Summary
Brief summary
To investigate whether risperidone either alone or in combination with an intensive psychological treatment can delay or prevent the onset of an acute psychotic episode in young people thought to be at heightened risk of illness. The secondary aim was to investigate whether the interventions were effective in reducing general pscyhopathology in the participants whilst improving functioning.
