My first PhD paper is out ππ£
We examined transactions between Big Five traits and first sexual intercourse across up to 10 years and ~5,000 German adolescents.
Extraversion stood out ππ§
Agreeableness + openness showed interesting patterns as well

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?

How does providing informal care affect people's well-being? @wiebkeb.bsky.social and I used longitudinal data to examine this question across different well-being aspects, 3 countries (π³π±, π©πͺ, π¦πΊ), and several moderators.

Very happy to see this out now in JPSP!
We used 5 datasets (N = 128K) to do a deep dive into within-person variability for long-term personality development, a metric common in short-term dynamics work but (sadly!) pretty disregarded longitudinally (1/8)

Do people become more alike across the lifespan? Is the variability of personality traits changing across time and age?
In our meta-analyis on changes in personality variability, we integrated data from more than 300 longitudinal studies to answer these questions.
