Mechanisms of change in posttraumatic headache-related disability: A mediation model.

OBJECTIVE: To explore whether the association between change in headache management self-efficacy and posttraumatic headache-related disability is partially mediated by a change in anxiety symptom severity. BACKGROUND: Many cognitive-behavioral therapy treatments for headache emphasize stress management, which includes anxiety management strategies; however, little is currently known about mechanisms of change in posttraumatic headache-related disability. Increasing our understanding of mechanisms could lead to improvements in treatments for these debilitating headaches. METHODS: This study is a secondary analysis of veterans (N = 193) recruited to participate in a randomized clinical trial of cognitive-behavioral therapy, cognitive processing therapy, or treatment as usual for persistent posttraumatic headache. The direct relationship between headache management self-efficacy and headache-related disability, along with partial mediation through change in anxiety symptoms was tested. RESULTS: The mediated latent change direct, mediated, and total pathways were statistically significant. The path analysis supported a significant direct pathway between headache management self-efficacy and headache-related disability (b = -0.45, p < 0.001; 95% confidence interval [CI: -0.58, -0.33]). The total effect of change of headache management self-efficacy scores on change in Headache Impact Test-6 scores was significant with a moderate-to-strong effect (b = -0.57, p = 0.001; 95% CI [-0.73, -0.41]). There was also an indirect effect through anxiety symptom severity change (b = -0.12, p = 0.003; 95% CI [-0.20, -0.04]). CONCLUSIONS: In this study, most of the improvements in headache-related disability were related to increased headache management self-efficacy with mediation occurring through change in anxiety. This indicates that headache management self-efficacy is a likely mechanism of change of posttraumatic headache-related disability with decreases in anxiety explaining part of the improvement in headache-related disability.

The interactions between patient preferences, expectancies, and stigma contribute to posttraumatic stress disorder treatment outcomes.

Cognitive processing therapy (CPT) is an effective treatment for posttraumatic stress disorder (PTSD); however, some patients do not improve to the same extent as others. It is important to understand potential factors that can be modified for better patient outcomes. This clinical trial implemented a three-arm, equipoise-stratified randomization design to allow for the accommodation of patient preference before randomization to one of three CPT treatment modalities: in-home, in-office, or telehealth. This study examined whether satisfaction with the modality, perceived stigma, expectations of therapy, and credibility of the therapist differed between modalities and whether these factors impacted treatment outcomes. We hypothesized that the contributions of these variables would depend upon whether participants opted out of any treatment arms and that these factors would predict treatment outcomes. Participants who endorsed less perceived stigma demonstrated larger reductions in PTSD symptom severity than those with similar levels of perceived stigma in the telehealth and in-office conditions, η2 = .12-.18. Participants who endorsed lower satisfaction with their treatment modality and were assigned to the in-home condition experienced larger PTSD symptom reductions than those with similar dissatisfaction in the telehealth and in-office conditions, η2 = .20. The results show the robustness of evidence-based therapies for PTSD given that dissatisfaction did not impede treatment success. In addition, they demonstrate that it is important for clinicians to address stigma before initiating evidence-based therapies for PTSD. Strategies to address these factors are discussed.

Treatment of comorbid sleep disorders and posttraumatic stress disorder in U.S. active duty military personnel: A pilot randomized clinical trial.

Insomnia and nightmares are common in patients with posttraumatic stress disorder (PTSD). They are associated with worse psychological and physical health and worse PTSD treatment outcomes. In addition, they are resistant to PTSD treatments, which do not typically address sleep disorders. Cognitive behavioral therapy for insomnia and nightmares (CBT-I&N) and cognitive processing therapy (CPT) for PTSD are first-line treatments, but limited evidence exists guiding the treatment of individuals with all three disorders. The current study randomized U.S. military personnel (N = 93) to one of three conditions: CBT-I&N delivered before CPT, CBT-I&N delivered after CPT, or CPT alone; all groups received 18 sessions. Across groups, participants demonstrated significantly improved PTSD symptoms. Because the study was terminated prematurely due to challenges with recruitment and retention, it was underpowered to answer the initially intended research questions. Nonetheless, statistical findings and relevant clinically meaningful changes were observed. Compared to participants who received CPT alone, those who received CBT-I&N and CPT, regardless of sequencing, demonstrated larger improvements in PTSD symptoms, d = -0.36; insomnia, d = -0.77; sleep efficiency, d = 0.62; and nightmares, d = -.53. Compared to participants who received CBT-I&N delivered before CPT, those who received CBT-I&N delivered after CPT demonstrated larger improvements in PTSD symptoms, d = 0.48, and sleep efficiency, d = -0.44. This pilot study suggests that treating comorbid insomnia, nightmares, and PTSD symptoms results in clinically meaningful advantages in improvement for all three concerns compared to treating PTSD alone.

In-office, in-home, and telehealth cognitive processing therapy for posttraumatic stress disorder in veterans: a randomized clinical trial.

BACKGROUND: Trauma-focused psychotherapies for combat-related posttraumatic stress disorder (PTSD) in military veterans are efficacious, but there are many barriers to receiving treatment. The objective of this study was to determine if cognitive processing therapy (CPT) for PTSD among active duty military personnel and veterans would result in increased acceptability, fewer dropouts, and better outcomes when delivered In-Home or by Telehealth as compared to In-Office treatment. METHODS: The trial used an equipoise-stratified randomization design in which participants (N = 120) could decline none or any 1 arm of the study and were then randomized equally to 1 of the remaining arms. Therapists delivered CPT in 12 sessions lasting 60-min each. Self-reported PTSD symptoms on the PTSD Checklist for DSM-5 (PCL-5) served as the primary outcome. RESULTS: Over half of the participants (57%) declined 1 treatment arm. Telehealth was the most acceptable and least often refused delivery format (17%), followed by In-Office (29%), and In-Home (54%); these differences were significant (p = 0.0008). Significant reductions in PTSD symptoms occurred with all treatment formats (p < .0001). Improvement on the PCL-5 was about twice as large in the In-Home (d = 2.1) and Telehealth (d = 2.0) formats than In-Office (d = 1.3); those differences were statistically large and significant (d = 0.8, 0.7 and p = 0.009, 0.014, respectively). There were no significant differences between In-Home and Telehealth outcomes (p = 0.77, d = -.08). Dropout from treatment was numerically lowest when therapy was delivered In-Home (25%) compared to Telehealth (34%) and In-Office (43%), but these differences were not statistically significant. CONCLUSIONS: CPT delivered by telehealth is an efficient and effective treatment modality for PTSD, especially considering in-person restrictions resulting from COVID-19.

Secondary individual outcomes following multicouple group therapy for posttraumatic stress disorder: An uncontrolled pilot study with military dyads.

Cognitive-behavioral conjoint therapy (CBCT) for posttraumatic stress disorder (PTSD) has demonstrated efficacy for improving PTSD and comorbid symptoms and relationship adjustment. To enhance treatment efficiency and scalability, we developed a 2-day, abbreviated, intensive, multicouple group version of CBCT for PTSD (AIM-CBCT for PTSD). Prior work demonstrated that AIM-CBCT for PTSD wasassociated with reductions in PTSD and comorbid symptoms in a sample of 24 post-9/11 active duty military or veteran couples who received the treatment in a retreat format over a single weekend. The current study investigated secondary outcomes regarding trauma-related cognitions, psychosocial impairment, and insomnia. For trauma-related cognitions, reductions were nonsignificant and small at 1-month follow-up, ds = -0.14 to -0.32. However, by 3-month follow-up, there were significant, medium effect size reductions in total trauma-related cognitions, d = -0.68, and negative views of self and others, ds = -0.64 and -0.57, respectively, relative to baseline. There was also a nonsignificant, small-to-medium effect-size reduction in self-blame, d = -0.43, p = .053, by 3-month follow-up. For psychosocial impairment, there were significant and medium-to-large and large effect size reductions by 1- and 3-month follow-ups, ds = -0.73 and -0.81, respectively. There were nonsignificant, small effect size reductions in insomnia at both 1- and 3-month follow-ups relative to baseline, ds = -0.30 and -0.34, respectively. These findings suggest that AIM-CBCT for PTSD is associated with reductions in maladaptive posttraumatic cognitions and psychosocial impairment but that adjunctive interventions may be needed to address insomnia.

The impact of prior head injury on outcomes following group and individual cognitive processing therapy among military personnel.

This study examined the impact of a history of head injury (HHI) on posttraumatic stress disorder (PTSD) and depression symptoms in active duty military personnel following group and individual cognitive processing therapy (CPT). Data for these secondary analyses were drawn from a clinical trial comparing group and individual CPT. Service members (N = 268, 91.0% male) were randomized to 12 sessions of group (n = 133) or individual (n = 135) CPT. Most participants (57.1%) endorsed a deployment-related HHI, 92.8% of whom reported currently experiencing symptoms (CES) related to the head injury (i.e., HHI/CES). Patients classified as non-HHI/CES demonstrated large, significant improvements in PTSD symptom severity in both individual and group therapy, ds = 1.1, p < .001. Patients with HHI/CES status showed similar significant improvements when randomized to individual CPT, d = 1.4, p < .001, but did not demonstrate significant improvements when randomized to group CPT, d = 0.4, p = .060. For participants classified as HHI/CES, individual CPT was significantly superior to group CPT, d = 0.98, p = .003. Symptoms of depression improved following treatment, with no significant differences by treatment delivery format or HHI/CES status. The findings of this clinical trial subgroup study demonstrate evidence that group CPT is less effective than individual CPT for service members classified as HHI/CES. The results suggest that HHI/CES status may be important to consider in selecting patients for group or individual CPT; additional research is needed to confirm the clinical implications of these findings.

Testing the role of aerobic exercise in the treatment of posttraumatic stress disorder (PTSD) symptoms in U.S. active duty military personnel: a pilot study.

The purpose of this pilot study was to determine if the efficacy of imaginal exposure for symptoms of posttraumatic stress disorder (PTSD) could be improved by adding aerobic exercise. We hypothesized that aerobic exercise would enhance the efficacy of exposure therapy. Active duty service members with clinically significant symptoms of posttraumatic stress (PTSD Checklist-Stressor-Specific Version, [PCL-S], ≥25) were randomized into one of four conditions: exercise only; imaginal exposure only; imaginal exposure plus exercise; no exercise/no exposure therapy (control). Participants (N = 72) were primarily male, Army, noncommissioned officers ranging in age from 22 to 52. PTSD symptom severity decreased over time (p < .0001); however, there were no significant differences between the experimental conditions. The prediction that imaginal exposure augmented with aerobic exercise would be superior to either imaginal exposure alone or aerobic exercise alone was not supported, suggesting that engaging in exercise and imaginal exposure simultaneously may not be any better than engaging in either activity alone. A better understanding of individually administered and combined exercise and exposure therapy interventions for PTSD is warranted.

Persistent posttraumatic headaches and functioning in veterans: Injury type can matter.

OBJECTIVE: To characterize the relationship between head trauma types (blast injury, blunt injury, combined blast+blunt injury) with subsequent headache presentations and functioning. BACKGROUND: Posttraumatic headaches (PTHs), the most common sequelae of traumatic brain injury (TBI), are painful and disabling. More than 400,000 veterans report having experienced a TBI, and understanding the predictors of PTHs may guide treatment developments. METHODS: This study used a nested-cohort design analyzing baseline data from a randomized clinical trial of cognitive behavioral therapy for PTH (N = 190). Participants had PTH (from blast and/or blunt head trauma) and symptoms of posttraumatic stress disorder (PTSD). The Structured Diagnostic Interview for Headache-Revised and Ohio State University Traumatic Brain Injury Identification Method were used to phenotype headaches and head injury histories, respectively. RESULTS: Individuals with persistent PTHs after a combined blast and blunt head trauma were more likely (OR =3.45; 95% CI [1.41, 8.4]) to experience chronic (vs. episodic) PTHs compared with the blunt trauma only group (23/33, 70% vs. 26/65, 40%, respectively); and they were more likely (OR =2.51; 95% CI [1.07, 5.9]) to experience chronic PTH compared with the blast trauma only group (44/92, 48%). There were no differences between head injury type on headache-related disability, depression symptoms, or severity of PTSD symptoms. CONCLUSION: The combination of blast and blunt injuries was associated with headache chronicity, but not headache disability. Considering the refractory nature of chronic headaches, the potential added and synergistic effects of distinct head injuries warrant further study.

Prazosin for treatment of post-traumatic stress disorder: a systematic review and meta-analysis.

BACKGROUND: Prazosin has been an accepted treatment for patients with post-traumatic stress disorder (PTSD) who experience sleep disturbances, including nightmares. Results of a recent large randomized control trial did not find benefit of prazosin vs placebo in improving such outcomes. A meta-analysis that includes this most recent trial was conducted to examine the pooled effect of prazosin vs placebo on sleep disturbances and overall PTSD symptoms in patients with PTSD. METHODS: A systematic review of the published literature on trials comparing prazosin vs placebo for improvement of overall PTSD scores, nightmares, and sleep quality was conducted. Hedges' g standardized mean differences (SMD) between prazosin and placebo were calculated for each outcome across studies. RESULTS: Six randomized placebo-controlled studies representing 429 patients were included in the analysis, including two studies with a crossover design. Results showed prazosin significantly improved overall PTSD scores (SMD = -0.31; 95% confidence intervals [CI]: -0.62, -0.01), nightmares (SMD = -0.75; 95% CI: -1.24, -0.27), and sleep quality (SMD = -0.57; 95% CI: -1.02, -0.13). In the largest trial, prazosin showed a reduction in clinical outcome measures similar to past studies, but a relatively large placebo effect size, particularly for nightmares, contributed to no treatment differences. CONCLUSIONS: Despite the results of a recent, large randomized study, pooled effect estimates show that prazosin has a statistically significant benefit on PTSD symptoms and sleep disturbances. Limitations that should be considered include heterogeneity of study design and study populations as well as the small number of studies conducted and included in this meta-analysis.

The Impact of Hazardous Drinking Among Active Duty Military With Posttraumatic Stress Disorder: Does Cognitive Processing Therapy Format Matter?

This study was a secondary data analysis of clinical trial data collected from 268 active duty U.S. military service members seeking cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) at Fort Hood, Texas, related to combat operations following September 11, 2001. Our primary aim was to evaluate changes in PTSD symptom severity and alcohol misuse as a function of baseline hazardous drinking and treatment format (i.e., group or individual). At baseline and posttreatment, PTSD was assessed using the PTSD Symptom Scale-Interview Version and PTSD Checklist for DSM-5. Hazardous drinking was categorically defined as an Alcohol Use Disorder Identification Test total score of 8 or higher. Employing intent-to-treat, mixed-effects regression analysis, all groups reported reduced PTSD symptom severity, Hedges' gs = -0.33 to -1.01, except, unexpectedly, nonhazardous drinkers who were randomized to group CPT, Hedges' g = -0.12. Hazardous drinkers who were randomized to individual therapy had larger reductions in PTSD symptoms than nonhazardous drinkers who were randomized to group CPT, Hedges' g = -0.25. Hazardous drinkers also reported significant reductions in alcohol misuse, regardless of treatment format, Hedges' gs = -0.78 to -0.86. This study builds upon an emerging literature suggesting that individuals with PTSD and co-occurring alcohol use disorder can engage successfully in CPT, which appears to be an appropriate treatment for these individuals whether it is delivered individually or in a group format. However, as a portion of participants remained classified as hazardous drinkers at posttreatment, some individuals may benefit from integrated treatment.

A Closer Examination of Relational Outcomes from a Pilot Study of Abbreviated, Intensive, Multi-Couple Group Cognitive-Behavioral Conjoint Therapy for PTSD with Military Dyads.

Cognitive-behavioral conjoint therapy for posttraumatic stress disorder (CBCT for PTSD) is associated with improvements in patients' PTSD symptoms, partners' psychological distress, and relationship satisfaction. However, little is known about whether CBCT for PTSD is associated with changes in other relationship domains that have theoretical and clinical relevance to the relational context of PTSD. The current study is a secondary analysis of relational outcomes from an uncontrolled, within-group trial designed to examine whether an abbreviated, intensive, multi-couple group version of CBCT for PTSD (AIM-CBCT for PTSD) delivered in a retreat during a single weekend was associated with improvements in PTSD symptoms and relationship satisfaction. In this investigation, we examined whether AIM-CBCT for PTSD is also associated with improvements in ineffective arguing, supportive dyadic coping by partner, joint dyadic coping, and partners' accommodation of patients' PTSD symptoms. Participants were 24 couples who included a post-9/11 U.S. service member or veteran with PTSD. At 1- and 3-month follow-up, patients reported significant reductions in couples' ineffective arguing (ds = -.71 and -.78, respectively) and increases in supportive dyadic coping by partners relative to baseline (ds = .50 and .44, respectively). By 3-month follow-up, patients also reported significant increases in couples' joint dyadic coping (d = .57), and partners reported significant reductions in their accommodation of patients' PTSD symptoms (d = -.44). Findings suggest that AIM-CBCT for PTSD is associated with improvements in multiple relationship domains beyond relationship satisfaction but that these may be differentially salient for patients and partners.

La terapia cognitivo-conductual conjunta para el trastorno por estrés postraumático (TCC para el TEPT) está asociada con mejoras en los síntomas de TEPT de los pacientes, en el distrés psicológico de sus parejas y en la satisfacción con la relación. Sin embargo, se sabe poco acerca de si la TCC para el TEPT está asociada con cambios en otros aspectos de la relación que son de interés teórico y clínico para el contexto relacional del TEPT. El presente estudio es un análisis secundario de los resultados relacionales de un ensayo intragrupal no controlado diseñado para analizar si una versión grupal multipareja, intensiva y abreviada de la TCC para el TEPT (MIA-TCC para el TEPT) practicada en un retiro durante un solo fin de semana estuvo asociada con mejoras en los síntomas de TEPT y en la satisfacción con la relación. En esta investigación, analizamos si la MIA-TCC para el TEPT también está asociada con mejoras en las discusiones ineficaces, en el afrontamiento diádico comprensivo de la pareja del paciente, en el afrontamiento diádico conjunto y en la adaptación de las parejas de los pacientes a sus síntomas de TEPT. Los participantes fueron 24 parejas en las que había un miembro o veterano de las Fuerzas Armadas de los Estados Unidos que prestó servicio con posterioridad al 11/9 y que tenía TEPT. En el seguimiento del mes y de los tres meses, los pacientes informaron reducciones significativas de las discusiones ineficaces de la pareja (ds = -0.71 y -0.78, respectivamente) y aumentos del afrontamiento diádico comprensivo de sus parejas en relación con el momento basal (ds = 0.50 y 0.44, respectivamente). En el seguimiento de los tres meses, los pacientes también informaron aumentos significativos del afrontamiento diádico conjunto de las parejas (d = 0.57), y sus parejas informaron reducciones significativas de su adaptación a los síntomas de TEPT de los pacientes (d = -0.44). Los resultados sugieren que la MIA-TCC para el TEPT está asociada con mejoras en varios aspectos de las relaciones aparte del de la satisfacción en la pareja, pero que estos pueden tener una importancia diferente para los pacientes y sus parejas.

Post-9/11 service members: Associations between gender, marital status, and psychiatric aeromedical evacuations from combat zones.

Psychiatric aeromedical evacuations are one of the leading causes of medical related evacuations of US military personnel from combat. Currently, no studies have examined gender and marital status of individuals who were evacuated from combat for a psychiatric diagnosis. Psychiatric aeromedical evacuation data from 5,957 United States military personnel deployed to Iraq or Afghanistan between 2001 and 2013 were analyzed using chi-square tests of independence, odds ratios (OR), and standardized residuals. Analyses showed that female service members were evacuated at higher rates (178 per 100,000) than males (115 per 100,000). When compared to nonmarried females, married females did not present with increased risk of psychiatric aeromedical evacuation on any diagnosis. Married males, however, were more likely to be evacuated than married females for PTSD (OR = 1.98) and TBI (OR = 1.14). Likewise, married males, compared to nonmarried males, were more likely to be evacuated for PTSD (OR = 1.66) and anxiety (OR = 1.38). Although deployments can be extremely stressful experiences for some military service members, they may be especially so among unmarried females and married males. This study provides a unique contribution to enhancing the understanding of risk factors related to psychiatric aeromedical evacuation for deployed service members.

Manage Emotions to Reduce Aggression: A Pilot Study of a Brief Treatment to Help Veterans Reduce Impulsive Aggression.

Veterans with posttraumatic stress disorder (PTSD) report more aggression than civilians with PTSD. Because emotion regulation difficulties mediated the relationship between PTSD symptoms and impulsive aggression in veterans, we developed an intervention to increase emotion regulation skills. This pilot study tested the feasibility and acceptability of a three-session treatment, Manage Emotions to Reduce Aggression (MERA), and examined its effectiveness at reducing aggression and emotion dysregulation. Male combat veterans with PTSD and impulsive aggression completed assessments before and 4 weeks after MERA. Overt Aggression Scale measured frequency of aggression; Difficulties in Emotion Regulation Scale assessed emotion dysregulation. Most veterans (95%) who completed MERA and the posttreatment assessment (n = 20) reported MERA was helpful. Veterans in the intent-to-treat sample demonstrated a significant decrease in their frequency of aggression (Cohen's d = -0.55) and emotion dysregulation (Cohen's d = -0.55). MERA may be an innovative treatment that helps veterans reduce aggression.

Changes in anger and aggression after treatment for PTSD in active duty military.

OBJECTIVE: To examine whether treating posttraumatic stress disorder (PTSD) reduces anger and aggression and if changes in PTSD symptoms are associated with changes in anger and aggression. METHOD: Active duty service members (n = 374) seeking PTSD treatment in two randomized clinical trials completed a pretreatment assessment, 12 treatment sessions, and a posttreatment assessment. Outcomes included the Revised Conflict Tactics Scale and state anger subscale of the State-Trait Anger Expression Inventory. RESULTS: Treatment groups were analyzed together. There were small to moderate pretreatment to posttreatment reductions in anger (standardized mean difference [SMD] = -0.25), psychological aggression (SMD = -0.43), and physical aggression (SMD = -0.25). The majority of participants continued to endorse anger and aggression at posttreatment. Changes in PTSD symptoms were mildly to moderately associated with changes in anger and aggression. CONCLUSIONS: PTSD treatments reduced anger and aggression with effects similar to anger and aggression treatments; innovative psychotherapies are needed.

The pattern of symptom change during prolonged exposure therapy and present-centered therapy for PTSD in active duty military personnel.

BACKGROUND: Few studies have investigated the patterns of posttraumatic stress disorder (PTSD) symptom change in prolonged exposure (PE) therapy. In this study, we aimed to understand the patterns of PTSD symptom change in both PE and present-centered therapy (PCT). METHODS: Participants were active duty military personnel (N = 326, 89.3% male, 61.2% white, 32.5 years old) randomized to spaced-PE (S-PE; 10 sessions over 8 weeks), PCT (10 sessions over 8 weeks), or massed-PE (M-PE; 10 sessions over 2 weeks). Using latent profile analysis, we determined the optimal number of PTSD symptom change classes over time and analyzed whether baseline and follow-up variables were associated with class membership. RESULTS: Five classes, namely rapid responder (7-17%), steep linear responder (14-22%), gradual responder (30-34%), non-responder (27-33%), and symptom exacerbation (7-13%) classes, characterized each treatment. No baseline clinical characteristics predicted class membership for S-PE and M-PE; in PCT, more negative baseline trauma cognitions predicted membership in the non-responder v. gradual responder class. Class membership was robustly associated with PTSD, trauma cognitions, and depression up to 6 months after treatment for both S-PE and M-PE but not for PCT. CONCLUSIONS: Distinct profiles of treatment response emerged that were similar across interventions. By and large, no baseline variables predicted responder class. Responder status was a strong predictor of future symptom severity for PE, whereas response to PCT was not as strongly associated with future symptoms.

Depression Suppresses Treatment Response for Traumatic Loss-Related Posttraumatic Stress Disorder in Active Duty Military Personnel.

There are multiple well-established evidence-based treatments for posttraumatic stress disorder (PTSD). However, recent clinical trials have shown that combat-related PTSD in military populations is less responsive to evidence-based treatments than PTSD in most civilian populations. Traumatic death of a close friend or colleague is a common deployment-related experience for active duty military personnel. When compared with research on trauma and PTSD in general, research on traumatic loss suggests that it is related to higher prevalence and severity of PTSD symptoms. Experiencing a traumatic loss is also related to the development of prolonged grief disorder, which is highly comorbid with depression. This study examined the association between having traumatic loss-related PTSD and treatment response to cognitive processing therapy in active duty military personnel. Participants included 213 active duty service members recruited across two randomized clinical trials. Results showed that service members with primary traumatic loss-related PTSD (n = 44) recovered less from depressive symptoms than those who reported different primary traumatic events (n = 169), B = -4.40. Tests of mediation found that less depression recovery suppressed recovery from PTSD symptoms in individuals with traumatic loss-related PTSD, B = 3.75. These findings suggest that evidence-based treatments for PTSD should better accommodate loss and grief in military populations.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) La depresión suprime la respuesta a tratamiento para el TEPT relacionado a una pérdida traumática en el personal militar en servicio activo PÉRDIDA TRAUMÁTICA Y TEPT EN MILITARES EN SERVICIO ACTIVO Hay múltiples tratamientos bien establecidos, basados en evidencia, para el trastorno de estrés postraumático (TEPT). Sin embargo, estudios clínicos recientes han mostrado que el TEPT relacionado a combate en poblaciones militares tiene menor respuesta a los tratamientos basados en la evidencia que el TEPT en la mayoría de las poblaciones civiles. La muerte traumática de un amigo o colega cercano es una experiencia común relacionada al despliegue para el personal militar en servicio activo. Cuando es comparada con la investigación en trauma y TEPT en general, la investigación en pérdida traumática sugiere que está relacionada a una mayor prevalencia y severidad de síntomas de TEPT. El experimentar una pérdida traumática se relaciona también al desarrollo de un trastorno de duelo prolongado, el cual tiene una alta comorbilidad con depresión. Este estudio examinó la asociación entre el tener TEPT relacionado a una pérdida traumática y la respuesta a tratamiento en la terapia de procesamiento cognitivo en personal militar en servicio activo. Los participantes incluyeron 213 miembros en servicio activo reclutados entre dos ensayos clínicos aleatorizados. Los resultados mostraron que los miembros con TEPT relacionado a pérdida traumática primaria (n = 44), se recuperaron menos de síntomas depresivos que aquellos que reportaron eventos traumáticos primarios diferentes (n = 169), B = -4.40. Las pruebas de mediación encontraron que una menor recuperación de la depresión suprimía la recuperación de los síntomas de TEPT en individuos con TEPT relacionado a pérdida traumática, B = 3.75. Estos hallazgos sugieren que los tratamientos basados en evidencia para el TEPT deberían acoger mejor la pérdida y el duelo en poblaciones militares.

Guilt in the Treatment of Posttraumatic Stress Disorder Among Active Duty Military Personnel.

The current study examined the role of trauma-related guilt on posttraumatic stress disorder (PTSD) symptom change during prolonged exposure therapy (PE) as well as the efficacy of PE in reducing three dimensions of guilt (responsibility, wrongdoing, and lack of justification) during treatment. Participants were 331 active duty U.S. military personnel seeking treatment for PTSD who were randomized to one of four groups: massed PE (10 sessions delivered over 2 weeks), spaced PE (10 sessions delivered over 8 weeks), present-centered therapy (PCT; 10 sessions delivered over 8 weeks), or minimal contact control (MCC; weekly therapist phone check-in for 4 weeks). The results showed that baseline guilt did not predict reductions in PTSD symptoms for spaced PE or for PCT, ps = .178-.387, ds = -0.02-0.07. Treatment condition (massed PE vs. MCC; spaced PE vs. PCT) did not moderate reductions in guilt for spaced PE versus PCT. Guilt decreased significantly over treatment in all groups, p < .001 to p = .038, ds = -0.19 to -0.42, except concerning justification in the spaced PE and PCT groups, p = .140, d = -0.10. The findings suggest that guilt may be reduced significantly following active PTSD treatment and attention control and that PTSD recovery is not impacted by baseline levels of trauma-related guilt in military personnel with PTSD, although reported levels of guilt were low to moderate in this sample.

Examination of Treatment Effects on Hazardous Drinking Among Service Members With Posttraumatic Stress Disorder.

Posttraumatic stress disorder (PTSD) and alcohol use disorder are frequently comorbid and present significant treatment challenges. Unfortunately, since the September 11, 2001, terrorist attacks in the United States, the rates of PTSD and hazardous drinking among active duty service members have increased significantly. Previous research on PTSD has typically excluded participants with current substance abuse. However, there is some research examining independent treatments for PTSD and substance abuse provided consecutively, concurrently, or as enhancements to other treatment. The current study examined the association between current hazardous drinking and PTSD treatment among 108 active duty service members with PTSD in a randomized controlled trial of group cognitive processing therapy and group present-centered therapy. Total scores above 8 on the Alcohol Use Disorders Identification Test defined hazardous alcohol use. At baseline, 25.0% of the sample was categorized as hazardous drinkers, and the hazardous and nonhazardous drinking groups did not differ in PTSD symptom severity, F(1, 106) = 0.08, p = .777, d = 0.06. Over the course of treatment, the two groups also did not differ significantly in PTSD symptom severity change on the PTSD Checklist, F(1, 106) = 1.20, p = .280, d = 0.33. Treatment for PTSD did not exacerbate hazardous drinking, and the hazardous drinking group showed significant reductions in drinking following PTSD treatment. Limitations and implications for treatment considerations are discussed.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Examen de los efectos del tratamiento en el consumo problemático de alcohol entre miembros en servicio con trastorno de estrés postraumático CONSUMO PROBLEMÁTICO DE ALCOHOL DURANTE EL TRATAMIENTO DE TEPT El Trastorno de Estrés Postraumático (TEPT) y trastorno por uso de Alcohol son frecuentemente comórbidos y presentan desafíos significativos para el tratamiento. Desafortunadamente, desde el ataque terrorista del 11 de Septiembre del 2001 en los Estados Unidos, las tasas de TEPT y consumo problemático de alcohol han aumentado significativamente entre los miembros en servicio activo. Las investigaciones previas en TEPT clásicamente han excluido a los participantes con abuso de sustancias actual. Sin embargo, existen algunas investigaciones que examinan los tratamientos en forma independiente para TEPT y abuso de sustancias de forma consecutiva, concurrente o como potenciador de los tratamientos. Este estudio examinó la asociación entre consumo problemático de alcohol actual y tratamiento para TEPT entre 108 miembros en servicio activo con TEPT en un estudio aleatorizado controlado de terapia de procesamiento cognitivo grupal y terapia grupal centrada en el presente. Un puntaje total sobre 8 en el Test de Identificación de Trastornos por Uso de Alcohol definió el uso problemático de alcohol. A nivel basal, 25% de la muestra fue categorizada como bebedores problemáticos y los grupos de bebedores problemáticos y no problemáticos no difirieron en la severidad de los síntomas de TEPT, F(1, 106) = 0.08, p = .777.En el curso del tratamiento, los dos grupos tampoco difirieron significativamente en el cambio en la severidad de los síntomas de TEPT según la Lista de Chequeo para TEPT, F(1, 106) = 1.20, p = .280. El tratamiento para TEPT no aumentó el consumo problemático y el grupo del consumo problemático mostró reducciones significativas en el consumo de alcohol después del tratamiento del TEPT. Se discuten las limitaciones e implicancias para las consideraciones del tratamiento.

Caffeine Use in Military Personnel With PTSD: Prevalence and Impact on Sleep.

Background: Caffeine use is highly prevalent among active duty military personnel and can be beneficial to performance in the short term. However, regular caffeine use has been found to contribute to sleep disturbances, which are elevated among the significant number of military personnel with posttraumatic stress disorder (PTSD). The current study is the first to examine caffeine use and its relationship with sleep disturbances in military personnel seeking treatment for PTSD. Participants: Active duty military personnel (N = 366) who had returned from deployments to Afghanistan or Iraq and were seeking treatment for PTSD. Methods: Pearson correlations were used to examine the relationships between caffeine use, sleep disturbances, and PTSD symptom clusters. Results: The majority of the sample (89%) reported some caffeine use, with coffee being the largest contributor to total caffeine intake. Contrary to hypotheses, higher caffeine use was associated with lower insomnia symptom severity; follow-up analysis indicated that this was due to elevated insomnia symptom severity in those reporting no caffeine use. Caffeine use was not associated with any other measures of sleep disturbance or with PTSD symptoms. Conclusions: Caffeine use was not associated with greater reported sleep disturbances in this sample, possibly because those with elevated insomnia symptom severity abstained from any caffeine, or because insomnia symptoms were elevated in this sample.

Use of crisis management interventions among suicidal patients: Results of a randomized controlled trial.

BACKGROUND: Previous research supports the efficacy of the crisis response plan (CRP) for the reduction of suicidal behaviors as compared to treatment as usual (TAU). Patient perspectives and use of the CRP, and their relationship to later suicidal thoughts, remain unknown. METHODS: A secondary analysis of a randomized clinical trial comparing a standard CRP (S-CRP), a CRP enhanced with reasons for living (E-CRP), and TAU in a sample of 97 active-duty U.S. Army personnel was conducted. Participants were asked about their use, perceptions, and recall of each intervention. Generalized estimating equations were used to test the conditional effects of intervention use, perceptions, and recall on severity of suicide ideation during follow-up. RESULTS: Across all treatment groups, over 80% of participants retained their written CRP up to 6 months later, but less than 25% had the written plan in their physical possession at the time of each assessment. Participants in S-CRP and E-CRP were more likely to recall self-management strategies and sources of social support. Participants in TAU were more likely to recall use of professional healthcare services and crisis management services. All three interventions were rated as highly useful. More frequent use of the E-CRP and recall of its components were associated with significantly reduced suicide ideation as compared to TAU. CONCLUSIONS: Both CRPs have high acceptability ratings. The effect of both CRPs on reduced suicide ideation is associated with patient recall of components. More frequent use of the E-CRP is associated with larger reductions in suicide ideation.
