Abstract
BACKGROUND Despite extensive research, symptom structure of posttraumatic stress disorder (PTSD) is highly debated. The network approach to psychopathology offers a novel method for understanding and conceptualizing PTSD. However, extant studies have mainly used small samples and self-report measures among sub-clinical populations, while also overlooking co-morbid depressive symptoms. METHODS PTSD symptom network topology was estimated in a sample of 1489 treatment-seeking veteran patients based on a clinician-rated PTSD measure. Next, clinician-rated depressive symptoms were incorporated into the network to assess their influence on PTSD network structure. The PTSD-symptom network was then contrasted with the network of 306 trauma-exposed (TE) treatment-seeking patients not meeting full criteria for PTSD to assess corresponding network differences. Finally, a directed acyclic graph (DAG) was computed to estimate potential directionality among symptoms, including depressive symptoms and daily functioning. RESULTS The PTSD symptom network evidenced robust reliability. Flashbacks and getting emotionally upset by trauma reminders emerged as the most central nodes in the PTSD network, regardless of the inclusion of depressive symptoms. Distinct clustering emerged for PTSD and depressive symptoms within the comorbidity network. DAG analysis suggested a key triggering role for re-experiencing symptoms. Network topology in the PTSD sample was significantly distinct from that of the TE sample. CONCLUSIONS Flashbacks and psychological reactions to trauma reminders, along with their strong connections to other re-experiencing symptoms, have a pivotal role in the clinical presentation of combat-related PTSD among veterans. Depressive and posttraumatic symptoms constitute two separate diagnostic entities, but with meaningful between-disorder connections, suggesting two mutually-influential systems.

Abstract
AbstractBackgroundThe goal of this study is to assess prevalence and incidence of psychiatric sequelae in a sample of inpatient accident survivors. Such an attempt to assess psychiatric conditions that originate due to an accident seems to be important; this does not include psychiatric conditions already present prior to the accident.Method208 accident victims were consecutively examined over a period of 12 months using DSM-IV diagnostic assessment, CAPS, and self-evaluating questionnaires as well as ISS for injury severity. A predictor model for psychiatric disorders was set up.ResultsIncidence of newly developed Axis I disorders in our sample was 14.2% (6 months) and 12.3% (12 months). Incidence of PTSD was 5.9% (6 months) and 2.5% (12 months). Comorbidity was a general phenomenon. The psychiatric condition prior to the accident could be identified as a predictor for the development of Axis I disorders. The subjectively evaluated intensity of experienced threat to life and female gender were the main predictors for the development of PTSD.ConclusionsAccidents can lead to different psychiatric disorders. PTSD as a single diagnosis is rare. Without taking into account pre-existing disorders, the incidence may be overestimated. Two predictor models for the development of PTSD and other mental disorders are presented.

Abstract
INTRODUCTION We explored the predictors of co-occurring depressive disorder (DD) in individuals with posttraumatic stress disorder (PTSD) in an outpatient psychiatric setting. METHODS Participants (N = 170; mean age = 40.78, SD = 16.15 years; 58.8% women) included 71 adult patients who met the criteria for a PTSD diagnosis and 99 adult patients who met the criteria for a comorbid PTSD/DD diagnosis. Potential predictors included trauma types (focusing on trauma characteristics), history of previous traumatic experiences (i.e., the number of lifetime traumatic events before current trauma and childhood maltreatment), and post-trauma variables (i.e., elapsed time since the current traumatic event and the severity of PTSD symptoms). RESULTS A logistic regression analysis-including demographic variables, trauma types, history of previous traumatic experiences, and post-trauma variables that showed significant differences between the two groups-was conducted. The effects of repeated trauma (OR = 13.18, 95% CI [3.44, 50.48], p < .001), the number of lifetime traumatic events (OR = 1.04, 95% CI [1.01, 1.51], p = .044), and childhood maltreatment (OR = 1.23, 95% CI [1.01, 1.51], p = .004) were associated with a greater likelihood of concurrent PTSD/DD. CONCLUSION Cumulative characteristics such as maltreatment and the number of lifetime traumatic events before the current trauma as well as repetitive properties of the most recent trauma present a key risk factor for co-occurring PTSD/DD.

Abstract
BACKGROUND Individuals with comorbid posttraumatic stress disorder and major depressive disorder (PTSD-MDD) often exhibit greater functional impairment and poorer treatment response than individuals with PTSD alone. Research has not determined whether PTSD-MDD is associated with different network connectivity abnormalities than PTSD alone. METHODS We used functional magnetic resonance imaging (fMRI) to measure resting state functional connectivity (rs-FC) patterns of brain regions involved in fear and reward processing in three groups: patients with PTSD-alone (n = 27), PTSD-MDD (n = 21), and trauma-exposed healthy controls (TEHCs, n = 34). Based on previous research, seeds included basolateral amygdala (BLA), centromedial amygdala (CMA), and nucleus accumbens (NAcc). RESULTS Regardless of MDD comorbidity, PTSD was associated with decreased connectivity of BLA-orbitalfrontal cortex (OFC) and CMA-thalamus pathways, key to fear processing, and fear expression, respectively. PTSD-MDD, compared to PTSD-alone and TEHC, was associated with decreased connectivity across multiple amygdala and striatal-subcortical pathways: BLA-OFC, NAcc-thalamus, and NAcc-hippocampus. Further, while both the BLA-OFC and the NAcc-thalamus pathways were correlated with MDD symptoms, PTSD symptoms correlated with the amygdala pathways (BLA-OFC; CMA-thalamus) only. CONCLUSIONS Comorbid PTSD-MDD may be associated with multifaceted functional connectivity alterations in both fear and reward systems. Clinical implications are discussed.

Abstract
INTRODUCTION There have been deaths and injuries after an explosion which happened in an industrial region in Ankara in February 2011. The aim of this study was to determine the prevalence of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD), and to determine the variables which can be the risk factors for PTSD. METHODS In this study, we included a total of 197 subjects who were present at the factory building and at the four offices nearby when the disaster occurred. All the participants were assessed one month after the explosion and 157 of them were reassessed six months after the explosion. Socio-demographic information forms were given and the Clinician-Administered PTSD Scale (CAPS) was administered to the participants one month after the explosion. Psychiatric assessments were done using the structured clinical interview for DSM-IV axis-I disorders (SCID-I). The CAPS was re-applied six month after the disaster. RESULTS At the first-month assessments, ASD was detected in 37.1% of participants and PTSD in 13.7%, whereas PTSD was observed in 16.6% of subjects at the sixth month of the accident. According to the first month data, having any psychiatric disorder before the incident, physical injury, acquaintances among the dead and the injured people, being involved in the incident and seeing dead people were detected as the risk factors for PTSD. At the sixth month assessment, physical injury, acquaintances among the dead and the injured, being involved in the incident were seen as risk factors for PTSD. CONCLUSION ASD and PTSD can be seen after an explosion. Having a previous psychiatric disorder and being directly affected by trauma and being injured are the risk factors for PTSD. This study implies that preventive mental health care services should include the management of current psychiatric condition and employee safety issues.

Abstract
Posttraumatic Stress Disorder (PTSD) and Major Depressive Disorder (MDD) are two highly comorbid and debilitating disorders experienced by more than half of intimate partner violence victims (IPV). Hypothalamic-pituitary-adrenal (HPA) abnormalities are common in both disorders, though the direction of abnormalities often differs. The present study examined the relationship between comorbid PTSD and MDD, and the (salivary) cortisol waking response in 104 recently abused IPV victims. Waking cortisol levels, area under the waking curve with respect to ground (AUCg), and AUC with respect to increase (AUCi) were examined to determine the relation of HPA dynamics to comorbidity for basal versus more dynamic measures. Prior to accounting for comorbidity, women with PTSD or MDD showed significantly greater AUCi than women without the respective disorder. Accounting for comorbidity, PTSD only did not differ from other groups, while MDD only and PTSD + MDD showed greater AUCi than women with neither disorder. Results were nonsignificant for waking cortisol levels or AUCg. Results suggest that MDD drives elevated waking cortisol response, but not basal cortisol activity in recently abused IPV victims. Results demonstrate the importance of examining comorbid diagnoses and HPA activity from a dynamic perspective. Therapeutic implications are discussed.

Abstract
Post-traumatic stress disorder (PTSD) is a common and chronic anxiety disorder that can result after exposure to a traumatic event. Though our understanding of the aetiology of PTSD is incomplete, several neurobiological systems have been implicated in the pathophysiology and vulnerability towards developing PTSD after trauma exposure. We aimed to provide a concise review of benchmark findings in important neurobiological systems related to the aetiology and maintenance of PTSD symptomology. Specifically, we discuss functional aetiologies in the noradrenergic, serotonergic, endogenous cannabinoid and opioid systems as well as the hypothalamic-pituitary adrenal (HPA) axis. This article provides a succinct framework to appreciate the current understanding of neurobiological mechanisms related to the pathophysiology of PTSD and how these findings may impact the development of future, targeted pharmacological treatments for this debilitating disorder.

Abstract
The relationship between social support, mental health, and posttraumatic stress disorder (PTSD) symptomatology was investigated in a sample of 229 former New Zealand military personnel. It was hypothesised that veterans reporting greater satisfaction with their social support networks would also report better mental health and lower levels of PTSD symptomatology, and that social support would buffer the relationship between trauma and PTSD. The number of social supports was expected to be unrelated to both PTSD and mental health. Among the subsample of combat veterans (N = 166), results from multiple regression analyses revealed that satisfaction with social support was significantly related to PTSD severity but unrelated to general mental health. The moderating model of social support on the relationship between trauma and PTSD was not supported in hierarchical regression analysis in the total sample (N = 229). Methodological limitations and other explanations for these results are discussed.

Abstract
Life course epidemiology seeks to understand how determinants of health and disease interact across the span of a human life, and has made significant contributions to understanding etiological mechanisms in many chronic diseases, including schizophrenia. The life course approach is ideal for understanding depression: causation in depression appears to be multifactorial, including interactions between genes and stressful events, or between early life trauma and later stress in life; timing of onset and remission of depression varies widely, indicating differing trajectories of symptoms over long periods of time, with possible differing causes and differing outcomes; and early life events and development appear to be important risk factors for depression, including exposure to acute and chronic stress in the first years of life. To better understand etiology and outcome of depression, future research must move beyond basic epidemiologic techniques that link specific exposures to specific outcomes and embrace life course principles and methods. Time-sensitive modelling techniques that are able to incorporate multiple interacting factors across long periods of time, such as structural equation models, will be critical in understanding the complexity of causal and influencing factors from early development to the end stages of life. Using these models to identify key pathways that influence trajectories of depression across the life course will help guide prevention and intervention.

Abstract
BACKGROUND Major depression (MD) and posttraumatic stress disorder (PTSD) are highly comorbid. The degree to which a common genetic liability explains the etiology of the MD-PTSD association has not been quantified and has important implications for research and prevention. METHODS This paper presents an analysis of data from 6744 members of the Vietnam Era Twin Registry. MD and PTSD were assessed using the Diagnostic Interview Schedule-III-R in 1991-92. Bivariate twin modeling was conducted to determine the genetic and environmental etiology of the MD-PTSD association. RESULTS The best-fitting model for the MD-PTSD association included a substantial genetic correlation (r=.77; 95% CI, .50-1.00) and a modest individual-specific environmental correlation (r=.34; 95% CI, .19-.48). Common genetic liability explained 62.5% of MD-PTSD comorbidity. Genetic influences common to MD explained 15% of the total variance in risk for PTSD and 58% of the genetic variance in PTSD. Individual-specific environmental influences common to MD explained only 11% of the individual-specific environmental variance in PTSD. LIMITATIONS Our participants were male Vietnam era veterans and our findings may not generalize to civilians, females or other cohorts. CONCLUSIONS MD-PTSD comorbidity is largely explained by common genetic influences. Substantial genetic overlap between MD and PTSD implies that genes implicated in the etiology of MD are strong candidates for PTSD and vice versa. Environmental influences on MD and PTSD explain less of their covariation and appear to be largely disorder-specific. Research is needed to identify environmental factors that influence the development of MD versus PTSD in the context of common genetic liability.

Abstract
The purpose of the study was to evaluate the potential efficacy and acceptability of accupuncture for posttraumatic stress disorder (PTSD). People diagnosed with PTSD were randomized to either an empirically developed accupuncture treatment (ACU), a group cognitive-behavioral therapy (CBT), or a wait-list control (WLC). The primary outcome measure was self-reported PTSD symptoms at baseline, end treatment, and 3-month follow-up. Repeated measures MANOVA was used to detect predicted Group X Time effects in both intent-to-treat (ITT) and treatment completion models. Compared with the WLC condition in the ITT model, accupuncture provided large treatment effects for PTSD (F [1, 46] = 12.60; p < 0.01; Cohen's d = 1.29), similar in magnitude to group CBT (F [1, 47] = 12.45; p < 0.01; d = 1.42) (ACU vs. CBT, d = 0.29). Symptom reductions at end treatment were maintained at 3-month follow-up for both interventions. Accupuncture may be an efficacious and acceptable nonexposure treatment option for PTSD. Larger trials with additional controls and methods are warranted to replicate and extend these findings.

Abstract
The psychosocial issues related to deployment and combat duty are complex. Deployment may result in psychiatric casualties that are either the result of inadequate coping with the stressors of deployment or acute stress reactions caused by the trauma of battle, that is, combat stress reactions. Combat duty is associated with traumatic events, deprivation, and exposure to war atrocities that may result in acute, delayed or chronic psychosocial issues during and afer returning from deployment. Although protective and mediating factors ar in place, 11% to 17% of combat veterans are at risk for mental disorders in 3 to 4 months after return from combat duty. Combat veterans include service members directly involved in combat as well as those providing support to combatants, that is, nurses. All combat veterans are at risk for experiencing the negative effects of deployment. Frequent deployments of active duty, reserve, and National Guard members have become commonplace. This translates into a disruption of live for anyone associated with the military, as well as an increased focus on the psychosocial impact of combat across the nation. Modern warfare has resulted in multiple changes in policy that govern military operations. Initiatives that focus on the stabilization of service members and their families may impact mental health outcomes of service members returning from combat duty. An initiative toward decreasing the stigma of receiving mental health care is warranted. Mental health issues must be addressed before and during deployment to ensure optimum individual and unit functioning. Early identification and treatment of mental health problems may decrease the psychosocial impact of combat and thus prevent progression to more chronic and severe psychopathology such as depression and PTSD.

Abstract
Past research into the psychological consequences of traumatic events has largely focused on post-traumatic stress disorder (PTSD), although other anxiety disorders and depression are also common in the aftermath of trauma. Little is known about differential predictors of these conditions. The present study investigated the extent to which theoretically derived cognitive variables predict PTSD, phobias and depression after motor vehicle accidents. The cognitive predictors were compared to a set of established, mainly non-cognitive predictors. In addition, we tested how disorder-specific the cognitive predictors are. Participants (n=101) were interviewed within a year after having been injured in a motor vehicle accident. Diagnoses of PTSD, travel phobias and depression, symptom severities and predictor variables were assessed with self-report questionnaires and structured interviews. In multiple regression analyses, the sets of cognitive variables derived from disorder-specific models explained significantly greater proportions of the variance of the symptom severities than the established predictors (PTSD 76% vs. 45%, depression 72% vs. 46% and phobia 66% vs. 40%), and than cognitive variables derived from the models of the other disorders. In addition, the majority of individual cognitive variables showed the expected pattern of differences between diagnostic groups. The results support the hypothesis that disorder-specific sets of cognitive factors contribute to the development and maintenance of PTSD, phobias and depression following traumatic events.

Abstract
OBJECTIVE To screen for posttraumatic stress disorder (PTSD) in primary care patients 7-16 months after 9/11 attacks and to examine its comorbidity, clinical presentation and relationships with mental health treatment and service utilization. METHOD A systematic sample (n=930) of adult primary care patients who were seeking primary care at an urban general medicine clinic were interviewed using the PTSD Checklist: the Primary Care Evaluation of Mental Disorders (PRIME-MD) Patient Health Questionnaire and the Medical Outcome Study 12-Item Short Form Health Survey (SF-12). Health care utilization data were obtained by a cross linkage to the administrative computerized database. RESULTS Prevalence estimates of current 9/11-related probable PTSD ranged from 4.7% (based on a cutoff PCL-C score of 50 and over) to 10.2% (based on the DSM-IV criteria). A comorbid mental disorder was more common among patients with PTSD than patients without PTSD (80% vs. 30%). Patients with PTSD were more functionally impaired and reported increased use of mental health medication as compared to patients without PTSD (70% vs. 18%). Among patients with PTSD there was no increase in hospital and emergency room (ER) admissions or outpatient care during the first year after the attacks. CONCLUSIONS In an urban general medicine setting, 1 year after 9/11, the frequency of probable PTSD appears to be common and clinically significant. These results suggest an unmet need for mental health care in this clinical population and are especially important in view of available treatments for PTSD.

Abstract
BACKGROUND Debate surrounds the nature of gender differences in rates of posttraumatic stress disorder (PTSD). OBJECTIVE The goal of this study was to quantify and explore the reasons for gender differences in rates of PTSD in low income, primary care patients after the World Trade Center (WTC) attack of September 11, 2001. METHODS A survey was conducted at a large primary care practice in New York City 7 to 16 months after the WTC attack. The study involved a systematic sample of primary care patients aged 18 to 70 years. The main outcome measures were the Life Events Checklist, the Posttraumatic Stress Disorder Checklist-Civilian Version, and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire, all administered by a bilingual research staff. RESULTS A total of 3807 patients were approached at the primary care clinic. Of the 1347 who met eligibility criteria, 1157 (85.9%) consented to participate. After the addition of the WTC/PTSD supplement to the study, the total number of patients was 992, of whom 982 (99.0%) completed the survey. Both sexes had high rates of direct exposure to the WTC attack and high rates of lifetime exposure to stressful life events. Overall, females had lower rates of exposure to the attack compared with males (P < 0.05). Hispanic females had the highest rate of PTSD in the full sample. Gender differences in rates of PTSD were largely accounted for by differences in marital status and education. The rate of current major depressive disorder (MDD) was higher in females than in males (P < 0.001), and the reverse was true for substance abuse (P < 0.001). Gender differences for MDD and substance abuse persisted even after adjustments for demographic differences between the sexes. CONCLUSIONS The increased rate of PTSD in women attending a primary care clinic was mediated by their social and economic circumstances, such as living alone without a permanent relationship and with little education or income. The increased rate of MDD in women appeared to be less dependent on these circumstances. These findings have implications for the treatment of women with PTSD in primary care and for research on gender differences in rates of psychiatric disorders.

Abstract
Post-traumatic stress disorder (PTSD) is frequently comorbid with depression. A number of studies have been conducted to compare individuals suffering from comorbid PTSD and depression with individuals suffering from PTSD alone or depression alone. Comorbidity of PTSD and depression is associated with more severe symptoms as well as higher levels of disability compared to individuals with PTSD alone. A severity of overall symptoms is three to fivefold greater in subjects with comorbid PTSD and depression compared to those with PTSD alone. The comorbid group is five times more likely to manifest functional impairment compared to those diagnosed with PTSD alone. Patients with comorbid PTSD and depression have higher depression, impulsivity, and hostility scores and are significantly more likely to make a suicide attempt compared to subjects with depression alone. Depressed subjects with comorbid PTSD tend towards earlier age of first hospitalization and a higher number of hospitalizations compared to depressed individuals without comorbid PTSD. Lower affinity of alpha-2 adrenoreceptors and higher plasma tyrosine availability to the brain are associated with comorbid PTSD and depression, but not with PTSD alone. Individuals with comorbid PTSD and depression do not exhibit the classic rapid eye movement sleep architectural modifications associated with depression, despite the fact that several other psychophysiological indices of dysphoria are detectable in their sleep. In fenfluramine challenge studies, depressed patients with comorbid PTSD have lower plasma cortisol compared to depressed patients without comorbid PTSD. Cortisol levels increase with age and the number of previous major depressive episodes is a predictor of the cortisol response to fenfluramine administration in depressed patients without PTSD, but not in depressed patients with comorbid PTSD. Depressed subjects with comorbid PTSD have higher cerebrospinal fluid homovanillic acid levels compared with depressed subjects without comorbid PTSD. Thus, studies suggest that patients suffering from comorbid PTSD and depression differ clinically and biologically from individuals with PTSD alone or depression alone. It is possible that some or all individuals diagnosed with comorbid PTSD and depression have a separate psychobiological condition that can be termed "post-traumatic mood disorder". Future clinical and neurobiological studies may not only advance our understanding of the role of environmental and genetic factors in the etiology and pathogenesis of stress-related disorders, but also be useful in refining conceptions of stress-related disorders themselves and possible approaches to the treatment of these conditions.

Abstract
This study examined the lifetime prevalence of trauma exposure and posttraumatic stress disorder (PTSD) and their demographic, diagnostic, and trauma-related correlates in a clinical cohort of 426 patients with a first psychiatric admission for psychosis. The prevalence of trauma exposure was 68.5%. Female gender and substance abuse were risk factors for trauma exposure. The prevalence of PTSD was 14.3% in the full sample and 26.5% in those with trauma exposure. PTSD was less prevalent in patients with bipolar disorder and schizophrenia and was twice as common in women. Other significant risk factors were younger age and trauma exposure that was repeated and ongoing or that involved childhood victimization. The findings highlight the importance of systematically ascertaining trauma histories in patients with psychotic disorders.
