Nietzsche once observed that "our emotional life is least clear to ourselves" (Safranski, on Nietzsche). It’s a profound thought, but you don’t need a 19th-century philosopher to tell you that measuring emotions is a complex challenge. Here is a breakdown on how to measure emotions in practice:

Cool new features to measure food intake!

Response rates is something EMA all researchers worry about. Insightful blog about how to predict and improve your response rates!

Super easy way to personalize sliders with a tangible effect!

How to make good quality EMA items? A small investment to read, a big return by higher quality data!

Very cool study by Laura Dewitte on how the #ESM / #EMA methodology can even be used in a population with dementia. Results: ✅ 0 dropouts ✅ 80% response rate ✅ low reported burden ✅ positive participation experiences ✅ substantial within- and between-person variability

🤔 Can people with dementia participate in intensive experience sampling studies via smartphone? 🧐Yes, they can! Even with high-frequency sampling schemes (8 times / day)! Work from @lauradewitte.bsky.social in npj Dementia: doi.org/10.1038/s444...

📱 Want to know when to schedule your #EMA / #ESM beeps for the highest completion rates? ⏰ Timing matters: some moments during the day and week are more receptive than others. See: link.springer.com/article/10.3...

Cool work by Vanhasbroeck et al. (2024) relevant for #EMA / #ESM research: 🔁 Moderate to good retest consistency in fast-paced affective measures 📏 Whether it is VAS, Likert or 2D affect grid: Scale type doesn't seem to affect reliability! 🔗: link.springer.com/article/10.3...

📢 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

Ultimate respect for dj Alter Egon @dejonckheeregon.bsky.social !

What an insane crowd at the #SAA2025 m-Party (also sublime dance moves)! 💃🪩🕺🏼 #EMA researchers know how to party! 👊🙏

Really happy that @leonieschorrlepp.bsky.social presented the results of our mixed-methods study uncovering response processes in ESM studies 📱. Take-away: people are very inconsistent in how they come up with their answers. Talking to participants in key! 🔐 #SAA2025

Very exciting to see the work from @katiehoemann.bsky.social at #SAA2025! Participants were able to voice record a description of events. Katie clustered these over many different topics. 2 fun ones: - Complaints about rain (study was in Belgium 😅) - Complaints about the study itself (ESM...)

#SAA2025: Laura Sels talks about daily emotional suppression and differences between males and females.

I had a great time discussing my work yesterday at #SAA2025! If you are interested in building sets of variables, then check out the R package @aaronjfisher.bsky.social and I made: github.com/nicolasleena...

@leonievogelsmeier.bsky.social showing the true complexity of science!

@rayyantutunji.bsky.social showing at #SAA2025 that wearable data (EPA) is not enough to predict mental well-being (R2 = 0.01). My bet is more on timing (triggering) surveys compared to leaving out surveys. Impressed by the commitment to correct validation (not even touching test set until later)!

The things you see when you're at @saa2025leuven.bsky.social! If you're looking for ZI 02.21 and you find yourself in a mini museum, you're heading in the right direction! #SAA2025

Cool #SAA2025 talk from Niels van Hasbrouck about how an extreme response style can have a severe effect on affect dynamics. Should we push everyone to have the same response style by only allowing discrete answers?

Triggering questionnaires at the right time will become increasingly important in research! I am looking forward to see what researchers will build with these features 👩‍🔬 🧪 📑 !

Very happy with this new feature that automatically creates individualized invitation pages for all your participants! 📫🔥🔓

Small new #EMI (ecological momentary intervention) feature that makes it very easy to create adaptive module screens or psycho education interventions. Used for: - adaptive presentation of exercises - Only show relevant modules for a participant (modules that actually interest the participant)

For those who are interested ESM feedback, happy to announce that a new paper is out, in which we combine qualitative and quantitative feedback! Innovations include clock graphs, stacked graphs, and word clouds with sentences. www.sciencedirect.com/science/arti...

m-Path goes to Amsterdam! 🇳🇱 Science and Tech-companies meet each other @ the Nemo Science Museum to exchange knowledge and innovative solutions to measure and reduce stress in daily life! 🧑‍🔬📈📲

Using fixed (e.g. stress>70) thresholds when triggering interventions or questionnaires is not optimal. For example, some participants never reach a stress level of 70, some are always above 70. This pre-print shows that triggering with personalized thresholds, solving this problem, is possible!

Very cool paper on an ambulatory assessment based blended care implementation! #blended #ESM #EMA

Interested in ESM but don’t know where to start? On Thursday May 22 we organize a workshop on how to design and analyze your ESM study! Register here: forms.office.com/e/2jUtLe2t2R. With @domimaciejewski.bsky.social, @dejonckheeregon.bsky.social, Marlies Houben @tilburg-university.bsky.social

New work in @clinpsychrev: "EMA in psychotherapy research" EMA: ✅ most used in clin *research* ✅ often to predict symptom changes ✅ rarely implemented to impact therapeutic processes ✅ research needed on actual EMA benefits in *practice* www.sciencedirect.com/science/arti...

New website!

Experience sampling conference AND Alter @dejonckheeregon.bsky.social Dj set 🤩😍🤯

Dr. Maarten Piot explaining how he developed m-Path’s clinical dashboard via a user-centered design in close collaboration with clinical practitioners! #PhD #EMA #ESM

Our Chief Measurement Officer at m-Path just obtained her PhD! Congratulations Dr. Cloos!

Proud to be part of such a cool project!

Question to ESM researchers: Is there any research available on the pros vs cons of the examination of ESM items in a fixed vs random order?

🧠 In recent months, I've been asked frequently whether the #AppleVisionPro is worth investing in for #MentalHealthcare organizations. Following extensive testing - with insightful assistance from my 9-year-old son, a VR enthusiast with nearly 5 years of experience, here are 3 key takeaways.

Now that I understand starter packs, I've (re)started one for people interested in all things psychotherapy personalization and optimizing treatments to the individual 😊 Anyone welcome! And consider joining our Person-Centered Treatment and Prevention Collaborative group! go.bsky.app/FXmURQf

I am slowly adding more people to my Mental Health starter pack. My aim is to add people who post actively and at least some of their posts are about #MH, to make the list as useful as possible. Suggestions are welcome, this list is mostly crowd sourced! #academicsky go.bsky.app/MfWbYvP

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

Yesterday we moved office from our offices at KU Leuven (university) to our new m-Path offices. We took one last picture in front of the PSI. Some of us had worked here for more than 14 years. PSI, you will be missed!

We are looking for a PhD student to join our team at LMU Munich. You will be part of a project aiming to understand the mechanisms driving the reduction of repetitive negative thinking (RNT). The project is funded by the Wellcome Trust, collaborators Ed Watkins/Exeter and Michelle Craske/UCLA. (1/2)

Welcome everyone to this very first EMPOT tutorial! The automated YouTube subtitles are not perfect yet :). Currently creating 3 tutorial videos for researchers new to the m-Path/empot platform!

1/2 As most of you know, m-Path is preparing a spin-out from our university. In the coming year, we will move the data from the university servers to external hosting. Which of the following has your preference? Please ask all your DPO's! - OVHcloud - Exoscale - Microsoft Azure - Other

Added new functions to PseudoR. PseudoR can be used to adapt a survey in real time. e.g.: -as.responsetime: use to adapt a survey to a participant that answers too quickly -distm: adapt survey if participant is close to a specific location Let us know if you are still missing functions!
