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...

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/...

🚨🎉 Happy to announce a new publication in @DiePublizistik where I present an app combining three data collection methods. In the short paper, I explain its relevance for the social sciences, its functionality, and its future development. Give it a read! doi.org/10.1007/s11616-023-00788-6

One App to Assess Them All - Publizistik
Smartphones have become popular tools for data collection in the social sciences due to their high prevalence and mobility. Surveys, experience sampling (ESM) and tracking/logging are among the most used smartphone data-collection methods. However, existing apps are either commercial solutions, require programming skills, collect sensitive data, or do not handle all three methods simultaneously. When two or more data collection methods are used simultaneously, it further burdens both researchers and participants. This paper introduces the app MART (Mobile Assessment Research Tool) that solves these problems and is available for Android and iOS devices. Content and data collection settings can be customized dynamically via a web interface without the need to compile a new version of the app when changes are made. While the logging functionality is only supported on Android devices, data donation via the app Screen Time is requested on iOS devices. MART is already functional, and the source code is open-source and available on GitHub. The necessary long-term revisions for its use in custom projects without reprogramming are currently under development.
