The Adult Executive Functioning Inventory (ADEXI)-a short, practical, self-report questionnaire accessible across diverse adult populations and languages-was used to assess executive functions (EFs), primarily inhibition and working memory.
To examine the construct validity of the ADEXI Hebrew version through exploratory factor analysis (EFA) and convergent validity by correlating scores with similar measures of EF.
Cross-sectional study using online anonymous surveys.
Nonclinical sample of 239 adults, 74.1% women, ages 18 to 80 yr (Mage = 44.19 yr, SD = 12.89).
The Hebrew version of the 14-item ADEXI, a demographic questionnaire, and the Dysexecutive Questionnaire (DEX).
Descriptive statistics, Cronbach's α EFA using varimax rotation, and Pearson's correlations were used. Total internal consistency was good (α = .86). Unlike the two factors in the original English version, our construct validity through EFA revealed three factors-inhibition, working memory, and, uniquely, flexibility-that accounted for 55.71% of the variance. Convergent validity was supported by medium to large significant correlations (r =.29-.76) between the ADEXI and the DEX subscales and total scores.
Our findings offer psychometric evidence to support using the Hebrew version of the ADEXI for EF assessments in adult Hebrew-speaking populations. Plain-Language Summary: The Adult Executive Functioning Inventory (ADEXI) assesses three key components: inhibition, working memory, and cognitive flexibility. In this study, we examined the construct validity of the Hebrew version of the ADEXI to assess executive functions. Our findings support using the ADEXI in Hebrew-speaking populations. The ADEXI offers occupational therapy practitioners serving Hebrew-speaking populations in their practice a validated tool for assessing executive functions.
成人执行功能量表（ADEXI）是一种简短、实用、自我报告的问卷，适用于不同的成年人群体和语言，用于评估执行功能（EF），主要是抑制和工作记忆。
通过探索性因素分析（EFA）和与类似 EF 测量的相关性来检验 ADEXI 希伯来语版本的结构效度。
使用在线匿名调查的横断面研究。
239 名年龄在 18 至 80 岁的非临床成年人，74.1%为女性（平均年龄=44.19 岁，标准差=12.89 岁）。
使用描述性统计、最大方差旋转的 EFA 和 Pearson 相关系数进行分析。总内部一致性良好（α=.86）。与原始英语版本的两个因素不同，我们通过 EFA 得出的结构效度显示了三个因素——抑制、工作记忆，以及独特的灵活性——占总方差的 55.71%。ADEXI 与 DEX 分量表和总分之间存在中等至较大的显著相关性（r=.29-.76），支持了收敛效度。
我们的研究结果提供了心理测量学证据，支持在以希伯来语为母语的成年人中使用 ADEXI 评估执行功能。
