Thoroughly updated and revised to emphasize the link between research and evidence-based practice, this Eighth Edition of a classic textbook presents state-of-the-art methods for conducting high-quality studies. New chapters offer guidance on developing self-report scales, conducting systematic reviews, and enhancing the integrity of qualitative studies. The ancillary Resource Manual includes application exercises, models of comprehensive research critiques, a full NINR grant application, and a "must-have" Toolkit on a CD-ROM, containing a treasure-trove of exemplary research tools (e.g., consent forms, a demographic questionnaire, statistical table templates)--all in easily-adapted Word documents to meet individual research needs. A watershed edition!
