🚨 New preprint: We compared 13 methods for detecting momentary careless responding in the WARN-D data (206k+ obs.). Tutorials guide you through each method. The takeaway? Diverging results, inherent subjectivity (to varying degrees), and a clear need for further validation. osf.io/preprints/ps...

New preprint! Does data quality drop when participants respond to #EMA / #ESM surveys in the presence of others? We explored this in a pooled analysis of 4 ESM studies and found (subtle) shifts in burden & response behavior depending on participants’ social context: doi.org/10.31234/osf...

How Accurate & Consistent are Self-Report responses via Visual Analogue Scales (VAS) in Ecological Momentary Assessment & Digital Studies? Examined in a massive EMA study (N = 3,761), our new #OpenAccess piece on this is just out: online.ucpress.edu/collabra/art... #PsychSciSky #AcademicSky 🧵:

Experienced, bothered by, or both: People differ in how they understand the Patient Health Questionnaire (PHQ) items: https://doi.org/10.31234/osf.io/jcsq8_v1

Our paper "A fragmented field" has just been accepted at AMPPS. We find it's not just you, psychology is really getting more confusing (construct and measure fragmentation is rising). We updated the preprint with the (substantial) revision, please check it out. osf.io/preprints/ps...

While I was unfortunately unable to travel to Belgium for the conference, I have uploaded the recording+slides+code for my #SAA2025 talk on multilevel multiple imputation for EMA research here: osf.io/xjg24/files/...

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

Do you like coffee ☕, ambulatory assessment 📱and #OpenScience 🔑? We are hosting a contributors’ café during lunch breaks & poster sessions @saa2025leuven.bsky.social. Come find the café to have a cup of coffee and contribute your items to the repository! #SAA2025 🧵 ⬇️ 1/4

Deviations from preregistrations seem to be the norm, not the exception. Great to see more guidance on how to navigate them thoughtfully. Emily Willroth and @oliviaatherton.bsky.social's paper is another helpful resource: doi.org/10.1177/2515...

New article in MBR⭐: www.tandfonline.com/doi/full/10.... We show that latent Markov factor analysis (LMFA) can detect different types of careless responding in experience sampling data while also accounting for changes in attentive responding. With Esther Ulitzsch and @joranjongerling.bsky.social

It was a pleasure to present some work on improving ESM/EMA assessments at the Center for Self-Report Science at USC yesterday. What a bunch of great people with so many interesting perspectives – I’ve already learned a ton!

Are you heading to @saa2025leuven.bsky.social? Fancy extending your stay in Leuven to learn more about #OpenScience for Experience Sampling Method research with @ginettelafit.bsky.social & I? We are running a one-day course after the conference! More info here: tinyurl.com/334rytta

📣 New blog post! What if ESM data grew on trees? 🌳 Read more about the EMOTE database in our latest blog by Imogen Smith, Pete Koval, @elisekalo.bsky.social, & Daniel Russo-Batterham! esmitemrepositoryinfo.com/blog-posts#E... #ESM #EMA #OpenScience

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🧵

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

What makes a good ESM item? We asked 42 ESM/EMA experts this question in a Delphi study, and the result is the ESM-Q: A consensus-based quality assessment tool for ESM items. Now accepted at #psynomBRM. Updated preprint: osf.io/preprints/ps... Thread below.

Well-deserved SIPS commendation for the ESM Preprocessing Gallery! Since many errors happen during preprocessing, we can't stress its importance enough! This excellent tool helps applied researchers navigate all the steps they have to take before analyzing their ESM/EMA data

🌟New preprint on using latent Markov factor analysis for detecting careless responding in intensive longitudinal data when the measurement model of the attentive responses is non-invariant. osf.io/preprints/ps... with @joranjongerling.bsky.social and Esther Ulitzsch

Still time to apply for our #PhD vacancy!⏰ The project involves investigating suicidal thoughts & behaviours using experience sampling & epidemiological data, living in Belgium 🇧🇪 & Australia 🇦🇺, & working with me, Gudrun Eisele, @ginettelafit.bsky.social & Angela Clapperton. Please share!

Ever wondered how anhedonia can be measured with experience sampling? Check out this systematic review of 102 ESM studies in anhedonia research led by Joanne Beames: osf.io/preprints/ps...

New PhD position at the Center for Contextual Psychiatry! With @oliviajkirtley.bsky.social & Ginette Lafit on developing personalised real-time models of suicide risk and protective factors www.kuleuven.be/personeel/jo...

Happy to share the result of our Delphi study with 40+ international ESM/EMA experts: ESM-Q: A Consensus-Based Quality Assessment Tool for Experience Sampling Method Items osf.io/preprints/ps... Part of the ESM item repository project (www.esmitemrepository.com) co-lead by Anu Hiekkaranta (1/4)

Ever wondered how people choose numbers on emotion scales in #ESM studies and whether they stay consistent? 🤩 We just finished data collection for our study aimed to uncover response processes in emotion assessment (i.e., how participants interpret & respond to questions) (1/8)

📐📏Happy to share that our article "Assessing and Accounting for Measurement in Intensive Longitudinal Studies: Current Practices, Considerations, and Avenues for Improvement" is accepted for publication (with @joranjongerling.bsky.social and E. Maassen) #teamscience #ESM osf.io/preprints/ps...

New post at The 100% CI: Do we have a problem with construct and measure proliferation in psychology? It depends who you ask and it varies by subdiscipline. We respond to a recent piece by Iliescu et al. and try to find some common ground. www.the100.ci/2024/03/22/o...
