执行障碍问卷（DEX，Wilson等人，执行障碍综合征的行为评估（Behavioral assessment of the dysexecutive syndrome，1996）是一种标准化的工具，用于测量执行障碍综合征可能导致的行为变化。尽管最初只是作为一种定性工具，但直接执行指数也越来越多地用于解决定量问题。到目前为止，还没有对问卷的测试质量进行更基本的统计分析。本研究基于191例获得性脑损伤患者的随机抽样，并报告了与项目质量、可靠性和DEX项目3的因子结构相关的数据，项目3显示出太大的项目难度，而项目11没有足够的区分力。DEX自评信度r = 0.85。除了提供测试的统计值之外，还根据四分位数标准对4个发现因素的总分和整个问卷进行临床严重程度分类。
The Dysexecutive Questionnaire (DEX, Wilson et al., Behavioral assessment of the dysexecutive syndrome, 1996) is a standardized instrument to measure possible behavioral changes as a result of the dysexecutive syndrome. Although initially intended only as a qualitative instrument, the DEX has also been used increasingly to address quantitative problems. Until now there have not been more fundamental statistical analyses of the questionnaire's testing quality. The present study is based on an unselected sample of 191 patients with acquired brain injury and reports on the data relating to the quality of the items, the reliability and the factorial structure of the DEX Item 3 displayed too great an item difficulty, whereas item 11 was not sufficiently discriminating. The DEX's reliability in self-rating is r = 0.85. In addition to presenting the statistical values of the tests, a clinical severity classification of the overall scores of the 4 found factors and of the questionnaire as a whole is carried out on the basis of quartile standards.
