Change From Baseline in the medication satisfaction questionnaire (MSQ) score at Week 8 [ Time Frame: Baseline and Week 8 ] [ Designated as safety issue: No ]
A single-item, global, patient-completed instrument that is read aloud to patients by clinicians designed to assess treatment satisfaction among patients with schizophrenia. It consists of one question: "Overall, how satisfied are you with your current antipsychotic medication(s)?" with responses assessed on a 7-point scale rated as follows: 1 = extremely dissatisfied, 2=very dissatisfied, 3=somewhat dissatisfied, 4=neither satisfied nor dissatisfied, 5=somewhat satisfied, 6 = very satisfied, 7 = extremely satisfied

  • Positive and negative symptoms scale (PANSS) score [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    The PANSS provides a total score (sum of the scores of all 30 items) and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each rated on a scale of 1 (absent) to 7 (extreme). It's designed to capture symptoms of schizophrenia. (Gold standard)
  • Drug Attitude Inventory (DAI)-10 Score [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    DAI-10 is a 10-item scale developed to assess how the attitude of schizophrenia patients toward their medications may affect compliance (-10~+10)
  • Clinical Global Impression-Severity (CGI-S) Score [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    The CGI-S rating scale is used to rate the severity of a patient's psychotic condition on a 7-point scale ranging from 1 (not ill) to 7 (extremely severe)
  • Personal and Social Performance Scale (PSP) [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    This scale assesses the degree of dysfunction a patient exhibits within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (i, absent to vi, very severe) in each of the 4 domains. Based on the four domains there will be one total score. Patient's with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; ≤ 30, functioning so poorly as to require intensive supervision
  • Sleep Visual Analog Scale (Sleep VAS) [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]
    This self-administered scale rates quality of sleep and daytime drowsiness. Patient's will indicate on an 11- point scale (from 0 to 10) how well they have slept in the previous 7 days ("very badly" to "very well") and how often they have felt drowsy within the previous 7 days ("not at all" to "all the time"). On the sleep evaluation scale, score '0' corresponds to 'very badly' and score '10' to 'very well'. On the daytime drowsiness scale, score '0' corresponds to 'not at all' and score '10' to 'all the time
  • Number of patients with adverse events [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: Yes ]
  • Number of patients with vital signs and physical examination [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: Yes ]
  • Number of patients with laboratory test (prolactin, blood glucose, glycosylated hemoglobin, cholesterol, triglyceride) [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: Yes ]
  • Positive and negative symptoms scale (PANSS) [ Time Frame: Baseline to Week 12 ] [ Designated as safety issue: No ]

A Comparative Study of Patient Satisfaction Between Continued Administration of Previous Antipsychotics Versus Switched Administration to Paliperidone ER in Non-satisfied Patients With Previous Antipsychotic Drug
An Open-label, Prospective, Randomized and Comparative Study of Patient Satisfaction Between Continued Administration of Previous Antipsychotics Versus Switched Administration to Paliperidone ER in Non-satisfied Patients With Previous Antipsychotic Drug

The purpose of this study is to compare the patient satisfaction between continued administration of previous antipsychotics versus switched administration to paliperidone ER in non-satisfied patients with previous (paliperidone)

This is a randomized (patients are assigned to intervention by chance), prospective, open-label (all people involved know the identity of the assigned drug), switch study designed to evaluate patient-assessed medication satisfaction after 12 weeks of treatment in patients with schizophrenia. The total duration of this study is 12 weeks. Outpatients who treated atypical antipsychotics and report dissatisfaction (Medication Satisfaction Questionnaire [MSQ] <4) with their current treatment response are eligible to participate in the study. Patients will be randomized into two groups, 1) Patients randomized to an immediate initiation of paliperidone ER for a total 12 weeks 2) Patients randomized to a delayed initiation will continue their previous atypical antipsychotics for 8 weeks and then be initiated on paliperidone ER at Day 56 for 4 weeks. During the study treatment optimization will be done by dose adjustment (dose increase or decrease) and by adding psychotropic agents except the antipsychotics.

    Intervention: Drug: Paliperdidone ER
  • Experimental: Antipsychotics and paliperidone ER
    Delayed initiation included previous atypical antipsychotics for 8 weeks and then be initiated on paliperidone ER at Day 56 for 4 weeks. The atypical antipsychotics includes aripiprazole, olanzapine and risperidone. These antipsychotics belongs to the class of second generation bipolar atypical antipsychotics.
