PREFACE

Essentials of Nursing Research, ninth edition, helps students learn how to read and critique research reports and to develop an appreciation of research as a path to enhancing nursing practice.

We continue to enjoy updating this book with important innovations in research methods and with nurse researchers’ use of emerging methods. Feedback from our loyal adopters has inspired several important changes to the content and organization. We are convinced that these revisions introduce important improvements—while retaining many features that have made this book a classic best-selling textbook throughout the world. The ninth edition of this book, its study guide, and its online resources will make it easier and more satisfying for nurses to pursue a professional pathway that incorporates thoughtful appraisals of evidence.

LEGACY OF ESSENTIALS OF NURSING RESEARCH This edition, like its predecessors, is focused on the art—and science—of research critique. The textbook offers guidance to students who are learning to appraise research reports and use research findings in practice.

Among the basic principles that helped to shape this and earlier editions of this book are as follows:

1. An assumption that competence in doing and appraising research is critical to the nursing profession

2. A conviction that research inquiry is intellectually and professionally rewarding to nurses

3. An unswerving belief that learning about research methods need be neither intimidating nor dull

Consistent with these principles, we have tried to present research fundamentals in a way that both facilitates understanding and arouses curiosity and interest.
