New post! Have you been indifferent to invariance? @dingding_peng argues that measurement (non-)invariance gets a lot more interesting once you think about it from a causal perspective. the100.ci/2024/01/10/a-c…

🚨New paper 🚨The Cantril Ladder is the most widely used well-being survey worldwide. It has been administered 2m+ times in 140+ countries and is the basis for the “world happiness rankings.” Our new paper suggests it may be seriously flawed. Scandinavian countries historically

Factor analysis enormously overplayed in choosing items for patient-reported outcome development for assessing patient status and intervention impact. Patient-importance a far better criterion. doi.org/10.1016/s0895-…

Did you know that you can think about confirmatory factor analysis as a multilevel model? SEM and MLM can seem like disparate methods, but they aren't! Mairead Shaw and I developed this to demonstrate the connection: ncme.org/itemsportal/di… So what's in this module? 1/

Modern Modeling Methods 2024 updates: 1. I have updated the website (finally)! 2. MMM Conference registration is now open. 3. We will be sending decision letters to everyone who submitted MMM proposals by the end of the day tomorrow. modeling.uconn.edu

Logistic MLMs are often described as "simple extensions" of linear ones, but the first step, calculating the ICC, is way more complicated! Sean noticed this when taking my class and ultimately developed a tutorial with example data and code. I learned a lot, I hope you do too!

Nope! Not that kind of model! The 2024 Modern Modeling Methods conference is June 24-26, 2024 @UCONN. For more information or to register for the conference, go to modeling.uconn.edu quantitudethepodcast JK Flake 📈📏 @doinkboy - Can you help spread the word?

We'll likely have a 2-year postdoc position in our lab (MetaMelb) in psych at Melbourne Uni, starting later this year. If you have a PhD, do relevant stuff, & want to spend 2 years in Melbourne studying psychology research methods & practices, please get in touch! Please share!

= Help: Meta-analysis coder needed as coauthor = We have an experimental Meta-Analysis Registered Report on action-inaction that received a Stage 1 in-principle from Peer Community in Registered Reports. 🤜Looking for coder coauthor to join team to help us code.🤛 Details 👇

The lab did Modern Modeling Methods practice talks yesterday. Who all is heading to Connecticut next week for the conference?

A gem from the program at the Psychometric Society. Nine speakers for a manel, that might be a record! 🏆

Dear Quant community, sharing some good news from Psychometrika: "Dear Members of the Psychometric Society, We are pleased to announce that starting 2 September, Psychometrika will be accepting submissions of papers through its new website:mc.manuscriptcentral.com/psychometrika. From now on,

We wrote a short paper about our lessons learned doing registered reports. Check if out if you are interested to learn more about RRs and/or are considering getting started with RRs!

Proud of the Psychometric Society having the courage to transition Psychometrika to Open Access. Practically all APCs are covered by TAs (see bit.ly/3NiAy6T) and for authors not covered will be waived! Support open science, send your best work to bit.ly/4eXTvYp
