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

EXPERIMENTAL

The behavioral intervention group received the attention reduction intervention therapy.

Behavioral: Reducing Attentional Interventions Therapy Treatment

Control group

SHAM COMPARATOR

The control group did not receive the intervention therapy aimed at reducing attention, and subsequently was transferred to the attention reduction intervention therapy.

Other: Continue with the previous treatment plan
