Abstract

<p>While habit reversal (HR) has been shown to be effective for treating tics, scholars in both Japan and elsewhere have noted a small number of documented cases involving severe vocal tics. In this study, we conducted behavioral therapy incorporating HR with a client experiencing severe vocal tics in the form of shouting. We then verified the effects using single-case study research methods. The client was a woman in her 40s, and she started behavioral therapy after a month of medication following hospitalization did not produce a complete response. We collected data for five hours per day over four days to establish a baseline, finding an average shouting frequency of 93.5 times per day. The intervention consisted of 15 minutes of competing reaction training with a psychologist, using throat clearing whenever shouting occurred; the client was asked to practice this training daily. The intervention was conducted 10 times over 25 days. The frequency of shouting declined considerably after the intervention, and the shouting stopped completely four weeks later, the client was then discharged. Three years after the intervention, no recurrence of symptoms has been observed. This study showed that HR was effective for severe vocal tics.</p>
