Abstract

Although there are several ratings to assess Executive Functions (EF) in adults, most of these are lengthy and comprise items which describe extreme or pathologic behaviors (e.g., ADHD symptoms), proving inadequate for the assessment of EF in general population. The Adult Executive Functioning Inventory (ADEXI) seeks to assess EF taking these limitations into account. The aims of the present study were to analyze the factor structure, the convergent and divergent validity, and the reliability of a Spanish adaptation of the ADEXI in a non-clinical population. The Spanish adaptation of the ADEXI, the Interpersonal Reactivity Index (IRI), the Cognitive Flexibility Scale (CFS), and an adaptation of the Aggression Scale (AS) were administered to 369 healthy adults between 18 and 60-years-old. To analyze the factor structure of the ADEXI, Confirmatory Factor Analysis (CFA) was used. In addition, the relationship between the inventory and the IRI, the CFS and the AS was analyzed. Finally, Cronbach’s α index was calculated. CFA showed that the two-factor model including (1) Working memory and (2) Inhibition best fit the data. Significant correlations were found between the ADEXI scores and the CFS, the IRI and the AS, providing additional evidence of construct validity. The internal consistency of the ADEXI was high (α = 0.87). Taken together, our results indicate that the Spanish adaptation of the ADEXI shows satisfactory psychometric properties and would be a valid and reliable measure to assess EF in non-clinical populations both for clinical and research purposes.

摘要

尽管有多种评估成人执行功能 (EF) 的评级，但其中大部分都很冗长，并且包含描述极端或病态行为（例如 ADHD 症状）的项目，证明不足以评估一般人群的 EF。成人执行功能清单(ADEXI) 试图在考虑这些限制的情况下评估 EF。本研究的目的是分析因素结构、收敛和发散有效性，以及西班牙改编的 ADEXI 在非临床人群中的可靠性。西班牙版 ADEXI、人际反应指数(IRI)、认知灵活性量表(CFS) 和攻击性量表的改编版(AS) 对 369 名 18 至 60 岁的健康成年人进行了给药。为了分析 ADEXI 的因子结构，使用了验证性因子分析 (CFA)。此外，还分析了清单与 IRI、CFS 和 AS 之间的关系。最后计算Cronbach's α指数。CFA 表明，包括 (1) 工作记忆和 (2) 抑制在内的双因素模型最适合数据。在 ADEXI 分数和 CFS、IRI 和 AS 之间发现了显着的相关性，提供了结构有效性的额外证据。ADEXI 的内部一致性较高（α = 0.87）。综上所述，我们的结果表明，ADEXI 的西班牙版本显示出令人满意的心理测量特性，并且将是评估非临床人群 EF 的有效且可靠的措施，用于临床和研究目的。
