This study examined the psychometric properties of a new measure of attention-deficit/hyperactive disorder (ADHD) symptoms , the Boatwright-Bracken Child Attention Deficit Scale (BCADS), self- and parent-report forms. Parents and children with and without ADHD completed the BCADS to determine the reliability and validity of the BCADS . The BCADS-Child and Parent had high internal consistency reliability . The total sample parent-selfratings were moderately correlated, indicating a typical level of cross informant agreement. Results indicate that the BCADS differentiates children with ADHD from children without ADHD. Children and parents in the clinical sample reported more symptoms of ADHD than those in the comparison sample. Children with and without ADHD reported fewer symptoms of ADHD than their parents. Parents' ratings on the BCADS were moderately to highly correlated with an existing measure of ADHD. Overall, the results indicate the BCADS-Child and Parent forms are internally reliable and valid measures to use when assessing ADHD.
