This innovative volume brings together two important literatures for the first time. One concerns the role of quality assessments in social policy, especially health policy. The second concerns ethical and social issues raised by prenatal testing for disability. A theme of this literature has been the role played by controversial assumptions about the quality of life of people with disabilities. Hitherto, these two literatures have had little contact with each other: few scholars have written about both, or have compared the two domains in a systematic way, while people with disabilities and disability scholars are underrepresented in recent discussion on health policy and quality of assessment. This book turns the perspectives of disability scholars on issues that have largely been the province of health methodology, policy and philosophy, while angling philosophical policy analysis on problems that have largely been the province of disability scholarship. This volume will be sought after by bioethicists, philosophers, and specialists in disability studies and healthcare economics.
