Negative childhood experiences and mental health: theoretical, clinical and primary prevention implications

Abstract

After decades of ignoring or minimising the prevalence and effects of negative events in childhood, researchers have recently established that a broad range of adverse childhood events are significant risk factors for most mental health problems, including psychosis. Researchers are now investigating the biological and psychological mechanisms involved. In addition to the development of a traumagenic neurodevelopmental model for psychosis, the exploration of a range of psychological processes, including attachment and dissociation, is shedding light on the specific aetiologies of discrete phenomena such as hallucinations and delusions. It is argued that the theoretical, clinical and primary prevention implications of our belated focus on childhood are profound.
