A school-based application of modified habit reversal for Tourette syndrome via a translator: a case study.

A school-based modified habit reversal intervention was utilized with an adolescent diagnosed with Tourette syndrome who recently immigrated from Mexico. Because the student possessed little proficiency of the English language, an interpreter was needed to help implement the procedure. The frequency of motor tics markedly decreased from baseline to intervention across classroom settings. Results of two follow-up phases revealed that motor tic levels remained below those observed in the baseline phase. Implications and limitations of these findings are noted.
