Massed cognitive processing therapy for combat-related posttraumatic stress disorder: Study design and methodology of a non-inferiority randomized controlled trial.

BACKGROUND: Posttraumatic stress disorder (PTSD) is prevalent among military personnel. Cognitive processing therapy (CPT) is identified as one of the most effective treatments for PTSD, although smaller effects have been found in military populations. High rates of dropout from treatment may contribute to reduced efficacy, and military personnel may face unique barriers to treatment completion. One method of improving efficacy may be to reduce dropout by decreasing the time required to receive a full dose of treatment. This paper describes the design and methodology of the first randomized clinical trial testing whether CPT delivered in an intensive format is non-inferior to standard delivery of CPT. METHOD: Participants are 140 active duty service members randomized to receive CPT in a 5-day combined group and individual intensive outpatient format (MCPT) or standard CPT (delivered individually twice weekly over 6 weeks). Participants are assessed at baseline, and 1 month, 4 months, and 1 year following the conclusion of the therapy. Reduction in PTSD symptomatology is the primary outcome of interest. Secondary outcomes include comorbid psychological symptoms, health, and functioning. A secondary objective is to examine predictors of treatment outcome to determine which service members benefit most from which treatment modality. CONCLUSION: If determined to be non-inferior, MCPT would provide an efficient and accessible modality of evidence-based PTSD treatment. This therapy format would improve access to care by reducing the amount of time required for treatment and improving symptoms and functioning more rapidly, thereby minimizing interference with work-related activities and disruption to the mission.

The use of practice assignments in cognitive processing therapy to promote cognitive and emotional change: A case study.

Cognitive processing therapy (CPT) is a first-line treatment for posttraumatic stress disorder (PTSD). The primary goals of CPT are to identify and challenge dysfunctional cognitions resulting from the trauma to promote a more balanced set of beliefs and reduce manufactured emotions; encouraging expression of natural emotions further promotes symptom improvement. Between-session assignments (homework) are an integral part of learning and practicing the skills developed during CPT, and these assignments are theorized to reinforce the proposed mechanisms of symptom change. This article begins with a brief description of the theoretical foundations of CPT and an overview of the session content of the CPT protocol, followed by a case study illustrating the use of CPT with the written account (CPT + A) with a survivor of childhood sexual assault. Although the client demonstrated some avoidance, her successful completion of practice assignments throughout treatment allowed her to identify and examine thoughts contributing to feelings of guilt and self-blame as well as negative beliefs about the world. She was able to reduce her assimilated and overaccommodated stuck points to form a more balanced view of the trauma, and also process her natural emotions, resulting in a significant reduction of PTSD symptoms. The role of homework at each session and how the assignments addressed the proposed mechanisms of change in CPT are discussed, and recommendations to increase clients' engagement in practice assignments in CPT are provided.

DSM-5 criterion-a-based trauma types in service members and veterans seeking treatment for posttraumatic stress disorder.

OBJECTIVE: In posttraumatic stress disorder (PTSD), the assumption of the equipotentiality of traumas ignores potentially unique contexts and consequences of different traumas. Accordingly, Stein et al. (2012) developed a reliable typing scheme in which assessors categorized descriptions of traumatic events into six "types": life threat to self (LTS), life threat to other, aftermath of violence (AV), traumatic loss, moral injury by self (MIS), and moral injury by other (MIO). We extended this research by validating the typing scheme using participant endorsements of type, rather than assesor-based types. We examined the concordance of participant and assesor types, frequency, and validity of participant-based trauma types by examining associations with baseline mental and behavioral health problems. METHOD: Interviewers enrolled military personnel and veterans (N = 1,443) in clinical trials of PTSD and helped them select the most currently distressing Criterion-A trauma. Participants and, archivally, assessors typed the distressing aspect(s) of this experience. RESULTS: AV was the most frequently participant-endorsed type, but LTS was the most frequently rated worst part of an event. Although participants endorsed MIS and MIO the least frequently, these were associated with worse mental and behavioral health problems. The agreement between participants and assessors regarding the worst part of the event was poor. CONCLUSION: Because of discrepancies between participant and assessor typologies, clinical researchers should use participants' ratings, and these should trump assessor judgment. Differences in pretreatment behavioral and mental health problems across some participant-endorsed trauma types partially support the validity of the participant ratings.

A comparison of the CAPS-5 and PCL-5 to assess PTSD in military and veteran treatment-seeking samples.

Background: This study was an examination of the puzzling finding that people assessed for symptoms of posttraumatic stress disorder (PTSD) consistently score higher on the self-report PTSD Checklist for DSM-5 (PCL-5) than the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). Both scales purportedly assess PTSD severity with the same number of items, scaling, and scoring range, but differences in scores between measures make outcomes difficult to decipher.Objective: The purpose of this study was to examine several possible psychometric reasons for the discrepancy in scores between interview and self-report.Method: Data were combined from four clinical trials to examine the baseline and posttreatment assessments of treatment-seeking active duty military personnel and veterans.Results: As in previous studies, total scores were higher on the PCL-5 compared to the CAPS-5 at baseline and posttreatment. At baseline, PCL-5 scores were higher on all 20 items, with small to large differences in effect size. At posttreatment, only three items were not significantly different. Distributions of item responses and wording of scale anchors and items were examined as possible explanations of the difference between measures. Participants were more likely to use the full range of responses on the PCL-5 compared to interviewers.Conclusions: Suggestions for improving the congruence between these two scales are discussed. Administration of interviews by trained assessors can be resource intensive, so it is important that those assessing PTSD severity are afforded confidence in the equivalence of their assessment of PTSD regardless of the assessment method used.

The purpose of this study was to examine two commonly used measures of posttraumatic stress disorder, the Clinician-Administered PTSD Scale (CAPS-5), an interview measure, and the PTSD Checklist (PCL-5), a self-report measure, to explore discrepancies in scores.Both measures have the same number of items and range of scores assessing the identical 20 symptoms of PTSD, yet higher scores are reported on the PCL-5.It appears that the differences in wording of the anchors may contribute to discrepancies in scoring.Addressing these problems would allow for a better match in scoring between scales.

Self-reported sleep problems in active-duty US Army personnel receiving posttraumatic stress disorder treatment in group or individual formats: secondary analysis of a randomized clinical trial.

STUDY OBJECTIVES: Sleep disturbances are common in military personnel with posttraumatic stress disorder (PTSD) and may persist following treatment. This study examined service members seeking treatment for PTSD, reporting insomnia symptoms, nightmares, excessive daytime sleepiness, and potential obstructive sleep apnea at baseline and the impact of sleep disturbances on a course of PTSD treatment. METHODS: In this secondary analysis, sleep was evaluated in 223 service members who participated in a randomized clinical trial comparing Cognitive Processing Therapy for PTSD delivered in individual or group formats. Sleep assessments included the Insomnia Severity Index, the Trauma-Related Nightmare Survey, and Epworth Sleepiness Scale administered at baseline and 2 weeks posttreatment. RESULTS: Following PTSD treatment, there were significant improvements for insomnia symptoms (MΔ = -1.49; d = -0.27), nightmares (MΔ = -0.35; d = -0.27), and excessive daytime sleepiness (MΔ = -0.91; d = -0.16). However, mean scores remained in clinical ranges at posttreatment. Participants with baseline insomnia symptoms had worse PTSD severity throughout treatment. Participants with baseline excessive daytime sleepiness or probable obstructive sleep apnea had greater PTSD severity reductions when treated with Cognitive Processing Therapy individually vs. in a group. Those with insomnia symptoms, nightmare disorder, and sleep apnea had greater depressive symptoms throughout treatment. CONCLUSIONS: Insomnia symptoms, nightmares, and excessive daytime sleepiness were high at baseline in service members seeking treatment for PTSD. While sleep symptoms improved with PTSD treatment, these sleep disorders were related to worse treatment outcomes with regards to symptoms of PTSD and depression. Individual Cognitive Processing Therapy is recommended over group Cognitive Processing Therapy for patients with either excessive daytime sleepiness or probable obstructive sleep apnea.

Psychometric Properties of the Self-Injurious Thoughts and Behaviors Interview-Short Form Among U.S. Active Duty Military Service Members and Veterans.

We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater reliability and good convergent and discriminant validity. The measurement properties of the SITBI-SF were comparable across service members and veterans. Approximately 8% of participants who denied a history of suicidal ideation on the SITBI-SF reported suicidal ideation on a separate self-report questionnaire (i.e., discordant responders). Discordant responders reported significantly higher levels of PTSD symptoms than those who denied suicidal ideation on both response formats. Findings suggest that the SITBI-SF is a reliable and valid interview-based measure of suicide-related thoughts and behaviors for use with military service members and veterans. Suicide risk assessment might be optimized if the SITBI-SF interview is combined with a self-report measure of related constructs.

Treatment responder status and time to response as a function of hazardous drinking among active-duty military receiving variable-length cognitive processing therapy for posttraumatic stress disorder.

OBJECTIVE: A common concern is whether individuals with posttraumatic stress disorder (PTSD) and hazardous drinking will respond to PTSD treatment or need a higher dose. In a sample of active-duty military, we examined the impact of hazardous drinking on cognitive processing therapy (CPT) outcomes and whether number of sessions to reach good end-state or dropout differed by drinking status. METHOD: Participants included 127 service members participating in a clinical trial of variable-length CPT. The Quick Drinking Screen was used to characterize drinking. Participants were categorized as treatment responders when they reached good end-state (<20 on the PTSD Checklist for DSM-5) or nonresponders if they completed 24 sessions or 18 weeks of treatment without good end-state. Survival analyses were used to compare time to dropout or good end-state between those with and without hazardous drinking. RESULTS: Those with hazardous drinking were as likely as those without to reach good end-state and no more likely to drop out. There were no differences in number of sessions to reach good end-state or dropout. On a gold-standard assessment, those with hazardous drinking evidenced more PTSD symptom reduction than those without. The overall proportion of participants with hazardous drinking decreased (30.7% to 18.6%), as did mean number of drinks per drinking day and drinks on the heaviest drinking day among those initially drinking hazardously. CONCLUSIONS: Results support using CPT for military personnel with PTSD and hazardous drinking and indicate that those with hazardous drinking can benefit from PTSD treatment without additional treatment sessions.

Hyperarousal symptoms linger after successful PTSD treatment in active duty military.

OBJECTIVE: Evidence-based psychotherapies are efficacious at reducing posttraumatic stress disorder (PTSD) symptoms, but military and veteran samples improve less than civilians. The objective of this secondary analysis of two clinical trials of cognitive processing therapy (CPT) was to determine if hyperarousal symptoms were more resistant to change compared with other PTSD symptom clusters in active duty service members. METHOD: Service members completed the PTSD Checklist for the DSM-5 (PCL-5) pre- and post-CPT. Symptoms were coded present if rated 2 (moderate) or higher on a 0-4 scale. Cutoffs for reliable and clinically significant change classified 21%, 18%, and 61% of participants as recovered, improved, and suboptimal responders, respectively. Data analyses focused on the posttreatment status of symptoms that were present at baseline to determine their persistence as a function of treatment outcome. Generalized linear mixed effects models with items treated as a repeated measure estimated the proportions who continued to endorse each symptom and compared hyperarousal symptoms with symptoms in other clusters. RESULTS: Among improved participants, the average hyperarousal symptom was present in 69% compared with 49% for symptoms in other clusters (p < .0001). Among recovered patients, hyperarousal symptoms were present for 26%, while symptoms in the reexperiencing (2%), avoidance (3%), and negative alterations (4%) clusters were almost nonexistent (p < .0001). CONCLUSIONS: Even among service members who recovered from PTSD after CPT, a significant minority continue to report hyperarousal symptoms while other symptoms remit. Hyperarousal symptoms may require additional treatment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Implicit trauma identity associations in treatment-seeking U.S. military personnel do not predict or change in response to cognitive processing therapy for PTSD.

OBJECTIVE: This study evaluated implicit associations (i.e., associations in memory that are automatically activated and difficult to control consciously) related to trauma and one's self in the context of a clinical trial for active duty service members seeking treatment for posttraumatic stress disorder (PTSD). Previous studies with nontreatment-seeking community samples found that implicit trauma identity associations were associated with PTSD symptoms even after controlling for amount of trauma exposure and self-reported negative cognitions about the self. This study extended prior work by evaluating whether trauma-related implicit associations were associated with PTSD and depressive symptoms in a clinical sample seeking treatment for PTSD, predicted PTSD treatment response, or changed over the course of treatment. METHOD: This secondary analysis examined implicit trauma identity associations using data from a clinical trial evaluating a variable-length adaptation of cognitive processing therapy for military personnel. Participants were 127 active duty U.S. military personnel (13.4% women) seeking PTSD treatment. Implicit trauma identity associations were evaluated at baseline and posttreatment. Study hypotheses and data analysis plan were preregistered. RESULTS: Contrary to predictions, baseline implicit trauma identity associations were not significantly associated with baseline PTSD or depressive symptoms and did not predict treatment response. Implicit trauma identity associations did not change significantly in response to treatment. CONCLUSIONS: More tailoring of implicit trauma measures for military personnel and/or treatment-seeking patients may be needed. The measure may lack sensitivity to change in response to treatment and have reduced utility in treatment-seeking samples with high symptom burden and less variability in symptoms.

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.

STRONG STAR and the Consortium to Alleviate PTSD: Shaping the future of combat PTSD and related conditions in military and veteran populations.

The STRONG STAR Consortium (South Texas Research Organizational Network Guiding Studies on Trauma and Resilience) and the Consortium to Alleviate PTSD are interdisciplinary and multi-institutional research consortia focused on the detection, diagnosis, prevention, and treatment of combat-related posttraumatic stress disorder (PTSD) and comorbid conditions in military personnel and veterans. This manuscript outlines the consortia's state-of-the-science collaborative research model and how this can be used as a roadmap for future trauma-related research. STRONG STAR was initially funded for 5 years in 2008 by the U.S. Department of Defense's (DoD) Psychological Health and Traumatic Brain Injury Research Program. Since the initial funding of STRONG STAR, almost 50 additional peer-reviewed STRONG STAR-affiliated projects have been funded through the DoD, the U.S. Department of Veterans Affairs (VA), the National Institutes of Health, and private organizations. In 2013, STRONG STAR investigators partnered with the VA's National Center for PTSD and were selected for joint DoD/VA funding to establish the Consortium to Alleviate PTSD. STRONG STAR and the Consortium to Alleviate PTSD have assembled a critical mass of investigators and institutions with the synergy required to make major scientific and public health advances in the prevention and treatment of combat PTSD and related conditions. This manuscript provides an overview of the establishment of these two research consortia, including their history, vision, mission, goals, and accomplishments. Comprehensive tables provide descriptions of over 70 projects supported by the consortia. Examples are provided of collaborations among over 50 worldwide academic research institutions and over 150 investigators.

Efficacy of individual and group cognitive processing therapy for military personnel with and without child abuse histories.

Objective: Many clinicians question whether patients with a history of childhood trauma will benefit from trauma-focused treatment. In this secondary analysis, we examined whether reports of childhood abuse moderated the efficacy of cognitive processing therapy (CPT) for active-duty military with posttraumatic stress disorder (PTSD). Methods: Service members (N = 254, mean age 33.11 years, 91% male, 41% Caucasian) were randomized to receive individual or group CPT (n = 106 endorsing and n = 148 not endorsing history of childhood abuse). Outcomes included baseline cognitive-emotional characteristics [Posttraumatic Cognitions Inventory (PTCI), Trauma-Related Guilt Inventory (TRGI), Cognitive Emotion Regulation Questionnaire-Short Form (CERQ)], treatment completion, and symptom outcome (PTSD Checklist, Beck Depression Inventory-II). We predicted participants endorsing childhood abuse would have higher scores on the PTCI, TRGI, and CERQ at baseline, but be noninferior on treatment completion and change in PTSD and depression symptoms. We also predicted those endorsing childhood abuse would do better in individual CPT than those not endorsing abuse. Results: Those endorsing childhood abuse primarily experienced physical abuse. There were no baseline differences between service members with and without a history of childhood abuse (all p ≥ .07). Collapsed across treatment arms, treatment completion and symptom reduction were within the noninferiority margins for those endorsing versus not endorsing childhood abuse. History of abuse did not moderate response to individual versus group CPT. Conclusions: In this primarily male, primarily physically abused sample, active-duty military personnel with PTSD who endorsed childhood abuse benefitted as much as those who did not endorse abuse.

A Novel Approach to the Assessment of Fidelity to a Cognitive Behavioral Therapy for PTSD Using Clinical Worksheets: A Proof of Concept With Cognitive Processing Therapy.

Fidelity monitoring is a critical indicator of psychotherapy quality and is central to successful implementation. A major barrier to fidelity in routine care is the lack of feasible, scalable, and valid measurement strategies. A reliable, low-burden fidelity assessment would promote sustained implementation of cognitive behavioral therapies (CBTs). The current study examined fidelity measurement for cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) using clinical worksheets. External raters evaluated patient worksheets done as a part of treatment, both guided by the therapist and completed independently as homework. Results demonstrated that fidelity ratings from CPT session worksheets were feasible and efficient. Notably, they were strongly correlated with observer ratings of the fidelity of CPT strategies that were present on the worksheets. Agreement among ratings conducted by individuals with a range of experience with CPT was acceptable to high. There was not a main effect of therapist-guided, in-session worksheet ratings on PTSD symptom change. However, patient competence in completing worksheets independently was associated with greater PTSD symptom decline and in-session, therapist-guided worksheet completion was associated with larger symptom decreases among patients with high levels of competence. With further research and refinement, rating of worksheets may be an efficient way to examine therapist and patient skill in key CPT elements, and their interactions, compared to the gold standard of observer ratings of therapy video-recordings. Additional research is needed to determine if worksheets are an accurate and scalable alternative to gold standard observer ratings in settings in which time and resources are limited.

Variable-length Cognitive Processing Therapy for posttraumatic stress disorder in active duty military: Outcomes and predictors.

Cognitive Processing Therapy (CPT) is an evidence-based therapy recommended for posttraumatic stress disorder (PTSD). However, rates of improvement and remission are lower in veterans and active duty military compared to civilians. Although CPT was developed as a 12-session therapy, varying the number of sessions based on patient response has improved outcomes in a civilian study. This paper describes outcomes of a clinical trial of variable-length CPT among an active duty sample. Aims were to determine if service members would benefit from varying the dose of treatment and identify predictors of treatment length needed to reach good end-state (PTSD Checklist-5 ≤ 19). This was a within-subjects trial in which all participants received CPT (N = 127). Predictor variables included demographic, symptom, and trauma-related variables; internalizing/externalizing personality traits; and readiness for change. Varying treatment length resulted in more patients achieving good end-state. Best predictors of nonresponse or needing longer treatment were pretreatment depression and PTSD severity, internalizing temperament, being in precontemplation stage of readiness for change, and African American race. Controlling for differences in demographics and initial PTSD symptom severity, the outcomes using a variable-length CPT protocol were superior to the outcomes of a prior study using a fixed, 12-session CPT protocol.

Identifying suicidal subtypes and dynamic indicators of increasing and decreasing suicide risk in active duty military personnel: Study protocol.

OBJECTIVES: Several recent studies have demonstrated that posttraumatic stress disorder (PTSD) and insomnia treatments are associated with significant reductions in suicidal ideation (SI) among service members. However, few investigations have evaluated the manner in which suicide risk changes over time among military personnel receiving PTSD or insomnia treatments. This paper describes the study protocol for a project with these aims: (1) explore potential genetic, clinical, and demographic subtypes of suicide risk in a large cohort of deployed service members; (2) explore subtype change in SI as a result of evidence-based psychotherapies for PTSD and insomnia; (3) evaluate the speed of change in suicide risk; and (4) identify predictors of higher- and lower-risk for suicide. METHODS: Active duty military personnel were recruited for four clinical trials (three for PTSD treatment and one for insomnia treatment) and a large prospective epidemiological study of deployed service members, all conducted through the South Texas Research Organizational Network Guiding Studies on Trauma and Resilience (STRONG STAR Consortium). Participants completed similar measures of demographic and clinical characteristics and subsets provided blood samples for genetic testing. The primary measures that we will analyze are the Beck Scale for Suicide Ideation, Beck Depression Inventory, and the PTSD Checklist for DSM-IV. DISCUSSION: Results from this study will offer new insights into the presence of discrete subtypes of suicide risk among active duty personnel, changes in risk over time among those subtypes, and predictors of subtypes. Findings will inform treatment development for military service members at risk for suicide.

Predictors of Treatment Outcome in Group or Individual Cognitive Processing Therapy for Posttraumatic Stress Disorder Among Active Duty Military.

Background: The purpose of this study was to examine demographic, psychological, military, and deployment variables that might predict posttraumatic stress disorder (PTSD) symptom improvement in a sample of active duty service members who received either group or individual cognitive processing therapy (CPT). Methods: Data were analyzed from 165 active duty service members with pre- and posttreatment data participating in a randomized controlled trial comparing group with individual CPT. Pretreatment variables were examined as predictors of change in PTSD severity from baseline to posttreatment, assessed using the PTSD Symptom Scale-Interview Version (PSS-I). Predictors of PSS-I change were first evaluated using Pearson correlations, followed by partial and multiple correlations to clarify which associations remained when effects of other predictors were controlled. Multiple regression analyses were used to test for interactions between pretreatment variables and treatment format. Results: Only age was a significant predictor of PTSD symptom change after controlling for other variables and statisitically correcting for testing multiple variables. There was also an interaction between age and treatment format. Conclusions: Younger participants had greater symptom improvement, particularly if they received individual treatment. Other pretreatment variables did not predict outcome. CPT appears to be robust across most pretreatment variables, such that comorbid disorders, baseline symptom severity, and suicidal ideation do not interfere with application of CPT. However, individual CPT may be a better option particularly for younger service members.

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.

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.

Conceptualizing comorbid PTSD and depression among treatment-seeking, active duty military service members.

BACKGROUND: Among active duty service members and veterans with PTSD, depression is the most commonly diagnosed comorbid psychiatric condition. More research is warranted to investigate the relationship between PTSD and depression to improve treatment approaches. Byllesby et al. (2017) used confirmatory factor analyses in a sample of trauma-exposed combat veterans with PTSD and found that only the general distress factor, and not any specific symptom cluster of PTSD, predicted depression. This study seeks to replicate Byllesby et al. (2017) in a sample of treatment-seeking active duty soldiers. METHODS: Confirmatory factor analyses, bifactor modeling, and structural equation modeling (SEM) were used with data gathered at pretreatment and posttreatment as part of a large randomized clinical trial. RESULTS: Confirmatory factor analyses and bifactor modeling demonstrated that PTSD symptom clusters, Negative Alterations in Cognition and Mood (NACM) and Alterations in Arousal and Reactivity (AAR), as well as the general distress factor significantly predicted depression at pretreatment and posttreatment. LIMITATIONS: The current study was predominantly male, limiting the generalizability to female service members with PTSD. Also, self-report measures were used, which may introduce response-bias. CONCLUSIONS: The current study did not replicate Byllesby et al. (2017). Results demonstrated that the relationship between PTSD and depression among active duty service members can be explained by both transdiagnostic factors and disorder-specific symptoms.
