Background. There is strong evidence that those with a long-standing psychotic disorder have fewer social contacts and less social support than comparison groups. There is less research on the extent of social contacts and support prior to or at the onset of psychosis. In the light of recent evidence implicating a range of social experiences and contexts at(More)
INTRODUCTION Recent models of psychosis implicate stressful events in its etiology. However, while evidence has accumulated for childhood trauma, the role of adult life events has received less attention. Therefore, a review of the existing literature on the relationship between life events and onset of psychotic disorder/experiences is timely. METHODS A(More)
Up to now studies on hypothalamic-pituitary-adrenal (HPA) axis activity in psychosis have shown inconsistent findings. These inconsistencies have been often ascribed to confounding effects of long duration of illness and chronic treatment with psychotropic medications of the subjects studied (chronic psychosis). In the last years, several studies have(More)
While contemporary models of psychosis have proposed a number of putative psychological mechanisms, how these impact on individuals to increase intensity of psychotic experiences in real life, outside the research laboratory, remains unclear. We aimed to investigate whether elevated stress sensitivity, experiences of aberrant novelty and salience, and(More)
There is a substantial body of research reporting evidence of associations between various forms of childhood adversity and psychosis, across the spectrum from experiences to disorder. This has been extended, more recently, to include studies of cumulative effects, of interactions with other factors, of specific effects, and of putative biological and(More)
Childhood adversity (variously defined) is a robust risk factor for psychosis, yet the mitigating effects of social support in adulthood have not yet been explored. This study aimed to investigate the relationships between childhood sexual and physical abuse and adult psychosis, and gender differences in levels of perceived social support. A sample of 202(More)
Oculus Rift, Google Cardboard, Samsung Gear, HTC Vive, all types of virtual reality (VR) headsets are fast becoming recognised household names in an industry primed to be worth an estimated 80 billion dollars within the next 10 years (Goldman Sachs). Not only is this new technology taking the gaming (and other) industries by storm, VR applications are(More)
Recent years have seen considerable progress in epidemiological and molecular genetic research into environmental and genetic factors in schizophrenia, but methodological uncertainties remain with regard to validating environmental exposures, and the population risk conferred by individual molecular genetic variants is small. There are now also a limited(More)
BACKGROUND Evidence has accumulated that implicates childhood trauma in the aetiology of psychosis, but our understanding of the putative psychological processes and mechanisms through which childhood trauma impacts on individuals and contributes to the development of psychosis remains limited. We aimed to investigate whether stress sensitivity and threat(More)
We attempted to explore whether lack of insight in patients with psychosis is related to their genuine inability to recognise symptoms of mental illness as opposed to denial. We addressed this by examining participants' judgments of illness in vignettes in which they were either the protagonist or were commenting on others' behaviour. We recruited 44 first(More)
