Made it to #IMPS2026 registration at Yonsei University, Korea! So excited to see everyone around this week 😄

Happy to share that our paper, "Analyzing multivariate formal dynamic models in psychology: A tutorial using graphical tools," has been accepted by Behavior Research Methods 🎉

I'm planning to go to #IMPS2026 in KR this summer! It will be my first time for IMPS and I'm very excited : ) I'd like to share some recent developments on fitlandr (cran.r-project.org/package=fitl...), and I was wondering if anyone's organizing a symposium and would like some nonlinearity? 🙂

fitlandr: Fit Vector Fields and Potential Landscapes from Intensive Longitudinal Data

A toolbox for estimating vector fields from intensive longitudinal data, and construct potential landscapes thereafter. The vector fields can be estimated with two nonparametric methods: the Multivari...

I am very happy and honored to share that I successfully defended my PhD thesis, Advancing the Analytical Tools for Understanding Complexity in Behavioral Science, on November 20th and received my doctorate (cum laude) from the University of Groningen @rug.nl ! 🎉

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 Find out more: 🌐 openesmdata.org 📝 doi.org/10.31234/osf...

I’m very happy to share that my PhD thesis, Advancing the Analytical Tools for Understanding Complexity in Behavioral Science, has been approved by the assessment committee! 🎉 I will publicly defend my thesis on November 20th at 12:45😉 Looking forward to it!

Made it to @saa2025leuven.bsky.social (after 6 hours train from Groningen 🤣) Too late for the registration today but I'm certainly at the right place! See you tomorrow : )

ICYMI: decision to cut 5 international bachelor psychology programs in NL poses serious threat to psych science nationally & internationally, given how much research conducted here has historically punched above its weight in terms of per-capita output. eiko-fried.com/nl-psycholog...

Cutting international bachelor programs threatens psychological science » Eiko Fried

Dutch universities decided to throw international bachelor programs under the bus to appease the government. This is a terrible idea.

Examining the research methods of early warning signals in clinical psychology through a theoretical lens - BMC Psychiatry

Background The past few years have seen a rapid growth in research on early warning signals (EWSs) in the psychopathology domain. Whereas early studies found EWSs to be associated with sudden changes ...

I had a blast spending a whole week working on improving the measurement of intensive longitudinal data with so many smart and kind people. Like a nerdy school trip with friends. Thank you 🙏 @eikofried.bsky.social @bringmannlaura.bsky.social @miguelsilan.bsky.social Josip razum #LorMITNB

Hi #LorMITNB forks, this may be useful of you want to follow other participants ; ) go.bsky.app/42Nh8oA

Amazing to see so many early career folks who care deeply about improving measurement of intensive longitudinal data #LorMITNB

Not sure if I’m doing this right, but I’ve had a go at starting a ‘Reconceptualising psychopathology’ starter pack (e.g., HiTOP, RDoC, dynamic systems, clinical staging). Please do send me suggestions or requests to be added! go.bsky.app/Pek9ycQ

I made an attempt at a bsky psychometrics starter pack with people who work on or largely with psychometric tools! Please reskeet and (selfl!)nominate to help me fill my many and varied blind spots and make this a useful and balanced resource #rstats #psychometrics go.bsky.app/6oGLp7D
