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.

We 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

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.

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

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.

We applied mixture modeling of response times to existing experimental ESM data & found that higher sampling frequencies led to more careless responding, while longer questionnaires did not. Co-led by Esther Ulitzsch. Accepted at Psychol Assess, preprint: doi.org/10.31234/osf.io/2s38a_v1
