In RE-AIM, which dimension concerns whether an intervention is actually delivered as intended in the real world?

• A. Implementation.
• B. Reach
• C. Adoption
• D. Maintenance

Answer: (A)

Implementation focuses on delivering the intervention as planned in real-world practice. It examines fidelity to the intended protocol, the actual dose and frequency of delivery, the quality of how it is carried out, and whether the necessary training and resources are in place. Real-world settings often involve adaptations, so this dimension also considers how these changes affect whether the core components are still delivered as intended. This distinguishes it from Reach (who is exposed to the program), Adoption (which settings or staff take up the program), and Maintenance (whether it is sustained over time).
