I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...
🚨 Publication alert (CHBR): Together with colleagues from the University of Navarra, I investigated what role the quality of mobile media use (gratification and situation variety) plays when measured alongside screen time. Result: quality may be more important than quantity. doi.org/10.1016/j.ch...

Time to share some news I've been sitting on: starting in January, I will lead a @dfg.de Emmy Noether Group at @weizenbauminstitut.bsky.social! We will investigate how local public spheres are constituted under conditions of digitalization & globalization. www.weizenbaum-institut.de/en/research/...

🚨 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. doi.org/10.31235/osf...

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. 📱 journals.sagepub.com/doi/10.1177/...
🚨 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...

To investigate media effects, do we have to think more clearly about time ⌚? Our new publication in the 🎉*Journal of Communication*🎉 investigates how our conceptualizations of time can affect our conclusions: doi.org/10.1093/joc/... (1/6)
Possible futures all at once: time frame and time lag in short-term longitudinal media effects research on well-being
Abstract. When assessing media effects, we seldom consider how they change over time. Especially with the prevalence of smartphone use as short-lived, frag

Quant people: Do you know any way to perform Multilevel SEM with 3 levels and random intercepts and slopes in R? I know lavaan doesn‘t support this (yet) and I try to avoid getting Mplus just for this…
