CBTpro: Scaling up CBT for Psychosis Using Simulated Patients and Spoken Language Technologies

The Revised Green Paranoid Thoughts Scale (R-GPTS) is a self-report measure of paranoid thinking over the past month, consisting of two validated subscales: Subscale A: Ideas of Reference (0-32) and Subscale B: Ideas of Persecution (0-40). Items are rated from 0 ("Not at all") to 4 ("Totally"), and each subscale is scored independently by summing item responses, with higher scores indicating greater severity. Scores ≥18 on the Persecution scale indicate clinically severe paranoid ideation. This measure was only collected and reported for client participants.

The CHOICE-SF is a 12-item self-report questionnaire designed to assess perceived progress toward recovery among individuals receiving cognitive behavioral therapy for psychosis (CBTp). Each item is rated on a scale from 0 ("Not at all") to 10 ("Extremely") with the exception of the final question which is open-entry. Total scores range from 0 to 110, with higher scores reflecting greater perceived progress in psychological recovery. An increase in the CHOICE-SF score indicates improvement in recovery; a decrease suggests reduced perceived progress.This measure was only collected and reported for client participants.

The Sheehan Disability Scale (SDS) is a 3-item self-report measure that assesses functional impairment in three domains: work/school, social life, and family life/home responsibilities. Each item is rated on an 11-point scale from 0 ("Not at all impaired") to 10 ("Extremely impaired"). The total score ranges from 0 to 30, with higher scores indicating greater functional impairment. A decrease in the total score reflects improved functioning. This measure was only collected and reported for client participants.
