Evaluation of the Functional Remission Occurrence and Predictive Factors in Schizophrenia

Prospective, national, noninterventional study. One year follow up with three evaluation dates (D0, D180 and D360). The participation of a subject in this study will in no way impact the regular care of the subject or any benefits they are otherwise entitled to. All treatment decisions will be made at the discretion of the participating physician, in accordance with his clinical practice and with approved local prescribing information. Only data available from clinical practice will be collected. Evaluation methods: patient history and clinical examination, clinical global impression (CGI): Improvement in CGI, social performance evaluation [functional remission of general schizophrenia (FROGS scale)], clinical remission evaluation: 8 items of the Positive and negative syndrome (PANSS) Scale, psychosocial remission evaluation (PSP scale), current insight evaluation: insight scale for psychosis, subjective well being under neuroleptic treatment (SWN scale), health condition [Euro quality of life - 5 Dimensions (EQ-5D)]; Judgment Criteria: functional remission is defined as an overall score of greater than or equal to (>=) 57 on the FROGS scale, functional response is defined as improvement of >= 7 points on the FROGS scale. Safety evaluation: no tolerance analysis will be performed, adverse event (AE) and serious adverse event (SAE) with J&J products will be collected and transmitted according to J&J timelines/process.
