The same cannot be said of the book’s sections on behavioral interventions. These are tacked on to the end of the text and not integrated into the issue of comorbidity. However, behavior management procedures are well described and informative. Unfortunately, the nonspecialist will be misled by the book’s claims of efficacy. The authors report that there is ample evidence that behavioral intervention is effective in ADHD, but they do not substantiate this claim and provide no relevant references. This section stands in marked contrast to the rest of the book, which is meticulous in this regard. The book was published at a time when the results of the large multisite study of medication alone, behavior treatment alone, and medication and behavior treatment in combination with medication (1) were known. This study failed to document an advantage for the combination treatment over medication alone and did not support the efficacy of extended, intense, systematic multimodal behavioral treatment in children with ADHD. There is no mention of the trial in the book. It is unfortunate that standards for scholarship and clinical relevance that were applied to the sections on diagnosis, pharmacotherapy, and family history were not applied to the coverage of behavioral management. In every other respect, the book is a wonderful resource to anyone interested in what is known about ADHD.
