What is the primary purpose of assessing implementation fidelity before judging an intervention's effectiveness?

• A. To speed up publication
• B. To ensure the intervention was delivered as intended
• C. To blame staff performance
• D. To bypass training

Answer: (B)

The main idea is to confirm that the intervention was delivered exactly as it was designed before interpreting the results. When you assess fidelity, you’re checking whether the core components were implemented as intended, how much of the program participants received (dosage), the quality of delivery, and how engaged participants were. This matters because outcomes can be influenced by how the program was implemented, not just by the program itself. If fidelity is high and outcomes are positive, you gain a clearer claim that the intervention works. If fidelity is low, poor results might reflect delivery issues rather than the intervention’s true effectiveness, signaling a need for better training or adjustments to how the program is carried out. The other options—speeding up publication, blaming staff, or bypassing training—do not address the accuracy of attributing outcomes to the intervention itself.
