Abstract：
OBJECTIVE: The goal of this study was to assess the validity of the Romanian version of the Index of Dental Anxiety and Fear (IDAF-4C+) questionnaire.
METHODS: This study was conducted on a convenience sample of past patients and their acquaintances through an online questionnaire administered on the Google Forms platform between May 2021 and September 2022. The sections of the survey were demographic characteristics, the dental anxiety scale questionnaire, the IDAF-4C+ questionnaire, a single question about dental fear, and previous dental treatments.
RESULTS: In total, 239 participants were included in the study, and the mean age was 37. The IDAF-4C questionnaire had good internal validity (Cronbach alpha was 0.945). The IDAF-4C had good convergent validity, and it was positively correlated with the dental anxiety scale (r = 0.825, p < 0.001) and the question about the fear of going to the dentist (r = 0.738, p < 0.001). The questionnaire had good reliability, and the intraclass correlation was 0.985. Lower levels of dental anxiety were associated with scaling, orthodontic treatment, and dental implants. A confirmatory factor analysis was conducted after the removal of the first question from the phobia module, and residual covariance was added between items four and nine of the stimulus module, showing a good fit for the retained questions of the IDAF-4C+, grouped by module.
CONCLUSIONS: The Romanian version of the IDAF-4C+ showed acceptable psychometric properties.

摘要：
目的：这项研究的目的是评估罗马尼亚版本的牙科焦虑和恐惧指数（IDAF-4C）问卷的有效性。
方法：本研究是通过2021年5月至2022年9月在GoogleForms平台上进行的在线问卷调查，对过去的患者及其熟人进行的便利样本。调查的部分是人口统计学特征，牙科焦虑量表，IDAF-4C+问卷，一个关于牙齿恐惧的问题，和以前的牙科治疗。
结果：总计，239名参与者被纳入研究，平均年龄是37岁.IDAF-4C问卷具有良好的内部效度(Cronbachα为0.945)。IDAF-4C具有良好的收敛有效性，与牙科焦虑量表（r=0.825，p<0.001）和对去牙医的恐惧问题（r=0.738，p<0.001）呈正相关。问卷具有较好的信度,组内相关性为0.985。较低水平的牙科焦虑与缩放有关，正畸治疗,和牙科植入物。从恐惧症模块中删除第一个问题后，进行了验证性因素分析，在刺激模块的第4项和第9项之间添加了残差协方差，很适合IDAF-4C+保留的问题，按模块分组。
结论：IDAF-4C+的罗马尼亚版本显示出可接受的心理测量特性。
