|---|---|---|---|
| Primary | Brief Psychiatric Rating Scale (BPRS) Total Score | Baseline | The Brief Psychiatric Rating Scale (BPRS) is an 18-item instrument. The items are anchored on a 7-point scale (higher rating: greater severity). Total scores range from 18 to 126 (higher score: greater severity). The instrument covers areas including: somatic concerns, anxiety, emotional withdrawal, conceptual disorganization, guilt feelings, tension, mannerisms and posturing, grandiosity, depressive mood, hostility, suspiciousness, hallucinatory behavior, motor retardation, uncooperativeness, unusual thought content, blunted affect, excitement and disorientation. |
| Primary | Brief Psychiatric Rating Scale (BPRS) Total Score | Endpoint (12 weeks) | The Brief Psychiatric Rating Scale (BPRS) is an 18-item instrument. The items are anchored on a 7-point scale (higher rating: greater severity). Total scores range from 18 to 126 (higher score: greater severity). The instrument covers areas including: somatic concerns, anxiety, emotional withdrawal, conceptual disorganization, guilt feelings, tension, mannerisms and posturing, grandiosity, depressive mood, hostility, suspiciousness, hallucinatory behavior, motor retardation, uncooperativeness, unusual thought content, blunted affect, excitement and disorientation. |
| Primary | Scale for the Assessment of Negative Symptoms (SANS) | baseline | The Scale for the Assessment of Negative Symptoms (SANS) is a rating scale to measure negative symptoms in schizophrenia. The scale has 25 items (20 individual and 5 global) rated on scale of 0-5 (higher rating: greater severity). SANS is split into 5 domains, and within each domain separate symptoms are rated from 0 (absent) to 5 (severe). Domains include: Affective Flattening or Blunting, Alogia, Avolition - Apathy, Anhedonia - Asociality, Attention. The total range of the SANS is from 0 to 120. |

| Secondary | CGI Severity of Illness Scale (CGI-S) | baseline | CGI Severity of Illness Scale (CGI-S) assesses severity of illness on 1-7 scale. Clinicians' experience is used to gauge the severity of illness from 'normal' (value=1) to 'among the most extremely ill patients' (value=7). The higher rating correlates with more severely ill. |

Clinicians' experience is used to gauge the severity of illness from 'normal' (value=1) to 'among the most extremely ill patients' (value=7). The higher rating correlates with more severely ill. |
| Secondary | CGI Improvement Scale (CGI-I) | Endpoint (12 weeks) | CGI Improvement Scale (CGI-I) higher rating correlates with worsening of condition (vs. improvement with lower rating). The CGI-I is scored from 1 to 7 where 1 = 'very much improved' and 7 = 'very much worse'. Clinicians are asked to rate total improvement in the following manner: "...in your judgement, it is due entirely to drug treatment. Compared to his condition at admission to the project, how much has he changed?" |
| Secondary | Verbal Fluency | Baseline | Verbal fluency was measured using the Controlled Word Association Test (COWAT). There is no range for this measure, as it is not a scale. The subjects can generate as many new words as they can, so there is no maximum. The greater the number of words one generates indicates better performance. |

| Secondary | QTc | Baseline | The QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart. ECG machines calculate a corrected QT (QTc). QTc is the corrected QT interval in the EKG. Normal range is from 430-470ms. |

| Secondary | Processing Speed | Baseline | Processing speed was assessed using using Digit Symbol Coding from the Wechsler Adult Intelligence Scale, Revised (WAIS-R). The tool is used for the assessment of processing speed. The range of scores is 0 to 100- with the higher number indicating greater performance. |
| Secondary | Processing Speed | Endpoint (12 weeks) | Processing speed was assessed using using Digit Symbol Coding from the Wechsler Adult Intelligence Scale, Revised (WAIS-R). The tool is used for the assessment of processing speed. The range of scores is 0 to 100- with the higher number indicating greater performance. |
| Secondary | Verbal Learning and Memory: List A | Baseline | Verbal learning and memory were assessed by the Rey Auditory Verbal Learning Test (RAVLT) List A: Total Trials (1-5). This assessment consists of a list of words that the subject repeats back, it does not have an interpret-able range of scores like a traditional scale. Scores are based on number of words repeated back. |
| Secondary | Verbal Learning and Memory: List A | Endpoint (12 weeks) | Verbal learning and memory were assessed by the Rey Auditory Verbal Learning Test (RAVLT) List A: Total Trials (1-5). This assessment consists of a list of words that the subject repeats back, it does not have an interpret-able range of scores like a traditional scale. Scores are based on number of words repeated back. |
| Secondary | Verbal Learning and Memory: List B | Baseline | Verbal learning and memory were assessed by the Rey Auditory Verbal Learning Test (RAVLT) List B: Single Trial. This assessment consists of a list of words that the subject repeats back, it does not have an interpret-able range of scores like a traditional scale. Scores are based on number of words repeated back. |
| Secondary | Verbal Learning and Memory: List B | Endpoint (12 weeks) | Verbal learning and memory were assessed by the Rey Auditory Verbal Learning Test (RAVLT) List B: Single Trial. This assessment consists of a list of words that the subject repeats back, it does not have an interpret-able range of scores like a traditional scale. Scores are based on number of words repeated back. |
| Secondary | Trail Making Test: Trail A | Baseline | Working memory by Digit Span and Letter Number Sequencing, and attention/executive functions were measured by the Trail Making Test (Parts A and B). This is an assessment of attention/executive function, it does not have an interpret-able range of scores like a traditional scale. Subjects makes trails on paper against time. |
| Secondary | Trail Making Test: Trail A | Endpoint (12 weeks) | The Trail Making Test is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as fast as possible while still maintaining accuracy. ( Arnett, James A.; Seth S. Labovitz (1995). "Effect of physical layout in performance of the Trail Making Test". Psychological Assessment 7 (2): 220-221. doi:10.1037/1040-3590.7.2.220. Retrieved 2012-02-22.) Part A is used primarily to examine cognitive processing speed. Part B, in which the subject alternates between numbers and letters, is used to examine executive functioning.
