Psychotic disorders are experienced by between 100,0000 and 500,000 people in the U.K. at any one time. The symptoms which characterise these disorders are more common in the general population than previously assumed. Studies of both adults and children have demonstrated that up to 70% of non-clinical samples endorse items related to psychotic experiences. Pre-psychosis or psychosis prodrome has been considered influential in the early identification and intervention in psychosis. However the experiences that have been identified as indicators of psychosis are non-specific such as quality and withdrawal and could also be indicative of other psychiatric disorders such as anxiety and depression. Models of psychosis previously focused upon deficits in those with psychosis. Current cognitive models focus more upon thinking biases such as attributional bias or jumping to conclusions. These models move away from the idea that psychosis is experienced by people who are physiologically or biologically different from those who do not. These models are the foundation of current psychological intervention in psychosis and aim to reduce associated stigma and shame. The present study aimed to assess the prevalence of psychotic experiences in a non-clinical sample of school-aged children. Associations with depression, anxiety, stress, bullying and dissociation were also investigated. Nine questionnaires were completed by 308 14 to 16 years olds. results indicated that 98% of the sample endorsed at least one item on the early signs of psychosis measure and 92% endorsed at least one item on both the measures of delusional ideation and hallucinatory experiences. Psychotic experiences were significantly associated with all other factors and those who had been bullied were significantly more likely to report psychotic experiences. This study adds further support to the continuum model of psychosis and clinical practice implications are discussed.
We have developed the following database of research theses on bullying from all academic institutions in the UK and Ireland. The aim of this database is to assist those who are interested in the field of bullying and want to see what research has already been done. We have attempted to ensure that we have included all relevant theses here; but if there is an omission please let us know by emailing geraldine.kiernan@dcu.ie.
The database is here for information purposes. Those who want access to the texts of the theses need to contact the author, the relevant institution, or both.
