Hi everybody!

About 6 months ago I started a data collection thought online questionnaires sent by email. I got almost 2000 people at baseline, with 60% who agreed to be contacted again for the follow-up (online questionnaire, about 10 minutes) in order to investigate associations over time.

In your mind, considering the size of the sample, the online recruitment, what should be the response rate needed I should concretely wish to get to have a "strong" dataset for my analysis?

Under which response rate I should quit the idea to use the longitudinal information?

Is there any?

I would love to hear your idea and your experience with this matter.

Thanks in advance for sharing!
