- The first preprint from my PhD is out: osf.io/preprints/ps...! 🥳 We explored the temporal dynamics of four careless responding indicators (response time, within-beep standard deviation, an inconsistency index, occasion-person correlation) in ESM data across different samples. Thread below🧵
- Aaand it's published! 🤩 doi.org/10.1177/1073...
- The first preprint from the SHARE study is out! 🥳 We compared the effects of three different incentives (a bulk payment, a bulk payment with personalized feedback, and payment per beep) on data quantity, data quality, and participant experiences in a student sample.
- The effect of incentive type on data quality and quantity in an experience sampling study in a student population: osf.io/pc924
- We found that paying participants per beep increases compliance as compared to bulk payment with or without personalized feedback—and without harming data quality. Interestingly, we found no significant effects for personalized feedback on data quantity, data quality, or participant experiences.
- In the absence of any significant effects on data quality and participant experiences, we discuss other factors—at the beep (e.g., social context), person (e.g., clinical symptoms), and study (e.g., gamification) level—that might influence these outcomes in ESM research.

- Reposted by Milla PihlajamäkiWe built the openESM database: ▶️60 openly available experience sampling datasets (16K+ participants, 740K+ obs.) in one place ▶️Harmonized (meta-)data, fully open-source software ▶️Filter & search all data, simply download via R/Python Find out more: 🌐 openesmdata.org 📝 doi.org/10.31234/osf...
- Had a great time at the ESM Expert Network Meeting in Rotterdam! I presented the first SHARE study results: we found that paying participants per beep boosts compliance as compared to bulk payment (with or without personalised feedback)—and without harming data quality.

- Stay tuned for the preprint!
- Reposted by Milla Pihlajamäki👀Blogpost on measurement👀 I would have rather concluded that we don't really need factor analysis and can just rely on vibes (or previous literature). But here we are: "Factor analysis: Overrated, Misused, But Still Useful." 1/4
- 📣 New blog post! 📣 @ccp-kuleuven.bsky.social's @benjaminkunc.bsky.social gets into the nitty-gritty of factor analysis and its use and misuse: esmitemrepositoryinfo.com/blog-posts #Measurement #ExperienceSamplingMethod
