Primary Outcome Measures

Name	Time	Method
Main Objective: To test the hypothesis that patients with good premorbid functioning, as assessed using the Premorbid Adjustment Scale, will respond better to treatment as measured by changes from baseline on the PANSS total score and CGI-S than patients with poor premorbid functioning.;Secondary Objective: a to assess the effectiveness, safety, tolerability, and functioning of patients in the early phase of psychosis who are treated with of Risperdal Consta asfollows Effectiveness via CGI-S/C, PANSS, retention rate Functioning SF-36 ; rehospitalisation rates Safety and tolerability via reported adverse events, ESRS and retention rate b Examine whether greater insight, as measured by the SAI-E and PANSS, is positively associated with better outcomes;Primary end point(s): Clinical Response improvement rate defined as 20 improvement on PANSS total score from baseline to endpoint.
