Deep brain stimulation of the amygdala for treatment-resistant combat post-traumatic stress disorder: Long-term results.

Deep brain stimulation (DBS) holds promise for neuropsychiatric conditions where imbalance in network activity contributes to symptoms. Treatment-resistant Combat post-traumatic stress disorder (TR-PTSD) is a highly morbid condition and 50% of PTSD sufferers fail to recover despite psychotherapy or pharmacotherapy. Reminder-triggered symptoms may arise from inadequate top-down ventromedial prefrontal cortex (vmPFC) control of amygdala reactivity. Here, we report long-term data on two TR-PTSD participants from an investigation utilizing high-frequency amygdala DBS. The two combat veterans were implanted bilaterally with quadripolar electrodes targeting the basolateral amygdala. Following a randomized staggered onset, patients received stimulation with adjustments based on PTSD symptom severity for four years while psychiatric and neuropsychiatric symptoms, neuropsychological performance, and electroencephalography were systematically monitored. Evaluation of vmPFC-Amygdala network engagement was assessed with 18FDG positron emission tomography (PET). CAPS-IV scores varied over time, but improved 55% from 119 at baseline to 53 at 4-year study endpoint in participant 1; and 44%, from 68 to 38 in participant 2. Thereafter, during 5 and 1.5 years of subsequent clinical care respectively, long-term bilateral amygdala DBS was associated with additional, clinically significant symptomatic and functional improvement. There were no serious stimulation-related adverse psychiatric, neuropsychiatric, neuropsychological, neurological, or neurosurgical effects. In one subject, symptomatic improvement was associated with an intensity-dependent reduction in amygdala theta frequency power. In our two participants, FDG-PET findings were inconclusive regarding the hypothesized mechanism of suppression of amygdala hyperactivity. Our findings encourage further research to confirm and extend our preliminary observations.

Acupuncture for Combat-Related Posttraumatic Stress Disorder: A Randomized Clinical Trial.

Importance: Current interventions for posttraumatic stress disorder (PTSD) are efficacious, yet effectiveness may be limited by adverse effects and high withdrawal rates. Acupuncture is an emerging intervention with positive preliminary data for PTSD. Objective: To compare verum acupuncture with sham acupuncture (minimal needling) on clinical and physiological outcomes. Design, Setting, and Participants: This was a 2-arm, parallel-group, prospective blinded randomized clinical trial hypothesizing superiority of verum to sham acupuncture. The study was conducted at a single outpatient-based site, the Tibor Rubin VA Medical Center in Long Beach, California, with recruitment from April 2018 to May 2022, followed by a 15-week treatment period. Following exclusion for characteristics that are known PTSD treatment confounds, might affect biological assessment, indicate past nonadherence or treatment resistance, or indicate risk of harm, 93 treatment-seeking combat veterans with PTSD aged 18 to 55 years were allocated to group by adaptive randomization and 71 participants completed the intervention protocols. Interventions: Verum and sham were provided as 1-hour sessions, twice weekly, and participants were given 15 weeks to complete up to 24 sessions. Main Outcomes and Measures: The primary outcome was pretreatment to posttreatment change in PTSD symptom severity on the Clinician-Administered PTSD Scale-5 (CAPS-5). The secondary outcome was pretreatment to posttreatment change in fear-conditioned extinction, assessed by fear-potentiated startle response. Outcomes were assessed at pretreatment, midtreatment, and posttreatment. General linear models comparing within- and between-group were analyzed in both intention-to-treat (ITT) and treatment-completed models. Results: A total of 85 male and 8 female veterans (mean [SD] age, 39.2 [8.5] years) were randomized. There was a large treatment effect of verum (Cohen d, 1.17), a moderate effect of sham (d, 0.67), and a moderate between-group effect favoring verum (mean [SD] Δ, 7.1 [11.8]; t90 = 2.87, d, 0.63; P = .005) in the intention-to-treat analysis. The effect pattern was similar in the treatment-completed analysis: verum d, 1.53; sham d, 0.86; between-group mean (SD) Δ, 7.4 (11.7); t69 = 2.64; d, 0.63; P = .01). There was a significant pretreatment to posttreatment reduction of fear-potentiated startle during extinction (ie, better fear extinction) in the verum but not the sham group and a significant correlation (r = 0.31) between symptom reduction and fear extinction. Withdrawal rates were low. Conclusions and Relevance: The acupuncture intervention used in this study was clinically efficacious and favorably affected the psychobiology of PTSD in combat veterans. These data build on extant literature and suggest that clinical implementation of acupuncture for PTSD, along with further research about comparative efficacy, durability, and mechanisms of effects, is warranted.

Outcome metrics utilized in evaluations of programs and interventions for combat and operational stress: A review of psychometric properties.

The Department of Defense has mandated combat and operational stress control (COSC) efforts for the Services since 1999. Although several COSC-related programs have been implemented, few have undergone evaluation, and no standardized metrics have been established to assess their effectiveness and utility. The purpose of this review was to characterize the content and psychometrics of measures that have been utilized as outcome metrics in evaluations of COSC-related programs and interventions. Systematic literature searches were conducted for publications that: a) evaluated at least one measure from U.S. service members who participated in a program or intervention to prevent or reduce the adverse effects of combat and operational stress; and b) reported U.S. data on the internal consistency, test-retest reliability, convergent validity, and sensitivity/specificity of the identified measures. This process identified 15 measures for which psychometric properties were reviewed for acceptability based on recommended criteria. Identified measures varied from well-validated measures to newer instruments for which more data is needed on one or more of the target psychometric properties. Aside from internal consistency, psychometric data from U.S. military samples were sparse. Results further suggested that some measures might have reduced sensitivity in service members under certain conditions, such as large-scale screening. Additional studies are needed to validate COSC-relevant measures in service members. Future evaluations of programs and interventions for combat and operational stress should select measures that will increase the consistency of the literature, allow comparisons across studies, and ensure alignment with the objectives of identified programs.

Massed cognitive processing therapy for combat-related posttraumatic stress disorder: Study design and methodology of a non-inferiority randomized controlled trial.

BACKGROUND: Posttraumatic stress disorder (PTSD) is prevalent among military personnel. Cognitive processing therapy (CPT) is identified as one of the most effective treatments for PTSD, although smaller effects have been found in military populations. High rates of dropout from treatment may contribute to reduced efficacy, and military personnel may face unique barriers to treatment completion. One method of improving efficacy may be to reduce dropout by decreasing the time required to receive a full dose of treatment. This paper describes the design and methodology of the first randomized clinical trial testing whether CPT delivered in an intensive format is non-inferior to standard delivery of CPT. METHOD: Participants are 140 active duty service members randomized to receive CPT in a 5-day combined group and individual intensive outpatient format (MCPT) or standard CPT (delivered individually twice weekly over 6 weeks). Participants are assessed at baseline, and 1 month, 4 months, and 1 year following the conclusion of the therapy. Reduction in PTSD symptomatology is the primary outcome of interest. Secondary outcomes include comorbid psychological symptoms, health, and functioning. A secondary objective is to examine predictors of treatment outcome to determine which service members benefit most from which treatment modality. CONCLUSION: If determined to be non-inferior, MCPT would provide an efficient and accessible modality of evidence-based PTSD treatment. This therapy format would improve access to care by reducing the amount of time required for treatment and improving symptoms and functioning more rapidly, thereby minimizing interference with work-related activities and disruption to the mission.

Delayed-onset posttraumatic stress disorder with response to methylphenidate / Trastorno por estrés postraumático de expresión retardada con respuesta a metilfenidato

Introduction: Posttraumatic stress disorder (PTSD) is extremely frequent in war veterans and has been widely studied. However, the efficacy of currently available pharmacological and psychotherapeutic treatments of war PTSD and other causes of PTSD is very limited. Method We present a case of war PTSD with delayed expression, with a good response to complementation with methylphenidate after a failed treatment with venlafaxine and risperidone. Results We review the role of dopamine in the pathophysiology of PTSD and the scarce studies in the treatment of PTSD with dopaminergic drugs that show an improvement in re-experimentation and in affective symptoms, especially anhedonia and cognitive impairment. Conclusions We conclude that the use of methylphenidate and other dopaminergic drugs can be a promising treatment for PTSD, a high prevalent disease with a high resistance to treatment, for which we encourage the use of large sample studies.

Introducción: El trastorno por estrés postraumático (TEPT) es extremadamente prevalente en veteranos de guerra y ha sido ampliamente estudiado. Sin embargo, la eficacia de los tratamientos farmacológicos y psicoterapéuticos disponibles es aún muy limitada, tanto en el TEPT de guerra como en el TEPT por otras causas. Método Presentamos un caso de TEPT de guerra con expresión retardada, con una buena respuesta al metilfenidato a su tratamiento con venlafaxina y risperidona, que había resultado ineficaz. Resultados Revisamos el rol de la dopamina en la psicopatología del TEPT y los pocos estudios del tratamiento del TEPT con fármacos dopaminérgicos, en los que se muestra una mejoría en los síntomas de reexperimentación y los síntomas afectivos, especialmente la anhedonia y los déficits cognitivos secundarios. Conclusiones Consideramos que el uso del metilfenidato y de otros fármacos dopaminérgicos podrían ser prometedores el tratamiento del TEPT, un trastorno altamente prevalente y con alta resistencia al tratamiento habitual. Por esto, animamos a realizar estudios con muestras amplias. (AU)

Quantitative changes in mental health measures with 3MDR treatment for Canadian military members and veterans.

OBJECTIVE: Military members and veterans are at elevated risk of treatment-resistant posttraumatic stress disorder (TR-PTSD) due to higher rates of exposure to potentially traumatic events during the course of duty. Knowledge of TR-PTSD is limited, and specific protocols or evidence-based TR-PTSD therapies are lacking. Multimodal motion-assisted memory desensitization and reconsolidation (3MDR) therapy is an emerging intervention for combat-related TR-PTSD. The purpose of this study was to preliminarily assess the effectiveness of 3MDR in addressing TR-PTSD in Canadian military members and veterans. METHODS: This study is a longitudinal mixed-methods clinical trial. English-speaking military members and veterans aged 18-60 with TR-PTSD were recruited to participate. The intervention consisted of six sessions of 3MDR therapy. Quantitative data were collected pretreatment, posttreatment, and longitudinally at 1, 3, and 6 months after completion of 3MDR. RESULTS: Results from the first 11 participants to complete the 3MDR protocol exhibited statistically significant improvement (surviving multiple comparison correction) in clinically administered and self-reported scores for PTSD (CAPS-5 and PCL-5), moral injury (MISS-M-SF), depression (PHQ-9), anxiety (GAD-7), emotional regulation (DERS-18), and resilience (CD-RS-25). CONCLUSION: The preliminary and exploratory results from this clinical trial support the growing body of literature illustrating 3MDR as an effective treatment for military-related TR-PTSD. These results are notable given participants' previous lack of success with frontline psychotherapeutic and pharmacological interventions. Given that there are currently very limited treatment options for TR-PTSD, 3MDR could prove to be a valuable treatment option for military members and veterans with TR-PTSD.

Elton Mayo and Thomas Henry Reeve Mathewson: the forgotten Australian pioneers of the treatment of patients with shell shock, neurasthenia and nervous breakdown.

The contributions of Australians on shell shock are absent from the literature. However, two Australians were pioneers in the treatment of shell shock: George Elton Mayo (1880-1949) and Dr Thomas Henry Reeve Mathewson (1881-1975). They used psychoanalytic approaches to treat psychiatric patients and introduced the psychoanalytic treatment of people who suffered from shell shock. Their 'talking cure' was highly successful and challenged the view that shell shock only occurred in men who were malingering and/or lacking in fortitude. Their work demonstrated that people experiencing mental illness could be treated in the community at a time when they were routinely treated as inpatients. It also exemplified the substantial benefits of combining science with clinical knowledge and skill in psychology and psychiatry.

Functional neurology after the Second World War: The beginnings of neurology on screen (III).

Treatment of functional symptoms has a long history, and interventions were often used in soldiers returning from battle. On the 75th anniversary of the end of the Second World War, I review the portrayal of neurology in documentary film. Two documentaries were released in 1946 and 1948 (Let There Be Light and Shades of Gray, respectively), which showed a number of soldiers with functional neurology including paralysis, stuttering, muteness, and amnesia. The films showed successful treatments with hypnosis and sodium amytal by psychoanalytic psychiatrists. These documentaries link neurology with psychiatry and are remarkable examples of functional neurology and its treatment on screen.

Trauma, treatment and Tetris: video gaming increases hippocampal volume in male patients with combat-related posttraumatic stress disorder.

Background: Tetris has been proposed as a preventative intervention to reduce intrusive memories of a traumatic event. However, no neuroimaging study has assessed Tetris in patients with existing posttraumatic stress disorder (PTSD) or explored how playing Tetris may affect brain structure. Methods: We recruited patients with combat-related PTSD before psychotherapy and randomly assigned them to an experimental Tetris and therapy group (n = 20) or to a therapy-only control group (n = 20). In the control group, participants completed therapy as usual: eye movement desensitization and reprocessing (EMDR) psychotherapy. In the Tetris group, in addition to EMDR, participants also played 60 minutes of Tetris every day from onset to completion of therapy, approximately 6 weeks later. Participants completed structural MRI and psychological questionnaires before and after therapy, and we collected psychological questionnaire data at follow-up, approximately 6 months later. We hypothesized that the Tetris group would show increases in hippocampal volume and reductions in symptoms, both directly after completion of therapy and at follow-up. Results: Following therapy, hippocampal volume increased in the Tetris group, but not the control group. As well, hippocampal increases were correlated with reductions in symptoms of PTSD, depression and anxiety between completion of therapy and follow-up in the Tetris group, but not the control group. Limitations: Playing Tetris may act as a cognitive interference task and as a brain-training intervention, but it was not possible to distinguish between these 2 potential mechanisms. Conclusion: Tetris may be useful as an adjunct therapeutic intervention for PTSD. Tetris-related increases in hippocampal volume may ensure that therapeutic gains are maintained after completion of therapy.

Changes in physiological reactivity in response to the trauma memory during prolonged exposure and virtual reality exposure therapy for posttraumatic stress disorder.

OBJECTIVE: A key symptom of posttraumatic stress disorder (PTSD) is hyperreactivity to trauma-relevant stimuli. Though physiological arousal is reliably elevated in PTSD, the question remains whether this arousal responds to treatment. Virtual reality (VR) has been posited to increase emotional engagement during prolonged exposure therapy (PE) for PTSD by augmenting imaginal exposures with trauma-relevant sensory information. However, the comparative effects of VR exposure therapy (VRE) have received limited empirical inquiry. METHOD: Ninety active-duty soldiers with combat-related PTSD participating in a randomized-controlled trial to receive PE, VRE, or a waitlist-control (WL) condition had their physiological reactivity, indexed by galvanic skin response (GSR), to their trauma memories assessed at pre-, mid-, and posttreatment. RESULTS: Although both VRE and PE conditions showed reduced GSR reactivity to trauma memories from pre- to posttreatment, only the VRE group differed significantly from WL. Across the sample, reductions in GSR were significantly correlated with reductions in self-reported PTSD and anxiety symptoms. CONCLUSIONS: This was the first study comparing effects of VRE and PE on psychophysiological variables. Given previous research finding limited differences between VRE and PE in PTSD symptom reduction, these findings lend support to the rationale for including VR in exposure therapy protocols while raising important questions about the potential benefits of VRE.

The impact of prolonged exposure on sleep and enhancing treatment outcomes with evidence-based sleep interventions: A pilot study.

OBJECTIVE: Insomnia and nightmares are central features of posttraumatic stress disorder (PTSD). However, often they are inadequately assessed and ineffectively resolved following gold-standard PTSD treatment. Here we: (a) evaluate effects of prolonged exposure (PE) on subjectively measured sleep and (b) present pilot results of an examination of whether adding sleep interventions (imagery rehearsal therapy [IRT] and cognitive-behavioral therapy for insomnia [CBT-I]) to PE improves treatment response, relative to PE alone, for night- and/or daytime PTSD symptoms among returning U.S. veterans and postdeployment personnel. METHOD: In a parallel-groups, randomized controlled trial, participants received 12 sessions of PE followed by IRT (5 weeks) and CBT-I (7 weeks) or PE followed by 12 weeks supportive care therapy (SCT). RESULTS: PE did not improve sleep to a clinically meaningful degree, despite significant improvements in both Clinical Administered PTSD Scale and PTSD Checklist. Enhancing treatment with IRT/CBT-I led to greater improvements in insomnia (diary-recorded sleep efficiency) symptoms with large effect size, relative to SCT (p = .068, d = 1.07). There were large improvements in nightmare frequency relative SCT that did not reach statistical significance (p = .11, d = 0.90). Moreover, there was small improvement in daytime symptoms (Clinical Administered PTSD Scale) that did not reach statistical significance (p = .54, d = .31). CONCLUSION: The addition of targeted, validated sleep treatment improves effects of PE and improves nighttime symptoms. Thus, evidence-based sleep treatment should be considered in comprehensive PTSD treatment. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Hurst Rehabilitated: the treatment of functional motor disorders by Arthur Hurst during the First World War.

Arthur Hurst was a British First World War physician, best known for his films of shell shock, 'War Neuroses'. He has often been portrayed an innovative pioneer of somewhat mysterious 'suggestion' techniques for functional motor disorders but also as an ambitious clinician who exaggerated the effectiveness of his treatments and failed to address psychological factors. His use of suggestion, persuasion and re-education together with occupational therapy, for chronic or severe cases of shell shock stirred controversy at the time because of the dramatic nature of some of his treatment responses and lack of outcome data. In part, this was a turf war between neurologists and psychiatrists for a dominant therapeutic model. A re-evaluation of his publications and new research into soldiers treated at Seale Hayne in Devon show that Hurst pioneered multidisciplinary and empathetic treatments for functional motor disorders with good short-term outcomes, though insufficient data survives to assess longer term outcomes.

Traumatic shock and electroshock: the difficult relationship between anatomic pathology and psychiatry in the early 20th century.

In the conviction that a look at the past can contribute to a better understanding of the present in the field of science too, we discuss here two aspects of the relationship between early 20th century anatomic pathology and psychiatry that have received very little attention, in Italy at least. There was much debate between these two disciplines throughout the 19th century, which began to lose momentum in the early years of the 20th, with the arrival on the scene of schizophrenia (a disease histologically sine materia) in all its epidemiological relevance.The First World War also contributed to the separation between psychiatry and pathology, which unfolded in the fruitless attempts to identify a histopathological justification for the psychological trauma known as shell shock. This condition was defined at the time as a "strange disorder" with very spectacular symptoms (memory loss, trembling, hallucinations, blindness with no apparent organic cause, dysesthesias, myoclonus, bizarre postures, hemiplegia, and more), that may have found neuropathological grounds only some hundred years later.Among the doctors with a passed involvement in the conflict, Ugo Cerletti, the inventor of electroshock treatment, focused on the problem of schizophrenia without abandoning his efforts to identify its organic factors: if inducing a controlled electric shock, just like an experimentally-induced epileptic seizure, seems to allay the psychotic symptoms and heal the patient, then what happens inside the brain? In seeking histological proof of the clinical effects of electroconvulsive therapy ("the destruction of the pathological synapses"), and attempting to isolate molecules (that he called acroagonins) he believed to be synthesized by neurons exposed to strong electric stimulation, Cerletti extended a hand towards anatomic pathology, and took the first steps towards a neurochemical perspective. However his dedication to finding a microscopic explanation for schizophrenia - in the name of a "somatist" approach that, some years earlier, the psychiatrist Enrico Morselli had labelled "histomania" - was unable to prevent psychiatry from moving further and further away from anatomic pathology.

Enhancing Completion of Cognitive Processing Therapy for Posttraumatic Stress Disorder with Quetiapine in Veterans with Mild Traumatic Brain Injury: a Case Series.

To evaluate the outcomes of the antiarousal medications valproate, risperidone, and quetiapine on completion of treatment of cognitive processing therapy (CPT) for PTSD. A case series of fifty treatment-seeking adult (≥18 years) veterans with mild traumatic brain injury and combat-related PTSD who had unsuccessful trials of 2 or more first-line agents and previously declined treatment with trauma-focused therapy, seen at the psychiatric outpatient services of the local Polytrauma Rehabilitation Center from January 1, 2014, through December 31, 2017. Patients were prescribed valproate (n = 8), risperidone (n = 17), or quetiapine (n = 25) and were referred for individual weekly treatment with CPT. Outcome measurements of interest were measures of engagement and completion rate of CPT, PTSD Checklist total score (range, 0-80; higher scores indicate greater PTSD severity) and arousal subscale score (range, 0-24; higher scores indicate greater arousal severity), and clinical observations of sleep variables. Of the 50 patients included in the study, 48 (96%) were men; mean (SD) age was 36 (8) years. Eighteen (86%) patients initially receiving quetiapine and none taking valproate or risperidone became adequately engaged in and completed CPT. Among patients who completed CPT, the mean decrease in the PTSD Checklist score was 25 [95% CI, 30 to 20] and 9 (50%) patients no longer met criteria for PTSD. These preliminary findings support quetiapine as an adjunctive medication to facilitate CPT. A pragmatic trial is needed to evaluate the efficacy, safety, and feasibility of quetiapine to improve engagement in and completion rate of CPT.

Predictors of Consent to Treatment and Premature Termination of Treatment in a Sample of Veterans With Military-Related PTSD.

This study examined different variables as predictors of treatment entry and treatment dropout among veterans with military-related posttraumatic stress disorder (PTSD). First, we examined predictors of treatment entry versus refusal of treatment. Among the veterans who started therapy, we examined predictors of treatment completion. Symptom severity of PTSD, depression, and anxiety at baseline were measured. Daily functioning at baseline was also measured. Results indicate that the younger the veterans were, the more likely they were to refuse treatment. Dropout from treatment was also predicted by younger age at referral, as well as by past treatment, higher number of years of education, and higher depression levels at baseline. Two conclusions can be drawn from the results. First, it may be beneficial to increase awareness of treatment options for PTSD among younger veterans as this may increase treatment consent rates. Second, to reduce treatment dropout in veteran patients with PTSD, therapists should take into consideration both past treatment and baseline depression levels as risk factors for dropout.

What Do Veterans Want? Understanding Veterans' Preferences for PTSD Treatment Delivery.

INTRODUCTION: Home-based delivery of psychotherapy may offer a viable alternative to traditional office-based treatment for post-traumatic stress disorder (PTSD) by overcoming several barriers to care. Little is known about patient perceptions of home-based mental health treatment modalities. This study assessed veterans' preferences for treatment delivery modalities and how demographic variables and trauma type impact these preferences. MATERIALS AND METHODS: Veterans with PTSD (N = 180) participating in a randomized clinical trial completed a clinician-administered PTSD assessment and were asked to identify their modality preference for receiving prolonged exposure: home-based telehealth (HBT), office-based telehealth (OBT), or in-home-in-person (IHIP). Ultimately, modality assignment was randomized, and veterans were not guaranteed their preferred modality. Descriptive statistics were used to examine first choice preference. Chi-square tests determined whether there were significant differences among first choice preferences; additional tests examined if age, sex, and military sexual trauma (MST) history were associated with preferences. RESULTS: The study includes 135 male veterans and 45 female veterans from all military branches; respondents were 46.30 years old, on average. Veterans were Caucasian (46%), African-American (28%), Asian-American (9%), American Indian or Alaskan Native (3%), Native Hawaiian or Pacific Islander (3%), and 11% identified as another race. Veterans experienced numerous trauma types (e.g., combat, sexual assault), and 29% had experienced MST. Overall, there was no clear preference for one modality: 42% of veterans preferred HBT, 32% preferred IHIP, and 26% preferred OBT. One-sample binomial tests assuming equal proportions were conducted to compare each pair of treatment options. HBT was significantly preferred over OBT (p = 0.01); there were no significant differences between the other pairs. A multinomial regression found that age group significantly predicted veterans' preferences for HBT compared to OBT (odds ratio [OR] = 10.02, 95% confidence interval [CI]: 1.63, 61.76). Older veterans were significantly more likely to request HBT compared to OBT. Veteran characteristics did not differentiate those who preferred IHIP to OBT. Because there were fewer women (n = 45), additional multinomial regressions were conducted on each sex separately. There was no age group effect among the male veterans. However, compared to female Veterans in the younger age group, older female Veterans were significantly more likely to request HBT over OBT (OR = 10.66, 95% CI: 1.68, 67.58, p = 0.012). MST history did not predict treatment preferences in any analysis. CONCLUSIONS: Fewer than 50% of the sample preferred one method, and each modality was preferred by at least a quarter of all participants, suggesting that one treatment modality does not fit all. Both home-based care options were desirable, highlighting the value of offering a range of options. The use of home-based care can expand access to care, particularly for rural veterans. The current study includes a diverse group of veterans and increases our understanding of how they would like to receive PTSD treatment. The study used a forced choice preference measure and did not examine the strength of preference, which limits conclusions. Future studies should examine the impact of modality preferences on treatment outcomes and engagement.

A systematic review of the psychosocial impact of emotional numbing in US combat veterans.

CONTEXT: Previous studies have linked posttraumatic emotional numbing symptoms in US combat veterans with an adverse impact in multiple important life domains. OBJECTIVES: We updated and evaluated the evidence examining the psychosocial impact of combat-related emotional numbing, including ethnoracial and gender differences. METHOD: We reviewed 1,209 articles published betwen January 2012 and 2018 and selected 24 studies for inclusion. We assessed the overall study quality as fair using a national quality assessment tool. RESULTS: Studies found emotional numbing to wield adverse effects in the areas of symptom nonimprovement, mental health difficulties, increased service utilization, poor relationship functioning, reduced quality of life, substance use disorders, suicidality, and aggression/violence. We also found evidence of ethnoracial and gender differences in veterans' posttraumatic stress disorder-related emotional numbing symptoms. CONCLUSION: Clinicians should incorporate findings on emotional numbing into assessment, treatment planning, and monitoring, to improve treatment retention and psychosocial outcomes. Implications for ethnoracial and gender differences require further exploration.

Provider perspectives on a novel moral injury treatment for veterans: Initial assessment of acceptability and feasibility of the Impact of Killing treatment materials.

OBJECTIVE: We assessed whether treatment providers specializing in evidence-based treatment for posttraumatic stress disorder found the Impact of Killing (IOK), a novel treatment for moral injury among combat veterans, acceptable, and feasible. METHODS: Ten providers from a large veterans administration (VA) medical center were provided with materials from IOK. We audio-recorded a semistructured interview with each provider where we elicited open-ended feedback as well as asked five structured questions about the relative advantage, compatibility, complexity/simplicity, trialability, and observability of IOK. RESULTS: All providers found IOK feasible, acceptable, and something they could incorporate into their existing practice. Providers reported that the spiritual and moral concerns addressed in IOK were novel, and that self-forgiveness and making amends were critical components promoting healing from moral injury not emphasized in other treatments. CONCLUSIONS: Among trauma providers, IOK was found acceptable and feasible, offering a novel approach to addressing moral injury among combat veterans.

Psychiatric Care of the Post-September 11 Combat Veteran: A Review.

BACKGROUND: Post-September 11, 2001 combat veterans represent a growing cohort of patients with unique mental health needs, particularly around post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). The United States (US) remains engaged in conflicts around the globe, so this patient cohort will continue to grow in number. With around 40% of American combat veterans from Iraq and Afghanistan seeking mental health care outside of the Veterans Affairs, understanding the psychiatric needs of the post-September 11 combat veteran is an important goal for all psychiatrists. These patients are relevant to consultation-liaison (C-L) psychiatrists because of their high comorbidity of conditions such as TBI, obstructive sleep apnea, insomnia, and chronic pain. This article reviews the current literature on mental health care for the post-September 11 combat veteran, emphasizing PTSD and TBI treatment, and culling evidence-based recommendations from randomized controlled trials of combat veterans. Emphasis is also placed on the Veterans Affairs/Department of Defense Clinical Practice Guidelines. The authors also bring unique clinical expertise of having served on active duty as psychiatrists for the US Army, including in a combat zone, and both currently work in a Veterans Affairs Iraq and Afghanistan combat veteran mental health clinic. OBJECTIVE: This review outlines useful treatment approaches for PTSD and TBI and briefly covers the comorbid conditions of major depression, chronic pain, and substance use disorders. This review will prepare C-L psychiatrists to care for this challenging patient cohort.
