What a week at the IP-PAD meeting in Amsterdam, where our doctoral network met for training and a conference on youth politics!! I also presented a poster on my recent work on young people's future anxiety and political views (read more here: shorturl.at/Rpc0y)! Super grateful for the fun time! :)

New paper out with @boryslaw.bsky.social 🥳 In which we sketch out how to rethink measurement invariance causally for applied researchers. And provide a causal definition of measurement invariance! www.sciencedirect.com/science/arti...
Rethinking measurement invariance causally

Highlights:
It is preferable to work with a causal definition of measurement invariance
A violation of measurement invariance is a potentially substantively interesting observation
Standard tests for measurement invariance rely on strong assumptions
Group differences can be thought of as descriptive resultsConceptual graph illustration the central points of the manuscript. A group variable is potentiall connected to a construct of interest which affects items. Measurement invariance is violated if the group variable directly affects the items, for example by modifying the loadings from the construct to the items, or by directly affecting an itemTo make this less abstract, consider a scenario where students take an exam, R, meant to capture some ability, T, and then are admitted to a program, V, depending on their exam results: R → V. This is sufficient to result in a violation of the statistical definition of measurement invariance. Exam results and admission are not independent given ability because exam results have a direct effect on admission. Even if we know somebody’s ability (e.g., we know it’s very high), learning about their admission status (e.g., they were not admitted) can tell us something about their exam result (e.g., it may have been worse than expected). According to the causal definition, this in itself does not constitute measurement bias, which seems a sensible conclusion here. After all, the scenario does not involve any reason to believe that the measurement process varied systematically by admission status. Admission happens after the exams took place, it cannot retroactively influence the measurement process (and, for example, lead to unfair treatment depending on admission status).

Plot showing respondent demographic proportions compared to national proportions, overlaid on variable-specific regions of practical equivalence (ROPEs)Table showing sample characteristics compared to nationally representative Current Population Survey (CPS) estimates, with probability that the sample is equivalent to the national proportionAlso, it’s important to check the variable details to check for availability. While basic demographic variables like age, sex, marital status, etc. are available in both the monthly surveys and in the annual ASEC, more specialized variables are not.

Variables related to philanthropy and volunteering are only available in September (since they’re part of a special CPS Volunteer Supplement), and only in some years:
