Outcome Measures
Primary Outcomes (1)
Positive and Negative Syndrome Scale (PANSS)
The change from baseline on the Positive and Negative Syndrome Scale (PANSS).The PANNS has three subscales: positive (score range 7-49), negative (score range 7-49), and general psychopathology (score range 16-112). The PANSS positive symptom sub-scale is comprised of 7 items rated on a scale of 1-7, representing positive symptoms of schizophrenia. The PANSS negative symptom subscale is comprised of 7 items rated on a scale of 1-7 representing the negative symptoms of schizophrenia, and the general psychopathology subscale is comprised of 16 items rated on a scale of 1-7 representing symptoms of general psychopathology in mental illness. The total score was computed by adding all the items on the sub-scale together. Scores reported are change in symptoms per week, relative to baseline. A negative score represents a decrease in total PANSS score per week, whereas a positive score represents an increase in total PANSS score per week.
