Abstract
OBJECTIVE Prolonged exposure (PE) is an effective treatment for posttraumatic stress disorder (PTSD), but veterans with sexual assault (SA) trauma often discontinue it prematurely. Elevated dropout rates may be due to SA triggering more intense and complex emotions that are more difficult to habituate during imaginal exposures; SA during PE has yet to be examined as a moderator of distress habituation or symptom reduction. METHOD Participants were N = 65 veterans (n = 12 SA treatment focus; n = 10 SA history but not treatment focus; n = 43 no SA history) enrolled in a clinical trial of a preparatory sleep intervention followed by PE. The sample was representative of the veteran population. Growth curve modeling was used to examine differences in peak subjective units of distress scale (SUDS) ratings across imaginal exposures and changes in biweekly PTSD symptom assessments between veterans who did versus did not focus on SA during PE and between veterans who did versus did not endorse a history of SA. RESULTS Peak SUDS ratings and PTSD symptoms declined slower among veterans who focused on an SA trauma relative to those who did not. In contrast, participants who endorsed SA history showed similar declines in distress and PTSD symptoms relative to veterans with no SA history. CONCLUSIONS Veterans who focus on SA during PE may take longer to habituate to trauma content and experience resolution of PTSD symptoms. Awareness of this pattern could allow clinicians to deliver PE more effectively to veterans focusing on an SA trauma. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Examining the bidirectional relationship between posttraumatic stress disorder symptom clusters and PAP adherence. J Clin Sleep Med 2023; 19:857-863. [PMID: 36692162 PMCID: PMC10152361 DOI: 10.5664/jcsm.10430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 12/01/2022] [Accepted: 12/01/2022] [Indexed: 01/25/2023]
Abstract
STUDY OBJECTIVES Obstructive sleep apnea (OSA) is a common sleep disturbance in individuals with posttraumatic stress disorder (PTSD), with an emerging literature showing that treating OSA with positive airway pressure (PAP) therapy has a moderate effect on decreasing PTSD severity. Unfortunately, PAP adherence among individuals with PTSD is low. Our study examined how baseline PTSD cluster subscores predict 6-month PAP adherence and how PAP adherence predicts change in PTSD cluster subscores over time. METHODS We examined PTSD and PAP adherence in 41 veterans with PTSD newly diagnosed with OSA over 6 months of PAP use (mean age = 50.27 years; 73.7% White; 13.6% female). The Posttraumatic Stress Disorder Checklist-Specific (PCL-S) was used to examine PTSD and subscales (re-experiencing, avoidance, and hyperarousal). We used longitudinal analyses to examine PTSD subscores on PAP adherence and PAP adherence predicting changes in PTSD subscores at 6-month follow-up. RESULTS Among veterans with PTSD, higher levels of re-experiencing and hyperarousal, but not avoidance, predicted lower PAP use. Overall, the high-adherent group showed a 14.36-point decrease on the PCL-S, while the low-adherent group averaged just a 3.66-point decrease. More days of PAP use were associated with greater improvement in hyperarousal and avoidance subscores but not re-experiencing. CONCLUSIONS Our findings reaffirm the importance of PAP use among patients with comorbid PTSD and sleep apnea, as well as the difficulty in achieving adherent PAP use in this population. Directly addressing heightened re-experiencing and hyperarousal in PTSD may increase PAP adherence among veterans with PTSD and requires future research.

Sleep efficiency predicts improvements in fear extinction and PTSD symptoms during prolonged exposure for veterans with comorbid insomnia. Psychiatry Res 2023; 324:115216. [PMID: 37099850 PMCID: PMC10395069 DOI: 10.1016/j.psychres.2023.115216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 04/03/2023] [Accepted: 04/20/2023] [Indexed: 04/28/2023]
Abstract
Prolonged exposure (PE) is an evidenced-based psychotherapy for PTSD, but many Veterans fail to achieve a clinically meaningful response. Sleep issues are prevalent in Veterans and may interfere with PE by disrupting the learning and consolidation of fear extinction memories during PE exposures. Here, we examined whether changes in fear extinction across imaginal exposures and PTSD symptoms during PE were predicted by diary-assessed levels of nightly sleep efficiency (SE; i.e., percent of time in bed spent sleeping), which may indirectly index sleep fragmentation and sleep-facilitated memory processes. Participants were Veterans with PTSD and comorbid insomnia (N = 40) participating in a clinical trial of cognitive-behavioral therapy for insomnia plus PE. SE was measured via nightly sleep diaries, fear extinction was operationalized as a reduction in peak distress between weekly imaginal exposures, and PTSD symptoms were assessed bi-weekly. Cross-lagged panel models revealed that higher sleep efficiency during the week predicted lower peak distress at the subsequent imaginal exposure and lower PTSD symptoms at the subsequent assessment, whereas PTSD symptoms and peak distress did not predict subsequent sleep efficiency. Efficient sleep may facilitate fear extinction and PTSD reduction during PE. Targeting sleep efficiency could improve PE effectiveness for Veterans with comorbid insomnia.

Pre-deployment threat learning predicts increased risk for post-deployment insomnia: Evidence from the Marine Resiliency Study. Behav Res Ther 2022; 159:104223. [PMID: 36327523 PMCID: PMC9893737 DOI: 10.1016/j.brat.2022.104223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 10/18/2022] [Accepted: 10/21/2022] [Indexed: 02/04/2023]
Abstract
Insomnia is a common and impairing consequence of military deployment, but little is known about pre-deployment risk factors for post-deployment insomnia. Abnormal threat learning tendencies are commonly observed in individuals with insomnia and maladaptive responses to stress have been implicated in the development of insomnia, suggesting that threat learning could be an important risk factor for post-deployment insomnia. Here, we examined pre-deployment threat learning as a predictor of post-deployment insomnia and the potential mechanisms underlying this effect. Male servicemembers (N = 814) completed measures of insomnia, psychiatric symptoms, and a threat learning task before and after military deployment. Threat learning indices that differentiated participants with versus withoutinsomnia at post-deployment were tested as pre-deployment predictors of post-deployment insomnia. Post-deployment insomnia was linked to elevations on several threat learning indices at post-deployment, but only higher threat conditioning, as indexed by higher threat expectancy ratings to the danger cue, emerged as a pre-deployment predictor of post-deployment insomnia. This effect was independent of combat exposure levels and partially mediated by greater post-deployment nightmares. The tendency to acquire stronger expectations of aversive events following encounters with danger cues may increase risk for post-deployment insomnia, in part due to the development of more severe nightmares.

Abstract
BACKGROUND Obstructive sleep apnea (OSA) is often comorbid with both substance use disorders (SUD) and posttraumatic stress disorder (PTSD), yet frequently goes undiagnosed and untreated. We present data on the feasibility and acceptability of objective OSA diagnosis procedures, findings on OSA prevalence, and the relationship between OSA and baseline SUD/PTSD symptoms among veterans in residential treatment for comorbid PTSD/SUD. METHODS Participants were 47 veterans admitted to residential PTSD/SUD treatment. Participants completed questionnaires assessing PTSD and sleep symptoms, and filled out a sleep diary for seven days. Apnea-hypopnea index (AHI) was recorded using the overnight Home Sleep Apnea test (HSAT; OSA was diagnosed with AHI ≥ 5). RESULTS Objective OSA diagnostic testing was successfully completed in 95.7% of participants. Of the 45 veterans who went through HSAT, 46.7% had no OSA, 35.6% received a new OSA diagnosis, and 8.9% were previously diagnosed with OSA and were using positive airway pressure treatment (PAP); an additional 8.9% were previously diagnosed with OSA, reconfirmed with the HSAT, but were not using PAP. One hundred percent of respondents during follow-up deemed the testing protocol's usefulness as "Good" or "Excellent." CONCLUSION OSA diagnostic testing on the residential unit was feasible and acceptable by participants and was effective in diagnosing OSA. OSA testing should be considered for everyone entering a SUD and PTSD residential unit. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

STOP-BANG screener vs objective obstructive sleep apnea testing among younger veterans with PTSD and insomnia: STOP-BANG does not sufficiently detect risk. J Clin Sleep Med 2022; 18:67-73.

Abstract
STUDY OBJECTIVES Posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) cooccur even in veterans who are younger with lower body mass index. The STOP-BANG screener for OSA relies heavily on high blood pressure, age, and body mass index and may not generalize to veterans with PTSD. The inability to effectively screen veterans for OSA is problematic given negative outcomes of untreated OSA. METHODS Our study compared the STOP-BANG to objective OSA diagnostic testing in 48 younger veterans (mean age 43.7 years; 43.8% Caucasian; 20.8% female) seeking treatment for PTSD and insomnia. Apnea-hypopnea events per hour (apnea-hypopnea index), recorded by NOX T3 sleep monitors, were used to diagnose OSA (apnea-hypopnea index ≥ 5 events/h). Logistic regressions examined how STOP-BANG cut-off scores (≥ 3 and ≥ 5) classified OSA status (apnea-hypopnea index ≥ 5 events/h). Follow-up chi-square goodness-of-fit tests examined single-item STOP-BANG performance in the OSA-positive subsample (n = 28). RESULTS The STOP-BANG (≥ 3) had good sensitivity (92.6%) but poor specificity (47.6%) and negative (0.16) and positive (1.77) likelihood ratios. The STOP-BANG (≥ 5) led to improved specificity (76.19%), but sensitivity (37.04%) and positive (1.56)/negative likelihood ratios (0.83) were poor. Single-item OSA subgroup analyses revealed that body mass index, age, and neck circumference performed poorly, while tiredness and sex performed well. CONCLUSIONS Findings suggest that the STOP-BANG correctly diagnosed OSA in some veterans but missed OSA in large number of younger veterans with PTSD. This suggests objective diagnostic OSA testing is needed in veterans with PTSD. Future research is needed to develop more accurate OSA screening measures in this population.

Abstract
STUDY OBJECTIVES Post-9/11 veterans are particularly vulnerable to insomnia disorder. Having accurate prevalence rates of insomnia disorder in this relatively young, diverse population, is vital to determine the resources needed to identify and treat insomnia disorder. However, there are no accurate prevalence rates for insomnia disorder in post-9/11 veterans enrolling in the VA Healthcare System (VHA). We present accurate prevalence of insomnia disorder, and correlates, in a large sample of post-9/11 veterans enrolling in a VHA. METHODS This was an observational study of 5,552 post-9/11 veterans newly enrolling for health care in a VHA. Data were collected using VA eScreening. Insomnia diagnosis was determined using a clinical cutoff score of ≥ 11 on the Insomnia Severity Index. Measures also included sociodemographic, service history, posttraumatic stress disorder (PTSD), depression, suicidal ideation, alcohol misuse, military sexual trauma, traumatic brain injury (TBI), and pain intensity. RESULTS About 57.2% of the sample population had insomnia disorder. Our sample was nationally representative for age, sex, ethnicity, branch of the military, and race. The sample also was at high-risk for a host of clinical disorders, including PTSD, TBI, and pain; all of which showed higher rates of insomnia disorder (93.3%, 77.7%, and 69.6%, respectively). CONCLUSIONS The findings suggest alarmingly high rates of insomnia disorder in this population. Examining and treating insomnia disorder, especially in the context of co-occurring disorders (e.g. PTSD), will be a necessity in the future.

Abstract
Abstract
Introduction
Mental health disorders and sleep disorders are associated with systemic inflammation, which may be a key element linking these highly co-occurring conditions to negative health outcomes. This study used national VA medical records to examine C-reactive protein (CRP) levels in Iraq/Afghanistan veterans based on presence of mental health and/or sleep disorder diagnoses.
Methods
We examined medical records for 16,576 Iraq/Afghanistan veterans under age 55 who had high-sensitivity CRP results reported. ICD diagnostic codes were used to compare CRP values for: a) veterans without sleep disorders or mental health diagnoses, b) veterans with mental health disorders only, c) veterans with sleep disorders only, and d) veterans with both conditions. In generalized linear models controlling for demographics, we examined the impact of diagnostic category on continuous CRP value as well as the risk of elevated CRP (>3mg/L).
Results
Veterans with mental health disorders (coeff=.14, p<.001) and comorbid sleep and mental health disorders (coeff=.21, p<.001) had higher continuous CRP values compared to veterans without either condition. Veterans with comorbid sleep and mental health disorders had higher continuous CRP values than veterans with sleep disorders alone (coeff=.22, p<.041); however, there were few patients in the current sample who were diagnosed with sleep disorders alone (n=401, 2.4%). Additionally, veterans with mental health disorders (ARR=1.12, p=.004) and comorbid sleep and mental health disorders (ARR=1.15, p=.001) were more likely to have CRP values >3mg/L compared to veterans without either condition.
Conclusion
Sleep disorders were highly likely to co-occur with mental health disorders in this sample of Iraq/Afghanistan veterans. Mental health disorders and comorbid mental health/sleep disorders were associated with elevated C-reactive protein, indicating these patients are at highest risk for negative health outcomes. Future studies should investigate directionality of relationships among sleep disruption, mental health symptoms, and inflammation.

Abstract
Abstract
Introduction
Obstructive sleep apnea (OSA) is highly co-occurring with both alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) and has been shown to interfere with both PTSD and AUD outcomes. However, OSA often goes undiagnosed and untreated in residential treatment facilities. Our study aimed to assess the feasibility of incorporating OSA screening and treatment onto a substance abuse residential rehabilitation treatment program (SARRTP). Further, we examine the relationship between adherence rates of CPAP on PTSD outcomes.
Methods
Participants were 35 consecutive veterans admitted to the SARRTP PTSD track who consented to screening. Veterans were on the unit for 4-6 weeks. OSA was diagnosed using Nox T3 recorders, a Type-3 portable OSA screener (using Apnea Hypopnea Index >= 5). Insomnia Severity Index and PTSD checklist were given at pre- and post-treatment.
Results
64.7% of Veterans screened positive for OSA. 11.8% were previously diagnosed with OSA, but did not use a CPAP machine; 17.6% were previously diagnosed and were using a CPAP machine; and 35.3% were newly diagnosed with OSA. Individuals with untreated OSA had significantly more days drinking in the last 30 days (M = 21.17 days, SD = 11.41) compared to no OSA/Treated OSA group (M = 8.82 days, SD = 10.92). There was no difference in change in PCL scores from baseline to post-treatment by the no-OSA/high compliance group and the low compliance group.
Conclusion
Taken together, OSA screening on the unit was accepted by the participants, feasible, and effective in diagnosing OSA. OSA screening and treatment should be considered as necessary on SUD and PTSD units. We did not find that OSA adherence predicted change in PTSD score, this is most likely due to veterans receiving their CPAP late into their stay on the unit. Future studies will need to examine OSA treatment on long term treatment outcomes.

Abstract
Abstract
Introduction
Comorbidity of posttraumatic stress disorder (PTSD) and obstructive sleep apnea (OSA) is staggeringly high, with rates of 75.7% when using criteria of apnea/hyponea index (AHI) > 5. Continuous positive airway pressure (CPAP) therapy can decrease PTSD symptoms, however, no study has used advanced mixed-modeling to examine which cluster of PTSD CPAP therapy effects.
Methods
Participants were 59 veterans with PTSD and undiagnosed OSA. Apnea/Hypopnea index (AHI) was scored according to AASM criteria. Auto-titration CPAP devices were prescribed with pressures empirically selected by the sleep physician based on BMI, overall AHI, and dominant event type; maximum pressures was set at 20cm H2O. Analyses used hierarchical linear modeling to examine changes in PTSD symptoms clusters as a function of CPAP use over 6-months. Measures include PTSD checklist (PCL) and clusters (reexperiencing, avoidance, and hyperarousal), percentage of nights CPAP used, weight, and BMI.
Results
Baseline scores were high: PCL (M=60.02; SD=15.03) and AHI (M=28.18 per hour; SD=20.35). Average number of nights CPAP use in the last 6-months was 59.3%, with 3.5 hours each night with clear adherent and non-adherent groups emerging. The adherent group showed a 15-point drop in PCL scores and the non-adherent group had a 3-point drop. More days of CPAP use in the last 6-months predicted larger decreases in hyperarousal (d=0.56) and re-experiencing (d=0.47)
clusters, but not avoidance. The intercept was significant in the hyperarousal analyses suggesting individuals with higher hyperarousal at baseline had less CPAP adherence.
Conclusion
The need for PTSD clinicians to screen and refer for OSA is necessary, but may not be sufficient, in treating PTSD. Change in hyperarousal symptoms accounted for most of the effects from CPAP use. Higher hyperarousal symptoms at baseline predict lower CPAP adherence, suggesting a higher clinical need to address these individuals as they will get the most positive effects from CPAP.

Abstract
STUDY OBJECTIVES Insomnia is highly co-occurring with both posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). This is concerning since insomnia contributes to worse substance abuse and PTSD, and a host of negative health consequences. No study has tracked how sleep indices and insomnia change related to integrated PTSD and AUD treatment using evidence-based exposure therapy. This study examined how insomnia changes over time in a randomized control trial of two integrated PTSD and AUD treatments. METHODS Participants were 119 adult veterans (90 % male) seeking treatment for AUD and PTSD at a large urban VA. Participants were randomized to either COPE (integrated treatment using prolonged exposure) or Seeking Safety (integrated therapy using cognitive behavioral, interpersonal techniques and case management). Assessments were done at pre- and post-treatment and include: Clinician Administered PTSD Scale, Timeline Follow-back calendar-assisted interview for AU, insomnia severity index (ISI), sleep diary and actigraphy for 7 days. RESULTS ISI showed significant decreases, but a majority remained above the clinical cutoff at post-treatment. Wake after sleep onset decreased, but only by 8 min, remaining above clinical thresholds. Decreases in PTSD, but not in heavy drinking, predicted change in ISI. No significant changes were observed in other sleep variables measured. CONCLUSIONS Findings suggested some statistical improvements in sleep quality, but sleep indices remained above clinical cut-offs. This study provides evidence that insomnia is an independent disorder and not responsive to PTSD or AUD treatments alone. Sleep symptoms should be assessed and treated in patients with comorbid mental health conditions.

Abstract
IMPORTANCE Co-occurrence of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is common and associated with psychiatric and functional problems. Understanding whether exposure therapy is tolerable and efficacious for treating PTSD and AUD is critical to ensure that best practice treatments are available. OBJECTIVE To compare the efficacy of integrated (ie, targeting both PTSD and alcohol use) prolonged exposure (I-PE) therapy with present-centered integrated coping skills (I-CS) therapy, a more commonly available treatment, in reducing PTSD symptoms and alcohol use. DESIGN, SETTING, AND PARTICIPANTS This prospective randomized clinical trial with masked assessments considered 186 veterans seeking Veterans Affairs mental health services. A total of 119 veterans with PTSD and AUD were randomized. Data were collected from February 1, 2013, to May 31, 2017, before treatment, after treatment, and at 3- and 6-month follow-ups. Intention-to-treat analyses were performed. INTERVENTIONS Veterans underwent I-PE (Concurrent Treatment of PTSD and Substance Use Disorder Using Prolonged Exposure) or I-CS (Seeking Safety) therapy. MAIN OUTCOMES AND MEASURES A priori planned outcomes were PTSD symptoms (Clinician Administered PTSD Scale for DSM-5) and percentage of heavy drinking days (Timeline Follow-Back) before treatment, after treatment, and at 3- and 6-month follow-ups. RESULTS A total of 119 veterans (mean [SD] age, 41.6 [12.6] years; 107 [89.9%] male) were randomized. Linear mixture models found that PTSD symptoms decreased in both conditions, with a significantly greater decrease for I-PE treatment compared with I-CS treatment (treatment × time interaction, -2.83; F3,233.1 = 4.92; Cohen d = 0.41; P = .002). The percentage of heavy drinking days improved in both conditions but was not statistically different between I-PE and I-CS treatment (treatment × time interaction, 1.8%; F3,209.9 = 0.18; Cohen d = 0.04; P = .91). CONCLUSIONS AND RELEVANCE The I-PE arm had a greater reduction in PTSD symptoms than the I-CS arm and comparable drinking decreases. The study provides evidence that exposure therapy is more efficacious in treating PTSD than a more commonly available integrated treatment without exposure for comorbid PTSD and AUD.

Abstract
Objective/Background: Insomnia occurs in 66-90% of individuals with posttraumatic stress disorder (PTSD) and 36-72% of individuals with substance use disorder (SUD). Individuals with both PTSD and SUD are more likely to have insomnia than individuals with only one disorder. Insomnia is associated with poorer treatment outcomes for both PTSD and SUD, increased daytime symptomology for PTSD, and increased relapse for SUDs. As such, it is important to understand how sleep affects PTSD treatment among patients dually diagnosed with SUD and how sleep changes over time in a residential unit for SUDs. Participants: Participants were 40 veterans with comorbid PTSD and SUD in a 28-day Substance Abuse Residential Rehabilitation Treatment Program (SARRTP) PTSD track. Methods: Analyses used mixed models with Time (baseline, posttreatment, 3-month follow-up) to examine PTSD and insomnia severity over time. Results: Results of the longitudinal mixed model showed that PTSD symptoms improved over time but that insomnia symptoms did not. Although baseline insomnia did not affect follow-up PTSD symptoms, individuals with greater insomnia severity at the start of treatment had more severe baseline PTSD symptomatology. However, there was not an interaction of insomnia and PTSD severity over time such that baseline insomnia did not affect PTSD trajectories. Conclusions: These findings are consistent with the PTSD outpatient treatment findings and further adds evidence that insomnia is unremitting without direct intervention. Given the relationship insomnia has with PTSD severity, SUD, and relapse, directly targeting insomnia may further help improve both PTSD and SUD treatment outcomes.

Abstract
PURPOSE OF REVIEW The emotional memory and learning model of PTSD posits maladaptive fear conditioning, extinction learning, extinction recall, and safety learning as central mechanisms to PTSD. There is increasingly convincing support that sleep disturbance plays a mechanistic role in these processes. The current review consolidates the evidence on the relationships between emotional memory and learning, disturbed sleep, and PTSD acquisition, maintenance, and treatment. RECENT FINDINGS While disrupted sleep prior to trauma predicts PTSD onset, maladaptive fear acquisition does not seem to be the mechanism through which PTSD is acquired. Rather, poor extinction learning/recall and safety learning seem to better account for who maintains acute stress responses from trauma versus who naturally recovers; there is convincing evidence that this process is, at least in part, mediated by REM fragmentation. Individuals with PTSD had higher "fear load" during extinction, worse extinction learning, poorer extinction recall, and worse safety learning. Evidence suggests that these processes are also mediated by fragmented REM. Finally, PTSD treatments that require extinction and safety learning may also be affected by REM fragmentation. Addressing fragmented sleep or sleep architecture could be used to increase emotional memory and learning processes and thus ameliorate responses to trauma exposure, reduce PTSD severity, and improve treatment. Future studies should examine relationships between emotional memory and learning and disturbed sleep in clinical PTSD patients.

Piloting cognitive-behavioral therapy for insomnia integrated with prolonged exposure. PSYCHOLOGICAL TRAUMA : THEORY, RESEARCH, PRACTICE AND POLICY 2019; 11:107-113.

Abstract
OBJECTIVE Approximately 35-61% of individuals with posttraumatic stress disorder (PTSD) report insomnia. Further, upward of 70% report clinically significant insomnia following PTSD treatment. There are converging lines of evidence suggesting that insomnia not only independently affects daytime functioning and worsens PTSD symptoms but also may compromise response to PTSD treatment, such as prolonged exposure (PE). Taken together, integrated insomnia and PTSD treatment may increase client-centered care and treatment outcomes. METHOD This article reviews the theory and evidence for treating sleep prior to PTSD treatment, describes the key elements of integrated cognitive-behavioral treatment for insomnia (CBT-I) and PE (2NITE protocol), and presents pilot data from a sample of 12 treatment-seeking veterans with PTSD and insomnia who completed the 2NITE protocol. Sleep data were collected with sleep diaries and actigraphy watches. RESULTS The Client Satisfaction Questionnaire indicated high satisfaction with the 2NITE protocol (mean score 29.66 out of 32 points). On average, there were statistical and clinically significant changes in all measures, including a 20.17-point decrease in the PTSD Checklist DSM-5, a 11.75-point decrease in the insomnia severity index, an 18.58-point increase in the World Health Organization Quality of Life index, a 11% increase in sleep efficiency, and a 51-min increase in total sleep time from the actigraphy data. CONCLUSIONS Among individuals with insomnia and PTSD, integrating CBT-I and PE with the 2NITE protocol represents a logical, innovative, and empirically informed method for augmenting existing treatments and optimizing outcomes that justifies further investigation.

Abstract
OBJECTIVE Despite important conceptual differences between shame and guilt, literature distinguishing these emotions in relation to posttrauma functioning for veterans has been largely theoretical. This is the first study to concurrently examine trauma-related guilt and internalized shame in relation to PTSD severity as the dependent variable. Our primary aim was to examine guilt and shame on PTSD symptom severity within the same model. A secondary aim was to evaluate whether trauma-related guilt can occur independent of shame. METHOD Participants were 144 veterans seeking PTSD treatment. Regression analysis was used for our primary aim. Chi-square was used for our secondary aim to examine the percentage of participants categorized one standard deviation above (high) and below (low) the mean for shame and guilt. RESULTS Entered together, internalized shame (β = .44, p < .001) and guilt-related distress (β = .32, p < .001) were related to PTSD severity. Guilt cognitions and global guilt were unrelated to PTSD. Analyses showed significant differences in participants categorized as low/high shame and low/high global guilt (χ² = 14.22, p < .001), guilt-related distress (χ² = 15.09, p < .001), and guilt cognitions (χ² = 13.16, p < .001). Across guilt subscales, "shame-free" trauma-related guilt did not exist (0%). Conclusions Internalized shame and guilt distress were both related to PTSD severity; however, shame added variance not already accounted for by guilt. Tangney, Stuewig, and Mashek (2007) stipulate that guilt becomes maladaptive when fused with shame; however, our results indicate trauma-related guilt is possibly always fused with shame.

Abstract
PURPOSE OF REVIEW Comorbidity of posttraumatic stress disorder (PTSD) and insomnia, nightmares, and obstructive sleep apnea (OSA) is high. We review recent research on psychotherapeutic and pharmacological interventions for sleep disorders in PTSD. RECENT FINDINGS PTSD treatments decrease PTSD severity and nightmare frequency, but do not resolve OSA or insomnia. Research on whether insomnia hinders PTSD treatment shows mixed results; untreated OSA does interfere with PTSD treatment. Cognitive behavioral therapy for insomnia is the recommended treatment for insomnia; however, optimal ordering with PTSD treatment is unclear. PTSD treatment may be most useful for PTSD-related nightmares. CPAP therapy is recommended for OSA but adherence can be low. Targeted treatment of sleep disorders in the context of PTSD offers a unique and underutilized opportunity to advance clinical care and research. Research is needed to create screening protocols, determine optimal order of treatment, and elucidate mechanisms between sleep and PTSD treatments.

Anxiety sensitivity in the association between posttraumatic stress and substance use disorders: A systematic review. Clin Psychol Rev 2018; 62:37-55.

Abstract
Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) are complex psychiatric conditions that commonly co-occur. No evidence-based, "gold standard" treatments for PTSD/SUD comorbidity are currently available. Thus, it is imperative to better understand cognitive-affective mechanisms, targetable via cognitive-behavioral intervention (i.e., malleable), that may be related to both disorders in order to improve the theory and treatment of PTSD/SUD. Anxiety sensitivity is a malleable cognitive-affective factor with relevance to both PTSD and SUD. This systematic review focused on the published literature on anxiety sensitivity and trauma/PTSD and substance use/SUD from 1966 - May 1, 2018, and includes a total of 35 manuscripts. The state of the literature, limitations, and future research directions are discussed.

Abstract
OBJECTIVE Veterans with alcohol use disorder (AUD) and co-occurring posttraumatic stress disorder (PTSD) have access to various residential and outpatient treatment programs through the VA Healthcare System. There is a need to better understand the characteristics and needs of veterans who engage in residential versus outpatient treatment in order to help inform veteran care and decisions about treatment services. METHODS The present study examined whether veterans with both AUD and combat-related PTSD who were enrolled in residential (n = 103) or outpatient treatment programs (n = 76) differed on pretreatment psychiatric symptoms, substance use and associated problems/behaviors, or demographics. Veterans completed self-report measures (which referenced symptoms in the past 30 days or 2 weeks) within the first week of PTSD/AUD treatment. RESULTS Veterans in residential treatment had slightly worse PTSD symptoms compared to outpatient veterans; the groups reported similar levels of depression symptoms. Residential veterans had higher frequency of drug use, were more confident in their ability to be abstinent, attended more self-help meetings, spent more time around risky people or places, were more satisfied with their progress toward recovery goals, were more bothered by arguments with family/friends, and spent fewer days at work or school compared to outpatient veterans; the groups did not differ on drinking (frequency of use, binge drinking) or cravings. With respect to demographics, residential veterans were more likely to be married and non-Hispanic Caucasian (rather than minority races/ethnicities) compared to outpatient veterans. CONCLUSIONS The finding that PTSD symptoms were more severe among veterans in residential substance use treatment highlights the importance of taking advantage of this crucial opportunity to engage veterans in evidence-based PTSD treatment. Consistent with other research, findings also indicated that individuals entering residential care have a higher level of impairment than those beginning outpatient care.

Abstract
STUDY OBJECTIVES There is limited information about prevalence of insomnia in general populations of veterans of recent wars in Iraq and Afghanistan. No studies have examined insomnia in veterans with military sexual trauma (MST). We assess prevalence of insomnia, identify types of services sought by veterans with insomnia, and examine correlates of insomnia in veterans with and without MST. DESIGN A cross-sectional study of first-encounter veterans registering to establish care. SETTING Veteran Affairs San Diego Healthcare System. PARTICIPANTS Nine hundred seventeen veterans completed questionnaires assessing insomnia, MST, service needs, traumatic brain injury, resilience, and symptoms of depression, posttraumatic stress disorder (PTSD), pain, alcohol misuse, and hypomania. INTERVENTIONS N/A. MEASUREMENTS AND RESULTS 53.1% of veterans without MST and 60.8% of veterans with MST had clinically significant insomnia symptoms, with the MST subsample reporting more severe symptoms, P < 0.05. Insomnia was more prevalent than depression, hypomania, PTSD, and substance misuse. Veterans with insomnia were more likely to seek care for physical health problems and primary care versus mental health concerns, P < 0.001. For the veteran sample without MST, age, combat service, traumatic brain injury, pain, and depression were associated with worse insomnia, P < 0.001. For the MST subsample, employment status, pain, and depression were associated with worse insomnia, P < 0.001. CONCLUSIONS Study findings indicate a higher rate of insomnia in veterans compared to what has been found in the general population. Insomnia is more prevalent, and more severe, in veterans with military sexual trauma. Routine insomnia assessments and referrals to providers who can provide evidence-based treatment are crucial.

Obstructive Sleep Apnea and Posttraumatic Stress Disorder among OEF/OIF/OND Veterans. J Clin Sleep Med 2015; 11:513-8.

Abstract
OBJECTIVES This study examined: (a) the relationship between self-reported posttraumatic stress disorder (PTSD) symptoms and risk of obstructive sleep apnea (OSA) in a younger, Iraq and Afghanistan (OEF/OIF/OND) veteran sample seeking treatment for PTSD; and (b) the relationships between PTSD symptom scores and each risk factor of OSA (snoring, fatigue, high blood pressure/BMI). METHODS Participants were 195 Iraq and Afghanistan veterans presenting to a VA outpatient PTSD clinic for evaluation. Veterans were 21 to 59 years old (mean 33.40, SD 8.35) and 93.3% male (n = 182). Logistic regressions were run to examine whether veterans with greater PTSD symptom severity had an increased probability of screening as high risk for OSA, even after controlling for known risk factors (older age, positive smoking status, and use of CNS depressants). RESULTS Of 159 veterans screened, 69.2% were assessed as being at high risk for OSA. PTSD symptom severity increased the risk of screening positive for OSA. PTSD symptom severity increased risk of screening positive for snoring and fatigue, but not high blood pressure/BMI. CONCLUSIONS OEF/OIF/OND veterans with PTSD screen as high risk for OSA at much higher rates than those seen in community studies and may not show all classic predictors of OSA (i.e., older and higher BMI). This study is the first to suggest that the Berlin may be a useful screener for OSA in a younger OEF/OIF/OND veteran population with PTSD. Screening of younger veterans with PTSD for OSA should be standard care, and polysomnography and OSA interventions should be readily available to younger veterans.
