My first PhD paper is out 🎉🐣

We examined transactions between Big Five traits and first sexual intercourse across up to 10 years and ~5,000 German adolescents.

Extraversion stood out 🔄🧠

Agreeableness + openness showed interesting patterns as well

Clinical psychology depends on scientific evidence, but research from @chopwood.bsky.social et al. suggests that the kinds of data most commonly produced may not always align with what clinicians find most useful in practice. Read the article in American Psychologist: doi.org/10.1037/amp0...

Very excited to share our preprint (in press at Psychological Science) titled
"Associations between meat consumption and depression are small and unlikely to be causal". Have a read: lnkd.in/eM8Cd6Ss

New preprint!

Many claim that first sex is a huge risk for teens. We tested that claim in a large, nationally representative German sample. Core question: Do first sexual experiences harm adolescents, or do they reflect prior well-being?

Right. They tested the claim that plant based diet causes depression etc via vitamin deficiency. This is the first experimental evidence I’m aware of.

I value feedback from students a lot and regularly change my approach based on their helpful suggestions, but the way they do teaching evaluations in North America are really bad for both equity and education.

But I stand by the frame bc these can all be true: /researchers should try to do studies that matter and asking clinicians helps find out what that is, /between subjects studies are over represented because they are easy to do, /it is still hard to translate clinically useful research to practice.

My thinking was that I often hear a reflexive attitude among researchers that clinicians don’t have time or ability to make use of research, and this produces a cynicism that defends against engaging with clinical ppl and reflecting on the value of our work. Arguably a bridge too far here.

I get it. We were not trying to imply we’d found the silver bullet to imp sci but I can see how, to a person in that area, it came across as naive or sensational, and the focus of reactions on here reinforces your point. In retrospect maybe we (mostly I) knew that would grab attention

Maybe you’d like this alternative framing better?: clinical psych research is disproportionately influenced by how easy it is to do studies rather than how likely it is to help solve mental health problems
