This volume provides a comprehensive and in-depth handbook of qualitative research in the field of communication disorders. It introduces and illustrates the wide range of qualitative paradigms that have been used in recent years to investigate various aspects of communication disorders. The first part of the Handbook introduces in some detail the concept of qualitative research and its application to communication disorders, and describes the main qualitative research approaches. The contributions are forward-looking rather than merely giving an overview of their topic. The second part illustrates these approaches through a series of case studies of different communication disorders using qualitative methods of research. This Handbook is an essential resource for senior undergraduate and graduate students, researchers and practitioners, in communication disorders and related fields.
