The impact of prolonged exposure on sleep and enhancing treatment outcomes with evidence-based sleep interventions: A pilot study.

OBJECTIVE: Insomnia and nightmares are central features of posttraumatic stress disorder (PTSD). However, often they are inadequately assessed and ineffectively resolved following gold-standard PTSD treatment. Here we: (a) evaluate effects of prolonged exposure (PE) on subjectively measured sleep and (b) present pilot results of an examination of whether adding sleep interventions (imagery rehearsal therapy [IRT] and cognitive-behavioral therapy for insomnia [CBT-I]) to PE improves treatment response, relative to PE alone, for night- and/or daytime PTSD symptoms among returning U.S. veterans and postdeployment personnel. METHOD: In a parallel-groups, randomized controlled trial, participants received 12 sessions of PE followed by IRT (5 weeks) and CBT-I (7 weeks) or PE followed by 12 weeks supportive care therapy (SCT). RESULTS: PE did not improve sleep to a clinically meaningful degree, despite significant improvements in both Clinical Administered PTSD Scale and PTSD Checklist. Enhancing treatment with IRT/CBT-I led to greater improvements in insomnia (diary-recorded sleep efficiency) symptoms with large effect size, relative to SCT (p = .068, d = 1.07). There were large improvements in nightmare frequency relative SCT that did not reach statistical significance (p = .11, d = 0.90). Moreover, there was small improvement in daytime symptoms (Clinical Administered PTSD Scale) that did not reach statistical significance (p = .54, d = .31). CONCLUSION: The addition of targeted, validated sleep treatment improves effects of PE and improves nighttime symptoms. Thus, evidence-based sleep treatment should be considered in comprehensive PTSD treatment. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Spirituality and Mental Well-Being in Combat Veterans: A Systematic Review.

BACKGROUND: Many veterans experience significant compromised spiritual and mental well-being. Despite effective and evidence-based treatments, veterans continue to experience poor completion rates and suboptimal therapeutic effects. Spirituality, whether expressed through religious or secular means, is a part of adjunctive or supplemental treatment modalities to treat post-traumatic stress disorder (PTSD) and is particularly relevant to combat trauma. The aim of this systematic review was to examine the relationship between spirituality and mental well-being in postdeployment veterans. METHODS: Electronic databases (MEDLINE, PsycINFO, CINAHL, Web of Science, JSTOR) were searched from database inception to March 2016. Gray literature was identified in databases, websites, and reference lists of included studies. Study quality was assessed using the Effective Public Health Practice Project Quality Assessment Tool and Critical Appraising Skill Programme Qualitative Checklist. RESULTS: From 6,555 abstracts, 43 studies were included. Study quality was low-moderate. Spirituality had an effect on PTSD, suicide, depression, anger and aggression, anxiety, quality of life, and other mental well-being outcomes for veterans. "Negative spiritual coping" was often associated with an increase mental health diagnoses and symptom severity; "positive spiritual coping" had an ameliorating effect. DISCUSSION: Addressing veterans' spiritual well-being should be a routine and integrated component of veterans' health, with regular assessment and treatment. This requires an interdisciplinary approach, including integrating chaplains postcombat, to help address these issues and enhance the continuity of care. Further high-quality research is needed to isolate the salient components of spirituality that are most harmful and helpful in veterans' mental well-being, including the incorporating of veterans' perspectives directly.

Deployment-related insomnia in military personnel and veterans.

Insomnia is a prevalent disorder that greatly impacts military personnel, especially those deployed in support of combat efforts. Deployment-related stressors like combat exposure, mild traumatic brain injury (mTBI) irregular sleep-wake schedules, and adjustment to the return home all contribute to insomnia. However, insomnia can also exacerbate the deployment experience and is a risk factor for traumatic stress reactions such as PTSD, depression, and suicide. Military personnel with mTBI are significantly impacted by insomnia; the majority experience sleep disruption and this can impede recovery and rehabilitation. As more service members return home from deployment, treatment is vital to reduce the impact of insomnia. Preliminary outcome data, showing positive results for reduction of sleep disruption, has been found with treatments such as combined cognitive behavioral treatment of insomnia (CBTI) and imagery rehearsal therapy (IRT), preference-based interventions, as well as efforts to broadly disseminate CBTI. The recent literature on the impact and treatment of deployment-related insomnia is reviewed.

Combat-related PTSD nightmares and imagery rehearsal: nightmare characteristics and relation to treatment outcome.

The characteristics of nightmares of 48 male U.S. Vietnam war veterans with combat-related posttraumatic stress disorder (PTSD), as well as revised dream scripts developed in the course of Imagery Rehearsal therapy, were examined in relation to pretreatment symptomatology and treatment outcome. Features, content, and themes of nightmares and rescripted dreams were coded by 2 independent raters. Nightmares were replete with scenes of death and violence and were predominantly replays of actual combat events in which the veteran was under attack and feared for his life. Although addressing or resolving the nightmare theme with rescripting was associated with a reduction in sleep disturbance, references to violence in the rescripted dream were related to poorer treatment outcome in nightmare frequency; B  = 5.69 (SE = 1.14). The experience of olfactory sensations in nightmares, a possible index of nightmare intensity, was also related to poorer treatment response; B  = 2.95 (SE = 1.06). Imagery rehearsal for individuals with severe, chronic PTSD and fairly replicative nightmares may be most effective when the rescripted dream incorporates a resolution of the nightmare theme and excludes violent details.

K-complexes are not preferentially evoked to combat sounds in combat-exposed Vietnam veterans with and without post-traumatic stress disorder.

The primary objective was to compare the evoked K-complex response to salient versus non-salient auditory stimuli in combat-exposed Vietnam veterans with and without post-traumatic stress disorder (PTSD). Three categories of auditory stimuli (standard 1000Hz tones, trauma-related combat sounds, and affectively neutral environmental sounds) were presented during stage 2 sleep utilizing an oddball paradigm with probabilities of occurrence of 60%, 20% and 20% respectively. Twenty-four combat-exposed Vietnam veterans, 14 with PTSD and 10 without PTSD were studied in a sleep laboratory at the National Center for PTSD in Menlo Park, CA. While significantly fewer K-complexes overall were elicited in patients, there were no differences in the proportion of K-complexes elicited by tones and combat stimuli within either group. Patients produced significantly more K-complexes to neutral stimuli than to tone or combat stimuli. Examination of the N550 component of the evoked K-complex revealed significantly longer latencies in the patient group. Across the entire sample, N550 latencies were longer for combat stimuli relative to tone neutral stimuli. There were no group or stimulus category differences for N550 amplitude. The results suggest that salient information, as defined by trauma-related combat sounds, did not preferentially elicit K-complexes in either the PTSD group or the control group, suggesting that K-complexes function to protect sleep more than to endogenously process meaningful stimuli.

He's home, but he's not the same: a pastoral counseling impression of family care after combat related traumatic brain injury.

As the occurrence of direct contact with heavy improvised explosive devices has increased in Operation Enduring Freedom, more and more veterans are returning home from combat deployment with traumatic brain injuries (TBI). Although these injuries are associated with many different neurological, physiological, and emotional symptoms, perhaps most difficult for families is the phenomenon of perceived personality change. This article examines common clinical interventions in treating personality change associated with TBI, and offers pastoral context and insights for complementary care with families during the return and reunion process.

Subjective age, PTSD and physical health among war veterans.

OBJECTIVES: To examine the contribution of posttraumatic stress disorder (PTSD) and physical health to subjective age among war veterans. METHOD: The sample included 502 veterans of the first Lebanon War who were assessed 20 years after the war by a series of self-report questionnaires. Data analyses included descriptive statistics, hierarchical and logistic regressions. RESULTS: Veterans with PTSD reported older subjective age than veterans without PTSD. Furthermore, both PTSD and general physical health contributed to subjective age, above and beyond chronological age and negative life events. Among the physical health problems, memory problems and weight gain were found to contribute to older age identity. In addition, the relation between general physical health and subjective age was stronger among veterans without PTSD than among veterans with PTSD. DISCUSSION: Possible explanations, clinical implications for integrative therapy for elderly PTSD victims, and recommendations for future research are presented.
