Does structured, psychometrically based feedback discussion cause improvements of the therapeutic alliance? A single-case experimental study Routine outcome monitoring and feedback (ROM) systems have been established to enhance therapeutic outcomes, prevent drop-outs and facilitate data-driven personalization in psychotherapy. However, ...

🔥 New paper, led by my PhD student @selindem.bsky.social: preregistered single-case experimental study showing the positive impact of using the GPNS feedback system on the therapeutic alliance.

Only seen this paper this morning but I have emphasize how much this is a fantastic work ! I had a urge to go through this paper (too quickly unfortunately) and it was…wonderfull !!! The paper is open access so few quotes from the discussion that was music to my ears !!!

Another paper in our effort to get folks to stop routinely testing interactions. This time from the angle of stability. Led by @andrew-cast.bsky.social with help from @vizecolin.bsky.social, @jdmiller.bsky.social, @davidbaranger.bsky.social, and me. Forthcoming in AMPPS.

🚀 New paper (open access) out in Cognitive Therapy & Research: we (@herzog.bsky.social, @evalottabrakemeier.bsky.social, @hudsongolino.bsky.social and me) ask whether group‑level symptom‑change networks in CBT actually capture what happens inside each patient. #Psychology #CBT

What is currently being done to ensure that shared variance (i.e., symptoms) is not constantly confused with shared etiology (i.e., causes) in dimensional models of psychopathology? Asking because I read a certain preprint.

We built the openESM database:
▶️60 openly available experience sampling datasets (16K+ participants, 740K+ obs.) in one place
▶️Harmonized (meta-)data, fully open-source software
▶️Filter & search all data, simply download via R/Python

A randomized controlled trial testing the effects of sequential psychotherapy in depression: Changing therapist, or both therapist and method? This study examined the effectiveness of sequential psychotherapy strategies for adults with major depressive disorder who did not respond to an initi…

Does changing the therapist and/or method after non-response lead to better outcomes? Not according to this RCT.

Path Asymmetry in Complex Dynamic Systems of Psychopathology This article illustrates the assumption of path symmetry in current theories of psychopathology and calls for the development of dynamical systems of mental illness that incorporate asymmetry.

Thrilled to share a new paper in @jamapsychiatry.com on path asymmetry in complex dynamic systems of psychopathology! jamanetwork.com/journals/jam...

With amazing collaborators @tfblanken.bsky.social, Han van der Maas, & Denny Borsboom 🥳

💯!

Philipp argumentiert hier, dass wir mehr Deimplementation unwirksamer und schädlicher Methoden brauchen. Womöglich ist #SciCom nicht nur Kommunikation von Wissenschaft sondern auch Dekommunikation von Pseudowissenschaft.

So that is why you don't prompt people once a day for an entire year... #OpenESM - data from openesmdata.org/datasets/001...

Thank you for sharing our research! 🫶🏻

This is a really important paper. Strategies for deimplementation have received too little attention in psychotherapy to date, so it's good that this has now changed!

Thank you so much for your positive feedback! 🙏🏻

Differential effectiveness of dialectical behavioral therapy and schema therapy in patients with borderline personality disorder: a secondary analysis of a randomized clinical trial Borderline personality disorder (BPD) can be treated successfully with specific psychological treatments, but there is no clear evidence of superiorit…

New paper led by Nele Assmann, in which we used causal forests to test the heterogeneity of treatment effects of Schema Therapy vs. DBT for severe Borderline Personality Disorder.

Huge thanks to my brilliant 🦋-less co-author Carmen for refining my initial ideas and getting the framework into shape! 🙏🏻 3/3

We hope that this new approach will help to reduce the costs by low-value and inappropriate mental health care, thereby exerting a public health impact equally large as the uptake of evidence-based innovations. 2/3

🔥OUT NOW IN JCCP🔥: Over the moon to share a new conceptual piece in which Carmen McLean and I propose a potential #deimplementation framework targeting unsupported⚠️, proven ineffective⛔️, and potentially harmful therapies☠️. 1/3

What does it mean to be cool? 😎 A recent study in the Journal of Experimental Psychology: General with nearly 6,000 participants across 12 countries found remarkable agreement: cool people are adventurous, open, and powerful.

AI-generated ‘participants’ can lead social science experiments astray, study finds Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸

How about we reconsider the idea that sciencey science involves collecting own data.
