Despite the widespread use of the clock-drawing test (CDT), normative data and information regarding the influence of sociodemographic factors on test performance by adult and elderly Israeli Arabs are lacking. The current study aimed to establish normative data for this population group by exploring the impact of sociodemographic factors such as age, education, and gender on CDT performance. In addition, this study examined the association between CDT performance and Mini-Mental State Examination (MMSE) scores.
The sample consisted of 295 community-dwelling healthy adult and elderly Israeli Arabs, aged 20-86 years, with a MMSE score ≥24. The MMSE and the CDT were administered to participants.
Statistical analyses revealed that age had a negative effect on CDT performance, which was most pronounced in the 60-86 age group, but education and occupation (academic vs non-academic) had a positive effect. Gender and place of residence (urban vs rural) had no effect. CDT performance predicted the MMSE score.
The present study provides preliminary normative data on adult and elderly Israeli Arabs. The CDT appears to be applicable to Israeli Arabs, while the normative data might help interpret cognitive function results in this population.
尽管画钟试验（CDT）被广泛使用，但缺乏关于以色列成年和老年阿拉伯人的规范性数据以及社会人口学因素对测试表现影响的信息。当前研究旨在通过探索年龄、教育程度和性别等社会人口学因素对画钟试验表现的影响，为这一人群建立规范性数据。此外，本研究还考察了画钟试验表现与简易精神状态检查表（MMSE）分数之间的关联。
样本包括295名居住在社区的健康成年和老年以色列阿拉伯人，年龄在20 - 86岁之间，简易精神状态检查表分数≥24。对参与者进行了简易精神状态检查表和画钟试验。
统计分析显示，年龄对画钟试验表现有负面影响，在60 - 86岁年龄组最为明显，但教育程度和职业（学术性与非学术性）有正面影响。性别和居住地点（城市与农村）没有影响。画钟试验表现可预测简易精神状态检查表分数。
本研究提供了关于成年和老年以色列阿拉伯人的初步规范性数据。画钟试验似乎适用于以色列阿拉伯人，而规范性数据可能有助于解释这一人群的认知功能结果。
