Much has been learned about effective prevention, including specific approaches that have been scientifically validated as well as broader principles for ensuring that their implementation is effective. What is most important, therefore, is for practitioners to make use of the knowledge that is already available. Many prevention efforts are not based on proven theories and good science and their implementation is not consistent with best practice. Good prevention is applied science and is labor intensive, requiring careful planning, extensive collaboration, expert consultation to address barriers, and the tailoring of the chosen approach to a specific community or setting. It is hoped therefore, that this thought piece will aid prevention practitioners in applying what is currently known regarding what works and how to implement it.
