Which components are included in the RE-AIM framework for evaluating public health interventions?

• A. Reach, Effectiveness, Adoption, Implementation, Maintenance.
• B. Reach, Efficacy, Adoption, Intervention, Modeling.
• C. Reach, Effectiveness, Access, Implementation, Monitoring.
• D. Efficacy, Adoption, Implementation, Maintenance, Reach.

Answer: (A)

The main idea is evaluating a public health intervention across five real-world dimensions that capture both reach and sustainability. Reach looks at who the program actually gets to and whether participants reflect the target group. Effectiveness assesses the real impact on important outcomes, including practical benefits and any unintended harms. Adoption focuses on the extent to which settings and staff are willing to take up the program and representativeness of those settings. Implementation covers how faithfully the program is delivered, any necessary adaptations, and the resources required. Maintenance examines whether the effects persist over time at the individual level and whether the program continues to be used in settings after initial rollout.

This set of five terms—Reach, Effectiveness, Adoption, Implementation, Maintenance—is the one that aligns with the RE-AIM framework, which is designed to evaluate public health interventions in real-world contexts. Other choices mix in terms like Efficacy (more about ideal conditions), Intervention, Modeling, Access, or Monitoring, which aren’t components of RE-AIM and don’t fit the framework’s structure.
