Symptom remission in first episode patients.

Author information

Department of Psychiatry, University of Calgary, Calgary, Canada.


Recently, new remission criteria for schizophrenia has been proposed, based on low symptom severity of core symptoms (the severity criteria), which is sustained over a minimum of 6 months (time criterion). The purpose of this study was to examine, in a secondary analysis, these criteria in a cohort of 240 first episode patients with a mean follow-up of 26.4 months from the Calgary Early Psychosis Program. Eighty-eight subjects (36.7%) met both the severity criteria and time criteria for remission (in-remission group); 47 subjects (19.6%) met only the severity criteria at their most recent assessment (severity only group); 49 (20.4%) subjects had met severity criteria at one or more assessments but did not meet severity or severity and time at the most recent assessment (fluctuating group); and 56 (23.3%) did not meet remission criteria (non-remission group). Those who achieved remission had lower levels of symptoms and higher functioning at baseline and at the final follow-up assessment, improved premorbid functioning, shorter duration of untreated psychosis and increased changes in symptoms over time.
