AimsTo examine whether cognitive behavioral therapy for insomnia (CBT-I), delivered by telephone, improves sleep and non-sleep symptoms of Gulf War Illness (GWI).Main methodsEighty-five Gulf War veterans (21 women, mean age: 54 years, range 46-72 years) who met the Kansas GWI case definition, the Centers for Disease Control and Prevention (CDC) case definition for Chronic Multisymptom Illness (CMI), and research diagnostic criteria for insomnia disorder were randomly assigned to CBT-I or monitor-only wait list control. Eight weekly sessions of individual CBT-I were administered via telephone by Ph.D. level psychologists to study participants. Outcome measures included pre-, mid-, and post-treatment assessments of GWI and insomnia symptoms, subjective sleep quality, and continuous sleep monitoring with diary. Outcomes were re-assessed 6-months post-treatment in participants randomized to CBT-I.Key findingsCompared to wait list, CBT-I produced significant improvements in overall GWI symptom severity, individual measures of fatigue, cognitive dysfunction, depression and anxiety, insomnia severity, subjective sleep quality, and sleep diary outcome measures. The beneficial effects of CBT-I on overall GWI symptom severity and most individual GWI symptom measures were maintained 6-months after treatment.SignificanceGWI symptoms have historically been difficult to treat. Because CBT-I, which is associated with low stigma and is increasingly readily available to veterans, improved both sleep and non-sleep symptoms of GWI, these results suggest that a comprehensive approach to the treatment of GWI should include behavioral sleep interventions.

Study objectivesInsomnia 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.MethodsParticipants 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.ResultsISI 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.ConclusionsFindings 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.

Study objectivesOur study aims were to examine (1) the association between fear of sleep and posttraumatic stress disorder (PTSD) symptoms, (2) the association between fear of sleep and subjective and objective insomnia symptoms and disruptive behaviors during sleep, and (3) whether fear of sleep decreases following cognitive behavioral therapy for insomnia (CBT-I).MethodsForty-five adults with PTSD and insomnia participated in the study. Fear of sleep was assessed using the Fear of Sleep Inventory; PTSD symptoms were assessed using the Clinician Administered PTSD Scale; and sleep disturbance symptoms were assessed using the Insomnia Severity Index, polysomnography, sleep diaries, and the Pittsburgh Sleep Quality Index Addendum for PTSD. Participants were randomly assigned to 8 weeks of CBT-I (n = 29) or a waitlist control condition (n = 16).ResultsGreater fear of sleep was associated with greater PTSD symptom severity, greater nightmare frequency, and greater hypervigilance intensity. Greater fear of sleep was associated with decreased wake after sleep onset (WASO), reduced total sleep time, and greater disruptive nocturnal behaviors. Following CBT-I, there was a significant reduction in fear of sleep compared to the waitlist condition. These improvements persisted 6 months later.ConclusionsFear of sleep was related to sleep disturbances specific to trauma rather than "classic" insomnia symptoms. Unexpectedly, greater fear of sleep was associated with reduced WASO. These results may be related to having a truncated sleep period and thus more consolidated sleep. Fear of sleep deceased following CBT-I despite not being a permissible target for this research protocol and not being related to insomnia symptoms.Clinical trial registrationRegistry: CinicalTrials.gov; Name: Treating People with Post-traumatic Stress Disorder with Cognitive Behavioral Therapy for Insomnia; Identifier: NCT00881647; URL: https://clinicaltrials.gov/ct2/show/NCT00881647.

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. 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.

Objective: Although behavioral treatments are recommended for treating insomnia disorder, these treatments are not the most commonly provided treatments due to numerous barriers (e.g., treatment length, time limitations). Brief Behavioral Treatment for Insomnia (BBTI) was developed, in part, to help overcome these barriers. The purpose of the current study was to qualitatively examine the treatment experiences of veterans with insomnia disorder participating in BBTI. Methods: All veterans (n=46) who were randomized to receive BBTI as part of a randomized clinical trial participated in 10-20 minute semi-structured interviews one week after completing treatment. Rapid analysis procedures were used for qualitative analysis. Results: Thirteen qualitative themes were identified: BBTI provided veterans with the skills they believed they needed to continue improving independently post-treatment; beginning BBTI with in-person sessions was valued; phone sessions helped participation; veterans did not perceive that they could cover the same content during phone and in-person sessionsl; materials could be more portable; BBTI created accountability; BBTI required discipline and willingness; BBTI facilitated buy-in; BBTI was aligned with military culture; loved ones could provide important support; BBTI could be improved with more personalization; BBTI challenged expectations of mental health; and BBTI improved awareness of health behaviors beyond sleep. Conclusions: BBTI was successful in overcoming barriers to behavioral insomnia treatment and interviews identified critical treatment aspects that should be maintained to preserve acceptability (e.g., in-person session first). Areas in which BBTI did not fully meet the needs of veterans and targets for improvement (e.g., ameliorating understanding and expectations of phone sessions) were also identified.

Posttraumatic stress disorder (PTSD) and insomnia are characterized by sleep disturbances and daytime functional impairments. Actigraphy metrics can quantify diurnal rhythms via interdaily stability, intradaily variability, relative amplitude, and sleep regularity. Here, we (a) compared diurnal rhythms in PTSD, insomnia, and healthy control samples using linear mixed modeling; (b) compared inter-individual variability of diurnal rhythms between groups using variance ratio tests; and (c) examined correlations between diurnal rhythms and sleep measures within the clinical samples. Participants (N = 98) wore wrist-activity monitors for one week and completed the Insomnia Severity Index and Pittsburgh Sleep Quality Index. Both clinical samples displayed significantly lower interdaily stability, relative amplitude, and sleep regularity compared with controls. Individuals with PTSD and insomnia did not differ on mean diurnal rhythm metrics. Both clinical samples showed more inter-individual variability in relative amplitude compared with controls, and the individuals with PTSD were distinguished from those with insomnia by greater inter-individual variability in interdaily stability and relative amplitude. Relative amplitude in the clinical samples was positively correlated with objective sleep efficiency and total sleep time. This is the first study to compare individuals with PTSD and insomnia on measures of diurnal rhythms, revealing those with PTSD and insomnia to have less robust and more variable diurnal rhythms compared with controls. Individuals with PTSD differed from those with insomnia in inter-individual variability of diurnal rest-activity stability and amplitude, highlighting this population as particularly heterogenous. Diurnal rhythm robustness might be considered an intervention target in insomnia and PTSD populations. [ABSTRACT FROM AUTHOR]

Sleep disturbances are prevalent in posttraumatic stress disorder (PTSD) and are associated with a number of adverse health consequences. Few studies have used comprehensive assessment methods to characterize sleep in Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn (OEF/OIF/OND) veterans with PTSD. OEF/OIF/OND veterans with PTSD and sleep disturbance ( n = 45) were compared to patients with primary insomnia ( n = 25) and healthy control subjects ( n = 27). Participants were assessed using questionnaire-based measures as well as daily subjective and objective measures of sleep. The 3 groups were compared with regard to (a) group means, (b) intraindividual (i.e., night-to-night) variability of sleep, and (c) interindividual (i.e., within-group) variability of sleep. In terms of group means, only objective sleep efficiency was significantly worse with PTSD than with primary insomnia ( d = 0.54). Those with PTSD differed from those with primary insomnia on measures of intraindividual as well as interindividual variability ( d = 0.48-0.73). These results suggested sleep symptoms in OEF/OIF/OND veterans with PTSD are more variable across nights and less consistent across patients relative to sleep symptoms in insomnia patients without PTSD. These findings have implications for research, as well as for personalizing treatment for individuals with PTSD. [ABSTRACT FROM AUTHOR]

To examine whether cognitive behavioral therapy for insomnia (CBT-I), delivered by telephone, improves sleep and non-sleep symptoms of Gulf War Illness (GWI). Eighty-five Gulf War veterans (21 women, mean age: 54 years, range 46–72 years) who met the Kansas GWI case definition, the Centers for Disease Control and Prevention (CDC) case definition for Chronic Multisymptom Illness (CMI), and research diagnostic criteria for insomnia disorder were randomly assigned to CBT-I or monitor-only wait list control. Eight weekly sessions of individual CBT-I were administered via telephone by Ph.D. level psychologists to study participants. Outcome measures included pre-, mid-, and post-treatment assessments of GWI and insomnia symptoms, subjective sleep quality, and continuous sleep monitoring with diary. Outcomes were re-assessed 6-months post-treatment in participants randomized to CBT-I. Compared to wait list, CBT-I produced significant improvements in overall GWI symptom severity, individual measures of fatigue, cognitive dysfunction, depression and anxiety, insomnia severity, subjective sleep quality, and sleep diary outcome measures. The beneficial effects of CBT-I on overall GWI symptom severity and most individual GWI symptom measures were maintained 6-months after treatment. GWI symptoms have historically been difficult to treat. Because CBT-I, which is associated with low stigma and is increasingly readily available to veterans, improved both sleep and non-sleep symptoms of GWI, these results suggest that a comprehensive approach to the treatment of GWI should include behavioral sleep interventions. • Insomnia and sleep disturbance are common symptoms of Gulf War Illness (GWI). • Cognitive Behavioral Therapy for Insomnia (CBT-I) is efficacious for insomnia. • CBT-I produced durable improvements in both sleep and non-sleep symptoms of GWI. • CBT-I has great potential for managing and reducing Gulf War Illness symptoms.
