Which statement best reflects RE-AIM and its use?

• A. Reach, Effectiveness, Adoption, Implementation, Maintenance; used to evaluate public health interventions.
• B. Randomization, Engagement, Access, Impact, Management; used to design trials.
• C. Reach, Efficiency, Accessibility, Innovation, Monitoring; used to allocate resources.
• D. Responsiveness, Equity, Applicability, Impact, Maintenance; used to assess policy.

Answer: (A)

RE-AIM is a framework for evaluating how well public health interventions work in real-world settings. It looks at five dimensions to capture both impact and practical feasibility: Reach, Effectiveness, Adoption, Implementation, and Maintenance. Reach considers who participates and how representative they are of the target population. Effectiveness looks at the actual outcomes produced, including benefits and potential harms. Adoption examines how many and what kinds of settings or providers take up the intervention. Implementation focuses on how faithfully and efficiently the intervention is delivered in practice, including resources used and fidelity to the program. Maintenance assesses whether effects persist over time at both the individual and setting levels, and whether the program becomes a sustained part of routine practice.

This description matches the statement that explicitly names those five dimensions and states they are used to evaluate public health interventions. The other options mix in terms from other domains—such as randomization from trial design or terms like efficiency, accessibility, or monitoring—that don’t line up with RE-AIM’s components, and thus don’t reflect the same framework or its purpose.
