Outcome Measures
Primary Outcomes (1)
Score of the Yale Comprehensive Tics Severity Scale
Three evaluation researchers who had undergone unified training and were unaware of the group assignments independently conducted blinded scoring based on the standardized protocol and the medical records provided by the same guardian of the patients. The average value was then calculated.
through study completion, an average of 6 months
Secondary Outcomes (4)
YGTSS impairment subscale
through study completion, an average of 6 months
ocular and systemic Adverse Events (AEs)
through study completion, an average of 6 months
Self-Rating Depression Scale(SDS)
through study completion, an average of 6 months
Gilles de la Tourette Syndrome-Quality of Life scale(GTS-QOL)
through study completion, an average of 6 months
Study Arms (2)
Behavioral intervention
EXPERIMENTALThe behavioral intervention group received the attention reduction intervention therapy.
Control group
SHAM COMPARATORThe control group did not receive the intervention therapy aimed at reducing attention, and subsequently was transferred to the attention reduction intervention therapy.
