The Index of Dental Anxiety and Fear (IDAF-4C) is a theoretically derived test developed to allow clinicians and researchers to measure a person's level of dental fear. Population norms have not previously been made available for the IDAF-4C. The aim of this study was to provide Australian norms for the IDAF-4C using percentile ranks and to examine associations between scores and individual-level characteristics, dental avoidance and fear of pain.
A stratified random sample of 1511 Australian adults yielded complete questionnaire data for 1063 individuals (70.4%). Percentile ranks were calculated for IDAF-4C full scale scores stratified by age and gender.
IDAF-4C mean scores varied significantly by age, gender, income, and speaking a language other than English at home. Tables to convert raw scores to percentiles showed that full scale scores varied by age and gender. Scores on the IDAF-4C had strong and significant associations with avoidance of the dentist due to fear, average dental visiting frequency and anxiety about pain when going to the dentist.
Population norms allow clinicians or researchers to compare results for an individual or subgroup to the Australian population. It is recommended that a dental fear scale be used to screen all dental patients for dental fear to enable a more tailored and effective dental treatment experience.
牙科焦虑和恐惧指数（IDAF-4C）是一种理论上衍生的测试，旨在让临床医生和研究人员衡量一个人的牙科恐惧程度。以前没有提供过 IDAF-4C 的人群标准。本研究的目的是使用百分等级为澳大利亚人提供 IDAF-4C 的标准，并检查分数与个体特征、牙科回避和疼痛恐惧之间的关系。
对 1511 名澳大利亚成年人进行分层随机抽样，其中 1063 人（70.4%）完成了完整的问卷数据。按年龄和性别对 IDAF-4C 全量表得分进行分层，计算百分等级。
IDAF-4C 的平均分数因年龄、性别、收入以及在家中说英语以外的语言而有显著差异。将原始分数转换为百分位数的表格显示，全量表分数因年龄和性别而异。IDAF-4C 的分数与因恐惧而回避牙医、平均看牙频率以及去看牙医时对疼痛的焦虑有很强且显著的关联。
人群标准允许临床医生或研究人员将个体或亚组的结果与澳大利亚人群进行比较。建议使用牙科恐惧量表对所有牙科患者进行牙科恐惧筛查，以实现更具针对性和有效的牙科治疗体验。
