Rich with compelling case material, this hands-on workbook helps mental health practitioners and students build essential skills for clinical evaluation and differential diagnosis. Renowned diagnostician James Morrison invites the reader to interview and evaluate 26 patients with a wide spectrum of presenting complaints and ultimate diagnoses. Using multiple-choice questions and fill-in-the-blank exercises, clinicians practice the arts of interviewing and making diagnostic decisions. The convenient large-size format facilitates use. Extensive tables in the appendix provide a quick-reference guide to the interviewing techniques, diagnostic principles, and clinical diagnoses discussed in each case. See also other essential resources for new clinicians—Becoming a Therapist, Second Edition, by Suzanne Bender and Edward Messner, which covers what to say and why, starting from the very first session, and The Therapists Journey, by Robert Taibbi, which offers guidance for navigating professional development, boundaries, self-care, and more.
