Eine weitere Stellungnahme der @dgps.bsky.social zum drohenden Kahlschlag durch Union und SPD. www.dgps.de/aktuelles/de...
dgps.de
Weitere geplante Änderungen im GKV-Beitragssatz Stabilisierungsgesetz gefährden eine evidenzbasierte psychotherapeutische Versorgung, die Ausbildung zukünftiger Psychotherapeut:innen und damit eine zentrale Säule der wissenschaftlichen Psychologie. Angesichts zunehmender psychischer Belastungen in Zeiten multipler Krisen braucht es eine Stärkung psychischer Gesundheit – nicht den Abbau bewährter Versorgungsstrukturen. Die Deutsche Gesellschaft für Psychologie (DGPs) appelliert daher, wissenschaftlich fundierte Psychotherapie langfristig zu sichern und verlässliche Perspektiven für Patientinnen und Patienten, psychotherapeutische Versorgung und die nächste Generation von Psychotherapeutinnen und Psychotherapeuten zu schaffen.

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >

Simulation studies have a conflict of interest problem. The same team: - develops a new method - designs a simulation study to evaluate it However, the new method has to show good performance to get published. We propose living synthetic benchmarks to address the issue (doi.org/10.48550/arX...).
