title: Further psychometric examination of the Tourette's Disorder Scales.
abstract: The Tourette's Disorder Scales (Shytle et al., 2003) are parent- (Tourette's Disorder Scales-Parent Rated; TODS-PR) and clinician-rated (Tourette's Disorder Scales-Clinician Rated; TODS-CR) measures that assess tics, obsessions, compulsions, inattention, hyperactivity, aggression, and emotional disturbances among children with tics. Although the TODS-PR/CR are being increasingly used in clinical trials, relatively little psychometric data have been reported. Subjects were 44 children and adolescents recruited in a university tic specialty clinic. Families were administered the TODS-CR and Yale Global Tic Severity Scale. Completion of the TODS-PR and Child Behavior Checklist were counterbalanced. Results indicated adequate to excellent internal consistency for the TODS-PR/CR scores. Excellent inter-rater agreement and convergent and divergent validity was found. These results provide further psychometric support for the TODS-PR and TODS-CR.
