Abstract: AbstractObjectiveTo introduce Yale Globle Tic Severity Scale( YGTSS )and evaluate its efficacy and reliability. MethodsThe scale was translated into Chinese with the effort to keep its original literal meaning.From July 2001 to June 2002,72 cases of tic children were evaluated with YGTSS：their total scores were compared with disease severity reflected by their ICD10 classification;the clinical efficacy was also evaluated through comparing their score increment after treatment and the subjective judgement on the clinical improvement by the patents.In Another 24 patients,5 dimensional scores (number,frequency,intensity,complexity and interference) of both movement and vocal tics were recorded.Together with their total scores,the interobserver reliability of the scale was evaluated. ResultsThe total scores of tic children were found to be consistent with the ICD10 Classification and the score increment correlated well with the clinical improvement(F=59.31 and 124.44,respectively,P<0.01).The intraclass correlation coefficient( ICC ) of 5 dimensional scores of movement and vocal tics as well as the total scores were all greater than 0.7,indicating the excellent interobserver consistency of the scale. ConclusionThe Chinese version of YGTSS shows good efficiency and reliability,hence should be a useful method in evaluating tic severity.
