Following in the tradition of its previous editions, the updated and fully revised fifth edition of this classic guide to grant writing is especially written for health and human service professionals. It provides a comprehensive, systematic, and easy-to-follow stepwise guide to writing competitive grant proposals for research, education, innovative practices, and demonstration projects. Never has the need to advance evidence to improve the health of the public been greater. Generating evidence requires funding, and grant writing has become an essential activity for every health and human service professional who must seek funds to advance innovative research, education, and practice initiatives. Uniquely focused on developing grant-writing skills as part of a professional’s career, this one-of-a-kind guide addresses the full range of essential competencies needed to ensure success. The new edition expands coverage on how to compose an effective aims page, explains how to write a compelling literature review to support significance of a proposal, and describes considerations for specific types of study designs. Additionally, the guide provides a more extensive discussion of mentorship, plus tips for predoctoral students and postdoctoral fellows.
