Diagnosis and Treatment of Mental Disorders Across the Lifespan is both a clinical diagnostic training manual for graduate level students and an essential reference for experienced mental health professionals. It provides all of the essentials of clinical practice, including placement, interviewing, crisis intervention, and diagnosis, treatment, and clinical management of specific disorders. Divided into 2 sections, the first part of the text presents the foundation of clinical skill development and the second part emphasizes the application of those skills as they relate to specific client problems. Information is presented at both basic and advanced levels, making this text valuable for both novices and seasoned clinicians. Unlike other texts, this book takes a lifespan approach to psychopathology, including information on etiology, clinical presentation, diagnosis, and treatment of a wide range of DSM disorders that occur in people of all ages.
