Abstract

Objectives: Comprehensive behavioral intervention for tics (CBIT) is effective in children with chronic tic disorders. This study aimed to assess the effect of group-based CBIT (group-CBIT) on tic severity and comorbid symptoms. We compared the efficacy of group CBIT with that of a control.
Methods: Thirty children with chronic tic disorder or Tourette’s disorder were enrolled in this study. Eighteen were assigned to the group-CBIT for eight sessions, and 12 were assigned to the control group. Tics and comorbid symptoms were assessed pre- and postintervention using the Yale Global Tic Severity Scale (YGTSS), Premonitory Urge for Tics Scale, attention-deficit hyperactivity disorder Rating Scale-IV, Children’s Yale-Brown Obsessive-Compulsive Scale, and the Korean-Children Behavioral Checklist. We compared the pre- and post-intervention results of each group and determined the difference in the pre- and post-intervention results between intervention and the control group.
Results: The YGTSS motor and vocal tic interference, global impairment, and global severity scores decreased in the intervention group only. Group CBIT was superior in reducing the motor tic interference, impairment score, and global severity score to the control group.
Conclusion: The group-CBIT showed an improvement in tic symptoms, especially in reducing the level of interference and impairment of tics.
