In this presentation, Dr. Barkley presents his view on the best means for clinically evaluating ADHD in children and adolescents. The goals of the evaluation are initially discussed followed by information to be obtained before the day of the evaluation as well as topics to be covered in the initial interview with parents and children/teens. The issues to be addressed by the evaluation and the best methods for doing so are then presented. The types of rating scales and psychological tests that are useful in the evaluation of ADHD will also be reviewed. Special attention is given to the problems with using neuropsychological testing to make a diagnosis of ADHD. The presentation concludes with the topics essential to cover in the feedback conference with the parents on the results of the evaluation.
