What is the plan for evaluating the intervention’s effectiveness?

• A. Plan for evaluating effectiveness
• B. Ignore formal evaluation
• C. Evaluate only after intervention ends
• D. Rely solely on subjective impressions

Answer: (A)

The main idea being tested is having a clear plan for measuring whether the intervention works. You need to specify how progress will be determined using objective data, including what you’ll measure, how often you’ll collect data, and what criteria will signal success or a need to adjust the approach. This keeps decisions data-driven rather than based on feelings or after-the-fact impressions. By outlining exact procedures for evaluation, you can monitor progress in real time, determine if the intervention is producing the desired outcomes, and make timely changes if needed. Relying on impressions or waiting until the intervention ends to assess effectiveness leaves you with no early warning if the plan isn’t working, and it makes it hard to know what to tweak. So, establishing a plan for evaluating effectiveness is essential to guide ongoing decisions and ensure the intervention actually improves the target behavior.
