Purpose
The purpose of this study is to evaluate efficacy of treatment with paliperidone extended-release (ER) tablets in patients with schizophrenia who were not satisfied with other antipsychotics (Olanzapine, Quetiapine and Risperidone) they had been taking. The safety and tolerability of paliperidone ER tablets will also be assessed.

- Changes in Positive and Negative Symptom Scale (PANSS) total scores [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The PANSS consistes of a total scores (all 30 items) and scores in 3 subscales, positive subscale (7 items), negative subscale (7 items), general psychopathology subscale (16 items). Patients were to be rated in every scale rate from 1(absent) to 7 (extremely serious).
- Change in PANSS subscale scores [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The PANSS consistes of a total scores (all 30 items) and scores in 3 subscales, positive subscale (7 items), negative subscale (7 items), general psychopathology subscale (16 items). Patients were to be rated in every scale rate from 1(absent) to 7 (extremely serious).
- Change in the Clinical Global Impressions (CGI) scale [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The CGI scale is a 7-point scale rating from 1(normal, not at all illness) to 7 (extremely ill). The CGI scales are commonly used measures of symptom severity, treatment response and the efficacy of treatments of patients.
- Change in personal and social function by Personal and Social Performance (PSP) scale [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The PSP scale with its four sub dimensions was used to evaluate the severity of psychosocial functioning in patient within 1month, consisting of a) Socially useful activities; b) personal and social relationships; c) self-care; d) disturbing and aggressive behavior. The scores ranged from 1 to 100, the severity in every sub dimension was divided into 10 equivalent scores range (i, absent-vi, extremely). Score 71-100 indicated mild difficult; score 31-70 various degree of disability; Score≤30 extremely illness, so that intense care was needed.
- Change in patient satisfaction with treatment [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The degrees of satisfaction with present treatment were assessed by a 5-point scale (very satisfied, satisfied, in general, dissatisfied, very dissatisfied).
- Change in sleep quality and level of daytime sleepiness [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The quality of sleep and level of daytime sleepiness in patients were to be assessed, as determined by Visual Analogue scale.
- Percentage of patients with a ≥20% reduction of PANSS total scores at endpoint from baseline [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]The PANSS consistes of a total scores (all 30 items) and scores in 3 subscales, positive subscale (7 items), negative subscale (7 items), general psychopathology subscale (16 items). Patients were to be rated in every scale rate from 1(absent) to 7 (extremely serious).

Detailed Description:
This was a 12-week study designed to determine the efficacy, tolerability and safety of flexible dosage of paliperidone extended-release (ER) tablets in treatment of patients with schizophrenia not satisfied with other prior antipsychotics. During the period of study, the dose of paliperidone ER tablets was adjusted in the range of 3mg-12mg/day, and investigator could select dose for patients by individual dose adjustment. Initial dose for paliperidone extended-release was 6mg/day.
