Understanding Evidence, Part 1: Best Available Research Evidence
This resource enables researchers, practitioners, and policymakers to determine whether or not a prevention program, practice, or policy is actually achieving the outcomes it aims to and in the way it intends. The more rigorous a study's research design, (e.g., randomized control trials, quasi-experimental designs), the more compelling the research evidence.
