The goal of psychotherapy as formulated in this revision of a classic text is to improve ego function of severely disturbed patients who are often hospitalized. This book shows why and how. It describes the psychotherapeutic techniques that aid patients to understand the meaning of the psychotic symbols so that they can experience reality and their emotions as separate entities. Medication effects and the neurobiology of psychotic and near psychotic patients are explained and evaluated in terms of specific ego dysfunction so that psychopharmacology may be targeted. With the first edition originally a recipient of the prestigious Heinz Hartmann Award, this valuable resource is a go-to guide for clinicians who treat patients suffering from crippling mental disorders.The Open Access version of this book, available at http: //www.taylorfrancis.com, has been made available under a Creative Commons [Attribution-Non Commercial-No Derivatives (CC-BY-ND)] 4.0 license.
