The paper presents results of preliminary work in developing a scale to assess attention deficit disorder in a manner that provides educationally useful information. Based in part on B. Keogh and J. Margolis's component analysis of attending skills in learning disabled children (skills of coming to attention, sustaining attention, and making decisions and including educationally important behaviors such as impulsivity and auditory attending), the scale's preliminary version showed adequate interrater reliability and modest relation to observational criteria. The initial study involved two teachers rating 17 children in classes for the learning disabled. Results indicate the scale's potential usefulness in assessing attention deficit disorder if it can be further developed to provide greater validity in assessing target behavior areas. (Author/CL)
