TLDR
Data from 105 subjects support the construct, convergent, and discriminant validity of the instrument, and indicate that the YGTSS is a promising instrument for the assessment of tic severity in children, adolescents and adults.Abstract:
Despite the overt nature of most motor and phonic tic phenomena, the development of valid and reliable scales to rate tic severity has been an elusive goal. The Yale Global Tic Severity Scale (YGTSS) is a new clinical rating instrument that was designed for use in studies of Tourette's syndrome and other tic disorders. The YGTSS provides an evaluation of the number, frequency, intensity, complexity, and interference of motor and phonic symptoms. Data from 105 subjects, aged 5 to 51 years, support the construct, convergent, and discriminant validity of the instrument. These results indicate that the YGTSS is a promising instrument for the assessment of tic severity in children, adolescents and adults.read more

Tourette syndrome, associated conditions and the complexities of treatment.
TL;DR: It is suggested that TS is heterogeneous from a variety of standpoints including clinical presentation and psychopathology, and thus neuropharmacological responses and possibly even aetiological and genetic mechanisms are possible.

TL;DR: A comprehensive behavioral intervention, compared with supportive therapy and education, resulted in greater improvement in symptom severity among children with Tourette and chronic tic disorder.

Course of Tic Severity in Tourette Syndrome: The First Two Decades

TL;DR: A majority of TS patients displayed a consistent time course of tic severity, which can be accurately modeled mathematically and may reflect normal neurobiological processes and assist in the identification of factors that differentially influence the course oftic severity.
