A vocal tic, manifested by a persistent throat-clearing cough, was treated using the habit reversal procedure which was modified to include cognitive therapy. Treatment outcome was assessed using video recordings of tic frequency and self-report measures of anxiety, tic occurrence, and associated disruption to normal living. The treatment was very effective in alleviating the tic, with improvement maintained at 6 months follow-up. These findings indicate the need for further research to establish the usefulness of targeting cognitive processes in the treatment of tic behaviour.
