Overview

The International Society for Traumatic Stress Studies is dedicated to sharing information about the effects of trauma and the discovery and dissemination of knowledge about policy, program and service initiatives that seek to reduce traumatic stressors and their immediate and long-term consequences.
We are Engaged
ISTSS provides a forum for the sharing of research, clinical strategies, public policy concerns and theoretical formulations on trauma around the world. We are the premier society for the exchange of professional knowledge and expertise in the field.
We are Diverse
Members of ISTSS include psychiatrists, psychologists, social workers, nurses, counselors, researchers, administrators, advocates, journalists, clergy, and others with an interest in the study and treatment of traumatic stress.

We are Worldwide
ISTSS members come from a variety of clinical and non-clinical settings around the world, including public and private health facilities, private practice, universities, non-university research foundations and from many different cultural backgrounds.


Acceptance and Commitment Therapy for Trauma: Finding Life Beyond the Pain

Acceptance and Commitment Therapy (ACT) is a principle-based behavioral intervention designed to address human suffering in a mindful and compassionate way. Many individuals who have experienced a trauma suffer due to painful memories, feelings and thoughts related to their traumatic experience. Avoidance or control of these private experiences is often seen as a solution to suffering. This kin...

Cannabis and PTSD: Existing Evidence and Clinical Considerations

Description Dr. Bonn-Miller will provide an overview of cannabis, including associated consequences and benefits stemming from its use. He will then summarize epidemiological data, particularly from the Department of Veterans Affairs (VA), related to recent and emerging trends in cannabis use/disorders, including among veterans with PTSD. Limitations of epidemiological tracking will be discusse...

Dialectical Behavior Therapy (DBT) and the Treatment of Trauma-Related Problems

Description Dialectical Behavior Therapy (DBT; Linehan, 1993) is a comprehensive, cognitive-behavioral treatment with strong empirical support for the treatment of suicidal and self-injurious behaviors, particularly among individuals meeting criteria for borderline personality disorder (BPD). Posttraumatic stress disorder (PTSD) is a common co-occurring diagnosis in this client population and o...

Finding Feeling: Treating Traumatic Dissociation

Trauma is a both a physical and psychological disruption, a discontinuity in experience. The helplessness associated with it challenges a person’s sense of agency and therefore their customary control over mind and body. Dissociative disorders constitute a failure of integration of identity, memory, or consciousness, andmost often occur in the aftermath of trauma. A Dissociative Subtype has be...

Functional Neuroimaging of Neural Circuits in PTSD: From Hyperactive Amygdala to Altered Contextual Processing

The brain mechanisms that lie at the core of PTSD are not yet understood, and may perpetuate or sustain this disorder. Over the past decades, functional neuroimaging studies uncovered a complex network of brain regions involved in PTSD, progressively improving our understanding of the PTSD pathophysiology. The evolution of functional neuroimaging studies from early studies of responses to emotio...

Genomic Regulation by Early Life Experience: Epigenetics and Psychopathology

The early-life environment has important consequences on behavioral development, and specifically, adversity experienced during early life is associated with increased risk for psychopathology in adulthood. Only until recently have we started to uncover some of the mechanisms accounting for the behavioral changes induced by early-life adversity. The epigenome is responsive to the environment and...

How to Treat Concurrent PTSD in Patients with Borderline Personality Disorder: Principles and Evaluation of DBT-PTSD

Approximately 60% of treated patients with borderline personality (BPD) disorders suffer from severe co-occurring posttraumatic stress disorder (PTSD), mostly related to sexual abuse during childhood. Even successful standard dialectical behavior therapy (DBT) requires additional treatment with these clients. In cooperation with M. Linehan at the Central Institute of Mental Health, Mannheim, a t...

Integrating Expert Knowledge About Traumatic Stress Into Statistical Models Assessing Individual Change Over Time by Using Bayesian Statistics

In statistics, tools have been developed to estimate the existence of latent trajectories, where individuals belong to trajectories that are unobserved, can be evaluated: Latent Growth Mixture Modeling (LGMM). Researchers typically have specific expectations about the outcomes of their study, in case of LGMM, these expectations might be concerned with the number and shape of latent trajectories....

The Neurobiology of Traumatic Stress: Key Findings and Methodologies

Recent advances in neuroimaging, biochemistry, and genetics research have paved the way toward a greater understanding of the neurobiology of trauma and stress. As new technologies and methods are discovered and applied to neurobiological work, it becomes increasingly important for individuals interested in treating and studying PTSD to learn the tools necessary to evaluate the latest research ...

Two Empirically Based Models for the Treatment of Complex Trauma in Adolescents: Central Components and Cultural Adaptations

This pre-meeting institute will describe two empirically based treatments (EBTs) developed to treat the immediate and long-term impacts of complex trauma, and will describe cultural adaptations that optimize their effectiveness with socio-culturally marginalized youth. Complex trauma, often involving repeated exposure to multiple forms of childhood abuse, neighborhood violence, and peer assaults...
