Publisher's Synopsis
This well–established text provides an accurate and comprehensive account of current knowledge through the rigorous and critical integration of empirical findings with clinical experience and practice. In this way it provides a coherent appraisal of the current state of the field to help clinicians in their daily work. The third edition has been completely reorganised and in many cases chapters have been divided and expanded. Overall there is a greater emphasis on clinical practice and much of the pure theory has been judiciously pruned. There are many new contributors and 21 new chapters.
