We investigated the @hitop-system.bsky.social Brief Report (HiTOP-BR) in two German samples. Although there is room for improvement in certain areas, the HiTOP-BR provides a time-efficient and psychometrically acceptable assessment of the 6 HiTOP spectra. doi.org/10.31234/osf...

An Empirical Assessment of the Cost of Dichotomization of the Outcome of Clinical Trials We have studied 21 435 unique randomized controlled trials (RCTs) from the Cochrane Database of Systematic Reviews (CDSR). Of these trials, 7224 (34%) have a continuous (numerical) outcome and 14 211....

Some people are systematically better at judging others’ intelligence.
Who are the best judges? People WHO are intelligent themselves, have good emotion-perception ability, and who are high in well-being.

An important point! As we mention in our paper (p. 821), our sample is much more diverse and the observation period much longer than in typical RCTs. Therefore: "It remains unclear what changes might occur in this patient group without [active] treatment."

Last week, we lost our dear friend, colleague, and mentor, Cord Benecke, who passed away at the age of 60. We will never forget you, Cord! 💛 www.uni-kassel.de/fb01/en/depa...

Thanks for the interesting perspective! Do you think this has any implications for measuring personality functioning? For example, if the construct is understood in terms of learned self-related competencies, it seems plausible to build on "Operationalized Skills Assessment": doi.org/10.1159/0002...

Thank you, Miriam Henkel, for taking the lead on this. And thank you, @cordbenecke.bsky.social, for having the strength and courage to start this project, for hiring me 15 years ago, and for paving my way into academia! 💛

For me, it isn't about the results. It’s about solving methodological challenges in a way that leaves me reasonably satisfied. It’s about closing a long-standing chapter, while laying the groundwork for new questions. And it’s about the lasting bond this work creates with my co-authors.

Sometimes, doing research feels truly fulfilling. Working on this paper was one of those moments. doi.org/10.1037/ccp0...

Construct validity is a cornerstone of psychological science.

But too often, construct validation practices fall short, leaving uncertainty about what our measures really capture.

Why is that?

A year ago, 20 German personality psychologists came together under the leadership of John Rauthmann to assess the status of the field (not only from a German perspective). An English-language version of this paper (in press at Psychologische Rundschau) is now available:

New paper comparing latent dimensional, categorical, and hybrid models of internalizing psychopathology.

Dimensions win out, no surprise there. But the use of skewed latent dimensions as a comparison is a nice addition.
