This volume examines the way in which disturbances in Self functions (such as identity-feelings, self-esteem, individuation and agency) may underlie the familiar neurotic disorders of depression, anxiety, obsessions, phobias and psychosomatic malfunctions (as well as certain personality traits and defects). The contributors, drawn from the United States of America, Britain, West Germany and Switzerland, discuss aspects of individuation, self-perception and self-esteem from psychodynamic, cognitive behavioural and cybernetic viewpoints. The case material is taken from a variety of therapeutic settings and is presented to illustrate therapeutic techniques and outcome studies. The empirical investigations reported involve a variety of research and psychometric methods, and the emphasis throughout is on a constructive rapprochement between different theoretical and practical approaches to the psychology of the self and its problems. The book will be of particular value to clinical psychologists, psychiatrists, social workers and family therapists.
