牙科恐惧的测量是重要的，因为它的高患病率和可观的个人，临床和公共卫生后果。然而，现有的牙科焦虑和恐惧（牙科焦虑和恐惧）的措施有理论或实践上的局限性。本研究描述了一个新的成人量表的发展和随后的测试成绩的信度和效度的评估。牙科焦虑和恐惧指数（IDAF-4C（+））包含3个测量牙科焦虑和恐惧的模块。牙科恐惧症害怕牙齿刺激最后的8项测试模块（IDAF-4C）评估焦虑和恐惧反应的情感，行为，生理和认知成分。探索性因素分析支持量表维度的构建。IDAF-4C项目表现出良好的内部一致性（Cronbach的α = 0.94）和重测信度（r = 0.82）在4个月，和规模与其他牙科恐惧量表，以及牙科访问模式，避免牙医，牙科恐惧症的诊断密切相关。IDAF-4C的收敛和预测有效性与Corah的（1969; Corals. Gale，Illig，1978）牙科焦虑量表和牙科恐惧的单项测量，该量表预测了未来的牙科就诊和就诊感知。恐惧症和刺激模块都表现出强烈的和统计学上显着的关联与焦虑评分。总之，提供了足够的证据表明，新的比额表将是评估成年人口中吸毒情况的有用工具。IDAF-4C（+）是基于强大的理论基础，但规模是足够的实际应用在各种潜在的用途。
The measurement of dental fear is important due to its high prevalence and appreciable individual, clinical, and public health consequences. However, existing measures of dental anxiety and fear (DAF) have theoretical or practical limitations. This study describes the development and subsequent assessment of the reliability and validity of test scores of a new DAF scale for adults. The Index of Dental Anxiety and Fear (IDAF-4C(+)) contains 3 modules that measure DAF. dental phobia. and feared dental stimuli. The final 8-item DAF module (IDAF-4C) assesses emotional, behavioral, physiological, and cognitive components of the anxiety and fear response. The proposed scale dimensionality received support from exploratory factor analysis. IDAF-4C items showed good internal consistency (Cronbach's alpha = .94) and test-retest reliability at 4 months (r = .82), and the scale was strongly associated with other dental fear scales as well as with dental visiting patterns, avoidance of the dentist, and dental phobia diagnosis. The convergent and predictive validity of the IDAF-4C compared positively to Corah's (1969; Corals. Gale, Illig, 1978) Dental Anxiety Scale and a single-item measure of dental fear, and the scale predicted future dental visiting and visit perceptions. Both phobia and stimulus modules showed strong and statistically significant associations with DAF ratings. In all, sufficient evidence is provided to demonstrate that the new scale would be a useful tool to assess DAF in an adult population. The IDAF-4C(+) is based on strong theoretical underpinnings, yet the scale is practical enough for application across a variety of potential uses.
