What is a key reason for ongoing consent in longitudinal studies?

Explanation:
In longitudinal studies, researchers repeatedly interact with the same participants over time, and the study can evolve—new questions, additional data collection, or updated risks and benefits may emerge. Ongoing consent is needed so participants receive this new information, can reconsider their willingness, and can consent to any new procedures or uses of their data. This keeps consent meaningful as circumstances change, upholds autonomy, and allows participants to withdraw if they choose. That’s why the best answer is that ongoing consent enables re-information and changes to be addressed.
