Abstract

objectives
：The purpose of this study is to investigate the relationships between premonitory urge, tic severity, and comorbidities in children and adolescents with chronic tic disorders.
Methods
：In this study, scales for tic symptoms, premonitory urge, obsessive-compulsive symptoms, and ADHD symptoms were repeatedly measured twice in 26 children and adolescents aged 10 to 18 years with chronic tic disorders. Correlations between scales were confirmed through repeated measures correlation analysis, and causal relationships between scales were confirmed through regression analysis using a linear mixed model.
Results
：The degree of premonitory urges showed a significant positive correlation with the severity of tic symptoms, the severity of obsessive-compulsive symptoms, and the severity of ADHD symptoms. The ADHD symptoms showed a significant positive correlation with the severity of tic symptoms. These results were the same even in children and adolescents with tic disorders who were not diagnosed with obsessive-compulsive disorder. Additionally, premonitory urges were found to have a significant positive effect on the severity of tic symptoms.
Conclusions
：These results may be helpful in treating tic disorders and can be used in future tic disorder research considering developmental trajectory.
