Measure when it matters!!
Egon Dejonckheere@dejonckheeregon.bsky.social · 3mo agoMost #ESM / #EMA studies capture daily-life patterns. But arguments😡, cravings🍫, panic episodes⚠️ or emotional peaks⚡ can happen between prompts. In our new From Paper to Practice blog, we discuss an #m-Path study on event- and threshold-based #burst designs: m-path.io/blog/how-to-...
In our new blog, we showcase 5 m-Path studies that adapted #ESM / #EMA protocols for: 🎗️ advanced cancer 🧩 intellectual disabilities 🗣️ aphasia after stroke 🧠 dementia 🍄 psilocybin microdosing They show that ESM / EMA is not a rigid protocol. Feasibility can be designed. m-path.io/blog/high-fi...
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:
Egon Dejonckheere@dejonckheeregon.bsky.social · 4mo agoIn #ESM / #EMA, how you ask “How do you feel right now?” shapes your data. Sliders 🎚️, smileys 🙂, drawing trajectories 📈, or emotion wheels 🎡: they all capture something different. We break down 5 approaches (and their trade-offs) in a new #m-path blog: m-path.io/blog/high-fi...
Cool new features to measure food intake!
Egon Dejonckheere@dejonckheeregon.bsky.social · 4mo agoMost #EMA / #ESM studies track eating in real time. But real-time doesn't automatically mean reliable. Two people log “pasta with meat”: Same entry. Different intake. A new #m-Path blog shows how dropdowns turn messy food logs into actionable data. Food for thought 🍝 m-path.io/blog/feature...
Response rates is something EMA all researchers worry about. Insightful blog about how to predict and improve your response rates!
Egon Dejonckheere@dejonckheeregon.bsky.social · 6mo agoWhy do participants stop responding in #ESM / #EMA studies? 📱🔔 Average compliance is about 7️⃣9️⃣%, but that hides massive variation. Our new m-Path blog reviews predictors of response compliance: study design, incentives, participant traits, and time effects. 🔗 blog.m-path.io/blog/blog-1/...
Super easy way to personalize sliders with a tangible effect!
Egon Dejonckheere@dejonckheeregon.bsky.social · 6mo ago✍️ New m-Path blogpost! Should #ESM / #EMA researchers show participants' previous rating? 🎚️ We tested three response formats in a real-world EMA study. One clearly outperformed the others, with consequences for reliability and affect dynamics. 👉 Read the blog: blog.m-path.io/blog/blog-1/... 📱
How to make good quality EMA items? A small investment to read, a big return by higher quality data!
Egon Dejonckheere@dejonckheeregon.bsky.social · 8mo agoWe’re launching a bi-weekly m-Path blog on #ESM / #EMA measurement, new papers & showcases. 🗓️ Every 2 weeks (Wed). First up: item quality. A paper by @gudruneisele.bsky.social introduces ESM-Q: a consensus checklist for good momentary items. 👉 Read the blog: blog.m-path.io/blog/our-blo...
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
Egon Dejonckheere@dejonckheeregon.bsky.social · 12mo ago🤔 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...

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!
Dr. Laura M. König@lauramkoenig.bsky.social · last yr.I very much appreciate @leonievogelsmeier.bsky.social's openness about challenges in studying markers for careless responding and how to address them live while collecting data - among them lots of issues in dealing with participants' digital footprints #SAA2025
@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 👩🔬 🧪 📑 !

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)

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!
Egon Dejonckheere@dejonckheeregon.bsky.social · last yr.@timonelmer.bsky.social @eveliensnippe.bsky.social and colleagues explored the potential of different triggering strategies in a #JITAI study on social support in depressed individuals. Pre-print: osf.io/preprints/ps...
