A definable concept of symptomatic remission in schizophrenia has been proposed by the Remission in Schizophrenia Working Group (RSWG). Nevertheless no studies to date assessed eventual differences in core symptoms at onset between remitters and non-remitters. The present study evaluated whether the severity of core symptoms differed among 48 patients with first episode schizophrenia (FES), and whether it predicted long-term (16-years) remission. Particularly, the present study aimed to verify if RSWG remission criteria might identify a sub-group of patients with mild core symptoms at their first episode. In the present study the severity of core symptoms was significantly lower in remitted than in non-remitted patients; interestingly, five out of the eight core symptoms already satisfied the severity criteria for remission in most remitted patients. Among the core symptoms only the severity of social withdrawal predicted the long-term outcome, while age at onset, duration of untreated psychosis and employment status did not exert any effect. Concluding, patients with FES presenting, mild core symptoms, particularly low negative symptoms, were more likely to reach long-term remission. Therefore, RSWG remission criteria seem to identify a subgroup of FES patients with mild severe core symptoms so with a higher probability to reach remission.
