PALI ER Immediate Initiation
Subjects randomly assigned at the baseline visit to an immediate initiation of paliperidone ER from oral risperidone were to receive blinded paliperidone ER for a total of 6 weeks (Immediate Initiation group).
PALI ER Delayed Initiation
Subjects randomly assigned to a delayed initiation were to receive blinded resperidone at their baseline dose of 4 or 6 mg for 2 weeks and were to be initiated on blinded paliperidone ER at Day 14 for 4 weeks (Delayed Initiation group).

The TSQM is a 14-item subject-assessed evaluation of treatment medication including 4 factors, Effectiveness (items 1-3), Side Effects (items 4-8), Convenience (items 9-11)and Global Satisfaction (items 12-14). Item 14 states "taking all things into account, how satisfied or dissatisfied are you with this medication?" and utilizes the following responses on a 7-point Likert scale: 1=Extremely Dissatisfied, 2=Very Dissatisfied, 3=Somewhat Dissatisfied, 4=Neither Satisfied Nor Dissatisfied, 5=Somewhat Satisfied, 6=Very Satisfied, 7=Extremely Satisfied. Worst value is 0 and best value is 100.

The SF-36 is a well-validated and widely used quality-of-life instrument employed in numerous disease states, including schizophrenia. It is a self-administered survey that measures eight domains of health including: physical functioning, role limitations due to physical health (role-physical), bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems (role-emotional) and general mental health. Scoring of the SF-36 was based on the SF-36 Manual and Interpretation Guide. Worst value is 0 and best value is 100.

The PSQI is a 2-part questionnaire that assesses sleep quality and disturbances in seven domains: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Each domain is rated on a 4-point scale as follows: 0=Not during the past month, 1=Less than once a week, 2=Once or twice a week, 3=Three or more times a week. Total scores range from zero to 21; increasing scores indicate poorer sleep quality and total scores greater than 5 suggest significant sleep disturbance.

The standard COVI Anxiety Scale is an investigator-assessed measure of the severity of anxiety symptoms on 4 items: verbal report, behavior, somatic symptoms, and relationship to study drug. Each dimension is assessed in 5 to 10 minutes using a 5-point scale as follows: 1=Not at all, 2=Somewhat, 3=Moderately, 4=Considerably, to 5=Very much. For this study, the standard COVI Anxiety Scale was modified to improve psychometric properties by incorporating anchor points for symptom severity, frequency, and duration and for functional impairment. Worst value is 20 and best value is 4.

The PANSS is a 30-item scale designed to capture numerous symptoms of schizophrenia, including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale as follows: 1=Absent, 2=Minimal, 3=Mild,4=Moderate, 5=Moderate Severe, 6=Severe, 7=Extreme. This scale has been shown to be sensitive to changes associated with medication treatment. In addition to a total score, this assessment yields separate scores along a Positive Syndrome, a Negative Syndrome, and a General Psychopathology Scales. Worst value is 210, best value is 30.

The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a subject. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill subjects". Worst value is 7 and best value is 1.
