Relations Between Tic Severity, Emotion Regulation, and Social Outcomes in Youth with Tourette Syndrome.

This study examined associations between tic severity, emotion regulation, social functioning, and social impairment in youth with Tourette Syndrome (TS). Emotion regulation was examined as a mediator between tic severity and social outcomes. Seventy-seven caregivers of youth with TS (M age = 13.1 years; SD = 2.29) were administered proxy-report measures of tic severity, emotion regulation, social functioning, and social impairment. Total and motor tic severity were negatively associated with emotion regulation and social functioning, and positively associated with social impairment (r's = 0.23 to 0.43). Vocal tic severity was not related to emotion regulation or social functioning, but was positively associated with social impairment (r = 0.36). Emotion regulation mediated the relations between total tic severity and both social outcomes, and motor tic severity and both social outcomes. Interventions that target emotion regulation would likely be a beneficial adjunctive therapy for youth with TS, and may result in improved social outcomes.
