Debunking myths about the ineffectiveness of non-pharmacological approaches in treating psychosis.
Schizophrenia Bulletin published the results of a study confirming the efficacy of metacognitive training as part of a comprehensive treatment for schizophrenia. Link to the study
This randomized study demonstrated the effectiveness of a single session aimed at targeted correction of certain cognitive biases, specifically the "jumping-to-conclusions" bias. I'd like to emphasize the simplicity of the methodology used in this particular study (see image). We're not talking about a full-fledged psychotherapeutic process or training, but merely one session addressing a single, typical cognitive distortion seen in the spectrum of schizophrenic disorders.
The study found significant (d = 0.87-0.96) positive effects on the competence of patients in making independent decisions regarding their own treatment.
As a reminder, earlier this year a meta-analysis of 11 clinical studies (Link to the study) revealed a significant effect of metacognitive training on the severity of delusional disorders (g=-0.38), which persisted for at least six months (g=-0.35).
