对92名混合病因神经科患者和216名对照受试者进行了一系列神经心理测试，包括来自6个不同测试的10个执行功能神经心理测量。对患者有较好了解的人(亲属或照顾者)填写了一份关于患者日常生活中执行困难问题的问卷，并报告了这些测试对患者日常生活问题的预测程度。所有的测试都对患者照顾者报告的至少部分行为和认知缺陷具有重要的预测作用。然而，对患者执行困难症状的因素分析表明，执行困难综合症是一个细分，神经心理学测试对3个潜在的认知因素(抑制、意向性和执行记忆)进行了不同的加载，支持了不同测试测量不同认知过程的结论，然后可能限制了执行系统的细分。
Ninety-two mixed etiology neurological patients and 216 control participants were assessed on a range of neuropsychological tests, including 10 neuropsychological measures of executive function derived from 6 different tests. People who knew the patients well (relatives or carers) completed a questionnaire about the patient's dysexecutive problems in everyday life, and this paper reports the extent to which the tests predicted the patients' everyday life problems. All of the tests were significantly predictive of at least some of the behavioral and cognitive deficits reported by patients' carers. However, factor analysis of the patients' dysexecutive symptoms suggested a fractionation of the dysexecutive syndrome, with neuropsychological tests loading differentially on 3 underlying cognitive factors (Inhibition, Intentionality, and Executive Memory), supporting the conclusions that different tests measure different cognitive processes, and that then may be limits to the fractionation of the executive system.
