✨ We are closing the year with fantastic news! ✨ Prof. Dr. @inezgermeys.bsky.social, Prof. Dr. @ginettelafit.bsky.social and Prof. Dr. Ruud van Winkel have been awarded a KU Leuven Methusalem grant for the project: “A New Era in Psychosis Treatment: Digital Interventions for Negative Symptoms”

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.

A new publication from my PhD project on model selection for nonstationary time-series data is out, co-authored with an amazing team (Anja Franziska Ernst, @ginettelafit.bsky.social , Ward B. Eiling, @bringmannlaura.bsky.social)! Link: doi.org/10.1111/bmsp...

Check the preprint below, @benjaminkunc.bsky.social analyzed the structure of social experiences in daily life using ESM

Save the date for the 2026 REAL ESM/EMA Workshop!

Check new preprint: Systematic review of choices in ESM research across many stages of the research workflow.

Thoughtful piece about the influx of suspicious #preprints (some involving AI) to PsyArXiv & other preprint servers. Wee mention of me and some of the preprint monitoring I've been doing in collaboration with PsyArXiv. Servers are not going to take this lying down. #OpenScience

📢New vacancy for a PhD Position: Co-Orchestration of Collaborative Learning in Synchronous Hybrid Education. Join Annelies Raes and me on a project that investigates how collaborative learning can be supported in synchronous hybrid education. More information here: www.kuleuven.be/personeel/jo...

📢 New paper alert! Invited review led by Francis Tuerlinckx for BJMSP on the latest developments in #EMA / #ESM research 📱🔍 doi-org.kuleuven.e-bronnen.be/10.1111/bmsp... A (very) short 🧵 below: @saa2025leuven.bsky.social

Save the date: #SAA2026 will take place on 3-5 August 226 in Vienna 🇦🇹. We will be hosted by @lauramkoenig.bsky.social @alearuf.bsky.social @univie.ac.at

What amazing three days at #SAA2025 new knowledge, new research ideas, and a lot of fun. Thanks a lot for all the people who collaborated and help with the organisation @saa2025leuven.bsky.social

Happening now at #SAA2025! @gudruneisele.bsky.social leading a symposium on ESM data quality & quantity. Kicking us off @ccp-kuleuven.bsky.social PhD student, @millapihlajamaki.bsky.social on careless responding. Preprint: osf.io/preprints/ps... #ProudSupervisor

International students upend their lives to join American science, bringing their novel insights that drive innovation. Now, they are being illegally targeted by Trump, because Harvard won't back down. Classic bully behavior. We Stand Up for International Students. www.npr.org/2025/05/22/n...

Just a reminder that the Open Science for ESM workshop by Prof. Olivia J. Kirtley and Prof. Ginette Lafit is also taking place on Friday, May 30th! @oliviajkirtley.bsky.social @ginettelafit.bsky.social More info and registration here: gbiomed.kuleuven.be/english/rese...

Come and join @ginettelafit.bsky.social and I in Leuven after SAA to learn about #OpenScience for Experience Sampling/Ecological Momentary Assessment! More details in the post below. Please share! @ambulatory-assessment.org

On May 29 @oliviajkirtley.bsky.social and I are organising a workshop on #OpenScience for ESM research. Check the link below for more information

Are you doing EMA research and wonder how to go about it? In recent work we've adressed some open questions and challenges, here is a brief summary of papers and materials. 🧵 #PsychSciSky 🧪 #StatsSky

In this new preprint @yongzhangzzz.bsky.social investigates how to assess the quality of estimated VAR-based person specific temporal questions with respect to the number of time points.

Check this new preprint by @millapihlajamaki.bsky.social introducing an investigation on the temporal dynamics of careless responding in ESM across different samples

📣 This is a friendly reminder to submit your abstract(s) for the Society for Ambulatory Assessment (SAA) conference! -www.saa2025.com 🙌

8b. Power for your most power-hungry hypothesis-analysis (yes, they are an inseparable pair), not your least.

today I became that reviewer that submits the wrong reviews 😅

Great new AMPPS @psychscience.bsky.social paper on preprocessing Experience Sampling Method #ESM data by Jordan Revol, Eva Ceulemans, @ginettelafit.bsky.social and others. Can’t wait to dive into it! 🤓 journals.sagepub.com/doi/10.1177/...

I am happy to share this new work as part of the Assessment special issue on Assessment, Measurement, and Registered Replication. We show how differences in construct operationalizations and study design influence power-based sample size recommendations in ESM research doi.org/10.1177/1073...

We are pleased to announce that the Society for Ambulatory Assessment Conference 2025 will take place from May 26-28, 2025, in Leuven, Belgium. www.kuleuven.be/600years/sch... You can subscribe to our mailing list via our website to stay up to date 😉

Since I'm new here I will start with some good news. I'm happy to share that the ESM Preprocessing Repository was awarded a SIPS commendation 🥳 preprocess.esmtools.com
