One of the key challenges of all types of practice and research is finding a way to measure a given problem. The seminal Measures for Clinical Practice and Research two-volume set contains hundreds of the most useful measurement tools–alongside the authors’ guidance on how to select and score them–for use in clinical practice and in research. While the first volume focuses on measures for use with couples, families, and children, the second volume focuses on measures for use with adults whose conditions of concerns are not focused on family relationships or couple relationships. Both include an introduction to the basic priniciples of measurement, an overview of different types of measures, and an overview of Rapid Assessment Instruments. The texts also contain descriptions and reviews of each instrument and information on how they were selected. Each classic compendium serves as a powerful tool that clinicians and researchers alike will find to be an invaluable addition to–or update of–their libraries.
