Psychotherapists and psychoanalysts are increasingly confronted with addiction disorders in connection with depression or anxiety disorders. The inpatient treatment of addiction patients is also undergoing change and is seeking new developments and solutions. Psychoanalytic disease theory enables psychotherapists and clinicians to gain a nuanced understanding of the mental processes and structures involved in addiction disorders. The volume takes into account drive and ego psychology, self and object relation theory, and addresses the fundamental analytical disease models of developmental pathology, conflict pathology, and traumatology.
