Primary Outcome Measures

Name	Time	Method
Change From Baseline to Day 28 in Positive and Negative Syndrome Scale (PANSS) Total Score	28 days	The PANSS is a 30-item scale used to measure symptoms of schizophrenia. The scale has 7 positive symptom items, 7 negative symptom items, and 16 general psychopathology symptom items. Each item is scored on a 7-point scale by the clinical rater based on a clinical interview with the patient, with a score of 1 indicating the absence of symptoms and a score of 7 indicating extremely severe symptoms. Thus, the PANSS Total score minimum is 30 and the maximum is 210, with higher numbers indicating more severe symptoms.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline to Day 28 in Clinical Global Impressions-Severity of Illness Scale	28 days	The Clinical Global Impressions (CGI) Scale is a standardized assessment tool that the clinician can use to rate the severity of illness, change over time, and efficacy of medication, taking into account the subject's clinical condition and the severity of side effects. The CGI Scale consists of 3 global subscales, only one of which was used in the present study. The first subscale, Severity of Illness (CGI-S), assesses the clinician's impression of the subject's current illness state; it is often used both before and after treatment. Scores on the Severity of Illness subscale range from 1 = "not ill" at all to 7 = "among the most extremely ill."
