Self-reported sleep problems in active-duty US Army personnel receiving posttraumatic stress disorder treatment in group or individual formats: secondary analysis of a randomized clinical trial.

STUDY OBJECTIVES: Sleep disturbances are common in military personnel with posttraumatic stress disorder (PTSD) and may persist following treatment. This study examined service members seeking treatment for PTSD, reporting insomnia symptoms, nightmares, excessive daytime sleepiness, and potential obstructive sleep apnea at baseline and the impact of sleep disturbances on a course of PTSD treatment. METHODS: In this secondary analysis, sleep was evaluated in 223 service members who participated in a randomized clinical trial comparing Cognitive Processing Therapy for PTSD delivered in individual or group formats. Sleep assessments included the Insomnia Severity Index, the Trauma-Related Nightmare Survey, and Epworth Sleepiness Scale administered at baseline and 2 weeks posttreatment. RESULTS: Following PTSD treatment, there were significant improvements for insomnia symptoms (MΔ = -1.49; d = -0.27), nightmares (MΔ = -0.35; d = -0.27), and excessive daytime sleepiness (MΔ = -0.91; d = -0.16). However, mean scores remained in clinical ranges at posttreatment. Participants with baseline insomnia symptoms had worse PTSD severity throughout treatment. Participants with baseline excessive daytime sleepiness or probable obstructive sleep apnea had greater PTSD severity reductions when treated with Cognitive Processing Therapy individually vs. in a group. Those with insomnia symptoms, nightmare disorder, and sleep apnea had greater depressive symptoms throughout treatment. CONCLUSIONS: Insomnia symptoms, nightmares, and excessive daytime sleepiness were high at baseline in service members seeking treatment for PTSD. While sleep symptoms improved with PTSD treatment, these sleep disorders were related to worse treatment outcomes with regards to symptoms of PTSD and depression. Individual Cognitive Processing Therapy is recommended over group Cognitive Processing Therapy for patients with either excessive daytime sleepiness or probable obstructive sleep apnea.

Barriers and Potential Solutions to Implementing Evidence-Based PTSD Treatment in Military Treatment Facilities.

INTRODUCTION: Prolonged exposure therapy is an effective treatment for posttraumatic stress disorder that is underutilized in health systems, including the military health system. Organizational barriers to prolonged exposure implementation have been hypothesized but not systematically examined. This multisite project sought to identify barriers to increasing the use of prolonged exposure across eight military treatment facilities and describe potential solutions to addressing these barriers. MATERIALS AND METHODS: As part of a larger project to increase the use of prolonged exposure therapy in the military health system, we conducted a needs assessment at eight military treatment facilities. The needs assessment included analysis of clinic administrative data and a series of stakeholder interviews with behavioral health clinic providers, leadership, and support staff. Key barriers were matched with potential solutions using a rubric developed for this project. Identified facilitators, barriers, and potential solutions were summarized in a collaboratively developed implementation plan for increasing prolonged exposure therapy tailored to each site. RESULTS: There was a greater than anticipated consistency in the barriers reported by the sites, despite variation in the size and type of facility. The identified barriers were grouped into four categories: time-related barriers, provider-related barriers, barriers related to patient education and matching patients to providers, and scheduling-related barriers. Potential solutions to each barrier are described. CONCLUSIONS: The findings highlight the numerous organizational-level barriers to implementing evidence-based psychotherapy in the military health system and offer potential solutions that may be helpful in addressing the barriers.

Testing the role of aerobic exercise in the treatment of posttraumatic stress disorder (PTSD) symptoms in U.S. active duty military personnel: a pilot study.

The purpose of this pilot study was to determine if the efficacy of imaginal exposure for symptoms of posttraumatic stress disorder (PTSD) could be improved by adding aerobic exercise. We hypothesized that aerobic exercise would enhance the efficacy of exposure therapy. Active duty service members with clinically significant symptoms of posttraumatic stress (PTSD Checklist-Stressor-Specific Version, [PCL-S], ≥25) were randomized into one of four conditions: exercise only; imaginal exposure only; imaginal exposure plus exercise; no exercise/no exposure therapy (control). Participants (N = 72) were primarily male, Army, noncommissioned officers ranging in age from 22 to 52. PTSD symptom severity decreased over time (p < .0001); however, there were no significant differences between the experimental conditions. The prediction that imaginal exposure augmented with aerobic exercise would be superior to either imaginal exposure alone or aerobic exercise alone was not supported, suggesting that engaging in exercise and imaginal exposure simultaneously may not be any better than engaging in either activity alone. A better understanding of individually administered and combined exercise and exposure therapy interventions for PTSD is warranted.

STRONG STAR and the Consortium to Alleviate PTSD: Shaping the future of combat PTSD and related conditions in military and veteran populations.

The STRONG STAR Consortium (South Texas Research Organizational Network Guiding Studies on Trauma and Resilience) and the Consortium to Alleviate PTSD are interdisciplinary and multi-institutional research consortia focused on the detection, diagnosis, prevention, and treatment of combat-related posttraumatic stress disorder (PTSD) and comorbid conditions in military personnel and veterans. This manuscript outlines the consortia's state-of-the-science collaborative research model and how this can be used as a roadmap for future trauma-related research. STRONG STAR was initially funded for 5 years in 2008 by the U.S. Department of Defense's (DoD) Psychological Health and Traumatic Brain Injury Research Program. Since the initial funding of STRONG STAR, almost 50 additional peer-reviewed STRONG STAR-affiliated projects have been funded through the DoD, the U.S. Department of Veterans Affairs (VA), the National Institutes of Health, and private organizations. In 2013, STRONG STAR investigators partnered with the VA's National Center for PTSD and were selected for joint DoD/VA funding to establish the Consortium to Alleviate PTSD. STRONG STAR and the Consortium to Alleviate PTSD have assembled a critical mass of investigators and institutions with the synergy required to make major scientific and public health advances in the prevention and treatment of combat PTSD and related conditions. This manuscript provides an overview of the establishment of these two research consortia, including their history, vision, mission, goals, and accomplishments. Comprehensive tables provide descriptions of over 70 projects supported by the consortia. Examples are provided of collaborations among over 50 worldwide academic research institutions and over 150 investigators.

Identifying suicidal subtypes and dynamic indicators of increasing and decreasing suicide risk in active duty military personnel: Study protocol.

OBJECTIVES: Several recent studies have demonstrated that posttraumatic stress disorder (PTSD) and insomnia treatments are associated with significant reductions in suicidal ideation (SI) among service members. However, few investigations have evaluated the manner in which suicide risk changes over time among military personnel receiving PTSD or insomnia treatments. This paper describes the study protocol for a project with these aims: (1) explore potential genetic, clinical, and demographic subtypes of suicide risk in a large cohort of deployed service members; (2) explore subtype change in SI as a result of evidence-based psychotherapies for PTSD and insomnia; (3) evaluate the speed of change in suicide risk; and (4) identify predictors of higher- and lower-risk for suicide. METHODS: Active duty military personnel were recruited for four clinical trials (three for PTSD treatment and one for insomnia treatment) and a large prospective epidemiological study of deployed service members, all conducted through the South Texas Research Organizational Network Guiding Studies on Trauma and Resilience (STRONG STAR Consortium). Participants completed similar measures of demographic and clinical characteristics and subsets provided blood samples for genetic testing. The primary measures that we will analyze are the Beck Scale for Suicide Ideation, Beck Depression Inventory, and the PTSD Checklist for DSM-IV. DISCUSSION: Results from this study will offer new insights into the presence of discrete subtypes of suicide risk among active duty personnel, changes in risk over time among those subtypes, and predictors of subtypes. Findings will inform treatment development for military service members at risk for suicide.

Predictors of Cognitive Behavioral Therapy for Insomnia (CBTi) Outcomes in Active-Duty U.S. Army Personnel.

Cognitive behavioral therapy for insomnia (CBTi) is well established as the first-line treatment for the management of chronic insomnia. Identifying predictors of response to CBTi should enable the field to efficiently utilize resources to treat those who are likely to respond and to personalize treatment approaches to optimize outcomes for those who are less likely to respond to traditional CBTi. Although a range of studies have been conducted, no clear pattern of predictors of response to CBTi has emerged. The purpose of this study was to examine the impact and relative importance of a comprehensive group of pretreatment predictors of insomnia outcomes in 99 active-duty service members who received in-person CBTi in a randomized clinical trial. Results indicated that higher levels of baseline insomnia severity and total sleep time predicted greater improvements on the Insomnia Severity Index (ISI) following treatment. Higher depression symptoms and a history of head injury predicted a worse response to treatment (i.e., smaller improvements on the ISI). Clinically meaningful improvements, as measured by the reliable change index (RCI), were found in 59% of the sample. Over and above baseline insomnia severity, only depressive symptoms predicted this outcome. Future studies should examine if modifications to CBTi based on these predictors of response can improve outcomes.

Targeted Assessment and Context-Tailored Implementation of Change Strategies (TACTICS) to increase evidence based psychotherapy in military behavioral health clinics: Design of a cluster-randomized stepped-wedge implementation study.

BACKGROUND: Despite efforts by the U.S. Department of Defense to train behavioral health (BH) providers in evidence-based psychotherapies (EBPs) for posttraumatic stress disorder (PTSD), numerous barriers limit EBP implementation. A context-tailored implementation approach called TACTICS (Targeted Assessment and Context-Tailored Implementation of Change Strategies) holds promise for increasing the use of EBPs such as prolonged exposure therapy (PE) in military treatment facilities. TACTICS combines a needs assessment, a rubric for selecting implementation strategies based on local barriers, an implementation toolkit, and external facilitation to support local champions and their implementation teams in enacting changes. This paper describes the rationale for and design of a study that will evaluate whether TACTICS can increase implementation of PE for PTSD and improve patient outcomes in military BH clinics relative to provider training in PE alone. METHODS: The study is a multi-site, cluster randomized, stepped-wedge trial, with the military treatment facility as the unit of analysis. Eight facilities undergo a provider-training phase, followed by 5 months of TACTICS implementation. The timing of TACTICS at each facility is randomly assigned to begin 9, 14, or 19 months after beginning the provider-training phase. Primary analyses will compare the proportion of PTSD patients receiving PE and patients' mean improvement in PTSD symptoms before and after the onset of TACTICS. DISCUSSION: TACTICS endeavors to balance standardization of empirically-supported implementation strategies with the flexibility of application necessary for success across varied clinical settings. If successful, TACTICS may represent a systematic and scalable method of promoting and supporting EBP implementation. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT03663452.

Impact of cognitive behavioral therapy for insomnia disorder on sleep and comorbid symptoms in military personnel: a randomized clinical trial.

Study Objectives: To compare the efficacy of cognitive behavioral therapy for insomnia (CBTi) disorder and a Control condition on reducing insomnia and comorbid symptoms in a sample of active duty military personnel. Methods: Randomized clinical trial of 151 active duty US Army personnel at Fort Hood, Texas. Results: This study replicated Original (n = 66) findings (CBTi outperformed Control) in a follow-on sample (n = 85) on diary-assessed sleep efficiency (d = 1.04), total sleep time (d = 0.38), sleep latency (d = -0.93), number of awakenings (d = -0.56), wake time after sleep onset (d = -0.91), sleep quality (d = 1.00), and the Insomnia Severity Index (d = -1.36) in active duty soldiers. CBTi also outperformed Control in the combined sample (N = 151) on four of the five subscales of the Multidimensional Fatigue Inventory (d = -0.32 to -0.96) and the mental health subscale on the Veterans RAND 12-Item Health Survey (d = 0.37). Exploratory analyses also showed CBTi outperformed Control on nicotine (d = -0.22) and caffeine (d = -0.47) use reduction. Significant within-group differences were found for both groups on depression, anxiety, and posttraumatic stress disorder symptoms, but there was no group by time interaction for these symptoms or for use of hypnotics or alcohol. Conclusions: CBTi was an effective treatment for insomnia and comorbid symptoms including daytime fatigue, general mental health, nicotine, and caffeine use.

The Influence of Posttraumatic Stress Disorder on Health Functioning in Active-Duty Military Service Members.

Researchers have suggested that posttraumatic stress disorder (PTSD) is associated with significant healthcare burden and utilization of medical services. The purpose of this study was to examine the impact of PTSD symptoms on health functioning among active-duty military personnel. Participants in the study were 366 treatment-seeking service members who had returned from deployment and were participating in a larger PTSD treatment study. Assessments included measures of PTSD symptom severity, combat experiences, life stress, health functioning, alcohol use, and depression. We hypothesized that at baseline, PTSD severity and its symptom clusters would be significantly associated with poorer physical and mental health functioning. We conducted separate hierarchical multiple regressions to examine the predictive contribution the hypothesized factors would have on the variance in physical and mental health scores. Consistent with previous literature, we found that PTSD severity was significantly associated with poorer mental health functioning, B = -0.25, SE = 0.08, ß = -0.15, t(342) = -3.07, R2 = .37, p = .002; however, contrary to our hypotheses, PTSD severity was not associated with poorer physical health functioning. Further, the hyperarousal symptom cluster was significantly associated with poorer physical health functioning, B = -0.83, SE = 0.26, ß = -0.18, t(340) = -3.16, R2 = .11, p = .002, but not mental health functioning. Limitations of our study included the use of self-report measures only and lack of objective measures. Future directions for study include examination of how health functioning perceptions change over a longer duration of PTSD symptoms and after treatment.

Reliability of the Structured Clinical Interview for DSM-5 Sleep Disorders Module.

STUDY OBJECTIVES: To develop and demonstrate interrater reliability for a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) Sleep Disorders (SCISD). METHODS: The SCISD was designed to be a brief, reliable, and valid interview assessment of adult sleep disorders as defined by the DSM-5. A sample of 106 postdeployment active-duty military members seeking cognitive behavioral therapy for insomnia in a randomized clinical trial were assessed with the SCISD prior to treatment to determine eligibility. Audio recordings of these interviews were double-scored for interrater reliability. RESULTS: The interview is 8 pages long, includes 20 to 51 questions, and takes 10 to 20 minutes to administer. Of the nine major disorders included in the SCISD, six had prevalence rates high enough (ie, n ≥ 5) to include in analyses. Cohen kappa coefficient (κ) was used to assess interrater reliability for insomnia, hypersomnolence, obstructive sleep apnea hypopnea (OSAH), circadian rhythm sleep-wake, nightmare, and restless legs syndrome disorders. There was excellent interrater reliability for insomnia (1.0) and restless legs syndrome (0.83); very good reliability for nightmare disorder (0.78) and OSAH (0.73); and good reliability for hypersomnolence (0.50) and circadian rhythm sleep-wake disorders (0.50). CONCLUSIONS: The SCISD is a brief, structured clinical interview that is easy for clinicians to learn and use. The SCISD showed moderate to excellent interrater reliability for six of the major sleep disorders in the DSM-5 among active duty military seeking cognitive behavioral therapy for insomnia in a randomized clinical trial. Replication and extension studies are needed.

Effect of Prolonged Exposure Therapy Delivered Over 2 Weeks vs 8 Weeks vs Present-Centered Therapy on PTSD Symptom Severity in Military Personnel: A Randomized Clinical Trial.

Importance: Effective and efficient treatment is needed for posttraumatic stress disorder (PTSD) in active duty military personnel. Objective: To examine the effects of massed prolonged exposure therapy (massed therapy), spaced prolonged exposure therapy (spaced therapy), present-centered therapy (PCT), and a minimal-contact control (MCC) on PTSD severity. Design, Setting, and Participants: Randomized clinical trial conducted at Fort Hood, Texas, from January 2011 through July 2016 and enrolling 370 military personnel with PTSD who had returned from Iraq, Afghanistan, or both. Final follow-up was July 11, 2016. Interventions: Prolonged exposure therapy, cognitive behavioral therapy involving exposure to trauma memories/reminders, administered as massed therapy (n = 110; 10 sessions over 2 weeks) or spaced therapy (n = 109; 10 sessions over 8 weeks); PCT, a non-trauma-focused therapy involving identifying/discussing daily stressors (n = 107; 10 sessions over 8 weeks); or MCC, telephone calls from therapists (n = 40; once weekly for 4 weeks). Main Outcomes and Measures: Outcomes were assessed before and after treatment and at 2-week, 12-week, and 6-month follow-up. Primary outcome was interviewer-assessed PTSD symptom severity, measured by the PTSD Symptom Scale-Interview (PSS-I; range, 0-51; higher scores indicate greater PTSD severity; MCID, 3.18), used to assess efficacy of massed therapy at 2 weeks posttreatment vs MCC at week 4; noninferiority of massed therapy vs spaced therapy at 2 weeks and 12 weeks posttreatment (noninferiority margin, 50% [2.3 points on PSS-I, with 1-sided α = .05]); and efficacy of spaced therapy vs PCT at posttreatment. Results: Among 370 randomized participants, data were analyzed for 366 (mean age, 32.7 [SD, 7.3] years; 44 women [12.0%]; mean baseline PSS-I score, 25.49 [6.36]), and 216 (59.0%) completed the study. At 2 weeks posttreatment, mean PSS-I score was 17.62 (mean decrease from baseline, 7.13) for massed therapy and 21.41 (mean decrease, 3.43) for MCC (difference in decrease, 3.70 [95% CI,0.72 to 6.68]; P = .02). At 2 weeks posttreatment, mean PSS-I score was 18.03 for spaced therapy (decrease, 7.29; difference in means vs massed therapy, 0.79 [1-sided 95% CI, -∞ to 2.29; P = .049 for noninferiority]) and at 12 weeks posttreatment was 18.88 for massed therapy (decrease, 6.32) and 18.34 for spaced therapy (decrease, 6.97; difference, 0.55 [1-sided 95% CI, -∞ to 2.05; P = .03 for noninferiority]). At posttreatment, PSS-I scores for PCT were 18.65 (decrease, 7.31; difference in decrease vs spaced therapy, 0.10 [95% CI, -2.48 to 2.27]; P = .93). Conclusions and Relevance: Among active duty military personnel with PTSD, massed therapy (10 sessions over 2 weeks) reduced PTSD symptom severity more than MCC at 2-week follow-up and was noninferior to spaced therapy (10 sessions over 8 weeks), and there was no significant difference between spaced therapy and PCT. The reductions in PTSD symptom severity with all treatments were relatively modest, suggesting that further research is needed to determine the clinical importance of these findings.

Cognitive Emotion Regulation Strategies Associated With the DSM-5 Posttraumatic Stress Disorder Criteria.

Maladaptive cognitive emotion regulation strategies have been proposed to contribute to the maintenance of posttraumatic stress disorder (PTSD). Prior work has focused on the relationship between these strategies and PTSD as a whole, rather than on how they are related to each PTSD symptom cluster. The purpose of the current study was to determine whether cognitive emotion regulation strategies are predictive of certain PTSD symptom clusters under the Diagnostic and Statistical Manual of Mental Disorders 5th ed. (DSM-5; American Psychiatric Association, 2013) criteria (intrusive thoughts, avoidance, negative alterations in cognitions and mood, and hyperarousal). Participants included 365 treatment-seeking, active-duty military personnel with PTSD. The negative alterations in cognitions and mood cluster were associated with dysfunctional cognitions: greater negative cognitions about the self, negative cognitions about the world, and self-blame, as well as catastrophizing (Rc2 = .519). The negative alterations in cognitions and mood cluster did not show a strong relationship with blaming others, possibly due to the complex nature of self- and other-blame in this primarily deployment-related PTSD sample. Finally, the intrusive thoughts cluster was associated with catastrophizing (Rc2 = .211), suggesting an association between frequent intrusive memories and excessively negative interpretation of those memories.

Ethnoracial differences in PTSD symptoms and trauma-related cognitions in treatment-seeking active duty military personnel for PTSD.

OBJECTIVE: It is uncertain whether ethnoracial factors should be considered by clinicians assessing and treating posttraumatic stress disorder (PTSD) among service members. The purpose of this study was to shed light on ethnoracial variation in the presentation of PTSD symptoms, trauma-related cognitions, and emotions among treatment-seeking active duty military personnel. METHOD: Participants were 303 male active duty military members with PTSD participating in a clinical trial (60% were self-identified as White, 19% as African American, and 21% as Hispanic/Latino). In the parent study, participants completed a baseline assessment that included clinician-administered and self-report measures of PTSD, trauma-related cognitions, and emotions. RESULTS: Multivariate hierarchical regression models were used to examine ethnoracial differences in these variables, covarying age, education, military grade, combat exposure, and exposure to other potentially traumatic events. Hispanic/Latino and African American participants reported more reexperiencing symptoms, more fear, and more guilt and numbing than White participants. All effect sizes were in the small to medium range. CONCLUSIONS: These findings suggest ethnoracial variation in PTSD symptom burden and posttraumatic cognitions among treatment-seeking service members with PTSD. Attending to cultural factors related to differences in PTSD presentation and cognitive coping strategies during the assessment and treatment process could increase rapport and lead to more comprehensive trauma processing.

Effect of Group vs Individual Cognitive Processing Therapy in Active-Duty Military Seeking Treatment for Posttraumatic Stress Disorder: A Randomized Clinical Trial.

IMPORTANCE: Cognitive processing therapy (CPT), an evidence-based treatment for posttraumatic stress disorder (PTSD), has not been tested as an individual treatment among active-duty military. Group CPT may be an efficient way to deliver treatment. OBJECTIVE: To determine the effects of CPT on PTSD and co-occurring symptoms and whether they differ when administered in an individual or a group format. DESIGN, SETTING, AND PARTICIPANTS: In this randomized clinical trial, 268 active-duty servicemembers consented to assessment at an army medical center from March 8, 2012, to September 23, 2014, and were randomized to group or individual CPT. Inclusion criteria were PTSD after military deployment and stable medication therapy. Exclusion criteria consisted of suicidal or homicidal intent or psychosis. Data collection was completed on June 15, 2015. Analysis was based on intention to treat. INTERVENTIONS: Participants received CPT (the version excluding written accounts) in 90-minute group sessions of 8 to 10 participants (15 cohorts total; 133 participants) or 60-minute individual sessions (135 participants) twice weekly for 6 weeks. The 12 group and individual sessions were conducted concurrently. MAIN OUTCOMES AND MEASURES: Primary measures were scores on the Posttraumatic Symptom Scale-Interview Version (PSS-I) and the stressor-specific Posttraumatic Stress Disorder Checklist (PCL-S); secondary measures were scores on the Beck Depression Inventory-II (BDI-II) and the Beck Scale for Suicidal Ideation (BSSI). Assessments were completed by independent evaluators masked to treatment condition at baseline and 2 weeks and 6 months after treatment. RESULTS: Among the 268 participants (244 men [91.0%]; 24 women [9.0%]; mean [SD] age, 33.2 [7.4] years), improvement in PTSD severity at posttreatment was greater when CPT was administered individually compared with the group format (mean [SE] difference on the PSS-I, -3.7 [1.4]; Cohen d = 0.6; P = .006). Significant improvements were maintained with the individual (mean [SE] PSS-I, -7.8 [1.0]; Cohen d = 1.3; mean [SE] PCL-S, -12.6 [1.4]; Cohen d = 1.2) and group (mean [SE] PSS-I, -4.0 [0.97]; Cohen d = 0.7; mean [SE] PCL-S, -6.3 [1.4]; Cohen d = 0.6) formats, with no differences in remission or severity of PTSD at the 6-month follow-up. Symptoms of depression and suicidal ideation did not differ significantly between formats. CONCLUSIONS AND RELEVANCE: Individual treatment resulted in greater improvement in PTSD severity than group treatment. Depression and suicidal ideation improved equally with both formats. However, even among those receiving individual CPT, approximately 50% still had PTSD and clinically significant symptoms. In the military population, improving existing treatments such as CPT or developing new treatments is needed. TRIAL REGISTRATION: clinicaltrials.gov identifier: NCT02173561.

Residual sleep disturbances following PTSD treatment in active duty military personnel.

OBJECTIVE: Sleep disturbances, including nightmares and insomnia, are frequently reported symptoms of posttraumatic stress disorder (PTSD). Insomnia is one of the most common symptoms to persist after evidence-based PTSD treatment. The purpose of this study was to examine the prevalence of sleep disturbances in a sample of active duty military personnel before and after receiving therapy for PTSD in a clinical trial and to explore the associations of insomnia and nightmares with PTSD diagnosis after treatment. METHOD: Sleep parameters were evaluated with the PTSD Checklist in 108 active duty U.S. Army soldiers who had completed at least one deployment in support of the wars in Iraq and Afghanistan and who participated in a randomized clinical trial comparing Group Cognitive Processing Therapy-Cognitive Only Version with Group Present-Centered Therapy. RESULTS: Insomnia was the most frequently reported symptom before and after treatment, with 92% reporting insomnia at baseline and 74%-80% reporting insomnia at follow-up. Nightmares were reported by 69% at baseline and by 49%-55% at follow-up. Among participants who no longer met criteria for PTSD following treatment, 57% continued to report insomnia, but only 13% continued to report nightmares. At baseline, 54% were taking sleep medications, but sleep medication use did not affect the overall results. CONCLUSIONS: Insomnia was found to be one of the most prevalent and persistent problems among service members receiving PTSD treatment. Nightmares were relatively more positively responsive to treatment. For some service members with PTSD, the addition of specific treatments targeting insomnia and/or nightmares may be indicated.

Qualitative examination of cognitive change during PTSD treatment for active duty service members.

The current study investigated changes in service members' cognitions over the course of Cognitive Processing Therapy (CPT) for posttraumatic stress disorder (PTSD). Sixty-three active duty service members with PTSD were drawn from 2 randomized controlled trials of CPT-Cognitive Only (CPT-C). Participants wrote an impact statement about the meaning of their index trauma at the beginning and again at the end of therapy. Clauses from each impact statement were qualitatively coded into three categories for analysis: assimilation, accommodation, and overaccommodation. The PTSD Checklist, Posttraumatic Symptom Scale-Interview Version, and the Beck Depression Inventory-II were administered at baseline and posttreatment. Repeated measures analyses documented a significant decrease in the percentage of assimilated or overaccommodated statements and an increase in the percentage of accommodated statements from the beginning to the end of treatment. Changes in accommodated statements over the course of treatment were negatively associated with PTSD and depression symptom severity, while statements indicative of overaccommodation were positively associated with both PTSD and depression symptom severity. Treatment responders had fewer overaccommodated and more accommodated statements. Findings suggest that CPT-C changes cognitions over the course of treatment. Methodological limitations and the lack of association between assimilation and PTSD symptom severity are further discussed.

Regional cerebral glucose metabolism differentiates danger- and non-danger-based traumas in post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is presumably the result of life threats and conditioned fear. However, the neurobiology of fear fails to explain the impact of traumas that do not entail threats. Neuronal function, assessed as glucose metabolism with (18)fluoro-deoxyglucose positron emission tomography, was contrasted in active duty, treatment-seeking US Army Soldiers with PTSD endorsing either danger- (n = 19) or non-danger-based (n = 26) traumas, and was compared with soldiers without PTSD (Combat Controls, n = 26) and Civilian Controls (n = 24). Prior meta-analyses of regions associated with fear or trauma script imagery in PTSD were used to compare glucose metabolism across groups. Danger-based traumas were associated with higher metabolism in the right amygdala than the control groups, while non-danger-based traumas associated with heightened precuneus metabolism relative to the danger group. In the danger group, PTSD severity was associated with higher metabolism in precuneus and dorsal anterior cingulate and lower metabolism in left amygdala (R(2 )= 0.61). In the non-danger group, PTSD symptom severity was associated with higher precuneus metabolism and lower right amygdala metabolism (R(2 )= 0.64). These findings suggest a biological basis to consider subtyping PTSD according to the nature of the traumatic context.

A randomized clinical trial of group cognitive processing therapy compared with group present-centered therapy for PTSD among active duty military personnel.

OBJECTIVE: To determine whether group therapy improves symptoms of posttraumatic stress disorder (PTSD), this randomized clinical trial compared efficacy of group cognitive processing therapy (cognitive only version; CPT-C) with group present-centered therapy (PCT) for active duty military personnel. METHOD: Patients attended 90-min groups twice weekly for 6 weeks at Fort Hood, Texas. Independent assessments were administered at baseline, weekly before sessions, and 2 weeks, 6 months, and 12 months posttreatment. A total of 108 service members (100 men, 8 women) were randomized. Inclusion criteria included PTSD following military deployment and medication stability. Exclusion criteria included suicidal/homicidal intent or other severe mental disorders requiring immediate treatment. Follow-up assessments were administered regardless of treatment completion. Primary outcome measures were the PTSD Checklist (Stressor Specific Version; PCL-S) and Beck Depression Inventory-II. The Posttraumatic Stress Symptom Interview (PSS-1) was a secondary measure. RESULTS: Both treatments resulted in large reductions in PTSD severity, but improvement was greater in CPT-C. CPT-C also reduced depression, with gains remaining during follow-up. In PCT, depression only improved between baseline and before Session 1. There were few adverse events associated with either treatment. CONCLUSIONS: Both CPT-C and PCT were tolerated well and reduced PTSD symptoms in group format, but only CPT-C improved depression. This study has public policy implications because of the number of active military needing PTSD treatment, and demonstrates that group format of treatment of PTSD results in significant improvement and is well tolerated. Group therapy may an important format in settings in which therapists are limited.

Implementation outcomes of military provider training in cognitive processing therapy and prolonged exposure therapy for post-traumatic stress disorder.

Between 2006 and 2012, the Department of Defense trained thousands of military mental health providers in the use of evidence-based treatments for post-traumatic stress disorder. Most providers were trained in multiday workshops that focused on the use of Cognitive Processing Therapy and Prolonged Exposure. This study is a follow-up evaluation of the implementation practices of 103 Air Force mental health providers. A survey was administered online to workshop participants; 34.2% of participants responded. Findings on treatment implementation with the providers indicated that a majority of respondents found the trainings valuable and were interested in using the treatments, yet they reported a lack of time in their clinic appointment structure to support their use. Insufficient supervision was also cited as a barrier to treatment use. Results suggest the need to improve strategies for implementing evidence-based practices with providers to enhance clinical outcomes in military settings.

Assessment and treatment of combat-related PTSD in returning war veterans.

Over the past 9 years approximately 2 million U.S. military personnel have deployed in support of Operation Iraqi Freedom in Iraq and Operation Enduring Freedom in and around Afghanistan. It has been estimated that 5-17% of service members returning from these deployments are at significant risk for combat-related posttraumatic stress disorder (PTSD). Many of these returning war veterans will seek medical and mental health care in academic health centers. This paper reviews the unique stressors that are related to the development of combat-related PTSD. It also reviews evidence-based approaches to the assessment and treatment of PTSD, research needed to evaluate treatments for combat-related PTSD, and opportunities and challenges for clinical psychologists working in academic health centers.
