With this resource, speech-language pathologists (SLPs) and audiologists will learn to apply best evidence as they make critical decisions about the care of each individual they serve. The first to cover this important topic for the field of communication disorders, this book introduces SLPs to the principles and process of evidence-based practice, thoroughly covering its three primary components: external evidence from systematic research, internal evidence from clinical practice, and evidence concerning patient preferences. Developed by Christine A. Dollaghan, a researcher in the field of language acquisition and disorders, this book makes complex concepts understandable with its clear, reader-friendly language; vivid step-by-step examples of key processes; and illuminating figures and tables. Readers will come away with a solid, practical understanding of evidence-based practice - knowledge they'll use throughout their careers to make sound clinical decisions about the screening, diagnosis, and treatment of communication disorders.
