Part 3: Where does CNA apply? · Module 5
Asking a question CNA can actually answer
Which Research Questions Fit CNA?
CNA does not answer "by how much does X move coverage." It answers a sharper, more useful question: " which conditions, alone or in combination, make the difference to the outcome. " In the words of the method's own literature, CNA hunts for difference-making conditions , the necessary and/or sufficient combinations that an outcome actually depends on. Good CNA questions are always shaped that way, and the best ones point straight at a problem you can fix.
Here are five questions immunization teams genuinely ask, written the way CNA likes them:
What You Will Be Able to Do
- Write a research question in the shape CNA can answer.
- Tell a CNA question apart from a regression question.
- Spot when a question is about combinations rather than single effects.
