Seventy-five percent of eligible participants participated in adulthood follow-up interview. Participants and non-participants in adulthood follow-up assessment did not differ significantly in any demographic characteristics at baseline. Children who did not participate in neuropsychological testing at childhood baseline had a lower rate of comorbid tic disorders than those children who participated (χ2=5.2, df=1, p=0.02).
