 The detection of prodromal symptoms and intervention during the prodromal phase preceding the onset of full-blown psychosis are important for preventing the onset of psychosis and improving the prognosis. However, fundamental theories explaining early psychosis have not yet been established. The concept of early intervention for psychosis has not been extensively acknowledged among psychiatric professionals in Japan. By using a questionnaire containing case vignettes describing psychosis prodrome cases and a case of full-blown schizophrenia, we investigated the abilities of Japanese psychiatrists to make a clinical diagnosis and their strategies for treatment. The results suggested that pharmacotherapy might be overused in prodromal cases since the psychiatrists tended to prescribe neuroleptics for positive symptoms before the diagnostic criteria for schizopherenia had been fulfilled. Thus, the criteria for full-blown psychosis need to be reexamined, the risk of a transition from at-risk mental state (ARMS) to psychosis needs to be assessed, and guidelines for pharmacological intervention for the treatment of prodromal symptoms need to be established in Japan.
