Relationship between cognitive insight and attenuated delusional symptoms in individuals with at-risk mental state

Early intervention for everyone? A review of cross‐cultural issues and their treatment in ultra‐high‐risk (UHR) cohorts

“…Thirteen studies analysed the association of subcortical cerebral abnormalities with the severity of psychotic symptoms (Allen et al, 2016) or of cerebral dysfunction, bias and cognitive deficits with the risk of transition (Allen et al, 2012;Bramon et al, 2008;M. R. Broome et al, 2012;Goghari et al, 2014;Higuchi et al, 2013Higuchi et al, , 2014Kotlicka-Antczak et al, 2017;Klauser et al, 2015;Modinos et al, 2014;Uchida et al, 2014;Winton-Brown et al, 2015), whereas another examined the predictive role of stress biomarkers in the psychotic transition (Labad et al, 2015).…”

The relationship between cognitive insight and depression in psychosis and schizophrenia: A review and meta-analysis

“…4) can be useful in furthering the understanding of underlying cognitive mechanisms of both clinical and cognitive insight. Further, recent evidence has demonstrated that in patients with an "at risk mental state" (ARMS) there is a positive correlation between delusional thinking and SC scores, indicating that those with near psychotic-threshold delusional thinking had higher SC and thus more impaired cognitive insight (Uchida et al, 2014;Kimhy et al, 2014). Uchida et al (2014) also reported that ARMS patients scored significantly higher than healthy controls on the SC sub-scale.…”

Uchida et al (2014) also reported that ARMS patients scored significantly higher than healthy controls on the SC sub-scale. It could therefore be suggested that delusional thinking is related to cognitive insight because low SR and high SC, which produces a low BCIS-CI (composite index) score, result in a reasoning style that can maintain delusional beliefs.…”

Investigation of metamemory functioning in the at-risk mental state for psychosis

“…FEP patients were found to have a lower confidence gap (CG) and a higher KCI compared to HCs, similar to patients with chronic schizophrenia, in a source memory task . Uchida et al (2014) evaluated cognitive insight in ARMS patients using a questionnaire and found overconfidence to be related to attenuated delusional symptoms. Another study with HCs with high levels of paranoia found similar results in a visual perception task (Moritz et al 2014a).…”
