In a new paper, my colleagues and I set out to demonstrate how method biases can create spurious findings in relationship science, by using a seemingly meaningless scale (e.g., "My relationship has very good Saturn") to predict relationship outcomes. journals.sagepub.com/doi/10.1177/...

Tenure-Track Quant Psyc job opening at Northern Arizona University in Flagstaff. Areas of interest are pretty broad (SEM, multilevel, or psychometrics), the deadline to apply is coming up soon (Sept 15) if you're interested! careers.nau.edu/jobs/assista...

For those interested, here is a link to a new power paper: Hancock, G. R., & Feng, Y. (2026). nmax and the quest to restore caution, integrity, and practicality to the sample size planning process. Psychological Methods. yifengquant.github.io/Publications...

🧵 Very excited (w/ @omarjcamanto.bsky.social) to share our preprint tutorial for using our R 📦 dySEM for #dyadic data analysis with latent variables, in cross-sectional data sets. This paper has been literal years in the making, and provides three distinct tutorials. osf.io/preprints/ps...

‼️ New paper @ Child Development discussing why it is inappropriate to use traditional common factor models to model adverse childhood experienced (ACEs) and other stressor inventories ‼️ Read full (brief) paper at srcd.onlinelibrary.wiley.com/doi/full/10.... @srcdorg.bsky.social #PsychSciSky 1/9

New paper on dealing with MNAR intensive longitudinal data. Ran into this problem in an empirical study and didn't find too much in the methods literature on MNAR ILD, so this was the best I could come up with. Lots of opportunity to improve methods in this area! psycnet.apa.org/record/2025-...

New paper - coefficients like alpha/omega are commonly reported to summarize reliability. A sneaky nuance is that reliability is actually different at each score in the data. Paper tries to quantify how representative alpha/omega are of a typical score. link.springer.com/article/10.3...

This paper on intensive longitudinal reliability led by Sebastian Castro-Alvarez is one of the best I've read in a while -- the review was so thorough, the code was fantastic, and it answered any questions I had about IL reliability. Definitely check it out you work with ILD! osf.io/preprints/ps...

Next week, I'm teaching a 3-day workshop on DSEM for intensive longitudinal data using Mplus and registration is still open -- more information about the topics and registration can be found here! statisticalhorizons.com/seminars/dyn...

I don't understand how you can read and understand an evolving literature without keeping up with methodological developments. What are we supposed to do, just read discussion sections and take people's word for it?

The basic principle is that reviewers are tired, they're rushed, they're reading your and 10 other grants on top of their normal workload. Anything you can do to make it easy for them will help. Here's a list of my suggestions.

Who should you nominate as reviewers for your manuscript? After a long chat with a post-grad it appears that there's a lot of misguided advice out there. Thread 👇

This article gives a phenomenal overview of the history and evolution of best practices in measurement invariance and differential item functioning -- I can't remember the last time I learned so much reading a single paper, highly recommended! www.tandfonline.com/doi/full/10....

Posting for a Bsky-less friend -- New quant job posting for an Asst Professor at the University of Georgia in machine learning/data science/AI (very broadly defined) with applications to educational research. Due date is Dec 2! www.ugajobsearch.com/postings/403...

New Paper w/@melissagwolf.bsky.social- Dynamic fit cutoffs now support any covariance structure model (e.g., bifactor, hierarchical, & mediation models). Also supports categorical and non-normal outcomes Use the DDDFI function in dynamic package on GitHub www.tandfonline.com/doi/full/10.... /1

New paper w/ Roy Levy These 2 path diagrams are conceptually different (regression with a latent predictor that has 3 indicators vs. a factor model with 4 indicators) but they are mathematically equivalent. journals.sagepub.com/doi/10.3102/... /1

Psychology really needs to go back to square 1 on measurement. Even the major replications haven’t taken the lack of valid measures seriously. We are making up questions and questionnaires daily w/o validating constructs or tasks. This means our foundation is seriously shaky @jkflake.bsky.social

Yesterday I spent the day at an interdisciplinary meeting about rigor in science. It was a little depressing in what we are still working through regarding poor practices and incentives in science. Also, uplifting in that the movement to rectify the issues-has/is creating tools to move forward 1/n

How do we measure experiences of loneliness in daily life? A thread for clinical psychologists, relationship scientists, EMA nerds, and measurement geeks 🧵👇 Preregistration, data, analysis scripts, and materials at osf.io/cwgme/. #psychscisky #rstats #statssky

"Dynamic structural equation models with binary and ordinal outcomes in Mplus" - comes with a handy MPlus tutorial! link.springer.com/article/10.3... @dmcneish.bsky.social Somers & Savord

I somehow (!?!) missed that @dmcneish.bsky.social and Wolf have a dynamic fit indices Shiny app? Slapping this right into my measurement seminar slides. dynamicfit.app/connect/

Follow Dan because chances are that if you are wishing for a paper on an under-documented yet essential stats thing, he will have written it within the next 30 days

Most papers comparing clustered data methods use biostat/econ language, so I tried to write one using psyc/ed language that covers the origin of the independence assumption, how each method handles ind. violations, and types of questions best-suited for each method psycnet.apa.org/record/2024-...
