Cultural Differences in Reactions to Tics and Tic Severity.

The present study used parent-report data to explore cross-cultural similarities and differences in tic severity and reactions to tics across 223 children with Tourette's disorder (TD) from the United States, United Kingdom, and Netherlands/Norway. Psychometric properties of the TARS-PR and PTQ were also examined and results indicated that both measures may be suitable for assessing tic severity and the consequences of tics in these countries. No differences in parent-reported tic severity were found. However, parents of children with TD from the United Kingdom reported significantly more reactions to their child's tics than parents from the United States and Netherlands/Norway.
