Psychiatrist, Cognitive-behavioural therapist, Clinical epidemiologist, who does systematic reviews, runs randomized clinical trials, performs meta-epidemiological studies and develops smartphone apps.
Randomized controlled trials (RCTs) and their meta-analyses remain the foundation of evidence-based psychotherapy, yet many of them are currently limited by methodological weaknesses, conceptual confusion, and interpretive challenges. authors.elsevier.com/a/1nfep%7E0r...

What Happens When You Bring Together 41 Israeli and Palestinian Teenagers at a Summer Camp in Greece?

But how could this SEM , with bidirectional arrows and without controlling for (time-dependent) confounders, show that anything is causing anything?

One-year follow-up of the RESiLIENT trial of smartphone CBT is out (n=3,280): CBT skills reduced major depression onset risk by 37–48%. But depression waxes and wanes. For the total burden of depression, behavioral activation + cognitive restructuring was the most effective. doi.org/10.1192/bjp....
📱 Could a smartphone app keep depression away — for nearly a year? A 3,280-person RCT says yes. CBT skills like behavioral activation & insomnia therapy cut the risk of major depression by up to 48% at 50 weeks. Prevention at scale is here. 🧵https://doi.org/10.1192/bjp.2026.10630

Thanks, Christian. Still get 403: Forbidden. Probably they do not allow access from outside the US.
odd. the link works fine for me. Try the below link nsduhweb.rti.org/respweb/home... and then click Survey Data -> Latest Survey Results. Or if that doesn't work just try googling National Survey on Drug Use and Health
Some evidence of decreasing depression rates among adolescents from the latest National Survey on Drug Use and Health. 60% of teens with depression reported receiving mental health treatment (31% taking meds) www.samhsa.gov/data/sites/d...
It appears that regulatory agencies are pretty ignorant of predictive/diagnostic modeling. A very similar thing happened with the Japanese PMDA.
FDA grants breakthrough device designation for schizophrenia/bipolar bloodtests, based on below paper with n=30 per disorder, "using 'leave-one-out' analyses, indicating that the models should be predictive when applied to independent data cohorts." Ouch. pmc.ncbi.nlm.nih.gov/articles/PMC...
But that is how education goes. We don’t have as many RCTs of educational methods, do we?
Universities: We teach critical thinking, and always ask for evidence, especially for extraordinary claims! 😤 Also universities 🫣:
After 40 years of working as psychiatrist and researcher, I cannot answer this question.
Oncology has made impressive progress since the 1970’s. Et tu, clinical psychology?
Can I just propose a sensitivity analysis called ‘excluding studies where researchers did not due their due diligence in fabricating the data”? Obvious fakes excluded?

This was a most illogical contrast one could ask. A clinician treats Mr A, and is interested in how they change over time. So a within-person change. But in deciding how to treat Mr A, the clinician must contrast Mr A receiving treatment X and not receiving it. Because we cannot do this (continue)
Clinical psychology depends on scientific evidence, but research from @chopwood.bsky.social et al. suggests that the kinds of data most commonly produced may not always align with what clinicians find most useful in practice. Read the article in American Psychologist: doi.org/10.1037/amp0...
It’s just another completely wrong use of the term statistical significant, don’t you think?
Agree. However, they found one significant interaction treatment x sex: a larger drug-placebo difference between men and women on day 2. HTE? Ore more likely a false positive finding, given there were 4 subscales of the MADRS and 6 time points and no adjustment of alpha pubpeer.com/publications...
I think they are even worse than that. They showed that sex is a prognostic factor. But they don't understand that prognostic factors essentially have no place in precision psychiatry. Precision psychiatry is about treatment*covariate interactions, i.e. about effect modifiers or HTE.
Precision psychiatry? Study on gender-specific esketamine response. Some gender diffs but irrespective of group (esk/placebo). Only one significant gender x treatment interaction, on a specific day, with a specific outcome: p = 0.02. It did not occur to authors that this is likely a false positive

Today we published a survey of the SWD (smallest worthwhile difference) of statins, which found that the median SWDs exceeded its actual efficacy across all risk scenarios, suggesting that laypeople demand greater benefits than statins typically provide. jamanetwork.com/journals/jam...
Measuring Public Preferences for Statin Therapy Using the Smallest Worthwhile Difference
This survey study uses the smallest worthwhile difference to assess US and Japanese individuals’ willingness to take statins based on expected risk-reduction benefits and burden.

In short, don’t dichotomize. It just gives the illusion of clarity, while losing information.
