- QUOTE: Randomized field trials (RFTs) provide a powerful means of testing a defined intervention under realistic conditions. Just as important as the empirical evidence of overall impact that a trial provides (Flay et al., 2005), an RFT can also refine and extend both etiologic theory and intervention theory. Etiologic theory examines the role of risk and protective factors in prevention, and an RFT formally tests whether changes in these hypothesized factors lead to the prevention of targeted outcomes. Theories of intervention characterize how change in risk or protective factors impact immediate and distal targets and how specific theory driven mediators produce such changes (Kellam and Rebok, 1992; Kellam et al., 1999). The elaborations in theory that can come from an RFT draw on understanding the interactive effects of individual level variation in response over time to different environmental influences. An adolescent drug abuse prevention program that addresses perceived norms, for example, may differentially affect those already using substances compared to nonusers. ...
