Which attribute concerns how simple the intervention is to understand?

• A. Relative advantage
• B. Observability
• C. Complexity
• D. Trialability

Answer: (C)

The main concept here is complexity—the ease or difficulty of understanding and using the intervention. Complexity assesses how much effort, learning, or steps are required for someone to adopt the intervention. When something is simple to understand and implement, it has low complexity and is more likely to be adopted quickly. If it’s hard to grasp or apply, people will hesitate or perform poorly, lowering adoption rates. In contrast, relative advantage looks at the benefits over current practice, observability at how visible the results are, and trialability at whether you can test it on a small scale.
