Impaired cognitive insight linked to delusions in psychosis risk


High levels of self-certainty, one aspect of cognitive insight, are associated with the presence of delusional symptoms in people with at-risk mental states (ARMS), a study shows.

The researchers, led by Tomohiro Uchida (Tohoku University Graduate School of Medicine, Sendai, Japan), suggest that “interventions that reduce overconfidence in their judgments or beliefs may be beneficial for individuals with ARMS.”

In particular, they say that studying the effect of cognitive behavioral therapy on cognitive insight in ARMS patients “would be intriguing.”
