PRIMARY outcome

Timeframe: Treatment Week 0 and Week 6

Population: Five subjects were unable to handle the demands of the Rapid Visual Information Processing (RVIP) test, part of the composite primary outcome measure, and did not provide valid data.

\* Composite Cognitive Primary Outcome = mean of z-scores from the Brief Assessment of Cognition in Schizophrenia (BACS) Symbol Digit test, the Hopkins Verbal Learning Test (HVLT), and the Rapid Visual Information Processing test (RVIP). Z-scores for each test were calculated as Z = (individual patient score - pooled baseline mean)/(pooled baseline standard deviation). Higher values of the composite score represent a better outcome.

SECONDARY outcome

Timeframe: Every other week for 6 weeks

Population: Safety data available for 56 participants exposed to study treatment.

The total BPRS score is calculated by adding the scores for scales #1-#18. Each scale ranges from "1=Not Present" to "7=Very Severe". Total scores range from a minimum score of 18 to a maximum score of 126. A higher total score indicates a more severe psychiatric symptom rating.

The psychosis score is calculated by adding the scores for scales #4 Conceptual Disorganization, #11 Suspiciousness, #12 Hallucinatory Behavior, and #15 Unusual Thought Content. Each scale ranges from "1=Not Present" to "7=Very Severe". The minimum psychosis score is 4 and the maximum psychosis score is 28. A higher score indicates a more severe psychosis rating.

SAS total score for extrapyramidal side effects: Frequencies of greatest within-participant increase (worsening) from pre-treatment baseline, by treatment group. Total scores calculated by adding scores from scales #1-#11. Each scale ranges from "0=None/Normal" to "4=Extreme/Severe". The minimum total score is 0 and the maximum score is 44. Higher scores indicate a more severe extrapyramidal side effect rating.

SECONDARY outcome

Timeframe: Treatment Week 0 and Week 6

Population: Role play data was collected at baseline and week 6, so only those participants who completed the role play at week 6 appear in these outcome analyses.

Participant reported responses after Brief Role Play. The Reactions to Partner item was calculated by totaling responses to 7 scales. Each scale score ranges from 1-5, which 1 being "completely agree" and 5 being "completely disagree". The minimum score for this measure is 7 and the maximum score is 35. Higher responses indicate a more negative reaction to their role play partner.

SECONDARY outcome

Timeframe: Treatment Week 0 and Week 6

Population: Role play data was collected at baseline and week 6, so only those participants who completed the role play at week 6 appear in these outcome analyses.

Participant reported responses after Brief Role Play. The Willingness to Interact item calculated by totaling scores from items 1-6. Each score ranges from 1-5, with 1 being "definitely willing" and 5 being "definitely unwilling". The minimum score for this measure is 6 and the maximum score is 30. Lower scores indicate more willingness to interact with their role play partner again in the future.
