings.

Sub-syndromal PTSD: what is important to know in military personnel and veterans?

OBJECTIVE

To assist healthcare professionals in their management of military personnel and veterans by providing information on the importance of sub-syndromal PTSD.

CONCLUSION

Sub-syndromal PTSD occurs when persons experience many of the symptoms of PTSD, with some impairment, but do not meet full diagnostic criteria. Found to be associated with a range of mental health conditions including alcohol abuse, higher rates of suicidal ideas and delayed-onset PTSD, it should be seen as 'symptoms that are predictive of later disorder'. Patients with this condition need accurate assessment, trauma-focused therapy and follow-up to address the symptoms and, potentially, prevent development of PTSD.

Adaptive Information Processing Theory: Origins, Principles, Applications, and Evidence

This paper describes the origins, principles, applications, and evidence related to Adaptive Information Processing (AIP) theory. AIP theory provides the theoretical underpinning of Eye Movement Desensitization and Reprocessing (EMDR) therapy. AIP theory was developed to explain the observed results of EMDR therapy delivered to individuals experiencing trauma and PTSD. The AIP model hypothesizes that maladaptively stored memories of trauma create obstacles to rational processing of information, which occurs in the prefrontal cortex area of the brain. Bilateral stimulation, through eye movements or other mechanisms, is hypothesized to remove the obstacles and permit complete processing of the memory, leading to a reduction in trauma symptoms. EMDR therapy, with the AIP model as rationale, has been effectively used in the treatment of PTSD. Evidence in support of AIP theory is emerging as some promising results have been shown in studies that rely on measuring various types of physiological changes that occur during EMDR therapy.

Resolution of Dissociated Ego States Relieves Flashback-Related Symptoms in Combat-Related PTSD: A Brief Mindfulness Based Intervention

A novel understanding and therapeutic approach to the treatment of PTSD-related flashback triggers are described. Triggered responses are conceptualized as the result of latent dissociative structures of neural organization and psychodynamic functioning activated by current events. The dissociative structure - here described as a dissociated ego state (DES) - reflects a fracturing of executive functioning resulting in a delimited aspect of self that is not under cognitive control or subject to cognitive inhibition by the self of daily experience, and is the psychological construct behind intrusive PTSD symptoms. Use of a mindful attentional state permits regulated access to the DES (therapeutic engagement without risk of emotional dysregulation) so that dissociated cognitive resources can be recovered and the dissociated structure deactivated. This may relieve maladaptive responses and behaviors associated with the DES in a profound and durable way, without the need for exposure to or recovery of traumatic memories. Based on this understanding, a 9-step intervention is introduced with a case example of a Vietnam veteran suffering PTSD symptoms for 49 years with significant gains maintained at 21 months follow up. These findings demonstrate rapid and durable resolution of chronic PTSD symptoms through a mindfulness-based approach that focused on deactivation of dissociated ego states, in contrast to targeting trauma memories. If proven efficacious, this novel approach may result in reduced treatment costs and improved outcomes for veterans suffering with PTSD.

Efficacy of Self-Management Smartphone-Based Apps for Post-traumatic Stress Disorder Symptoms: A Systematic Review and Meta-Analysis

Post-traumatic stress disorder (PTSD) symptoms are prevalent in both civilian and military service members. As the number of smartphone-based applications (apps) grows rapidly in health care, apps are also increasingly used to help individuals with subthreshold PTSD or full PTSD. Yet, if the apps are self-managed, the feasibility and efficacy of such interventions are still rather unclear in these two populations with PTSD symptoms. Hence, the present meta-analysis set out to evaluate the effect of self-management smartphone-based apps on PTSD and depressive symptoms in populations with subthreshold PTSD or full PTSD. Studies were included if they conducted randomized controlled trials or pre-post comparisons. Six studies (n = 2 randomized controlled trials) were identified for meta-analysis. In pre-post comparisons, N = 209 participants were included in the analyses. In randomized controlled trials, N = 87 participants received smartphone-based self-management interventions and N = 82 participants were in waitlist control conditions. Meta-analysis for pre-post comparisons concluded an effect of g = 0.55 (p < 0.001) regarding the overall reduction in PTSD symptoms (n = 6) and g = 0.45 (p < 0.001) for reduction in depressive symptoms (n = 5). Yet, in randomized controlled trials, no significant difference was found between app-based treatment and waitlist control groups (g = 0.09, p = 0.574). The duration of the interventions did not significantly influence the results. Overall, despite positive pre-post effects, current results indicate that smartphone-apps for PTSD patients are not significantly more effective than waitlist control conditions. Nevertheless, a combined smartphone and standard therapy approach may be a fruitful field for future research.

Investigating Individual Pre-trauma Susceptibility to a PTSD-Like Phenotype in Animals

Post-Traumatic Stress Disorder (PTSD) is a complex condition that develops after experiencing a severe emotional trauma, with or without physical trauma. There is no known cure and evidence-based treatments, which are effective in reducing symptoms, have low retention rates. It is therefore important, in addition to seeking new therapeutics, to identify ways to reduce the likelihood of developing PTSD. The fact that some, but not all, individuals exposed to the same traumatic event develop PTSD suggests that there is individual susceptibility. Investigating susceptibility and underlying factors will be better guided if there is a coherent framework for such investigations. In this review, we propose that susceptibility is a dynamic state that is comprised of susceptibility factors (before trauma) and sequalae factors (during or after trauma, but before PTSD diagnosis). We define key features of susceptibility and sequalae factors as: (1) they are detectable before trauma (susceptibility factors) or during/shortly after trauma (sequalae factors), (2) they can be manipulated, and (3) manipulation of these factors alters the likelihood of developing PTSD, thus affecting resilience. In this review we stress the importance of investigating susceptibility to PTSD with appropriate animal models, because prospective human studies are expensive and manipulation of susceptibility and sequalae factors for study purposes may not always be feasible. This review also provides a brief overview of a subset of animal models that study PTSD-related behaviors and related alterations in endocrine and brain systems that focus on individual differences, peri- and post-trauma. Attention is drawn to the RISP model (Revealing Individual Susceptibility to a PTSD-like Phenotype) which assesses susceptibility before trauma. Using the RISP model and expression of plasticity-associated immediate early genes, Arc and Homer1a, we have identified impaired hippocampal function as a potential susceptibility factor. We further discuss other putative susceptibility factors and approaches to mitigate them. We assert that this knowledge will guide successful strategies for interventions before, during or shortly after trauma that can decrease the probability of developing PTSD.

Direct and indirect psychological impacts of shark-bite events

OBJECTIVE

Shark bites are rare, with intense media exposure. There are no known studies of the psychological impacts of this specific type of traumatic event. This is the first study that describes those directly and indirectly affected, and evaluates the prevalence of post-traumatic stress disorder (PTSD) and related risk factors.

METHODS

In total, 124 members of an Australian shark-bite peer-support group were invited to complete an online survey assessing demographic, event, media and psychological factors. Response rate was 48% ( n = 60, 63% male, 44 ± 14 years). Retrospective and current measures of PTSD (PTSD Checklist for DSM-5 [PCL-5]) and suicidality (Suicidal Ideation Attributes Scale [SIDAS-5]) were used.

RESULTS

Post-event PTSD was prevalent in this sample ( n = 16/59, 27.1%, 95% confidence interval [CI] = [15.4, 38.8]), but less so currently ( n = 2/55, 3.6%, 95% CI = [0.0, 8.7]). In addition, nine ( n = 9/59, 15.3%, 95% CI = [5.8, 24.7]) had subthreshold, but highly symptomatic, syndromes post event. There was no association of PTSD with direct/indirect bite involvement, gender, or prior trauma. Two respondents were at risk of suicidal behaviour. PTSD was commonly reported by those without a partner (odds ratio [OR] = 5.91, 95% CI = [1.52, 22.99], p = 0.01) or with two friends or fewer to rely on (OR = 5.83, 95% CI = [1.62, 21.01], p = 0.01). PTSD was more likely in those with a negative media experience ( n = 34/52, 65.4%, OR = 11.90, 95% CI = [1.42, 100.04], p = 0.02) and 61.5% ( n = 32/52) of respondents reported media coverage lasting months or years. In multivariate modelling, negative media impact, relationship status and friendships were independently associated with PTSD and explained much of the variance in PTSD ( F_4,41 = 10.94, p < 0.0001, r² = 0.52).

CONCLUSION

Nearly one-third of members of an Australian shark-bite peer-support group report post-event PTSD, and one-quarter of these were not present at the time of the event. Findings support interventions targeting negative media impact, similar to media reporting guidelines for suicide, and enhancing social support.
