Establishing Clinical Cutoff Values for the Beck Cognitive Insight Scale
- 86 Downloads
Cognitive insight represents the ability to reflect on and criticize beliefs and thoughts, and is impaired in individuals with psychosis, relative to healthy controls. The Beck Cognitive Insight Scale is the most widely used tool to assess cognitive insight. While some studies have attempted to develop diagnostic cutoffs, clinical cutoffs differentiating levels of cognitive insight have not yet been established. We identified two clinical profiles within our psychosis sample (N = 385). Profiles represented low and high cognitive insight and were based on functioning and IQ. Composite index scores at the 33rd percentile in the low cluster and the 66th percentile in the high cluster were calculated. Composite index scores of three or lower represent low cognitive insight, between four and nine is considered moderate, and ten or above represents good cognitive insight. Clinical cutoffs will better orient clinicians and will facilitate the development of targeted interventions to improve cognitive insight.
