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...

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

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)

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.

Many SRs and CPGs included already or later retracted RCTs without caution. Most of them were never corrected. The scientific community, including publishers and researchers, should make systematic and concerted efforts to remove the impact of retracted RCTs.
