The aim of this study was to develop the Iranian version of the Children's Experiences of Dental Anxiety Measure (CEDAM) and evaluate its validity and reliability in assessing dental anxiety in children aged 9-16.
The CEDAM was translated into Persian following the guidelines of the IQOLA project. A sample of children completed the measure in a clinical setting, with a subgroup completing it again to assess test-retest reliability. Concurrent criterion validity was evaluated by having all participants complete the Modified Child Dental Anxiety Scale (MCDAS) alongside the CEDAM. Construct validity was examined using exploratory and confirmatory factor analyses. RESULTS: The study included 275 children between the ages of 9 and 16. The Iranian version of CEDAM exhibited excellent internal consistency with a Cronbach's ⍺ coefficient of 0.83. Test-retest reliability was also high, with an intraclass correlation coefficient value of 0.96. Furthermore, there was a significant and positive correlation between CEDAM and MCDAS scores (ρ = 0.72, p < .01). Exploratory factor analysis identified two factors, and confirmatory factor analysis confirmed that the instrument aligned well with the factor structure obtained from the exploratory analysis. CONCLUSION: This study provides evidence supporting the validity and reliability of the Iranian version of CEDAM as a valuable tool for evaluating dental anxiety in Persian-speaking children between the ages of 9 and 16..
本研究旨在开发伊朗版儿童牙科焦虑量表（CEDAM），并评估其在评估 9-16 岁儿童牙科焦虑症方面的有效性和可靠性。
根据 IQOLA 项目的指南，将 CEDAM 翻译成波斯语。一组儿童在临床环境中完成了该量表，其中一个亚组再次完成该量表以评估测试-重测信度。同时通过让所有参与者在完成 CEDAM 的同时完成改良儿童牙科焦虑量表（MCDAS）来评估效标关联效度。使用探索性和验证性因子分析来检验结构效度。
该研究共纳入 275 名 9-16 岁的儿童。CEDAM 的伊朗语版本表现出良好的内部一致性，克朗巴赫的 α 系数为 0.83。测试-重测信度也很高，组内相关系数值为 0.96。此外，CEDAM 和 MCDAS 评分之间存在显著正相关（ρ=0.72，p<.01）。探索性因子分析确定了两个因子，验证性因子分析证实该工具与从探索性分析中获得的因子结构一致。
本研究为伊朗版 CEDAM 的有效性和可靠性提供了证据，它是一种评估 9-16 岁讲波斯语儿童牙科焦虑症的有用工具。
