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.

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.

HIGHLIGHTSWe review studies that examine pre‐treatment biomarkers predicting PTSD psychotherapy outcomes.Brain activity and structures, endocrine processes, and genetics predicted treatment response.Pre‐treatment biomarkers involved with fear learning and extinction predicted treatment outcomes.Biomarkers involved with cogntitive and emotional processing predicted treatment outcomes.Future PTSD clinical outcome research should continue to incorporate biological markers. ABSTRACT Although our understanding of the relationship between posttraumatic stress disorder (PTSD), brain structure and function, neural networks, stress‐related systems, and genetics is growing, there is considerably less attention given to which biological markers predict evidence‐based PTSD psychotherapy outcomes. Our systematic PRISMA‐informed review of 20 studies examined biomarkers as predictors of evidence‐based PTSD psychotherapy outcomes. Results provide preliminary evidence that specific structural and functional neural systems (involved in information processing), glucocorticoid sensitivity and metabolism (part of the hypothalamic–pituitary–adrenal axis and the response to stress), heart rate (involved with fear habituation), gene methylation, and certain genotypes (associated with serotonin and glucocorticoids) predicted positive response to PTSD treatment. These pre‐treatment biomarkers are associated with processes integral to PTSD treatment, such as those affecting fear learning and extinction, cognitive restructuring, information processing, emotional processing, and interoceptive monitoring. Identifying pre‐treatment biomarkers that predict treatment response may offer insight into the mechanisms of psychological treatment, provide a foundation for improving the pharmaceutical augmentation of treatment, and inform treatment matching.

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.

Examining Insomnia and PTSD Over Time in Veterans in Residential Treatment for Substance Use Disorders and PTSD

Peter J. Colvonen; Jennifer Ellison; Moira Haller; Sonya B. Norman

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.

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 (&bgr; = .44, p < .001) and guilt-related distress (&bgr; = .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 (&khgr;2 = 14.22, p < .001), guilt-related distress (&khgr;2 = 15.09, p < .001), and guilt cognitions (&khgr;2 = 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.

Piloting cognitive–behavioral therapy for insomnia integrated with prolonged exposure.

Peter J. Colvonen; Sean P. A. Drummond; Abigail C. Angkaw; Sonya B. Norman

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.

Recent Advancements in Treating Sleep Disorders in Co-Occurring PTSD

Peter J. Colvonen; Laura D. Straus; Carl Stepnowsky; Michael McCarthy; Lizabeth A. Goldstein; Sonya B. Norman

Purpose of ReviewComorbidity 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 FindingsPTSD 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.SummaryTargeted 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.
