Our recovery planmakes the largest investment ever in preventive care, because that is one of the best ways to keep our people healthy and our costs under control. – President Obama, Speech to Joint Sessions of Congress, February 24, 2009 Since the first edition of Prevention is Primary was published in 2007, the notion of prevention has gained greater prominence on a national level, particularly since the Obama administration came into office. The second edition will be updated to include advances in the field of prevention while contextualizing the practice of prevention in the current economic and healthcare climate. Stronger links will be made throughout the text of the connection between various topics (for example, links between violence prevention and physical activity promotion, between mental health and violence, etc.) The second edition will retain the same organization as the first. However, two chapters will be replaced with new chapters on preventing mental health problems and addressing negative influences on the public’s health. Additional textboxes will be added to contextualize chapter content and provide real world examples and application of key concepts. Learning objectives, key terms, and review questions will be added to each chapter. An Instructors Manual will be available for download.
