介绍。对前额叶回路改变引起的缺陷的研究几乎完全是从分类的角度进行的，这区分了正常功能和病理功能。然而，前额皮质的功能可以被视为一个连续的维度。执行障碍问卷 (DEX) 的创建目的是作为日常生活中“执行障碍综合征”症状的定性测量。目的。在广泛的非临床人群样本中探索自我报告的 DEX 的心理测量特性，以期提供可用于临床实践的解释。主题和方法。西班牙版本的 DEX 对居住在马德里、萨拉戈萨、阿斯图里亚斯、纳瓦拉和塞维利亚的 1013 名非临床个体（380 名男性和 633 名女性）进行了测试。结果。并行进行的析因研究揭示了存在两个具有足够一致性和内部效度指数的因素：探索开始、维持和组织行为的困难（无组织/冷漠）的项目和与在不适当的情况下中断行为（去抑制/冲动）相关的项目。根据年龄的分布与发育前提相匹配。建议采用以下分界点： < 10，最佳功能； 10-18，正常状态下的次优功能； 19-28，中度执行功能障碍，需要确定可能的原因，以及> 28，重要程度的执行障碍，包括严重的病理。结论。 DEX 可用作检测患有明显脑部疾病和执行功能缺陷但不存在任何已知或可识别病理的受试者的工具。
Introduction. Research on the deficits derived from alterations in the prefrontal circuits has been conducted almost exclusively from a categorical perspective, which differentiates normal from pathological functioning. The functioning of the prefrontal cortex, however, can be seen as a continuous dimension. The Dysexecutive Questionnaire (DEX) was created with the intention of being useful as a qualitative measure of the symptoms of 'dysexecutive syndrome' in day-today life.Aim. To explore the psychometric properties of the self-reported DEX in a broad sample of the non-clinical population with a view to providing interpretations that can be of use in clinical practice.Subjects and methods. The Spanish version of the DEX was administered to 1013 non-clinical individuals living in Madrid, Saragossa, Asturias, Navarre and Seville (380 males and 633 females).Results. The factorial study conducted in parallel reveals the existence of two factors with adequate consistency and internal validity indices: items that explore difficulties in beginning, maintaining and organising behaviour (disorganisation/apathy) and items related with the interruption of behaviour in situations where it is inappropriate (disinhibition/impulsivity). The distribution according to age matches the developmental premises. The following cut-off points are proposed: < 10, optimal functioning; 10-18, sub-optimal functioning within normality; 19-28, moderately dysexecutive functioning that requires identification of the possible causes, and > 28, important degree of dysexecutive disorder that would include severe pathologies.Conclusions. The DEX may be useful as an instrument for detecting subjects with demonstrable brain disorders and those with deficient executive functioning without the presence of any known or identifiable pathology.
