Book excerpt: First published in 1998, this volume examines a major function of research which is to strengthen the knowledge base of health professions and so enhance patient care. The rapid growth has unfortunately led to it being seen by many as an elitist activity full of jargon, carried out by academics. This to some degree has led to a theory practice gap with some professionals not recognising their important role within the research process. It is important to dispel the myth that all practitioner should carry out research, though they should use elements of the research process to develop a questioning and evaluative approach to care. This book will enable reader to demystify and enhance their understanding of terminology used in research and contains almost 300 terms. It offers readers a unique approach to explanations for each term by offering its Everyday use; its Research use; an Example and Related terms.
