[Changes in comorbid symptoms and subjective interference in a habit reversal therapy in children with chronic tic disorder - a pilot study].

OBJECTIVE

This pilot study investigates the effects of habit reversal training in a German-speaking population of children and young adults with chronic tic disorders on comorbid symptoms and subjective interference.

METHODS

16 children were treated using a manualized program. Comorbid-symptoms (ADHD, anxiety and OCD, depression) were assessed using parent and self-ratings. Additionally, the correlation of tic symptoms with comorbid symptoms at the beginning of the therapy was analyzed.

RESULTS

We obtained positive results in reducing comorbid symptoms during a primary treatment of tic symptoms. We further found a correlation of tic symptoms and comorbid symptoms especially in parent ratings.

CONCLUSIONS

These first findings show that a primary treatment of tics may be indicated in patients with comorbid symptoms, because a therapy of tic symptoms has also positive effects on comorbid symptoms.
