Definitions of the Elements

What does each element mean?

Reach — The absolute number, proportion, and representativeness of individuals who are willing to participate in a given initiative, intervention, or program.

Efficacy/Effectiveness — The impact of an intervention on important outcomes, including potential negative effects, quality of life, and economic outcomes.

Adoption — The absolute number, proportion, and representativeness of settings and intervention agents (people who deliver the program) who are willing to initiate a program.

Implementation — At the setting level, implementation refers to the intervention agents' fidelity to the various elements of an intervention's protocol, including consistency of delivery as intended and the time and cost of the intervention. At the individual level, implementation refers to clients’ use of the intervention strategies.

Maintenance — The extent to which a program or policy becomes institutionalized or part of the routine organizational practices and policies. Within the RE-AIM framework, maintenance also applies at the individual level. At the individual level, maintenance has been defined as the long-term effects of a program on outcomes after 6 or more months after the most recent intervention contact.
