Preliminary evaluation of child self-rating using the Child Tourette Syndrome Impairment Scale.
To evaluate and compare how children with Tourette syndrome and parents rate tic and non-tic behavioral related impairment in home, school, and social domains; to compare these with clinician tic ratings; and to identify factors that may predict greater impairment.



In a sample of 85 Tourette syndrome and 92 healthy control families, the Child Tourette Syndrome Impairment Scale, designed for parent-report and which includes 37 items rated for tic and non-tic impairment, was administered to parents and, with the referent modified, to children ages 9 to 17 years. Tic severity was rated using the Yale Global Tic Severity Scale (YGTSS). Analyses utilized descriptive and multivariate statistics.



Tourette syndrome children's and parents' impairment ratings were higher than HC (p<0.001) and correlated moderately (r=0.46 to 0.54; p<0.001). Children's and parents' tic impairment ratings correlated with YGTSS (r=0.36 to 0.37; p<0.001). Parents' average ratings were higher than children's for 19 tic and all 37 non-tic impairment items. For 29 items, children self-rated impairment higher for tics than non-tics. Diagnoses of attention-deficit-hyperactivity disorder and obsessive-compulsive disorder had larger effects on parent impairment ratings.



The Child Tourette Syndrome Impairment Scale appears informative for child self-rating in Tourette syndrome.
