Tools or questionnaires to measure screen use

Hi there,
Just wondering if there are any health professionals or researchers using questionnaires/surveys/any other tools to measure screen use in kids/young people that consider different types of screen use, content etc? There are challenges with self-reporting but also with objective measures/3rd party apps… does anyone know of good questionnaires, any ideas/thoughts at all? Just exploring options for research (screen use and health impacts). Thanks!

I saw a doc on pbs frontline ten years ago with ivy league freshman 2008 class and they all grew up in affluent families as the devices and companies came out and they have had these screens in front since birth.
