Self-monitoring enhances Wisconsin Card Sorting Test performance in patients with schizophrenia: performance is improved by simply asking patients to verbalize their sorting strategy.

摘要: Patients with schizophrenia have Wisconsin Card Sorting Test (WCST) deficits, which are commonly interpreted as reflecting frontal cortex-based executive dysfunction. One means of assessing the refractoriness frontal-executive impairment is to utilize a training or modification strategy improve WCST performance. In this study, 73 patients were assigned 1 2 groups. Group received standard instructions for 64 cards (Condition 1). For second 64-card deck, asked verbalize reason that they placed card where did after each sort 2). modified instruction 1st 1) and then deck A group normal comparison participants was also tested using alone. committed significantly fewer perseverative responses than 1. Furthermore, there no significant difference between participants. 1's performance improved when exposed Additionally, poor premorbid factors disorganized symptoms associated decreased benefit from across both Cumulatively, these data suggest simple may enhance function impact in schizophrenia.
