RESUMEN
BACKGROUND: The purpose of this study was to assess the prevalence and sequelae of insomnia, obstructive sleep apnea (OSA), and comorbid OSA and insomnia (COMISA). METHOD: In the morning, after a shift end, Midwest career firefighters ( N = 89) in a midsized city completed an electronic battery of questionnaire to screen for OSA, daytime sleepiness, insomnia, presleep arousal, nightmares, mental and physical health symptoms, and a one-night sleep diary. RESULTS: Prevalence of firefighters exceeding screening thresholds: OSA: 54%; insomnia: 30%; COMISA: 17%; four or more nightmares per month: 15%. Firefighters who met criteria for COMISA had shorter total sleep time, less restful and worse sleep quality, higher depression and anxiety symptoms, and presleep arousal symptoms than firefighters without self-reported sleep problems. CONCLUSIONS: Many firefighters are at elevated risk of individual behavioral sleep disorders, COMISA, and daytime dysfunction.

OBJECTIVE: Research suggests that healthy sleep is a key component of sexual function. When evaluating sexual function, however, poor sleep is often overlooked as a contributing factor. This cross-sectional survey expands prior work by exploring relationships among insomnia severity, sexual satisfaction, and sexual function with an updated battery of measures for the Sleep and Sex Survey. METHOD: The sample (N = 1266) consisted of 618 men, 648 women recruited via Prolific, an online survey platform. The Sleep and Sex Survey II included measures addressing insomnia, fear of sleep, nightmares, sexual function, sexual satisfaction, sexual activity, depression, anxiety, posttraumatic stress, and alcohol use. RESULTS: Recent sexual activity was correlated with better sleep, lower anxiety, and lower scores on a posttraumatic stress disorder screener. Insomnia severity was negatively correlated with sexual satisfaction (r = 0.22, p < .001) and the presence of insomnia was associated with higher rates of sexual dysfunction in women (53.8% vs. 31.8%; p < .001) and men (22.7% vs. 12.5%; p = .036). In regression analyses, after accounting for depression and anxiety, insomnia had a statistically significant association with sexual function for women (ß = 0.12; p < .01) but not men (ß = 0.11; p = .60). CONCLUSION: Findings support a relationship of insomnia to sexual function and satisfaction with some gender differences. Future work may be enhanced by assessing these relationships in a gender diverse population including objective sleep measures and addressing contributing mechanisms. Clinically, findings support the assessment of sleep when evaluating patients for sexual dysfunction.

In the past three-and-a-half decades, nearly 500 randomized controlled trials (RCTs) have examined Acceptance and Commitment Therapy (ACT) for a range of health problems, including depression. However, emerging concerns regarding the replicability of scientific findings across psychology and mental health treatment outcome research highlight a need to re-examine the strength of evidence for treatment efficacy. Therefore, we conducted a metascientific review of the evidential value of ACT in treating depression. Whereas reporting accuracy was generally high across all trials, we found important differences in evidential value metrics corresponding to the types of control conditions used. RCTs of ACT compared to weaker controls (e.g., no treatment, waitlist) were well-powered, with sample sizes appropriate for detecting plausible effect sizes. They typically yielded stronger Bayesian evidence for (and larger posterior estimates of) ACT efficacy, though there was some evidence of significance inflation among these effects. RCTs of ACT against stronger controls (e.g., other psychotherapies), meanwhile, were poorly powered, designed to detect implausibly large effect sizes, and yielded ambiguous-if not contradicting-Bayesian evidence and estimates of efficacy. Although our review supports a view of ACT as efficacious for treating depression compared to weaker controls, future RCTs must provide more transparent reporting with larger groups of participants to properly assess the difference between ACT and competitor treatments such as behavioral activation and other forms of cognitive behavioral therapy. Clinicians and health organizations should reassess the use of ACT for depression if costs and resources are higher than for other efficacious treatments.

OBJECTIVE: Posttrauma nightmares are recurring nightmares that begin after a traumatic experience. Research has only recently begun to identify variables that predict posttrauma nightmare occurrences. Research has identified presleep arousal-cognitive (PSA-C) and presleep arousal physiological (PSA-PHYS), sleep onset latency (SOL), and sleep-disordered breathing (SDB) as potential predictors of posttrauma nightmares. However, previous research includes methodological limitations, such as a lack of physiological measures and a homogeneous sample. To replicate previous findings and increase generalizability, the current study investigated predictors of nightmare occurrences in a sample of male inpatient veterans with mixed-trauma history. METHOD: Participants (n = 15) completed an initial assessment battery and seven consecutive days of pre and postsleep diaries, including measures of posttrauma nightmare triggers and posttrauma nightmare occurrences. Portable objective measurements of sleep and presleep states were used to examine sleep quality and physical arousal. RESULTS: Analyses revealed that PSA-C and SOL both predicted posttrauma nightmare occurrences and that PSA-PHYS was significantly higher on nights when nightmares occurred. CONCLUSION: Results replicate earlier research which posits that PSA and SOL play a role in triggering the occurrence of posttrauma nightmares. It should be noted that the sample was relatively small, warranting cautious interpretation of results. However, when taken together with the findings of the replicated study, results could suggest the plausibility of therapies targeting presleep cognitions, SOL, and presleep arousal in the treatment of posttrauma nightmares.

RESUMEN
STUDY OBJECTIVES: This study's objective was to evaluate the effect of nightmares (NMs) on attrition and symptom change following cognitive behavioral therapy for insomnia (CBT-I) treatment using data from a successful CBT-I randomized controlled trial delivered to participants with recent interpersonal violence exposure. METHODS: The study randomized 110 participants (107 women; mean age: 35.5 years) to CBT-I or to an attention-control group. Participants were assessed at 3 time periods: baseline, post-CBT-I (or attention control), and at time 3 (T3) post-cognitive processing therapy received by all participants. NM reports were extracted from the Fear of Sleep Inventory. Participants with weekly NMs were compared with those with fewer than weekly NMs on outcomes including attrition, insomnia, posttraumatic stress disorder, and depression. Change in NM frequency was examined. RESULTS: Participants with weekly NMs (55%) were significantly more likely to be lost to follow-up post-CBT-I (37%) compared with participants with infrequent NMs (15.6%) and were less likely to complete T3 (43%) than patients with less frequent NMs (62.5%). NMs were unrelated to differential treatment response in insomnia, depression, or posttraumatic stress disorder. Treatment with CBT-I was not associated with reduced NM frequency; however, change in sleep-onset latency from post-CBT-I to T3 predicted fewer NMs at T3. CONCLUSIONS: Weekly NMs were associated with attrition but not a reduced change in insomnia symptoms following CBT-I. NM symptoms did not change as a function of CBT-I, but change in sleep-onset latency predicted lower NM frequency. CBT-I trials should screen for NMs and consider augmenting CBT-I to specifically address NMs. CITATION: Hamilton NA, Russell JA, Youngren WA, et al.

The Posttraumatic Checklist for Civilians (PCL-C) is one of the most common tools used to assess PTSD among civilian populations. However, the underlying factor structure of the PCL-C remains under examined, with the most recent research relying on small samples with limited generalizability. Thus, the present study used exploratory and confirmatory techniques in a large North American college student sample to investigate the factor structure of the PCL-C. Results supported a 3-factor model for the PCL-C accounting for 59% of the total variance and represented by Suppression (M = 11.2, SD = 5.0); Hyperarousal (M = 6.5, SD = 3.2); and Diminished Reward Processing (M = 5.9, SD = 2.9). Regarding gender differences, females tended to score higher on suppression and avoidance related symptoms, while males scored higher on symptoms related to Diminished Reward Processing. Results also showed that embedded within college campuses are trauma exposed students experiencing distressingly high levels of posttrauma symptoms. In sum, the results revealed three factors in the PCL-C, that could be used to offer insight into assessing and treating posttrauma symptoms on a college campus.
RESUMEN
Research is mixed on the role of service era in symptom endorsement among Veterans, with differences emerging depending on the instrument evaluated. This study compares Personality Assessment Inventory (PAI) scale scores of VA test-takers who served during the Vietnam, Desert Storm, or Post-9/11 service eras. The sample was collected at a VA Posttraumatic Stress Disorder Clinical Team. Associations between gender and combat exposure were also examined as covariates. Results suggest that Veterans' self-report on the PAI is influenced by service era, even after accounting for gender and combat exposure during deployment. The largest differences were between Vietnam or Post-9/11 Veterans and those from the Gulf War era. Symptom differences typically varied across scales commonly associated with symptoms of trauma exposure/posttraumatic stress disorder. Implications for the clinical use of, and research with, the PAI and other broadband personality assessments within the VA healthcare system and trauma treatment settings are discussed.

This investigation utilized a large sample of individuals undergoing substance use treatment to examine the CES-D's structural validity and establish its predictive utility relative to treatment discharge. The sample included 5750 individuals who were receiving substance abuse treatment at 19 different residential treatment facilities. The CES-D was administered to participants over the course of their time in a residential inpatient substance use treatment program. The present study used a split sample method to conduct both exploratory (EFA) and confirmatory (CFA) factor analyses. Results of both the EFA and CFA indicated that the CES-D contains three first order factors measuring negative mood, positive affect, and interpersonal interactions as well as a second-order high score factor which can be used to guide interpretation and symptom monitoring. Individuals receiving residential treatment fell into one of three distinct groups based on their CES-D scores, and that their scores (and subsequent trajectories of scores over time) were differentially related to discharge status. Implications for practice and the utility of the CES-D within substance use populations are discussed.

Posttrauma nightmares are recurring nightmares that begin after a traumatic experience and can occur as often as multiple times per week, often in a seemingly random pattern. Although these nightmares are prevalent in trauma survivors, little is known about the mechanisms underlying their sporadic occurrence. The present study aimed to investigate predictors of posttrauma nightmares. The sample included 146 observations nested within 27 female college students who reported frequent nightmares related to sexual trauma. Participants were recruited from an undergraduate student subject pool (n = 71) or were clinical referrals (n = 75). Participants completed an initial assessment battery and six consecutive days of pre- and postsleep diaries, which included measures of potential posttrauma nightmare triggers and measures intended to assess sleep quality and posttrauma nightmare occurrence. Descriptive statistics, mean comparisons, and multilevel modeling were used to examine the data. The results showed that both presleep cognitive arousal, γ10 SLij = 0.58, p = .006, z(1, N = 146) = -2.61; and sleep latency (SL), γ20 PCAij = 0.76, p < .001, z(1, N = 146) = -2.69, predicted posttrauma nightmare occurrence. Further investigation suggested that presleep cognitive arousal moderated the relation between SL and posttrauma nightmare occurrence, γ30 PCA x SLij = 0.67, p = .048 z(1, N = 146) = 1.98. The present results are the first to show that the co-occurrence of presleep arousal and delayed sleep onset latency may influence posttrauma nightmare occurrence, suggesting that the time immediately before sleep is crucial to the production of the posttrauma nightmares.

Sleep disorders are frequently under assessed and not well understood by medical practitioners. This study investigated medical practitioners' knowledge of, experience with, and treatment considerations for sleep disorders, with a particular emphasis on nightmares. Eighty-eight individuals practicing medicine in the United States completed a survey eliciting information in three domains: (a) professional experience with nightmares, (b) knowledge of nightmares, and (c) attitudes about treatment of sleep disturbances. Seventy percent of participants reported a lack of professional experience with nightmares, 78% endorsed inaccurate definitions of a nightmares, and 82% considered sleep disorders to be a secondary problem, with 75% considering nightmares a secondary problem. Seventy-two percent of participants reported they would be likely to consider psychological treatment for nightmares. Results suggest that medical practitioners may not be receiving updated and/or adequate education about sleep disorders, including nightmares. This lack of information may contribute to sleep disorders being under assessed and untreated.

BACKGROUND: Prior cognitive research in posttraumatic stress disorder (PTSD) has focused on automatic responses to negative affective stimuli, including attentional facilitation or disengagement and avoidance action tendencies. More recent research suggests PTSD may also relate to differences in reward processing, which has lead to theories of PTSD relating to approach-avoidance imbalances. The current pilot study assessed how combat-PTSD symptoms relate to automatic behavioral tendencies to both positive and negative affective stimuli. METHOD: Twenty male combat veterans completed the approach-avoidance task (AAT), Clinician Administered PTSD Scale, Beck Depression Inventory-II, and State-Trait Anger Expression Inventory-II. During the AAT, subjects pulled (approach) or pushed (avoid) a joystick in response to neutral, happy, disgust, and angry faces based on border color. Bias scores were calculated for each emotion type (avoid-approach response latency differences). Main and interaction effects for psychological symptom severity and emotion type on bias score were assessed using linear mixed models. RESULTS: There was a significant interaction between PTSD symptoms and emotion type, driven primarily by worse symptoms relating to a greater bias to avoid happy faces. Post hoc tests revealed that veterans with worse PTSD symptoms were slower to approach as well as quicker to avoid happy faces. Neither depressive nor anger symptoms related to avoid or approach tendencies of emotional stimuli. CONCLUSION: Posttraumatic stress disorder severity was associated with a bias for avoiding positive affective stimuli. These results provide further evidence that PTSD may relate to aberrant processing of positively valenced, or rewarding stimuli. Implicit responses to rewarding stimuli could be an important factor in PTSD pathology and treatment. Specifically, these findings have implications for recent endeavors in using computer-based interventions to influence automatic approach-avoidance tendencies.
