The development of Open Dialogue is linked to evidence of its superiority to normal treatment of acute psychosis. After 5 years (1992–1997) of Open Dialogue treatment in Lapland, 81 % of participants had no remaining psychotic symptoms and 81% had returned to full employment. Only 35 % had used antipsychotic drugs (Seikkula et al., 2006). Similar results emerged from Tornio between 2003 and 2005. In the UK, only 20% of people diagnosed with schizophrenia would be expected to be symptom free after 5 years, with close to 100% of all patients with psychosis receiving antipsychotics.
