Objective
Self-assessment deficits, often referred to as impaired insight or unawareness of illness, are well established in people with schizophrenia. There are multiple levels of awareness, including awareness of symptoms, functional deficits, cognitive impairments, and the ability to monitor cognitive and functional performance in an ongoing manner. The present study aimed to evaluate the comparative predictive value of each aspect of awareness on the levels of everyday functioning in people with schizophrenia.
Method
We examined multiple aspects of self-assessment of functioning in 214 people with schizophrenia. We also collected information on everyday functioning rated by high contact clinicians and examined the importance of self-assessment for the prediction of real world functional outcomes. The relative impact of performance based measures of cognition, functional capacity, and metacognitive performance on everyday functioning was also examined.
Results
Misestimation of ability emerged as the strongest predictor of real world functioning and exceeded the influences of cognitive performance, functional capacity performance, and performance-based assessment of metacognitive monitoring. The relative contribution of the factors other than self-assessment varied according to which domain of everyday functioning was being examined, but in all cases, accounted for less predictive variance.
Conclusions
These results underscore the functional impact of misestimating one’s current functioning and relative level of ability. These findings are consistent with the use of insight-focused treatments and compensatory strategies designed to increase self-awareness in multiple functional domains.
Dr John M. Kane discusses cognitive impairments in schizophrenia with fellow expert Dr Philip D. Harvey and patient advocate and mental health clinician, Mr Carlos A. Larrauri, who was diagnosed with schizophrenia. The podcast aims to raise awareness of the unmet need to address cognitive impairments associated with schizophrenia (CIAS) as well as the challenges/opportunities faced by patients and clinicians regarding assessments and treatments. The authors emphasize the importance of a treatment focus on daily functioning, in parallel with cognitive symptoms, to mitigate impairments and improve overall outcomes. Mr Larrauri presents the patient perspective and shares his experiences of how psychosocial support and cognitive training can benefit recovery and help patients achieve their goals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
