The first preprint of my PhD is out! Our review maps choices that researchers make throughout an ESM study from start to finish, including reporting and open science practices. We compare our findings to previous literature where possible, but also provide novel insights! osf.io/preprints/ps...

🥳 PsyArXiv is back to normal operations 🥳 Thanks to the fantastic team of moderators (thank you all🙏), PsyArXiv has resumed normal operations. You can expect any newly posted or edited preprint to be moderated within 24-72 hours of submission. Learn more from our blog post👇 buff.ly/OtpsKhm

Is your preprint still pending moderation? See our recent post about how to make sure getting it approved is a smooth process: bsky.app/profile/impr... (pro tip: you can make edits even while it's in the moderation queue!)

PsyArXiv is now down to only ~40% of the backlog we started with, thanks to our amazing moderators 🎉 To all mods: thank you so much for your hard work! Did one of your preprints get approved recently? Help us show our thanks by liking and sharing this post :) #PsyArXiv #PsychSciSky

Just passed 25% of the backlog cleared 🎉🎉🎉 The dedication of our volunteers is impressive! Mods: Please feel free to come to office hours on Monday if you want to work in community. Mods-to-be: Hope to see you at Training #3 at 8 pm ET!

New and improved 😆 Those who were at the first training will know we needed to 🤦‍♀️ See you tomorrow, we're so thrilled to see all of the interest in supporting @psyarxivbot.bsky.social

🧠🧠🧠 PsyArXiv needs you! Please sign up to join our moderator team. First cohort is getting trained on next Monday, with more trainings to come. Easy way to give back to this crucial community resource. Students, postdocs, faculty, all welcome - come one and all!

My conclusion from this is that preprint servers (and journals!) are entering a new phase of cat and mouse trying to contain AI slop (n.b., not mundane AI use, but nonsense generation). Peer review as a filter scarcely does better to ID this stuff. We need new & better tools to ID trustworthy works.

Thoughtful piece about the influx of suspicious #preprints (some involving AI) to PsyArXiv & other preprint servers. Wee mention of me and some of the preprint monitoring I've been doing in collaboration with PsyArXiv. Servers are not going to take this lying down. #OpenScience

Does anyone know of a direct comparison between EU countries in terms of metrics used to evaluate universities and/or academic researchers? I'm especially interested in whether one can contrast countries that use N publications with those that don't. I suspect it's not so simple though

A new study, based on an analysis of thousands of publications and their authors and editors, shows paper mills are just part of a complex, interconnected system that includes publishers, journals, and brokers. scim.ag/3H9kwwQ

Watching to see if my code will stall or keep grinding through downloading preprints with the OSF API is *almost* as tense as last night's penalties... 🙃. #OpenScience

🆕 Following requests from authors, we have increased the word limit for all regular papers in Archives of Suicide Research to 5,000 words (Introduction, Methods, Results & Discussion)

Glad to see @cos.io coming out with a statement about this after an influx of suspicious preprints hit PsyArXiv at the start of July. Many more have appeared since the first one I spotted. I Automated checks can only go so far & documenting all of them is a lot of work. #OpenScience

I've been working on follow-up to When It Is Darkest, after a hiatus. When I published When It Is Darkest, I did so without an agent. But I think that an agent would really help for book #2. If you're an agent or know an agent who might be interested in representing me, please get in touch. 🙏

New blogpost. The shitshow that results when a publisher fails to check up on their peer reviewers, with authors caught up in a nightmare process. deevybee.blogspot.com/2025/07/trou...

New blog post 📣 by @ccp-kuleuven.bsky.social's @millapihlajamaki.bsky.social on six things you can do with your ESM items apart from your main, substantive analyses. Check it out here: esmitemrepositoryinfo.com/blog-posts#M... #ESM #OpenScience #Measurement

I recently taught a course on minimizing mistakes in science. The most convincing argument to my masters students was that you never check mistakes that support the expected outcome, you only check if the outcome is unexpected. That's a hugely important bias!

As an update to the AI preprints issue with PsyArXiv, support responded and said the problematic preprints had been removed. Thanks to @cos.io & @improvingpsych.org, & @katiecorker.bsky.social, @dermotlynott.bsky.social, & @ianhussey.mmmdata.io for their helpful responses.

Just noticed actually quite a lot of preprints shared via @psyarxivbot.bsky.social in the last 24hrs that seem like they might be AI-generated. They make little to no sense and do not seem like scientific manuscripts. Also lots of repeats. Anyone from PsyArXiv on this? @improvingpsych.org @cos.io

Over recent weeks I have heard about some trials struggling with the phenomenon known as “Lasagne’s Law.” I’ve flagged this issue before, but always good to revisit it and discuss what can be done to minimise it 1/7 #MethodologyMonday #121

Anyone from PsyArXiv on here? I'm curious if the moderation or other checks include checking to see if a preprint is AI-generated. @cos.io @improvingpsych.org #Preprints #OpenScience

Please share! New partnership with RSABI. Fully funded PhD scholarship (UK students only): Towards an enhanced understanding of suicide risk among those from agricultural backgrounds. Supervised by me and @katierobb.bsky.social Closing date: 21st July 2025 🔗 www.findaphd.com/phds/project...

Have you used the @esmrepository.bsky.social in your research, e.g., to find items, contribute items, conduct measurement research, etc? We need your help! Please share. #ExperienceSamplingMethod #OpenScience @ambulatory-assessment.org

📢 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

This looks like a really helpful resource. In our lab reading group this week, we read @abalkina.bsky.social & @deevybee.bsky.social's paper on paper mills (www.proquest.com/openview/055...). Qs came up about what to do if you spot something questionable, so this is a nice follow-up. #OpenScience

Important read for suicide researchers (& everyone doing prediction modeling) on why sample size matters for machine learning-based prediction models. I see lots of articles using ML for suicide/suicide risk prediction with very small sample sizes & few cases. Let's move towards better practices!

And even better, have an ORCID profile that’s open not private, and populated with your institution history, variants of your name you’ve been published under, and some publications to help with this kind of disambiguation.

Super happy of being invited to give a talk at the Leuven Statistics Day at the same time that #SAA2025 was happening. I presented some recent theoretical results on the consequences of measurement error on bias and statistical power in multilevel models osf.io/preprints/os...

I’m also super proud of @lisapeeters.bsky.social for presenting the first results of a massive registered report systematic review mapping the whole process of ESM research from design, preprocessing, and data analysis rr.peercommunityin.org/articles/rec...

There is an urgent (!) need for more awareness, more skills and more solid advice on how to practice #OpenScience *responsibly* before we see more cases like this 👇🏻

My editorial on how journals can earn trust. We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that. journals.sagepub.com/doi/full/10....
