Background: Children and adolescents who report psychotic symptoms appear to be at increased risk for psychotic disorders in adulthood - a putative ;symptomatic' high-risk group. However, little research has investigated whether those in this high-risk population have increased rates of exposure to traumatic events in childhood, as seen in patients who have a psychotic illness.Aims: To examine whether adolescents with psychotic symptoms have an increased rate of traumatic experiences.Method: Psychiatric interviews were carried out with 211 adolescents aged between 12 and 15 years and their parents as part of a population-based study. The interview enquired about a number of early traumatic events including physical and sexual abuse, exposure to domestic violence and bullying.Results: Fourteen adolescents (6.6% of those interviewed) reported experiencing at least one psychotic symptom. Adolescents who reported psychotic symptoms were significantly more likely to have been physically abused in childhood, to have been exposed to domestic violence and to be identified as a bully/victim (that is, both a perpetrator and victim of bullying) than those who did not report such symptoms. These findings were not confounded by comorbid psychiatric illness or family history of psychiatric history.Conclusions: Our findings suggest that childhood trauma may increase the risk of psychotic experiences. The characteristics of bully/victims deserve further study. [ABSTRACT FROM AUTHOR]

Background: Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence., Aims: To investigate the relationship between psychotic symptoms and non-psychotic psychopathology in community samples of adolescents in terms of prevalence, co-occurring disorders, comorbid (multiple) psychopathology and variation across early v. middle adolescence., Method: Data from four population studies were used: two early adolescence studies (ages 11-13 years) and two mid-adolescence studies (ages 13-16 years). Studies 1 and 2 involved school-based surveys of 2243 children aged 11-16 years for psychotic symptoms and for emotional and behavioural symptoms of psychopathology. Studies 3 and 4 involved in-depth diagnostic interview assessments of psychotic symptoms and lifetime psychiatric disorders in community samples of 423 children aged 11-15 years., Results: Younger adolescents had a higher prevalence (21-23%) of psychotic symptoms than older adolescents (7%). In both age groups the majority of adolescents who reported psychotic symptoms had at least one diagnosable non-psychotic psychiatric disorder, although associations with psychopathology increased with age: nearly 80% of the mid-adolescence sample who reported psychotic symptoms had at least one diagnosis, compared with 57% of the early adolescence sample. Adolescents who reported psychotic symptoms were at particularly high risk of having multiple co-occurring diagnoses., Conclusions: Psychotic symptoms are important risk markers for a wide range of non-psychotic psychopathological disorders, in particular for severe psychopathology characterised by multiple co-occurring diagnoses. These symptoms should be carefully assessed in all patients.

Objectives: This study examined the prevalence of depressive symptoms, including suicidal ideation/behaviour, among bullied and non-bullied young people., Methods: Participants were 209 students, 97 male and 112 female, attending eight urban post-primary schools and aged between 12 and 15 years. Participants were interviewed using the Schedule for Affective Disorders and Schizophrenia for School Aged Children - Present and Lifetime Version, the Hopelessness Scale for Children, the Scale for Suicide Ideation, and the Suicide Intent Scale., Results: Data were analysed using a series of non-parametric comparison tests. Being a victim of bullying was found to be significantly associated with depression (χ2 = 10.986; df = 1; p = 0.001) and suicidal ideation (χ2 = 5.811; df = 1; p = 0.022). Results also indicated that victims were more likely to have reported a suicide attempt (χ2 = 5.995; df = 1; p = 0.022). Finally, those bullied were significantly more likely to have been referred to psychiatric services (χ2 = 6.661; df = 1;p = 0.011)., Conclusions: These findings suggest that the issue of bullying needs to be re-addressed within Irish schools, with particular emphasis placed on further investigation into the psychological consequences thereof.
