Thoroughly revised to emphasize the link between research and evidence-based practice, this Eighth Edition presents methods and tools for generating and assessing evidence for nursing practice. This edition offers more guidance on evaluating and critiquing research evidence. Other revisions include more in-depth coverage of both qualitative and quantitative research and a new chapter on developing and testing new instruments. Note: The for-sale Student Resource guide to accompany the text is now fully revised to meet emerging graduate course needs. New features include a free CD-ROM called the "Toolkit," which includes copious application exercises, samples of systematic reviews, and full critiques of two of the eight studies in the text. Please note that this is sold separately: Student Resource Manual with Toolkit, ISBN: 978-0-7817-7052-1.
