Design outcomes

Primary

MeasureTime frameDescription
Yale Global Tic Severity Scale (YGTSS)From Baseline to 4, 8, and 12 Weeks AssessedThe YGTSS scale refers to Yale Global Tic Severity Scale, and it is a rating tool used to gauge the course of Tourette's syndrome in patients.

Secondary

MeasureTime frameDescription
Beck Youth Inventories (BYI-II)From Baseline to 12 Weeks AssessedThe new Beck Youth Inventories™ Second Edition (BYI-2) uses five self-report inventories to assess symptoms of depression, anxiety, anger, disruptive behavior, and self-concept in children and adolescents.

Child Behavior Checklist (CBCL)From Baseline to 12 Weeks AssessedThe Child Behavior Checklist (CBCL) is a widely used caregiver report form identifying problem behavior in children. It is widely used in both research and clinical practice with youths.
Autism Behavior Checklist-Taiwan Version (ABCT)From Baseline to 12 Weeks AssessedThe Autism Behavior Checklist (ABC) is one component of the Autism Screening Instrument for Educational Planning (ASIEP) and is the only one that has been evaluated psychometrically.

Clinical Global Impression Scale (CGI)From Baseline to 4, 8 and 12 Weeks AssessedClinical Global Impression Scale (CGI) severity item provided with a seven-point scale of severity of the patient's clinical condition (1=normal, not at all ill; 2=borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients).
Visual Analogue Scale for GI symptoms (VAS-GI)From Baseline to 12 Weeks AssessedVisual Analogue Scale for GI symptoms, VAS-GI (visual analogue scale, VAS 0-10) was designed to measure the response of symptoms and well-being in patients after taking PS128.
miRNAFrom Baseline to 12 Weeks Assessedperipheral blood miRNA expressions
