PURPOSE/AIM: This work presents the preliminary validation of a novel scale assessing ageism attitudes among dental students.
A 27-question scale was created based on existing ageism scales. The new ageism scale was applied to 144 dental students. Content validity was achieved by experts' consensus. Questions whose deletion increased the overall α, loading < 0.40, loading on more than one factors, or those unexpectedly grouped in another factor were thoroughly examined. Principal Component Analysis assessed internal structure of the measure.
The final ageism scale included four items in a single factor that explained 58.5% of the overall variance with substantially higher reliability than other factors. The Cronbach's α for this single four-items factor was 0.75.
This preliminary analysis of a novel ageism scale for dental professionals pointed to four items achieving high reliability, providing guidance for a future definitive validation study with a larger sample.
目的/目标：本研究对一种评估牙科专业学生年龄歧视态度的新型量表进行初步验证。
基于现有的年龄歧视量表编制了一个包含27个问题的量表。将新的年龄歧视量表应用于144名牙科专业学生。通过专家共识实现内容效度。对那些删除后会提高总体α值、载荷<0.40、在多个因素上有载荷或意外归入另一个因素的问题进行了全面审查。主成分分析评估了该测量方法的内部结构。
最终的年龄歧视量表在单一因素中包含四个项目，该因素解释了总体方差的58.5%，可靠性明显高于其他因素。这个由四个项目组成的单一因素的克朗巴赫α系数为0.75。
对一种面向牙科专业人员的新型年龄歧视量表的初步分析表明，四个项目具有较高的可靠性，为未来更大样本的确定性验证研究提供了指导。
