A Two-Phased Telehealth Model to Treat Post-Traumatic Stress Disorder in a Health Care Worker due to the COVID-19 Pandemic: A Case Report.

Background: We report a case describing the use of a two-step telehealth intervention to treat symptoms of post-traumatic stress disorder (PTSD) that developed in a frontline health care worker (HCW) during the COVID-19 pandemic. HCWs are at increased risk of adverse psychological outcomes, including PTSD, due to the nature of their work, which has been exacerbated by the global pandemic. Methods: This case represents the first successfully completed participant in a larger ongoing trial to address psychological distress, PTSD, and comorbidities in HCWs consequent to the COVID-19 pandemic. Following a two-step intervention of self-directed narrative writing delivered entirely online followed by prolonged exposure therapy using videoconferencing, the HCW displayed significant improvement in symptoms of PTSD, depression, anxiety, and substance use. Results: The treatment model described here offers preliminary support for a two-step remote delivery approach to meet the need for scalable self-directed distance technology-based mental health interventions for HCWs. This study is registered on clinicaltrials.gov (NCT04626050).

Predictors of involuntary and voluntary emotional episodic memories of virtual reality scenarios in Veterans with and without PTSD.

This study investigated predictors of involuntary and voluntary memories of stressful virtual reality scenarios. Thirty-two veterans of the two Persian Gulf Wars completed verbal memory tests and diagnostic assessments. They were randomly assigned to a Recounting (16) or a Suppression (16) condition. After immersion in the VR scenarios, the Recounting group described the scenarios and the Suppression group suppressed thoughts of the scenarios. One week later, participants completed surprise voluntary memory tests and another thought suppression task. The best predictors of voluntary memory were verbal memory ability, dissociation, and to a lesser extent, physiological arousal before and after scenarios. Dissociation and physiological stress responses selectively affected memory for neutral elements. Higher distress during scenarios impaired voluntary memory but increased the frequency of involuntary memories. Physiological stress responses promoted more frequent involuntary memories immediately after the scenarios. More frequent initial involuntary memories, tonic physiological arousal, and stronger emotional responses to dangerous events predicted difficulty inhibiting involuntary memories at follow-up. The effects of thought suppression were transient and weaker than those of other variables. The findings suggest that posttraumatic amnesia and involuntary memories of adverse events are more related to memory ability and emotional and physiological stress responses than to post-exposure suppression.

Virtual reality exposure versus prolonged exposure for PTSD: Which treatment for whom?

BACKGROUND: The majority of studies comparing active psychological treatments for posttraumatic stress disorder (PTSD) do not find significant differences at posttreatment. This was the case in a recent trial examining prolonged exposure (PE) and virtual reality exposure (VRE) among active-duty soldiers with combat-related PTSD. Matching individual patients to specific treatments provides a potential avenue to improve significantly the public health impact of effective treatments for PTSD. A composite moderator approach was used to identify profiles of patients who would see superior PTSD symptom reduction in VRE or PE to inform future treatment matching. METHODS: Active duty U.S. army soldiers (N = 108) were enrolled in a randomized clinical trial comparing VRE and PE in the treatment of PTSD stemming from deployments to Iraq or Afghanistan. Eighteen baseline variables were examined to identify treatment response heterogeneity in two patient groups: those with a superior response to PE and those with a superior response to VRE. The final composite moderator comprised four of 18 baseline variables. RESULTS: Results revealed that patients who were predicted to see greater PTSD symptom reduction in VRE were likely to be younger, not taking antidepressant medication, had greater PTSD hyperarousal symptoms, and were more likely to have greater than minimal suicide risk. CONCLUSIONS: Results suggest that treatment matching based on patient profiles could meaningfully improve treatment efficacy for combat-related PTSD. Future research can build on these results to improve our understanding of how to improve treatment matching for PTSD.

Posttraumatic Stress Disorder, Functional Impairment, and Subjective Distress in World Trade Center Disaster Workers.

Posttraumatic stress disorder (PTSD) is associated with functional deficits, poor physical health, and diminished quality of life. Limited research has examined PTSD symptom clusters and their associations with functioning and distress among disaster recovery workers, a population at high risk for PTSD due to potential for repeated trauma. The purpose of this study was to investigate associations between overall PTSD severity, as well as PTSD symptom clusters, and social and occupational functioning and subjective distress in World Trade Center (WTC) disaster workers after the terrorist attacks on September 11, 2001 (9/11). Disaster workers deployed to the site of the attacks completed assessments at three time points over approximately 5 years post-9/11. Our sample consisted of participants who met criteria for PTSD or subthreshold PTSD at baseline (n = 514), 1-year (n = 289), and 2-year follow-up (n = 179). Adjusted linear regression indicated that Clinician Administered PTSD Scale (CAPS)-rated PTSD severity was positively associated with subjective distress, and deficits in social and occupational functioning, over time, CAPS Criterion F items; ßs = .20 to .62, ps < .001. The reexperiencing and avoidance/numbing symptom clusters were associated with increased subjective distress, the avoidance/numbing and hyperarousal clusters were associated with deficits in social functioning, and the reexperiencing and hyperarousal clusters were associated with worse occupational functioning. These associations were consistent across the study period. Findings point to the importance of targeting PTSD symptom clusters associated with specific areas of functional impairment, with the goal of improving global outcomes.

Pilot Study of a Telehealth-Delivered Medication-Augmented Exposure Therapy Protocol for PTSD.

Posttraumatic stress disorder (PTSD) is a serious condition, with certain occupations at increased risk due to greater trauma exposure. These same individuals face multiple barriers to care. This study aimed to investigate the feasibility of conducting a research trial with exposure therapy delivered via videoconferencing. Eleven adults working in occupations at risk with PTSD enrolled and seven completed 12 to 15 sessions. Individuals were randomized to receive the cognitive enhancer D-cycloserine or placebo, and participants provided saliva samples for genetic analysis. Treatment completers demonstrated decreases in PTSD and depressive symptomatology (measured by CAPS [p < 0.001, d = 2.79] and BDI-II [p = 0.004, d = 0.92]). Participants reported high therapeutic alliance, treatment satisfaction, and telehealth satisfaction. There were no significant technical, medication, or safety issues, and no clinical emergencies. The results suggest that it may be feasible to conduct clinical research using telehealth for PTSD and to use telehealth to increase access to care.

Systematic Review of the Clinical Application of Exposure Techniques to Community-Dwelling Older Adults with Anxiety.

OBJECTIVES: Although exposure techniques are a first-line intervention for anxiety, clear evidence is lacking for their efficacy in treating the prevalent and debilitating condition of late life anxiety. This study sought to review the current literature on use of exposure with community-dwelling older patients. METHODS: Searches of electronic databases were conducted to identify articles published through December 7, 2016. Inclusion criteria were: 1) sample age > 55, 2) therapy that included exposure, 3) anxiety as a target of the treatment. Exclusion criteria were: 1) not available in English, 2) no quantitative data, 3) inpatient setting. Methodological data and findings were extracted from the articles chosen for review. RESULTS: The 54 eligible articles presented a total of 16 case studies, 9 uncontrolled trials, 24 controlled trials, and 6 secondary studies. A majority of the studies were conducted in the U.S.A with participants who received individual treatment. In vivo and imaginal exposure were the most frequently delivered techniques, and most treatments were multicomponent. Most studies found a reduction in anxiety symptoms. CONCLUSIONS: Important research gaps need to be addressed. CLINICAL IMPLICATIONS: The surveyed research provides a modest foundation of evidence for mental health practitioners who wish to incorporate exposure into treatment plans.

Evidence-based treatment of post-traumatic stress disorder.

The term translational research is typically used to refer both to "bench to bedside" research, in which preclinical research findings inform the development of novel therapeutics, and to the dissemination of new treatments to the community to encourage the use of the new health practices and treatments. Both definitions are germane to understanding the evidence base for treatment of post-traumatic stress disorder (PTSD) today. This article offers (a) an overview of evidence-based treatments for PTSD, (b) a description of a translational model of PTSD, and (c) a discussion of common barriers to dissemination and implementation of the empirically validated treatments. Recent studies in the field are discussed with a focus on pharmacotherapies, psychotherapies, and combined treatments.

Sleep disturbance, disability, and posttraumatic stress disorder in utility workers.

OBJECTIVE: The objective of the present study was to examine the associations between sleep disturbance, posttraumatic stress disorder (PTSD), and functional disability in a population exposed to a singular traumatic event. METHOD: The participants were a population of 2,453 predominantly male utility workers who were deployed to the World Trade Center site in the aftermath of the 9/11 attack. They underwent psychiatric screenings comprising measures of sleep disturbance, PTSD, and functional disability. RESULTS: Analyses indicated that (a) rates of sleep disturbances were significantly higher among participants diagnosed with PTSD than those without, (b) PTSD severity was significantly associated with sleep disturbance, and (c) sleep disturbance moderated the relationship between PTSD and disability. CONCLUSION: Sleep disturbance is associated with occupational, social functioning, and PTSD severity, suggesting that ameliorating sleep may lead to increased occupational and social functioning, as well as better treatment responses in PTSD.

Exposure-Based CBT for Older Adults After Fall Injury: Description of a Manualized, Time-Limited Intervention for Anxiety.

Fall accidents among older adults can be devastating events that, in addition to their physical consequences, lead to disabling anxiety warranting the attention of mental health practitioners. This article presents "Back on My Feet," an exposure-based cognitive-behavioral therapy (CBT) protocol that is designed for older adults with posttraumatic stress disorder (PTSD), subthreshold PTSD, or fear of falling resulting from a traumatic fall. The protocol can be integrated into care once patients have been discharged from hospital or rehabilitation settings back to the community. Following a brief description of its development, the article presents a detailed account of the protocol, including patient evaluation and the components of the eight home-based sessions. The protocol addresses core symptoms of avoidance, physiological arousal/anxiety, and maladaptive thought patterns. Because older patients face different coping challenges from younger patients (for whom the majority of evidence-based CBT interventions have been developed), the discussion ends with limitations and special considerations for working with older, injured patients. The article offers a blueprint for mental health practitioners to address the needs of patients who may present with fall-related anxiety in primary care and other medical settings. Readers who wish to develop their expertise further can consult the online appendices, which include a clinician manual and patient workbook, as well as guidance on additional resources.

Omission and Commission in Morally Injurious Experiences Among COVID-19 Health Care Professionals.

Objective: To produce a qualitative description of the impact of moral injury on medical providers during the COVID-19 pandemic.Methods: A convergent mixed-methods study design was used to explore experiences of health care workers during the first 12 months of the COVID-19 pandemic. Participants completed the Moral Injury Symptom Scale-HP (MISS-HP) and a 60-minute interview, in which they described their work experiences from March 2020 through January 2021. The study was conducted between May 2021 and August 2021.Results: Eight physicians and 6 nurses were interviewed. Most participants (71%) worked in the emergency department, while 29% worked in the medical intensive care unit (MICU). MISS-HP scores were 49 on average and ranged from 29 to 73. Among the demographic groups, MICU participants scored the highest (56) and men scored the lowest (40). There were no significant differences in scores between any demographic group. The analysis of interview data showed how omissions and commissions in one's professional duties created internal conflicts, which were inextricably linked to a deeper sense of feelings of guilt and blame around experiences of betraying or being betrayed and an inability to uphold one's moral values.Conclusions: The pandemic upended a previously reliable and imperceptible experience of a background of safety, in which the provision of both material resources and human presence was expected without question. Future directions generated from this study might examine the role of dependency on leadership structures and relationships with self and others that create the conditions for moral injury.Prim Care Companion CNS Disord 2024;26(1):23m03651.

Bringing mental health to the frontlines: A proactive team-based model for healthcare workers during the COVID-19 pandemic.

OBJECTIVE: A novel team-based service was developed at the beginning of the pandemic in which sixty liaisons were assigned to provide proactive, tailored psychological support for healthcare workers (HCWs) across three of NewYork-Presbyterian's Weill Cornell affiliated hospitals. METHOD: The program took the proactive approach of bringing mental health awareness to every department and major division that interfaced with COVID-19 patients. Virtual and in-person team-based "town hall" meetings were offered to provide psychoeducation, facilitate discussion, foster adaptive coping and social cohesion, and identify employees who would benefit from further individualized support. RESULTS: The program's success was reflected in the number of town halls (1000+) and attendees (6000+) and in qualitative feedback from departments who requested ongoing services. CONCLUSIONS: This article presents the development, implementation, challenges, and opportunities in designing a team-based support model for HCWs. This model may be useful for organizations that seek to develop similar programs.

A proof-of-concept randomized crossover clinical trial of a first-in-class vasopressin 1a receptor antagonist for PTSD: Design, methods, and recruitment.

Background: Almost eight million Americans suffer from Posttraumatic Stress Disorder (PTSD). Current PTSD drug therapies rely on repurposed antidepressants and anxiolytics, which produce undesirable side effects and have recognized compliance issues. Vasopressin represents a promising and novel target for pharmacological intervention. Logistical issues implementing a clinical trial for a novel PTSD pharmaceutical are relatively uncharted territory as trials concerning a new agent have not been published in the past several decades. All published trials have repurposed FDA-approved psychoactive medications with known risk profiles. Our recruitment challenges are discussed in this context. Methods: An 18-week proof-of-concept randomized crossover clinical trial of a first-in-class vasopressin 1a receptor antagonist (SRX246) for PTSD was conducted. All participants received SRX246 for 8 weeks, the placebo for 8 weeks, and the drug vs. placebo arms were compared. Participants were assessed every 2 weeks for PTSD symptoms as well as other medication effects. Results were expected to provide an initial demonstration of safety and tolerability in this clinical population and potentially clinical efficacy in SRX246-treated patients measured by Clinician Administered PTSD Scale (CAPS) score changes, clinical impression, and other indices compared to placebo. The primary hypothesis was that SRX246 would result in a clinically meaningful 10-point reduction in mean CAPS score compared to placebo. Discussion: This study is the first to investigate an oral vasopressin 1a receptor antagonist for PTSD. As a wave of PTSD clinical trials with new pharmaceutical compounds are beginning now, lessons learned from our recruitment challenges may be invaluable to these endeavors.

Development and testing of virtual reality exposure therapy for post-traumatic stress disorder in active duty service members who served in Iraq and Afghanistan.

This study was an open-label, single-group, treatment-development project aimed at developing and testing a method for applying virtual reality exposure therapy (VRET) to active duty service members diagnosed with combat post-traumatic stress disorder (PTSD). Forty-two service members with PTSD were enrolled, and 20 participants completed treatment. The PTSD Checklist-Military version, Patient Health Questionnaire-9 for depression, and the Beck Anxiety Inventory were used as outcome measures. Of those who completed post-treatment assessment, 75% had experienced at least a 50% reduction in PTSD symptoms and no longer met DSM-IV criteria for PTSD at post treatment. Average PSTD scores decreased by 50.4%, depression scores by 46.6%, and anxiety scores by 36%. Intention-to-treat analyses showed that statistically significant improvements in PTSD, depression, and anxiety occurred over the course of treatment and were maintained at follow up. There were no adverse events associated with VRET treatment. This study provides preliminary support for the use of VRET in combat-related PTSD. Further study will be needed to determine the wider utility of the method and to determine if it offers advantages over other established PTSD treatment modalities.

Enhancing exposure therapy for posttraumatic stress disorder (PTSD): a randomized clinical trial of virtual reality and imaginal exposure with a cognitive enhancer.

Posttraumatic stress disorder (PTSD) is a significant public health issue. Yet, there are limited treatment options and no data to suggest which treatment will work for whom. We tested the efficacy of virtual reality exposure (VRE) or prolonged imaginal exposure (PE), augmented with D-cycloserine (DCS) for combat-related PTSD. As an exploratory aim, we examined whether brain-derived neurotrophic factor (BDNF) and fatty acid amide hydrolase (FAAH) moderated treatment response. Military personnel with PTSD (n = 192) were recruited into a multisite double-blind randomized controlled trial to receive nine weeks of VRE or PE, with DCS or placebo. Primary outcome was the improvement in symptom severity. Randomization was stratified by comorbid depression (MDD) and site. Participants in both VRE and PE showed similar meaningful clinical improvement with no difference between the treatment groups. A significant interaction (p = 0.45) suggested VRE was more effective for depressed participants (CAPS difference M = 3.51 [95% CI 1.17-5.86], p = 0.004, ES = 0.14) while PE was more effective for nondepressed participants (M = -8.87 [95% CI -11.33 to -6.40], p < 0.001, ES = -0.44). The main effect of DCS vs. placebo was not significant. Augmentation by MDD interaction (p = 0.073) suggested that depressed participants improved more on placebo (M = -8.43 [95% CI -10.98 to -5.88], p < 0.001, ES = -0.42); DCS and placebo were equally effective for nondepressed participants. There was an apparent moderating effect of BDNF Val66Met polymorphism on DCS augmentation (ES = 0.67). Met66 allele carriers improved more on DCS (ES = -0.25). FAAH 385 A carriers improved more than non-carriers (ES = 0.33), particularly those with MDD (ES = 0.62). This study provides a step toward precision therapeutics for PTSD by demonstrating that comorbid MDD and genetic markers may help guide treatment selection.ClinicalTrials.gov Identifier: NCT01352637.

Prevalence and predictors of posttraumatic stress symptoms in utility workers deployed to the World Trade Center following the attacks of September 11, 2001.

BACKGROUND: Recent attention has begun to be focused on the effects of disaster recovery work on nonrescue workers. The goal of this study was to assess the prevalence and predictors of posttraumatic stress disorder (PTSD) and related symptoms in a population of utility workers deployed to the World Trade Center (WTC) site in the aftermath of 9/11. METHODS: Utility workers deployed to the WTC site were screened at their place of employment between 10 and 34 months following the WTC attacks, utilizing both structured interviews and self-report measures. PTSD symptoms were assessed by the CAPS and the PCL; co-morbid disorders were also assessed. 2,960 individuals with complete CAPS and PCL data were included in the analyses. RESULTS: Eight percent of participants had symptoms consistent with full PTSD, 9.3% with subthreshold PTSD, 6% with MDD, 3.5% with GAD, and 2.5% with panic disorder. Although risk factors included psychiatric and trauma history, 51% of individuals with probable PTSD had neither; subjective perception of threat to one's life was the best predictor of probable PTSD. Extent of exposure predicted 89% of PTSD cases in those without a psychiatric or trauma history, but only 67% of cases among those with both. CONCLUSIONS: Nonrescue workers deployed to a disaster site are at risk for PTSD and depression. Extent of exposure affected the most vulnerable workers differently than the least vulnerable ones. These results suggest that the relationship among predictors of PTSD may be different for different vulnerability groups, and underscore the importance of screening, education, and prevention programs for disaster workers.

Effectiveness of virtual reality exposure therapy for active duty soldiers in a military mental health clinic.

Exposure therapy is an evidence-based treatment for posttraumatic stress disorder (PTSD), but research evaluating its effectiveness with active duty service members is limited. This report examines the effectiveness of virtual reality exposure therapy (VRE) for active duty soldiers (N = 24) seeking treatment following a deployment to Iraq or Afghanistan. Relative to their pretreatment self-reported symptoms on the PTSD Checklist, Military Version (M = 60.92; SD = 11.03), patients reported a significant reduction at posttreatment (M = 47.08; SD = 12.70; p < .001). Sixty-two percent of patients (n = 15) reported a reliable change of 11 points or more. This study supports the effectiveness of exposure therapy for active duty soldiers and extends previous research on VRE to this population.

The longitudinal course of PTSD among disaster workers deployed to the World Trade Center following the attacks of September 11th.

This study examined the long-term mental health outcomes of 2,960 nonrescue disaster workers deployed to the World Trade Center site in New York City following the September 11, 2001 (9/11) terrorist attacks. Semistructured interviews and standardized self-report measures were used to assess the prevalence of posttraumatic stress disorder (PTSD) and other psychopathology 4 and 6 years after the attacks. Clinician-measured rates of PTSD and partial PTSD 4-years posttrauma were 8.4% and 8.9%, respectively, in a subsample of 727 individuals. Rates decreased to 5.8% and 7.7% for full and partial PTSD 6 years posttrauma. For the larger sample, self-report scores revealed probable PTSD and partial PTSD prevalence to be 4.8% and 3.6% at 4 years, and 2.4% and 1.8% at 6 years. Approximately 70% of workers never met criteria for PTSD. Although PTSD rates decreased significantly over time, many workers remained symptomatic, with others showing delayed-onset PTSD. The strongest predictors of ongoing PTSD 6 years following 9/11 were trauma history (odds ratio (OR) = 2.27, 95% confidence interval (CI) [1.06, 4.85]); the presence of major depressive disorder 1-2 years following the trauma (OR = 2.80, 95% CI [1.17, 6.71]); and extent of occupational exposure (OR = 1.31, 95% CI [1.13, 1.51]). The implications of the findings for both screening and treatment of disaster workers are discussed.

Virtual reality goes to war: a brief review of the future of military behavioral healthcare.

Numerous reports indicate that the incidence of posttraumatic stress disorder (PTSD) in returning OEF/OIF military personnel is creating a significant healthcare challenge. These findings have served to motivate research on how to better develop and disseminate evidence-based treatments for PTSD. Virtual Reality delivered exposure therapy for PTSD has been previously used with reports of positive outcomes. This article details how virtual reality applications are being designed and implemented across various points in the military deployment cycle to prevent, identify and treat combat-related PTSD in OIF/OEF Service Members and Veterans. The summarized projects in these areas have been developed at the University of Southern California Institute for Creative Technologies, a U.S. Army University Affiliated Research Center, and this paper will detail efforts to use virtual reality to deliver exposure therapy, assess PTSD and cognitive function and provide stress resilience training prior to deployment.

An intelligent virtual human system for providing healthcare information and support.

Over the last 15 years, a virtual revolution has taken place in the use of Virtual Reality simulation technology for clinical purposes. Shifts in the social and scientific landscape have now set the stage for the next major movement in Clinical Virtual Reality with the "birth" of intelligent virtual humans. Seminal research and development has appeared in the creation of highly interactive, artificially intelligent and natural language capable virtual human agents that can engage real human users in a credible fashion. No longer at the level of a prop to add context or minimal faux interaction in a virtual world, virtual humans can be designed to perceive and act in a 3D virtual world, engage in spoken dialogues with real users and can be capable of exhibiting human-like emotional reactions. This paper will present an overview of the SimCoach project that aims to develop virtual human support agents to serve as online guides for promoting access to psychological healthcare information and for assisting military personnel and family members in breaking down barriers to initiating care. The SimCoach experience is being designed to attract and engage military Service Members, Veterans and their significant others who might not otherwise seek help with a live healthcare provider. It is expected that this experience will motivate users to take the first step--to empower themselves to seek advice and information regarding their healthcare and general personal welfare and encourage them to take the next step towards seeking more formal resources if needed.
