- Primary Outcome Measures
Name Time Method <p>The primary outcome measure is the total tic severity score on the Dutch<br /><br>version of the Yale Global Tic Severity Scale (YGTSS). The YGTSS is a<br /><br>well-established, semi-structured clinician derived rating scale with<br /><br>satisfactory convergent and discriminant validity and interrater agreement.<br /><br>Information on tic severity is acquired for motor tics and vocal tics<br /><br>separately in five dimensions: number, frequency, intensity, complexity, and<br /><br>interference. These dimensions are summated and the subscale scores are<br /><br>obtained. A rating of impairment is added to provide a total tic severity score<br /><br>that ranges from 0 (no tics) to 55 (severe tics). </p><br>
