Objectives : We purposed to objectify the pattern diagnosis of Tic disorders through factor and reliability analysis regarding a pattern identification questionnaire concerning Tic disorders in children. Methods : We chose and studied 144 children who were pattern-diagnosed out of 200 tic disordered children who visited H hospital in Seoul from January 2006 to April 2011. Results : 1. TTD (50%) was the most common type and the occurrence rate in male children was higher(4.76:1). Also, the rate of hospital visits was highest at the age 8(23.6%). 2. In results concering pattern diagnosis, Gan-poong-nae-dong was most frequently diagnosed in 53 patients (36.8%), and Dam-hwa-yo-sin (42 patients), Gan-sin-um-her (30 patients), and Bee-her-gan-wang (6 patients). 3. In an attempt to verify the reliability of the questionnaire, the coefficient regarding the whole questions (Cronbach ${alpha}$) came to 0.909. Moreover, the reliability coefficient foreach sub factor was 0.687 in Ganpoong-nae-dong, 0.817 in Dam-hwa-yo-sin, 0.851 in Bee-her-gan-wang, and 0.726 in Gan-sin-um-her, respectively. Thus, their consistency was ensured. 4. In exploratory factor analysis concerning the most common five questions in the questionnaire, the questions of Dam-hwa-yo-sin and Gan-poong-nae-dong appeared to be part of different factors. While, Gan-sin-um-her and Bee-her-gan-wang questions showed that they belong to the same factors. 5. In factor analysis excluding both Gan-sin-um-her and Bee-her-gan-wang questions, both showed significant results; however, the one excluding Gan-sin-um-her showed improved results. Conclusions : From the above results concerning the Pattern Identification Questionnaire for Tic Disordered children, three separated patterns of Bee-her-gan-wang, Dam-hwa-yo-sin, Gan-poong-nae-dong are thought to be available for clinical use. However, further validity studies are needed.
