This authoritative clinical reference and text--now revised and updated with 50% new content--presents the assessment tools and strategies that every evidence-based psychotherapy practitioner needs. Unlike most assessment texts, the volume is organized around specific clinical problems. It explains how to select and use the best measures to assess clients' symptoms, generate diagnoses, plan appropriate treatments, and monitor progress. Clinician- and student-friendly features include tables comparing and contrasting relevant measures, sample forms, and case examples. Every chapter addresses considerations for primary and managed care settings.
