I would like to start a veridicality movement in clinical psychology. I've realized this is my primary concern with network models. We *want* them to convey information flow and dynamics, but they're just lag-1 regression models at (relatively) glacial time scales. They don't reflect what we want.
Thrilled to announce the Oxford Psychological Networks Summer School (OxPNS)!
This is the first-ever psychological network analysis workshop in the UK, to be held in magical Oxford from June 22-26, 2026.

📱🤔 A classic
#ESM /
#EMA dilemma: Own smartphone or research-dedicated device?
It sounds trivial, but this choice subtly shapes how people respond. A rarely cited paper tested both, with non-obvious takeaways.

Should participants use their own smartphone in ESM / EMA studies?
We’re launching a bi-weekly m-Path blog on

#dataviz #ggplot2Cool study in JAMA Psychiatry confirms what many have suspected for a while: PHQ (depression questionnaire) instructions are widely misinterpreted by patients. It is unfortunate that a questionnaire as shitty as PHQ-9 has become so ingrained & ubiquitous

📑 New paper by Stephanie Wong et al. captures exactly why m-Path exists.
A phased, user-centered study showing how EMIs can be built quickly, affordably, theory-informed, and at scale, and they used m-Path as their no-code platform.
What struck me was why they needed a platform like ours 👇:
In their review of 149 mental health apps, only 28.9% were publicly available and just *8.3%* could be adapted!
This highlights :
❌ Single-study apps are often not shared
❌ Prototypes aren’t flexible or maintainable
❌ Costly developer dependence
❌ Content that can’t be adapted afterward
However, they showcase m-Path can be the alternative:
✔️ Full researcher independence in developing the app
✔️ Flexible building blocks they can fully tailor
✔️ Fast, theory-driven EMI development
✔️ A validated end product that outlives a single project or grant

We feel deeply thankful (and a little proud too). 💙
When we measure personality multiple times in a study, does it matter if we ask people about their personality *in general* or *since the last time point*?
Turns out: yes!
We found differences in internal consistency, Ms, & SDs but not in the underlying constructs 🧵

We’re excited to introduce a powerful new addition to our mobile sensing packages: m-Path Keyboard Tracking!
#EMA #ESM #mobilesensing #behavioraldata #psychresearchOur custom keyboard logs what participants type on their phone – making it possible to:
✍️ Analyze keystroke behavior (e.g., typing speed, pauses, corrections)
🧠 Conduct content analyses of written text across messaging apps, notes, and more
💬 Study naturalistic language use in digital contexts
As always, privacy is a priority — participants remain fully informed and in control (we added a mute button 🤫 and allow participants to remove sensitive text entries).
