delighted to see this published 🙌 using EMA, we (with @roryoc.bsky.social) investigated suicidal ideation in daily life. we found that it arises from an interaction of within-person increases in loneliness and an individual’s level of personality functioning psycnet.apa.org/fulltext/202...

Construct validity is a cornerstone of psychological science.

But too often, construct validation practices fall short, leaving uncertainty about what our measures really capture.

Why is that?

We (@stmllr.bsky.social) tackle this question in our 𝗻𝗲𝘄 𝗽𝗿𝗲𝗽𝗿𝗶𝗻𝘁:

The package formerly known as papercheck has changed its name to metacheck! We're checking more than just papers, with functions to assess OSF projects, github repos, and AsPredicted pre-registrations, with more being developed all the time.

The Big Three-Mini: Development of a Cross-Culturally Invariant Indicator of Fundamental Character Constructs: https://osf.io/nketr

On Prolific, "we estimate that about 34% of online study participants use LLMs to answer open-ended questions atleast some of the time..."

Seems like a very timely paper for behavioural scientists using online samples: osf.io/preprints/so... ;

We really need more papers on this issue

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

New preprint with @uschroeders.bsky.social. In a simulation study, we explored the predictive performance of ML models across various data conditions typical for psych research. Spoiler: Data quality limits the performance of ML models in a similar way to more "traditional" regression analyses.
