Screening of mental health problems in school may prevent psychotic experiences later

Researchers at RCSI University of Medicine and Health Sciences have found in a first-of-its-kind study that screening of mental health problems in school may prevent psychotic experiences later. Further a school-based screen for mental health problems, combined with a referral system, can be effective at improving and protecting the mental health of adolescents.

The research has been published in BMC Public Health. 

It is the first study to examine the impact of school-based interventions on preventing psychotic experiences, an early indicator of developing mental disorders in children and adolescents. Of the interventions tested, one consisting of a universal screener and selective intervention was found to both reduce the rates of, and prevent psychotic experiences at 12-month follow up.

Professor Mary Cannon, Professor of Psychiatric Epidemiology and Youth Mental Health, Department of Psychiatry, RCSI, commented: “Prevention has two key objectives; to reduce the symptoms of mental health disorders, and prevent new incidence of symptoms. This study demonstrates that school-based interventions have the potential to be effective at both key aims of prevention, making a positive impact on public mental health.”

Lead author and RCSI PhD student, Lorna Staines commented: “Psychotic experiences are particularly common in the adolescent population and are associated with a four-fold increased risk for psychotic disorder, and a three-fold increased risk for any mental disorder. This study has for the first time identified school-based programmes as an effective route to prevent psychotic experiences.”
