Analysis of treatment effects on psychological networks using data from the IRW: "Our results show that causal effects on network strength are both common and uncorrelated with effects on network state." New work from @jbgilbert.bsky.social

As the IRW approaches 1000 tables, there is an obvious need for better approaches when querying appropriate tables. We've added more metadata (including human annotation) and improved R-based functionality for doing just that! itemresponsewarehouse.org/metadata.html

Simulation studies are common in psychometrics. We are trying to make them more relevant to practice by increasing their connection to empirical data. Feedback welcome!

1/ What might data-rich #psychometrics research look like? As a first example, consider @jbgilbert.bsky.social on heterogeneous treatment effects (HTE). Josh uses #irt to examine item-level HTE, with insights drawn from 75 datasets across 48 randomized trials (arxiv.org/abs/2405.00161).

Do you need educational and psychological item response data to do your research? The IRW has 600 item response datasets (more coming!), distributed in a standardized format and ready for analysis.
