The second section comprises the bulk of the book—14 of 25 chapters—and is devoted to an in-depth analysis of outcome measurement strategies and instruments organized by patient characteristics, including age and diagnosis. Each of these chapters provides a relatively exhaustive inventory and review of a range of scales, instruments, and measures specific to the particular patient focus. However, because each chapter is written by a different group of authors, all the chapters have a somewhat different structure, style, and analysis. Each chapter is authoritative and well referenced. And although each one is thorough, ready comparison from chapter to chapter is not easy; the book might have been more useful had each chapter followed a set outline or format.
