The third edition of Developmental-Behavioral Pediatrics appeared in 1999 and deserves considerable attention among pediatricians, psychologists, child psychiatrists, and other specialists involved in child health care such as speech, language, physical, vocational, and occupational therapists. The book has 8 parts containing 89 chapters written by 117 authors. Under the expert editorship of 3 prominent pediatricians in developmental-behavioral pediatrics, the textbook is a link between child psychiatry and pediatrics, ie, between overt psychiatric and personality disorders and/or mental and physical disabilities interfering with age-expected functioning. Despite the contributions of numerous authors, repetition is less than 10%, and compared with the first and second editions, the textbook is shorter and more succinct. Several of the authors are new to this edition. By virtue of being a textbook, the third edition is not expected to be the "state of the art" in every chapter. Nevertheless, the scope of the textbook is impressive and covers most if not all of the issues in the field of developmental-behavioral pediatrics. The textbook is needed most in pediatrics; under the current model ofprovision of pediatric care, pediatricians are the first-line specialists confronted with the problems of development and behavior. In addition, parents still feel more comfortable addressing such problems through their pediatrician instead of through a psychologist or psychiatrist.
