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).
