Observations and ratings of tics in school settings

This paper describes the findings of a school-based tic assessment procedure (direct observations, teacher rating scales) for hyperactive children with comorbid tic disorder. Rates of motor tic frequency were found to be moderately stable across both days and school settings. Correlations between direct observations of tics and clinician rating scales were generally in the low to moderate range as were correlations between teacher and clinician rating scales. Overall rates of hyperactive/disruptive behaviors were not associated with rates of motor tic occurrence, and the behavioral symptoms of both disorders were also independent for specific intervals of time.This study was supported, in part, by a research grant from the Tourette Syndrome Association, Inc., and P.H.S. grant MH 45358 from the National Institute of Mental Health. The authors wish to thank Joyce Sprafkin for providing valuable clinical services related to the conduct of the school-based medication evaluations and Joseph Schwartz for assisting with the data analyses. We are particularly indebted to the families and teachers who made this study possible.
