The book consists of 15 chapters grouped into five parts. In general, the chapters do not follow a uniform, coherent structure. One might have hoped that the editors would have requested of the authors to foreshadow the core issues in their respective areas. Instead, there is an admixture of chapters that are purely theoretical and conceptual and of those that report on a single study with little literature overview. The link between some chapters and considerations of changes in DSM-5 are uncertain. Authors von Korff, Andrews, and Delves provide a nice summary of research on the World Health Organization Disability Assessment Schedule, but the competing proposals to address this issue are not described, and where this assessment schedule fits in DSM-5 is not mentioned. The suggested modifications for personality disorder classification have, perhaps, received the most critical comment. Yet, the single chapter in this book that is focused on axis II disorders is a research report of a single study. To be sure, it is an erudite, high-quality piece of work. But it does not offer an evolutionary perspective.
