Dental anxiety is a common condition with severe consequences for oral health and health-related quality of life. The aim of this study was to evaluate the recently developed self-report scale Index of Dental Anxiety and Fear (IDAF-4C) in adults with severe dental anxiety. A sample of 147 adults (age 20-71 yr) with severe dental anxiety completed a questionnaire including the IDAF-4C and three other dental anxiety scales. In a clinically assessed subgroup (n = 93), 95% had an International classification of diseases and related health problems 10th version (ICD-10) diagnosis of specific phobia for dentistry. Agreement between the scales was analysed using Spearman's correlation, the Kappa measure of agreement and the intraclass correlation coefficient. The agreement of dental phobia according to the IDAF-4C phobia module and the ICD-10 was very low (ĸ = 0.02). The anxiety and fear module of the IDAF-4C showed acceptable agreement with the other scales (r 0.69-0.75; ICC 0.90, 95% CI 0.87-0.93). We conclude that the IDAF-4C offers more information to clinicians and researchers than the older dental anxiety scales, but the phobia module needs further development.
牙齿焦虑是一种常见的病症，会对口腔健康和与健康相关的生活质量产生严重影响。本研究的目的是评估新开发的用于评估严重牙齿焦虑症成年人的自我报告量表——牙齿焦虑和恐惧指数（IDAF-4C）。一个由 147 名成年人（年龄 20-71 岁）组成的样本完成了一份包括 IDAF-4C 和其他三种牙齿焦虑量表的问卷。在一个临床评估的亚组（n=93）中，95%的人有国际疾病分类和相关健康问题第十版（ICD-10）的牙科特定恐惧症诊断。使用 Spearman 相关系数、Kappa 一致性测量和组内相关系数分析量表之间的一致性。根据 IDAF-4C 的恐惧症模块和 ICD-10 对牙科恐惧症的一致性非常低（ĸ=0.02）。IDAF-4C 的焦虑和恐惧模块与其他量表具有可接受的一致性（r 0.69-0.75；ICC 0.90，95%CI 0.87-0.93）。我们得出的结论是，与较旧的牙齿焦虑量表相比，IDAF-4C 为临床医生和研究人员提供了更多信息，但恐惧症模块需要进一步开发。
