🚨 Preprint alert: Do 1) smartphone event log data access and 2) the Experience Sampling Method cause reactivity effects in studies? @dougaparry.bsky.social, @klingelhoefer.bsky.social, and I investigated this very question using data from 815 German Android users.

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?
