Abstract
BACKGROUND The role of nurses in screening for posttraumatic stress disorder is crucial in trauma units. OBJECTIVES To create and evaluate an easy and brief tool for nurses to predict chronic posttraumatic stress disorder 1 year after a motor vehicle crash. METHODS We performed a 1-year follow-up multicenter study from 2007 to 2015, including 274 patients injured in a motor vehicle crash who were hospitalized in an orthopedic trauma unit. Nurses administered the DEPITAC questionnaire. Posttraumatic stress disorder was measured by the Post-Traumatic Stress Disorder Checklist of symptoms during the first year following the crash. A multivariable logistic regression model was implemented to select items significantly associated with posttraumatic stress disorder to improve the DEPITAC questionnaire. Predictive performance to predict posttraumatic stress disorder 1 year after the motor vehicle crash was examined for these different models. RESULTS Of 274 patients studied, a total of 75.9% completed the questionnaire at 1 year of follow-up. We found that only two questions and two simple elements of the patient's medical record (other injury or a person dying during the crash, perception of vital threat, number of children, and length of stay in trauma) predicted posttraumatic stress disorder 1 year after a motor vehicle crash. CONCLUSIONS The brevity of this evaluation, simple scoring rules, and screening test performance suggest that this new screening tool can be easily administered in the acute care setting by nurses.

Abstract
Posttraumatic stress disorder (PTSD) is a chronic and disabling reaction to extreme stress. Because of the strong consequences of long-lasting PTSD symptoms, the research of risk and protective factors is needed. Presented meta-analysis aimed to verify temperament traits according to the Regulative Theory of Temperament as risk/protective factors of PTSD symptoms development. The studies for this meta-analysis were found in four main databases of scientific journals and due to contact with first authors, the unpublished data was accessed as well. The inclusion criteria allowed studies with traumatized adult populations and operationalization of the temperament according to the Regulative Theory of Temperament. Finally, data were included from 19 studies (5971 people: 3443 men and 2528 females, in the age of 13-85) with prospective, longitudinal and cross-sectional study designs, carried out among people exposed to combat trauma, occupational trauma (policemen and fire-fighters), disasters (flood, fire and mining catastrophes), motor vehicle accidents and chronic illnesses. The results show significant moderate and weak relations of all temperament traits to PTSD symptoms regardless of people's gender, type of study, type of trauma, DSM version and temperament measure as well as the time elapsed after the trauma. Among different moderators, a previously unrecognized effect of gender was revealed as it explained a significant amount of variance in the case of emotional reactivity, endurance, and perseveration - the relationship was significantly stronger among men than women. Methodological conclusions for further research on personality and trauma are drawn.

Negative Emotionality Interacts with Trauma Exposure to Prospectively Predict Posttraumatic Stress Disorder Symptoms During Firefighters' First 3 Years of Service. J Trauma Stress 2021; 34:333-344.

Abstract
Firefighters (FFs) protect the public despite significant risks to their health and well-being stemming from frequent trauma exposure and other occupational stressors. A minority of FFs develop posttraumatic stress disorder (PTSD) or related mental health problems, whereas most remain remarkably resilient despite enormous stress. This points toward substantial variability in responses to traumatic stress among FFs. Personality, particularly negative emotionality (NEM), has been shown to predict the development of PTSD in other trauma-exposed populations, yet has not been prospectively studied in relation to PTSD in FFs. The aim of this secondary analysis from a broader study of mental health in FFs was to test whether preemployment NEM predicted PTSD symptom severity over time by influencing how FFs respond to traumatic experiences. In this first prospective study of the development of PTSD symptoms in professional FFs, 322 FFs were recruited from seven urban fire academies across the United States and followed over their first 3 years of fire service. We assessed NEM during the fire academy as well as trauma exposure and both self-reported and clinician-rated PTSD symptoms at 1-, 2-, and 3-year follow-ups. Level of trauma exposure and NEM predicted PTSD symptoms over time, and NEM moderated the effect of trauma exposure on clinician-rated PTSD symptoms across both trauma exposure measures at 1- and 3-year follow-ups, f2 = .03-.10, but not at 2-year follow-up nor for self-reported PTSD symptoms. These findings indicate that NEM, assessed upon entry into a high-risk occupation, is useful in predicting PTSD symptom development.

Abstract
BACKGROUND Avoidance is a well-established maintenance factor in anxiety-related psychopathology. Individuals prone to anxiety show more maladaptive avoidance responses in conditioning paradigms aimed at avoidance learning, which indicates impairments in safety learning. To what extent avoidance learning is associated with posttraumatic stress disorder (PTSD) is still unclear, despite the logical relevance to the symptomatology. In this prospective study, we investigate avoidance learning responses in first responders, a population at high risk for traumatic exposure and thus PTSD development, and studied whether avoidance learning was associated with concurrent and future PTSD symptoms. METHOD Firefighters (N = 502) performed an avoidance learning task at baseline assessment in which they first learned that two conditioned stimuli (CS+) were followed by an aversive stimulus (US) and one conditioned stimulus (CS-) was not. After that, they could learn to which CS avoidance of the US was effective, ineffective or unnecessary. Self-reported PTSD symptoms were assessed at baseline, and at 6, 12, 18 and 24 months. RESULTS Participants exhibited comparable avoidance patterns to low anxiety individuals from previous studies. Avoidance learning responses were not associated with PTSD symptoms at baseline nor at follow-up. DISCUSSION Our study found no evidence that avoidance learning was related to PTSD symptom severity in a high-risk, yet low symptomatic population, nor did it predict the development of PTSD symptoms at a later point in time. Future research should focus on studying avoidance learning in a clinical or high symptomatic sample to further clarify the role of avoidance learning in PTSD development.

Abstract
This study compared the severity of chronic idiopathic urticaria (CIU) and psychiatric symptoms between patients with different levels of posttraumatic stress disorder (PTSD) and investigated a model depicting the interrelationship between PTSD from past trauma, personality traits, coping strategies, CIU severity and psychiatric symptom severity. One hundred CIU and 60 allergy patients participated in the study, completing measures on PTSD, psychiatric symptoms, personality traits and coping strategies. The results showed that for CIU patients, 7%, 40 and 34% met the diagnostic criteria for no-PTSD, partial-PTSD and full-PTSD respectively whereas for allergy patients, 15%, 45 and 18% met the same criteria. Apart from CIU, psychiatric symptom severity differed significantly between diagnostic groups. PTSD was associated with coping strategies which were in turn associated with CIU severity and psychiatric symptom severity. PTSD was not significantly associated with personality. Emotion-focused coping mediated PTSD and CIU severity, PTSD and psychiatric symptom severity and neuroticism and CIU severity. To conclude, psychiatric symptom severity varies depending on the level of PTSD among CIU patients. Neurotic patients with a high level of PTSD from past trauma show raised CIU and psychiatric symptom severity when using emotion-focused coping strategies.

The interaction of BDNF Val66Met, PTSD, and child abuse on psychophysiological reactivity and HPA axis function in a sample of Gulf War Veterans. J Affect Disord 2018; 235:52-60. [PMID: 29649711 PMCID: PMC6354935 DOI: 10.1016/j.jad.2018.04.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 02/28/2018] [Accepted: 04/02/2018] [Indexed: 01/03/2023]
Abstract
INTRODUCTION While the BDNF Val66Met polymorphism has been linked to various psychological disorders, limited focus has been on its relationship to posttraumatic stress disorder (PTSD) and early traumas such as child abuse. Therefore, we assessed whether Val66Met was associated with fear potentiated psychophysiological response and HPA axis dysfunction and whether PTSD status or child abuse history moderated these outcomes in a sample of Veterans. METHODS 226 and 173 participants engaged in a fear potentiated acoustic startle paradigm and a dexamethasone suppression test (DST) respectively. Fear conditions included no, ambiguous, and high threat conditions. Psychophysiological response measures included electromyogram (EMG), skin conductance response (SCR), and heart rate. The Clinician Administered PTSD Scale (CAPS) and the Trauma History Questionnaire (THQ) were used to assess PTSD status and child abuse history respectively. RESULTS Met allele carriers exhibited greater SCR magnitudes in the no and ambiguous threat conditions (p < 0.01 and p < 0.05 respectively). Met carriers with PTSD exhibited greater physiological response magnitudes in the ambiguous (SCR, p < 0.001) and high threat conditions (SCR and heart rate, both p ≤ 0.005). Met carrier survivors of child abuse exhibited blunted heart rate magnitudes in the high threat condition (p < 0.01). Met allele carries with PTSD also exhibited greater percent cortisol suppression (p < 0.005). LIMITATIONS Limitations included small sample size and the cross-sectional nature of the data. CONCLUSIONS The Val66met may impact PTSD susceptibility differentially via enhanced threat sensitivity and HPA axis dysregulation. Child abuse may moderate Val66Met's impact on threat reactivity. Future research should explore how neuronal mechanisms might mediate this risk.

Abstract
This Campbell systematic review examines the effects of deployment on mental health. The review summarizes evidence from 185 studies. All studies used observational data to quantify the effect of deployment. This review includes studies that evaluate the effects of deployment on mental health. A total of 185 studies were identified. However, only 40 of these were assessed to be of sufficient methodological quality to be included in the final analysis. The studies spanned the period from 1993 to 2017 and were mostly carried out in the USA, UK and Australia. The studies all had some important methodological weaknesses. None of the included studies used experimental designs (random assignment). Deployment to military operations negatively affects the mental health functioning of deployed military personnel. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all mental health domains (PTSD, depression, substance abuse/dependence, and common mental disorders), particularly on PTSD. For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive. Plain language summary Deployment to military operations negatively affects the mental health functioning of deployed military personnel: While additional research is needed, the current evidence strongly supports the notion that deployment negatively affects mental health functioning of deployed military personnel.What is this review about?: When military personnel are deployed to military operations abroad they face an increased risk of physical harm, and an increased risk of adverse shocks to their mental health.The primary condition under consideration is deployment to an international military operation. Deployment to a military operation is not a uniform condition; rather, it covers a range of scenarios. Military deployment is defined as performing military service in an operation at a location outside the home country for a limited time period, pursuant to orders.The review included studies that reported outcomes for individuals who had been deployed. This review looked at the effect of deployment on mental health outcomes. The mental health outcomes are: post-traumatic stress disorder (PTSD), major depressive disorder (MDD), common mental disorders (depression, anxiety and somatisation disorders) and substance-related disorders.By identifying the major effects of deployment on mental health and quantifying these effects, the review can inform policy development on deployment and military activity as well as post-deployment support for veterans. In this way the review enables decision-makers to prioritise key areas.What are the main findings of this review?: What studies are included?: This review includes studies that evaluate the effects of deployment on mental health. A total of 185 studies were identified. However, only 40 of these were assessed to be of sufficient methodological quality to be included in the final analysis. The studies spanned the period from 1993 to 2017 and were mostly carried out in the USA, UK and Australia. The studies all had some important methodological weaknesses. None of the included studies used experimental designs (random assignment).Does deployment have an effect on mental health?: Deployment to military operations negatively affects the mental health functioning of deployed military personnel. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all mental health domains (PTSD, depression, substance abuse/dependence, and common mental disorders), particularly on PTSD. For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive.What do the findings of this review mean?: The odds of screening positive for PTSD and depression were consistently high in the longer term. This suggests that efforts should be increased to detect and treat mental disorders, as effects may be long-lasting.Overall the risk of bias in the majority of included studies was high. While it is difficult to imagine a randomised study design to understand how deployment affects mental health, other matters such as changes to personnel policy, or unanticipated shocks to the demand for military personnel, could potentially be a rich source of quasi-experimental variation.How up-to-date is this review?: The review authors searched for studies up to 2017. This Campbell systematic review was published in March 2018. Executive summary BACKGROUND: When military personnel are deployed to military operations abroad they face an increased risk of physical harm, and an increased risk of adverse shocks to their mental health. Research suggests that the increased risk to mental health is mainly due to the hazards of war, combat exposure: firing weapons, road side bombs, seeing fellow soldiers, friends, civilians, and enemies being injured, maimed or killed. These experiences may lead to severe mental stress. The adverse impact on mental health is the psychological cost of war, and it is of interest to policymakers to learn the magnitude of these effects. This review sets out to synthesise available evidence about the consequences of deployment for deployed military personnel in the mental health and social functioning domains.OBJECTIVES: The objective of this review isto synthesise the consequences of deployment to military operation on the mental health and social functioning of deployed military personnel.SEARCH METHODS: We searched electronic databases, grey literature, and references from primary studies and related reviews. No language or date restrictions were applied to the searches. We searched the following electronic databases: Academic Search Elite, Cochrane Library, EMBASE, ERIC, MEDLINE, PsycINFO, Science Citation Index, Social Science Citation Index, SocINDEX, as well as the Nordic platforms: bibliotek.dk, BIBSYS, and LIBRIS. The conclusions of this review are based on the most recent searches performed. The last search was performed in April 2017.SELECTION CRITERIA: Primary studies had to meet the following inclusion criteria: Participants: The participants should be military personnel.Intervention: The condition should be deployment to a military operation.Comparison: The relevant comparisons were either comparing a) deployed military personnel to non-deployed military personnel, b) deployed military personnel to military personnel deployed elsewhere, for example personnel deployed to non-combat operations, c) military personnel deployed to the same operation but stratified by combat exposure.Outcomes: The study should report on one or more mental health outcomes, and/or social functioning for the deployed participants. In particular studies should report on one or more of the following mental health outcomes: PTSD, major depression, substance abuse or dependence (including alcohol), and common mental disorders (depression and anxiety disorders). The following social functioning outcomes were relevant: employment, and homelessness.Study Designs: Both experimental and quasi-experimental designs with a comparison group were eligible for inclusion in the review. Studies were excluded if they: Reported on deployments taking place before 1989.Used a within group pre-post study design.Did not report on at least one of the mental health or social functioning outcomes. DATA COLLECTION AND ANALYSIS: The total number of potentially relevant studies constituted31,049records. A total of 185 studies met the inclusion criteria and were critically appraised by the review authors. The final selection of 185 studies was from 13 different countries.Forty eight of the 185 studies did not report effect estimates or provide data that would allow the calculation of an effect size and standard error. Fifty four studies were excluded because of overlapping samples. The majority of those studies were from USA but the main reason for not using studies from USA in the synthesis was lack of information to calculate an effect size. Nearly half the studies from the UK could not be used in the synthesis due to overlap of data samples. Forty three studies were judged to have a very high risk of bias (5 on the scale) and, in accordance with the protocol, we excluded these from the data synthesis on the basis that they would be more likely to mislead than inform., Thus a total of 40 studies, from five different countries, were included in the data synthesis.Random effects models were used to pool data across the studies. We used the odds ratio. Pooled estimates were weighted with inverse variance methods, and 95% confidence intervals were calculated. The meta-analyses were carried out by time since exposure (short, medium, long, and other time since exposure) and by type of comparison (deployed versus non-deployed, all deployed but stratified by either combat operations versus non-combat operations, or stratified by combat exposure). We performed single factor subgroup analysis. The assessment of any difference between subgroups was based on 95% confidence intervals. Funnel plots were used to assess the possibility of publication bias. Sensitivity analysis was used to evaluate whether the pooled effect sizes were robust across components of methodological quality.MAIN RESULTS: The findings were mixed, depending on the outcome, the time since exposure and the approach (deployed versus non-deployed termed absolute or stratified by extent of combat termed relative) used to investigate the effect. It was not possible to analyse the outcomes homelessness and employment. All studies that could be used in the data synthesis reported on the impact of deployment on mental health; PTSD, depression, substance use or common mental disorder.For assessments taken less than 24 months since exposure the evidence was inconclusive either because too few studies reported results in the short and medium term and/or the degree of heterogeneity between studies was large.For assessments taken at other time points (a variable number of months since exposure) the evidence was inconclusive for the relative comparisons due to either too few studies or a substantial degree of heterogeneity between studies. For the absolute comparison the analysis of common mental disorder was inconclusive, whereas the average effects of PTSD and depression were positive and statistically significant (PTSD odds ratio (OR) was 1.91 (95% confidence interval (CI): 1.28 to 2.85) and OR=1.98 (95% CI: 1.05 to 3.70) for depression). The analysis concerning substance use indicated that deployed participants did not have higher odds of screening positive for substance use compared to non-deployed participants (OR=1.15 (95% CI: 0.98 to 1.36)).For assessments taken more than 24 months post exposure, meta-analyses indicated that the odds of screening positive for PTSD, depression, substance use and common mental disorder were higher for participants in the deployed group compared to participants in the group that were not deployed (PTSD OR=3.31 (95% CI: 2.69 to 4.07), OR=2.19 (95% CI: 1.58 to 3.03) for depression, OR=1.27 (95% CI: 1.15 to 1.39) for substance use, and OR=1.64 (95% CI: 1.38 to 1.96) for common mental disorder). Likewise, participants reporting high combat exposure had higher odds of screening positive for PTSD and depression than participants reporting lower exposure for long term assessments (PTSD OR=3.05 (95% CI: 1.94 to 4.80) and OR=1.81 (95% CI: 1.28 to 2.56) for depression). The analyses of substance use and common mental disorder were inconclusive due to too few studies.On the basis of the prevalence of mental health problems in pre-deployed or non-deployed population based comparison sampleswe would therefore expect the long term prevalence of PTSD in post-deployed samples to be in the range 6.1 - 14.9%, the long term prevalence of depression to be in the range from 7.6% to 18%, the long term prevalence of substance use to be in the range from 2.4% to 17.5% and the prevalence of common mental disorder to be in the range from 10% to 23%.Sensitivity analyses resulted in no appreciable change in effect size, suggesting that the results are robust.It was only possible to assess the impact of two types of personnel characteristics (branch of service and duty/enlistment status) on the mental health outcomes. We found no evidence to suggest that the effect of deployment on any outcomes differ between these two types of personnel characteristics.AUTHORS' CONCLUSIONS: Deployment to military operations negatively affects the mental health functioning of deployed military personnel. We focused on the effect of deployment on PTSD (post-traumatic stress disorder), depression, substance abuse/dependence, and common mental disorders (depression and anxiety disorders). For assessments taken less than 24 months (or a variable number of months since exposure) the evidence was less consistent and in many instances inconclusive. For assessments taken more than 24 months since exposure, we consistently found adverse effects of deployment on all domains, particularly on PTSD. There is increased political awareness of the need to address post deployment mental health problems. The odds of screening positive for PTSD and depression were consistently high in the longer term. This suggests that efforts should be increased to detect and treat mental disorders, as effects may be long lasting. Mental illness is of particular concern in the military for operational reasons, but they may be hard to detect in the military setting because a military career is intimately linked with mental and physical strength.It was not possible to examine a number of factors which we had reason to expect would impact on the magnitude of the effect. This would have been particularly relevant from a policy perspective because these are direct parameters that one could use to optimally "organize" deployment in order to minimize impacts on mental health functioning.While additional research is needed, the current evidence strongly supports the notion that deployment negatively affects mental health functioning of deployed military personnel. The next step is to begin to examine preventive measures and policies for organizing deployment, in order to minimize the effects on mental health.

Abstract
OBJECTIVES This study revisited the prevalence of posttraumatic stress disorder (PTSD) and examined a hypothesized model describing the interrelationship between trauma exposure characteristics, trauma centrality, emotional suppression, PTSD, and psychiatric comorbidity among Syrian refugees. METHODS A total of 564 Syrian refugees participated in the study and completed the Harvard Trauma Questionnaire, General Health Questionnaire (GHQ-28), Centrality of Event Scale, and Courtauld Emotional Control Scale. RESULTS Of the participants, 30% met the cutoff for PTSD. Trauma exposure characteristics (experiencing or witnessing horror and murder, kidnapping or disappearance of family members or friends) were associated with trauma centrality, which was associated with emotional suppression. Emotional suppression was associated with PTSD and psychiatric comorbid symptom severities. Suppression mediated the path between trauma centrality and distress outcomes. CONCLUSIONS Almost one-third of refugees can develop PTSD and other psychiatric problems following exposure to traumatic events during war. A traumatized identity can develop, of which life-threatening experiences is a dominant feature, leading to suppression of depression with associated psychological distress.

Objective: This study investigated whether pre-deployment dissociation was associated with previously identified post-traumatic stress disorder (PTSD) symptom trajectories from before to 2.5 years after military deployment. Furthermore, it examined whether the tendency to dissociate, pre-deployment personality factors, conceptualized by the Big Five model, and previous trauma represented independent risk factors for post-deployment PTSD symptoms. Method: This prospective study included the entire team of 743 soldiers from the Danish Contingent of the International Security Assistance Force 7 deployed to Afghanistan in 2009. Data consisted of self-report measures and were collected six times: before deployment; during deployment; and 1-3 weeks, 2 months, 7 months and 2.5 years after homecoming. Results: The findings indicate significant associations between pre-deployment dissociation and six PTSD trajectories (p < 0.001, η2 = 0.120). Based on mean differences in dissociation for the six trajectories, two main groups emerged: a group with high dissociation scores at pre-deployment, which had moderate PTSD symptom levels at pre-deployment and fluctuated over time; and a group with low dissociation scores at pre-deployment, which had low initial PTSD symptom levels and diverged over time. Our study also confirmed previous findings of a positive association between neuroticism and dissociation (r = 0.31, p < 0.001). This suggests that negative emotionality may be a vulnerability that enhances dissociative experiences, although a causal link cannot be concluded from the findings. Finally, pre-deployment dissociation, pre-deployment neuroticism and a history of traumatic events, as independent factors, were significant predictors of post-deployment PTSD (p < 0.001, R2 = 0.158). Conclusions: The study emphasizes the multiplicity of factors involved in the development of PTSD, and group differences in dissociative symptoms support the heterogeneity in PTSD. Further, this study points to specific aspects of personality that may be targeted in a clinical setting and in pre-deployment assessments in the military.

Abstract
BACKGROUND Intolerance of uncertainty (IU) has been associated with post-traumatic stress symptoms (PTSS) in the literature. However, no research to date has investigated the relationship between IU and PTSS within a clinical trauma-exposed sample, which is an important next step in the literature and crucial for the generalizability of these findings. Therefore, the current study hypothesized that IU would be related to increased PTSS within a clinical sample of trauma-exposed individuals. Further, we hypothesized that IU would be related to elevated PTSS after accounting for anxiety sensitivity (AS) and negative affect (NA), two known correlates of PTSS. Finally, we examined the relations between IU and the PTSS clusters (i.e., avoidance, emotional numbing, hyperarousal, and re-experiencing) while covarying for AS and NA. METHODS Participants included community adults (n=126) presenting at an outpatient clinic. All participants had previously experienced a traumatic event as defined by the DSM-5 PTSD Criterion A. METHODS Results revealed that IU was significantly associated with increased PTSS above and beyond AS and NA. Further, results indicated that IU was significantly related to the avoidance, hyperarousal, and emotional numbing PTSS clusters, even after covarying for AS and NA. IU was not significantly associated with the PTSS re-experiencing cluster once AS and NA were taken into account. CONCLUSIONS Our results expand upon the extant literature by demonstrating that IU is associated with PTSS above and beyond AS and NA within a clinical trauma-exposed sample. These findings are discussed in terms of promising directions for future research and treatment strategies.

Abstract
BACKGROUND It is unclear which potentially modifiable risk factors best predict post-trauma psychiatric disorders. We aimed to identify pre-trauma risk factors for post-traumatic stress disorder (PTSD) or major depression (MD) that could be targeted with resilience interventions. METHOD Newly recruited paramedics (n = 453) were assessed for history of mental disorders with structured clinical interviews within the first week of their paramedic training and completed self-report measures to assess hypothesized predictors. Participants were assessed every 4 months for 2 years to identify any episodes of PTSD and MD; 386 paramedics (85.2%) participated in the follow-up interviews. RESULTS In all, 32 participants (8.3%) developed an episode of PTSD and 41 (10.6%) an episode of MD during follow-up. In all but nine cases (2.3%), episodes had remitted by the next assessment 4 months later. At 2 years, those with episodes of PTSD or MD during follow-up reported more days off work, poorer sleep, poorer quality of life, greater burn-out; and greater weight-gain for those with PTSD. In line with theories of PTSD and depression, analyses controlling for psychiatric and trauma history identified several pre-trauma predictors (cognitive styles, coping styles and psychological traits). Logistic regressions showed that rumination about memories of stressful events at the start of training uniquely predicted an episode of PTSD. Perceived resilience uniquely predicted an episode of MD. CONCLUSIONS Participants at risk of developing episodes of PTSD or depression could be identified within the first week of paramedic training. Cognitive predictors of episodes of PTSD and MD are promising targets for resilience interventions.

Abstract
BACKGROUND Working with victims and perpetrators of child sexual abuse has been shown to cause secondary traumatic stress (STS) in child protection professionals. AIMS To examine the role of gender and personality on the development of secondary trauma responses. METHODS A study of Internet child abuse investigators (ICAIs) from two UK police forces. Participants completed a personality test together with tests for anxiety, depression, burnout, STS and post-traumatic stress disorder to assess secondary trauma. The data were normally distributed and the results were analysed using an independent t-test, Pearson correlation and linear regression. RESULTS Among 126 study subjects (50 females and 75 males), there was a higher incidence of STS in investigators who were female, introverted and neurotic. However, there were lower levels of STS in the participants in this study than those found in other studies. CONCLUSIONS Psychological screening and surveillance of ICAI teams can help to identify risk factors for the development of STS and identify where additional support may be required.

Abstract
OBJECTIVES Symptoms of post-traumatic distress in mothers of preterm infants have been a subject of mental health research. The aim of this study was to assess the prevalence of and risk factors associated with such symptoms in mothers of preterm infants in Taiwan. METHODS This was a cross-sectional study performed between January 1, 2010 and June 30, 2011. One hundred and two mothers of preterm infants born at less than 37 weeks gestation and with a subsequent neonatal intensive care unit (NICU) stay between 2005 and 2009 were recruited. Participants completed a demographic questionnaire, the Impact of Event Scale-Revised (IES-R), the Center for Epidemiologic Studies Depression Scale (CES-D) and the neuroticism subscale of the Maudsley Personality Inventory (MPI). The preterm infants' data were taken from medical records. RESULTS The prevalence of symptoms of distress was 25.5% (26/102) in the participants. These symptoms were associated with previous miscarriages, preterm premature rupture of membranes, neurotic personality and depression. CONCLUSIONS The experience of preterm birth and NICU hospitalization can be traumatic to mothers. Early support for mothers during the preterm infants' NICU stay and transition to home care are recommended.

Abstract
BACKGROUND Consequences of war-related traumatisation have mostly been investigated in military and predominant male populations, while research on female civilian victims of war has been neglected. Furthermore, research of post-war posttraumatic stress disorder (PTSD) in women has rarely included early-life trauma in their prediction models, so the contribution of trauma in childhood and early youth is still unexplored. OBJECTIVE To examine the relationship of early-life trauma, war-related trauma, personality traits, and symptoms of posttraumatic stress among female civilian victims of the recent war in Croatia. METHOD The cross-sectional study included 394 participants, 293 war-traumatised adult women civilians, and 101 women without war-related trauma. Participants were recruited using the snowball sampling method. The applied instruments included the Clinician-Administrated PTSD Scale (CAPS), the NEO Personality Inventory-Revised (NEO-PI-R), the War Stressors Assessment Questionnaire (WSAQ), and the Early Trauma Inventory Self Report-Short Form (ETISR-SF). A hierarchical multiple regression analysis was performed to assess the prediction model of PTSD symptom severity measured by CAPS score for current PTSD. RESULTS The prevalence of current PTSD (CAPS cut-off score=65) in this cohort was 20.7%. The regression model that included age, early-life trauma, war-related trauma, neuroticism, and extraversion as statistically significant predictors explained 45.8% of variance in PTSD symptoms. CONCLUSIONS Older age, exposure to early-life trauma, exposure to war-related traumatic events, high neuroticism, and low extraversion are independent factors associated with higher level of PTSD symptoms among women civilian victims of war.

Abstract
Studies that include multiple assessments of a particular instrument within the same population are based on the presumption that this instrument measures the same construct over time. But what if the meaning of the construct changes over time due to one's experiences? For example, the experience of a traumatic event can influence one's view of the world, others, and self, and may disrupt the stability of a questionnaire measuring posttraumatic stress symptoms (i.e., it may affect the interpretation of items). Nevertheless, assessments before and after such a traumatic event are crucial to study longitudinal development of posttraumatic stress symptoms. In this study, we examined measurement invariance of posttraumatic stress symptoms in a sample of Dutch soldiers before and after they went on deployment to Afghanistan (N = 249). Results showed that the underlying measurement model before deployment was different from the measurement model after deployment due to invariant item thresholds. These results were replicated in a sample of soldiers deployed to Iraq (N = 305). Since the lack of measurement invariance was due to instability of the majority of the items, it seems reasonable to conclude that the underlying construct of PSS is unstable over time if war-zone related traumatic events occur in between measurements. From a statistical point of view, the scores over time cannot be compared when there is a lack of measurement invariance. The main message of this paper is that researchers working with posttraumatic stress questionnaires in longitudinal studies should not take measurement invariance for granted, but should use pre- and post-symptom scores as different constructs for each time point in the analysis.

Abstract
We investigated autobiographical memory in a group of passengers onboard a trans-Atlantic flight that nearly ditched at sea. The consistency of traumatic exposure across passengers, some of whom developed post-traumatic stress disorder (PTSD), provided a unique opportunity to assess verified memory for life-threatening trauma. Using the Autobiographical Interview, which separates episodic from non-episodic details, passengers and healthy controls (HCs) recalled three events: the airline disaster (or a highly negative event for HCs), the September 11, 2001 attacks, and a non-emotional event. All passengers showed robust mnemonic enhancement for episodic details of the airline disaster. Although neither richness nor accuracy of traumatic recollection was related to PTSD, production of non-episodic details for traumatic and non-traumatic events was elevated in PTSD passengers. These findings indicate a robust mnemonic enhancement for trauma that is not specific to PTSD. Rather, PTSD is associated with altered cognitive control operations that affect autobiographical memory in general.

Abstract
Although memories of traumatic events are often remembered vividly, these memories are subject to change over time. In our previous study, we found that Dutch infantry veterans who had served in Iraq often reported stressful events at a second assessment point that they had not reported during a prior assessment point and vice versa. In the present exploratory study, we recontacted subjects from this previous study and asked how they explained the discrepancy in their memory reports between post-deployment assessment points 1 and 2. Common explanations were: interpreting the item differently, having forgotten the incident initially, repression and having accidentally incorporated someone else's experience into their own memory. Although such reports are not necessarily revelatory of the mechanisms driving discrepancies in memory reports over time, our study illuminates the metacognitive variables involved.

Abstract
Many studies have shown that individuals with posttraumatic stress disorder (PTSD) experience more anger over time and across situations (i.e., trait anger) than trauma-exposed individuals without PTSD. There is a lack of prospective research, however, that considers anger levels before trauma exposure. The aim of this study was to prospectively assess the relationship between trait anger and PTSD symptoms, with several known risk factors, including baseline symptoms, neuroticism, and stressor severity in the model. Participants were 249 Dutch soldiers tested approximately 2 months before and approximately 2 months and 9 months after their deployment to Afghanistan. Trait anger and PTSD symptom severity were measured at all assessments. Structural equation modeling including cross-lagged effects showed that higher trait anger before deployment predicted higher PTSD symptoms 2 months after deployment (β = .36), with stressor severity and baseline symptoms in the model, but not with neuroticism in the model. Trait anger at 2 months postdeployment did not predict PTSD symptom severity at 9 months, and PTSD symptom severity 2 months postdeployment did not predict subsequent trait anger scores. Findings suggest that trait anger may be a pretrauma vulnerability factor for PTSD symptoms, but does not add variance beyond the effect of neuroticism.

Abstract
BACKGROUND Most previous research that has examined mental health among Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) combatants has relied on self-report measures to assess mental health outcomes; few studies have examined predictors of actual mental health diagnoses. The objective of this longitudinal investigation was to identify predictors of psychiatric disorders among Marines who deployed to combat in Iraq and Afghanistan. METHODS The study sample consisted of 1113 Marines who had deployed to Iraq or Afghanistan. Demographic and psychosocial predictor variables from a survey that all Marines in the sample had completed were studied in relation to subsequent psychiatric diagnoses. Univariate and multivariate logistic regression were used to determine the influence of the predictors on the occurrence of psychiatric disorders. RESULTS In a sample of Marines with no previous psychiatric disorder diagnoses, 18% were diagnosed with a new-onset psychiatric disorder. Adjusting for other variables, the strongest predictors of overall psychiatric disorders were female gender, mild traumatic brain injury symptoms, and satisfaction with leadership. Service members who expressed greater satisfaction with leadership were about half as likely to develop a mental disorder as those who were not satisfied. Unique predictors of specific types of mental disorders were also identified. CONCLUSIONS Overall, the study's most relevant result was that two potentially modifiable factors, low satisfaction with leadership and low organizational commitment, predicted mental disorder diagnoses in a military sample. Additional research should aim to clarify the nature and impact of these factors on combatant mental health.

Abstract
OBJECTIVE To test the effect of misinformation outside of the laboratory and to explore correlates of the effect, including arousal, cognitive ability, and neuroticism. METHOD About 2 months before deployment to Afghanistan, 249 soldiers enrolled in this study, which was embedded in a larger project. Two months after deployment, participants were interviewed about stressors on deployment and they received subtle misinformation about a fictional event on deployment. Seven months later, they were retested, and completed a questionnaire about events on deployment. RESULTS At 9 months, a total of 26% of participants reported that they had experienced the fictional event, although 7 months earlier they said they had not experienced it. Logistic regression analyses revealed that lower cognitive ability and a combination of high arousal and more stressors on deployment were related to higher susceptibility to the misinformation effect. CONCLUSIONS Results suggest that information provided by another source may be incorporated into related autobiographical memory, particularly for individuals with lower cognitive ability, high arousal at the time of encoding the information and more related experiences.

Abstract
Although the effects of combat deployment on posttraumatic stress disorder have been extensively studied, little is known about the effects of combat deployment on depression and anxiety. This study examined the factors associated with anxiety and depression in a sample of 1560 US Marines who were deployed to Iraq and Afghanistan. Eleven demographic and psychosocial factors were studied in relation to depression and anxiety. Five factors emerged as significant in relation to depression: deployment-related stressors, combat exposure, attitudes toward leadership, mild traumatic brain injury symptoms, and marital status. The same factors, with the exception of marital status, emerged as significant in relation to anxiety. Deployment-related stressors had a stronger association with both depression and anxiety than any other variable, including combat exposure. This finding is important because deployment-related stressors are potentially modifiable by the military.

Abstract
In this study, the authors compared the respective contribution of an individual's subjective response and the frequency of exposure to critical incidents to the development of symptoms of posttraumatic stress disorder (PTSD) in a sample of 136 nurses and ambulance personnel working in military facilities. They found no relationship between the frequency of encountered critical incidents and the occurrence of PTSD symptoms. The subjective response to a stressor contributed to the development of PTSD symptoms and was most strongly associated with intrusion, partial eta squared =.23, and hyperarousal symptoms, partial eta squared =.16. Stressors that elicited the most intense affects within this population were those involving children and those where workers encountered limitations in supplies and resources.

Abstract
This study examined the relationship between the emotion-regulating factor alexithymia and the occurrence of posttraumatic stress disorder (PTSD) after critical incidents in a nonclinical sample of 136 nurses and ambulance personnel working in military facilities. The results showed that alexythima accounts for variance in PTSD symptoms. Breaking PTSD into its 4 symptom clusters, alexithymia was found to predict numbing and hyperarousal symptoms but not avoidance or reexperiencing symptoms. Finally, the rarely investigated, but clinically relevant, distinctive subdimensions of alexithymia were examined in relation to the 4 PTSD clusters. The difficulty identifying feelings subscale contributed most to the numbing and hyperarousal PTSD subscales. Clinical implications and future research directions are discussed.

Abstract
Although the DSM-IV recognizes that events can traumatize by evoking horror, not just fear, the role of disgust in the development of posttraumatic stress disorder (PTSD) has received little research attention. In a study of soldiers deployed to Afghanistan, we examined whether reports of peritraumatic disgust and trait disgust vulnerability factors (disgust propensity and disgust sensitivity) predict PTSD-symptoms, independently of peritraumatic fear, neuroticism, and anxiety sensitivity. Participants (N = 174) enrolled in this study before deployment, and were retested around 6 months (N = 138; 79%) and, again, 15 months (N = 107; 62%) after returning home. The results showed that (1) greater peritraumatic disgust and fear independently predicted PTSD-symptom severity at 6 months, (2) greater disgust propensity predicted more peritraumatic disgust, but not PTSD-symptom severity, and (3) disgust sensitivity moderated the relationship between peritraumatic disgust and PTSD-symptom severity. Implications of these findings for broadening the affective vulnerabilities that may contribute to PTSD will be discussed.

Abstract
The objective of this study was to identify factors associated with antisocial behavior in 1,543 Marines who deployed to combat zones in support of conflicts in Iraq and Afghanistan during 2002-2007. Five factors were associated with antisocial behavior in multivariate analyses: post-traumatic stress disorder (PTSD) symptoms, deployment-related stressors, combat exposure, younger age, and being divorced. PTSD symptoms had a stronger association with antisocial behavior than any other variable. A unique and important finding of this study was the association between deployment-related stressors and a higher incidence of antisocial behavior. Because deployment-related stressors are potentially modifiable, the military may be able to address them in concrete ways such as by shortening deployments and improving communication with home.

Abstract
OBJECTIVES The purpose of this study is to explore the association of neuroticism with the metabolic syndrome, separate components of the metabolic syndrome, and the number of components of metabolic syndrome an individual possesses. The purpose of this study is to examine also the extent to which any associations are accounted for by sociodemographic factors, health behaviors, and cognitive ability. METHOD Participants were 4208 men drawn from the Vietnam Experience Study. From military archives, and a later telephone interview and psychological and medical examination, sociodemographic, health behavior, cognitive ability, neuroticism, and health data were collected. Neuroticism and cognitive ability were assessed with standardized tests during the medical examination. Presence of the metabolic syndrome was based on body mass index, fasting blood glucose or a diagnosis of diabetes, high blood pressure or taking antihypertensive medication, high-density lipoprotein cholesterol, and triglyceride levels. RESULTS Neuroticism was positively associated with the occurrence of the metabolic syndrome and several of its components in both age-, and sociodemographic- and health behavior-adjusted analyses. Many associations were accounted for by individual difference in cognitive ability. Neuroticism was robustly associated with the number of components of the metabolic syndrome after adjustment. CONCLUSIONS Individuals with higher neuroticism scores had a higher prevalence of the metabolic syndrome and a larger number of its components. On the whole, differences in cognitive ability appeared to partially mediate the relationship between neuroticism and the metabolic syndrome.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) has been called one of the signature injuries of the Iraq War. In this review prevalence estimates of PTSD are summarized and discrepancies are discussed in relation to methodological differences between studies. METHOD We searched for population-based studies with a minimum sample size of 300. Studies based on help-seeking samples were excluded. We identified 60 possible papers, of which 19 fulfilled the inclusion criteria. Prevalence estimates and study characteristics were examined graphically with forest plots, but because of high levels of heterogeneity between studies, overall estimates of PTSD prevalence were not discussed. RESULTS The prevalence of PTSD in personnel deployed to Iraq varied between 1.4% and 31%. Stratifying studies by PTSD measure only slightly reduced the variability in prevalence. Anonymous surveys of line infantry units reported higher levels of PTSD compared to studies that are representative of the entire deployed population. UK studies tend to report lower prevalence of PTSD compared with many US studies; however, when comparisons are restricted to studies with random samples, prevalences are similar. US studies that have assessed personnel more than once since return from deployment have shown that PTSD prevalence increases over the 12 months following deployment. CONCLUSIONS Differences in methodologies and samples used should be considered when making comparisons of PTSD prevalence between studies. Further studies based on longitudinal samples are needed to understand how the prevalence of PTSD changes over time.

Abstract
The effect of combat and operational stress on the mental health of military personnel is a major concern. The objective of this study was to identify factors associated with possible posttraumatic stress disorder (PTSD). A questionnaire was completed by 1,569 Marines who deployed in support of conflicts in Iraq and Afghanistan (2002-2007). Using the PTSD Checklist with a cutoff score of 44, 17.1% of the sample screened positive for possible PTSD. Of 9 demographic and psychosocial factors examined in relation to PTSD, 4 were significant in a multivariate analysis: deployment-related stressors, combat exposure, marital status, and education. Deployment-related stressors had a stronger association with PTSD than any other variable. This is an important finding because deployment-related stressors are potentially modifiable.

Abstract
BACKGROUND The extant major psychiatric classifications DSM-IV, and ICD-10, are atheoretical and largely descriptive. Although this achieves good reliability, the validity of a medical diagnosis would be greatly enhanced by an understanding of risk factors and clinical manifestations. In an effort to group mental disorders on the basis of aetiology, five clusters have been proposed. This paper considers the validity of the fourth cluster, emotional disorders, within that proposal. METHOD We reviewed the literature in relation to 11 validating criteria proposed by a Study Group of the DSM-V Task Force, as applied to the cluster of emotional disorders. RESULTS An emotional cluster of disorders identified using the 11 validators is feasible. Negative affectivity is the defining feature of the emotional cluster. Although there are differences between disorders in the remaining validating criteria, there are similarities that support the feasibility of an emotional cluster. Strong intra-cluster co-morbidity may reflect the action of common risk factors and also shared higher-order symptom dimensions in these emotional disorders. CONCLUSION Emotional disorders meet many of the salient criteria proposed by the Study Group of the DSM-V Task Force to suggest a classification cluster.

Abstract
This study investigates the influence of local and international news events on utilization of health services resources and health complaints as presented by victims of a fireworks depot disaster. It was hypothesized that victims (N = 2,854) will show more utilization and health complaints to their general practitioner (GP) in the week after 11 local news reports of events relating to the specific index trauma and 6 unrelated disasters reported in international print news, than the week before. Health data of victims and matched controls were extracted from electronic medical records, covering 4-years postdisaster. Especially local news events concerning the cause of the disaster were associated in both victims and controls with an increase of GP utilization and health complaints, including medically unexplained physical symptoms, chronic diseases, and psychological problems. No difference between victims and controls were found.

Abstract
A better understanding of factors influencing human responses to acute stress is needed to enhance prevention and treatment of stress-related disorders. In the current study, the authors examined predictors of acute stress symptoms during intense military training in 35 men. In univariate and multivariate models, perceived stress, passive coping, and emotion-focused coping during daily living predicted acute stress symptoms in response to realistic survival training, whereas active coping and problem-focused coping did not. Baseline stress levels and coping styles, both of which may be modifiable, appear to play a fundamental role in the human response to acute uncontrollable stress. Additional research is needed to better elucidate the relative and interactive contributions of behavioral predictors of acute stress.

Abstract
OBJECTIVE The aim is to consider whether the courts and experts in their application of Criterion F for posttraumatic stress disorder (PTSD) have applied it consistently in civil claims brought years after the event. METHOD Three cases for compensation relating to the Voyager disaster are considered. RESULTS It appears, from the cases considered in this paper, that while courts consider that Criterion F is crucial in making a diagnosis of PTSD, there are some inconsistencies in terms of understanding and applying this criterion, both by the courts and experts. This may be because of a lack of guidance in psychiatric texts as to how to apply Criterion F. CONCLUSIONS Criterion F is, after the satisfaction of Criterion A(1), arguably the most important of the criteria for PTSD for, while the symptoms referred to in Criteria B-D have been shown to be fairly easy to simulate, it is arguably harder to do this with Criterion F, particularly in cases that arise a long time after the event. It is important therefore that psychiatrists assessing persons so long after an event adhere rigorously to Criterion F, because it is based on facts open to objective corroboration, while criteria B, C and D tend to rely on subjective experiences which are the most sensitive to distortion. Thus, it is to be hoped that if DSM-V is to maintain a criterion of clinically significant distress or impairment in the majority of the disorders described therein, it will provide some assistance as to how this criteria should be applied.

Abstract
Retrospective accounts of traumatic events are consistently associated with symptoms of post-traumatic stress disorder (PTSD). This has often been interpreted as causal impact of such events on psychological functioning, but recent studies suggest that the causal direction is (partly) reversed: high levels of PTSD symptoms may be associated with amplified recollections of precipitating traumatic events. The aim of this prospective study was to index the consistency with which Dutch Army soldiers reported traumatic stressors and nontraumatic stressors on their deployment to Iraq, and to examine to what extent PTSD symptoms and pre-existing reporting biases, such as that arising from neuroticism, affect memory inconsistency. Retrospective accounts of stressors were highly variable over time. Individuals with higher levels of PTSD symptoms and neuroticism, lower levels of extraversion, and fewer prior missions, were more prone to increased reporting over time.
