According to the authors, the separation between the child and adult mental health systems in Great Britain is a result both of their different histories and of professional training, which tends to be compartmentalized into either child or adult treatment. The child and adult mental health systems in the United States are separated by the same barriers but have the added burden of there being multiple sources of funding for mental health services, each with its own eligibility criteria or limitations on services covered. A valuable aspect of this book for U.S. readers is that it provides a sense of the difficulties in the interactions of the two systems even when funding is not as important an issue. The final chapter provides good guidance on various steps that need to be taken to integrate the two systems, including research, training, a focus on prevention, and ways to link the two systems.
