Though insight in schizophrenia is correlated with flexibility in abstract thought, it is unclear how differing dimensions of executive functions are linked to insight. Accordingly, the authors administered the Scale to Assess Unawareness of Mental Disorder and the Delis-Kaplan Executive Function System to 53 participants with schizophrenia spectrum disorders. Spearman Rho correlations revealed that symptom awareness was significantly related to Verbal Fluency, Color-Word, Tower, and Word Context scores. Awareness of treatment need was related to Color-Word, Tower, and Word Context tasks. Results suggest insight may be related to capacities to shift attention between differing environmental demands, plan ahead, and construct contextual understandings.
