The Posttraumatic Stress Disorder Checklist (PCL-5; Weathers et al., 2013) was recently revised to reflect the changed diagnostic criteria for posttraumatic stress disorder (PTSD) in the fifth ...edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). We investigated the psychometric properties of PCL-5 scores in a large cohort (N = 912) of military service members seeking PTSD treatment while stationed in garrison. We examined the internal consistency, convergent and discriminant validity, and DSM-5 factor structure of PCL-5 scores, their sensitivity to clinical change relative to PTSD Symptom Scale-Interview (PSS-I; Foa, Riggs, Dancu, & Rothbaum, 1993) scores, and their diagnostic utility for predicting a PTSD diagnosis based on various measures and scoring rules. PCL-5 scores exhibited high internal consistency. There was strong agreement between the order of hypothesized and observed correlations among PCL-5 and criterion measure scores. The best-fitting structural model was a 7-factor hybrid model (Armour et al., 2015), which demonstrated closer fit than all other models evaluated, including the DSM-5 model. The PCL-5's sensitivity to clinical change, pre- to posttreatment, was comparable with that of the PSS-I. Optimally efficient cut scores for predicting PTSD diagnosis were consistent with prior research with service members (Hoge, Riviere, Wilk, Herrell, & Weathers, 2014). The results indicate that the PCL-5 is a psychometrically sound measure of DSM-5 PTSD symptoms that is useful for identifying provisional PTSD diagnostic status, quantifying PTSD symptom severity, and detecting clinical change over time in PTSD symptoms among service members seeking treatment.

Soumoff et al. (2021) reported on a sample of 2,217 injured military service members and found that somatic symptom severity was more predictive of the development of probable posttraumatic stress ...disorder (PTSD) symptoms than injury severity. PTSD has been described as one of the invisible wounds of war, suggesting that many military service members with PTSD may suffer in silence because some symptoms—such as psychological and somatic symptoms—are often not observable by others. In contrast, friends, family, fellow service members, and health care providers often ask military service members with visible, physical wounds what happened, prompting a discussion of their injury and the events that contributed to it. I posit that the findings reported by Soumoff et al. may be an example of the differences that can occur in the course of natural recovery in military service members suffering from visible versus invisible wounds of war and further hypothesize that the repeated conversations that often occur after physical injuries in military service members may foster natural recovery from the co‐occurring invisible, psychological wounds of war.

Dropout from first-line posttraumatic stress disorder (PTSD) treatments is a significant problem. We reported rates and predictors of attendance and dropout in three clinical trials of evidence-based ...PTSD treatments in military service members (N = 557). Service members attended 81.0% of treatment sessions and 30.7% dropped out. Individually delivered treatment was associated with greater attendance rates (β = 0.23, p < .001) than group therapy; trauma-focused treatments were associated with higher dropout (β = 0.19, p < .001) than Present-Centered Therapy. Age was a significant predictor of session attendance (β = 0.17, p < .001) and drop out (β = −0.23, p < .001). History of traumatic brain injury (TBI) predicted lower attendance rates (β = −0.26, p < .001) and greater dropout (β = 0.19, p < .001). Regardless of treatment type or format, patients who did not drop out were more likely to experience clinically significant gains (d = 0.49, p < .001). Results demonstrate that dropout from PTSD treatments in these trials was significantly associated with treatment outcome and suggest that strategies are needed to mitigate dropout, particularly in group and trauma-focused therapies, and among younger service members and those with TBI.
•Predictors of service members' PTSD treatment attendance and dropout were examined.•Dropout from therapy for military-related PTSD is a problem in clinical trials.•Strategies to mitigate dropout should target group and trauma-focused therapies.

ABSTRACT
It has been 20 years since the September 11, 2001 terrorist attacks on America. The ongoing military conflicts in this region are the longest sustained conflicts in U.S. history. Almost 3 ...million military personnel have deployed, with over 7,000 fatalities and more than 53,000 wounded in action. The most common psychological health condition associated with combat deployments is PTSD. No data exist to compare the prevalence of PTSD across war eras. Therefore, a potential proxy for PTSD risk is the number of combat-related deaths, because this figure has been consistently tracked across U.S. military conflicts. This commentary includes a table of death statistics from major military conflicts, which shows that fewer military personnel have deployed, been killed, sustained wounds, and, one might conclude, suffered from PTSD than any other major U.S. military conflict in history. Advances in the military equipment, tactics, and healthcare programs perhaps mitigated casualties and suffering among Iraq/Afghanistan veterans compared to previous wars. The estimated causality differences across various military conflicts are not meant to minimize the significant contributions and sacrifices made by this new generation of military warriors but to help us gain perspective on military conflicts over the past century as we recognize the 20th anniversary of 9/11.

Posttraumatic stress disorder (PTSD) is a pervasive issue within military populations, with approximately 29 % of post-9/11 service members experience PTSD at some point in their lifetime. One ...potentially important factor in PTSD development and treatment response is dysregulation of the stress response system stemming from exposure to multiple traumas and sustained operational stress associated with military training and deployment. In particular, the end-product of the hypothalamic-pituitary-adrenal (HPA) axis, cortisol, is of particular interest to researchers examining physiological stress response in the context of mental health. Research exploring cortisol has been ongoing for decades, both to further understand its pathways and mechanisms, and to develop potential novel PTSD treatments. This paper provides a narrative review of some of the published literature examining cortisol’s role in PTSD as a potential factor in development, maintenance, and treatment augmentation, with emphasis on military populations. The results of this review highlight the importance of exploring alterations to the stress response system, and cortisol in particular, for the evaluation and treatment of PTSD in the military, the need for more comprehensive work towards understanding development of these alterations through military training and service, and its impact on long-term PTSD outcomes.
•Trauma-focused PTSD treatments demonstrate less effectiveness among service members.•Cortisol reactivity has been found to behave differently in military and civilian populations.•One potentially important factor in PTSD development and treatment response is dysregulation of the nervous system.•Service members may have a desensitized stress response due to sustained operational stress.•More work is needed on cortisol and PTSD, specifically in the military population.

OBJECTIVE:To examine moderators and predictors of response to behavior therapy for tics in children and adults with Tourette syndrome and chronic tic disorders.
METHODS:Data from 2 10-week, multisite ...studies (1 in children and 1 in adults; total n = 248) comparing comprehensive behavioral intervention for tics (CBIT) to psychoeducation and supportive therapy (PST) were combined for moderator analyses. Participants (177 male, 71 female) had a mean age of 21.5 ± 13.9 years (range 9–69). Demographic and clinical characteristics, baseline tic-suppressing medication, and co-occurring psychiatric disorders were tested as potential moderators for CBIT vs PST or predictors of outcome regardless of treatment assignment. Main outcomes measures were the Yale Global Tic Severity Scale Total Tic score and the Clinical Global Impression–Improvement score assessed by masked evaluators.
RESULTS:The presence of tic medication significantly moderated response to CBIT vs PST (p = 0.01). Participants showed tic reduction after CBIT regardless of tic medication status, but only participants receiving tic medication showed reduction of tics after PST. Co-occurring psychiatric disorders, age, sex, family functioning, tic characteristics, and treatment expectancy did not moderate response. Across both treatments, greater tic severity (p = 0.005) and positive participant expectancy (p = 0.01) predicted greater tic improvement. Anxiety disorders (p = 0.042) and premonitory urge severity (p = 0.005) predicted lower tic reduction.
CONCLUSIONS:Presence of co-occurring attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, or anxiety disorders did not moderate response to CBIT. Although participants on tic medication showed improvement after CBIT, the difference between CBIT and PST was greater for participants who were not on tic-suppressing medication.
CLINICALTRIALS.GOV IDENTIFIERS:The child and adult CBIT studies are listed on clinical trials.gov (NCT00218777 and NCT00231985, respectively).
CLASSIFICATION OF EVIDENCE:This study provides Class I evidence that CBIT is effective in reducing tic severity across subgroups of patients with chronic tic disorders, although the difference between treatments was smaller for participants on tic-suppressing medications, suggesting reduced efficacy in this subgroup.
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.

ABSTRACT
Few service members with posttraumatic stress disorder (PTSD) receive evidence-based psychotherapy (EBP) in the military health system (MHS). Efforts to increase EBP implementation have ...focused on provider training but have not adequately addressed organizational barriers. Thus, although behavioral health providers are trained in EBPs, clinic-, facility-, and system-level barriers preclude widespread EBP implementation. Building on work examining barriers to EBP use for PTSD across eight military treatment facilities, we propose recommendations for increasing the implementation of EBPs for PTSD and improving the quality of behavioral health care in MHS outpatient behavioral health clinics. Increasing the use of EBPs for PTSD will require that their use is supported and prioritized through MHS policy. We recommend that psychotherapy appointments are scheduled at least once weekly, as clinically indicated, as this frequency of care is prerequisite for EBP delivery. We propose several recommendations designed to increase system capacity for weekly psychotherapy, including improved triaging of potential patients, incentivizing and supporting group psychotherapy, matching the modality (i.e., group vs. individual) and frequency of treatment to patients’ needs, and using behavioral health technicians as clinician extenders. Additional recommendations include providing ongoing support for EBP implementation (e.g., protected time to participate in EBP consultation) and matching patients to providers based on patient’s clinical needs and treatment preferences. The barriers to EBP implementation that these recommendations target are interrelated. Therefore, adopting multiple policy recommendations is likely necessary to yield a meaningful and sustained increase in the implementation of EBPs for PTSD in the MHS.

Abstract
Study Objectives
Epidemiologic studies of obstructive sleep apnea (OSA) and insomnia in the U.S. military are limited. The primary aim of this study was to report and compare OSA and ...insomnia diagnoses in active duty the United States military service members.
Method
Data and service branch densities used to derive the expected rates of diagnoses on insomnia and OSA were drawn from the Defense Medical Epidemiology Database. Single sample chi-square goodness of fit tests and independent samples t-tests were conducted to address the aims of the study.
Results
Between 2005 and 2019, incidence rates of OSA and insomnia increased from 11 to 333 and 6 to 272 (per 10,000), respectively. Service members in the Air Force, Navy, and Marines were diagnosed with insomnia and OSA below expected rates, while those in the Army had higher than expected rates (p < .001). Female service members were underdiagnosed in both disorders (p < .001). Comparison of diagnoses following the transition from ICD 9 to 10 codes revealed significant differences in the amounts of OSA diagnoses only (p < .05).
Conclusion
Since 2005, incidence rates of OSA and insomnia have markedly increased across all branches of the U.S. military. Despite similar requirements for overall physical and mental health and resilience, service members in the Army had higher rates of insomnia and OSA. This unexpected finding may relate to inherent differences in the branches of the military or the role of the Army in combat operations. Future studies utilizing military-specific data and directed interventions are required to reverse this negative trend.
Posttraumatic stress disorder (PTSD) affects approximately 8% of the general population. The prevalence of PTSD is twice as high in active duty service members and military veterans. Few studies have ...investigated the incidence rates of PTSD in active duty military personnel. The present study evaluated the incidence of PTSD diagnoses and the differences between demographic factors for service members between 2001 and 2017. Data on 182,400 active duty service members between 2001 and 2017 were drawn from the Defense Medical Epidemiological Database and examined by sex, age, service branch, military pay grade, marital status, and race. From 2001 to 2017, the incidence rates of PTSD in the active force (per 1,000 service members) steadily climbed, with a low of 1.24 in 2002 to a high of 12.94 in 2016. Service members most often diagnosed with PTSD were in the U.S. Army, with the enlisted pay grades of E‐5–E‐9, White, married, male, and between 20 and 24 years old. Statistically significant differences, ps < .001, were found between observed and expected counts across all examined demographic variables. The present study is the first to our knowledge to provide a comprehensive examination of PTSD incidence rates in an active duty military population.
