The first edition, Prescriptions for Children with Learning and Adjustment Problems, was published in 1972 (Blanco) and was created to fill a specific need of school and clinical psychologists, guidance counselors, social workers, school personnel, and graduate students in those fields. It became apparent to the author that there were insufficient references dealing with intervention techniques and treatment strategies for children with mental and physical problems. Since the third edition (1988), significantly enhanced by co-author, David F. Bogacki, Ph.D., approximately 30,000 copies of the book have been sold, mainly to school and clinical psychologists, counselors, special education personnel, and graduate students. Hundreds of notes and letters sent to the authors revealed the appreciation of readers. Many have requested an expanded edition to include a greater array of prescriptions for children who are disabled, with a focus on children in preschool and who are developmentally delayed; plus, ideas for professionals in private practice. Hence, this revised fourth edition, Prescriptions for Children with Psychological and Psychiatric Problems, follows almost thirty years after the third edition. During this time, considerable changes occurred in the field. The addition of three new chapters, along with inclusion of three new co-authors that are child and adolescent psychiatrists will enhance this new, invaluable edition. Experienced psychologists know that even the best prescriptive intervention will be ineffective if the teacher, parent or primary caregiver dealing with the child who is disabled is resistant to changes or too reluctant to help the child. This book will be welcomed by child and adolescent psychiatrists, pediatricians, child neurologists, and nurse practitioners working with children, along with other handbooks and desk references in the professionalfs office today.
