title: Further psychometric properties of the Tourette's Disorder Scale-Parent Rated version (TODS-PR).
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.
