#psychometrics — Public Fediverse posts

A set of posts coming out about the results of a #PhD project with high relevance to #CoreOutcomeSet and #Psychometrics communities:
https://www.linkedin.com/posts/marcikay_coreoutcomesets-cos-patientandpublicinvolvement-activity-7502703153407246338-nZ-J/

The posts describe how a PhD topic goes from application to a question one spends four years trying to answer. This first one focuses on this all started.

The MOSAIC study addresses that the @who.int #HealthyAgeing concept "psychological capacity" lacks clear conceptualisation:

The project has now published the definition and conceptual framework resulting from discussions in the International Working Group, which is now being further refined in a #Delphi study

Off for the day to Glasgow for the workshop
"What’s a difference that matters? Establishing patient-focused “good enough” margins”
organised by Beatriz Goulao.
#Glaschu #Psychometrics #PatientCentered

Psychology has instruments for meaning, for isolation, for the fear of being finite. They are not interchangeable.

Steger et al. (2006) on meaning. Weems et al. (2004) on Tillich's three domains of existential anxiety. Van Pachterbeke et al. (2012) on existential quest, without the religiosity constraint.

Fifteen papers, each with a verdict.

New Jamovi module functionality to determine appropriate model fit cutoffs for confirmatory factor analysis now available in easyRasch2jmv v0.4.0. Install/update from Jamovi Library within the app.

#rstats #psychometrics #stats #openscience

I've made a Jamovi module for modern psychometric analysis using Rasch Measurement Theory, "easyRasch2jmv", that is available in Jamovi's library. The module implements simulation-based (dynamic) cutoff values for conditional item fit and residual correlations, amongst other things. #psychometrics

The "easyRasch2jmv" module currently contains only 5 of the functions from my package. I prioritized these functions to enable analysis of the 4 basic psychometric criteria:

- unidimensionality
- local independence of items
- ordered response category thresholds (monotonicity)
- invariance (no DIF)

Afaik, simulation-based cutoffs for Rasch model fit metrics is not available in any other software, except my github-only R-package easyRasch. Some more details on the topic: https://pgmj.github.io/rasch_itemfit/ and https://pgmj.github.io/simcutoffs.html

If you are new to Rasch psychometrics, you will find a fair amount of resources and analysis examples here:
https://pgmj.github.io/raschrvignette/RaschRvign.html

This module is built using R packages such as eRm, mirt, and iarm.

The 2025 Trevor Levere Best Paper Prize goes to the team of the paper "The drop and the metric system: how an unruly unit survived revolutions"
https://www.tandfonline.com/doi/full/10.1080/00033790.2026.2636886

This is really great news and is for an excellent paper that I highly recommend reading!

Working myself in an area that has at best non-standard measurement units (at worst, some people would argue, is not measurement at all), I found this very interesting.

Pluralistic: Love of corporate bullshit is correlated with bad judgment (19 Mar 2026)

Just came across this blast from the past (2013):
https://rdcu.be/e7TDY
- daily assessments
- ordinal data multilevel #measurement
- DIF analysis

Couched as a preliminary investigation and pilot study, the analytic approach still sets a bar reached rarely by studies with such data.

“Instead of paying humans to join focus groups and complete surveys, #Auru uses thousands of #AI agents, or bots, to simulate human responses. It feeds #demographic and psychographic information into its models to create human profiles that match clients’ needs, and the results those bots spit out are being used for product #development, #pricing, identifying new customers and political #polling.”

Researchers have warned about the inaccuracies of treating #LLMs as human proxies (https://doi.org/10.1007/s10462-025-11297-5), but I wouldn’t be surprised #languageModels beat #qualitative interpretation of non-representative focus groups.

Having seen many (and done some) of these proof-of-concept studies myself, let's me wonder:

Are there still too few well-developed systems available?

Maybe someone reads this and feels we can get a collection of these together so that others can read up on them?

A recent post the @Mental_Elf picks up and explains a study on computerized adaptive testing, which is quite cool!

Psychometricians, what is your favourite application or study in the field of computerized adaptive testing with health-related constructs?

#Psychometrics

Interesting paper about the impact of missed cases on the accuracy of screening tools, likely of interest beyond autism research and practice communities.

I enjoyed in particular, that "[t]he strengths and benefits of blending epidemiology and psychometric perspectives to identify screening tools that are weaker than expected are discussed."

Steve Stich, Justin Sytsma, and I studied >70k people across the globe.

Apostates were more reflective thinkers.

That explained links between reflection and #religion.
