Psychiatry has long struggled with the nature of its diagnoses. The problems raised by questions about the nature of psychiatric illness are particularly fascinating because they sit at the intersection of philosophy, empirical psychiatric/psychological research, measurement theory, historical tradition and policy. In being the only medical specialty that diagnoses and treats mental illness, psychiatry has been subject to major changes in the last 150 years. This book explores the forces that have shaped these changes and especially how substantial "internal" advances in our knowledge of the nature and causes of psychiatric illness have interacted with a plethora of external forces that have impacted on the psychiatric profession. It includes contributions from philosophers of science with an interest in psychiatry, psychiatrists and psychologists with expertise in the history of their field and historians of psychiatry. Each chapter is accompanied by an introduction and a commentary. The result is a dynamic discussion about the nature of psychiatric disorders, and a book that is compelling reading for those in the field of mental health, history of science and medicine, and philosophy.

Psychiatric and psychological practice and research is critically dependent on diagnosis. Yet the nature of psychiatric diagnosis and the rules by which disorders should be created and organized have been highly controversial for over 100 years. Unlike simple medical disorders (like infectious diseases), psychiatric disorders cannot be traced to one simple etiologic agent. The last two generations have seen major conceptual shifts in the approach to diagnosis with the rise of operationalized criteria and an emphasis on a descriptive rather than etiological approach to diagnosis. The interest in psychiatric diagnoses is particularly heightened now because both of the major psychiatric classifications in the world - DSM and ICD - are now undergoing major revisions. What makes psychiatric nosology so interesting is that it sits at the intersection of philosophy, empirical psychiatric/psychological research, measurement theory, historical tradition and policy. This makes the field fertile for a conceptual analysis. This book brings together established experts in the wide range of disciplines that have an interest in psychiatric nosology. The contributors include philosophers, psychologists, psychiatrists, historians and representatives of the efforts of DSM-III, DSM-IV and DSM-V. Some of the questions addressed include i) what is the nature of psychiatric illness? Can it be clearly defined and if so how? ii) What is the impact of facts versus values in psychiatric classification? iii) How have concepts of psychiatric diagnosis changed over time? iv) How can we best conceptualize the central idea of diagnostic validity? And v) Can psychiatric classification be a cumulative enterprise seeking improvements at each iteration of the diagnostic manual? Each individual chapter is introduced by the editors and is followed by a commentary, resulting in a dynamic discussion about the nature of psychiatric disorders. This book will be valuable for psychiatrists, psychologists and other mental health trainees and professionals with an interest in the questions and problems of psychiatric diagnosis, as well as philosophers and philosophy students interested in the problems posed by psychiatry, particularly those working in the philosophy of science.

Levels of Analysis in Psychopathology draws research from psychiatry, philosophy, and psychology to explore the variety of explanatory approaches for understanding the nature of psychiatric disorders both in practice and research. The fields of psychiatry and clinical psychology incorporates many useful explanatory approaches and this book integrates this range of perspectives and makes suggestions about how to advance etiologic theories, classification, and treatment. The editors have brought together leading thinkers who have been widely published and are well-respected in their area of expertise, including several developers of the Diagnostic and Statistical Manual of Mental Disorders and authors of the US National Institute of Mental Health's Research Domain Criteria Project (RDoC). Each main chapter has a commentary provided by one of the other authors and an introduction written by one of the editors to create an accessible, interdisciplinary dialog.

The revisions of both DSM-IV and ICD-10 have again focused the interest of the field of psychiatry and clinical psychology on the issue of nosology. This interest has been further heightened by a series of controversies associated with the development of DSM-5 including the fate of proposed revisions of the personality disorders, bereavement, and the autism spectrum. Major debate arose within the DSM process about the criteria for changing criteria, leading to the creation of first the Scientific Review Committee and then a series of other oversight committees which weighed in on the final debates on the most controversial proposed additions to DSM-5, providing important influences on the final decisions. Contained within these debates were a range of conceptual and philosophical issues. Some of these - such as the definition of mental disorder or the problems of psychiatric "epidemics" - have been with the field for a long time. Others - the concept of epistemic iteration as a framework for the introduction of nosologic change - are quite new. This book reviews issues within psychiatric nosology from clinical, historical and particularly philosophical perspectives. The book brings together a range of distinguished authors - including major psychiatric researchers, clinicians, historians and especially nosologists - including several leaders of the DSM-5 effort and the DSM Steering Committee. It also includes contributions from psychologists with a special interest in psychiatric nosology and philosophers with a wide range of orientations. The book is organized into four major sections: The first explores the nature of psychiatric illness and the way in which it is defined, including clinical and psychometric perspectives. The second section examines problems in the reification of psychiatric diagnostic criteria, the problem of psychiatric epidemics, and the nature and definition of individual symptoms. The third section explores the concept of epistemic iteration as a possible governing conceptual framework for the revision efforts for official psychiatric nosologies such as DSM and ICD and the problems of validation of psychiatric diagnoses. The book ends by exploring how we might move from the descriptive to the etiologic in psychiatric diagnoses, the nature of progress in psychiatric research, and the possible benefits of moving to a living document (or continuous improvement) model for psychiatric nosologic systems. The result is a book that captures the dynamic cross-disciplinary interactions that characterize the best work in the philosophy of psychiatry.

This multidisciplinary collection explores three key concepts underpinning psychiatry-explanation, phenomenology, and nosology - and their continuing relevance in an age of neuroimaging and genetic analysis. An introduction by Kenneth S Kendler lays out the philosophical grounding of psychiatric practice. The first section addresses the concept of explanation, from the difficulties in describing complex behaviour to the categorization of psychological and biological causality. In the second section, contributors discuss experience, including the complex and vexing issue of how self-agency and free will affect mental health. The third and final section examines the organizational difficulties in psychiatric nosology and the instability of the existing diagnostic system. Each chapter has both an introduction by the editors and a concluding comment by another of the book's contributors.
