“…Historically, public health practice and policy have, in great part, relied upon the discipline of epidemiology, which primarily uses quantitative methods to characterize the distribution of diseases within populations, elucidate causal relationships between exposures (e.g., individual behaviors) and health outcomes, and inform the development, implementation, and evaluation of health promotion and disease prevention interventions (Goodson & Vassar, 2011;Jack, 2006). Randomized clinical trials, widely considered the gold standard and highest quality of evidence, and cost analyses are other important tools for policy makers, reflecting the ideal that scarce public resources should be invested in policies and programs that have demonstrable positive outcomes and efficacy (Bryman, 2007;Rhodes, Stimson, Moore, & Bourgois, 2010;Stenius, Makela, Miovsky, & Gabrhelik, 2004;Task Force on Community Preventive Services, 2005).…”
