A school-based intervention designed to reduce the frequency of tics in children with Tourette's Syndrome

The study used an A/B/B+C multiple baseline design across individuals with a follow up to examine the effects of a two-component treatment package com posed of habit reversal and self-modeling to reduce the frequency of ties i n 4 school-age students diagnosed with Tourette's Syndrome. The students we re taught competing responses to their multiple ties. Subsequently, they vi ewed themselves on three 5-minute edited videotapes displaying non-tie beha viors. Three of the 4 students showed substantial decreases in their ties, which were maintained during a 5- to 10-week follow up. The fourth student showed only mild decreases in ties.
