Dear fellows,
I would like to open a threat that summarizes papers using measures for daily smartphone use, considering use as a "trait" (daily) rather than a "state"(mood, etc.)
Items should be like "On a regular day, how often do you check your phone" or "What app do you use most often on a daily basis"....
As this is a topic of increased importance, I thank everyone for contributing and hope we can help each other out by summarizing findings.
Cheers,
Frederic H.
