Ageism represents an important barrier to high-quality healthcare for older adults. The present study sought to translate and validate the Arabic version of the Ageism Scale for Dental Students (ASDS-Arabic).
The 27-item ASDS tool was translated from English into Arabic following recommended cross-sectional forward and backward translation guidelines. The translated version was subjected to the content validity ratio (CVR) and sent to dental students in 21 institutes from 10 different Arab countries. Principal components analysis (PCA) was used to assess the dimensionality of the scale, and Cronbach's alpha was used to determine internal consistency reliability. The discriminant validity of the scale was assessed using the independent t-test. Confirmatory factor analysis (CFA) was also undertaken.
Based on CVR, three items were removed. The 24-item Arabic version was completed by 3284 dental students. PCA and CFA retained 17 items in six components, explaining 50.3% of the total variance, with acceptable reliability, validity and discrimination. The first component "Adherence of older patients with dental treatment and instructions," included four items with a Cronbach α of 0.64 and scored 4.3 ± 0.8. The second component "Feasibility of the treatment plan," included three items with a Cronbach α of 0.66 and scored from 2.6 ± 1.2 to 2.9 ± 1.1. The third component "Cost of and responsibility for the dental treatment" included four items with a Cronbach α of 0.47 and scored 4.4 ± 0.8 to 4.5 ± 0.8. The fourth component "Medical history of older patients" included two items with a Cronbach α of 0.70 and scored 4.0 ± 1.0 to 4.1 ± 1.0. The fifth Component "Feeling towards older patients" included two items with a Cronbach α of 0.672 and scored 2.6 ± 1.2 to 2.0 ± 1.4. The sixth Component "Confidence and experience in treating older patients" included two items with a Cronbach α of 0.33 and scored 4.4 ± 1 to 4.6 ± 1.
This preliminary validation of the ASDS-Ar resulted in a new 17-item scale with six components with acceptable validity, reliability and discrimination.
年龄歧视是老年人获得高质量医疗保健的一个重要障碍。本研究旨在翻译并验证牙科学生年龄歧视量表的阿拉伯语版本（ASDS-阿拉伯语版）。
按照推荐的横断面正向和反向翻译指南，将包含27个条目的ASDS工具从英语翻译成阿拉伯语。翻译后的版本进行内容效度比（CVR）评估，并发送给来自10个不同阿拉伯国家21所院校的牙科学生。主成分分析（PCA）用于评估量表的维度，Cronbach's α用于确定内部一致性信度。使用独立t检验评估量表的区分效度。还进行了验证性因素分析（CFA）。
基于CVR，删除了3个条目。3284名牙科学生完成了包含24个条目的阿拉伯语版本。PCA和CFA保留了17个条目，分为六个成分，解释了总方差的50.3%，具有可接受的信度、效度和区分度。第一个成分“老年患者对牙科治疗和医嘱的依从性”，包含4个条目，Cronbach α为0.64，得分4.3±0.8。第二个成分“治疗计划的可行性”，包含3个条目，Cronbach α为0.66，得分从2.6±1.2到2.9±1.1。第三个成分“牙科治疗的成本和责任”包含4个条目，Cronbach α为0.47，得分4.4±0.8到4.5±0.8。第四个成分“老年患者的病史”包含2个条目，Cronbach α为0.70，得分4.0±1.0到4.1±1.0。第五个成分“对老年患者的感受”包含2个条目，Cronbach α为0.672，得分2.6±1.2到2.0±1.4。第六个成分“治疗老年患者的信心和经验”包含2个条目，Cronbach α为0.33，得分4.4±1到4.6±1。
对ASDS-Ar的这一初步验证产生了一个新的包含17个条目的量表，分为六个成分，具有可接受的效度、信度和区分度。
