Currently, the Yale Generalized Tic Severity Scale (YGTSS) is mainly used at home and abroad to assess the condition of children. The three parts of the Yale Grading Scale score motor tics and vocal tics separately, and the severity of tics is graded from 0 to 5 mainly in terms of quantity, frequency, intensity, complexity and interference. Motor and vocal tics are scored separately up to a maximum of 25 points, and the total tic score obtained by adding the two together is up to a maximum of 50 points, reflecting the severity of the motor and vocal tic symptoms themselves. The third component is the Overall Impairment Scale, which is also scored on a scale of 0 to 5 and also has a total score of 50. This score reflects the degree of overall impairment caused by the child’s exposure to the various stressors caused by the tics and integrates the degree of difficulty associated with the tics in terms of the child’s self-esteem, family life, social relationships, and performance at school or work.
