Psychotherapy for military-related posttraumatic stress disorder: Review of the evidence

Assistance dogs help reduce mental health symptoms among Australian Defence Force veterans and emergency services personnel: A pilot study

The aim of this pilot study was to evaluate the effectiveness of two specialized Australian PTSD assistance dog programs in reducing PTSD and mental health symptoms over a one-year period. A total of 44 participants who were partnered with an assistance dog were analysed. Using an intent to treat analysis, compared to the baseline measures, all mental health outcomes exhibited statistically significant reductions in scores at the 3-month follow-up, and persisted at the 6-month, and 12-month follow-up. When comparing baseline to 3-month follow-up the effect size (Cohen's d) was strongest for stress (d = 0.993), followed by PTSD (d = 0.892), anxiety (d = 0.837). Analyses among those who also completed the waitlist-baseline assessment (n = 23) showed slight reductions in stress and depression prior to receiving their dog (whilst waiting for their dog). However, larger reductions were yielded across all mental health measures when comparing waitlist-baseline to 3-month follow-up.

The mySELF group: Recreation- and art-based group therapy as adjunct treatment for posttraumatic stress disorder

LAY SUMMARY

Military personnel and Veterans receiving psychotherapy for mental health diagnoses such as posttraumatic stress disorder (PTSD) often have only modest symptom improvement. The authors wondered whether participating in a therapeutic recreation and creative arts group along with psychotherapy would aid recovery. A 12-week program called the my Social life, Expression, Leisure and Food (mySELF) group was created that offered therapeutic recreation, art, and music therapy. A total of 36 clients, most with PTSD, who had been receiving psychotherapy for an average of three years completed the program and submitted pre- and post-group questionnaires. The authors examined leisure attitudes, quality of life, and mental health symptoms before, immediately after, and four months after the group. Results showed significant improvements in leisure attitudes, environmental quality of life and depression, anxiety, stress, and PTSD symptoms. These preliminary results suggest that therapeutic recreation, art, and music therapy are beneficial for military personnel, Veterans, and Royal Canadian Mounted Police receiving psychotherapy.

Comparing Trauma Treatment Outcomes Between Homeless and Housed Veterans in a VA PTSD Clinical Program

Homeless veterans are likely to experience Post Traumatic Stress Disorder (PTSD). Homelessness itself is traumatic, and PTSD may exacerbate homelessness risk for veterans. Often, PTSD goes untreated in this subpopulation of veterans. Our study examined trauma-focused treatment (TFT) and non-TFT initiation and completion in a sample of housed and homeless veterans being served by a PTSD clinical team in Washington, DC. Findings included a high percentage of veterans who experienced homelessness in the sample and lower treatment completion rates among homeless veterans compared to housed veterans. This difference was no longer significant when comparing only those veterans who engaged in treatment, reinforcing the critical role of treatment engagement in successful treatment completion across populations.

Psychological interventions for post-traumatic stress injuries among public safety personnel: a systematic review and meta-analysis

BACKGROUND

Public safety personnel (PSP) are exposed to potentially psychologically traumatic events (PPTE) far more often than the general public, which increases the risk for various post-traumatic stress injuries (PTSIs). While there are many evidence-based psychological interventions for PTSI, the effectiveness of each intervention for PSP remains unclear.

OBJECTIVES

The current study assessed the effectiveness and acceptability of psychological interventions for PTSI among PSPs.

METHODS

A systematic review and random-effects meta-analysis were performed on the effectiveness and acceptability of psychotherapies for PTSIs (i.e., symptoms of depression, anxiety, post-traumatic stress disorder) among PSP. The review adhered to the PRISMA reporting guidelines and used standardized mean differences (Cohen's d), rate ratios (RR), and their 95% confidence intervals (95% CI) to measure pooled effect sizes across studies; negative d values and RR values less than one indicated a reduction in symptoms compared to baseline or control groups. In addition, heterogeneity was quantified using I², and publication bias was evaluated using Egger's test.

RESULTS

The analyses included data from eight randomized controlled trials representing 402 PSP (79.4% male, 35.3 years). Psychological interventions included narrative exposure therapy (n = 1), cognitive behavioral therapy (n = 2), eclectic psychotherapy (n = 2), eye-movement desensitization and reprocessing (n = 1), supportive counseling (n = 2), and group critical incident stress debriefing (n = 1). The interventions were associated with statistically significant reductions in symptoms associated with PTSD (d = - 1.23; 95% CI - 1.81, - 0.65; 7 studies; I² = 81%), anxiety (- 0.76; 95% CI - 1.28, - 0.24; 3 studies; I² = 47%), and depression (d = - 1.10; 95% CI - 1.62, - 0.58; 5 studies; I² = 64%). There were smaller but statistically significant improvements at follow-up for symptoms of PTSD (d = - 1.29 [- 2.31, - 0.27]), anxiety (d = - 0.82 [- 1.20, - 0.44]), and depression (d = - 0.46 [- 0.77, - 0.14]). There were no statistically significant differences in dropout rates (RR = 1.00 [0.96, 1.05]), suggesting high acceptability across interventions.

CONCLUSIONS

There is preliminary evidence that psychotherapies help treat PTSIs in PSP; however, the shortage of high-quality studies on PSP indicates a need for additional research into treating PTSI among PSP.

Predictors of reintegration adjustment among female U.S. Army spouses: A preliminary exploration

LAY SUMMARY

Little is known about how military families navigate the challenges they experience during reintegration, the period after a deployment separation when a service member returns home and families must readjust to their presence. This study considers how family risk factors such as the mental health of both partners and protective factors such as social support and participation in military-sponsored training influence family adjustment during reintegration. Military spouses who reported having more social support were likely to report that their families adjusted more quickly during reintegration. However, spouses who expressed concern about a partner’s mental health were less likely to feel prepared for reintegration and, in turn, were more likely to report that their families adjusted more slowly. The results of this study suggest that supporting military spouses in feeling more prepared for reintegration may be an important means to shorten the adjustment period after a deployment.

A comparison of prolonged exposure therapy, pharmacotherapy, and their combination for PTSD: What works best and for whom; study protocol for a randomized trial

BACKGROUND

Several efficacious psychological and pharmacological treatments for posttraumatic stress disorder (PTSD) are available; however, the comparative effectiveness of these treatments represents a major gap in the literature. The proposed study will compare the effectiveness of two leading PTSD treatments - Prolonged Exposure (PE) therapy and pharmacotherapy with paroxetine or venlafaxine extended release - as well as the combination of PE and medication.

METHODS

In a randomized clinical trial, veterans with PTSD (N = 450) recruited across six Veterans Affairs Medical Centers will complete assessments at baseline, mid-treatment (Week 7), post-treatment (Week 14), and follow-up (Weeks 27 and 40). The primary outcome will be change in (both clinician-rated and self-reported) PTSD severity. Depression symptoms, quality of life, and functioning will also be measured and examined as secondary outcomes. Baseline demographic and clinical data will be used to develop "personalized advantage indices" (PAIs), with the goal of identifying who is most likely to benefit from which treatment.

CONCLUSIONS

This planned trial will yield findings to directly inform clinical practice guidelines for PTSD, by providing comparative effectiveness data to support recommendations about what can be considered the "first-line" treatment option(s) for PTSD. Further, findings from this trial have the potential to guide treatment planning for individual patients, through implementation of PAIs developed from study data, in service of "personalized medicine."

Do early responders and treatment non-responders offer guidance to make CPT group a more effective treatment?

BACKGROUND

Treatment dropout has been problematic with evidence-based treatments for posttraumatic stress disorder (PTSD), including cognitive processing therapy (CPT). This study sought to evaluate whether CPT group contributed to symptom improvement among treatment completers and non-completers.

METHODS

Sixty-one Iraq and Afghanistan combat Veterans self-selected CPT group or treatment as usual (TAU) forming a convenience sample. Defining treatment completion as attending at least nine sessions: 18 completed treatment, 20 dropped-out (DOs); 20 completed TAU, 3 lost to TAU follow-up.

RESULTS

Multiple Regression revealed significant pre-post-treatment improvement, the Clinician-Administered PTSD Scale (CAPS-IV, F(5, 40.1) = 2.53, p = 0.0436). Reviewing DOs' last available PTSD Checklist-Military Version scores before leaving treatment, six achieved clinically significant improvement of >10 points; seven a clinically reliable change of 5-10 points.

CONCLUSION

These findings highlight that CPT group may be effective at reducing trauma-related symptoms among treatment completers and dropouts and point to the utility of a clinical definition of good treatment end-state.

Associations between residual hyperarousal and insomnia symptoms in veterans following a 2-week intensive outpatient program for posttraumatic stress disorder

Many returning military service members and veterans who were deployed following the September 11, 2001, terrorist attacks (9/11) suffer from posttraumatic stress disorder (PTSD) and insomnia. Although intensive treatment programs for PTSD have shown promise in the treatment of PTSD symptoms, recent research has demonstrated that sleep disturbance shows little improvement following intensive trauma-focused treatment. The aim of the present study was to evaluate changes in self-reported insomnia symptoms among veterans and service members following participation in a 2-week intensive program for PTSD. We further aimed to investigate if residual PTSD symptoms, specifically hyperarousal, were associated with residual insomnia symptoms. Participants (N = 326) completed self-report assessments of insomnia, PTSD symptoms, and depressive symptoms at pre- and posttreatment. At pretreatment, 73.9% of participants (n = 241) met the criteria for moderate or severe insomnia, whereas at posttreatment 67.7% of participants (n = 203) met the criteria. Results of paired t tests demonstrated statistically significant differences between pre- and posttreatment Insomnia Severity Index scores; however, the effect size was small, d = 0.34. Analyses revealed that posttreatment hyperarousal symptoms were associated with posttreatment insomnia. These findings suggest that although an intensive program for service members and veterans with PTSD may significantly reduce insomnia symptoms, clinically meaningful residual insomnia symptoms remain. Further research is warranted to elucidate the association between residual hyperarousal and insomnia symptoms following intensive trauma-focused treatment.

"My heart on this bit of paper": A grounded theory of the mechanisms of change in art therapy for military veterans

BACKGROUND

A proportion of veterans experience post-traumatic stress disorder (PTSD). Research has shown reduced effectiveness of commonly offered psychotherapies in military personnel. Some research suggested the usefulness of art therapy for veterans with PTSD, but its mechanism of operation has been unclear. The current project aimed to establish participants' perceptions of any impact of group art therapy and some of the perceived mechanisms of change.

METHOD

In a grounded theory design, single semi-structured interviews were conducted with nine veterans who had received group art therapy, two art therapists, and a veteran's wife. Interviews were transcribed and analysed.

FINDINGS

Theorised categories included (a) art therapy group as "the family", (b) "the gentle conductor", (c) trust, (d) doing the work, (e) art therapy as "a communication tool", (f) "points of recognition", (g) "making things concrete", and (h) "not a cure".

LIMITATIONS

Shortcomings included a homogenous sample who all attended art therapy alongside other interventions, reliance on subjective and unmeasured symptom change, and researcher effects related to qualitative methodology.

CONCLUSION

The developed grounded theory is consistent with existing evidence and neuropsychological theory. Group art therapy may enable some veterans to prepare for verbal-only therapy, by offering a safe space in which to approach non-verbal traumatic and trauma-related contextual material in a controlled way. Artworks may provide a bridge to facilitate communication of experiences within subsequent verbal therapy and with loved-ones. It is suggested to replicate the project at different sites. Elements of the developed theory may be investigated further to establish its transferability.

Treatment With Nepicastat Decreases Contextual Traumatic Memories Persistence in Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a common anxiety mental disorder and can be manifested after exposure to a real or perceived life-threatening event. Increased noradrenaline and adrenaline in plasma and urine have been documented in PTSD. Dopamine-β-hydroxylase (DBH) catalyzes the conversion of dopamine to noradrenaline and consequently, DBH inhibition reduces catecholamines. Our aim was to evaluate if nepicastat treatment decreases PTSD signs in an animal model. Wild-type (129x1/SvJ) female mice were submitted to PTSD induction protocol. DBH-inhibitor nepicastat (30 mg/kg) or vehicle (0.2% HPMC) were administered once daily since day 0 until day 7 or 12. The percentage of freezing was calculated on days 0, 1, 2, and 7, and behavioral tests were performed. Quantification of nepicastat in plasma and DBH activity in the adrenal gland was evaluated. Catecholamines were quantified by HPLC with electrochemical detection. mRNA expression of Npas4 and Bdnf in hippocampus was evaluated by qPCR.Mice in the PTSD-group and treated with nepicastat showed a decrease in freezing, and an increase in the time spent and entries in open arms in elevated plus maze test. In mice treated with nepicastat, adrenal gland DBH activity was decreased, and catecholamines were also decreased in plasma and tissues. On day 7, in mice treated with nepicastat, there was an increase of Npas4 and Bdnf mRNA expression in the hippocampus.In conclusion, DBH inhibitor nepicastat has an effect consistent with a decrease in the persistence of traumatic memories and anxiety-like behavior in this PTSD mice model. The disruption of traumatic memories through interference with the formation, consolidation, retrieval, and/or expression processes may be important to decrease PTSD symptoms and signs. The increase in Npas4 and Bdnf mRNA expression in the hippocampus may be important to develop a weaker traumatic contextual memory after nepicastat treatment.

Enhanced Mental Health with Virtual Reality Mental Hygiene by a Veteran Suffering from PTSD

This paper describes the application and feasibility of the use of Virtual Reality Mental Hygiene (VRMH) as a mean to reduce anxiety and stress in a Danish veteran suffering from posttraumatic stress disorder (PTSD) and enduring personality change after a catastrophic experience. The results from this case study provide preliminary evidence that VRMH can be used as a mean to reduce arousal in patients with severe PTSD.

Effectiveness of a Rational Emotive Behavior Therapy (REBT)-Informed Group for Post-9/11 Veterans with Posttraumatic Stress Disorder (PTSD)

Various treatments aimed for posttraumatic stress disorder (PTSD) have been developed for veterans, but many are not formatted for use in groups, do not address common psychiatric comorbidities, and include inherent barriers (e.g., substantial time commitment). This program evaluation study aimed to examine the effectiveness of a five-session treatment, a Rational Emotive Behavior Therapy (REBT)-Informed Group focused on changing irrational beliefs to address comorbid depression and anxiety (as well as anger and guilt) among post-9/11 veterans with PTSD. Participants (n = 47) completing the REBT-Informed Group demonstrated significant reductions at posttreatment in depression and PTSD symptoms. Compared to veterans in a ten-session treatment-as-usual group (n = 47), there was no significant difference in PTSD symptom improvement despite the reduction in number of sessions. The study demonstrates that a five-week group treatment for PTSD comorbid with depression or anxiety in post-9/11 veterans - a therapy that may be uniquely suited to a military or veteran population, but potentially generalizable to civilians as well - can lead to significant reductions in depression and PTSD symptoms. Future directions include development of a manual for dissemination and replication of findings of the REBT-Informed Group to other military or Veterans Affairs medical centers.

Early discontinuation of pharmacotherapy in U.S. veterans diagnosed with PTSD and the role of psychotherapy

More than 50% of individuals who enter treatment for posttraumatic stress disorder (PTSD) are prescribed a psychotropic medication. To date, however, data are limited regarding the prevalence and determinants of discontinuation of psychotropic medication in this population. To address this gap, we analyzed data from 154,953 veterans newly diagnosed with PTSD who were seeking VA treatment and followed them for one year to identify the prevalence and determinants of medication discontinuation. A hazard analysis was conducted to identify factors associated with discontinuation of antidepressant, anxiolytic/hypnotic and antipsychotic medications. Binomial regressions examined the role of these factors in early discontinuation (within 30 days). Results revealed that 71.8% of veterans discontinued medication treatment within 180 days, and 34.6% within 30 days. The strongest risk factors associated with discontinuing medication were no engagement in adjunctive psychotherapy and prescription of a single medication. Older veterans were less likely than younger veterans to discontinue treatment. Similar risk factors were associated with medication discontinuation in the first 30 days. These results suggest that psychiatric comorbidities, age, and race are key risk factors for poor medication adherence, and underscore the importance of early intervention and patient education in promoting adherence to pharmacotherapy for PTSD.

Bayesian Time-Series Models in Single Case Experimental Designs: A Tutorial for Trauma Researchers

Single-case experimental designs (SCEDs) involve obtaining repeated measures from one or a few participants before, during, and, sometimes, after treatment implementation. Because they are cost-, time-, and resource-efficient and can provide robust causal evidence for more large-scale research, SCEDs are gaining popularity in trauma treatment research. However, sophisticated techniques to analyze SCED data remain underutilized. Herein, we discuss the utility of SCED data for trauma research, provide recommendations for addressing challenges specific to SCED approaches, and introduce a tutorial for two Bayesian models-the Bayesian interrupted time-series (BITS) model and the Bayesian unknown change-point (BUCP) model-that can be used to analyze the typically small sample, autocorrelated, SCED data. Software codes are provided for the ease of guiding readers in estimating these models. Analyses of a dataset from a published article as well as a trauma-specific simulated dataset are used to illustrate the models and demonstrate the interpretation of the results. We further discuss the implications of using such small-sample data-analytic techniques for SCEDs specific to trauma research.

Outdoor recreational activity experiences improve psychological wellbeing of military veterans with post-traumatic stress disorder: Positive findings from a pilot study and a randomised controlled trial

Exposure to the natural environment is increasingly considered to benefit psychological health. Recent reports in the literature also suggest that outdoor exposure that includes recreational pursuits such as surfing or fishing coupled with opportunities for social interaction with peers may be beneficial to Armed Forces Veterans experiencing Post-Traumatic Stress Disorder (PTSD). Two studies were conducted to evaluate this possibility. In particular, these studies aimed to test the hypothesis that a brief group outdoor activity would decrease participants’ symptoms as assessed by established measures of PTSD, depression, anxiety and perceived stress, and increase participants’ sense of general social functioning and psychological growth. Experiment one employed a repeated measures design in which UK men and women military veterans with PTSD (N = 30) participated in a group outdoor activity (angling, equine care, or archery and falconry combined). Psychological measures were taken at 2 weeks prior, 2 weeks post, and at 4 month follow up. We obtained a significant within participant main effect indicating significant reduction in PTSD symptoms. Experiment two was a waitlist controlled randomised experiment employing an angling experience (N = 18) and 2 week follow up. In experiment 2 the predicted interaction of Group (Experimental vs. Waitlist Control) X Time (2 weeks pre vs. 2 weeks post) was obtained indicating that the experience resulted in significant reduction in PTSD symptoms relative to waitlist controls. The effect size was large. Additional analyses confirmed that the observed effects might also be considered clinically significant and reliable. In sum, peer outdoor experiences are beneficial and offer potential to complement existing provision for military veterans with Post Traumatic Stress Disorder.

Manage Emotions to Reduce Aggression: A Pilot Study of a Brief Treatment to Help Veterans Reduce Impulsive Aggression

Veterans with posttraumatic stress disorder (PTSD) report more aggression than civilians with PTSD. Because emotion regulation difficulties mediated the relationship between PTSD symptoms and impulsive aggression in veterans, we developed an intervention to increase emotion regulation skills. This pilot study tested the feasibility and acceptability of a three-session treatment, Manage Emotions to Reduce Aggression (MERA), and examined its effectiveness at reducing aggression and emotion dysregulation. Male combat veterans with PTSD and impulsive aggression completed assessments before and 4 weeks after MERA. Overt Aggression Scale measured frequency of aggression; Difficulties in Emotion Regulation Scale assessed emotion dysregulation. Most veterans (95%) who completed MERA and the posttreatment assessment (n = 20) reported MERA was helpful. Veterans in the intent-to-treat sample demonstrated a significant decrease in their frequency of aggression (Cohen's d = -0.55) and emotion dysregulation (Cohen's d = -0.55). MERA may be an innovative treatment that helps veterans reduce aggression.

Psychospiritual Developmental Risk Factors for Moral Injury

There is increasing theoretical, clinical, and empirical support for the hypothesis that psychospiritual development, and more specifically, postconventional religious reasoning, may be related to moral injury. In this study, we assessed the contributions of exposure to potentially morally injurious events, posttraumatic stress symptoms, and psychospiritual development to moral injury symptoms in a sample of military veterans (N = 212). Psychospiritual development was measured as four dimensions, based on Wulff’s theory juxtaposing conventional vs. postconventional levels of religious reasoning, with decisions to be an adherent or a disaffiliate of faith. After controlling for exposure to potentially morally injurious events and severity of posttraumatic stress symptoms, veterans who were conventional disaffiliates reported higher scores on the Moral Injury Questionnaire than conventional adherents, postconventional adherents, or postconventional disaffiliates. We conclude that the role of psychospiritual development offers a theoretical approach to moral injury that invites collaboration between social scientists, philosophers, theologians, and medical professionals.

Effect of Stress on Autonomic and Cardiovascular Systems in Military Population: A Systematic Review

Stress is regulated by the autonomous nervous system, increasing the sympathetic modulation when a threat is perceived. A multifactorial response usually leads to significant behavioural modifications and alterations on homeostasis and physical and psychological status. Moreover, stress is an emotional response that can lead to psychosocial and psychophysiological adversity. Regarding military population, military operations and combat exposure are important stressors that influence acute and chronic stress response in soldiers, affecting their performance and health. A bibliographic search was carried out between April and May 2019, focusing on recent studies (2013–2019) that analysed psychophysiological response, stress, stress regulation, heart rate, heart rate variability, and posttraumatic stress disorder in military population. Autonomic and cardiovascular chronic stress seems to be modulated by experience and previous specific training of each military unit. Physical exercise, music embedded with binaural beat technology, bidirectional sensory motor rhythm training, heart rate variability biofeedback, and transcutaneous vagal nerve stimulation are the main techniques applied to balance stress and to recover body homeostasis. Since military population are usually exposed to multiple stressors, knowing previous training and experience, together with developing techniques to balance stress, is the main practical application in this field of study to balance autonomic and cardiovascular systems.

Identifying clusters of health symptoms in deployed military personnel and their relationship with probable PTSD

OBJECTIVE

Among military personnel posttraumatic stress disorder is strongly associated with non-specific health symptoms and can have poor treatment outcomes. This study aimed to use machine learning to identify and describe clusters of self-report health symptoms and examine their association with probable PTSD, other psychopathology, traumatic deployment exposures, and demographic factors.

METHOD

Data were from a large sample of military personnel who deployed to the Middle East (n = 12,566) between 2001 and 2009. Participants completed self-report measures including health symptoms and deployment trauma checklists, and several mental health symptom scales. The data driven machine learning technique of self-organised maps identified health symptom clusters and logistic regression examined their correlates.

RESULTS

Two clusters differentiated by number and severity of health symptoms were identified: a small 'high health symptom cluster' (HHSC; n = 366) and a large 'low health symptom cluster' (LHSC; n = 12,200). The HHSC had significantly higher proportions of (Gates et al., 2012 [1]) scaled scores indicative of PTSD (69% compared with 2% of LHSC members), Unwin et al. (1999a) [2] scores on other psychological scales that were indicative of psychopathology, and (Graham et al., n.d. [3]) deployment trauma. HHSC members with probable PTSD had a stronger relationship with subjective (OR 1.25; 95% CI 1.12, 1.40) and environmental (OR 1.08; 95% CI 1.03, 1.13) traumatic deployment exposures than LHSC members with probable PTSD.

CONCLUSION

These findings highlights that health symptoms are not rare in military veterans, and that PTSD is strongly associated with health symptoms. Results suggest that there may be subtypes of PTSD, differentiated by health symptoms.

Factors Associated With Receipt of Cognitive-Behavioral Therapy or Prolonged Exposure Therapy Among Individuals With PTSD

OBJECTIVE

The aim of this study was to systematically review variables associated with initiation of trauma-centered cognitive-behavioral therapy (TC-CBT) among individuals with posttraumatic stress disorder (PTSD).

METHODS

PubMed, PsycINFO, Web of Science, Published International Literature on Traumatic Stress (PILOTS), and Scopus were searched in a systematic manner up to 2018, and 26 relevant studies were recovered and analyzed.

RESULTS

The average weighted initiation rate was 6% in larger hospital systems with a high rate of trauma and 28% in outpatient mental health settings (range 4%-83%). Older age (odds ratio [OR]=1.56, 95% confidence interval [CI]=0.51-1.61), female gender (OR=1.18, 95% CI=1.08-1.27), black or other racial-ethnic minority group (OR=1.16, 95% CI=1.03-1.28), Veterans Affairs PTSD service connection status (OR=2.30, 95% CI=2.18-2.42), mental health referral (OR=2.28, 95% CI=1.05-3.50), greater staff exposure to TC-CBT (OR=2.30, 95% CI=2.09-2.52), adaptability of TC-CBT to staff workflow (OR=4.66, 95% CI=1.60-7.72), greater PTSD severity (OR=1.46, 95% CI=1.13-1.78), and comorbid depression (OR=1.21, 95% CI=1.14-1.29) increased the likelihood of TC-CBT initiation, whereas delayed treatment reduced the likelihood of TC-CBT initiation (OR=0.93, 95% CI=0.92-0.95). Qualitative studies showed that mental health beliefs (stigma and lack of readiness), provider organizational factors (low availability, privacy issues), and patient lack of time (logistics) were perceived as barriers to initiation by patients and providers.

CONCLUSIONS

TC-CBT initiation increased among patients who were older and female. Initiation was also higher among providers who had more exposure to TC-CBT in their work environment and when TC-CBT fit into their existing workflow.

Predictors of Treatment Adequacy During Evidence-Based Psychotherapy for PTSD

OBJECTIVE

The U.S. Department of Veterans Affairs (VA) has placed increased emphasis on the availability and use of evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD). However, many individuals do not complete a full course of EBP. The current study aimed to quantify the percentage of veterans receiving adequate EBP in VA hospitals and identify factors related to treatment completion.

METHODS

A national sample of 16,559 VA patients who began cognitive processing therapy (CPT) or prolonged exposure (PE) during fiscal year 2015 was obtained via administrative data. Generalized estimating equations were used to evaluate individual-level predictors of treatment adequacy, defined as eight sessions within 14 weeks. Generalized linear models were used to examine facility-level factors.

RESULTS

A total of 5,142 (31.1%) veterans completed eight or more sessions of psychotherapy. Older age was associated with greater odds of completing eight or more sessions (odds ratio OR=1.02, 95% confidence interval [CI]=1.01, 1.02, p<0.001), and comorbid bipolar or psychotic disorders were associated with reduced odds of completion (OR=0.89, 95% CI=0.80, 0.99, p=0.03). The percentage of patients who completed eight or more sessions was higher at facilities with higher percentages of EBP use among all patients with PTSD (β=6.55, SE=1.97, p=0.001) and greater numbers of EBP-certified providers (β=0.004, SE=0.002, p=0.038) and lower at facilities with a higher percentage of patients receiving a PTSD Checklist (β=-1.16, SE=0.46, p=0.011).

CONCLUSIONS

A minority of VA patients with PTSD complete an adequate dose of EBPs for PTSD. Individual and facility-level factors related to treatment adequacy may point to opportunities for intervention.

Conceptualization, Assessment, and Treatment of Traumatic Stress in First Responders: A Review of Critical Issues

First responders are regularly confronted with exposure to traumatic events, including potentially life-threatening situations as well as the grave injuries and deaths of colleagues and civilians. Evidence indicates that the prevalence of posttraumatic stress disorder (PTSD) is substantially higher among first responders than the general population. This article provides information about the outpatient trauma services at McLean Hospital's LEADER (Law Enforcement, Active Duty, Emergency Responder) program to assist clinicians who encounter these first responders in their practices or who are specifically interested in working with this patient population. We begin by synthesizing the literature on the prevalence of PTSD in first responders following work-related exposure to traumatic stress, and by addressing the occupation-specific risk factors and the third-variable risk factors that may contribute to potentiated risk. We then discuss assessment strategies and treatment options used in our program, which is tailored for individuals who are dealing with mental health issues stemming from occupation-specific traumatic-stress exposure. We also address the unique challenges of treating traumatized first responders with more complex issues such as traumatic stress exposure across the lifespan and safety issues, including acute suicidality. We conclude by discussing notable gaps in the literature, including the need to investigate why and how women present with different PTSD symptoms than men and how these differences need to be taken into account in determining appropriate treatment for women.

"It didn't fit for me:" A qualitative examination of dropout from prolonged exposure and cognitive processing therapy in veterans

Trauma-focused psychotherapies, such as prolonged exposure and cognitive processing therapy, are the most effective forms of treatment for posttraumatic stress disorder. These treatments are commonly delivered in the Veterans Health Administration; however, dropout means that some veterans fail to benefit. Ending treatment prematurely is a common problem across psychotherapies, with on average, 20% to 25% of patients dropping out. The purpose of this study was to examine veterans' self-reported reasons for dropping out of prolonged exposure or cognitive processing therapy. Veterans who dropped out from prolonged exposure or cognitive processing therapy (N = 28) completed qualitative interviews about their experiences. Interviews were coded by 2 coders using grounded theory. Therapy-related barriers were the largest category reported, and included lack of buy-in to the rationale or specific therapy tasks, believing that treatment was not working, alliance issues, or switching to a different treatment. Practical barriers and finding treatment "too stressful" were also common reasons for dropout. This research provides information that can shape how PTSD treatments are delivered in health care settings. Therapy-related barriers were the largest group, suggesting that providers may need to find more effective ways to communicate the rationale for these therapies or to tailor them to individual patients' needs.

Use of Reflective Journaling to Understand Decision Making Regarding Two Evidence-Based Psychotherapies for PTSD: Practice Implications

As part of a longitudinal investigation on implementation of 2 evidence-based psychotherapies (EBPs) for posttraumatic stress disorder, psychotherapists from 38 Department of Veterans Affairs residential treatment programs across the United States were asked to complete reflective journals every 4 months for a 1-year time period in regard to their successes and challenges in using prolonged exposure and cognitive processing therapy. This paper provides content analysis on the reflective journals of 24 of these providers. Five main themes were identified: EBPs are great but not sufficient for patients in residential treatment with chronic posttraumatic stress disorder and complicated life circumstances, and thus, more treatment is necessary after discharge. Modifications were made or thought needed for optimal outcome and successful delivery of these 2 EBPs; some providers blended aspects of prolonged exposure and cognitive processing therapy; what happens when providers and patients do not agree on choice of which EBP to first implement; and provider concerns on when to discontinue an EBP. Reflective journaling appears to be a promising way for trainers and treatment developers to gather important information about the clinical application and decision-making process for front-line providers, which may offer insight into how to improve EBP implementation and sustainability. Incorporating reflective journaling and strategies for accomplishing this into training, supervision, and consultation may also be 1 strategy for increasing feedback, expanding implementation, and informing ways to increase sustainability of EBPs in populations with multiple clinical and psychosocial needs.

Reconsolidation of Traumatic Memories for PTSD: A randomized controlled trial of 74 male veterans

Design: A randomized waitlist-controlled design (n = 74) examined the efficacy of Reconsolidation of Traumatic Memories (RTM) among male veterans with current-month flashbacks and nightmares. Volunteers were randomly assigned to immediate treatment (three 120-minute sessions of RTM), or to a 3-week waiting condition before receiving the RTM treatment. Blinded psychometricians evaluated the symptoms at intake, 2 weeks, and 6 weeks post. Wait-listed participants were re-evaluated and then treated. Sixty-five volunteers completed the treatment. Results: Of those treated, 46 (71%) lost DSM diagnosis for post-traumatic stress disorder (PTSD) by one of the following definitions: 42 persons (65%) were in complete remission (PTSD Symptom Scale Interview (PSS-I) ≤ 20 and DSM criteria not met). Four others (6%) lost the DSM diagnosis or were otherwise sub-clinical by dichotomous criteria (PSS-I < 20 and absence of flashbacks and nightmares) but non-ambiguous on the PTSD Checklist Military Version measures. Within-group RTM effect sizes (Hedges' g) for PSS-I score changes ranged from 1.45 to 2.3. The between-group comparison between the treatment group and the untreated controls was significant (p < .001) with an effect size equivalent to two standard deviations (g = 2.13; 95% CI [1.56, 2.70]). Patient satisfaction with the intervention was high. Conclusions: RTM shows promise as a brief, cost-effective intervention for PTSD characterized primarily by intrusive symptoms. Clinical or methodological significance of this article: The article provides evidence to support a fast (5 hours or fewer) robust intervention for PTSD characterized by intrusive symptoms including current-month flashbacks, nightmares, and accompanied by sympathetic arousal in response to trauma narratives. The intervention is well tolerated and has demonstrated efficacy up to one year.

Psychotherapeutic Intervention in the Demobilization Process: Addressing Combat-related Mental Injuries with Narrative Exposure in a First and Second Dissemination Stage

BACKGROUND

Depending on the exposure to traumatic stressors and combat, 20% to 50% of ex-combatants present with trauma-related disorders, and more than half of the members of armed groups have a proclivity to violence. Therefore, psychotherapeutic assistance should address both, trauma-related suffering and the lowered threshold for aggressive behaviour.

OBJECTIVE

Supporting the demobilization process of ex-combatants in the eastern DR-Congo, we implemented a version of Narrative Exposure Therapy adapted for Forensic Offender Rehabilitation (FORNET).

METHOD

In two successive dissemination stages (DS), local counsellors conducted FORNET. In DS1, they were trained by clinical experts, and in DS2, the by then experienced counsellors trained and supervised a second group of local counsellors (DS2). The training consisted of a 3-week workshop covering theoretical concepts and practical therapeutic skills. In DS1 and DS2, a total of 98 demobilizing combatants received an intervention; treatment-as-usual served as the control condition. Posttraumatic stress disorder, appetitive aggression, depression severity and drug dependence were assessed prior to the intervention and 6 and 12 months later; additionally, we assessed reintegration success.

RESULTS

Six months post-intervention, FORNET significantly reduced Posttraumatic stress disorder symptoms but had less effect on the trait of appetitive aggression; moreover, beneficial effects were found for depression severity and drug dependence as well as for reintegration indices. Treatment gains were retained at 12 months.

CONCLUSIONS

Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET and support the demobilization process in ongoing conflicts. The study suggests that it is possible to pass down psychotherapeutic techniques over generations of counsellors. © 2015 The Authors.

KEY PRACTITIONER MESSAGE

Posttraumatic stress symptoms, depression and clinically relevant levels of drug dependence can effectively be reduced with a version of Narrative Exposure Therapy (NET) adapted for Forensic Offender Rehabilitation (FORNET). The intervention is effective in the context of ongoing conflict. Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET. It is possible to pass down psychotherapeutic techniques like FORNET over generations of counsellors. Psychotherapeutic interventions like FORNET may facilitate the transition to peace in war-torn regions.

Effect and safety of sertraline for treat posttraumatic stress disorder: a multicenter randomised controlled study

OBJECTIVE

Although several previous studies have examined the efficacy of sertraline in the treatment of posttraumatic stress disorder (PTSD), none involved Chinese PTSD patients. This study aimed to evaluate sertraline efficacy and adverse events in Chinese patients with PTSD over 12 weeks.

METHODS

In total, 72 PTSD patients were randomly assigned to receive sertraline (135 mg daily) or a placebo for 12 weeks. Impact of Event Scale-Revised subscores constituted the primary outcome, with Clinical Global Impression Scale-Severity scores and adverse events as secondary outcomes.

RESULTS

Sixty-five subjects completed the study, and their data were included in the final analysis. Sertraline showed greater efficacy in enhancing Impact of Event Scale-Revised and Clinical Global Impression Scale-Severity scores at 6 and 12 weeks relative to that of the placebo. The most common adverse event was nausea, which occurred in 12 (33.3%) and 8 (22.2%) patients in the sertraline and placebo groups, respectively. No sertraline-related deaths were recorded.

CONCLUSIONS

In summary, we demonstrated that 12 weeks of sertraline was efficacious and well-tolerated in Chinese patients with PTSD.

The impact of changes in distress tolerance on PTSD symptom severity post-treatment among veterans in residential trauma treatment

Given that rates of PTSD, particularly among military populations, are increasing, it is critical to gain a better understanding of factors associated with treatment response. Low distress tolerance (DT), conceptualized as the perceived or actual inability to tolerate negative emotional states, may impacts veterans' responses to PTSD treatment. Low DT has been associated with more severe PTSD symptoms in clinical and non-clinical samples; however, its impact on PTSD symptomatology across treatment has yet to be assessed. We examined the impact of changes in DT, from intake to discharge, on post-treatment PTSD symptom severity within two samples of veterans recruited from Veterans Affairs residential PTSD treatment facilities in the northwestern and southern United States (Total N=86; 87% male; 46% White, 39% Black, 9% Latino, 6% Other). Veterans completed the Distress Tolerance Scale and PTSD Checklist (PCL) at intake and discharge from residential PTSD treatment. Regression analyses revealed that, within each veteran sample, those with the greatest improvements in DT had the lowest PCL total and subscale scores at discharge after controlling for respective intake PCL scores. This suggests increases in DT across treatment help explain the degree of benefits experienced by veterans following PTSD treatment.

Combat-Related Multifaceted Trauma-Focused Group Therapy: A Pilot Study

The efficacy of combat-related trauma-focused group therapy (TFGT) was tested using a unique technique that combines principles from prolonged exposure, cognitive processing therapy, and art therapy. Eighty Israeli male veterans exposed to traumatic events participated in the study. They were divided into eight therapeutic groups led by four pairs of trained therapists. Posttraumatic stress disorder and depression symptoms and levels of functioning were taken at pretherapy, end of therapy, and 6 months posttherapy. Analyses found that therapy helped in reducing posttraumatic and depressive symptoms at the end of therapy and at 6 months follow-up. It also showed that patients' functioning had significantly improved by the end of therapy and at 6 months follow-up. A significant clinical change in each parameter over time was also observed. In conclusion, the study provides preliminary evidence that combat-related TFGT may be efficacious in reducing psychological suffering and enhancing actual functioning. Follow-up randomized controlled trials to determine treatment efficacy are needed.

Feasibility, qualitative findings and satisfaction of a brief Tai Chi mind-body programme for veterans with post-traumatic stress symptoms

OBJECTIVE

To examine feasibility, qualitative feedback and satisfaction associated with a 4-session introduction to Tai Chi for veterans with post-traumatic stress symptoms.

DESIGN

We observed and reported recruitment and retention rates, participant characteristics, adherence, and satisfaction across 2 cohorts. We also examined qualitative feedback provided by questionnaires, focus groups and individual interviews.

MAIN OUTCOME MEASURES

Rates of recruitment and retention, focus group and individual feedback interviews, self-reported satisfaction.

PARTICIPANTS

17 veterans with post-traumatic stress symptoms.

RESULTS

Almost 90% (17/19) of those eligible following the telephone screen enrolled in the programme. Three-quarters (76.4%) of the participants attended at least 3 of the 4 Tai Chi sessions. Qualitative data analysis revealed themes indicating favourable impressions of the Tai Chi sessions. In addition, participants reported feeling very engaged during the sessions, and found Tai Chi to be helpful for managing distressing symptoms (ie, intrusive thoughts, concentration difficulties, physiological arousal). Participants also reported high satisfaction: 93.8% endorsed being very or mostly satisfied with the programme. All participants (100%) indicated that they would like to participate in future Tai Chi programmes and would recommend it to a friend.

CONCLUSIONS

Tai Chi appears to be feasible and safe for veterans with symptoms of post-traumatic stress disorder (PTSD), is perceived to be beneficial and is associated with high rates of satisfaction. This study highlights the need for future investigation of Tai Chi as a novel intervention to address symptoms of PTSD.

A Dynamic Model of Post-Traumatic Stress Disorder for Military Personnel and Veterans

Post-traumatic stress disorder (PTSD) stands out as a major mental illness; however, little is known about effective policies for mitigating the problem. The importance and complexity of PTSD raise critical questions: What are the trends in the population of PTSD patients among military personnel and veterans in the postwar era? What policies can help mitigate PTSD? To address these questions, we developed a system dynamics simulation model of the population of military personnel and veterans affected by PTSD. The model includes both military personnel and veterans in a “system of systems.” This is a novel aspect of our model, since many policies implemented at the military level will potentially influence (and may have side effects on) veterans and the Department of Veterans Affairs. The model is first validated by replicating the historical data on PTSD prevalence among military personnel and veterans from 2000 to 2014 (datasets from the Department of Defense, the Institute of Medicine, the Department of Veterans Affairs, and other sources). The model is then used for health policy analysis. Our results show that, in an optimistic scenario based on the status quo of deployment to intense/combat zones, estimated PTSD prevalence among veterans will be at least 10% during the next decade. The model postulates that during wars, resiliency-related policies are the most effective for decreasing PTSD. In a postwar period, current health policy interventions (e.g., screening and treatment) have marginal effects on mitigating the problem of PTSD, that is, the current screening and treatment policies must be revolutionized to have any noticeable effect. Furthermore, the simulation results show that it takes a long time, on the order of 40 years, to mitigate the psychiatric consequences of a war. Policy and financial implications of the findings are discussed.

Selective prevention of combat-related post-traumatic stress disorder using attention bias modification training: a randomized controlled trial

BACKGROUND

Efficacy of pre-trauma prevention for post-traumatic stress disorder (PTSD) has not yet been established in a randomized controlled trial. Attention bias modification training (ABMT), a computerized intervention, is thought to mitigate stress-related symptoms by targeting disruptions in threat monitoring. We examined the efficacy of ABMT delivered before combat in mitigating risk for PTSD following combat.

METHOD

We conducted a double-blind, four-arm randomized controlled trial of 719 infantry soldiers to compare the efficacy of eight sessions of ABMT (n = 179), four sessions of ABMT (n = 184), four sessions of attention control training (ACT; n = 180), or no-training control (n = 176). Outcome symptoms were measured at baseline, 6-month follow-up, 10 days following combat exposure, and 4 months following combat. Primary outcome was PTSD prevalence 4 months post-combat determined in a clinical interview using the Clinician-Administered PTSD Scale. Secondary outcomes were self-reported PTSD and depression symptoms, collected at all four assessments.

RESULTS

PTSD prevalence 4 months post-combat was 7.8% in the no-training control group, 6.7% with eight-session ABMT, 2.6% with four-session ABMT, and 5% with ACT. Four sessions of ABMT reduced risk for PTSD relative to the no-training condition (odds ratio 3.13, 95% confidence interval 1.01-9.22, p < 0.05, number needed to treat = 19.2). No other between-group differences were found. The results were consistent across a variety of analytic techniques and data imputation approaches.

CONCLUSIONS

Four sessions of ABMT, delivered prior to combat deployment, mitigated PTSD risk following combat exposure. Given its low cost and high scalability potential, and observed number needed to treat, research into larger-scale applications is warranted. The ClinicalTrials.gov identifier is NCT01723215.

Baseline psychophysiological and cortisol reactivity as a predictor of PTSD treatment outcome in virtual reality exposure therapy

Baseline cue-dependent physiological reactivity may serve as an objective measure of posttraumatic stress disorder (PTSD) symptoms. Additionally, prior animal model and psychological studies would suggest that subjects with greatest symptoms at baseline may have the greatest violation of expectancy to danger when undergoing exposure based psychotherapy; thus treatment approaches which enhanced the learning under these conditions would be optimal for those with maximal baseline cue-dependent reactivity. However methods to study this hypothesis objectively are lacking. Virtual reality (VR) methodologies have been successfully employed as an enhanced form of imaginal prolonged exposure therapy for the treatment of PTSD. Our goal was to examine the predictive nature of initial psychophysiological (e.g., startle, skin conductance, heart rate) and stress hormone responses (e.g., cortisol) during presentation of VR-based combat-related stimuli on PTSD treatment outcome. Combat veterans with PTSD underwent 6 weeks of VR exposure therapy combined with either d-cycloserine (DCS), alprazolam (ALP), or placebo (PBO). In the DCS group, startle response to VR scenes prior to initiation of treatment accounted for 76% of the variance in CAPS change scores, p < 0.001, in that higher responses predicted greater changes in symptom severity over time. Additionally, baseline cortisol reactivity was inversely associated with treatment response in the ALP group, p = 0.04. We propose that baseline cue-activated physiological measures will be sensitive to predicting patients' level of response to exposure therapy, in particular in the presence of enhancement (e.g., DCS).

The Use of Both Prolonged Exposure and Cognitive Processing Therapy in the Treatment of a Person With PTSD, Multiple Traumas, Depression, and Suicidality

Despite a high prevalence of comorbid disorders such as major depressive disorder (MDD), the empirical guidelines for how to manage co-occurring conditions in the treatment of posttraumatic stress disorder (PTSD) are lacking. In the context of a complicated presentation of PTSD, this case illustration demonstrates the application of an integrated treatment approach with “Amanda,” a 28-year-old female with a history of multiple traumas, undiagnosed PTSD for 10 years, and comorbid MDD. In addition, Amanda began having suicidal thoughts mid-treatment. This case study demonstrates how the integration of coping skills training and cognitive processing therapy, in conjunction with prolonged exposure, helped Amanda successfully complete treatment and be able to discuss her traumatic events with minimal distress. At discharge, Amanda no longer met criteria for PTSD, had experienced significant improvements in depression and anxiety symptoms, and was no longer experiencing suicidal thoughts. These improvements were maintained at both 3 and 6 months post treatment.
