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.

    Baseline vs. Week 16

Secondary Outcomes (5)

  • Cognitive Deficits, as Measured by the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Cognitive Battery Composite Score

    Measured at Week 16

  • Positive Sub Scale of the Positive and Negative Syndrome Scale (PANSS)

    Baseline vs. Week 16

  • Scale for Assessment of Negative Symptoms (SANS)

    Baseline vs. Week 16

  • Positive and Negative Syndrome Scale (PANSS) and FOLH1, MTHRF, MTR, and COMT Genotype

    Baseline vs. Week 16

  • Relationship Between Response of Negative and Positive Symptoms and the Change in RBC Folate, Serum Folate, Serum B12, and Plasma Homocysteine Concentrations

    Measured at Week 16
