Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Categorical Scores on Clinical Global Impression - Improvement (CGI-I)
Time Frame: Baseline, 3 months, 6 months, 1 year, 3 years, 5 years, End of Study [LOCF]
CGI-I consists of a 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale.
Baseline, 3 months, 6 months, 1 year, 3 years, 5 years, End of Study [LOCF]
Change From Baseline in CGI-I at End of Study (up to 5 Years)
Time Frame: Baseline, up to 5 years (End of Study [LOCF])
CGI-I consists of a 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. Change from baseline is score at observation minus score at baseline.
Baseline, up to 5 years (End of Study [LOCF])
Number of Participants With Categorical Scores on Clinical Global Impression of Severity (CGI-S)
Time Frame: Baseline, 3 months, 6 months, 1 year, 3 years, 5 years, End of Study [LOCF]
CGI-S Scale: standardized assessment tool to rate severity of subject's illness; assessed investigator's impression of subject's current illness state. Score: 1 (normal - not ill at all) to 7 (among the most extremely ill patients).
Baseline, 3 months, 6 months, 1 year, 3 years, 5 years, End of Study [LOCF]
Change From Baseline in CGI-S at End of Study (up to 5 Years)
Time Frame: Baseline, up to 5 years (End of Study [LOCF])
CGI-S Scale: standardized assessment tool to rate severity of subject's illness; assesses investigator's impression of subject's current illness state. Score: 1 (normal - not ill at all) to 7 (among the most extremely ill). Change: score at observation minus score at baseline.
Baseline, up to 5 years (End of Study [LOCF])

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Scores on Patient Preference Scale (PPS)
Time Frame: Baseline, up to 5 years (End of Study)
Patient rated satisfaction scale with responses: Much better, I prefer this medication, Slightly better, About the same, Slightly worse, and Much worse, I much preferred my previous medication.
Baseline, up to 5 years (End of Study)
Change From Baseline in Drug Attitude Inventory (DAI) at End of Study (up to 5 Years)
Time Frame: Baseline, up to 5 years (End of Study)
DAI, a 10-item scale to assess how the attitude of schizophrenia patients toward their medications may affect compliance. Respondents indicate 'true' or 'false' for each item. An overall calculated score ranges from -10 to 10, where a positive score indicated a positive subjective response (compliant), whilst a negative score indicated non-compliance. Change: score at observation minus score at baseline.
Baseline, up to 5 years (End of Study)
