Chronic tic disorder (CTD) may have a huge impact on life quality. Habit Reversal Training (HRT) and Exposure Response Prevention (ERP) are effective therapeutic modalities. This study examined the effect of a combined treatment using both HRT and ERP in children and adolescents with CTD. The treatment outcome was examined as an individual treatment compared to a group setting. There was no control group. The study examined both acute outcome and outcome at one year of follow-up. Predictive factors for treatment outcome were evaluated.
