1/5 I'm excited to share that @chopwood.bsky.social and I's paper, "Angular Discrepancy and Personality Functioning Across Interpersonal Circumplex Surfaces," is now in press at Assessment 🎉 . Postprint, code, and materials: osf.io/3tw7a/

New meta by @peterhaehner.bsky.social et al (I'm a little middle author) on individual differences in personality change across the lifespan (229 studies, N = 230k) 10.1037/bul0000525 Cool finding (imo): For all Big Five, variance in change is greatest in youth, declining through young adulthood!

New theory piece on the mechanisms of personality change, led by @wiebkeb.bsky.social! In the extended ABC consolidation model, we extend previous accounts of how change in momentary states accumulates to lead to enduring trait change. (1 / 3)

How can we systematically organize and test the strategies used to reduce neuroticism? >> New research in Personality Science Authors: @ajwright.bsky.social, @peterhaehner.bsky.social, @chopwood.bsky.social, and @wiebkeb.bsky.social Read the full article: journals.sagepub.com/doi/10.1177/...

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 Check them out here: doi.org/10.1177/0890...

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 @mdkraemer.bsky.social @peterhaehner.bsky.social @wiebkeb.bsky.social @chopwood.bsky.social

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? osf.io/preprints/ps...

Special Issue 'Personality Dynamics'! We are happy to share this special issue from the Zeitschrift für Klinische Psychologie und Psychotherapie looking at interpersonal dynamics, motivational conflicts, and personality functioning in clinical psychology and psychotherapy.
