Did you know that there’s only a single letter separating an “idionomic clinical workflow” from an “idiotnomic clinical workflow”? I haven’t managed to write my screed about cluster analysis yet, here’s another blog post in the meantime: www.the100.ci/2024/10/28/i...

There have been persistent calls spurring psychologists to do more “idiographic” research, starting even before Peter Molenaar’s “Manifesto on Psychology as Idiographic Science”, which is already 20 y...

My own contribution: as an alternative to structured PECAN, therapy recordings or notes can be analyzed with LLMs to generate a person specific networks

Josefine Schmitt: therapists and patients differ in how they think a network based case conceptualization should be done : therapists stress patients are experts, while patients prefer guidance

This is a simple but absolutely genius idea of a site!! It doesn't hit you with ai images (unless you ask), it does cite all the sources, and explains every step of conditional randomization. Absolutely brilliant!! (I died a toddler in the mud which is about right)

💡 Should we keep using the word 'symptom' in mental health research? In our opinion paper, Alberto Jover Martínez, Maaike Steenhuis, and I (shared first authors) explain why we think the term is problematic and suggest how to move forward. authors.elsevier.com/a/1nb3a_,1gY...

1/3 I think this is a nice use case for cross-sectional network analysis: to get a very basic idea of the nomological network of your target construct. In this case, we look at biopsychosocial risk & resilience factors for postpartum depression in n=57,518 women. osf.io/preprints/ps...

Yes exactly! Of course, this is an averaged group network and no single adolescent actually had this network . So that limits clinical application of this particular study :)

Lars Klintwall @larsklintwall.bsky.social · 17/11/2024
Totally agree! Also , the individual networks are way more interesting (the interview-version of the method has good enough reliability to look at individual adolescents)

Published! ”Perceived causal symptom network of adolescent mental health issues”. n = 55 depressed teenagers (PHQ9 > 9) picked symptoms from a predefined list (including criteria for depression, purple nodes), specified these in their own words, and then rated causal relations.
Symptom network showing that some nodes are more central than others: stress, procrastination and overthinking

And the network approach (which certainly has the potential to be used in therapy), was developed outside of psychology (kinda), right?

Brief and simple: Write sentences containing no more than one comma, and avoiding older and definitive expressions. Use everyday words instead of psychological jargon!

Test results and examples: Keep your lovely numbers in an appendix - only your colleagues will understand and parents and teachers will just get lost. Instead, give examples from the daily life of the child!

Lars Klintwall @larsklintwall.bsky.social · 10/11/2024
Structure: Instead of writing the assessment test-by-test or sources, structure the report around functional domains (e.g. impulsiveness, peer relations, and communication skills etc).
