There is abundant evidence showing a strong association between trauma exposure, psychotic symptoms, and posttraumatic stress disorder (PTSD). Early trauma exposure contributes to the formation of psychotic symptoms and the development of psychotic disorders or severe mental illnesses such as schizophrenia, bipolar disorder, and treatment-refractory major depression. Furthermore, among persons with psychotic disorders, multiple traumatization over the lifetime is common, due to factors such as social stigma, the criminalization of severe mental illness, and increased vulnerability to interpersonal victimization. In addition to these factors is the traumatic nature of experiencing psychotic symptoms and coercive treatments such as involuntary hospitalization and being placed in seclusion or restraints. Not surprisingly, these high rates of trauma lead to high rates of PTSD in people with psychotic disorders, which are associated with more severe symptoms, worse functioning, and greater use of acute care services. In addition to the impact of trauma on the development of psychotic disorders and comorbid PTSD, traumatic experiences such as childhood sexual and physical abuse can shape the nature of prominent psychotic symptoms such as the content of auditory hallucinations and delusional beliefs. Additionally, traumatic experiences have been implicated in the role of ‘stress responsivity’ and increased risk for transition to psychosis in those identified as being at clinical high risk of developing psychosis. Finally, although the diagnostic criteria for PTSD primarily emphasize the effects of trauma on anxiety, avoidance, physiological over-arousal, and negative thoughts, it is well established that PTSD is frequently accompanied by psychotic symptoms such as hallucinations and delusions that cannot be attributed to another DSM-V Axis I disorder such as psychotic depression or schizophrenia. Understanding the contribution of traumatic experiences to the etiology of psychosis and other symptoms can inform the provision of cognitive behavioral therapy for psychosis, including the development of a shared formulation of the events leading up to the onset of the disorder, as well as other trauma-informed treatments that address distressing and disabling symptoms associated with trauma and psychosis. Until recently the trauma treatment needs of this population have been neglected, despite the high rates of trauma and PTSD in persons with psychotic disorders, and in spite of substantial gains made in the treatment of PTSD in the general population. Fortunately, progress in recent years has provided encouraging evidence that PTSD can be effectively treated in people with psychotic disorders using interventions adapted from PTSD treatments developed for the general population. In contrast to clinician fears about the untoward effects of trauma-focused treatments on persons with a psychotic disorder, research indicates that post-traumatic disorders can be safely treated, and that participants frequently experience symptom relief and improved functioning. There is a need to develop a better understanding of the interface between trauma, psychosis, and post-traumatic disorder. This Frontiers Research Topic is devoted to research addressing this interface.

An invaluable sourcebook on the complex relationship between psychosis, trauma, and dissociation, thoroughly revised and updated This revised and updated second edition of Psychosis, Trauma and Dissociation offers an important resource that takes a wide-ranging and in-depth look at the multifaceted relationship between trauma, dissociation and psychosis. The editors – leaders in their field – have drawn together more than fifty noted experts from around the world, to canvas the relevant literature from historical, conceptual, empirical and clinical perspectives. The result documents the impressive gains made over the past ten years in understanding multiple aspects of the interface between trauma, dissociation and psychosis. The historical/conceptual section clarifies the meaning of the terms dissociation, trauma and psychosis, proposes dissociation as central to the historical concepts of schizophrenia and borderline personality disorder, and considers unique development perspectives on delusions and the onset of schizophrenia. The empirical section of the text compares and contrasts psychotic and dissociative disorders from a wide range of perspectives, including phenomenology, childhood trauma, and memory and cognitive disturbances, whilst the clinical section focuses on the assessment, differential diagnosis and treatment of these disorders, along with proposals for new and novel hybrid disorders. This important resource: • Offers extensive updated coverage of the field, from all relevant perspectives • Brings together in one text contributions from scholars and clinicians working in diverse geographical and theoretical areas • Helps define and bring cohesion to this new and important field • Features nine new chapters on: conceptions of trauma, dissociation and psychosis, PTSD with psychotic features, delusions and memory, trauma treatment of psychotic symptoms, and differences between the diagnostic groups on hypnotizability, memory disturbances, brain imaging, auditory verbal hallucinations and psychological testing Written for clinicians, researchers and academics in the areas of trauma, child abuse, dissociation and psychosis, but relevant for psychiatrists, psychologists and psychotherapists working in any area, the revised second edition of Psychosis, Trauma and Dissociation makes an invaluable contribution to this important evolving field.

The Editors have a good reputation in this field. The book also has a good line-up of contributors. Provides a new approach to understanding the experience of psychosis that will have implications for clinicians, patients and researchers.

"In the second edition of this handbook, experts on traumatic stress have contributed chapters on topics spanning classification, epidemiology and special populations, theory, assessment, prevention/early intervention, treatment, and dissemination and treatment.

Social psychiatry is concerned with the effects of the social environment on the mental health of the individual, and with the effects of the person with a mental disorder on his/her social environment. The field encompasses social interventions, prevention and the promotion of mental health. This new edition of Principles of Social Psychiatry provides a broad overview of current thinking in this expanding field and will be a source of ideas both in research and for the management of mental disorder. It opens by putting social psychiatry in perspective, within both psychiatry and the social sciences. From the patient's perspective, the outermost influence is the culture in which they live, followed by their neighbourhoods, workmates, and friends and family. The next section considers how we conceptualize the social world, from families through cultural identify and ethnicity to the wider social environment. The book reviews the social determinants and consequences of the major mental disorders before considering interventions and service delivery at various levels to mitigate these. It closes with a review of the social impact of mental illness around the world and a thoughtful essay by the editors on the current state of social psychiatry and where it is heading.

The first systematic analysis of the rates, risk factors, consequences and global burden of trauma and PTSD across the globe.

Over 100 researchers from 16 countries contribute to the first comprehensive handbook on post-traumatic stress disorder. Eight major sections present information on assessment, measurement, and research protocols for trauma related to war veterans, victims of torture, children, and the aged. Clinicians and researchers will find it an indispensible reference, touching on such disciplines and psychiatry, psychology, social work, counseling, sociology, neurophysiology, and political science.
