From Screen Time to Daily Rhythms: A Mixed Methods Study of Smartphone Use Among German Adults
| Journal of Quantitative Description: Digital Media
doi.org
🚨 Publication alert (JQD:DM): @dougaparry.bsky.social , @mjemmer.bsky.social , and I investigated the daily times, gratifications, and locations of, and activities alongside smartphone and app use in Germany using a combination of surveys, MESM, logging, and data donations 📱. doi.org/10.51685/jqd...

How often is too often in ESM research?
🚨New study out!
We compared 6 beeps/day vs. 12 beeps in 2 h bursts.
Both work, but burst designs show more fatigue + attrition — still useful if high temporal precision matters.
App onboarding, though? Big bias alert. 📱

🚀 The GESIS AppKit is live! 🚀
Three years ago we started the project of providing "an App" for Social Scientists @gesis.org . Today, it is much more than that. It is a management system for mobile, intensive-longitudinal studies. Interested?
