Designed for students and practitioners, this practical book shows how to do evidence-based research in public health. As a great deal of evidence-based practice occurs online, it focuses on how to find, use, and interpret online sources of public health information. It also includes examples of community-based participatory research and shows how to link data with community preferences and needs. Each chapter begins with specific learning objectives and concludes with practice exercises geared to the objectives. Each chapter also contains a list of key terms that are an essential part of an evidence-based public health practitioner's vocabulary. The book includes a comprehensive glossary and hundreds of online and print references, examples, and charts.
