Book excerpt: From leading authorities, this book presents evidence-based strategies for using multimethod assessment to enhance clinical practice. The volume is organized around key assessment targets in the areas of personality, psychopathology, and clinical management (for example, treatment planning and progress monitoring). Each chapter presents multiple methods that are particularly useful for assessing the issue at hand, provides a framework for using these methods together, and reviews the empirical data supporting their integration. Illustrative case examples clarify the approaches described and show how incorporating assessment into treatment can strengthen the therapeutic relationship.
