abstract
This study evaluated the psychometric properties of the Tourette’s Disorder Scale-Parent Rated (TODS-PR), a 15-item parent-rated instrument that assesses a range of common symptoms seen in childhood Tourette’s Disorder (TD) patients including tics, obsessions, compulsions, inattention, hyperactivity, aggression, and emotional disturbances. Participants were 67 children and adolescents ages 6–17 years who were diagnosed with TD and/or OCD and seen as a part of a larger study. Confirmatory factor analyses supported the original 4-factor structure of the TODS-PR with some slight re-specification of factor content. Internal consistencies were acceptable for the TODS-PR Total Score and factors. The TODS-PR Total Score and factors showed good convergent validity with other measures of symptomatology and impairment. These findings suggest that the TODS-PR is a reliable and valid parent-rating scale for assessing TD symptoms
