Following the previous post, suppose we have measured the stress level of hidden youth before the pandemic and conduct the same survey one year later and find out there is a decrease in scores. Can we say that the pandemic reduces hidden youth’s stress levels?

Thanks for the sharing!

I see. Many thanks!

That’s interesting! In my perspective, many other factors except the pandemic may affect the stress levels of hidden youth, so they need to be controlled in the tests. Otherwise, we cannot conclude that the single factor (pandemic) leads to stress reduction.
