New preprint! osf.io/preprints/ps... The age-period-cohort problem is something that many researchers are vaguely aware of. There have been very cool advances in how to reason about it which don't seem to be well-known in psych. So, I've written a primer!

Abstract
Psychological researchers are interested in how things change over time and routinely make claims about, for example, age effects (e.g., personality changes with age) or cohort effects (e.g., differences in intelligence between cohorts). The age-period-cohort identification problem means that these claims are not possible based on the data alone: Any possible temporal pattern can be explained by an infinite number of combinations of age, period, and cohort effects. This concern holds regardless of the study design—it also applies to longitudinal designs covering multiple cohorts—and regardless of the number of observations available—it also applies if we observe the whole population. Researchers rely on statistical models that impose assumptions to pick one specific combination of effects. But these assumptions are often opaque and researchers may be unaware of them, resulting in a lack of scrutiny. Here,...

I'm so glad this site is taking off. My intro: I am an internal medicine physician and health economist. I am interested in identifying and intervening on the social and economic forces that lead to premature mortality in the U.S.. I have a whole lab that studies this: opportunityforhealth.org

Tech support question: How do I get citations to a judge's dismissal of a lawsuit against me to be counted in my Google scholar profile?

Did my account get put on a (bsky equivalent of a Twitter) list somewhere? Seeing a bunch of new follows from people I don’t know. They’re obvi not spam accounts and many are academic—but it is odd because someone like me doesn’t usually collect follows like this 😂

In a new paper lead by Ben Schlüter, we estimated about *1.2 million* youth (<18y) in the US have lost a parent due to drugs or guns since 1999. In 2020, drugs and guns accounted for about one in four parental deaths — about double the proportion in 1999. jamanetwork.com/journals/jam...

Paper titled: Youth Experiencing Parental Death Due to Drug Poisoning and Firearm Violence in the US, 1999-2020. Key points section reads: Question  What are the estimated rates of US youth (younger than 18 years) who have lost a parent due to drug poisoning or firearms?

Findings  In this cross-sectional study of the US population using publicly available data between 1999 and 2020, an estimated 1.19 million US youth had a parent die by drug poisoning or firearms. In 2020, drugs and firearms caused 23% of all parental deaths compared with 12% in 1999, and Black youth experienced a disproportionate burden, mainly due to firearm deaths of fathers.

Meaning  Results of this modeling study suggest that US youth are at high and increasing risk of experiencing parental death by drugs or firearms.
