What does scaling up mean in health promotion?

• A. Conducting pilot tests in one community
• B. Expanding an evidence-based program to broader populations or settings
• C. Replacing evidence-based components with generic messages
• D. Reducing program scope to a single setting

Answer: (B)

Scaling up means taking an intervention that has shown positive results in one or a few settings and expanding its reach to more people and more settings, while keeping the essential components that make it work intact. It involves increasing scope—more communities, different environments, and larger populations—often with more trainers, resources, and monitoring to ensure it stays effective.

So, expanding an evidence-based program to broader populations or settings best captures this idea. It’s not about piloting in a single community, reducing scope to one setting, or replacing effective parts with generic messages, all of which would either test, shrink, or weaken what was proven to work.
