Impaired introspective accuracy in schizophrenia: an independent predictor of functional outcomes
2019
Introduction: Individuals with schizophrenia present across a spectrum of symptomatology. Disability remains a debilitating reality across varying disease presentations and remains pervasive despite psychiatric medications. Cognition (neuro/social cognition) and negative symptoms have emerged as the strongest predictors of real-world disability, but account for <50% of the variance in outcomes.Methods: Our attempts to determine what accounts for the remaining 50% of variance has shown that poor introspective accuracy (IA) may be the most potent predictor of functional outcomes 25% of individuals with schizophrenia. We define IA as the adequacy of self-assessments of ability, skills, performance, or decisions. We suggest that IA is a progression of metacognition and can extend beyond cognition to include misestimation of prior and likely future performance in social or other adaptively relevant situations.Results: Additionally, IA is bidirectional and self-orientated. Emerging research has found th...
