Wie hÀngen Überzeugungen seitens Psychologie-Studierender im klinischen Master mit dem Einsatz von Expositionen mit Reaktionsverhinderung bei Zwangsstârungen zusammen?

Gerne an Master-Studierende weiterleiten, danke!

Das was ΓΌber bisher Dagewesenes hinaus geht ist die Vernetzung und die Machtstrukturen. Da ist es aber gerade sehr wichtig zu differenzieren, damit man nicht in das ΓΌbliche "die da oben" (oder schlimmeres) fΓ€llt und Spekulationen zu lassen.

Die Grâße finde ich nicht das entscheidende Merkmal. Die Zahl der Opfer wird auf um die 1000 GeschÀtzt, das ist etwas 1/3 der FÀlle schweren(!) sex. Missbrauchs an Kindern in Deutschland pro Jahr. Und was Organisiertheit und weitgehende Straffreiheit angeht gabs schon vorher die kath. Kirche.

I always treated them like this: apparently someone more skilled in R than me decided that it's a good idea to have them, I won't bother understanding them, and if they act up they get coerced into a data frame.

It's reassuring to live in a country where this would be unconstitutional. Yes, in good old free-speech stifling, regulating, Nazi-criminalizing Europe :)

FWIW in contemporary Q methods I saw some kind of prototype flagging, which can then be followed up with, e.g, interviews to establish this. But that's basically adding another type of assessment.

I completely agree that virtually all these approaches that work with psychometrics alone lack this aspect of functional or mechanistic explanation. I also doubt that this can be resolved by switching from one statistical model to another.

You are essentially describing a Q-sort, right? Then you have basically generated data for which clustering works.

New paper from our team: Can ML identify which adolescents benefit most from school-based mindfulness?

In 8,376 students (MYRIAD trial), models detected statistically significant but clinically negligible differential effects (d β‰ˆ .07–.08).

Record of the past or reflection of the present? Fluctuations in recollections of childhood adversity and fluctuations in adult relationship circumstances Adverse childhood experiences (ACEs) are studied as predictors of lifespan outcomes, yet their reporting is assumed to be stable across time. However,…

Adverse childhood event reports are largely stable but also fluctuate, which is related especially to current relationships with parents. More support or less strain associated with fewer recalled events. Pretty interesting work by @chops310.bsky.social

TBKTS is also based mainly on the finding of one guy (vdK). Looks like a pattern to me!

The whole "trauma in the body" think is also currently debunked, in part, by former van der Kolk disciples. But I guess this is only the silence before the next mental health hypestorm.

Yeah I rarely see the same accounts actually admitting they were wrong. They exist - and there are also accounts that do a good job at debunking, but they often have very little followers. The social media algorithms seem to prefer BS over information…

Great debunk of the Polyvagal Theory by Paul Grossman was published some years ago in Biological Psychology. doi.org/10.1016/j.bi...

We are currently entering the great debunking phase on social media. These posts often come from the same accounts that celebrated polyvagal theory some time ago and recommended ear pressure points to PTSD patients.

I have to say, as long as you know what you're doing, Vibe is really useful for auxiliary tasks in the coding area. I'm currently using it to clean up a very messy directory from an R project; it's rewriting the paths for me, etc.
