OBJECTIVE Numerous studies of both clinical and large-scale population based samples have demonstrated that adverse childhood events are risk factors for subsequent psychosis. This study assessed the relationships between adverse childhood events and auditory and visual hallucinatory experiences. METHOD The study analysed data from the National(More)

Sexual trauma among females, however, has also been shown to enhance the risk for further revictimisation.

Furthermore, with an increase in access to technology, electronic aggression should also be considered. The authors examined the psychometric properties of the Multidimensional Peer(More)

Many individuals however who have experienced psychosis have never been sexually abused in childhood and many individuals who have experienced CSA have never experienced psychosis. METHOD The current study(More)
PURPOSE Recurring evidence seems to suggest that sexual trauma in childhood may moderate associations between cannabis consumption and psychosis. It has also been suggested, however, that poor childhood mental health may explain linkages between these phenomena. METHODS The current study, using data from the National Comorbidity Survey-Replication (N =(More)
