Traumatic stress in the 21st century

OBJECTIVE: The introduction to a series of articles on traumatic stress aims to examine the ambivalent relationship between traumatic stress and psychiatry. It provides an outline to the very significant contribution that this field made before the conceptualisation of posttraumatic stress disorder (PTSD) and how the research and theoretical thinking in this field can provide many insights into the relationship between environmental factors and psychological health. It focuses on the relevance of this field to general psychiatry. RESULT: Posttraumatic stress disorder has emerged as the most common anxiety disorder in women. As well, there are high rates discovered in a range of chronically ill psychiatric patient populations. In particular, strategies for dealing with the issues of childhood abuse and neglect are not often considered by adult psychiatric services for the chronically and severely mentally ill, despite there being important predictors of suicidal behaviour, hospitalisation and prolonged disability. An effective consideration of the available evidence is often complicated by concerns about the impact of financial compensation on the presentation of psychopathology. This is a complex social dialectic whose impact is important to the practise of psychiatry. Equally, this field in itself must avoid becoming excessively rigid in its clinical definitions and the particular interventions which are espoused. CONCLUSIONS: The impact of traumatic events on long-term psychological adjustment and physical health have been under estimated. Identification of those at risk is an important issue given that effective treatments are now available. This is an area in which further conceptual thinking is required. It also provides particular opportunities to explore the biological processes of, and interaction between, the environment and the underlying genetic and neurobiological processes which are critical to the modulation of psychopathology.
