In order to address the question "should adolescent psychosis be managed in the same way as adult-onset psychosis", three specific objectives were identified:
1. To evaluate the effectiveness of interventions for psychosis in adolescents aged 13-17
2. To evaluate the tolerability and adverse effects of interventions in adolescent psychosis
3. Where possible, to allow objective comparisons to be made between interventions in adolescents and adults in terms of effectiveness, tolerability and adverse effects.
