I’ve now realized that LLMs are to statisticians what WebMD is to physicians.

Some recent shots of me presenting work on how bidirectional associations between loneliness and cognitive performance change over time using Bayesian estimation at the @geronsociety.bsky.social for the Center for Healthy Aging @pennstateuniv.bsky.social
Super cool new study by @kvanbogart.bsky.social looking into differences between chronic and acute loneliness!
Chronic loneliness harms health, but what differentiates chronic from acute experiences of loneliness? My newest publication dives into the subtle differences of loneliness in daily life. Read more: psycnet.apa.org/doiLanding?d...
Take a look at our new pre print for different approach on how to calculate the dynamic range of diurnal cortisol, led by the talented @kvanbogart.bsky.social
I will be damned if I allow a bunch of Confederate-waving January 6th apologists give the American people a lecture on flag waving. There is ZERO reason to enter an argument about patriotism with people who still worship traitors to America 150+ years later. They. Are. Breaking. The. Law.

Check out this new one from JAMA Pediatrics that I did the analyses for jamanetwork.com/journals/jam... We used Synthetic Control Method to evaluate the effectiveness of a coordinated county-level child sexual abuse prevention intervention program
Rates of Population-Level Child Sexual Abuse After a Community-Wide Preventive Intervention
This study tests whether a coordinated, community-wide preventive intervention could significantly reduce population-level incidence rates of child sexual abuse.

EMA/Daily Diary researchers! Do you have a dataset with momentary or daily loneliness among adults 18+? @kvanbogart.bsky.social is seeking datasets to support a coordinated data analysis Email Karina.vanbogart@northwestern.edu with a brief description of your dataset to be considered! #psychscisky
Yes, this administration is dangerous and cruel, but they are also shockingly dim and incompetent. Opportunities are everywhere. Make everything as hard as possible. Resist every demand. Refuse entry without a warrant. Don’t take the buyout. Their problem solving skills are 📉
I had no idea that I would get a burst of motivation after reading this @bandcamp.com article about @doseone.bsky.social , but here I am sciencing on a Saturday daily.bandcamp.com/features/dos...
The Resurrection of Doseone
After decades of heartbreak, loss, and reinvention, the prolific artist returns to his roots with “All Portrait, No Chorus”—a fearless reminder of hip-hop's boundless potential.

Oliver wanted to let @quantitude.bsky.social know that it’s been 5 years since Jiffy first appeared on the podcast. Happy Birthday, Jiffy!
This is a great write up of some really cool work that some of my colleagues in the Center for Healthy Aging at Penn State (and beyond) recently published including @leb112358.bsky.social!
Everyday physical activity, even light movement, improves cognitive processing speed, equivalent to reversing four years of cognitive aging. This highlights the short-term brain benefits of staying active. #CognitiveHealth #PhysicalActivity #BrainHealth #MentalWellness #HealthyLiving
This article gives a phenomenal overview of the history and evolution of best practices in measurement invariance and differential item functioning -- I can't remember the last time I learned so much reading a single paper, highly recommended! www.tandfonline.com/doi/full/10....
A Review of Some of the History of Factorial Invariance and Differential Item Functioning
The concept of factorial invariance has evolved since it originated in the 1930s as a criterion for the usefulness of the multiple factor model; it has become a form of analysis supporting the vali...

New paper: journals.sagepub.com/doi/pdf/10.1... This was a study I helped with that highlights a little known issue in child maltreatment research. Contamination bias can impact findings when children recruited for the non-maltreated control are or become maltreated during the course of the study
