Many questionnaires have been developed to measure dental anxiety and fear. Among them is the Index of Dental Anxiety and Fear Scale (IDAF-4C), which consists of a dental anxiety and fear module (IDAF-4C), a phobia module (IDAF-P) and a stimulus module (IDAF-S). The objective of this research was to report the adaptation and validation of the IDAF-4C for Malaysian secondary school children.
This was a cross-sectional validation study. The original English version of the IDAF-4C was translated into Malay, back-translated, and then sent for content validation via an expert validation and face validation by the target student population. Three hundred and seventy questionnaires were then distributed among 16-year-old school children. Confirmatory factor analysis (CFA) was conducted for the IDAF-4C module using a bootstrapped maximum likelihood estimator. Spearman's rank correlation was used to assess the relationship between the IDAF-S and IDAF-4C modules. Intraclass correlation (ICC) was used to determine the stability of the IDAF-S and IDAF-4C modules, while kappa values were used for the IDAF-P module.
The response rate was 86.5% for CFA and 76.9% for stability. CFA showed the existence of only one factor with a reliability estimate of 0.921, obtained via Raykov's procedure. All items in the IDAF-S module were significantly correlated with the IDAF-4C module ( < 0.001). The IDAF-S and IDAF-4C modules were stable, as determined via a two-way mixed model with absolute agreement, a single measure and a Case 3 ICC (A, 1). The IDAF-P module showed satisfactory stability, as assessed via kappa values.
The Malay version of the IDAF-4C is valid and reliable in measuring dental anxiety and fear among Malaysian secondary school children.
已经开发了许多问卷来测量牙科焦虑和恐惧。其中包括牙科焦虑和恐惧量表指数（IDAF - 4C），它由一个牙科焦虑和恐惧模块（IDAF - 4C）、一个恐惧症模块（IDAF - P）和一个刺激模块（IDAF - S）组成。本研究的目的是报告IDAF - 4C在马来西亚中学生中的改编和验证情况。
这是一项横断面验证研究。IDAF - 4C的原始英文版本被翻译成马来语，进行回译，然后通过专家验证和目标学生群体的面部验证进行内容验证。然后向16岁的在校儿童分发了370份问卷。使用自抽样最大似然估计器对IDAF - 4C模块进行验证性因素分析（CFA）。使用斯皮尔曼等级相关性来评估IDAF - S和IDAF - 4C模块之间的关系。使用组内相关性（ICC）来确定IDAF - S和IDAF - 4C模块的稳定性，而kappa值用于IDAF - P模块。
CFA的回复率为86.5%，稳定性的回复率为76.9%。CFA显示仅存在一个因素，通过雷科夫程序获得的可靠性估计值为0.921。IDAF - S模块中的所有项目与IDAF - 4C模块均显著相关（<0.001）。通过具有绝对一致性、单一测量和案例3 ICC（A，1）的双向混合模型确定，IDAF - S和IDAF - 4C模块是稳定的。通过kappa值评估，IDAF - P模块显示出令人满意的稳定性。
IDAF - 4C的马来语版本在测量马来西亚中学生的牙科焦虑和恐惧方面是有效且可靠的。
