Outcome Measures
Primary Outcomes (3)
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at 8 Weeks
Assessed with the Positive and Negative Syndrome Scale in which a clinician rates various psychotic symptoms on the basis of observation of the participant, interview with the participant, and review of all other available information including informant reports. The scale consists of 30 items which are rated categorically between 1 - no symptoms to 7 - extreme symptoms. The minimal score is 0 and the maximal score is 210, with higher scores reflecting more symptoms. Typically scores \> that 60 are considered clinically significant.
8 weeks
Change From Baseline in PANSS Positive Symptom Subscale Score at 8 Weeks.
The PANSS (described above) includes 7 items that reflect positive psychotic symptoms such as hallucinations and delusions. As are all items within the PANSS, items are categorically rated by the clinician between 0 - no symptoms to 7 extreme symptoms. The minimal score is 0 reflecting no positive symptoms to 49 reflecting that all items were extreme. Higher scores reflect more severe symptoms. Scores above 18 are usually clinically significant.
8 weeks
Change From Baseline in PANSS Negative Symptom Subscale at Week 8
The PANSS (described above) includes 7 items that reflect negative psychotic symptoms such as amotivation and social withdrawal. As are all items within the PANSS, items are categorically rated by the clinician between 0 - no symptoms to 7 extreme symptoms. The minimal score is 0 reflecting no positive symptoms to 49 reflecting that all items were extreme. Higher scores reflect more severe symptoms. Scores above 18 are usually clinically significant.

Limitations and Caveats
The most significant weakness of this study was the sample size, which was sufficient only to detect large differences across the three treatments and limited our ability to identify predictors of response or adverse effects.
