This manual is based on current neuroscience and treatment outcome studies that demonstrate the importance of focusing on the full range and depth of emotional and social functioning. Beginning with a classification of the spectrum of personality patterns and disorders found in individuals and then describing a profile of mental functioning that permits a clinician to look in detail at each of the patient's capacities, the entries include a description of the patient's symptoms with a focus on the patient's internal experiences as well as surface behaviors. Intended to expand on the DSM ( Diagnostic and Statistical Manual of Mental Disorders )and ICD ( International Statistical Classification of Diseases and Related Health Problems ) efforts in cataloging the symptoms and behaviors of mental health patients, this manual opens the door to a fuller understanding of the functioning of the mind, brain, and their development.
