Abstract
The Trauma Symptom Inventory-Second Edition (TSI-2) is garnering research interest as a symptom validity test in the evaluation of trauma-related disorders. However, there has been limited empirical validation of its validity scales in clinical and forensic real-world settings. This study evaluated the ability of the TSI-2 Atypical Response (ATR) scale to discriminate response bias in cognitive performance and symptom reporting in a large sample of disability and compensation-seeking claimants. This retrospective chart review included 296 adults with a known history of trauma exposure or claimed trauma-related psychological injury who underwent neuropsychological and/or comprehensive psychological assessment in a private neuropsychology clinic. The discriminability of the ATR scale to classify credible versus non-credible cognitive profiles and symptom reporting were analyzed by AUC-ROCs. Overall, the ATR scale demonstrated poor discriminability of assessment validity based on the Word Memory Test, Victoria Symptom Validity Test, and Minnesota Multiphasic Personality Inventory-2-Restructured Form. The ATR scale had fair discriminatory ability of only one of the over-reporting scales (F-r), with an ROC area of .73, p = .001. However, the test publisher's proposed ATR cut-offs of ≥8 for screening, research, and normal groups, and ≥15 in forensic and clinical settings revealed significant issues with sensitivity and specificity. These results suggest that the TSI-2 should be paired with other established performance validity and symptom validity tests in clinical assessments and not be used as the primary or sole indicator of assessment validity.

Abstract
Posttraumatic stress disorder (PTSD) is one of the most serious and incapacitating mental diseases that can result from trauma exposure. The exact prevalence of this disorder is not known as the literature provides very different results, ranging from 2.5% to 74%. The aim of this umbrella review is to provide an estimation of PTSD prevalence and to clarify whether the prevalence depends on the assessment methods applied (structured interview v. self-report questionnaire) and on the nature of the traumatic event (interpersonal v. not-interpersonal). A systematic search of major databases and additional sources (Google Scholar, EBSCO, Web of Science, PubMed, Galileo Discovery) was conducted. Fifty-nine reviews met the criteria of this umbrella review. Overall PTSD prevalence was 23.95% (95% confidence interval 95% CI 20.74-27.15), with no publication bias or significant small-study effects, but a high level of heterogeneity between meta-analyses. Sensitivities analyses revealed that these results do not change after removing meta-analysis also including data from underage participants (23.03%, 95% CI 18.58-27.48), nor after excluding meta-analysis of low quality (24.26%, 95% CI 20.46-28.06). Regarding the impact of diagnostic instruments on PTSD prevalence, the results revealed a lack of significant differences in PTSD prevalence when structured v. self-report instruments were applied (p = 0.0835). Finally, PTSD prevalence did not differ following event of intentional (25.42%, 95% CI 19.76-31.09) or not intentional (22.48%, 95% CI 17.22-27.73) nature (p = 0.4598). The present umbrella review establishes a robust foundation for future research and provides valuable insights on PTSD prevalence.

Abstract
Post-traumatic stress disorder (PTSD) can become a chronic and severely disabling condition resulting in a reduced quality of life and increased economic burden. The disorder is directly related to exposure to a traumatic event, e.g., a real or threatened injury, death, or sexual assault. Extensive research has been done on the neurobiological alterations underlying the disorder and its related phenotypes, revealing brain circuit disruption, neurotransmitter dysregulation, and hypothalamic–pituitary–adrenal (HPA) axis dysfunction. Psychotherapy remains the first-line treatment option for PTSD given its good efficacy, although pharmacotherapy can also be used as a stand-alone or in combination with psychotherapy. In order to reduce the prevalence and burden of the disorder, multilevel models of prevention have been developed to detect the disorder as early as possible and to reduce morbidity in those with established diseases. Despite the clinical grounds of diagnosis, attention is increasing to the discovery of reliable biomarkers that can predict susceptibility, aid diagnosis, or monitor treatment. Several potential biomarkers have been linked with pathophysiological changes related to PTSD, encouraging further research to identify actionable targets. This review highlights the current literature regarding the pathophysiology, disease development models, treatment modalities, and preventive models from a public health perspective, and discusses the current state of biomarker research.

Abstract
Psychological trauma has developed into a very common concept in the scientific community, in mental health care, as well as in popular language and mass media. The purpose of this article is to show the relevance of the discipline of traumatic stress studies to the field of public mental health by examining central concepts and findings concerning trauma and its aftermath and examining implications for public mental health. Attention is paid to the diagnosis of posttraumatic stress disorder (PTSD) and the construct of resilience as well as to specific areas of public mental health activities. A public mental health perspective will help to develop preventive approaches to trauma and extend the impact of various forms of interventions. It will also make clear that trauma care will have to consider the community and the society at large.

Abstract
The World Health Organization's proposals for posttraumatic stress disorder (PTSD) in the 11th edition of the International Classification of Diseases, scheduled for release in 2018, involve a very brief set of symptoms and a distinction between two sibling disorders, PTSD and Complex PTSD. This review of studies conducted to test the validity and implications of the diagnostic proposals generally supports the proposed 3-factor structure of PTSD symptoms, the 6-factor structure of Complex PTSD symptoms, and the distinction between PTSD and Complex PTSD. Estimates derived from DSM-based items suggest the likely prevalence of ICD-11 PTSD in adults is lower than ICD-10 PTSD and lower than DSM-IV or DSM-5 PTSD, but this may change with the development of items that directly measure the ICD-11 re-experiencing requirement. Preliminary evidence suggests the prevalence of ICD-11 PTSD in community samples of children and adolescents is similar to DSM-IV and DSM-5. ICD-11 PTSD detects some individuals with significant impairment who would not receive a diagnosis under DSM-IV or DSM-5. ICD-11 CPTSD identifies a distinct group who have more often experienced multiple and sustained traumas and have greater functional impairment than those with PTSD.

Abstract
PURPOSE OF REVIEW Since 1980, posttraumatic stress (PTS) disorder has been controversial because of its origin as a social construct, its discriminating trauma definition, and the Procrustean array of symptoms/clusters chosen for inclusion/exclusion. This review summarizes the history of trauma-related nosology and proposed changes, within current categorical models (trauma definitions, symptoms/clusters, subtypes/specifiers, disorders) and new models. RECENT FINDINGS Considering that trauma is a risk factor for virtually all mental disorders (particularly depressive, anxiety, dissociative, personality), the multi-finality of trauma (some survivors are resilient, and some develop PTS and/or non-PTS symptoms), and the various symptoms that trauma survivors express (mood, cognitive, perceptual, somatic), it is difficult to classify PTS. Because the human mind best comprehends categories, reliable classification generally necessitates using a categorical nosology but PTS defies categories (internalizing and/or externalizing, fear-based and/or numbing symptoms), the authors conclude that PTS-like DSM-5's panic attacks specifier-is currently best conceptualized as a specifier for other mental disorders.

Abstract
Background: There is an ongoing debate about the validity of the A1 criterion of PTSD. Whereas the DSM-5 has opted for a more stringent A1 criterion, the ICD-11 will leave it out as a key criterion. Objective: Here we investigated whether formal DSM-IV-TR traumatic (A1) and stressful (non-A1) events differ with regard to PTSD symptom profiles, and whether there is a gender difference in this respect. Method: This was examined in a large, mostly clinical sample from the Netherlands Study of Depression and Anxiety (n = 1433). Participants described their most bothersome (index) event and were assigned to either an A1 or non-A1 event group according to this index event. Results: Remarkably, in men PTSD symptoms were even more severe after non-A1 than A1 events, whereas in women symptoms were equally severe after non-A1 and A1 events. Moreover, while women showed significantly higher PTSD symptoms after A1 events than men (29.9 versus 15.4% met PTSD criteria), there was no gender difference after non-A1 events (women: 28.2%; men: 31.3%). Furthermore, anxiety and perceived impact were higher in women than men, which was associated with PTSD symptom severity. Conclusion: In sum, while women showed similar levels of PTSD symptoms after both event types, men reported even higher levels of PTSD symptoms after non-A1 than A1 events. These findings shed a new light on the role of gender in PTSD symptomatology and the clinical usefulness of the A1 criterion.

Abstract
The first part of the series of three articles on posttraumatic stress disorder (PTSD) in Court to appear in the journal reviews the history of the construct of PTSD and its presentation in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; American Psychiatric Association, 2013) and the ICD-11 (International Classification of Diseases, 11th Edition; World Health Organization, 2018). There are 20 symptoms of PTSD in the DSM-5. PTSD symptoms are arranged into a four-cluster model, which has received partial support in the literature. Other four-factor models have been found that fit the data even better than that of the DSM-5. There is a five-factor dysphoria model and two six-factor models that have been found to fit better the DSM-5 PTSD symptoms. Finally, research is providing support for a hybrid seven-factor model. An eighth factor on dissociation seems applicable to the minority of people who express the dissociative subtype. At the epidemiological level, individuals can expect trauma exposure to take place about 70% over one's lifetime. Also, traumatic exposure leads to traumatic reactions in about 10% of cases, with PTSD being a primary diagnosis for trauma. Once initiated, PTSD becomes prolonged in about 10% of cases. Polytrauma and comorbidities complicate these prevalence statistics. Moreover, the possibility of malingered PTSD presents confounds. However, the estimate for malingered PTSD varies extensively, from 1 to 50%, so that the estimate is too imprecise for use in court without further research. This first article in the series of three articles appearing in the journal on PTSD in Court concludes with discussion of complications related to comorbidities and heterogeneities, in particular. For example, PTSD and its comorbidities can be expressed in over one quintillion ways. This complexity in its current structure in the DSM-5 speaks to the individual differences involved in its expression.
