Imagining emotional future events in PTSD: clinical and neurocognitive correlates.

Emotional future thinking serves important functions related to goal pursuit and emotion regulation but has been scantly studied in posttraumatic stress disorder (PTSD). The current study sought to characterize emotional future thinking in PTSD and to identify clinical and neurocognitive profiles associated with potential alterations in the level of detail in narratives of imagined future events. Fifty-eight, trauma-exposed, war-zone veterans, who were classified into current PTSD, past PTSD, and no-PTSD groups, were asked to vividly imagine future events in response to positive and negative cue words occurring in the near and distant future. These narratives were scored for internal (i.e., pertaining to the main event) and external (i.e., tangential to the main event) details. Participants also performed neurocognitive tasks of generative ability, working memory, and relational verbal memory. Linear mixed modeling revealed that the current and past PTSD groups generated fewer internal details than the no-PTSD group across positive and negative cue words and across temporal proximity. Partial least squares analysis revealed that symptom severity for all PTSD clusters was inversely associated with production of internal details, albeit with the association relatively weaker for intrusion symptoms. Among the neurocognitive tasks, only relational verbal memory was associated with production of internal details. These findings suggest, as predicted, that functional avoidance may underlie reduced detail generation but also point to potential additional mechanisms to be further investigated. That future event simulation remains overgeneral even when PTSD symptoms abate highlights the importance of addressing alterations in future thinking in this population.

Early predictors of chronic posttraumatic stress disorder symptom trajectories in U.S. Army soldiers deployed to the Iraq war zone.

The course of posttraumatic stress disorder (PTSD) symptoms varies among veterans of war zones, but sources of variation in long-term symptom course remain poorly understood. Modeling of symptom growth trajectories facilitates the understanding of predictors of individual outcomes over time. Although growth mixture modeling (GMM) has been applied to military populations, few studies have incorporated both predeployment and follow-up measurements over an extended time. In this prospective study, 1,087 U.S. Army soldiers with varying military occupational specialties and geographic locations were assessed before and after deployment to the Iraq war zone, with long-term follow-up assessment occurring at least 5 years after return from deployment. The primary outcome variable was the PTSD Checklist-Civilian Version summary score. GMM yielded four latent profiles, characterized as primarily asymptomatic (n = 194, 17.8%); postdeployment worsening symptoms (n = 84, 7.7%); mild symptoms (n = 320, 29.4%); and preexisting, with a chronic postdeployment elevation of symptoms (n = 489, 45.0%). Regression models comparing the primarily asymptomatic class to the symptomatic classes revealed that chronic symptom classes were associated with higher degrees of stress exposure, less predeployment social support, military reservist or veteran status at the most recent assessment, and poorer predeployment visual memory, ORs = 0.98-2.90. PTSD symptom course varies considerably over time after military deployment and is associated with potentially modifiable biopsychosocial factors that occur early in its course in addition to exposures and military status.

Associations Among Increases in Posttraumatic Stress Symptoms, Neurocognitive Performance, and Long-Term Functional Outcomes in U.S. Iraq War Veterans.

Cross-sectional research suggests that posttraumatic stress symptoms (PTSS) among war zone veterans are associated with functional impairment and poor quality of life. Less is known about the long-term functional repercussions of PTSS. This study of Iraq War veterans examined the associations between increases in PTSS and long-term functional outcomes, including the potential contributions of neurocognitive decrements. Service members and veterans (N = 594) completed self-report measures of functioning and PTSS severity before Iraq War deployment and again after their return (M = 9.3 years postdeployment). Some participants (n = 278) also completed neurocognitive testing at both times. Multiple regression analyses with the full sample-adjusted for TBI, demographic characteristics, military variables, and predeployment PTSS and functioning-revealed that increased PTSS severity over time was significantly associated with unemployment, aOR = 1.04, 95% CI [1.03, 1.06]; poorer work performance; and poorer physical, emotional, and cognitive health-related functioning at long-term follow-up, f2 s = 0.37-1.79. Among participants who completed neurocognitive testing, a decline in select neurocognitive measures was associated with poorer functioning; however, neurocognitive decrements did not account for associations between increased PTSS and unemployment, aOR = 1.04, 95% CI [1.02, 1.07], with the size and direction upheld after adding neurocognitive variables, or poorer functional outcomes, with small increases after adding neurocognitive measures to the models, f2 s = 0.03-0.10. War zone veterans experiencing long-term increased PTSS and/or neurocognitive decrements may be at elevated risk for higher-level functional impairment over time, suggesting that early PTSS management may enhance long-term functioning.

Associations of warzone veteran mental health with partner mental health and family functioning: Family Foundations Study.

INTRODUCTION: Warzone participation is associated with increased risk of stress-related psychopathology, including posttraumatic stress disorder (PTSD) and depression. Prior research suggests that the mental health of spouses of warzone veterans (WZVs) is linked to that of their partners. Additionally, PTSD among WZVs has been associated with marital dysfunction. Less is known about the effects of depression among WZVs on partner mental health and family relationships. We sought in this study to examine associations between WZV PTSD and depression and partner mental health and relationship outcomes. METHODS: Using a nationally dispersed sample of Iraq and Afghanistan veterans and their married and unmarried intimate partners, 245 dyads completed structured psychiatric interviews and psychometric surveys assessing family functioning and relationship aggression. RESULTS: Adjusted regression analyses indicated that depression among WZVs was associated with partner depression and anxiety disorders. WZV PTSD and depression were also associated with partner-reported relationship dysfunction, dissatisfaction, and communication issues, and higher rates of intimate partner aggression victimization and perpetration. CONCLUSIONS: Mental health consequences of war extend beyond WZVs to the mental health of their intimate partners and their relationships with intimate partners.

Associations Between Trauma-Related Rumination and Symptoms of Posttraumatic Stress and Depression in Treatment-Seeking Female Veterans.

Trauma-related rumination is a cognitive style characterized by repetitive negative thinking about the causes, consequences, and implications of a traumatic experience. Frequent trauma-related rumination has been linked to posttraumatic stress disorder (PTSD) and depression in civilian samples but has yet to be examined among military veterans. This study extended previous research by examining trauma-related rumination in female veterans who presented to a Veterans Affairs women's trauma recovery clinic (N = 91). The study had two main aims: (a) to examine associations between trauma-related rumination and specific PTSD symptoms, adjusting for the overlap between trauma-related rumination and other relevant cognitive factors, such as intrusive trauma memories and self-blame cognitions; and (b) to assess associations between trauma-related rumination, PTSD, and depression, adjusting for symptom comorbidity. At intake, patients completed a semistructured interview and self-report questionnaires. Primary diagnoses were confirmed via medical record review. Trauma-related rumination was common, with more than 80% of patients reporting at least sometimes engaging in this cognitive style in the past week. After adjusting for other relevant cognitive factors, trauma-related rumination was significantly associated with several specific PTSD symptoms, rp s = .33-.48. Additionally, the severity of trauma-related rumination was associated with overall PTSD symptom severity, even after adjusting for comorbid depression symptoms, rp 2 = .35. In contrast, the association between trauma-related rumination and depressive symptom severity was not significant after adjusting for comorbid PTSD symptoms, rp 2 = .008. These results highlight trauma-related rumination as a unique contributing factor to the complex clinical presentation for a subset of trauma-exposed veterans.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Asociaciones entre la rumiación relacionada con el trauma y síntomas de estrés postraumático y depresión en Mujeres Veteranas en busca de tratamiento RUMINACIÓN RELACIONADA CON EL TRAUMA EN MUJERES VETERANAS La rumiación relacionada con el trauma es un estilo cognitivo caracterizado por pensamientos negativos repetitivos sobre las causas, consecuencias e implicaciones de una experiencia traumática. Frecuentemente la rumiación relacionada con el trauma se ha relacionado con el trastorno de estrés postraumático (TEPT) y la depresión en muestras de civiles, pero aún no se ha examinado entre los veteranos militares. Este estudio extendió la investigación previa al examinar la rumiación relacionada con el trauma en mujeres veteranas que acudieron a una clínica de recuperación de trauma para mujeres del VA (N = 91). El estudio tenía dos objetivos principales: examinar (a) las asociaciones entre la rumiación relacionada con el trauma y los síntomas específicos de TEPT, ajustándose a la superposición entre la rumiación relacionada con el trauma y otros factores cognitivos relevantes, como los recuerdos intrusivos del trauma y las cogniciones de auto-culpa; y (b) asociaciones entre rumiación relacionada con el trauma, TEPT y depresión, ajustando la comorbilidad de los síntomas. En el momento del ingreso, los pacientes completaron una entrevista semiestructurada y cuestionarios de autoinforme. Los diagnósticos primarios fueron confirmados a través de la revisión de la historia clínica. La rumiación relacionada con el trauma fue común, con más del 80% de los pacientes que informaron que al menos a veces se involucraron en este estilo cognitivo en la última semana. Después de ajustar otros factores cognitivos relevantes, la rumiación relacionada con el trauma se asoció significativamente con varios síntomas específicos de TEPT, rp s = .33 - .48. Además, la gravedad de la rumiación relacionada con el trauma se asoció con la gravedad general de los síntomas del TEPT incluso después de ajustar los síntomas de depresión comórbida, rp 2 = .35. En contraste, la asociación entre la rumiación relacionada con el trauma y la gravedad de los síntomas depresivos no fue significativa después de ajustar los síntomas de trastorno de estrés postraumático comórbido, rp 2 = .008. Estos resultados resaltan la rumiación relacionada con el trauma como un factor único contribuyente a la compleja presentación clínica para un subconjunto de veteranas expuestas a traumas.

Longitudinal Associations among Posttraumatic Stress Disorder Symptoms, Traumatic Brain Injury, and Neurocognitive Functioning in Army Soldiers Deployed to the Iraq War.

OBJECTIVES: Military deployment is associated with increased risk of adverse emotional and cognitive outcomes. Longitudinal associations involving posttraumatic stress disorder (PTSD), relatively mild traumatic brain injury (TBI), and neurocognitive compromise are poorly understood, especially with regard to long-term outcomes, and rigorous research is necessary to better understand the corresponding relationships. The objective of this study was to examine short-term and long-term (>5 years) longitudinal associations among PTSD, neurocognitive performance, and TBI following military deployment. METHODS: In this prospective study, N=315 U.S. Army soldiers were assessed at military installations before (2003-2005) and after (2004-2006) an index deployment to the Iraq War, and again an average of 7.6 years later (2010-2014) as a nationally dispersed cohort of active duty soldiers, reservists, and veterans. Thus, the study design allowed for two measurement intervals over which to examine changes. All assessments included the PTSD Checklist, civilian version, and individually-administered performance-based neurocognitive tests. TBI history was derived from clinical interview. RESULTS: Autoregressive analyses indicated that visual reproduction scores were inversely related to subsequent PTSD symptom severity at subsequent assessments. Conversely, increases in PTSD symptom severity over each measurement interval were associated with poorer verbal and/or visual recall at the end of each interval, and less efficient reaction time at post-deployment. TBI, primarily mild in this sample, was associated with adverse PTSD symptom outcomes at both post-deployment and long-term follow-up. CONCLUSIONS: These results suggest longitudinal relationships among PTSD symptoms, TBI, and neurocognitive decrements may contribute to sustained emotional and neurocognitive symptoms over time.

Traumatic Brain Injury and Posttraumatic Stress Disorder: Conceptual, Diagnostic, and Therapeutic Considerations in the Context of Co-Occurrence.

The events leading to traumatic brain injury (TBI) are often psychologically traumatic (e.g., motor vehicle accidents) or occur within a broader context of psychological trauma, such as military combat or recurrent interpersonal violence. In such cases, posttraumatic stress disorder (PTSD) may develop and serve to complicate TBI recovery. Likewise, brain trauma may impede emotional resolution following psychological trauma exposure. This article addresses comorbid PTSD and TBI, including the epidemiology of PTSD following TBI; the clinical presentation of the comorbidity; potential mechanisms that complicate recovery from psychological trauma and TBI when they co-occur; and considerations for the clinical management of PTSD in the context of TBI, including implications for both psychosocial and psychopharmacological PTSD treatments. Although the authors address the full spectrum of TBI severity, because PTSD more commonly co-occurs with mild TBI, compared with moderate and severe TBI, the authors focus in particular on mild TBI.

Neurocognitive and Information Processing Biases in Posttraumatic Stress Disorder.

PURPOSE OF REVIEW: We review recent research addressing neurocognitive and information processing abnormalities in posttraumatic stress disorder (PTSD), including studies informing direction of causality. We additionally consider neurocognition in the context of co-morbid mild traumatic brain injury (TBI) and psychosocial treatments for PTSD. RECENT FINDINGS: Learning, memory, attention, inhibitory functions, and information processing biases frequently accompany PTSD, reflecting potential bi-directional relationships with PTSD. Although mild TBI is associated with increased risk of PTSD development and maintenance, TBI does not typically contribute significantly to sustained neurocognitive deficits in individuals with PTSD. Whereas better learning and memory is associated with mildly enhanced response to psychosocial interventions, such interventions may also improve neurocognitive performance and can be effectively provided to patients with TBI history. PTSD is associated with cognitive abnormalities in processing both emotionally relevant and emotionally neutral information and, although mild, may underlie some PTSD symptom expression.

Prospective Examination of Early Associations of Iraq War Zone Deployment, Combat Severity, and Posttraumatic Stress Disorder with New Incident Medical Diagnoses.

War zone deployment and posttraumatic stress disorder (PTSD) have been associated with morbidity and mortality decades later. Less is known about the associations between these variables and the early emergence of medical disorders in war zone veterans. This prospective study of 862 U.S. Army soldiers (n = 569 deployed; n = 293 nondeployed) examined: (a) associations between Iraq War deployment status (deployed vs. nondeployed) and new medical diagnoses that emerged within six months after return from Iraq among all participants; and (b) associations between combat severity and PTSD symptoms, and new postdeployment medical diagnoses that emerged within 12 months after return from Iraq within deployed participants. New medical diagnoses were abstracted from diagnostic codes associated with clinical outpatient visits recorded within the Department of Defense Standard Ambulatory Data Record database. Combat severity was measured with the Combat Experiences module of the Deployment Risk and Resilience Inventory, and postdeployment posttraumatic stress disorder symptom severity was measured using the PTSD Checklist-Civilian. Neither deployment nor combat severity was associated with new medical diagnoses. However, among deployed soldiers, more severe PTSD symptoms were associated with increased risk for a new medical disorder diagnosis; every 10-point increase in PTSD symptoms increased odds of a new diagnosis by nearly 20% (odds ratio = 1.20). Results suggest that PTSD symptoms are associated with early morbidity in Iraq War veterans.

Traumatic brain injury clinical practice guidelines and best practices from the VA state of the art conference.

Management of symptoms following traumatic brain injury (TBI) can be complex and remains a high priority for Department of Defense (DoD) and Department of Veteran Affairs (VA). Concurrently, awareness of TBI in the public has increased. VA convened a State of the Art (SOTA) Conference to identify priorities for future research and promote best practices for TBI care. Scientific evidence of effective management of symptoms following TBI is expanding, and this evidence has been synthesized into Clinical Practice Guidelines (CPGs) and Clinical Practice Recommendations (CPRs). Knowledge gaps still exist and research efforts to address these gaps should include leveraging large administrative data sets and existing registries to determine effective treatments, investigate compliance of existing clinical care with CPGs and study limitations to determine modifiable vs. non-modifiable core tenants of the evidence-based treatments.

Longitudinal Examination of Posttraumatic Stress Disorder as a Long-Term Outcome of Iraq War Deployment.

The mental health toll of the Iraq and Afghanistan Wars on military veterans has been considerable, yet little is known about the persistence of these adverse outcomes, especially relative to predeployment status. We prospectively examined posttraumatic stress disorder (PTSD) as a long-term consequence of warzone deployment, integrating data collected from 2003-2014. In the Neurocognition Deployment Health Study, we measured PTSD symptoms in US Army soldiers before and shortly after Iraq War deployment. We used the PTSD Checklist-Civilian Version and a structured clinical interview (i.e., Clinician-Administered PTSD Scale) to reassess PTSD in 598 service members and military veterans a median of 7.9 years (interquartile range, 7.2-8.5 years) after an index Iraq deployment. At long-term follow-up, 24.7% (95% confidence interval (CI): 21.5, 28.4) of participants met the case definition for PTSD, which was an absolute increase of 14.2% from the percentage assessed postdeployment (10.5%; 95% CI: 7.8, 13.7) and of 17.3% from the percentage assessed predeployment (7.4%; 95% CI: 5.5, 9.8). These findings highlight that PTSD is an enduring consequence of warzone participation among contemporary military personnel and veterans. The largest increase in PTSD cases occurred between the postdeployment and long-term follow-up assessments, which suggests that adverse stress reactions cannot necessarily be expected to dissipate over time and actually may increase.

Prospective Associations Between Traumatic Brain Injury and Postdeployment Tinnitus in Active-Duty Marines.

OBJECTIVE: To examine whether cause, severity, and frequency of traumatic brain injury (TBI) increase risk of postdeployment tinnitus when accounting for comorbid posttraumatic stress disorder. DESIGN: Self-report and clinical assessments were done before and after an "index" deployment to Iraq or Afghanistan. SETTING, PARTICIPANTS, AND MEASURES: Assessments took place on Marine Corps bases in southern California and the VA San Diego Medical Center. Participants were 1647 active-duty enlisted Marine and Navy servicemen who completed pre- and postdeployment assessments of the Marine Resiliency Study. The main outcome was the presence of tinnitus at 3 months postdeployment. RESULTS: Predeployment TBI increased the likelihood of new-onset postdeployment tinnitus (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.28-2.70). Deployment-related TBIs increased the likelihood of postdeployment tinnitus (OR = 2.65; 95% CI, 1.19-5.89). Likelihood of new-onset postdeployment tinnitus was highest for those who were blast-exposed (OR = 2.93; 95% CI, 1.82-6.17), who reported moderate-severe TBI symptoms (OR = 2.22; 95% CI, 1.22-3.40), and who sustained multiple TBIs across study visits (OR = 2.27; 95% CI, 1.44-4.24). Posttraumatic stress disorder had no effect on tinnitus outcome. CONCLUSIONS: Participants who were blast-exposed, sustained multiple TBIs, and reported moderate-severe TBI symptoms were most at risk for new-onset tinnitus.

Consistency of Recall for Deployment-Related Traumatic Brain Injury.

OBJECTIVE: To examine the temporal consistency of self-reported deployment-related traumatic brain injury (TBI) and its association with posttraumatic stress disorder (PTSD) symptom severity. SETTING: In-person interviews at US Army installations (postdeployment); phone interviews (long-term follow-up). PARTICIPANTS: A total of 378 US Army soldiers and veterans deployed to Iraq; 14.3% (n = 54) reported TBI with loss of consciousness during an index deployment. DESIGN: Participants were evaluated after returning from deployment and again 5 to 9 years later. MAIN MEASURES: Temporal consistency of TBI endorsement based on TBI screening interviews; PTSD Checklist, Civilian Version. RESULTS: The concordance of deployment-related TBI endorsement from the postdeployment to long-term follow-up assessment was moderate (κ = 0.53). Of the 54 participants reporting (predominantly mild) TBI occurring during an index deployment, 32 endorsed TBI inconsistently over time. More severe PTSD symptoms at postdeployment assessment were independently associated with discordant reporting (P = .0004); each 10-point increase in PCL scores increasing odds of discordance by 69% (odds ratio = 1.69; 95% confidence interval, 1.26-2.26). CONCLUSIONS: Deployment-related TBI may not be reported reliably over time, particularly among war-zone veterans with greater PTSD symptoms. Results of screening evaluations for TBI history should be viewed with caution in the context of PTSD symptom history.

Mild Traumatic Brain Injury, PTSD, and Psychosocial Functioning Among Male and Female U.S. OEF/OIF Veterans.

This study examined the unique and combined relationship between mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) with psychosocial functioning in a cohort of 1,312 U.S. male and female veterans of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF) enrolled in the Veterans After-Discharge Longitudinal Registry (Project VALOR). We assessed mTBI with structured screening questions reflective of current TBI classification standards and PTSD via the SCID-IV PTSD module; all other variables were assessed by self-report questionnaires. We identified significant diagnostic group differences in psychosocial functioning for both sexes. Individuals with PTSD, with or without a history of mTBI, reported significantly worse psychosocial functioning than individuals with mTBI alone or neither mTBI nor PTSD (males, η(2) p = .11, p < .001; females, η(2) p = .14, p < .001), even after adjusting for demographics and severity of chronic pain. The results suggested that veterans experiencing PTSD, regardless of whether they had a history of mTBI, were at increased risk for long-term psychosocial impairment. Further research examining possible benefits from improved access to resources and treatment to address these needs would be valuable.

Consistency of Reporting for Stressful Life Events Among Nondeployed Soldiers.

OBJECTIVES: Measurement of stress exposure is central to understanding military mental health outcomes. Although temporal stability of combat event reporting has been examined, less is known about the stability of reporting for noncombat events in military samples. Objectives are to examine consistency in reporting stressful life events in nondeployed U.S. Army soldiers and its association with posttraumatic stress disorder (PTSD) symptomatology. METHOD: Examined reporting consistency over approximately 8 months among 466 soldiers. Regression models examined factors associated with decreased, increased, and stable reporting. RESULTS: Stability of the number of events endorsed over time was high. However, item-level agreement was slight to moderate (kappas: .13-.54), with inconsistencies due primarily to decreased reporting. After adjusting for covariates and initial PTSD, second assessment PTSD was associated with increased and stable reporting. CONCLUSIONS: Inconsistent reporting extends beyond combat events to other stressful life events in military personnel and is associated with PTSD.

Prospective examination of cigarette smoking among Iraq-deployed and nondeployed soldiers: prevalence and predictive characteristics.

BACKGROUND: Identifying characteristics that influence smoking behavior among military personnel is critical to protect health and operational functioning. PURPOSE: This study prospectively examined rates of cigarette smoking and predictors of changes in smoking behavior as a function of Iraq deployment. METHODS: One thousand eighty-two US Army soldiers (n = 773 Iraq-deployed; n = 309 nondeployed) completed assessments at two sessions [time 1: April 2003-July 2004; time 2: May 2004-July 2004 (nondeployers); January 2005-September 2006 (deployers)]. RESULTS: Approximately 48 % of participants smoked at both time points, with 6 % initiating smoking and 6 % quitting. Smoking initiation was associated with warzone stress exposure; female gender and high military unit support predicted cessation. Military rank and alcohol use were associated with both smoking initiation and cessation. CONCLUSION: Findings highlight the potential benefits of targeting risk factors for cigarette smoking in comprehensive military health programs aimed at smoking prevention and cessation.

Traumatic brain injury, PTSD, and current suicidal ideation among Iraq and Afghanistan U.S. veterans.

Suicide is a prevalent problem among veterans deployed to Iraq and Afghanistan. Traumatic brain injury (TBI) and psychiatric conditions, such as posttraumatic stress disorder (PTSD), are potentially important risk factors for suicide in this population, but the literature is limited by a dearth of research on female veterans and imprecise assessment of TBI and suicidal behavior. This study examined 824 male and 825 female U.S. veterans who were enrolled in the baseline assessment of the Veterans After-Discharge Longitudinal Registry (Project VALOR), an observational registry of veterans with and without PTSD who deployed in support of the wars in Iraq and Afghanistan and were enrolled in the Veterans Affairs healthcare system. Results indicated that current depressive symptoms, PTSD, and history of prior TBI were all significantly associated with current suicidal ideation (Cohen's d = 0.91, Cramers' Vs = .19 and .08, respectively). After adding a number of variables to the model, including psychiatric comorbidity, TBI history was associated with increased risk of current suicidal ideation among male veterans only (RR = 1.55). TBI is an important variable to consider in future research on suicide among veterans of the wars in Iraq and Afghanistan, particularly among male veterans.

Associations between PTSD and temporal discounting: The role of future thinking.

BACKGROUND AND OBJECTIVES: Despite documented alterations in future thinking in posttraumatic stress disorder (PTSD), our understanding of how individuals with PTSD make future-oriented decisions is limited. We tested the hypothesis that increased discounting in association with PTSD reflects failure to spontaneously envision future rewarding situations. METHODS: Thirty-seven trauma exposed war-zone veterans completed a standard temporal discounting task as well as a temporal discounting task accompanied by episodic future thinking cues. RESULTS: Severity of PTSD symptoms was associated with preference for sooner, smaller rewards in the standard task. Consistent with our hypothesis, when participants engaged in future thinking, greater PTSD symptom severity was no longer associated with steeper discounting. Moreover, difficulty anticipating future events, as measured contemporaneously in a separate task (Verfaellie et al., 2024), mediated the relationship between PTSD symptom severity and degree of discounting in the standard task. Among PTSD symptom clusters, the severity of avoidance and negative alterations in cognition and mood was related to steeper discounting. Measures of depression and alcohol use were not associated with discounting. LIMITATIONS: The sample included mostly male, predominantly White veterans who experienced primarily combat-related trauma. CONCLUSIONS: PTSD-associated alterations in temporal discounting reflect failure to spontaneously imagine future positive events. Two common correlates of PTSD, depression and alcohol use, could not account for the observed associations between PTSD and future-oriented decisions.

Beyond trauma: a review of content and linguistic characteristics of nontrauma narratives in posttraumatic stress disorder.

Background: Using narratives to reflect on experiences, emotions, and thoughts is associated with better health, enhanced mood, and improved symptoms of posttraumatic stress disorder (PTSD). Prior research examining narrative characteristics thought to reflect cognitive styles associated with PTSD has focused on trauma narratives, but the characteristics of nontrauma narratives in relation to PTSD are not fully understood.Objective: We reviewed the PTSD literature examining linguistic characteristics of nontrauma narratives, focusing on affective content, personal pronouns, and cognitive processing words.Method: We searched online databases for both laboratory and social media studies examining these characteristics of nontrauma narratives in relation to PTSD diagnostic status and/or PTSD symptom severity.Results: Following SWiM guidelines [Campbell et al., 2020. Synthesis without meta-analysis (SWiM) in systematic reviews: Reporting guideline. British Medical Journal, 368, l6890], there was moderate evidence for differential use of emotion words in nontrauma narratives in relation to PTSD symptom cluster severity. More severe avoidance/numbing symptoms were associated with greater use of negative emotion words and less use of positive emotion words. Results were mixed for other linguistic elements reviewed.Conclusions: Differential use of emotional language in trauma narratives generalises to nontrauma narratives in individuals with PTSD. Additional research is needed to elucidate the use of personal pronouns and cognitive processing words in nontrauma narratives.

Posttraumatic stress disorder (PTSD) is characterised by negative cognitive styles that not only influence narratives of traumatic events but have the potential to affect the content of narrative generation more broadly.Findings of this synthesised review provided moderate evidence that more severe avoidance/numbing symptoms are related to more negative and fewer positive emotion words in nontrauma narratives.Alterations of narrative content in PTSD extend beyond trauma narratives to nontrauma narratives, which has implications for thinking and communications styles in PTSD.
